COCKAIGNE (COCKAYNE), LAND OF (O. Fr. _Coquaigne_, mod. Fr. _cocagne_, "abundance," from Ital. _Cocagna_; "as we say 'Lubberland,' the epicure's or glutton's home, the land of all delights, so taken in mockerie": Florio), an imaginary country, a medieval Utopia where life was a continual round of luxurious idleness. The origin of the Italian word has been much disputed. It seems safest to connect it, as do Grimm and Littré, ultimately with Lat. _coquere_, through a word meaning "cake," the literal sense thus being "The Land of Cakes." In Cockaigne the rivers were of wine, the houses were built of cake and barley-sugar, the streets were paved with pastry, and the shops supplied goods for nothing. Roast geese and fowls wandered about inviting folks to eat them, and buttered larks fell from the skies like manna. There is a 13th-century French _fabliau_, _Cocaigne_, which was possibly intended to ridicule the fable of the mythical Avalon, "the island of the Blest." The 13th-century English poem, _The Land of Cockaygne_, is a satire on monastic life. The term has been humorously applied to London, and by Boileau to the Paris of the rich. The word has been frequently confused with Cockney (q.v.).

See D. M. Méon, _Fabliaux et contes_ (4 vols., 1808), and F. J. Furnivall, _Early English Poems_ (Berlin, 1862).

COCKATOO (_Cacatuidae_), a family of parrots characterized among Old World forms by their usually greater size, by the crest of feathers on the head, which can be raised or depressed at will, and by the absence of green in their coloration. They inhabit the Indian Archipelago, New Guinea and Australia, and are gregarious, frequenting woods and feeding on seeds, fruits and the larvae of insects. Their note is generally harsh and unmusical, and although they are readily tamed when taken young, becoming familiar, and in some species showing remarkable intelligence, their powers of vocal imitation are usually limited. Of the true cockatoos (_Cacatua_) the best known is the sulphur-crested cockatoo (_Cacatua galerita_), of a pure white plumage with the exception of the crest, which is deep sulphur yellow, and of the ear and tail coverts, which are slightly tinged with yellow. The crest when erect stands 5 in. high. These birds are found in Australia in flocks varying from 100 to 1000 in number, and do great damage to newly-sown grain, for which reason they are mercilessly destroyed by farmers. They deposit their eggs--two in number, and of a pure white colour--in the hollows of decayed trees or in the fissures of rocks, according to the nature of the locality in which they reside. This is one of the species most usually kept in Europe as a cage bird. Leadbeater's Cockatoo (_Cacatua Leadbeateri_), an inhabitant of South Australia, excels all others in the beauty of its plumage, which consists in great part of white, tinged with rose colour, becoming a deep salmon colour under the wings, while the crest is bright crimson at the base, with a yellow spot in the centre and white at the tip. It is exceedingly shy and difficult of approach, and its note is more plaintive while less harsh than that of the preceding species. In the cockatoos belonging to the genus _Calyptorhynchus_ the general plumage is black or dark brown, usually with a large spot or band of red or yellow on the tail. The largest of these is known as the funereal cockatoo (_Calyptorhynchus funereus_), from the lugubrious note or call which it utters, resembling the two syllables Wy--la--, the native name of the species. It deposits its eggs in the hollows of the large gum-trees of Australia, and feeds largely on the larvae of insects, in search of which it peels off the bark of trees, and when thus employed it may be approached closely. The cockateel (_Calopsittacus novaehollandiae_), the only species in the family smaller than a pigeon, and with a long pointed tail, is a common aviary bird, and breeds freely in captivity.

COCKATRICE, a fabulous monster, the existence of which was firmly believed in throughout ancient and medieval times,--descriptions and figures of it appearing in the natural history works of such writers as Pliny and Aldrovandus, those of the latter published so late as the beginning of the 17th century. Produced from a cock's egg hatched by a serpent, it was believed to possess the most deadly powers, plants withering at its touch, and men and animals dying poisoned by its look. It stood in awe, however, of the cock, the sound of whose crowing killed it, and consequently travelers were wont to take this bird with them in travelling over regions supposed to abound in cockatrices. The weasel alone among mammals was unaffected by the glance of its evil eye, and attacked it at all times successfully; for when wounded by the monster's teeth it found a ready remedy in rue--the only plant which the cockatrice could not wither. This myth reminds one of the real contests between the weasel-like mungoos of India and the deadly cobra, in which the latter is generally killed. The term "cockatrice" is employed on four occasions in the English translation of the Bible, in all of which it denotes nothing more than an exceedingly venomous reptile; it seems also to be synonymous with "basilisk," the mythical king of serpents.

COCKBURN, SIR ALEXANDER JAMES EDMUND, 10th Bart. (1802-1880), lord chief justice of England, was born on the 24th of December 1802, of ancient Scottish stock. He was the son of Alexander, fourth son of Sir James Cockburn, 6th baronet, his three uncles, who had successively held the title, dying without heirs. His father was British envoy extraordinary and minister plenipotentiary to the state of Columbia, and married Yolande, daughter of the vicomte de Vignier. Young Alexander was at one time intended for the diplomatic service, and frequently during the legal career which he ultimately adopted he was able to make considerable use of the knowledge of foreign languages, especially French, with which birth and early education had equipped him. He was educated at Trinity Hall, Cambridge, of which he was elected a fellow, and afterwards an honorary fellow. He entered at the Middle Temple in 1825, and was called to the bar in 1829. He joined the western circuit, and for some time such practice as he was able to obtain lay at the Devon sessions, quarter sessions at that time affording an opening and a school of advocacy to young counsel not to be found anywhere fifty years later. In London he had so little to do that only the persuasion of friends induced him to keep his London chambers open. Three years after his call to the bar, however, the Reform Bill was passed, and the petitions which followed the ensuing general election gave rise to a large number of new questions for the decision of election committees, and afforded an opening of which he promptly availed himself. The decisions of the committees had not been reported since 1821, and with M. C. Rowe, another member of the western circuit, Cockburn undertook a new series of reports. They only published one volume, but the work was well done, and in 1833 Cockburn had his first parliamentary brief.

In 1834 Cockburn was well enough thought of to be made a member of the commission to inquire into the state of the corporations of England and Wales. Other parliamentary work followed; but he had ambition to be more than a parliamentary counsel, and attended diligently on his circuit, besides appearing before committees. In 1841 he was made a Q.C., and in that year a charge of simony, brought against his uncle, William, dean of York, enabled him to appear conspicuously in a case which attracted considerable public attention, the proceedings taking the form of a motion for prohibition duly obtained against the ecclesiastical court, which had deprived Dr Cockburn of his office. Not long after this, Sir Robert Peel's secretary, Edward Drummond, was shot by the crazy Scotsman, Daniel M'Naughten, and Cockburn, briefed on behalf of the assassin, not only made a very brilliant speech, which established the defence of insanity, but also secured the full publicity of a long report in the _Morning Chronicle_ of the 6th of March 1843. Another well-known trial in which he appeared a year later was that of _Wood_ v. _Peel_ (_The Times_, 2nd and 3rd of July 1844), the issue being in form to determine the winner of a bet (the Gaming Act was passed in the following year) as to the age of the Derby winner Running Rein--in substance to determine, if possible, the vexed question whether Running Rein was a four-year-old or a three-year-old when he was racing as the latter. Running Rein could not be produced by Mr Wood, and Baron Alderson took a strong view of this circumstance, so that Cockburn found himself on the losing side, while his strenuous advocacy of his client's cause had led him into making, in his opening speech, strictures on Lord George Bentinck's conduct in the case which had better have been reserved to a later stage. He was, however, a hard fighter, but not an unfair one--a little irritable at times, but on the whole a courteous gentleman, and his practice went on increasing.

In 1847 he decided to stand for parliament, and was elected without a contest Liberal M.P. for Southampton. His speech in the House of Commons on behalf of the government in the Don Pacifico dispute with Greece commended him to Lord John Russell, who appointed him solicitor-general in 1850 and attorney-general in 1851, a post which he held till the resignation of the ministry in February 1852. During the short administration of Lord Derby which followed, Sir Frederic Thesiger was attorney-general, and Cockburn was engaged against him in the case of _R._ v. _Newman_, on the prosecution of Achilli. This was the trial of a criminal information for libel filed against John Henry Newman, who had denounced a scandalous and profligate friar named Achilli, then lecturing on Roman Catholicism in England. Newman pleaded justification; but the jury who heard the case in the Queen's Bench, with Lord Campbell presiding, found that the justification was not proved except in one particular: a verdict which, together with the methods of the judge and the conduct of the audience, attracted considerable comment. The verdict was set aside, and a new trial ordered, but none ever took place. In December 1852, under Lord Aberdeen's ministry, Cockburn became again attorney-general, and so remained until 1856, taking part in many celebrated trials, such as the Hopwood Will Case in 1855, and the Swynfen Will Case, but notably leading for the crown in the trial of William Palmer of Rugeley in Staffordshire--an ex-medical man who had taken to the turf, and who had poisoned a friend of similar pursuits named Cook with strychnine, in order to obtain money from his estate by forgery and otherwise. Cockburn made an exhaustive study of the medical aspects of the case, and the prisoner's comment when convicted after a twelve days' trial was, alluding to the attorney-general's advocacy, "It was the riding that did it." In 1854 Cockburn was made recorder of Bristol. In 1856 he became chief justice of the common pleas. He inherited the baronetcy in 1858. In 1859 Lord Campbell became chancellor, and Cockburn became chief justice of the Queen's Bench, continuing as a judge for twenty-four years and dying in harness. On Friday, the 19th of November 1880, he tried causes with special juries at Westminster; on Saturday, the 20th, he presided over a court for the consideration of crown cases reserved; he walked home, and on that night he died of _angina pectoris_ at his house in Hertford Street.

Sir Alexander Cockburn earned and deserved a high reputation as a judge. He was a man of brilliant cleverness and rapid intuition rather than of profound and laboriously cultivated intellect. He had been a great advocate at the bar, with a charm of voice and manner, fluent and persuasive rather than learned; but before he died he was considered a good lawyer, some assigning his unquestioned improvement in this respect to his frequent association on the bench with Blackburn. He had notoriously little sympathy with the Judicature Acts. Many were of opinion that he was inclined to take an advocate's view of the cases before him, making up his mind as to their merits prematurely and, in consequence, wrongly, as well as giving undue prominence to the views which he so formed; but he was beyond doubt always in intention, and generally in fact, scrupulously fair. It is not necessary to enumerate the many _causes célèbres_ at which Sir Alexander Cockburn presided as a judge. It was thought that he went out of his way to arrange that they should come before him, and his successor, Lord Coleridge, writing in 1881 to Lord Bramwell, to make the offer that he should try the murderer Lefroy as a last judicial act before retiring, added, "Poor dear Cockburn would hardly have given you such a chance." Be this as it may, Cockburn tried all cases which came before him, whether great or small, with the same thoroughness, courtesy and dignity, so that no counsel or suitor could complain that he had not been fully heard in a matter in which the issues were seemingly trivial; while he certainly gave great attention to the elaboration of his judgments and charges to juries. He presided at the Tichborne trial at Bar, lasting 188 days, of which his summing-up occupied eighteen.

The greatest public occasion on which Sir Alexander Cockburn acted, outside his usual judicial functions, was that of the "Alabama" arbitration, held at Geneva in 1872, in which he represented the British government, and dissented from the view taken by the majority of the arbitrators, without being able to convince them. He prepared, with Mr C. F. Adams, the representative of the United States, the English translation of the award of the arbitrators, and published his reasons for dissenting in a vigorously worded document which did not meet with universal commendation. He admitted in substance the liability of England for the acts of the "Alabama," but not on the grounds on which the decision of the majority was based, and he held England not liable in respect of the "Florida" and the "Shenandoah."

In personal appearance Sir Alexander Cockburn was of small stature, but great dignity of deportment. He was fond of yachting and of sport, and was engaged in writing a series of articles on the "History of the Chase in the Nineteenth Century" at the time of his death. He was fond, too, of society, and was also throughout his life addicted to frivolities not altogether consistent with advancement in a learned profession, or with the positions of dignity which he successively occupied. At the same time he had a high sense of what was due to and expected from his profession; and his utterance upon the limitations of advocacy, in his speech at the banquet given in the Middle Temple Hall to M. Berryer, the celebrated French advocate, may be called the classical authority on the subject. Lord Brougham, replying for the guests other than Berryer, had spoken of "the first great duty of an advocate to reckon everything subordinate to the interests of his client." The lord chief justice, replying to the toast of "the judges of England," dissented from this sweeping statement, saying, amid loud cheers from a distinguished assembly of lawyers, "The arms which an advocate wields he ought to use as a warrior, not as an assassin. He ought to uphold the interests of his clients _per fas_, not _per nefas_. He ought to know how to reconcile the interests of his clients with the eternal interests of truth and justice" (_The Times_, 9th of November 1864). Sir Alexander Cockburn was never married, and the baronetcy became extinct at his death.

COCKBURN, ALICIA, or ALISON (1713-1794), Scottish poet, authoress of one of the most exquisite of Scottish ballads, the "Flowers of the Forest," was the daughter of Robert Rutherfurd of Fairnalee, Selkirkshire, and was born on the 8th of October 1713. There are two versions of this song,--the one by Mrs Cockburn, the other by Jean Elliot (1727-1805) of Minto. Both were founded on the remains of an ancient Border ballad. Mrs Cockburn's--that beginning "I've seen the smiling of Fortune beguiling"--is said to have been written before her marriage in 1731, though not published till 1765. Anyhow, it was composed many years before Jean Elliot's sister verses, written in 1756, beginning, "I've heard them liltin' at our ewe-milkin'." Robert Chambers states that the ballad was written on the occasion of a great commercial disaster which ruined the fortunes of some Selkirkshire lairds. Later biographers, however, think it probable that it was written on the departure to London of a certain John Aikman, between whom and Alison there appears to have been an early attachment. In 1731 Alison Rutherfurd was married to Patrick Cockburn of Ormiston. After her marriage she knew all the intellectual and aristocratic celebrities of her day. In the memorable year 1745 she vented her Whiggism in a squib upon Prince Charlie, and narrowly escaped being taken by the Highland guard as she was driving through Edinburgh in the family coach of the Keiths of Ravelston, with the parody in her pocket. Mrs Cockburn was an indefatigable letter-writer and a composer of parodies, squibs, toasts and "character-sketches"--then a favourite form of composition--like other wits of her day; but the "Flowers of the Forest" is the only thing she wrote that possesses great literary merit. At her house on Castle-hill, and afterwards in Crichton Street, she received many illustrious friends, among whom were Mackenzie, Robertson, Hume, Home, Monboddo, the Keiths of Ravelston, the Balcarres family and Lady Anne Barnard, the authoress of "Auld Robin Gray." As a Rutherfurd she was a connexion of Sir Walter Scott's mother, and was her intimate friend. Lockhart quotes a letter written by Mrs Cockburn in 1777, describing the conduct of little Walter Scott, then scarcely six years old, during a visit which she paid to his mother, when the child gave as a reason for his liking for Mrs Cockburn that she was a "virtuoso like himself." Mrs Cockburn died on the 22nd of November 1794.

COCKBURN, SIR GEORGE, Bart. (1772-1853), British admiral, second son of Sir James Cockburn, Bart., and uncle of Lord Chief Justice Cockburn, was born in London. He entered the navy in his ninth year. After serving on the home station, and in the East Indies and the Mediterranean, he assisted, as captain of the "Minerve" (38) at the blockade of Leghorn in 1796, and fought a gallant action with the Spanish frigate "Sabina" (40) which he took. He was present at the battle of Cape St Vincent. In 1809, in command of the naval force on shore, he contributed greatly to the reduction of Martinique, and signed the capitulation by which that island was handed over to the English; for his services on this occasion he received the thanks of the House of Commons. After service in the Scheldt and at the defence of Cadiz he was sent in 1811 on an unsuccessful mission for the reconciliation of Spain and her American colonies. He was made rear-admiral in 1812, and in 1813-14, as second in command to Warren, he took a prominent part in the American War, especially in the capture of Washington. Early in 1815 he received the order of the Bath, and in the autumn of the same year he carried out, in the "Northumberland" (74), the sentence of deportation to St Helena which had been passed upon Bonaparte. In 1818 he received the Grand Cross of his order, and was made a lord of the admiralty; and the same year he was returned to parliament for Portsmouth. He was promoted to the rank of vice-admiral in 1819, and to that of admiral in 1837; he became senior naval lord in 1841, and held office in that capacity till 1846. From 1827 he was a privy councillor. In 1851 he was made admiral of the fleet, and in 1852, a year before his death, inherited the family baronetcy from his elder brother, being himself succeeded by his brother William, dean of York, who died in 1858.

See O'Byrne, _Naval Biography_; W. James, _Naval History_; _Gentleman's Magazine_ for 1853.

COCKBURN, HENRY THOMAS (1779-1854), Scottish judge, with the style of Lord Cockburn, was born in Edinburgh on the 26th of October 1779. His father, a keen Tory, was a baron of the Scottish court of exchequer, and his mother was connected by marriage with Lord Melville. He was educated at the high school and the university of Edinburgh; and he was a member of the famous Speculative Society, to which Sir Walter Scott, Brougham and Jeffrey belonged. He entered the faculty of advocates in 1800, and attached himself, not to the party of his relatives, who could have afforded him most valuable patronage, but to the Whig or Liberal party, and that at a time when it held out few inducements to men ambitious of success in life. On the accession of Earl Grey's ministry in 1830 he became solicitor-general for Scotland. In 1834 he was raised to the bench, and on taking his seat as a judge in the court of session he adopted the title of Lord Cockburn. Cockburn's forensic style was remarkable for its clearness, pathos and simplicity; and his conversational powers were unrivalled among his contemporaries. The extent of his literary ability only became known after he had passed his seventieth year, on the publication of his biography of Lord Jeffrey in 1852, and from the _Memorials of his Time_, which appeared posthumously in 1856. He died on the 26th of April 1854, at his mansion of Bonaly, near Edinburgh.

COCKER, EDWARD (1631-1675), the reputed author of the famous _Arithmetick_, the popularity of which has added a phrase ("according to Cocker") to the list of English proverbialisms, was an English engraver, who also taught writing and arithmetic. He is credited with the authorship and execution of some fourteen sets of copy slips, one of which, _Daniel's Copy-Book, ingraven by Edward Cocker, Philomath_ (1664), is preserved in the British Museum. Pepys, in his _Diary_, makes very favourable mention of Cocker, who appears to have displayed great skill in his art. _Cocker's Arithmetick_, the fifty-second edition of which appeared in 1748, and which has passed through about 112 editions in all, was not published during the lifetime of its reputed author, the first impression bearing date of 1678. Augustus de Morgan in his _Arithmetical Books_ (1847) adduces proofs, which may be held to be conclusive, that the work was a forgery of the editor and publisher, John Hawkins; and there appears to be no doubt that the _Decimal Arithmetic_ (1684), and the _English Dictionary_ (second edition, 1715), issued by Hawkins under Cocker's name, are forgeries also. De Morgan condemns the _Arithmetick_ as a diffuse compilation from older and better works, and dates "a very great deterioration in elementary works on arithmetic" from the appearance of the book, which owed its celebrity far more to persistent puffing than to its merits. He pertinently adds,--"This same Edward Cocker must have had great reputation, since a bad book under his name pushed out the good ones."

COCKERELL, CHARLES ROBERT (1788-1863), British architect, was born in London on the 28th of April 1788. After a preliminary training in his profession, he went abroad in 1810 and studied the great architectural remains of Greece, Italy and Asia Minor. At Aegina, Phigalia and other places of interest, he conducted excavations on a large scale, enriching the British Museum with many fine fragments, and adding several valuable monographs to the literature of archaeology. Elected in 1829 an associate of the Royal Academy, he became a full member in 1836, and in 1839 he was appointed professor of architecture. On Sir John Soane's death in 1837 Cockerell was appointed architect of the Bank of England, and carried out the alterations that were judged to be necessary in that building. In addition to branch banks at Liverpool and Manchester he erected in 1840 the new library at Cambridge, and in 1845 the university galleries at Oxford, as well as the Sun and the Westminster Fire Offices in Bartholomew Lane and in the Strand; and he was joint architect of the London & Westminster Bank, Lothbury, with Sir W. Tite. On the death of Henry Lonsdale Elmes in 1847, Cockerell was selected to finish the St George's Hall, Liverpool. Cockerell's best conceptions were those inspired by classic models; his essays in the Gothic--the college at Lampeter, for instance, and the chapel at Harrow--are by no means so successful. His thorough knowledge of Gothic art, however, can be seen from his writings, _On the Iconography of Wells Cathedral_, and _On the Sculptures of Lincoln and Exeter Cathedrals_. In his _Tribute to the Memory of Sir Christopher Wren_ (1838) he published an interesting collection of the whole of Wren's works drawn to one scale.

COCKERILL, WILLIAM (1759-1832), Anglo-French inventor and machinist, was born in England in 1759. He went to Belgium as a simple mechanic, and in 1799 constructed at Verviers the first wool-carding and wool-spinning machines on the continent. In 1807 he established a large machine workshop at Liége. Orders soon poured in on him from all over Europe, and he amassed a large fortune. In 1810 he was granted the rights of naturalization by Napoleon I., and in 1812 handed over the management of his business to his youngest son, JOHN COCKERILL (1790-1840).

Thanks to his own energy and ability, aided by the influence of King William I. of the Netherlands, John Cockerill largely extended his father's business. King William secured him a site at Seraing, where he built large works, including an iron-foundry and blast furnace. The construction of the Belgian railways in 1834 gave a great impetus to these works, branches of which had already been opened in France, Germany and Poland. In 1838 Cockerill met with a carriage accident which nearly proved fatal, and the prospect of his loss resulted in the credit of the firm being so badly shaken that in 1839 it was compelled to go into liquidation, the liabilities being estimated at 26 millions of francs, the assets at 18 millions. This reverse, however, was only temporary. John Cockerill had practically concluded negotiations to construct the Russian government railways, when his constitution, undermined by overwork, broke down. He died at Warsaw on the 19th of June 1840. The iron works, among the largest in Europe, are still carried on under the name of La Société Cockerill at seraing (q.v.).

COCKERMOUTH, a market town in the Cockermouth parliamentary division of Cumberland, England, 27 m. S.W. of Carlisle, on the Cockermouth, Keswick & Penrith, the London & North Western, and the Maryport & Carlisle railways. Pop. of urban district (1901) 5355. It is pleasantly situated on the river Derwent, at the junction of the Cocker, outlying hills of the Lake District sheltering it on the north, east and south. The castle has remains of Norman work in the keep, and other ancient portions (including the gateway) of later date, but is in part modernized as a residence. The grammar school was founded in 1676. The county industrial school is established in the town. The industries include the manufacture of woollens and confectionery, tanning and engineering, and there is a considerable agricultural trade. There are coal mines in the neighbourhood. A statue was erected in 1875 to the sixth earl of Mayo, who represented the borough (abolished in 1885) from 1857 to 1868. There is a Roman fort a mile west of the town, at Papcastle.

Cockermouth (_Cokermuth_, _Cokermue_) was made the head of the honour or barony of Allerdale when that barony was created and granted to Waltheof in the early part of the 12th century. At a later date the honour of Allerdale was frequently called the honour of Cockermouth. Waltheof probably built the castle, under the shelter of which the town grew up. Although it never received any royal charter, the earliest records relating to Cockermouth mention it as a borough. In 1295 it returned two members to parliament and then not again until 1640. By the Representation of the People Act of 1867 the representation was reduced to one member, and by the Redistribution Act of 1885 it was disfranchised. In 1221 William de Fortibus, earl of Albemarle, was granted a Saturday market, which later in the year was transferred to Monday, the day on which it has continued to be held ever since. The Michaelmas Fair existed in 1343, and an inquisition dated 1374 mentions two horse-fairs on Whit-Monday and at Michaelmas. In 1638 Algernon Percy, earl of Northumberland, obtained a grant of a fair every Wednesday from the first week in May till Michaelmas. The chief sources of revenue in Norman times were the valuable fisheries and numerous mills.

COCK-FIGHTING, or COCKING, the sport of pitting game-cocks to fight, and breeding and training them for the purpose. The game-fowl is now probably the nearest to the Indian jungle-fowl (_Gallus ferrugineus_), from which all domestic fowls are believed to be descended. The sport was popular in ancient times in India, China, Persia and other eastern countries, and was introduced into Greece in the time of Themistocles. The latter, while moving with his army against the Persians, observed two cocks fighting desperately, and, stopping his troops, inspired them by calling their attention to the valour and obstinacy of the feathered warriors. In honour of the ensuing victory of the Greeks cock-fights were thenceforth held annually at Athens, at first in a patriotic and religious spirit, but afterwards purely for the love of the sport. Lucian makes Solon speak of quail-fighting and cocking, but he is evidently referring to a time later than that of Themistocles. From Athens the sport spread throughout Greece, Asia Minor and Sicily, the best cocks being bred in Alexandria, Delos, Rhodes and Tanagra. For a long time the Romans affected to despise this "Greek diversion," but ended by adopting it so enthusiastically that Columella (1st century A.D.) complained that its devotees often spent their whole patrimony in betting at the pit-side. The cocks were provided with iron spurs (_tela_), as in the East, and were often dosed with stimulants to make them fight more savagely.

From Rome cocking spread northwards, and, although opposed by the Christian church, nevertheless became popular in Great Britain, the Low Countries, Italy, Germany, Spain and her colonies. On account of adverse legislation cocking has practically died out everywhere excepting in Spain, countries of Spanish origin and the Orient, where it is still legal and extremely popular. It was probably introduced into England by the Romans before Caesar's time. William Fitz-Stephen first speaks of it in the time of Henry II. as a sport for school-boys on holidays, and particularly on Shrove Tuesday, the masters themselves directing the fights, or mains, from which they derived a material advantage, as the dead birds fell to them. It became very popular throughout England and Wales, as well as in Scotland, where it was introduced in 1681. Occasionally the authorities tried to repress it, especially Cromwell, who put an almost complete stop to it for a brief period, but the Restoration re-established it among the national-pastimes. Contemporary apologists do not, in the 17th century, consider its cruelty at all, but concern themselves solely with its justification as a source of pleasure. "If Leviathan took his sport in the waters, how much more may Man take his sport upon the land?" From the time of Henry VIII., who added the famous Royal Cock-pit to his palace of Whitehall, cocking was called the "royal diversion," and the Stuarts, particularly James I. and Charles II., were among its most enthusiastic devotees, their example being followed by the gentry down to the 19th century. Gervase Markham in his _Pleasures of Princes_ (1614) wrote "Of the Choyce, Ordring, Breeding and Dyeting of the fighting-Cocke for Battell," his quaint directions being of the most explicit nature. When a cock is to be trained for the pit he must be fed "three or foure daies only with old Maunchet (fine white bread) and spring water." He is then set to spar with another cock, "putting a payre of hots upon each of their heeles, which Hots are soft, bumbasted roules of Leather, covering their spurs, so that they cannot hurt each other.... Let them fight and buffet one another a good space." After exercise the bird must be put into a basket, covered with hay and set near the fire. "Then let him sweate, for the nature of this scowring is to bring away his grease, and to breed breath, and strength." If not killed in the fight, "the first thing you doe, you shall search his wounds, and as many as you can find you shall with your mouth sucke the blood out of them, then wash them with warm salt water,... give him a roule or two, and so stove him up as hot as you can."

Cocking-mains usually consisted of fights between an agreed number of pairs of birds, the majority of victories deciding the main; but there were two other varieties that aroused the particular ire of moralists. These were the "battle royal," in which a number of birds were "set," i.e. placed in the pit, at the same time, and allowed to remain until all but one, the victor, were killed or disabled; and the "Welsh main," in which eight pairs were matched, the eight victors being again paired, then four, and finally the last surviving pair. Among London cock-pits were those at Westminster, in Drury Lane, Jewin Street and Birdcage Walk (depicted by Hogarth). Over the royal pit at Whitehall presided the king's cockmaster. The pits were circular in shape with a matted stage about 20 ft. in diameter and surrounded by a barrier to keep the birds from falling off. Upon this barrier the first row of the audience leaned. Hardly a town in the kingdom was without its cockpit, which offered the sporting classes opportunities for betting not as yet sufficiently supplied by horse-racing. With the growth of the latter sport and the increased facilities for reaching the racing centres, cocking gradually declined, especially after parliament passed laws against it, so that gentlemen risked arrest by attending a main.

Among the best-known devotees of the sport was a Colonel Mordaunt, who, about 1780, took a number of the best English game-cocks to India. There he found the sport in high favour with the native rulers and his birds were beaten. Perhaps the most famous main in England took place at Lincoln in 1830 between the birds of Joseph Gilliver, the most celebrated breeder, or "feeder," of his day, and those of the earl of Derby. The conditions called for seven birds a side, and the stakes were 5000 guineas the main and 1000 guineas each match. The main was won by Gilliver by five matches to two. His grandson was also a breeder, and the blood of his cocks still runs in the best breeds of Great Britain and America. Another famous breeder was Dr Bellyse of Audlem, the principal figure in the great mains fought at Chester during race-week at the beginning of the 19th century. His favourite breed was the white pile, and "Cheshire piles" are still much-fancied birds. Others were Irish brown-reds, Lancashire black-reds and Staffordshire duns.

In Wales, as well as some parts of England, cocking-mains took place regularly in churchyards, and in many instances even inside the churches themselves. Sundays, wakes and church festivals were favourite occasions for them. The habit of holding mains in schools was common from the 12th to about the middle of the 19th century. When cocking was at its height, the pupils of many schools were made a special allowance for purchasing fighting-cocks, and parents were expected to contribute to the expenses of the annual main on Shrove Tuesday, this money being called "cockpence." Cock-fighting was prohibited by law in Great Britain in 1849.

Cocking was early introduced into America, though it was always frowned upon in New England. Some of the older states, as Massachusetts, forbade it by passing laws against cruelty as early as 1836, and it is now expressly prohibited in Canada and in most states of the Union, or is repressed by general laws for the prevention of cruelty to animals.

Cocks are fought at an age of from one to two years. "Heeling," or the proper fastening of the spurs, and "cutting out," trimming the wings at a slope, and cutting the tail down by one-third of its length and shortening the hackle and rump feathers, are arts acquired by experience. The comb is cut down close, so as to offer the least possible mark for the hostile bird's bill. The cock is then provided with either "short heels," spurs 1½ in. or less in length, or with "long heels," from 2 to 2½ in. in length. The training of a cock for the pit lasts from ten days to a month or more, during which time the bird is subjected to a rigid diet and exercise in running and sparring. The birds may not be touched after being set down in the pit, unless to extricate them from the matting. Whenever a bird refuses to fight longer he is set breast to breast with his adversary in the middle of the pit, and if he then still refuses to fight he is regarded as defeated. Among the favourite breeds may be mentioned the "Irish gilders," "Irish Grays," "Shawlnecks," "Gordons," "Eslin Red-Quills," "Baltimore Topknots," "Dominiques," "War-horses" and "Claibornes."

Cock-fighting possesses an extensive literature of its own. See Gervase Markham, _Pleasures of Princes_ (London, 1614); Blain, _Rural Sports_ (London, 1853); "Game Cocks and Cock-Fighting," _Outing_, vol. 39; "A Modest Commendation of Cock-Fighting," _Blackwood's Magazine_, vol. 22; "Cock-Fighting in Schools," _Chambers' Magazine_, vol. 65.

COCK LANE GHOST, a supposed apparition, the vagaries of which attracted extraordinary public attention in London during 1762. At a house in Cock Lane, Smithfield, tenanted by one Parsons, knockings and other noises were said to occur at night varied by the appearance of a luminous figure, alleged to be the ghost of a Mrs Kent who had died in the house some two years before. A thorough investigation revealed that Parsons' daughter, a child of eleven, was the source of the disturbance. The object of the Parsons family seems to have been to accuse the husband of the deceased woman of murdering her, with a view to blackmail. Parsons was prosecuted and condemned to the pillory. Among the crowds who visited the house was Dr Johnson, who was in consequence made the object of a scurrilous attack by the poet Charles Churchill in "The Ghost."

See A. Lang, _Cock Lane and Common Sense_ (1894).

COCKLE, SIR JAMES (1819-1895), English lawyer and mathematician, was born on the 14th of January 1819. He was the second son of James Cockle, a surgeon, of Great Oakley, Essex. Educated at Charterhouse and Trinity College, Cambridge, he entered the Middle Temple in 1838, practising as a special pleader in 1845 and being called in 1846. Joining the midland circuit, he acquired a good practice, and on the recommendation of Chief Justice Sir William Erle he was appointed chief justice of Queensland in 1863. He received the honour of knighthood in 1869, retired from the bench, and returned to England in 1879.

Cockle is more remembered for his mathematical and scientific investigations than as a lawyer. Like many young mathematicians he attacked the problem of resolving the higher algebraic equations, notwithstanding Abel's proof that a solution by radicles was impossible. In this field Cockle achieved some notable results, amongst which is his reproduction of Sir William R. Hamilton's modification of Abel's theorem. Algebraic forms were a favourite object of his studies, and he discovered and developed the theory of criticoids, or differential invariants; he also made contributions to the theory of differential equations. He displayed a keen interest in scientific societies. From 1863 to 1879 he was president of the Queensland Philosophical Society (now incorporated in the Royal Society of Queensland); on his return to England he became associated with the London Mathematical Society, of which he was president from 1886 to 1888, and the Royal Astronomical Society, serving as a member of the council from 1888 to 1892. He died in London on the 27th of January 1895.

A volume containing his scientific and mathematical researches made during the years 1864-1877 was presented to the British Museum in 1897 by his widow. See the obituary notice by the Rev. R. Harley in _Proc. Roy. Soc._ vol. 59.

COCKLE, in zoology, a mollusc (_Cardium_) of the class Lamellibranchia (q.v.). A very large number of species of _Cardium_ have been distinguished by conchologists. Besides the common species _Cardium edule_, two others occur in Britain, but are not sufficiently common to be of commercial importance. One of these is _C. echinatum_, which is larger than the common species, reaching 3 in. in diameter, and distinguished by the presence of spines along the ribs of the shell. The other is _C. norvegicum_, which is also somewhat larger than _C. edule_, is longer dorso-ventrally than broad, and is only faintly ribbed.

The two valves of the shell of the common cockle are similar to each other, and somewhat circular in outline. The beak or umbo of each valve is prominent and rounded, and a number of sharp ridges and furrows radiate from the apex to the free edge of the shell, which is crenated. The ligament is external, and the hinge carries cardinal teeth in each valve. The interior of the shell is remarkable for the absence of pearly lustre on its interior surface. The colour externally is reddish or yellowish. The pallial line, which is the line of attachment of the mantle parallel to the edge of the shell, is not indented by a sinus at the posterior end. In the entire animal the posterior end projects slightly more than the anterior from the region of the umbones.

The animal possesses two nearly equal adductor muscles. The edges of the mantle are united posteriorly except at the anal and branchial apertures, which are placed at the ends of two very short siphons or tubular prolongations of the mantle; the siphons bear a number of short tentacles, and many of these are furnished with eye-spots. The foot is very large and powerful; it can be protruded from the anterior aperture between the mantle edges, and its outer part is bent sharply forwards and terminates in a point. By means of this muscular foot the cockle burrows rapidly in the muddy sand of the sea-shore, and it can also when it is not buried perform considerable leaps by suddenly bending the foot. The foot has a byssus gland on its posterior surface.

On either side of the body between the mantle and the foot are two flat gills each composed of two lamellae. _Cardium_ belongs to the order of Lamellibranchia in which the gills present the maximum of complexity, the original vertical filaments of which they are composed being united by interfilamentar and interlamellar junctions. In other respects the anatomy of the cockle presents no important differences from that of a typical Lamellibranch. The sexes are distinct, and the generative opening is on the side of the body above the edge of the inner lamella of the inner gill. The eggs are minute, and pass out into the sea-water through the dorsal or exhalent siphon. The breeding season is April, May and June. The larva for a time swims freely in the sea-water, having a circlet of cilia round the body in front of the mouth, forming the velum. The shell is developed on the dorsal surface behind the velum, the foot on the opposite or ventral surface behind the mouth. After a few days, when the mantle bearing the shell valves has developed so much as to enclose the whole body, the young cockle sinks to the bottom and commences to follow the habits of the adult. The usual size of the cockle in its shell is from 1 to 2 in. in breadth.

The common cockle is regularly used as food by the poorer classes. It occurs in abundance on sandy shores in all estuaries. At the mouth of the Thames the gathering of cockles forms a considerable industry, especially at Leigh. On the coast of Lancashire also the fishery, if it may be so called, is of considerable importance. The cockles are gathered by the simple process of raking them from the sand, and they are usually boiled and extracted from their shells before being sent to market. The cockle is liable to the same suspicion as the oyster of conveying the contamination of typhoid fever where the shores are polluted, but as it is boiled before being eaten it is probably less dangerous. (J. T. C.)

COCKNEY, a colloquial name applied to Londoners generally, but more properly confined to those born in London, or more strictly still to those born within the sound of the bells of St Mary-le-Bow church. The origin of the word has been the subject of many guesses, from that in John Minsheu's lexicon, _Ductor in linguas_ (1617), which gives the tale of the town-bred child who, on hearing a horse neigh, asked whether a "cock neighed" too, to the confusion of the word with the name of the Utopia, the land of Cockaigne (q.v.). The historical examination of the various uses of "Cockney," by Sir James Murray (see _Academy_, 10th of May 1890, and the _New English Dictionary_, s.v.) clearly shows the true derivation. The earliest form of the word is _cokenay_ or _cokeney_, i.e. the _ey_ or egg, and _coken_, genitive plural of "cock," "cocks' eggs" being the name given to the small and malformed eggs sometimes laid by young hens, known in German as _Hahneneier_. An early quotation, in Langland's _Piers Plowman_, A. vii. 272, gives the combination of "cokeneyes" and bacon to make a "collop," or dish of eggs and bacon. The word then applied to a child overlong nursed by its mother, hence to a simpleton or milksop. Thus in Chaucer, _Reeve's Tale_, the word is used with _daf_, i.e. a fool. The particular application of the name as a term of contempt given by country folk to town-bred people, with their dandified airs and ignorance of country ways and country objects, is easy. Thus Robert Whittington or Whitinton (_fl._ 1520), speaks of the "cokneys" in such "great cytees as London, York, Perusy" (Perugia), showing the general use of the word. It was not till the beginning of the 17th century that "cockney" appears to be confined to the inhabitants of London.

The so-called "Cockney" accent or pronunciation has varied in type. In the first part of the 19th century, it was chiefly characterized by the substitution of a _v_ for a _w_, or vice versa. This has almost entirely disappeared, and the chief consonantal variation which exists is perhaps the change of _th_ to _f_ or _v_, as in "fing" for thing, or "favver" for father. This and the vowel-sound change from _ou_ to _ah_, as in "abaht" for "about," are only heard among the uneducated classes, and, together with other characteristic pronunciations, phrases and words, have been well illustrated in the so-called "coster" songs of Albert Chevalier. The most marked and widely-prevalent change of vowel sound is that of _ei_ for _ai_, so that "daily" becomes "dyly" and "may" becomes "my." This is sometimes so marked that it almost amounts to incapacity to distinguish the vowels _a_ and _i_, and is almost universal in large classes of the population of London. The name of the "Cockney School of Poetry" was applied in 1817 to the literary circle of which Leigh Hunt was the principal representative, though Keats also was aimed at. The articles in _Blackwood's Magazine_, in which the name appeared, have generally, but probably wrongly, been attributed to John Gibson Lockhart.

COCK-OF-THE-ROCK, the familiar name of the birds of the genus Rupicola (subfamily Rupicolinae) of the Cotingas (allied to the Manakins, q.v.), found in the Amazon valley. They are about the size of a pigeon, with orange-coloured plumage, a pronounced crest, and orange-red flesh, and build their nests on rock. The skins and feathers are highly valued for decoration.

COCKPIT, the term originally for an enclosed place in which the sport of cock-fighting (q.v.) was carried on. On the site of an old cockpit opposite Whitehall in London was a block of buildings used from the 17th century as offices by the treasury and the privy council, for which the old name survived till the early 19th century. The name was given also to a theatre in London, built in the early part of the 17th century on the site of Drury Lane theatre. As the place where the wounded in battle were tended, or where the junior officers consorted, the term was also formerly applied to a cabin used for these purposes on the lower deck of a man-of-war.

COCKROACH[1] (_Blattidae_), a family of orthopterous insects, distinguished by their flattened bodies, long thread-like antennae, and shining leathery integuments. Cockroaches are nocturnal creatures, secreting themselves in chinks and crevices about houses, issuing from their retreats when the lights are extinguished, and moving about with extraordinary rapidity in search of food. They are voracious and omnivorous, devouring, or at least damaging, whatever comes in their way, for all the species emit a disagreeable odour, which they communicate to whatever article of food or clothing they may touch.

The common cockroach (_Stilopyga orientalis_) is not indigenous to Europe, but is believed to have been introduced from the Levant in the cargoes of trading vessels. The wings in the male are shorter than the body; in the female they are rudimentary. The eggs, which are 16 in number, are deposited in a leathery capsule fixed by a gum-like substance to the abdomen of the female, and thus carried about till the young are ready to escape, when the capsule becomes softened by the emission of a fluid substance. The larvae are perfectly white at first and wingless, although in other respects not unlike their parents, but they are not mature insects until after the sixth casting of the skin.

The American cockroach (_Periplaneta americana_) is larger than the former, and is not uncommon in European seaports trading with America, being conveyed in cargoes of grain and other food produce. It is very abundant in the Zoological Gardens in London, where it occurs in conjunction with a much smaller imported species _Phyllodromia germanica_, which may also be seen in some of the cheaper restaurants.

In both of these species the females, as well as the males, are winged.

In addition to these noxious and obtrusive forms, England has a few indigenous species belonging to the genus _Ectobia_, which live under stones or fallen trees in fields and woods. The largest known species is the drummer of the West Indies (_Blabera gigantea_), so called from the tapping noise it makes on wood, sufficient, when joined in by several individuals, as usually happens, to break the slumbers of a household. It is about 2 in. long, with wings 3 in. in expanse, and forms one of the most noisome and injurious of insect pests. Wingless females of many tropical species present a close superficial resemblance to woodlice; and one interesting apterous form known as _Pseudoglomeris_, from the East Indies, is able to roll up like a millipede.

The best mode of destroying cockroaches is, when the fire and lights are extinguished at night, to lay some treacle on a piece of wood afloat on a broad basin of water. This proves a temptation to the vermin too great to be resisted. The chinks and holes from which they issue should also be filled up with unslaked lime, or painted with a mixture of borax and heated turpentine.

See generally Miall and Denny, _The Structure and Life History of the Cockroach_ (1887); G. H. Carpenter, _Insects: their Structure and Life_ (1899); Charles Lester Marlatt, _Household Insects_ (U.S. Department of Agriculture, revised edition, 1902); Leland Ossian Howard, _The Insect Book_ (1902).

FOOTNOTE:

[1] The word is a corruption of Sp. _cucaracha_. In America it is commonly abbreviated to "roach."

COCK'S-COMB, in botany, a cultivated form of _Celosia cristata_ (natural order Amarantaceae), in which the inflorescence is monstrous, forming a flat "fasciated" axis bearing numerous small flowers. The plant is a low-growing herbaceous annual, bearing a large, comb-like, dark red, scarlet or purplish mass of flowers. Seeds are sown in March or April in pans of rich, well-drained sandy soil, which are placed in a hot-bed at 65° to 70° in a moist atmosphere. The seedlings require plenty of light, and when large enough to handle are potted off and placed close to the glass in a frame under similar conditions. When the heads show they are shifted into 5-in. pots, which are plunged to their rims in ashes or coco-nut fibre refuse, in a hot-bed, as before, close to the glass; they are sparingly watered and more air admitted. The soil recommended is a half-rich sandy loam and half-rotten cow and stable manure mixed with a dash of silver sand. The other species of _Celosia_ cultivated are _C. pyramidalis_, with a pyramidal inflorescence, varying in colour in the great number of varieties, and _C. argentea_, with a dense white inflorescence. They require a similar cultural treatment to that given for _C. cristata_.

COCKTON, HENRY (1807-1853), English humorous novelist, was born in London on the 7th of December 1807. He published a number of volumes, but is best known as the author of _Valentine Vox, the Ventriloquist_ (1840) and _Sylvester Sound, the Somnambulist_ (1844). He died at Bury St Edmunds on the 26th of June 1853.

COCKX (or COCK), HIERONYMUS [JEROME] (1510-1570), Flemish painter and engraver, was born at Antwerp, and in 1545 was admitted to the Gild of St Luke as a painter. It is as an engraver, however, that he is famous, a number of portraits and subject-pictures by him, and reproductions of Flemish masters, being well known. His brother Matthys (1505-1552) was also a painter.

COCOA,[1] more properly CACAO, a valuable dietary substance yielded by the seeds of several small trees belonging to the genus _Theobroma_, of the natural order Sterculiaceae. The whole genus, which comprises twelve species, belongs to the tropical parts of the American continent; and although the cocoa of commerce is probably the produce of more than one species, by far the greatest and most valuable portion is obtained from _Theobroma Cacao_. The generic name is derived from [Greek: theos] (god) and [Greek: broma] (food), and was bestowed by Linnaeus as an indication of the high appreciation in which he held the beverage prepared from the seeds, which he considered to be a food fit for the gods.

The common cacao tree is of low stature, seldom exceeding 25 ft. in height, but it is taller in its native forests than it is in cultivated plantations. The leaves are large, smooth, and glossy, elliptic-oblong and tapering in form, growing principally at the ends of branches, but sometimes springing directly from the main trunk. The flowers are small, and occur in numerous clusters on the main branches and the trunk, a very marked peculiarity which gives the matured fruit the appearance of being artificially attached to the tree. Generally only a single fruit is matured from each cluster of flowers. When ripe the fruit or "pod" is elliptical-ovoid in form, from 7 to 10 in. in length and from 3 to 4½ in. in diameter. It has a hard, thick, leathery rind of a rich purplish-yellow colour, externally rough and marked with ten very distinct longitudinal ribs or elevations. The interior of the fruit has five cells, in each of which is a row of from 5 to 12 seeds embedded in a soft delicately pink acid pulp. Each fruit thus contains from 20 to 50 or more seeds, which constitute the raw cacao or "cacao beans" of commerce.

The tree appears to have been originally a native of the coast lands of the Gulf of Mexico and tropical South America as far south as the basin of the Amazon; but it can be cultivated in suitable situations within the 25th parallels of latitude. It flourishes best within the 15th parallels, at elevations ranging from near the sea-level up to about 2000 ft. in height. It is now cultivated in Mexico, Honduras, Guatemala, Nicaragua, Brazil, Peru, Ecuador, New Granada, Venezuela, Surinam, Guiana, and in many of the West Indian islands, particularly in Trinidad, San Domingo, Grenada, Cuba, Porto Rico and Jamaica. Away from America it has been introduced, and is cultivated on a large scale in West Africa, Ceylon and the Dutch East Indies.

_History._--The value of cacao was appreciated in its native country before the discovery of America by Europeans. The Spaniards found in use in Mexico a beverage known by the Aztec name of _chocolath_, from _choco_ (cacao) and _lath_ (water). W. H. Prescott records that the emperor Montezuma of Mexico was "exceedingly fond of it ... no less than 50 jars or pitchers being prepared for his own daily consumption; 2000 more were allowed for that of his household." Bags of cacao containing a specified number of beans were also a recognized form of currency in the country. The product was early introduced into Spain, and thence to other parts of Europe. The _Public Advertiser_ (London) of June 16, 1657, contains an announcement that "In Bishopgate St., in Queen's Head Alley, at a Frenchman's house, is an excellent West India drink, called chocolate, to be sold, where you may have it ready at any time, and also unmade at reasonable rates." Chocolate was a very fashionable beverage in the early part of the 18th century.

_Cultivated Varieties._--Numerous varieties of the cacao, i.e. of _Theobroma Cacao_, are recognized in cultivation. According to Dr P. Preuss, who has travelled extensively in the cacao producing countries of the world studying this crop, it is impossible to embody in a single table the characteristics of the world's varieties. A separate classification is needed for almost each country. In 1882 the Trinidad forms were classified by Sir D. Morris. This table was later revised by Mr J. H. Hart, and more recently Mr R. H. Lock studied the Ceylon varieties. As the Ceylon cacaos were obtained mainly from Trinidad, and as Mr Lock's results agree substantially with those of Sir D. Morris, they serve to illustrate the distinguishing characteristics of the West Indian and Ceylon forms. The main divisions are as follows:--

1. _Criollo._--Pods relatively thin-walled and soft, rough, pointed at apex. The seeds or beans are plump and of pale colour. The ripe pods may be either red (colorado) or yellow (amarillo).

2. _Forastero._--Pods relatively thick-walled and hard. The seeds vary in colour from pale to deep purple. Various varieties are recognized, such as cundeamor, amelonado, liso, calabacillo, differing in shape, colour and character of beans, &c., and of each of these again there may be a colorado and amarillo sub-variety. Of special interest is calabacillo, a variety with a smooth, small pod, and deep purple beans. It is considered by some to be sufficiently distinct to form a third type equivalent to criollo or forastero. Others again would raise amelonado to the rank of a distinct type. Of the above calabacillo is the hardiest and yields the least valuable beans; criollo is the most delicate and yields beans of the highest value, whilst forastero is intermediate in both respects. In general pale coloured beans are less bitter and more valuable than purple beans. Both, however, may occur in the same pod.

_Alligator_, or _lagarto cacao_, is the common name of a variety cultivated in Nicaragua, Guatemala, &c. Its pods are distinctly five-angled and beset with irregular, warty protuberances. Some regard it as a distinct species, _T. pentagona_, but others only as a variety of _T. Cacao_. Its produce is of high value.

_T. bicolor_, indigenous to Central America, is another species of some interest. It bears small, hard woody pods about 6 in. long and 3 in. in diameter, with curious surface markings. The beans possess a fetid odour and a bitter flavour and are known as "tiger cacao." It is not likely to become of great commercial importance, although consumed locally where found. "_Cacao bianco_" and "_pataste_" are other names for this species.

_Cultivation and Preparation._--Cacao requires for its successful cultivation a deep, well-watered and yet well-drained soil, shelter from strong winds, and a thoroughly tropical climate, with a mean annual temperature of about 80° F., a rainfall of from 50 to 100 or more in., and freedom from long droughts. Young plants are grown from seed, which may either be sown directly in the positions the future trees are to occupy, varying according to local circumstances from 6 to 25 ft. apart in all directions, or raised in nurseries and transplanted later. The latter course is desirable when it is necessary to water and otherwise tend the seedlings. However raised, the young plants require to be shaded, and this is usually done by planting bananas, cassava or other useful crops between the rows of cacao. In some countries, but not in all, permanent shade trees are planted amongst the cacao. Various leguminous trees are commonly used, e.g. the coral tree (_Erythrina_ spp.) sometimes known as _bois immortel_ and _madre del cacao_ or mother of cocoa, _Albizzia Lebbek_, _Pithecolobium Saman_, &c. The various rubber trees have been employed with success. Wind belts are also necessary in exposed situations.

Cacao comes into bearing when about five years old, the small pink flowers and the succeeding large pods being borne directly on the trunk and main branches. The pods are carefully picked when ripe, broken open, and the slimy mass of contained seeds and their enveloping mucilaginous pulp extracted. The "beans" are next fermented or "sweated," often in special houses constructed for the purpose, or by placing them in heaps and covering with leaves or earth, or in baskets, barrels, &c., lined with banana leaves. During fermentation the beans should be stirred once daily or oftener. The time of fermentation varies from one to twelve or even more days. Pale-coloured beans usually require less time than the deep purple and bitter kinds. The method adopted also considerably modifies the time required. The process of fermenting destroys the mucilage; the seeds lose to some degree their bitter flavour and their colour also changes: the pale criollo seeds, for example, developing a cinnamon-brown colour. The "fracture" of the beans also characteristically alters. Fermentation is not universally practised; the purple colour and bitter taste of unfermented cacao being wanted in some markets.

After the fermentation is completed the beans may or may not be washed, opinion as to the desirability of this process varying in different countries. In any case, however, they have to be dried and cured. When climatic conditions are favourable this is commonly done by spreading the beans in thin layers on barbecues, or stone drying floors, or otherwise exposing them to the sun. Sliding roofs or other means of rapidly affording shelter are desirable in case of showers, excessive heat, and also for protection at night. Artificial drying is now often resorted to and various patterns of drying houses are in use.

The appearance of the beans may often be improved by "claying," a very slight coating of red earth or clay being added. Polishing the beans also gives them a brighter appearance, removes mildew, and remnants of dried mucilage, &c. This may be done by "dancing the cacao," i.e. treading a heap with the bare feet, or by the use of special polishing machines. The cacao is now ready for shipment, and is usually packed in bags. Hamburg is the chief port in the world for cacao. Until quite recently, however, this position was held by Havre, which is now second in Europe. New York imports about the same amount as Havre. London follows next in importance.

_Cacao-producing Countries._--In the following table the production in tons (of 1000 kilos = 2205 lb) of the principal producing countries, arranged under continents, is given for 1905 and 1901. During this period the total world's production has increased by about 40%, as indicated in the summary below. Study of the table will show where the increase has taken place, but attention is directed especially to the rapid development in West Africa.

_Composition._--The relative weights of the various parts of a whole cacao pod are given thus by Prof. J. B. Harrison for British Guiana specimens:--

Calabacillo. Forastero. Husk 80.59 89.87 Pulp 7.61 4.23 Cuticles of the beans 1.77 0.50 Kernels of the beans 10.03 5.40 ------- ------- 100.00 100.00

The husk is composed mainly of water and cellulose woody tissue, with their usual mineral constituents, and has a low manurial value. The pulp contains sugars which become converted into alcohol during fermentation. Fibrous elements and water compose about six-tenths of the cuticles, which also contain approximately: albuminoids (6%), alkaloids (2%), fat (2%), sugars (6%), starch (7%), colouring matter (4%), tartaric acid (3%) and small quantities of various mineral constituents. The average composition of the kernels, according to Payen, is:--

Per cent. Fat (cacao butter) 50 Starch 10 Albuminoids 20 Water 12 Cellulose 2 Mineral matter 4 Theobromine 2 Colouring matter (cacao-red) trace ------- 100.00

_Manufacture of Cocoa and Chocolate._--The beans are cleaned and sorted to remove foreign bodies of all kinds and also graded into sizes to secure uniformity in roasting. The latter process is carried out in rotating iron drums in which the beans are heated to a temperature of about 260° to 280° F., and results in developing the aroma, partially converting the starch into dextrin, and eliminating bitter constituents. The beans also dry and their shells become crisp. In the next process the beans are gently crushed and winnowed, whereby the light shells are removed, and after removal by sifting of the "germs" the beans are left in the form of the irregular cocoa-nibs occasionally seen in shops. Cocoa-nibs may be infused with water and drunk, but for most people the beverage is too rich, containing the whole of the cacao-fat or cacao-butter. This fat is extracted from the carefully ground nibs by employing great hydraulic pressure in heated presses. The fat exudes and solidifies. When fresh it is yellowish-white, but becomes quite white on keeping. It is very valuable for pharmaceutical purposes and is a constituent of many pomades. With care it can be kept for a long time without going rancid.

After the extraction of the fat the resulting mass is ground to a fine powder when it is ready for use in the ordinary way. Many preparations on the market are of course not pure cocoa but contain admixtures of various starchy and other bodies.

The shells of the beans separated by the winnowing process contain theobromine, and their infusion with water is sometimes used as a substitute for coffee, under the name "miserabile." More recently they have been put to good account as a cattle food.

In the preparation of chocolate the preliminary processes of cleaning, sorting, roasting and removing the shells, and grinding the nibs, are followed as for cocoa. The fat, however, is not extracted, but sugar, and sometimes other materials also, are added to the ground pasty mass, together with suitable flavouring materials, as for example vanilla. The greatest care is taken in the process and elaborate grinding and mixing machinery employed. The final result is a semi-liquid mass which is moulded into the familiar tablets or other forms in which chocolate comes on the market.

Cocoa as a beverage has a similar action to tea and coffee, inasmuch as the physiological properties of all three are due to the alkaloids and volatile oils they contain. Tea and coffee both contain the alkaloid caffeine, whilst cocoa contains theobromine. In tea and coffee, however, we only drink an infusion of the leaves or seeds, whilst in cocoa the whole material is taken in a state of very fine suspension, and as the preceding analysis indicates, the cocoa bean, even with the fat extracted, is of high nutritive value.

_Cacao-consuming Countries._--The principal cacao-consuming countries are indicated below, which gives the imports into the countries named for 1905. These figures, as also those on production, are taken from _Der Gordian_.

Tons (1000 kilos). United States of America 34,958 Germany 29,663 France 21,748 United Kingdom 21,106 Holland 19,295 Spain 6,102 Switzerland 5,218 Belgium 3,019 Austria Hungary 2,668 Russia 2,230 Denmark 1,125 Italy 971 Sweden 900 Canada 700 Australia 600 Norway, Portugal and Finland 692 ------- Total 150,995

During recent years the use of cocoa has increased rapidly in some countries. The following table gives the increase per cent in consumption in 1905 over that in 1901 for the five chief consumers:--

FOOTNOTE:

[1] As a matter of nomenclature it is unfortunate that the corrupt form "cocoa," from a confusion with the coco-nut (q.v.), has become stereotyped. When introduced early in the 18th century it was as a trisyllable _co-co-a_, a mispronunciation of _cacao_ or _cocoa_, the Spanish adaptation from the Mexican _cacauatl_.

COCO DE MER, or DOUBLE COCO-NUT, a palm, _Lodoicea Sechellarum_, which is a native of the Seychelles Islands. The flowers are borne in enormous fleshy spadices, the male and female on distinct plants. The fruits, which are among the largest known, take ten years to ripen; they have a fleshy and fibrous envelope surrounding a hard nut-like portion which is generally two-lobed, suggesting a large double coco-nut. The contents of the nut are edible as in the coco-nut. The empty fruits (after germination of the seed) are found floating in the Indian Ocean, and were known long before the palm was discovered, giving rise to various stories as to their origin.

COCOMA, or CUCAMAS, a tribe of South American Indians living on the Marañon and lower Huallaga rivers, Peru. In 1681, at the time of the Jesuit missionaries' first visit, they had the custom of eating their dead and grinding the bones to a powder, which was mixed with a fermented liquor and drunk. When expostulated with by the Jesuits they said "it was better to be inside a friend than to be swallowed up by the cold earth." They are a provident, hard-working people, partly Christianized, and bolder than most of the civilized Indians. Their languages show affinity to the Tupi-Guarani stock.

COCO-NUT[1] PALM (_Cocos nucifera_), a very beautiful and lofty palm-tree, growing to a height of from 60 to 100 ft., with a cylindrical stem which attains a thickness of 2 ft. The tree terminates in a crown of graceful waving pinnate leaves. The leaf, which may attain to 20 ft. in length, consists of a strong mid-rib, whence numerous long acute leaflets spring, giving the whole the appearance of a gigantic feather. The flowers are arranged in branching spikes 5 or 6 ft. long, enclosed in a tough spathe, and the fruits mature in bunches of from 10 to 20. The fruits when mature are oblong, and triangular in cross section, measuring from 12 to 18 in. in length and 6 to 8 in. in diameter. The fruit consists of a thick external husk or rind of a fibrous structure, within which is the ordinary coco-nut of commerce. The nut has a very hard, woody shell, enclosing the nucleus or kernel, the true seed, within which again is a milky liquid called coco-nut milk. The palm is so widely disseminated throughout tropical countries that it is impossible to distinguish its original habitat. It flourishes with equal vigour on the coast of the East Indies, throughout the tropical islands of the Pacific, and in the West Indies and tropical America. It, however, attains its greatest luxuriance and vigour on the sea shore, and it is most at home in the innumerable small islands of the Pacific seas, of the vegetation of which it is eminently characteristic. Its wide distribution, and its existence in even the smallest coral islets of the Pacific, are due to the character of the fruit, which is eminently adapted for distribution by sea. The fibrous husk renders the fruit light and the leathery skin prevents water-logging. The seed will germinate readily on the sea-shore, the seedling growing out through the soft germ-pore on the upper end of the hard nut. The fruits dropping into the sea from trees growing on any shores would be carried by tides and currents to be cast up and to vegetate on distant coasts.

The coco-nut palm, being the most useful of its entire tribe to the natives of the regions in which it grows, and furnishing many valuable and important commercial products, is the subject of careful cultivation in many countries. On the Malabar and Coromandel coasts of India the trees grow in vast numbers; and in Ceylon, which is peculiarly well suited for their cultivation, it is estimated that twenty millions of the trees flourish. The wealth of a native in Ceylon is estimated by his property in coco-nut trees, and Sir J. Emerson Tennent noted a law case in a district court in which the subject in dispute was a claim to the 2520th part of ten of the precious palms. The cultivation of coco-nut plantations in Ceylon was thus described by Sir J. E. Tennent. "The first operation in coco-nut planting is the formation of a nursery, for which purpose the ripe nuts are placed in squares containing about 400 each; these are covered an inch deep with sand and seaweed or soft mud from the beach, and watered daily till they germinate. The nuts put down in April are sufficiently grown to be planted out before the rains of September, and they are then set out in holes 3 ft. deep and 20 to 30 ft. apart.... Before putting in the young plant it is customary to bed the roots with soft mud and seaweed, and for the first two years they must be watered and protected from the glare of the sun under shades made of the plaited fronds of the coco-nut palm, or the fan-like leaves of the palmyra." The palm begins to bear fruit from the fifth to the seventh year of its age, each stock carrying from 5 to 30 nuts, the tree maturing on an average 60 nuts yearly.

The uses to which the various parts of the coco-nut palm are applied in the regions of their growth are almost endless. The nuts supply no inconsiderable proportion of the food of the natives, and the milky juice enclosed within them forms a pleasant and refreshing drink. The juice drawn from the unexpanded flower spathes forms "toddy," which may be boiled down to sugar, or it is allowed to ferment and is distilled, when it yields a spirit which, in common with a like product from other sources, is known as "arrack." As in other palms, the young bud cut out of the top of the tree forms an esculent vegetable, "palm cabbage." The trunk yields a timber (known in European commerce as porcupine wood) which is used for building, furniture, firewood, &c.; the leaves are plaited into cajan fans and baskets, and used for thatching the roofs of houses; the shell of the nut is employed as a water-vessel; and the external husk or rind yields the coir fibre, with which are fabricated ropes, cordage, brushes, &c. The coco-nut palm also furnishes very important articles of external commerce, of which the principal is coco-nut oil. It is obtained by pressure or boiling from the kernels, which are first broken up into small pieces and dried in the sun, when they are known as copperah or _copra_. It is estimated that 1000 full-sized nuts will yield upwards of 500 lb. of copra, from which 25 gallons of oil should be obtained. The oil is a white solid substance at ordinary temperatures, with a peculiar, rather disagreeable odour, from the volatile fatty acids it contains, and a mild taste. Under pressure it separates into a liquid and a solid portion, the latter, coco-stearin, being extensively used in the manufacture of candles. Coco-nut oil is also used in the manufacture of marine soap, which forms a lather with sea-water. Coir is also an important article of commerce, being in large demand for the manufacture of coarse brushes, door mats and woven coir-matting for lobbies and passages. A considerable quantity of fresh nuts is imported, chiefly from the West Indies, into Britain and other countries; they are familiar as the reward of the popular English amusement of "throwing at the coco-nuts"; and the contents are either eaten raw or used as material for cakes, &c., or sweetmeats ("coker-nut").

FOOTNOTE:

[1] The spelling "cocoa-nut," which introduces a confusion with cocoa (q.v.) or cacao, is a corruption of the original Portuguese form, dating from (and largely due to) Johnson's _Dictionary_. The spelling "coker-nut," introduced to avoid the same ambiguity, is common in England.

COCYTUS (mod. _Vuvo_), a tributary of the Acheron, a river of Thesprotia (mod. _pashalik_ of Iannina), which flows into the Ionian Sea about 20 m. N. of the Gulf of Arta. The name is also applied in Greek mythology to a tributary of the Acheron or of the Styx, a river in Hades. The etymology suggested is from [Greek: kôkuein], to wail, in allusion to the cries of the dead. Virgil describes it as the river which surrounds the underworld (_Aen._ vi. 132).

COD, the name given to the typical fish of the family _Gadidae_, of the Teleostean suborder Anacanthini, the position of which has much varied in our classifications. Having no spines to their fins, the Gadids used, in Cuvierian days, to be associated with the herrings, Salmonids, pike, &c., in the artificially-conceived order of Malacopterygians, or soft-finned bony fishes. But, on the ground of their air-bladder being closed, or deprived of a pneumatic duct communicating with the digestive canal, such as is characteristic of the Malacopterygians, they were removed from them and placed with the flat-fishes, or _Pleuronectidae_, in a suborder Anacanthini, regarded as intermediate in position between the Acanthopterygians, or spiny-finned fishes, and the Malacopterygians. It has, however, been shown that the flat-fishes bear no relationship to the Gadids, but are most nearly akin to the John Dories (see DORY).

The suborder Anacanthini is, nevertheless, maintained for the _Muraenolepididae_ Gadids and two related families, _Macruridae_ and _Muraenolepididae_, and may be thus defined:--Air-bladder without open duct. Parietal bones separated by the supra-occipital; prootic and exoccipital separated by the enlarged opisthotic. Pectoral arch suspended from the skull: no mesocoracoid arch. Ventral fins below or in front of the pectorals, the pelvic bones posterior to the clavicular symphysis and only loosely attached to it by ligament. Fins without spines; caudal fin, if present, without expanded hypural, perfectly symmetrical, and supported by the neural and haemal spines of the posterior vertebrae, and by basal bones similar to those supporting the dorsal and anal rays. This type of caudal fin must be regarded as secondary, the _Gadidae_ being, no doubt, derived from fishes in which the homocercal fin of the typical Teleostean had been lost.

About 120 species of Gadids are distinguished, mostly marine, many being adapted to life at great depths; all are carnivorous. They inhabit chiefly the northern seas, but many abyssal forms occur between the tropics and in the southern parts of the Atlantic and Pacific. They are represented in British waters by eight genera, and about twenty species, only one of which, the burbot (_Lota vulgaris_), is an inhabitant of fresh waters. Several of the marine species are of first-rate economic importance. The genus _Gadus_ is characterized by having three dorsal and two anal fins, and a truncated or notched caudal fin. In the cod and haddock the base of the first anal fin is not, or but slightly, longer than that of the second dorsal fin; in the whiting, pout, coal-fish, pollack, hake, ling and burbot, the former is considerably longer than the latter.

The cod, _Gadus morrhua_, possesses, in common with the other members of the genus, three dorsal and two anal fins, and a single barbel, at least half as long as the eye, at the chin. It is a widely-distributed species, being found throughout the northern and temperate seas of Europe, Asia and America, extending as far south as Gibraltar, but not entering the Mediterranean, and inhabits water from 25 to 50 fathoms deep, where it always feeds close to the bottom. It is exceedingly voracious, feeding on the smaller denizens of the ocean--fish, crustaceans, worms and molluscs, and greedily taking almost any bait the fisherman chooses to employ. The cod spawns in February, and is exceedingly prolific, the roe of a single female having been known to contain upwards of eight millions of ova, and to form more than half the weight of the entire fish. Only a small proportion of these get fertilized, and still fewer ever emerge from the egg. The number of cod is still further reduced by the trade carried on in roe, large quantities of which are used in France as ground-bait in the sardine fishery, while it also forms an article of human food. The young are about an inch in length by the end of spring, but are not fit for the market till the second year, and it has been stated that they do not reach maturity, as shown by the power of reproduction, till the end of their third year. They usually measure about 3 ft. in length, and weigh from 12 to 20 lb, but specimens have been taken from 50 to 70 lb in weight.

As an article of food the cod-fish is in greatest perfection during the three months preceding Christmas. It is caught on all parts of the British and Irish coasts, but the Dogger Bank, and Rockall, off the Outer Hebrides, have been specially noted for their cod-fisheries. The fishery is also carried on along the coast of Norfolk and Suffolk, where great quantities of the fish are caught with hook and line, and conveyed to market alive in "well-boats" specially built for this traffic. Such boats have been in use since the beginning of the 18th century. The most important cod-fishery in the world is that which has been prosecuted for centuries on the Newfoundland banks, where it is not uncommon for a single fisherman to take over 500 of these fish in ten or eleven hours. These, salted and dried, are exported to all parts of the world, and form, when taken in connexion with the enormous quantity of fresh cod consumed, a valuable addition to the food resources of the human race.

The air-bladder of this fish furnishes isinglass, little, if at all, inferior to that obtained from the sturgeon, while from the liver is obtained cod-liver oil, largely used in medicine as a remedy in scrofulous complaints and pulmonary consumption (see Cod-liver Oil). "The Norwegians," says Cuvier, "give cod-heads with marine plants to their cows for the purpose of producing a greater proportion of milk. The vertebrae, the ribs, and the bones in general, are given to their cattle by the Icelanders, and by the Kamtchatdales to their dogs. These same parts, properly dried, are also employed as fuel in the desolate steppes of the Icy Sea."

At Port Logan in Wigtonshire cod-fish are kept in a large reservoir, scooped out of the solid rock by the action of the sea, egress from which is prevented by a barrier of stones, which does not prevent the free access of the water. These cod are fed chiefly on mussels, and when the keeper approaches to feed them they may be seen rising to the surface in hundreds and eagerly seeking the edge. They have become comparatively tame and familiar. Frank Buckland, who visited the place, states that after a little while they allowed him to take hold of them, scratch them on the back, and play with them in various ways. Their flavour is considered superior to that of the cod taken in the open sea. (G. A. B.)

CODA (Ital. for "tail"; from the Lat. _cauda_), in music, a term for a passage which brings a movement or a separate piece to a conclusion. This developed from the simple chords of a cadence into an elaborate and independent form. In a series of variations on a theme or in a composition with a fixed order of subjects, the "coda" is a passage sufficiently contrasted with the conclusions of the separate variations or subjects, added to form a complete conclusion to the whole. Beethoven raised the "coda" to a feature of the highest importance.

CODE (Lat. _codex_), the term for a complete and systematic body of law, or a complete and exclusive statement of some portion of the law; and so by analogy for any system of rules or doctrine; also for an arrangement in telegraphy, signalling, &c., by which communications may be made according to rules adopted for brevity or secrecy.

In jurisprudence the question of the reduction of laws to written codes, representing a complete and readily accessible system, is a matter of great historical and practical interest. Many collections of laws, however, which are commonly known as codes,[1] would not correspond to the definition given above. The Code of Justinian (see JUSTINIAN I.; ROMAN LAW), the most celebrated of all, is not in itself a complete and exclusive system of law. It is a collection of imperial constitutions, just as the Pandects are a collection of the opinions of jurisconsults. The Code and the Pandects together being, as Austin says, "digests of Roman law in force at the time of their conception," would, if properly arranged, constitute a code. Codification in this sense is merely a question of the _form_ of the laws, and has nothing to do with their goodness or badness from an ethical or political point of view. Sometimes codification only means the changing of unwritten into written law; in the stricter sense it means the changing of unwritten or badly-written law into law well written.

The same causes which made collections of laws necessary in the time of Justinian have led to similar undertakings among modern peoples. The actual condition of laws until the period when they are consciously remodelled is one of confusion, contradiction, repetition and disorder; and to these evils the progress of society adds the burden of perpetually increasing legislation. Some attempt must be made to simplify the task of learning the laws by improving their expression and arrangement. This is by no means an easy task in any country, but in England it is surrounded with peculiar difficulties. The independent character of English law has prevented an attempt to do what has already been done for other systems which have the basis of the Roman law to fall back upon.

The most celebrated modern code is the French. The necessity of a code in France was mainly caused by the immense number of separate systems of jurisprudence existing in that country before 1789, justifying Voltaire's sarcasm that a traveller in France had to change laws about as often as he changed horses. At first published under the title of _Code Civil des Français_, it was afterwards entitled the _Code Napoléon_ (q.v.)--the emperor Napoleon wishing to attach his name to a work which he regarded as the greatest glory of his reign. The code, it has been said, is the product of Roman and customary law, together with the ordinances of the kings and the laws of the Revolution. In form it has passed through several changes caused by the political vicissitudes of the country, and it has of course suffered from time to time important alterations in substance, but it still remains virtually the same in principle as it left the hands of its framers. The code has produced a vast number of commentaries, among which may be named those of A. Duranton, R. T. Troplong and J. C. F. Demolombe. The remaining French codes are the _Code de procédure civile_, the _Code de commerce_, the _Code d'instruction criminelle_ and the _Code pénal_. The merits of the French code have entered into the discussion on the general question of codification. Austin agrees with Savigny in condemning the ignorance and haste with which it was compiled. "It contains," says Austin, "no definitions of technical terms (even the most leading), no exposition of the _rationale_ of distinctions (even the most leading), no exposition of the broad principles and rules to which the narrower provisions expressed in the code are subordinate; hence its fallacious brevity." Codes modelled on the French code have, however, taken firm root in most of the countries of continental Europe and in other parts of the world as well, such as Latin America and several of the British colonies.

The Prussian code (_Code Frédéric_) was published by Frederick the Great in 1751. It was intended to take the place of "Roman, common Saxon and other foreign subsidiary laws and statutes," the provincial laws remaining in force as before. One of the objects of the king was to destroy the power of the advocates, whom he hoped to render useless. This, with other systems of law existing in Germany, has been replaced by the Civil Code of 1900 (see GERMANY).

The object of all these codes has been to frame a common system to take the place of several systems of law, rather than to restate in an exact and exhaustive form the whole laws of a nation, which is the problem of English codification. The French and Prussian codes, although they have been of great service in simplifying the law, have failed to prevent outside themselves that accumulation of judiciary and statute law which in England has been the chief motive for codification. A more exact parallel to the English problem may be found in the _Code of the State of New York_. The revised constitution of the state, as adopted in 1846, "ordered the appointment of two commissions, one to reduce into a written and a systematic code the whole body of the law of the state, and the other to revise, reform, simplify and abridge the rules and practice, pleadings, &c., of the courts of record." By an act of 1847, the state legislature declared that the body of substantive law should be contained in three codes--the Political, the Civil and the Penal. The works of both commissions, completed in 1865, filled six volumes, containing the Code of Civil Procedure (including the law of evidence), the Book of Forms, the Code of Criminal Procedure, the Political Code, the Penal Code and the Civil Code. In the introduction to the Civil Code it was claimed that in many departments of the law the codes "provided for every possible case, so that when a new case arises it is better that it should be provided for by new legislation." The New York code was defective in the important points of definition and arrangement. It formed the basis, however, of the present codes of civil and criminal procedure in the state of New York. Much interest has attached to the Penal Code drawn up by Edward Livingston (q.v.) for the state of Louisiana. The system consists of a Code of Crime and Punishments, a Code of Procedure, a Code of Evidence, a Code of Reform and Prison Discipline, and a Book of Definitions. "Though the state for which the codes were prepared," said Chief Justice Chase, "neglected to avail itself of the labours assigned and solicited by itself, they have proved, together with their introductions, a treasure of suggestions to which many states are indebted for useful legislation." Most of the other states in the United States have codes stating the law of pleading in civil actions, and such states are often described as code states to distinguish them from those adhering to the older forms of action, divided between those at law and those at equity. A few states have general codes of political and civil rights. The general drift of legislation and of public sentiment in the United States is towards the extension of the principle of codification, but the contrary view has been ably maintained (see J. C. Carter, _Provinces of the Written and the Unwritten Law_, New York, 1889).

Since the time of Bentham, the codification of the law of England has been the dream of the most enlightened jurists and statesmen. In the interval between Bentham and our own time there has been an immense advance in the scientific study of law, but it may be doubted whether the problem of codification is at all nearer solution. Interest has mainly been directed to the historical side of legal science, to the phenomena of the evolution of laws as part of the development of society, and from this point of view the question of remodelling the law is one of minor interest. To Bentham the problem presented itself in the simplest and most direct form possible. What he proposed to do was to set forth a body of laws, clearly expressed, arranged in the order of their logical connexion, exhibiting their own _rationale_ and excluding all other law. On the other hand the problem has in some respects become easier since the time of Bentham. With the Benthamite codification the conception of reform in the substantive law is more or less mixed up. If codification had been possible in his day, it would, unless it had been accompanied by the searching reforms which have been effected since, and mainly through his influence, perhaps have been more of an evil than a good. The mere dread that, under the guise of codification or improvement in form, some change in substance may secretly be effected has long been a practical obstacle in the way of legal reform. But the law has now been brought into a state of which it may be said that, if it is not the best in all respects that might be desired, it is at least in most respects as good as the conditions of legislation will permit it to be. Codification, in fact, may now be treated purely as a question of form. What is proposed is that the law, being, as we assume, in substance what the nation wishes it to be, should be made as accessible as possible, and as intelligible as possible. These two essential conditions of a sound system of law are, we need hardly say, far from being fulfilled in England. The law of the land is embodied in thousands of statutes and tens of thousands of reports. It is expressed in language which has never been fixed by a controlling authority, and which has swayed about with every change of time, place and circumstance. It has no definitions, no rational distinctions, no connexion of parts. Until the passing of the Judicature Act of 1873 it was pervaded throughout its entire sphere by the flagrant antinomy of law and equity, and that act has only ordered, not executed, its consolidation. No lawyer pretends to know more than a fragment of it. Few practical questions can be answered by a lawyer without a search into numberless acts of parliament and reported cases. To laymen, of course, the whole law is a sealed book. As there are no authoritative general principles, it happens that the few legal maxims known to the public, being apprehended out of relation to their authorities, are as often likely to be wrong as to be right. It is hopeless to think of making it possible for every man to be his own lawyer, but we can at least try to make it possible for a lawyer to know the whole law. The earlier advocates of codification founded their case mainly on the evils of judiciary law, _i.e._ the law contained in the reported decisions of the judges. Bentham's bitter antipathy to judicial legislation is well known. Austin's thirty-ninth lecture (_Lectures_, ed. 1869) contains an exhaustive criticism of the tenable objections to judiciary law. All such law is embedded in decisions on particular cases, from which it must be extracted by a tedious and difficult process of induction. Being created for particular cases it is necessarily uncomprehensive, imperfect, uncertain and bulky. These are evils which are incident to the nature of judiciary laws. The defective form of the existing statute law, moreover, has also given rise to loud complaints. Year by year the mass of legislation grows larger, and as long as the basis of a system is judiciary law, it is impossible that the new statutes can be completely integrated therewith. The mode of framing acts of parliament, and especially the practice of legislating by reference to previous acts, likewise produce much uncertainty and disorder. Some progress has, however, been made by the passing from time to time of various acts codifying branches of law, such as the Bills of Exchange Act 1882, the Partnership Act 1890, the Trusts Act 1893, and the Interpretation Act 1889.

The Statute Law Revision Committee also perform a useful work in excising dead law from the statute-book, partly by repeal of obsolete and spent acts and parts of acts, and partly by pruning redundant preambles and words. The construction of a section of an act may depend on the preamble and the context, and the repeal of the preamble and certain parts of the act may therefore affect the construction of what is left. This is provided for by a clause which is said to have been settled by Lord Westbury. It provides (in effect) that the repeal of any words or expressions of enactment shall not affect the construction of any statute or part of a statute. The lawyer, therefore, cannot rely on the revised edition of the statutes alone, and it is still necessary for him to consult the complete act as it was originally enacted.

The process of gradual codification adopted in India has been recommended for imitation in England by those who have had some experience of its working. The first of the Indian codes was the Penal Code (see CRIMINAL LAW), and there are also codes of civil and criminal procedure.

Whether any attempt will ever be made to supersede this vast and unarranged mass by a complete code seems very doubtful. Writers on codification have for the most part insisted that the work should be undertaken as a whole, and that the parts should have relation to some general scheme of the law which should be settled first. The practical difficulties in the way of an undertaking so stupendous as the codification _uno coëtu_ of the whole mass of the law hardly require to be stated.

In discussions on codification two difficulties are insisted on by its opponents, which have some practical interest--(1) What is to be done in those cases for which the code has not provided? and (2) How is new law to be incorporated with the code? The objection that a code will hamper the opinions of the court, destroy the flexibility and elasticity of the common law, &c., disappears when it is stated in the form of a proposition, that law codified will cover a smaller number of cases, or will be less easily adapted to new cases, than law uncodified. The French system ordered the judges, under a penalty, to give a decision on all cases, whether contemplated or not by the code, and referred them generally to the following sources:--(1) Équité naturelle, loi naturelle; (2) loi romain; (3) loi coutumier; (4) usages, exemples, jugements, jurisprudence; (5) droit commun; (6) principes généraux, maximes, doctrine, science. The Prussian code, on the other hand, required the judges to report new cases to the head of the judicial department, and they were decided by the legislative commission. No provision was made in either case for incorporating the new law with the code, an omission which Austin justly considers fatal to the usefulness of codification. It is absurd to suppose that any code can remain long without requiring substantial alteration. Cases will arise when its meaning must be extended and modified by judges, and every year will produce its quota of new legislation by the state. The courts should be left to interpret a code as they now interpret statutes, and provision should be made for the continual revision of the code, so that the new law created by judges or directly by the state may from time to time be worked into the code.

FOOTNOTE:

[1] The most ancient code known, that of Khammurabi, is dealt with in the article BABYLONIAN LAW.

CODE NAPOLÉON, the first code of the French civil law, known at first as the _Code civil des Français_, was promulgated in its entirety by a law of the 30th Ventose in the year XII. (31st of March 1804). On the 3rd of September 1807 it received the official name of Code Napoléon, although the part that Napoleon took in framing it was not very important. A law of 1818 restored to it its former name, but a decree of the 27th of March 1852 re-established the title of Code Napoléon. Since the 4th of September 1870 the laws have quoted it only under the name of the Code Civil.

Never has a work of legislation been more national in the exact sense of the word. Desired for centuries by the France of the _ancien régime_, and demanded by the _cahiers_ of 1789, this "code of civil laws common to the whole realm" was promised by the constitution of 1791. However, the two first assemblies of the Revolution were able to prepare only a few fragments of it. The preparation of a coherent plan began with the Convention. The _ancien régime_ had collected and adjusted some of the material. There was, on the one hand, a vast juridical literature which by eliminating differences of detail, had disengaged from the various French "customs" the essential part which they had in common, under the name of "common customary law"; on the other hand, the Roman law current in France had in like manner undergone a process of simplification in numerous works, the chief of which was that of Domat; while certain parts had already been codified in the _Grandes Ordonnances_, which were the work of d'Aguesseau. This legacy from the past, which it was desired to preserve within reason, had to be combined and blended with the laws of the Revolution, which had wrought radical reforms in the conditions affecting the individual, the tenure of real property, the order of inheritance and the system of mortgages. Cambacérès, as the representative of a commission of the Convention, brought forward two successive schemes for the Code Civil. As a member of one of the councils, he drew up a third under the Directory, and these projected forms came in turn nearer and nearer to what was to be the ultimate form of the code. So great was the interest centred in this work, that the law of the 19th Brumaire, year VIII., which, in ratification of the previous day's _coup d'état_ nominated provisional consuls and two legislative commissions, gave injunctions to the latter to draw up a scheme for the Code Civil. This was done in part by one of the members, Jacqueminot, and finally under the constitution of the year VIII., the completion of the work was taken in hand. The legislative machinery established by this constitution, defective as it was in other respects, was eminently suited for this task. Indeed, all projected laws emanated from the government and were prepared by the newly established council of state, which was so well recruited that it easily furnished qualified men, mostly veterans of the revolution, to prepare the final scheme. The council of state naturally possessed in its legislative section and its general assembly bodies both competent and sufficiently limited to discuss the texts efficiently. The _corps législatif_ had not the right of amendment, so could not disturb the harmony of the scheme. It was in the discussions of the general assembly of the council of state that Napoleon took part, in 97 cases out of 102 in the capacity of chairman, but, interesting as his observations occasionally are, he cannot be considered as a serious collaborator in this great work.

Those responsible for the scheme have in the main been very successful in their work; they have generally succeeded in fusing the two elements which they had to deal with, namely ancient French law, and that of the Revolution. The point in which their work is comparatively weak is the system of hypothec (q.v.), because they did not succeed in steering a middle course between two opposite systems, and the law of the 23rd of March 1855 (_sur la transcription en matière hypothécaire_) was necessary to make good the deficiency. A fault frequently found with the Code Civil is that its general divisions show a lack of logic and method, but the division is practically that of the Institutes of Justinian, and is about as good as any other: persons, things, inheritance, contracts and obligations, and finally, in place of actions, which have no importance for French law except from the point of view of procedure, privileges and hypothecs, as in the ancient _coutumes_ of France, and prescription. It is, _mutatis mutandis_, practically the same division as that of Blackstone's Commentaries.

Of late years other objections have been expressed; serious omissions have been pointed out in the Code; it has not given to personal property the importance which it has acquired in the course of the 19th century; it makes no provision for dealing with the legal relations between employers and employed which modern complex undertakings involve; it does not treat of life insurance, &c. But this only proves that it could not foretell the future, for most of these questions are concerned with economic phenomena and social relations which did not exist at the time when it was framed. The Code needed revising and completing, and this was carried out by degrees by means of numerous important laws. In 1904, after the celebration of the centenary of the Code Civil, an extra-parliamentary commission was nominated to prepare a revision of it, and at once began the work.

The influence of the Code Civil has been very great, not only in France but also abroad. Belgium has preserved it, and the Rhine provinces only ceased to be subject to it on the promulgation of the civil code of the German empire. Its ascendancy has been due chiefly to the clearness of its provisions, and to the spirit of equity and equality which inspires them. Numerous more recent codes have also taken it as a model: the Dutch code, the Italian, and the code of Portugal; and, more remotely, the Spanish code, and those of the Central and South American republics. In the present day it is rivalled by the German civil code, which, having been drawn up at the end of the 19th century, naturally does not show the same lacunae or omissions. It is inspired, however, by a very different spirit, and the French code does not suffer altogether by comparison with it either in substance or in form.

CODIAEUM, a small genus of plants belonging to the natural order Euphorbiaceae. One species, _C. variegatum_, a native of Polynesia, is cultivated in greenhouses, under the name of croton, for the sake of its leaves, which are generally variegated with yellow, and are often twisted or have the blades separated into distinct portions.

CODICIL (Lat. _codicillus_, a little book or tablet, diminutive of _codex_), a supplement to a will (q.v.), containing anything which a testator desires to add, or which he wishes to retract, to explain or to alter. In English law a codicil requires to be executed with the same formalities as a will under the Wills Act 1837.

CODILLA, the name given to the broken fibres which are separated from the flax during the scutching process. On this account it is sometimes termed scutching tow. Quantities of this material are used along with heckled tow in the production of tow yarns.

CODINUS, GEORGE [GEORGIOS KODINOS], the reputed author of three extant works in Byzantine literature. Their attribution to him is merely a matter of convenience, two of them being anonymous in the MSS. Of Codinus himself nothing is known; it is supposed that he lived towards the end of the 15th century. The works referred to are the following:--

1. _Patria_ ([Greek: Ta Patria tês Kônstantinoupoleôs]), treating of the history, topography, and monuments of Constantinople. It is divided into five sections: (_a_) the foundation of the city; (_b_) its situation, limits and topography; (_c_) its statues, works of art, and other notable sights; (_d_) its buildings; (_e_) the construction of the church of St Sophia. It was written in the reign of Basil II. (976-1025), revised and rearranged under Alexius I. Comnenus (1081-1118), and perhaps copied by Codinus, whose name it bears in some (later) MSS. The chief sources are: the _Patria_ of Hesychius Illustrius of Miletus, an anonymous (_c._ 750) brief chronological record ([Greek: Parastaseis syntomoi chronikai]), and an anonymous account ([Greek: diêgêsis]) of St Sophia (ed. T. Preger in _Scriptores originum Constantinopolitanarum_, fasc. i., 1901, to be followed by the _Patria_ of Codinus). Procopius, _De Aedificiis_ and the poem of Paulus Silentiarius on the dedication of St Sophia should be read in connexion with this subject.

2. _De Officiis_ ([Greek: Peri tôn Ophphikiôn]), a sketch, written in an unattractive style, of court and higher ecclesiastical dignities and of the ceremonies proper to different occasions. It should be compared with the _De Cerimoniis_ of Constantine Porphyrogenitus.

3. A chronological outline of events from the beginning of the world to the taking of Constantinople by the Turks (called Agarenes in the MS. title). It is of little value.

Complete editions are (by I. Bekker) in the Bonn _Corpus scriptorum Hist. Byz._ (1839-1843, where, however, some sections of the _Patria_ are omitted), and in J. P. Migne, _Patrologia graeca_, clvii.; see also C. Krumbacher, _Geschichte der byzantinischen Litteratur_ (1897).

COD-LIVER OIL (_Oleum Morrhuae_, or _Oleum Jecoris Aselli_), the oil obtained from the liver of the common cod (_Gadus morrhua_). In the early process for extracting the oil the livers were allowed to putrefy in wooden tubs, when oils of two qualities, one called "pale oil," and the other "light brown oil," successively rose to the surface and were drawn off. A third oil was obtained by heating the liver-residues to above the boiling-point of water, whereupon a black product, technically called "brown oil," separated. The modern practice consists in heating the perfectly fresh, cleaned livers by steam to a temperature above that of boiling water, or, in more recent practice, to a lower temperature, the livers being kept as far as possible from contact with air. The oils so obtained are termed "steamed-liver oils." The "pale" and "light brown" oils are used in pharmacy; the "brown" oil, the cod oil of commerce, being obtained from putrid and decomposing livers, has an objectionable taste and odour and is largely employed by tanners. By boiling the livers at a somewhat high temperature, "unracked" cod oil is obtained, containing a considerable quantity of "stearine"; this fat, which separates on cooling, is sold as "fish stearine" for soap-making, or as "fish-tallow" for currying. The oil when freed from the stearine is known as "racked oil." "Coast cod oil" is the commercial name for the oil obtained from the livers of various kinds of fish, _e.g._ hake, ling, haddock, &c. The most important centres of the cod-liver oil industry are Lofoten and Romsdal in Norway; the oil is also prepared in the United States, Canada, Newfoundland, Iceland and Russia; and at one time a considerable quantity was prepared in the Shetland Islands and along the east coast of Scotland.

Cod-liver oil contains palmitin, stearin and other more complex glycerides; the "stearine" mentioned above, however, contains very little palmitin and stearin. Several other acids have been identified: P. M. Meyerdahl obtained 4% of palmitic acid, 20% of jecoleic acid, C19H36O2, and 20% of therapic acid, C17H26O2; other investigators have recognized jecoric acid, C18H30O2, asellic acid, C17H32O2, and physetoleic acid, C16H30O2, but some uncertainty attends these last three acids. Therapic and jecoleic acids apparently do not occur elsewhere in the animal kingdom, and it is probable that the therapeutic properties of the oil are associated with the presence of these acids, and not with the small amount of iodine present as was at one time supposed. Other constituents are cholesterol (0.46-1.32%), traces of calcium, magnesium, sodium, chlorine and bromine, and various aliphatic amines which are really secondary products, being formed by the decomposition of the cellular tissue.

Cod-liver oil is used externally in medicine when its internal administration is rendered impossible by idiosyncrasy or the state of the patient's digestion. The oil is very readily absorbed from the skin and exerts all its therapeutic actions when thus exhibited. This method is often resorted to in the case of infants or young children suffering from abdominal or other forms of tuberculosis. Its only objection is the odour which the patient exhales. When taken by the mouth, cod-liver oil shares with other liver-oils the property of ready absorption. It often causes unpleasant symptoms, which must always be dealt with and not disregarded, more harm than good being done if this course is not followed. Fortunately a tolerance is soon established in the majority of cases. It has been experimentally proved that this is more readily absorbed than any other oil--including other liver-oils. Much attention has been paid to the explanation of this fact, since knowledge on this point might enable an artificial product, without the disadvantages of this oil, to be substituted for it. Very good results have been obtained from a preparation named "lipanin," which consists of six parts of oleic acid and ninety-four of pure olein. Cod-liver oil has the further peculiarity of being more readily oxidizable than any other oil; an obviously valuable property when it is remembered that the entire food-value of oils depends on their oxidation.

Cod-liver oil may be given in all wasting diseases, and is occasionally valuable in cases of chronic rheumatoid arthritis; but its great therapeutic value is in cases of tuberculosis of whatever kind, and notably in pulmonary tuberculosis or consumption. Its reputation in this is quite inexpugnable. It is essential to remember that "in phthisis the key of the situation is the state of the alimentary tract," and the utmost care must be taken to obviate the nausea, loss of appetite and diarrhoea, only too easily induced by this oil. It is best to begin with only one dose in the twenty-four hours, to be taken just before going to sleep, so that the patient is saved its unpleasant "repetition" from an unaccustomed stomach. In general, it is therefore wise to order a double dose at bedtime. The oil may be given in capsules, or in the form of an emulsion, with or without malt-extract, or success may be obtained by adding, to every two drachms of the oil, ten minims of pure ether and a drop of peppermint oil. The usual dose, at starting, is one or two drachms, but the oil should be given eventually in the largest quantities that the patient can tolerate.

CODRINGTON, CHRISTOPHER (1668-1710), British soldier and colonial governor, whose father was captain-general of the Leeward Isles, was born in the island of Barbados, West Indies, in 1668. Educated at Christ Church, Oxford, he was elected a fellow of All Souls, and subsequently served with the British forces in Flanders, being rewarded in 1695 with a captaincy in the Guards. In the same year he attended King William III. on his visit to Oxford, and, in the absence of the public orator, was chosen to deliver the University oration. In 1697, on the death of his father, he was appointed captain-general and commander-in-chief of the Leeward Isles. In 1703 he commanded the unsuccessful British expedition against Guadeloupe. After this he resigned his governorship, and spent the rest of his life in retirement and study on his Barbados estates. He died on the 7th of April 1710, bequeathing these estates to the Society for the Propagation of the Gospel in Foreign Parts for the foundation of a college in Barbados. This college, known as the Codrington college, was built in 1714-1742. To All Souls College, Oxford, he bequeathed books worth £6000 and £10,000 in money, out of which was built and endowed the Codrington library there.

CODRINGTON, SIR EDWARD (1770-1851), British admiral, belonged to a family long settled at Dodington in Gloucestershire. He was the youngest of three brothers, who were left orphans at an early age, and were educated by an uncle, Mr Bethell. Edward Codrington was sent for a short time to Harrow, and entered the navy in July 1783. He served on the American station, in the Mediterranean and at home, till he was promoted lieutenant on the 28th of May 1783. Lord Howe selected him to be signal lieutenant on the flagship of the Channel fleet at the beginning of the revolutionary war with France. In that capacity he served in the "Queen Charlotte" (100) during the operations which culminated in the battle of the 1st of June 1794. The notes he wrote on Barrow's account of the battle in his _Life of Howe_, and the reminiscences he dictated to his daughter, which are to be found in her memoir of him, are of great value for the history of the action. On the 7th of October 1794 he was promoted commander, and on the 6th of April 1795 attained the rank of post-captain and the command of the "Babet" (22). He continued to serve in the Channel, and was present at the action off L'Orient on the 23rd of June 1795. Codrington wrote notes on this encounter also, which are to be found in the memoir. They are able and valuable, but, like all his correspondence throughout his life, show that he was of a somewhat censorious disposition, was apt to take the worst view of the conduct of others, and was liable to be querulous. He next commanded the "Druid" (32) in the Channel and on the coast of Portugal, till she was paid off in 1797. Codrington now remained on shore and on half-pay for some years. In December 1802 he married Jane, daughter of Jasper Hall of Kingston, Jamaica.

On the renewal of the war after the breach of the peace of Amiens he was appointed (May 1805) to the command of the "Orion" (74) and was attached to the fleet on the coast of Spain, then blockading Villeneuve in Cadiz. The "Orion" took a conspicuous part in the battle of Trafalgar. Codrington's correspondence contains much illuminative evidence as to the preliminaries and the events of the victory. From 1805 till 1813 he continued to serve first in the "Orion" and then (1808) in the "Blake" (74) in European waters. He was present on the Walcheren expedition, and was very actively employed on the Mediterranean coast of Spain in co-operating with the Spaniards against the French. In 1814 he was promoted rear-admiral, at which time he was serving on the coast of North America as captain of the fleet to Sir Alexander Cochrane during the operations against Washington, Baltimore and New Orleans. In 1815 he was made K.C.B., and was promoted vice-admiral on the 10th of July 1821. In December 1826 he was appointed to the Mediterranean command, and sailed on the 1st of February 1827. From that date until his recall on the 21st of June 1828 he was engaged in the arduous duties imposed on him by the Greek War of Independence, which had led to anarchy and much piracy in the Levant. On the 20th of October 1827 he destroyed the Turkish and Egyptian naval forces at Navarino (q.v.), while in command of a combined British, French and Russian fleet. As the battle had been unforeseen in England, and its result was unwelcome to the ministry of the day, Codrington was entangled in a correspondence to prove that he had not gone beyond his instructions, and he was recalled by a despatch, dated the 4th of June.

After the battle Codrington went to Malta to refit his ships. He remained there till May 1828, when he sailed to join his French and Russian colleagues on the coast of the Morea. They endeavoured to enforce the evacuation of the peninsula by Ibrahim peacefully. The Pasha made diplomatic difficulties, and on the 25th of July the three admirals agreed that Codrington should go to Alexandria to obtain Ibrahim's recall by his father Mehemet Ali. Codrington had heard on the 22nd of June of his own supersession, but, as his successor had not arrived, he carried out the arrangement made on the 25th of July, and his presence at Alexandria led to the treaty of the 6th of August 1828, by which the evacuation of the Morea was settled. His services were recognized by the grant of the grand cross of the Bath, but there is no doubt that he was treated as a scape-goat at least to some extent. After his return home he was occupied for a time in defending himself, and then in leisure abroad. He commanded a training squadron in the Channel in 1831 and became admiral on the 10th of January 1837. From November 1839 to December 1842 he was commander-in-chief at Portsmouth. He died on the 28th of April 1851.

Sir Edward Codrington left two sons, Sir William (1804-1884), a soldier who commanded in the Crimea, and Sir John Henry (1808-1877), a naval officer, who died an admiral of the fleet.

See _Memoir of the Life of Admiral Sir Edward Codrington_, by his daughter Jane, Lady Bourchier, wife of Sir T. Bourchier, R.N. (London, 1873). (D. H.)

CODRUS, in Greek legend, the last king of Athens. According to the story, it was prophesied at the time of the Dorian invasion of Peloponnesus (_c._ 1068 B.C.) that only the death of their king at the enemy's hands could ensure victory to the Athenians. Devoting himself to his country, Codrus, in the disguise of a peasant, made his way into the enemy's camp, and provoked a quarrel with some Dorian soldiers. He fell, and the Dorians, on discovering that Codrus had been slain, retreated homeward, despairing of success. No one being thought worthy to succeed Codrus, the title of king was abolished, and that of archon (q.v.) substituted for it.

CODY, WILLIAM FREDERICK (1846- ), American scout and showman, known under the name of "Buffalo Bill," was born in 1846 in Scott county, Iowa. He first became known as one of the riders of the "Pony Express," a mail service established in the spring of 1860 by the Central Overland California and Pike's Peak Express Company to carry the mails overland from Saint Joseph, Missouri, to Sacramento, California, a distance of 1950 m., by means of relays of ponies, each rider being expected to cover about 75 m. daily. Owing to the wildness of the country and the hostility of the Indians, both the riders and the station-keepers led lives of great hardship and danger. The "Pony Express" was discontinued in 1861 upon the completion of the Pacific Telegraph company's line, and young Cody became a scout and guide for the United States army. In 1863 he formally enlisted in the 7th regiment of Kansas cavalry, in which he served until the close of the Civil War. In 1867 he made a contract with the Kansas Pacific railway to furnish its employees with buffalo meat while the line was being extended through the wilderness, and his name of "Buffalo Bill" was given him from this circumstance. In 1868-1872 he was again an army scout and guide, serving against the Sioux and Cheyennes; and in 1872 was a member of the Nebraska house of representatives. During the Sioux-Cheyenne War of 1876 he served in the 5th United States Cavalry, and at the battle of Indian Creek killed the Cheyenne chief Yellow Hand in single combat. In 1883 he organized his "Wild West Show," a spectacular performance on a large scale, his first European tour taking place in 1887. In the Nebraska national guard he again served against the Sioux in 1890-1891.

CO-EDUCATION, the term applied to the instruction and training of boys and girls, or of young people of both sexes, in the same school or institution, in the same classes and through the same courses of study. Examples of the thoroughgoing application of this principle can be found in every grade of education from the elementary school to the university. But the term "Co-education" is sometimes used in a wider sense, in order to include cases in which boys and girls, or young men and young women of university age, are admitted to membership of the same school or college but receive instruction wholly or in part in separate classes and in different subjects. Other variable factors in co-educational systems are the extent to which men and women are mixed on the teaching staff, and the freedom of intercourse permitted between pupils of the two sexes in class, in games and in other activities of school life. In another form of combined education (preferred by Comte, _Système de politique positive_, iv. 266), pupils of the two sexes are taught successively by the same teacher. By the English Board of Education, a distinction is drawn between mixed schools and dual schools. "Mixed schools" are those in which, for most subjects of the curriculum, boys and girls are taught together by the same teachers: in "dual schools" there are separate boys' and girls' departments under a single principal, but with separate entrances, classrooms and playgrounds for the two sexes.

_History._--Co-education in early times was occasional and sporadic. For example, women were admitted by Plato to the inner circle of the Academy on terms of equality with men. The educational endowments of Teos provided that the professors of literature should teach both boys and girls. It is uncertain whether the Roman schools in classical times were attended by both sexes. A tombstone found at Capua represents a schoolmaster with a boy on one side and a girl on the other. Probably co-education was practised in country districts for economical reasons; and also in the home schools organized by wealthier families (Wilkins, _Roman Education_, pp. 42-43). At Charles the Great's Palace School at Aachen (A.D. 782 onwards), Alcuin taught together the young princes and their sisters, as well as grown men and women. The Humanists of the Renaissance made the full development of personality a chief aim of education, and held up literary accomplishment as a desirable mark of personal distinction both for men and women. This led to the scholarly education of girls along with boys in the home schools of some great families. Thus, at Mantua (1423 onwards), Vittorino da Feltre taught Cecilia Gonzaga with her brothers and the other boy pupils at his boarding-school; but there is no evidence that the latter was otherwise co-educational. Luther and other Reformers urged that girls as well as boys should be taught to read the Bible. Hence came the tendency to co-education of boys and girls in some elementary schools in Protestant lands. This tendency can be traced both in Scotland and in the northern parts of England. It is believed that, in the early days of New England, district schools in smaller American towns were open to boys and girls alike, but that few girls advanced beyond reading and writing (Martin, _Massachusetts Public School System_, p. 130). At Dorchester, Mass., it was left to the discretion of the elders and schoolmen whether maids should be taught with the boys or not; but in practice the girls seem to have been educated apart. In 1602 the council of Ayr, Scotland, ordained that the girls who were learning to read and write at the Grammar School should be sent to the master of the Song School, "because it is not seemly that sic lasses should be among the lads" (Grant, _History of the Burgh and Parish Schools of Scotland_, p. 526 ff.). Meriden, Connecticut, seems to have made common provision for the elementary education of boys and girls in 1678. Northampton, Mass., did the same in 1680. Deerfield, Mass., in 1698 voted that "all families having children either male or female between the ages of six and ten years shall pay by the poll for their schooling"--presumably in the common school.

Thus the beginnings of co-education in its modern organized form may be traced back partly to Scotland and partly to the United States. The co-education of boys and girls, carried through in varying degrees of completeness, was not uncommon in the old Endowed Schools of Scotland, and became more frequent as increasing attention was given to the education of girls. At the Dollar Institution, founded by John McNabb for the benefit of the poor of the parish of Dollar and shire of Clackmannan (date of will, 1800), boys and girls have been educated together in certain classes since the beginning of the school in 1818. In the eastern parts of the United States, where the Puritan tradition also prevailed, co-education struck firm root, and spread chiefly for reasons of convenience and economy (Dexter, _History of Education in United States_, p. 430). But throughout the west, co-education was strongly preferred in elementary and secondary schools and in universities on the further ground that it was believed to be more in accordance with the democratic principle of equal educational opportunity for the two sexes.

It should be added, however, that the leaven of Pestalozzi's thought has worked powerfully both in Europe and America in favour of the idea of co-education. His view was that all educational institutions should, as far as possible, be modelled upon the analogy of the family and of the home. At Stanz (1798-1799) he educated together in one household boys and girls ranging in age from five to fifteen. At Burgdorf (1799-1804) his work was in part co-educational. At Yverdun (1804-1825) Pestalozzi established a school for girls close to his school for boys. The girls received instruction from some of the masters of the boys' school, and girls and boys met at evening worship, in short excursions and at other times.

In England, the Society of Friends have been the pioneers of co-education in boarding schools, both for younger children and for pupils up to fifteen or sixteen years of age. The practice of the society, though not exclusively co-educational, has long been favourable to co-education, either in its complete or restricted form, as being more in harmony with the conditions of family life. Ackworth school was established by the London Yearly Meeting in 1779 for the education of boys and girls; but the school has never been fully co-educational, the boys and girls being taught separately except in a few classes. At Sidcot school, which was founded in 1808 by the Associated Quarterly Meetings in the west of England for the education of children of Friends, boys and girls are taught together, except in certain handicraft subjects. Several other co-educational schools were founded by the Society of Friends during the first half of the 19th century.

Since that time the movement towards co-education in secondary schools and universities has steadily gained strength in England. It has been furthered by the diffusion of Pestalozzian ideas and also by the influence of American example. In England, private schools have made some of the most valuable co-educational experiments. A private boarding and day secondary school on co-educational lines was instituted by Mr W. A. Case in Hampstead in 1865. A co-educational boarding-school was founded in 1869 by Miss Lushington at Kingsley near Alton, Hants. In 1873 Mr W. H. Herford began the Ladybarn school for boys and girls at Withington in the suburbs of Manchester. The passing of the Welsh Intermediate Education Act 1889 led to the establishment of a considerable number of new mixed or dual secondary day-schools in Wales. Many English teachers gained experience in these schools and subsequently influenced English education. The work and writings of Mr J. H. Badley at Bedales, Petersfield, a co-educational boarding-school of the first grade, gave greatly increased weight to the principle of co-education. Important additions have also been made to the fund of co-educational experience by the King Alfred's school (Hampstead), Keswick school, and West Heath school (Hampstead). In 1907 a Public Co-educational Boarding School was opened at Harpenden.

Since the Education Act 1902 became law, there has been a rapid increase of co-educational secondary day-schools of the lower grade, under county or borough education authorities, in all parts of England. This increase is due to two chief causes, viz. (1) The co-educational tradition of some of the higher grade board schools, many of which have become secondary schools; and (2) the economy effected by establishing one co-educational secondary school, in place of two smaller schools for boys and girls separately.

The idea of co-education in secondary schools has spread in several other European countries, especially in Holland, Norway, Sweden and Denmark. In Scandinavia, the new practice appears to have begun with the establishment of a private higher secondary school, the Palmgremska Samskolan, in Stockholm, in 1876. A similar school, Nya Svenska Läroverket, was founded upon the same model in Helsingfors, Finland, in 1880. In Norway, the law of 1896 introduced co-education in all state schools. In Denmark, as in Norway, co-education was begun in private schools; on its proving a success there, it was introduced into the state schools, with two exceptions; and it is now obligatory in most state schools but optional in private schools (J. S. Thornton, _Schools Public and Private in the North of Europe_, 1907, p. 97). In Holland, there is now a good deal of co-education in lower secondary schools of the modern type. For example, at Utrecht, the state higher burgher school provides the same course of instruction, except in gymnastics, for boys and girls. At Almeloo, the municipal higher burgher school, though co-educational, differentiates the classes in several subjects. In Belgium, France, Germany and Austria, co-education, though frequent in elementary schools, is regarded as undesirable in secondary; but the movement in its favour in many parts of Germany seems to be gathering strength. All over Europe the Roman Catholic populations prefer the older ideal of separate schools for boys and girls.

Co-education in colleges and universities, which began at Oberlin, Ohio, in 1833, was adopted almost without exception by the state universities throughout the west of America from 1862 onwards. Since that time the idea has spread rapidly throughout Europe, and the presence of women students at universities originally confined to men is one of the most striking educational facts of the age.

_Co-education in the United Kingdom, (a) England and Wales._--The Board of Education does not possess any summary showing the number of pupils in mixed public elementary schools or in mixed departments of such schools. In 1901, out of 31,502 departments of public elementary schools in England and Wales, nearly half (15,504) were mixed departments, in which boys and girls were educated together. But as the departments were of unequal size, it must not be inferred from this that half the children in public elementary schools in that year (5,883,762) were receiving co-education. Of the total number of departments in public elementary schools in England and Wales, the percentage of mixed schools fell from 51.6 in 1881 to 49.4 in 1891 and 49.2 in 1901. But these percentages must not be taken to prove an absolute decline in the number of children in mixed departments.

In England, out of 492 public secondary schools which were recognized by the Board of Education for the receipt of government grant for the school year ending July 31, 1905, and which contained 85,358 pupils, 108 schools, with 21,720 pupils, were mixed; and 20 schools, with 8980 pupils, were dual schools.

Thus, of the total number of pupils in the secondary schools referred to above, a little over 25% were in mixed schools, and about 10% were in dual schools. It is not safe to assume, however, that all the mixed schools were completely co-educational in their work, or that the dual schools were not co-educational in respect of certain subjects or parts of the course. It should also be remembered that, besides the secondary schools recognized by the Board of Education for the receipt of government grant, there is a considerable number of great endowed secondary boarding-schools ("public schools" in the English use of that expression) which are for boys only. There are also at least 5000 private secondary schools, of which, in 1897 (since when no comprehensive statistical inquiry has been made), 970, with 26,027 pupils, were mixed schools. But the great majority of the children in these mixed schools were under twelve years of age. The number of boys and girls over twelve years of age, in the mixed private secondary schools which were included in the 1897 return, was only 5488.

In Wales, for the school year ending July 31, 1905, out of 84 state-aided public secondary schools, 11 were mixed and 44 were dual schools. The number of scholars in the Welsh schools referred to above was 9340. Of these, 1457, or 15%, were in mixed schools, and 5085, or 54%, were in dual schools. The managers of dual schools in Wales have the power to arrange that boys and girls shall be taught together in any or all the classes; and, as a matter of fact, nearly all the dual schools are worked as mixed schools, though they appear in these figures under dual.

_(b) Scotland._--In the public elementary schools, including the higher grade schools of Scotland, co-education is the almost universal rule. The exceptions, which for the most part are Roman Catholic or Episcopal Church schools, tend to diminish year by year. In 1905, out of 3843 departments in the Scotch public elementary and higher grade schools, 3783 were mixed. These include the infant departments. Out of the total number of children in the public elementary and higher grade schools, including infants' departments, 98.43% were receiving co-education.

In the secondary schools of Scotland there has been in recent years little perceptible movement either towards co-education or away from it. What movement there is, favours the establishment of separate secondary schools for girls in the large centres of population. Out of 109 public secondary schools in Scotland in 1905-1906, 29 schools were for boys only and 40 schools for girls only. One school had boys and girls in separate departments. In the remaining 39 schools, boys and girls were taken together to an extent which varied with the subjects taken; but there was nothing of the nature of a strict separation of the sexes as regards the ordinary work of the school.

_(c) Ireland._--In Ireland, the percentage of pupils on the rolls of mixed national schools (_i.e._ schools attended by boys and girls), to the total number of pupils on the rolls of all national schools, has slowly increased. In 1880 the percentage was 57.5; in 1898, 59.4; in 1905, 60.9.

The Commissioners of Intermediate Education in Ireland had on their list in 1906, 38 secondary schools which were classified by them as mixed schools. These schools were attended by 640 boys and 413 girls between 13 and 19 years of age. The commissioners do not know to what extent the boys and girls in these schools received instruction in the same classes. As, however, the schools are small, they believe that in the great majority of cases the boys and girls were taught together. In one large school not classified as mixed, the boys (117) and girls (60) were taught in the same classes.

_Universities and University Colleges in the United Kingdom._--Women are admitted as members of the universities of London, Durham, Manchester, Liverpool, Birmingham, Leeds, Sheffield, Wales, Edinburgh, Aberdeen, St Andrews, Glasgow, Dublin and the Royal University of Ireland. At Oxford and Cambridge women are not admitted as members of the university, but by courtesy enjoy entrance to practically all university lectures and examinations. The social life of the men and women students is more separate in the old than in the new universities. In no grade of education in the United Kingdom has the principle of co-education made more rapid advance than in the universities. The university education of women began in London (Queen's College 1848, Bedford College 1849, both being preceded by classes in earlier years). The University of London in 1878 decided to accept from the crown a supplemental charter making every degree, honour and prize awarded by the university accessible to students of both sexes on perfectly equal terms. By charter in 1880, the Victoria University (now broken up into the universities of Manchester, Liverpool and Leeds) received power to grant degrees to women as well as to men. The charter of the university of Wales (1893) provides that "Women shall be eligible equally with men for admittance to any degree which our university is authorized to confer; every office created in the university, and the membership of every authority constituted by the charter shall be open to women equally with men." In 1889 the Universities (Scotland) Act empowered the commissioners to make ordinances, enabling each university to admit women in graduation in one or more faculties and to provide for their instruction. At all the university colleges in the United Kingdom women are educated as well as men.

_United States._--Co-education is a characteristic feature of the educational system of the different states of the American Union. Of elementary school pupils at least 96%, and of secondary school pupils 95%, are in mixed schools. In 1903, out of a total enrolment of 15,990,803 pupils in public elementary and secondary schools and training colleges, 15,387,734 were in schools attended by pupils of both sexes. Out of 550,600 pupils on the rolls of public secondary schools (high schools) in 1902, 523,300 were in co-educational schools. The same was true of 43% of the pupils (numbering over 100,000) in private secondary schools. In colleges and universities 62% of all undergraduates were in co-educational institutions, to which category thirty-four American universities belong (U.S. Commissioner of Education, _Report for 1903_, p. 2454). In America opinion is thus predominantly in favour of co-education, but there is a current of adverse criticism, especially among some who have had experience of school conditions in large cities.

_General Review of the Question._--In schools for infants and younger children co-education is approved by all authorities. It is increasingly favoured on educational grounds in smaller schools for children up to 12 or 13 years of age or thereabouts. But where elementary schools have to be large, separate departments for boys and girls are generally preferable, though mixed schools are often established for reasons of economy. At the other end of the educational scale, viz. in the universities, the co-education of men and women in the same institution is fast becoming the rule. This is due partly to the prohibitive cost of duplicating teaching staff, laboratories, libraries and other equipment, partly to the desire of women to qualify themselves for professional life by passing through the same courses of training as are prescribed for men. The degree, however, to which social intercourse is carried on between men and women students differs widely in the different co-educational universities. There are occasional signs, _e.g._ at Chicago, of a reaction against the fullest form of academic co-education. And it is probable that the universities will provide, among many courses common to men and women, some (like engineering) suitable for men only, and others (like advanced instruction in home-science, or certain courses of professional preparation for teachers of young children) which will rarely be attended by any but women. Common use of the same university institutions is compatible with much differentiation in courses of study and with separately organized forms of collegiate life. It is with regard to the part of education which lies between the elementary schools and the universities that the sharpest division of opinion upon the principle of co-education now exists. In Europe, with the exception of Scandinavia, those who advocate co-education of the sexes in secondary schools up to 18 or 19 years of age are at present in a distinct minority, even as regards day schools, and still more when they propose to apply the same principle to boarding schools. But the application of the co-educational principle to all schools alike is favoured by an apparently increasing number of men and women. This movement in opinion is connected with the increase in the number of girls desiring access to secondary schools, a demand which can most easily and economically be met by granting to girls access to some of the existing schools for boys. The co-educational movement is also connected with a strong view of sex equality. It is furthered by the rapidly increasing number of women teachers who are available for higher educational work. Mixed secondary schools with mixed staffs are spreading for reasons of economy in smaller towns and rural districts. In large towns separate schools are usually recommended in preference, but much depends upon the social tradition of the neighbourhood. Those who advocate co-education for boys and girls in secondary schools urge it mainly on the ground of its naturalness and closer conformity to the conditions of healthy, unselfconscious home life. They believe it to be a protective against uncleanness of talk and school immorality. They point to its convenience and economy. They welcome co-education as likely to bring with it a healthy radicalism in regard to the older tradition of studies in boys' secondary schools. They approve it as leading to mixed staffs of men and women teachers, and as the most effectual way of putting girls in a position of reasonable equality with boys in respect of intellectual and civic opportunity. On the other hand, those who oppose co-education in secondary schools rest their case upon the danger of the intellectual or physical overstrain of girls during adolescence; and upon the unequal rate of development of boys and girls during the secondary school period, the girls being more forward than the boys at first, but as a rule less able to work as hard at a somewhat later stage. The critics further complain that co-education is generally so organized that the girls' course of study is more or less assimilated to that of the boys, with the result that it cannot have the artistic and domestic character which is suitable for the majority of girls. Complaint is also made that the head of a co-educational school for pupils over the age of 10 is usually a man, though the health and character of girls need the care and control of a woman vested with complete authority and responsibility. While demurring to the view that co-education of the sexes would be a moral panacea, the critics of the system admit that the presence of the girls would exert a refining influence, but they believe that on the whole the boys are likely to gain less from co-education than the girls are likely to lose by it. In all these matters carefully recorded observation and experiment are needed, and it may well be found that co-education is best for some boys and for some girls, though not for all. Temperaments and dispositions differ. Some boys seem by nature more fitted for the kind of training generally given to girls; some girls are by nature fitted for the kind of training generally given to boys. The sex division does not mark off temperaments into two sharply contrasted groups. The introduction of girls into boys' secondary schools may remove or mitigate coarse traditions of speech and conduct where such persist. But it would be unfortunate if stiff and pedantic traditions of secondary education were now fixed upon girls instead of being reconsidered and modified in the interests of boys also. In any case, if co-education in secondary schools is to yield the benefits which some anticipate from it, great vigilance, careful selection of pupils and very liberal staffing will be necessary. Without these securities the results of co-education in secondary schools might be disappointing, disquieting or even disastrous.

BIBLIOGRAPHY.--Plato in the _Republic_ (v. 452-456) and _Laws_ (vii. 804-805) argues that women should share as far as possible in education with men. Mary Wollstonecraft, _A Vindication of the Rights of Women_ (1792), contends that "both sexes ought, not only in private families but in public schools, to be educated together." J. G. Spurzheim, _Principles of Education_, pp. 272-288 (Edinburgh, 1821), replies to this argument. In the Board of Education _Special Reports on Educational Subjects_, vol. vi. (Wyman & Sons, 1900), J. H. Badley, writing on _The Possibility of Co-education in English Preparatory and other Secondary Schools_, is strongly in favour. "In co-education ... half-heartedness means failure. The more completely both sexes can be brought together upon an equal and natural footing the less the difficulties grow." In the Board of Education _Special Reports_, vol. xi. (Wyman & Sons, 1902), Rev. Cecil Grant, writing on _Can American Education be grafted upon the English Public School System?_ answers strongly in the affirmative; co-education is recommended on eight grounds:--(1) Vast economy of expenditure; (2) return to the natural system; (3) discipline made easier; (4) intellectual stimulus; (5) a better balance in instruction; (6) improved manners; (7) prevention of extremes of masculinity or femininity; (8) a safeguard against the moral danger.

_Co-education: a series of Essays_ (London, 1903), edited by Alice Woods, is in favour of co-education, nine practical workers recording their experience; this is one of the best books on the subject. J. H. Badley's _Co-education after Fifteen: its Value and Difficulties_. _Child Life_ (London, January, 1906), is candid, judicious and practical. M. E. Sadler in _Reports on Secondary Education in Hampshire, Derbyshire and Essex_ (1904, 1905 and 1906 respectively) gives details of the curriculum of many co-educational secondary schools. In the U.S. Commissioner of Education _Report for 1903_, vol. i. pp. 1047-1078, Anna Tolman Smith, writing on _Co-education in the Schools and Colleges of the United States_, gives an historical review of the subject with bibliography (compare bibliography in _Report of U.S. Commissioner of Education for 1900-1901_, pp. 1310-1325). G. Stanley Hall on _Adolescence, its Psychology and its Relations to Physiology, Anthropology, Sociology, Sex, Crime, Religion and Education_, vol. ii. chap. xvii., on Adolescent Girls and their education (New York, D. Appleton & Co., 1904), is strongly against co-education during adolescence. In W. Rein's _Encyklopädisches Handbuch der Pädagogik_ (Langensalza, Beyer), art. "Gemeinsame Erziehung für Knaben und Mädchen," K. E. Palmgren is in favour of co-education (vol. iii. of 2nd ed. 1905). See also W. Rein, _Über gemeinsame Erziehung von Knaben und Mädchen_ (Freiburg, 1903), and _Bericht über den I. Internationalen Kongress für Schulhygiene_ (Nürnberg, 1904), vol. ii. pp. 140 ff., "Co-education in der höheren Schulen." (M. E. S.)

COEFFETEAU, NICOLAS (1574-1623), French theologian, poet and historian, was born at Saint-Calais. He entered the Dominican order and lectured on philosophy at Paris, being also "ordinary preacher" to Henry IV., and afterwards ambassador at Rome. In 1606 he was vicar-general of the congregation of France, and received from Marie de' Medici the revenues of the sees of Lombez and Saintes. He also administered the diocese of Metz, and was nominated to that of Marseilles in 1621, but ill-health obliged him here to take a coadjutor. Coeffeteau won considerable distinction in the controversy against the Protestant reformers and also wrote a _History of Rome from Augustus to Constantine_. Many of his theological writings were collected in one volume (Paris, 1622), and at the time of his death in 1623 he was engaged on a translation of the New Testament which is still in manuscript.

COEHOORN, MENNO, BARON VAN (1641-1704), Dutch soldier and military engineer, of Swedish extraction, was born at Leeuwarden in Friesland. He received an excellent military and general education, and at the age of sixteen became a captain in the Dutch army. He took part in the defence of Maastricht in 1673 and in the siege of Grave in the same year, where the small mortars (called coehorns) invented by him caused the French garrison considerable trouble (Seydel, _Nachrichten über Festungskriege_, Leipzig, 1818). He was made a colonel for his gallant conduct at the battle of Seneff (1674), and was present also at the battles of Cassel (1677) and Saint Denis (1678).

The circumstances of the time and the country turned Coehoorn's attention to the art of fortification, and the events of the late war showed him that existing methods could no longer be relied upon. His first published work, _Versterckinge de Vijfhoeks met alle syne Buytenwerken_ (Leeuwarden, 1682), at once aroused attention, and involved the author in a lively controversy with a rival engineer, Louys Paan (Leeuwarden, 1682, 1683; copies are in the library of the Dutch ministry of war). The military authorities were much interested in this, and entrusted Coehoorn with the reconstruction of several fortresses in the Netherlands. This task he continued throughout his career; and his experience in the work made him the worthy rival of his great contemporary Vauban. He formulated his ideas a little later in his chief work, _Nieuwe Vestingbouw op en natte of lage horizont_, &c. (Leeuwarden, 1685), in which he laid down three "systems," the characteristic feature of which was the multiplicity and great saliency of the works, which were calculated and in principle are still eminently suited for flat and almost marshy sites such as those of the Low Countries. He borrowed many of the details from the works of his Dutch predecessor Freytag, of Albrecht Dürer, and of the German engineer Speckle, and in general he aimed rather at the adaptation of his principles to the requirements of individual sites than at producing a geometrically and theoretically perfect fortress; and throughout his career he never hesitated to depart from his own rules in dealing with exceptional cases, such as that of Groningen. Subsequent editions of _Nieuwe Vestingbouw_ appeared in Dutch (1702, and frequently afterwards), English (London, 1705), French (Wesel, 1705), and German (Düsseldorf, 1709).

From 1688 to the treaty of Ryswick Coehoorn served as a brigadier. At the battle of Fleurus he greatly distinguished himself, and in 1692 he defended Namur, a fortress of his own creation. Namur was taken by Vauban; but the Dutch engineer had his revenge three years later, when the place, on which in the meantime Vauban had lavished his skill, fell to his attack. Coehoorn became lieutenant-general and inspector-general of the Netherlands fortresses, and the high-German peoples as well as his own countrymen honoured him. He commanded a corps in the army of the duke of Marlborough from 1701 to 1703, and in the constant siege warfare of these campaigns in the Low Countries his technical skill was of the highest value. The swift reduction of the fortress of Bonn and the siege of Huy in 1703 were his crowning successes. At the opening of his following campaign he was on his way to confer with Marlborough when he died of apoplexy at Wijkel on the 17th of March 1704.

His "first system" was applied to numerous places in Holland, notably Nijmwegen, Breda and Bergen-op-Zoom. Mannheim in Germany was also fortified in this way, while the "secondsystem" was applied to Belgrade and Temesvár in eastern Europe.

His son, Gosewijn Theodor van Coehoorn, wrote his life (re-edited Syperstein, Leeuwarden, 1860). See also v. Zastrow, _Geschichte der beständigen Befestigung_ (Leipzig, 1828); von Brese-Winiari, _Über Entstehen und Wesen der neueren Befestigungsmethode_ (1844); Cosseran de Villenoisy, _Essai historique sur la fortification_ (1869); Mandar, _Architecture des forteresses_ (1801); Krayenhoff, _Verhandeling over de erste versterkingsmanier van Coehoorn_ (Hague, 1823); Bosscha, _Nederlandsche heldend te Land_ (Amsterdam, 1838); Dewez, _Histoire de Belgique_ (Brussels, 1823); Ypey, _Narratio de rebus gestis Mennonis Cohorni_ (1771); Hennert, _Dissertation sur la fortification permanente_ (1795); Böhms, _Gründliche Anleitung zur Kriegsbaukunst_ (1776); _Axiomatas of allgemeene bekentnisse over de Vestinghbouw door Menno Baron van Coehoorn, Uytgewerkt door E.

COELENTERA, a group or grade of the animal kingdom, the zoological importance of which has risen considerably since the time (1887) of the publication of the first article under that heading in the _Ency. Brit._ (9th edit.), even though their numbers have been reduced by the elevation of the Sponges or Porifera to the rank of an independent Phylum under the title Parazoa (W. J. Sollas, 1884). For the Coelentera thus restricted, the term Enterocoela, in contrast to Coelomocoela (the old Coelomata), was suggested by E. R. Lankester (1900).

From the more complex colonial Protozoa the Coelentera are readily separated by their possession of two distinct sets of cells, with diverse functions, arranged in two definite layers,--a condition found in no Protozoan. The old criterion by which they and other Metazoa were once distinguished from Protozoa, namely, the differentiation of large and small sexual cells from each other and from the remaining cells of the body, has been broken down by the discovery of numerous cases of such differentiation among Protozoa. The Coelentera, as contrasted with other Metazoa (but not Parazoa), consist of two layers of cells only, an outer layer or ectoderm, an inner layer or endoderm. They have hence been described as Diploblastica. In the remaining Metazoa certain cells are budded off at an early stage of development from one or both of the two original layers, to form later a third layer, the mesoderm, which lies between the ectoderm and endoderm; such forms have therefore received the name Triploblastica. At the same time it is necessary to observe that it is by no means certain that the mesoderm found in various groups of Metazoa is a similar or homologous formation in all cases. A second essential difference between Coelentera and other Metazoa (except Parazoa) is that in the former all spaces in the interior of the body are referable to a single cavity of endodermal origin, the "gastro-vascular cavity," often termed the coelenteron: the spaces are always originally continuous with one another, and are in almost every case permanently so. This single cavity and its lining serve apparently for all those functions (digestion, excretion, circulation and often reproduction) which in more complex organisms are distributed among various cavities of independent and often very diverse origin.

In the Coelentera the ectoderm and endoderm are set apart from one another at a very early period in the life-history; generally either by delamination or invagination, processes described in the article EMBRYOLOGY. Between these two cell-layers a mesogloea (G. C. Bourne, 1887) is always intercalated as a secretion by one or both of them; this is a gelatinoid, primitively structureless lamella, which in the first instance serves merely as a basal support for the cells. In many cases, as, for example, in the Medusae or jelly-fish, the mesogloea may be so thick as to constitute the chief part of the body in bulk and weight. The ectoderm rarely consists of more than one layer of cells: these are divisible by structure and function into nervous, muscular and secretory cells, supported by interstitial cells. The endoderm is generally also an epithelium one cell in thickness, the cells being digestive, secretory and sometimes muscular. Reproductive sexual cells may be found in either of these two layers, according to the class and sub-class in question. The mesogloea is in itself an inert non-cellular secretion, but the immigration of muscular and other cells into its substance, from both ectoderm and endoderm, gives it in many cases a strong resemblance to the mesoderm of Triploblastica,--a resemblance which, while probably superficial, may yet serve to indicate the path of evolution of the mesoderm.

The Coelentera may thus be briefly defined as Metazoa which exhibit two embryonic cell-layers only,--the ectoderm and endoderm,--their body-cavities being referable to a single cavity or coelenteron in the endoderm. Their position in the animal kingdom and their main subdivisions may be expressed in the following table:--

I. PROTOZOA. II. PARAZOA or PORIFERA. III. METAZOA. | +----------+--------------+ | | Coelentera Triploblastica = Diploblastica. (including Coelomata). | +------+-----------+-----------------+ | | | Hydromedusae. Scyphozoa. Ctenophora. | +--------+----------+ | | Scyphomedusae. Anthozoa.

In the above-given classification, the Scyphomedusae, formerly included with the Hydromedusae as Hydrozoa, are placed nearer the Anthozoa. The reasons for this may be stated briefly.

The HYDROMEDUSAE are distinguished from the Scyphozoa chiefly by negative characters; they have no stomodaeum, that is, no ingrowth of ectoderm at the mouth to form an oesophagus; they have no mesenteries (radiating partitions) which incompletely subdivide the coelenteron; and they have no concentration of digestive cells into special organs. Their ectodermal muscles are mainly longitudinal, their endodermal muscles are circularly arranged on the body-wall. Their sexual cells are (probably in all cases) produced from the ectoderm, and lie in those radii which are first accentuated in development. They typically present two structural forms, the non-sexual hydroid and the sexual medusoid; in such a case there is an alternation of generations (metagenesis), the hydroid giving rise to the medusoid by a sexual gemmation, the medusoid bearing sexual cells which develop into a hydroid. In some other cases medusoid develops directly from medusoid (hypogenesis), whether by sexual cells or by gemmation. The medusoids have a muscular velum of ectoderm and mesogloea only.

The SCYPHOZOA have the following features in common:--They typically exhibit an ectodermal stomodaeum; partitions or mesenteries project into their coelenteron from the body-wall, and on these are generally concentrated digestive cells (to form mesenterial filaments, phacellae or gastric filaments, &c.); the external musculature of the body-wall is circular (except in _Cerianthus_); the internal, longitudinal; and the sexual cells probably always arise in the endoderm.

The SCYPHOMEDUSAE, like the Hydromedusae, typically present a metagenesis, the non-sexual scyphistomoid (corresponding to the hydroid) alternating with the sexual medusoid. In other cases the medusoid is hypogenetic, medusoid producing medusoid. The sexual cells of the medusoid lie in the endoderm on interradii, that is, on the second set of radii accentuated in the course of development. The medusoids have no true velum; in some cases a structure more or less resembling this organ, termed a velarium, is present, permeated by endodermal canals.

The ANTHOZOA differ from the Scyphomedusae in having no medusoid form; they all more or less resemble a sea-anemone, and may be termed actinioid. They are (with rare exceptions, probably secondarily acquired) hypogenetic, the offspring resembling the parent, and both being sexual. The sexual cells are borne on the mesenteries in positions irrespective of obvious developmental radii.

The CTENOPHORA are so aberrant in structure that it has been proposed to separate them from the Coelentera altogether: they are, however, theoretically deducible from an ancestor common to other Coelentera, but their extreme specialization precludes the idea of any close relationship with the rest.

As regards the other three groups, however, it is easy to conceive of them as derived from an ancestor, represented to-day to some extent by the planula-larva, which was Coelenterate in so far as it was composed of an ectoderm and endoderm, and had an internal digestive cavity (I. of the table).

At the point of divergence between Scyphozoa and Hydromedusae (II. of the table of hypothetical descent), we may conceive of its descendant as tentaculate, capable of either floating (swimming) or fixation at will like Lucernaria to-day; and exhibiting incipient differentiation of myoepithelial cells (formerly termed neuro-muscular cells). At the parting of the ways which led, on the one hand, to modern Scyphomedusae, on the other to Anthozoa (III.), it is probable that the common ancestor was marked by incipient mesenteries and by the limitation of the sexual cells to endoderm. The lines of descent--II. to Hydromedusae, and III. to Scyphomedusae--represent periods during which the hypothetical ancestors II. and III., capable of either locomotion or fixation at will, were either differentiated into alternating generations of fixed sterile nutritive hydroids (scyphistomoids) and locomotor sexual medusoids, or abandoned the power of fixation in hypogenetic cases. During the period represented by the line of descent--III. to Anthozoa--this group abandoned its power of adult locomotion by swimming. During these periods were also attained those less important structural characters which these three groups present to-day. (G. H. Fo.)

COELLO, ALONSO SANCHEZ (1515-1590), Spanish painter, according to some authorities a native of Portugal, was born, according to others, at Benifacio, near the city of Valencia. He studied many years in Italy; and returning to Spain in 1541 he settled at Madrid, and worked on religious themes for most of the palaces and larger churches. He was a follower of Titian, and, like him, excelled in portraits and single figures, elaborating the textures of his armours, draperies, and such accessories in a manner so masterly as strongly to influence Velazquez in his treatment of like objects. Many of his pictures were destroyed in the fires that consumed the Madrid and Prado palaces, but many good examples are yet extant, among which may be noted the portraits of the infantes Carlos and Isabella, now in the Madrid gallery, and the St Sebastian painted in the church of San Gerónimo, also in Madrid. Coello left a daughter, Isabella Sanchez, who studied under him, and painted excellent portraits.

COELLO, ANTONIO (1610?-1652), Spanish dramatist and poet, was born at Madrid about the beginning of the 17th century. He entered the household of the duke de Albuquerque, and after some years of service in the army received the order of Santiago in 1648. He was a favourite of Philip IV., who is reported to have collaborated with him; this rumour is not confirmed, but there is ample proof of Coello's collaboration with Calderón, Rojas Zorrilla, Solís and Velez de Guevara, the most distinguished dramatists of the age. The best of his original plays, _Los Empeños de seis horas_, has been wrongly ascribed to Calderón; it was adapted by Samuel Tuke, under the title of _The Adventures of five Hours_, and was described by Pepys as superior to _Othello_. It is an excellent example of stagecraft and animated dialogue. Coello died on the 20th of October 1652, shortly after his nomination to a post in the household of Philip IV.

COELOM AND SEROUS MEMBRANES. In human anatomy the body-cavity or coelom (Gr. [Greek: koilos], hollow) is divided into the _pericardium_, the two _pleurae_, the _peritoneum_ and the two _tunicae vaginales_.

The _pericardium_ is a closed sac which occupies the central part of the thorax and contains the heart. Like all the serous membranes it has a visceral and a parietal layer, the former of which is closely applied to the heart and consists of endothelial cells with a slight fibrous backing: to it is due the glossy appearance of a freshly removed heart. The parietal layer is double; externally there is a strong fibrous protective coat which is continuous with the other fibrous structures in the neighbourhood, especially with the sheaths of the great vessels at the root of the heart, with prolongations of the fascia of the neck, and with the central tendon of the diaphragm, while internally is the serous layer which is reflected from the surface of the heart, where the great vessels enter, so that everywhere the two layers of the serous membrane are in contact, and the only thing within the cavity is a drop or two of the fluid secreted by the serous walls. When the parietal layer is laid open and the heart removed by cutting through the great vessels, it will be seen that there are two lines of reflection of the serous layer, one common to the aorta and pulmonary artery, the other to all the pulmonary veins and the two venae cavae.

The _pleurae_ very closely resemble the pericardium except that the fibrous outer coat of the parietal layer is not nearly as strong; it is closely attached to the inner surface of the chest walls and mesially to the outer layer of the pericardium; above it is thickened by a fibrous contribution from the scalene muscles, and this forms the _dome of the pleura_ which fits into the concavity of the first rib and contains the apex of the lung. The reflection of the serous layer of the pleura, from the parietal to the visceral part, takes place at the root of the lung, where the great vessels enter, and continues for some distance below this as the _ligamentum latum pulmonis_. The upper limit of the pleural cavity reaches about half an inch above the inner third of the clavicle, while, below, it may be marked out by a line drawn from the twelfth thoracic spine to the tenth rib in the mid axillary line, the eighth rib in the nipple line, and the sixth rib at its junction with the sternum. There is probably very little difference in the lower level of the pleurae on the two sides.

The _peritoneum_ is a more extensive and complicated membrane than either the pericardium or pleura; it surrounds the abdominal and pelvic viscera, and, like the other sacs, has a parietal and visceral layer. The line of reflection of these, though a continuous one, is very tortuous. The peritoneum consists of a _greater_ and _lesser sac_ which communicate through an opening known as the _foramen of Winslow_, and the most satisfactory way of understanding these is to follow the reflections first in a vertical median (sagittal) section and then in a horizontal one, the body being supposed to be in the upright position. If a median sagittal section be studied first, and a start be made at the umbilicus (see fig. 1), the parietal peritoneum is seen to run upward, lining the anterior abdominal wall, and then to pass along the under surface of the diaphragm till its posterior third is reached; here there is a reflection on to the liver (L), forming the anterior layer of the _coronary ligament_ of that viscus, while the membrane now becomes visceral and envelops the front of the liver as far back as the transverse fissure on its lower surface; here it is reflected on to the stomach (St) forming the anterior layer of the _gastro-hepatic_ or _lesser omentum_. It now covers the front of the stomach, and at the lower border runs down as the anterior layer of an apron-like fold, the _great omentum_, which in some cases reaches as low as the pubes; then it turns up again as the posterior or fourth layer of the great omentum until the transverse colon (C) is reached, the posterior surface of which it covers and is reflected, as the posterior layer of the _transverse meso-colon_, to the lower part of the pancreas (P); after this it turns down and covers the anterior surface of the third part of the duodenum (D) till the posterior wall of the abdomen is reached, from which it is reflected on to the small intestine (I) as the anterior layer of the _mesentery_, a fold varying from 5 to 8 in. between its attachments. After surrounding the small intestine it becomes the posterior layer of the mesentery and so again reaches the posterior abdominal wall, down which it runs until the rectum (R) is reached. The anterior surface of this tube is covered by peritoneum to a point about 3 in. from the anus, where it is reflected on to the uterus and vagina (V) in the female and then on to the bladder (B); in the male, on the other hand, the reflection is directly from the rectum to the bladder. At the apex of the bladder, after covering the upper surface of that organ, it is lifted off by the urachus and runs up the anterior abdominal wall to the umbilicus, from which the start was made. All this is the greater sac. The tracing of the lesser sac may be conveniently started at the transverse fissure of the liver, whence the membrane runs down to the stomach (St) as the posterior layer of the lesser omentum, lines the posterior surface of the stomach, passes down as the second layer of the great omentum and up again as the third layer, covers the anterior surface of the transverse colon (C) and then reaches the pancreas (P) as the anterior layer of the transverse mesocolon. After this it covers the front of the pancreas and in the middle line of the body runs up below the diaphragm to within an inch of the anterior layer of the coronary ligament of the liver; here it is reflected on to the top of the Spigelian lobe of the liver to form the posterior layer of the coronary ligament, covers the whole Spigelian lobe, and so reaches the transverse fissure, the starting-point.

This section, therefore, shows two completely closed sacs without any visible communication. In the female, however, the great sac is not absolutely closed, for the Fallopian tubes open into it by their minute _ostia abdominalia_, while at the other ends they communicate with the cavity of the uterus and so with the vagina and exterior.

A horizontal section through the upper part of the first lumbar vertebra will, if a fortunate one (see fig. 2), pass through the foramen of Winslow and show the communication of the two sacs. A starting-point may be made from the mid-ventral line and the parietal peritoneum traced round the left side of the body wall until the outer edge of the left kidney (K) is reached; here it passes in front of the kidney and is soon reflected off on to the spleen, which it nearly surrounds; just before it reaches the hilum of that organ, where the vessels enter, it is reflected on to the front of the stomach (St), forming the anterior layer of the _gastro-splenic omentum_; it soon reaches the lesser curvature of the stomach and then becomes the anterior layer of the lesser omentum, which continues until the bile duct (B.D) and portal vein (P.V) are reached at its right free extremity; here it turns completely round these structures and runs to the left again, as the posterior layer of the lesser omentum, behind the stomach (St) and then to the spleen (Sp) as the posterior layer of the gastro-splenic omentum. From the spleen it runs to the right once more, in front of the pancreas (P), until the inferior vena cava (V.C) is reached, and this point is just behind the portal vein and is the place where the lesser and greater sacs communicate, known as the foramen of Winslow. From this opening the lesser sac runs to the left, while all the rest of the peritoneal cavity in the section is greater sac. From the front of the vena cava the parietal peritoneum passes in front of the right kidney (K) and round the right abdominal wall to the mid-ventral line. The right part of this section is filled by the liver (L), which is completely surrounded by a visceral layer of peritoneum, and no reflection is usually seen at this level between it and the parietal layer. Some of the viscera, such as the kidneys and pancreas, are retro-peritoneal; others, such as the small intestines and transverse colon, are surrounded, except at one point where they are attached to the dorsal wall by a _mesentery_ or _mesocolon_ as the reflections are called; others again are completely surrounded, and of these the caecum is an example; while some, like the liver and bladder, have large uncovered areas, and the reflections of the membrane form ligaments which allow considerable freedom of movement.

The _tunica vaginalis_ is the remains of a process of the peritoneum (_processus vaginalis_) which descends into the scrotum during foetal life some little time before the testis itself descends. After the descent of the testis the upper part usually becomes obliterated, while the lower part forms a serous sac which nearly surrounds the testis, but does not quite do so. Posteriorly the epididymis is in close contact with the testis, and here the visceral layer is not in contact; there is, however, a pocket called the _digital fossa_ which squeezes in from the outer side between the testis and epididymis. The parietal layer lines the inner wall of its own side of the scrotum.

For a full description of the topography of the serous membranes see any of the standard text-books of anatomy, by Gray, Quain, Cunningham or Macalister. Special details will be found in Sir F. Treves' _Anatomy of the Intestinal Canal and Peritoneum_ (London, 1885); C. B. Lockwood, _Hunterian Lectures on Hernia_ (London, 1889); C. Addison, "Topographical Anatomy of the Abdominal Viscera in Man," _Jour. Anat._, vols. 34, 35; F. Dixon and A. Birmingham, "Peritoneum of the Pelvic Cavity," _Jour. Anat._ vol. 34, p. 127; W. Waldeyer, "Das Becken" (1899), and "Topographical Sketch of the Lateral Wall of the Pelvic Cavity," _Jour. Anat._ vol. 32; B. Moynihan, _Retroperitoneal Hernia_ (London, 1899). A complete bibliography of the subject up to 1895 will be found in _Quain's Anatomy_, vol. 3, part 4, p. 69.

_Embryology._--As the mesoderm is gradually spreading over the embryo it splits into two layers, the outer of which is known as the _somatopleure_ and lines the parietal or ectodermal wall, while the inner lines the entoderm and is called the _splanchnopleure_; between the two is the coelom. The pericardial area is early differentiated from the rest of the coelom and at first lies in front of the neural and bucco-pharyngeal area; here the mesoderm stretches right across the mid-line, which it does not in front and behind. As the head fold of the embryo is formed the pericardium is gradually turned right over, so that the dorsal side becomes the ventral and the anterior limit the posterior; this will be evident on referring to the two accompanying diagrams.

The two primitive aortae lie at first in the ventral wall of the pericardium, but with the folding over they come to lie in the dorsal wall and gradually bulge into the cavity as they coalesce to form the heart, so that the heart drops into the dorsal side of the pericardium and draws down a fold of the membrane called the _dorsal mesocardium_. In mammals A. Robinson (_Jour. Anat. and Phys._, xxxvii. 1) has shown that no ventral mesocardium exists, though in more lowly vertebrates it is present. Laterally the pericardial cavity communicates with the general cavity of the coelom, but with the growth of the Cuvierian ducts (see development of veins) these communications disappear. Originally the mesocardium runs the whole length of the pericardium from before backward, but later on the middle part becomes obliterated, and so the two separate reflections from the parietal to the visceral layer, already noticed, are accounted for.

Just behind the pericardium and in front of the umbilicus, which at first are close together, the mesoderm forms a mass which is called the _septum transversum_, and into this the developing lungs push bag-like protrusions of the coelom, consisting of visceral and parietal layers, and these eventually lose their connexion with the rest of the coelom, as the diaphragm develops, and become the pleural cavities. After the pericardium and pleurae have been separated off the remainder of the coelom becomes the peritoneum. At first the stomach and intestine form a straight tube, which is connected to the dorsum of the embryo by a _dorsal mesentery_ and to the mid-ventral wall in front of the umbilicus by a _ventral mesentery_. Into the ventral mesentery the liver grows as diverticula from the duodenum, so that some of the mesentery remains as the _falciform ligament_ of the liver and some as the lesser omentum. Into the dorsal mesentery the pancreas grows, also as diverticula, from the duodenum, while the spleen is developed from the mesoderm contained in the same fold. As the stomach turns over so that its left side becomes ventral, the dorsal mesentery attached to it becomes pulled out, in such a way that part of it forms the great omentum and part the gastro-splenic omentum. After the caecum is formed as a diverticulum from the intestine it is situated close to the liver and gradually travels down into the right iliac fossa. This passage to the right is accompanied by a throwing over of the duodenal loop to the right, so that the right side of its mesentery becomes pressed against the dorsal wall of the abdomen and obliterated. This accounts for the fact that the pancreas and duodenum are only covered by peritoneum on their anterior surfaces in man. The formation of the lesser sac is due to the turning over of the stomach to the right, with the result that a cave, known sometimes as the _bursa omentalis_, is formed behind it. Originally, of course, the whole colon had a _dorsal mesocolon_ continuous with the mesentery, but in the region of the ascending and descending colon this usually disappears and these parts of the gut are uncovered by peritoneum posteriorly. The transverse mesocolon persists and at first is quite free from the great omentum, but later, in man, the two structures fuse[1] and the fourth layer of the great omentum becomes continuous with the posterior layer of the transverse mesocolon.

For further details see Quain's _Anatomy_ (London, 1908).

_Comparative Anatomy._--In the Amphioxus the coelom is developed in the embryo as a series of bilateral pouches, called _enterocoeles_, from the sides of the alimentary canal; these are therefore entodermal in their origin, as in Sagitta and the Echinodermata among the invertebrates. In the adult the development of the atrium causes a considerable reduction of the coelom, represented by two dorsal coelomic canals communicating with a ventral canal by means of branchial canals which run down the outer side of the primary gill bars. Into the dorsal canals the nephridia open. In the intestinal region the coelom is only present on the left side.

In the higher vertebrates (_Craniata_) the coelom is developed by a splitting of the mesoderm into two layers, and a pericardium is constricted off from the general cavity. In all cases the ova burst into the coelom before making their way to the exterior, and in some cases, _e.g._ amphioxus, lamprey (Cyclostomata), eels and mud-fish (Dipnoi), the sperm cells do so too. The Cyclostomata have a pair of _genital pores_ which lead from the coelom into the urino-genital sinus, and so to the exterior.

In the Elasmobranch fish there is a _pericardio-peritoneal canal_ forming a communication between these two parts of the coelom; also a large common opening for the two oviducts in the region of the liver, and two openings, called _abdominal pores_, on to the surface close to the cloacal aperture. In the Teleostomi (Teleostean and Ganoid fish) abdominal pores are rare, but in most Teleostei (bony fish) the ova pass directly down oviducts, as they do in Arthropods, without entering the peritoneal cavity; there is little doubt, however, that these oviducts are originally coelomic in origin. In the Dipnoi (mud-fish) abdominal pores are found, and probably serve as a passage for the sperm cells, since there are no vasa deferentia. In fishes a complete dorsal mesentery is seldom found in the adult; in many cases it only remains as a tube surrounding the vessels passing to the alimentary canal.

In the Amphibia, Reptilia and Aves, one cavity acts as pleura and peritoneum, though in the latter the lungs are not completely surrounded by a serous membrane. In many lizards the comparatively straight intestine, with its continuous dorsal mesentery and ventral mesentery in the anterior part of the abdomen, is very like a stage in the development of the human and other mammalian embryos. In the mammalia the diaphragm is complete (see DIAPHRAGM) and divides the pleuro-peritoneal cavity into its two constituent parts. In the lower mammals the derivatives of the original dorsal mesentery do not undergo as much fusion and obliteration as they do in adult man; the ascending and descending mesocolon is retained, and the transverse mesocolon contracts no adhesion to the great omentum. It is a common thing, however, to find a fenestrated arrangement of the great omentum which shows that its layers have been completely obliterated in many places.

In those animals, such as the rabbit, in which the tests are sometimes in the scrotum and sometimes in the abdomen, the communication between the peritoneum and the tunica vaginalis remains throughout life.

FOOTNOTE:

[1] Some authorities hold that this alteration is not brought about by fusion, but by a dragging away of the posterior layer of the great omentum from the dorsal wall of the abdomen.

COEN, JAN PIETERSZOON (1587-1630), fourth governor-general of the Dutch East Indies, was born at Hoorn, and spent his youth at Rome in the house of the famous merchants the Piscatori. In 1607 he sailed from Amsterdam to the Indies as second commercial agent, and remained away four years. He had proved so capable that in 1612 he was sent out a second time at the head of a trading expedition. In the following year he was made a councillor and director-general of the East Indian trade. Afterwards he became president at Bantam, and on the 31st of October 1617 he was promoted in succession to Laurens Reaal to the post of governor-general. To his vigour and intrepidity the Dutch in no small measure owed the preservation and establishment of their empire in the East. He took and destroyed Jacatra, and founded on its ruins the capital of the Dutch East Indies, to which he gave the name of Batavia. In 1622 Coen obtained leave to resign his post and return to Holland, but in his absence great difficulties had arisen with the English at Amboina (the so-called massacre of Amboina), and in 1627 under pressure from the directors of the East India Company he again returned as governor-general to Batavia. In 1629 he was able to beat off a formidable attack of the sultan of Mataram, sometimes styled emperor of Java, upon Batavia. He died the following year.

COENACULUM, the term applied to the eating-room of a Roman house in which the supper (_coena_) or latest meal was taken. It was sometimes placed in an upper storey and reached by an external staircase. The Last Supper in the New Testament was taken in the Coenaculum, the "large upper room" cited in St Mark (xiv. 15) and St Luke (xxii. 12).

COENWULF (d. 821), king of Mercia, succeeded to the throne in 796, on the death of Ecgfrith, son of Offa. His succession is somewhat remarkable, as his direct ancestors do not seem to have held the throne for six generations. In 798 he invaded Kent, deposed and imprisoned Eadberht Præn, and made his own brother Cuthred king. Cuthred reigned in Kent from 798 to 807, when he died, and Coenwulf seems to have taken Kent into his own hands. It was during this reign that the archbishopric of Lichfield was abolished, probably before 803, as the Hygeberht who signed as an abbot at the council of Cloveshoe in that year was presumably the former archbishop. Coenwulf appears from the charters to have quarrelled with Wulfred of Canterbury, who was consecrated in 806, and the dispute continued for several years. It was probably only settled at Cloveshoe in 825, when the lawsuit of Cwoenthryth, daughter and heiress of Coenwulf, with Wulfred was terminated. Coenwulf may have instigated the raid of Æthelmund, earl of the Hwicce, upon the accession of Ecgberht. He died in 821, and was succeeded by his brother Ceolwulf I.

See Earle and Plummer's edition of the _Anglo-Saxon Chronicle_, 796, 819 (Oxford, 1892); W. de G. Birch, _Cartularium Saxonicum_, 378 (London, 1885-1893). (F. G. M. B.)

COERCION (from Lat. _coercere_, to restrain), an application of moral or physical compulsion by which a person is forced to do or refrain from doing some act or set of acts apart from his own voluntary motion. Where the coercion is direct or positive, _i.e._ where the person is compelled by physical force to do an act contrary to his will,--for example, when a man is compelled to join a rebel army, and to serve as a soldier under threats of death,--his act is not legally a crime. Where the coercion is implied, as when a person is legally under subjection to another, the person coerced, having no will on the subject, is not responsible. But this principle is applied only within narrow limits, and does not extend to the command of a superior to an inferior; of a parent to a child; of a master to his servant or a principal to his agent. Where, however, a married woman commits a crime in the presence of her husband, she is generally presumed to have acted by his coercion, and to be entitled to acquittal, but this presumption does not extend to grave crimes, nor to those in which the principal part may be supposed to be taken by the woman, such as keeping a brothel. In civil matters, such as the making of a contract, where the law requires the free assent of the person who undertakes the obligation, coercion is a ground for invalidating the instrument.

The term "coercion" is inevitably somewhat ambiguous, and depends on the circumstances of the case. In a political sense, the application of the Crimes Act of 1887 to Ireland was called "coercion" by those opposed to the English Unionist party and government, as being special legislation differing from the ordinary law applicable in the United Kingdom.

COEUR, JACQUES (_c._ 1395-1456), founder of the trade between France and the Levant, was born at Bourges, in which city his father, Pierre Coeur, was a rich merchant. Jacques is first heard of about 1418, when he married Macée de Léodepart, daughter of Lambert de Léodepart, an influential citizen, provost of Bourges, and a former valet of John, duke of Berry. About 1429 he formed a commercial partnership with two brothers named Godard; and in 1432 he was at Damascus, buying and bartering, and transporting the wares of the Levant--gall-nuts, wools and silks, goats' hair, brocades and carpets--to the interior of France by way of Narbonne. In the same year he established himself at Montpellier, and there began those gigantic operations which have made him illustrious among financiers. Details are wanting; but it is certain that in a few years he placed his country in a position to contend not unsuccessfully with the great trading republics of Italy, and acquired such reputation as to be able, mere trader as he was, to render material assistance to the knights of Rhodes and to Venice herself.

In 1436 Coeur was summoned to Paris by Charles VII., and made master of the mint that had been established in that city. The post was of vast importance, and the duties onerous. The country was deluged with the base moneys of three reigns, charged with superscriptions both French and English, and Charles had determined on a sweeping reform. In this design he was ably seconded by the merchant, who, in fact, inspired or prepared all the ordinances concerning the coinage of France issued between 1435 and 1451. In 1438 he was made steward of the royal expenditure; in 1441 he and his family were ennobled by letters patent. In 1444 he was sent as one of the royal commissioners to preside over the new parlement of Languedoc, a dignity he bore till the day of his disgrace. In 1445 his agents in the East negotiated a treaty between the sultan of Egypt and the knights of Rhodes; and in 1447, at his instance, Jean de Village, his nephew by marriage, was charged with a mission to Egypt. The results were most important; concessions were obtained which greatly improved the position of the French consuls in the Levant, and that influence in the East was thereby founded which, though often interrupted, was for several centuries a chief commercial glory of France. In the same year Coeur assisted in an embassy to Amadeus VIII., former duke of Savoy, who had been chosen pope as Felix V. by the council of Basel; and in 1448 he represented the French king at the court of Pope Nicholas V., and was able to arrange an agreement between Nicholas and Amadeus, and so to end the papal schism. Nicholas treated him with the utmost distinction, lodged him in the papal palace, and gave him a special licence to traffic with the infidels. From about this time he made large advances to Charles for carrying on his wars; and in 1449, after fighting at the king's side through the campaign, he entered Rouen in his train.

At this moment the great trader's glory was at its height. He had represented France in three embassies, and had supplied the sinews of that war which had ousted the English from Normandy. He was invested with various offices of dignity, and possessed the most colossal fortune that had ever been amassed by a private Frenchman. The sea was covered with his ships; he had 300 factors in his employ, and houses of business in all the chief cities of France. He had built houses and chapels, and had founded colleges in Paris, at Montpellier and at Bourges. The house at Bourges (see HOUSE, Plate II. figs. 7 and 8) was of exceptional magnificence, and remains to-day one of the finest monuments of the middle ages in France. He also built there the sacristy of the cathedral and a sepulchral chapel for his family. His brother Nicholas was made bishop of Luçon, his sister married Jean Bochetel, the king's secretary, his daughter married the son of the viscount of Bourges, and his son Jean became archbishop of Bourges. But Coeur's gigantic monopoly caused his ruin. Dealing in everything, money and arms, peltry and jewels, brocades and woollens--a broker, a banker, a farmer--he had absorbed the trade of the country, and merchants complained they could make no gains on account of "that Jacquet." He had lent money to needy courtiers, to members of the royal family, and to the king himself, and his debtors, jealous of his wealth, were eager for a chance to cause his overthrow.

In February 1450 Agnes Sorel, the king's mistress, suddenly died. Eighteen months later it was rumoured that she had been poisoned, and a lady of the court who owed money to Jacques Coeur, Jeanne de Vendôme, wife of François de Montberon, and an Italian, Jacques Colonna, formally accused him of having poisoned her. There was not even a pretext for such a charge, but for this and other alleged crimes the king, on the 31st of July 1451, gave orders for his arrest and for the seizure of his goods, reserving to himself a large sum of money for the war in Guienne. Commissioners extraordinary, the merchant's declared enemies, were chosen to conduct the trial, and an inquiry began, the judges in which were either the prisoner's debtors or the holders of his forfeited estates. He was accused of having paid French gold and ingots to the infidels, of coining light money, of kidnapping oarsmen for his galleys, of sending back a Christian slave who had taken sanctuary on board one of his ships, and of committing frauds and exactions in Languedoc to the king's prejudice. He defended himself with all the energy of his nature. His innocence was manifest; but a conviction was necessary, and in spite of strenuous efforts on the part of his friends, after twenty-two months of confinement in five prisons, he was condemned to do public penance for his fault, to pay the king a sum equal to about £1,000,000 of modern money, and to remain a prisoner till full satisfaction had been obtained; his sentence also embraced confiscation of all his property, and exile during royal pleasure. On the 5th of June 1453 the sentence took effect; at Poitiers the shameful form of making honourable amends was gone through; and for nearly three years nothing is known of him. It is probable that he remained in prison; it is certain that his vast possessions were distributed among the intimates of Charles.

In 1455 Jacques Coeur, wherever confined, contrived to escape into Provence. He was pursued; but a party, headed by Jean de Village and two of his old factors, carried him off to Tarascon, whence, by way of Marseilles, Nice and Pisa, he managed to reach Rome. He was honourably and joyfully received by Nicholas V., who was fitting out an expedition against the Turks. On the death of Nicholas, Calixtus III. continued his work, and named his guest captain of a fleet of sixteen galleys sent to the relief of Rhodes. Coeur set out on this expedition, but was taken ill at Chios, and died there on the 25th of November 1456. After his death Charles VII. showed himself well disposed to the family, and allowed Jacques Coeur's sons to come into possession of whatever was left of their father's wealth.

COEUR D'ALÊNE ("awl-heart," the French translation of the native name _skitswish_), a tribe of North American Indians of Salishan stock. The name is said to have been originally that of a chief noted for his cruelty. The tribe has given its name to a lake, river and range of mountains in Idaho, where on a reservation the survivors, some 400, are settled.

COFFEE (Fr: _café_, Ger. _Kaffee_). This important and valuable article of food is the produce chiefly of _Coffea arabica_, a Rubiaceous plant indigenous to Abyssinia, which, however, as cultivated originally, spread outwards from the southern parts of Arabia. The name is probably derived from the Arabic K'h[=a]wah, although by some it has been traced to Kaffa, a province in Abyssinia, in which the tree grows wild.

The genus _Coffea_, to which the common coffee tree belongs, contains about 25 species in the tropics of the Old World, mainly African. Besides being found wild in Abyssinia, the common coffee plant appears to be widely disseminated in Africa, occurring wild in the Mozambique district, on the shores of the Victoria Nyanza, and in Angola on the west coast. The coffee leaf disease in Ceylon brought into prominence Liberian coffee (_C. liberica_), a native of the west coast of Africa, now extensively grown in several parts of the world. Other species of economic importance are Sierra Leone coffee (_C. stenophylla_) and Congo coffee (_C. robusta_), both of which have been introduced into and are cultivated on a small scale in various parts of the tropics. _C. excelsa_ is another species of considerable promise.

The common Arabian coffee shrub is an evergreen plant, which under natural conditions grows to a height of from 18 to 20 ft., with oblong-ovate, acuminate, smooth and shining leaves, measuring about 6 in. in length by 2½ wide. Its flowers, which are produced in dense clusters in the axils of the leaves, have a five-toothed calyx, a tubular five-parted corolla, five stamens and a single bifid style. The flowers are pure white in colour, with a rich fragrant odour, and the plants in blossom have a lovely and attractive appearance, but the bloom is very evanescent. The fruit is a fleshy berry, having the appearance and size of a small cherry, and as it ripens it assumes a dark red colour. Each fruit contains two seeds embedded in a yellowish pulp, and the seeds are enclosed in a thin membranous endocarp (the "parchment"). Between each seed and the parchment is a delicate covering called the "silver skin." The seeds which constitute the raw coffee "beans" of commerce are plano-convex in form, the flat surfaces which are laid against each other within the berry having a longitudinal furrow or groove. When only one seed is developed in a fruit it is not flattened on one side, but circular in cross section. Such seeds form "pea-berry" coffee.

The seeds are of a soft, semi-translucent, bluish or greenish colour, hard and tough in texture. The regions best adapted for the cultivation of coffee are well-watered mountain slopes at an elevation ranging from 1000 to 4000 ft. above sea-level, within the tropics, and possessing a mean annual temperature of about 65° to 70° F.

The Liberian coffee plant (_C. liberica_) has larger leaves, flowers and fruits, and is of a more robust and hardy constitution, than Arabian coffee. The seeds yield a highly aromatic and well-flavoured coffee (but by no means equal to Arabian), and the plant is very prolific and yields heavy crops. Liberian coffee grows, moreover, at low altitudes, and flourishes in many situations unsuitable to the Arabian coffee. It grows wild in great abundance along the whole of the Guinea coast.

_History._--The early history of coffee as an economic product is involved in considerable obscurity, the absence of fact being compensated for by a profusion of conjectural statements and mythical stories. The use of coffee (_C. arabica_) in Abyssinia was recorded in the 15th century, and was then stated to have been practised from time immemorial. Neighbouring countries, however, appear to have been quite ignorant of its value. Various legendary accounts are given of the discovery of the beneficial properties of the plant, one ascribing it to a flock of sheep accidentally browsing on the wild shrubs, with the result that they became elated and sleepless at night! Its physiological action in dissipating drowsiness and preventing sleep was taken advantage of in connexion with the prolonged religious service of the Mahommedans, and its use as a devotional antisoporific stirred up fierce opposition on the part of the strictly orthodox and conservative section of the priests. Coffee by them was held to be an intoxicating beverage, and therefore prohibited by the Koran, and severe penalties were threatened to those addicted to its use. Notwithstanding threats of divine retribution and other devices, the coffee-drinking habit spread rapidly among the Arabian Mahommedans, and the growth of coffee and its use as a national beverage became as inseparably connected with Arabia as tea is with China.

Towards the close of the 16th century the use of coffee was recorded by a European resident in Egypt, and about this epoch it came into general use in the near East. The appreciation of coffee as a beverage in Europe dates from the 17th century. "Coffee-houses" were soon instituted, the first being opened in Constantinople and Venice. In London coffee-houses date from 1652, when one was opened in St Michael's Alley, Cornhill. They soon became popular, and the role played by them in the social life of the 17th and 18th centuries is well known. Germany, France, Sweden and other countries adopted them at about the same time as Great Britain. In Europe, as in Arabia, coffee at first made its way into favour in the face of various adverse and even prohibitive restrictions. Thus at one time in Germany it was necessary to obtain a licence to roast coffee. In England Charles II. endeavoured to suppress coffee-houses on the ground that they were centres of political agitation, his royal proclamation stating that they were the resort of disaffected persons "who devised and spread abroad divers false, malicious and scandalous reports, to the defamation of His Majesty's government, and to the disturbance of the peace and quiet of the nation."

Up to the close of the 17th century the world's entire, although limited, supply of coffee was obtained from the province of Yemen in south Arabia, where the true celebrated Mocha or Mokka coffee is still produced. At this time, however, plants were successfully introduced from Arabia to Java, where the cultivation was immediately taken up. The government of Java distributed plants to various places, including the botanic garden of Amsterdam. The Portuguese introduced coffee into Ceylon. From Amsterdam the Dutch sent the plant to Surinam in 1718, and in the same year Jamaica received it through the governor Sir Nicholas Lawes. Within a few years coffee reached the other West Indian islands, and spread generally through the tropics of the New World, which now produce by far the greater portion of the world's supply.

_Cultivation and Preparation for Market._--Coffee plants are grown from seeds, which, as in the case of other crops, should be obtained from selected trees of desirable characteristics. The seeds may be sown "at stake," _i.e._ in the actual positions the mature plants are to occupy, or raised in a nursery and afterwards transplanted. The choice of methods is usually determined by various local considerations. Nurseries are desirable where there is risk of drought killing seedlings in the open. Whilst young the plants usually require to be shaded, and this may be done by growing castor oil plants, cassava (_Manihot_), maize or Indian corn, bananas, or various other useful crops between the coffee, until the latter develop and occupy the ground. Sometimes, but by no means always, permanent shading is afforded by special shade trees, such as species of the coral tree (_Erythrina_) and other leguminous trees. Opinions as to the necessity of shade trees varies in different countries; _e.g._ in Brazil and at high elevations in Jamaica they are not employed, whereas in Porto Rico many look on them as absolutely essential. It is probable that in many cases where shade trees are of advantage their beneficial action may be indirect, in affording protection from wind, drought or soil erosion, and, when leguminous plants are employed, in enriching the soil in nitrogen. The plants begin to come into bearing in their second or third year, but on the average the fifth is the first year of considerable yield. There may be two, three, or even more "flushes" of blossom in one year, and flowers and fruits in all stages may thus be seen on one plant. The fruits are fully ripe about seven months after the flowers open; the ripe fruits are fleshy, and of a deep red colour, whence the name of "cherry." When mature the fruits are picked by hand, or allowed to fall of their own accord or by shaking the plant. The subsequent preparation may be according to (1) the dry or (2) the wet method.

In the dry method the cherries are spread in a thin layer, often on a stone drying floor, or barbecue, and exposed to the sun. Protection is necessary against heavy dew or rain. The dried cherries can be stored for any length of time, and later the dried pulp and the parchment are removed, setting free the two beans contained in each cherry. This primitive and simple method is employed in Arabia, in Brazil and other countries. In Brazil it is giving place to the more modern method described below.

In the wet, or as it is sometimes called, West Indian method, the cherries are put in a tank of water. On large estates galvanized spouting is often employed to convey the beans by the help of running water from the fields to the tank. The mature cherries sink, and are drawn off from the tank through pipes to the pulping machines. Here they are subjected to the action of a roughened cylinder revolving closely against a curved iron plate. The fleshy portion is reduced to a pulp, and the mixture of pulp and liberated seeds (each still enclosed in its parchment) is carried away to a second tank of water and stirred. The light pulp is removed by a stream of water and the seeds allowed to settle. Slight fermentation and subsequent washings, accompanied by trampling with bare feet and stirring by rakes or special machinery, result in the parchment coverings being left quite clean. The beans are now dried on barbecues, in trays, &c., or by artificial heat if climatic conditions render this necessary. Recent experiments in Porto Rico tend to show that if the weather is unfavourable during the crop period the pulped coffee can be allowed to remain moist and even to malt or sprout without injury to the final value of the product when dried later. The product is now in the state known as parchment coffee, and may be exported. Before use, however, the parchment must be removed. This may be done on the estate, at the port of shipment, or in the country where imported. The coffee is thoroughly dried, the parchment broken by a roller, and removed by winnowing. Further rubbing and winnowing removes the silver skin, and the beans are left in the condition of ordinary unroasted coffee. Grading into large, medium and small beans, to secure the uniformity desirable in roasting, is effected by the use of a cylindrical or other pattern sieve, along which the beans are made to travel, encountering first small, then medium, and finally large apertures or meshes. Damaged beans and foreign matter are removed by hand picking. An average yield of cleaned coffee is from 1½ to 2 lb per tree, but much greater crops are obtained on new rich lands, and under special conditions.

_Production._--The centre of production has shifted greatly since coffee first came into use in Europe. Arabia formerly supplied the world; later the West Indies and then Java took the lead, to be supplanted in turn by Brazil, which now produces about three-quarters of the world's supply and controls the market.

_Brazil._--Coffee planting is the chief industry of Brazil, and coffee the principal export. The states of São Paulo, Rio de Janeiro, Minas Geraes and Santos, contain the chief coffee-producing lands. The annual output ranges from about 10,000,000 to 16,000,000 bags (of 120 lb each), whilst the world's annual consumption is more or less stationary at about 16,000,000 bags. The overwhelming importance of the Brazilian output is thus evident. Recently efforts have been made to restrict production to maintain prices, and the Coffee Convention scheme came into force in São Paulo on December 1, 1906, and in Rio de Janeiro and Minas Geraes on January 1, 1907. The cultivation in general is very primitive in character, periodical weeding being almost all the attention the plants receive. Manuring is commonly confined to mulches of the cut weeds and addition of the coffee husks. New lands in São Paulo yield from 80 cwt. to 100 cwt. of cleaned coffee per 1000 trees (700 go to the acre); the average yield, however, is not more than 15 cwt. The plants are at their best when from 10 to 15 years old, but continue yielding for 30 years or even more.

_Other South American Countries._--Venezuela, Colombia, Ecuador, Peru, and to a much less degree Bolivia and Paraguay, produce coffee, the annual crops of the two former countries being each of about £1,500,000 in value.

_Central America._--Guatemala produces the most in this region; the coffee estates are mainly controlled by Germans, who have brought them to a high pitch of perfection. The crop ranges in value from about £1,000,000 to £1,500,000 per annum. Costa Rica and San Salvador produce about half this amount. In Nicaragua, Honduras and Panama, coffee is extensively cultivated, and all export the product.

_West Indies._--Coffee is grown in most of the islands, often only for local use. Haiti produces the largest amount, the annual value of the crop being about £500,000. Porto Rico formerly had a flourishing industry, but it has declined owing to various causes. The interior is still expected to be devoted largely to coffee, and the U.S. Department of Agriculture has carried out experiments to improve methods and ensure the cultivation of better varieties. Jamaica produces the famous Blue Mountain Coffee, which compares favourably with the best coffees of the world, and also ordinary or "plain grown"; the Blue Mountain is cultivated at elevations of from 3000 to 4500 ft. Coffee usually ranks third or fourth in value amongst the exports of the island.

_Africa_, the native country of the coffees, does not now contribute any important amount to the world's output. In Liberia, the Gold Coast and elsewhere on the West Coast are many plantations, but the low prices ruling of recent years have caused coffee to be neglected for more remunerative crops. Coffee is, however, still the principal export of Nyasaland (British Central Africa), where it was introduced as recently as 1894. The area under coffee has been greatly reduced, owing partly to more attention being paid to cotton, partly to droughts and other causes. In Somaliland and Abyssinia coffee cultivation is of very ancient date. Two kinds are exported, Harrari and Habashi. The former compares favourably with Mocha coffee. The industry could be very considerably extended. In Natal, Rhodesia, &c., coffee is grown, but not in sufficient quantity to supply the local demand.

_Arabia._--The name "Mocha" is applied generally to coffee produced in Arabia. Turkey and Egypt obtain the best grades. Traders from these countries go to Arabia, buy the crops on the trees, and supervise its picking and preparation themselves. The coffee is prepared by the "dry method."

_India_ is the principal coffee-growing region in the British empire, and produces about one-fifth of the total supply of the United Kingdom. There are some 213,000 acres under coffee, mostly in southern India. The official report states that the production of coffee is restricted for the most part to a limited area in the elevated region above the south-western coast, the coffee lands of Mysore, Coorg, and the Madras districts of Malabar and the Nilgiris, comprising 86% of the whole area under the plant in India. About one-half of the whole coffee-producing area is in Mysore. In Burma, Assam and Bombay, coffee is of minor importance. During 1904-1906 there was a reduction of the area under coffee in India by 21,554 acres.

_Ceylon._--The history of coffee in Ceylon is practically that of the coffee-leaf disease (see below). The Dutch introduced Arabian coffee in 1720, but abandoned its cultivation later. It was revived by the British, and developed very rapidly between 1836 and 1845, when there was a temporary collapse owing to financial crisis in the United Kingdom. In 1880 the exports of coffee were of the value of about £2,784,163. Ten years later they had fallen to £430,633, owing to the ravages of the coffee-leaf disease. The output continued to decrease, and the value of the crop in 1906 was only £17,258. Liberian coffee, which is hardier and more resistant to disease, was introduced, but met with only partial success.

_Dutch East Indies._--Coffee from this source passes under the general name of "Java," that island producing the greatest amount; Sumatra, Borneo and the Celebes, &c., however, also contribute. The Java plantations are largely owned by the government. Much of the coffee from these islands is of a high quality.

_Australasia._--Coffee can be cultivated in the northern territories of Australia, but comparatively little is done with this crop; Queensland produces the largest amount.

_Hawaii_, &c.--In all the islands of the Hawaiian group coffee is grown, but nine-tenths or more is raised in Hawaii itself, the Kona district being the chief seat of production. The exports go mostly to the United States, and there is also a large local consumption.

Coffee thrives well also in the Philippines and Guam.

_The World's Trade._--The following figures, from the _Year-book_ of the U.S. Department of Agriculture, indicate the relative importance of the coffee-exporting countries.

_Other countries_ 216,891,567 220,132,690 ------------- ------------- Total 2,268,109,976 2,238,581,412

In 1906 there was an increased total of 2,680,855,878 lb, due to the Brazil export rising to 1,847,367,771 lb. The aggregate value of the coffee annually entering the world's markets is about £40,000,000.

_Coffee Consumption._--The United States of America consume nearly one half of all the coffee exported from the producing countries of the world. This might of course be due merely to the States containing more coffee-drinkers than other countries, but the average consumption per head in the country is about 11 to 12 lb per annum, an amount equalled or excelled only in Norway, Sweden and Holland. Whilst one great branch of the Anglo-Saxon stock is near the head of the list, it is interesting to note that the United Kingdom and also Canada and Australia are almost at the foot, using only about 1 lb of coffee per head each year. Germany, with a consumption of about 6 to 7 lb per person per annum uses considerably less than a quarter of the world's commercial crop. France, about 5 lb per head, takes about one eighth; and Austria-Hungary, about 2 lb, uses some one-sixteenth. Holland consumes approximately as much, but with a much smaller population, the Dutch using more per head than any other people--14 lb to 15 lb per annum. Their taste is seen also in the relatively high consumption in South Africa. Sweden, Belgium and the United Kingdom, follow next in order of total amount used.

In many tropical countries much coffee is drunk, but as it is often produced locally exact figures are not available. The average consumption in the United Kingdom is about 50,000,000 lb per annum; about one-fifth only is produced in the British empire, and of this about nineteen-twentieths come from India and one-twentieth from the British West Indies.

_Coffee-leaf Disease._--The coffee industry in Ceylon was ruined by the attack of a fungoid disease (_Hemileia vastatrix_) known as the Ceylon coffee-leaf disease. This has since extended its ravages into every coffee-producing country in the Old World, and added greatly to the difficulties of successful cultivation. The fungus is a microscopic one, the minute spores of which, carried by the wind, settle and germinate upon the leaves of the plant. The fungal growth spreads through the substance to the leaf, robbing the leaf of its nourishment and causing it to wither and fall. An infected plantation may be cleansed, and the fungus in its nascent state destroyed, by powdering the trees with a mixture of lime and sulphur, but, unless the access of fresh spores brought by the wind can be arrested, the plantations may be readily reinfected when the lime and sulphur are washed off by rain. The separation of plantations by belts of trees to windward is suggested as a check to the spread of the disease.

_Microscopic Structure._--Raw coffee seeds are tough and horny in structure, and are devoid of the peculiar aroma and taste which are so characteristic of the roasted seeds. The minute structure of coffee allows it to be readily recognized by means of the microscope, and as roasting does not destroy its distinguishing peculiarities, microscopic examination forms the readiest means of determining the genuineness of any sample. The substance of the seed, according to Dr Hassall, consists "of an assemblage of vesicles or cells of an angular form, which adhere so firmly together that they break up into pieces rather than separate into distinct and perfect cells. The cavities of the cells include, in the form of little drops, a considerable quantity of aromatic volatile oil, on the presence of which the fragrance and many of the active principles of the berry depend" (see fig. 3).

_Physiological Action._--Coffee belongs to the medicinal or auxiliary class of food substances, being solely valuable for its stimulant effect upon the nervous and vascular system. It produces a feeling of buoyancy and exhilaration comparable to a certain stage of alcoholic intoxication, but which does not end in depression or collapse. It increases the frequency of the pulse, lightens the sensation of fatigue, and it sustains the strength under prolonged and severe muscular exertion. The value of its hot infusion under the rigours of Arctic cold has been demonstrated in the experience of all Arctic explorers, and it is scarcely less useful in tropical regions, where it beneficially stimulates the action of the skin.

The physiological action of coffee mainly depends on the presence of the alkaloid caffeine, which occurs also in tea, Paraguay tea, and cola nuts, and is very similar to theobromine, the active principle in cocoa. The percentage of caffeine present varies in the different species of _Coffea_. In Arabian coffee it ranges from about 0.7 to 1.6%; in Liberian coffee from 1.0 to 1.5%. Sierra Leone coffee (_C. stenophylla_) contains from 1.52 to 1.70%; in _C. excelsa_ 1.89% is recorded, and as much as 1.97% in _C. canephora_. Four species have been shown by M. G. Bertrand to contain no caffeine at all, but instead a considerable quantity of a bitter principle. All these four species are found only in Madagascar or the neighbouring islands. Other coffees grown there contain caffeine as usual. Coffee, with the caffeine extracted, has also been recently prepared for the market. The commercial value of coffee is determined by the amount of the aromatic oil, caffeone, which develops in it by the process of roasting. By prolonged keeping it is found that the richness of any seeds in this peculiar oil is increased, and with increased aroma the coffee also yields a blander and more mellow beverage. Stored coffee loses weight at first with great rapidity, as much as 8% having been found to dissipate in the first year of keeping, 5% in the second, and 2% in the third; but such loss of weight is more than compensated by improvement in quality and consequent enhancement of value.

_Roasting._--In the process of roasting, coffee seeds swell up by the liberation of gases within their substance,--their weight decreasing in proportion to the extent to which the operation is carried. Roasting also develops with the aromatic caffeone above alluded to a bitter soluble principle, and it liberates a portion of the caffeine from its combination with the caffetannic acid. Roasting is an operation of the greatest nicety, and one, moreover, of a crucial nature, for equally by insufficient and by excessive roasting much of the aroma of the coffee is lost; and its infusion is neither agreeable to the palate nor exhilarating in its influence. The roaster must judge of the amount of heat required for the adequate roasting of different qualities, and while that is variable, the range of roasting temperature proper for individual kinds is only narrow. In continental countries it is the practice to roast in small quantities, and thus the whole charge is well under the control of the roaster; but in Britain large roasts are the rule, in dealing with which much difficulty is experienced in producing uniform torrefaction, and in stopping the process at the proper moment. The coffee-roasting apparatus is usually a malleable iron cylinder mounted to revolve over the fire on a hollow axle which allows the escape of gases generated during torrefaction. The roasting of coffee should be done as short a time as practicable before the grinding for use, and as ground coffee especially parts rapidly with its aroma, the grinding should only be done when coffee is about to be prepared.

_Adulteration._--Although by microscopic, physical and chemical tests the purity of coffee can be determined with perfect certainty, yet ground coffee is subjected to many and extensive adulterations (see also ADULTERATION). Chief among the adulterant substances, if it can be so called, is chicory; but it occupies a peculiar position, since very many people on the European continent as well as in Great Britain deliberately prefer a mixture of chicory with coffee to pure coffee. Chicory is indeed destitute of the stimulant alkaloid and essential oil for which coffee is valued; but the facts that it has stood the test of prolonged and extended use, and that its infusion is, in some localities, used alone, indicate that it performs some useful function in connexion with coffee, as used at least by Western communities. For one thing, it yields a copious amount of soluble matter in infusion with hot water, and thus gives a specious appearance of strength and substance to what may be really only a very weak preparation of coffee. The mixture of chicory with coffee is easily detected by the microscope, the structure of both, which they retain after torrefaction, being very characteristic and distinct. The granules of coffee, moreover, remain hard and angular when mixed with water, to which they communicate but little colour; chicory, on the other hand, swelling up and softening, yields a deep brown colour to water in which it is thrown. The specific gravity of an infusion of chicory is also much higher than that of coffee. Among the numerous other substances used to adulterate coffee are roasted and ground roots of the dandelion, carrot, parsnip and beet; beans, lupins and other leguminous seeds; wheat, rice and various cereal grains; the seeds of the broom, fenugreek and iris; acorns; "negro coffee," the seeds of _Cassia occidentalis_, the seeds of the ochro (_Hibiscus esculentus_), and also the soja or soy bean (_Glycine Soya_). Not only have these with many more similar substances been used as adulterants, but under various high-sounding names several of them have been introduced as substitutes for coffee; but they have neither merited nor obtained any success, and their sole effect has been to bring coffee into undeserved disrepute with the public.

Not only is ground coffee adulterated, but such mixtures as flour, chicory and coffee, or even bran and molasses, have been made up to simulate coffee beans and sold as such.

The leaves of the coffee tree contain caffeine in larger proportion than the seeds themselves, and their use as a substitute for tea has frequently been suggested. The leaves are actually so used in Sumatra, but being destitute of any attractive aroma such as is possessed by both tea and coffee, the infusion is not palatable. It is, moreover, not practicable to obtain both seeds and leaves from the same plant, and as the commercial demand is for the seed alone, no consideration either of profit or of any dietetic or economic advantage is likely to lead to the growth of coffee trees on account of their leaves.

COFFER (Fr. _coffre_, O. Fr. _cofre_ or _cofne_, Lat. _cophinus_, cf. "coffin"), in architecture, a sunk panel in a ceiling or vault; also a casket or chest in which jewels or precious goods were kept, and, if of large dimensions, clothes. The marriage coffers in Italy were of exceptional richness in their carving and gilding and were sometimes painted by great artists.

COFFERDAM, in engineering. To enable foundations (q.v.) to be laid in a site which is under water, the engineer sometimes surrounds it with an embankment or dam, known as a cofferdam, to form an enclosure from which the water is excluded. Where the depth of water is small and the current slight, simple clay dams may be used, but in general cofferdams consist of two rows of piles, the space between which is packed with clay puddle. The dam must be sufficiently strong to withstand the exterior pressure to which it is exposed when the enclosed space is pumped dry.

COFFEYVILLE, a city of Montgomery county, Kansas, U.S.A., on the Verdigris river, about 150 m. S. of Topeka and near the southern boundary of the state. Pop. (1890) 2282; (1900) 4953, of whom 803 were negroes; (1905) 13,196; (1910) 12,687. Coffeyville is served by the Missouri Pacific, the Atchison, Topeka & Santa Fé, the Missouri, Kansas & Texas, and the Saint Louis, Iron Mountain & Southern railways, and by inter-urban electric railway to Independence. It is in the Kansas natural-gas field, ships large quantities of grain, and has a large zinc oxide smelter and a large oil refinery, and various manufactures, including vitrified brick and tile, flour, lumber, chemicals, window glass, bottles, pottery and straw boards. The municipality owns and operates its water-works and electric lighting plant. Coffeyville, named in honour of A. M. Coffey, who was a member of the first legislature of the territory of Kansas, was founded in 1869, but in 1871 it was removed about 1 m. from its original site, now known as "old town." It was incorporated as a city of the third class in 1872 and received a new charter in 1887. Coffeyville became a station on the Leavenworth, Lawrence & Galveston railway (now part of the Atchison, Topeka & Santa Fé), and for several years large numbers of cattle were driven here from Indian Territory and Texas for shipment; in fact, the city's chief importance was as a trade centre for the north part of Indian Territory until natural gas was found here in large quantities in 1892.

COFFIN (from Lat. _cophinus_, Gr. [Greek: kophinos], a coffer, chest or basket, but never meaning "coffin" in its present sense), the receptacle in which a corpse is confined. The Greeks and Romans disposed of their dead both by burial and by cremation. Greek coffins varied in shape, being in the form of an urn, or like the modern coffins, or triangular, the body being in a sitting posture. The material used was generally burnt clay, and in some cases this had obviously been first moulded round the body, and so baked. Cremation was the commonest method of disposing of the dead among the Romans, until the Christian era, when stone coffins came into use. Examples of these have been frequently dug up in England. In 1853, during excavations for the foundations of some warehouses in Hayden Square, Minories, London, a Roman stone coffin was found within which was a leaden shell. Others have been found at Whitechapel, Stratford-le-Bow, Old Kent Road and Battersea Fields, and in great numbers at Colchester, York, Southfleet and Kingsholme near Gloucester. In early England stone coffins were only used by the nobles and the wealthy. Those of the Romans who were rich enough had their coffins made of a limestone brought from Assos in Troas, which it was commonly believed "ate the body"; hence arose the name sarcophagus (q.v.).

The coffins of the Chaldaeans were generally clay urns with the top left open, resembling immense jars. These, too, must have been moulded round the body, as the size of the mouth would not admit of its introduction after the clay was baked. The Egyptian coffins, or sarcophagi, as they have been improperly called, are the largest stone coffins known and are generally highly polished and covered with hieroglyphics, usually a history of the deceased. Mummy chests shaped to the form of the body were also used. These were made of hard wood or _papier mâché_ painted, and like the stone coffins bore hieroglyphics. The Persians, Parthians, Medes and peoples of the Caspian are not known to have had any coffins, their usual custom being to expose the body to be devoured by beasts and birds of prey. Unhewn flat stones were sometimes used by the ancient European peoples to line the grave. One was placed at the bottom, others stood on their edges to form the sides, and a large slab was put on top, thus forming a rude cist. In England after the Roman invasion these rude cists gave place to the stone coffin, and this, though varying much in shape, continued in use until the 16th century.

The most primitive wooden coffin was formed of a tree-trunk split down the centre, and hollowed out. The earliest specimen of this type is in the Copenhagen museum, the implements found in it proving that it belonged to the Bronze Age. This type of coffin, more or less modified by planing, was used in medieval Britain by those of the better classes who could not afford stone, but the poor were buried without coffins, wrapped simply in cloth or even covered only with hay and flowers. Towards the end of the 17th century, coffins became usual for all classes. It is worth noting that in the Burial Service in the Book of Common Prayer the word "coffin" is not used.

Among the American Indians some tribes, e.g. the Sacs, Foxes and Sioux, used rough hewn wooden coffins; others, such as the Seris, sometimes enclosed the corpse between the carapace and plastron of a turtle. The Seminoles of Florida used no coffins, while at Santa Barbara, California, canoes containing corpses have been found buried though they may have been intended for the dead warrior's use in the next world. Rough stone cists, too, have been found, especially in Illinois and Kentucky. In their tree and scaffold burial the Indians sometimes used wooden coffins, but oftener the bodies were simply wrapped in blankets. Canoes mounted on a scaffold near a river were used as coffins by some tribes, while others placed the corpse in a canoe or wicker basket and floated them out into the stream or lake (see FUNERAL RITES). The aborigines of Australia generally used coffins of bark, but some tribes employed baskets of wicker-work.

Lead coffins were used in Europe in the middle ages, shaped like the mummy chests of ancient Egypt. Iron coffins were more rare, but they were certainly used in England and Scotland as late as the 17th century, when an order was made that upon bodies so buried a heavier burial fee should be levied. The coffins used in England to-day are generally of elm or oak lined with lead, or with a leaden shell so as to delay as far as possible the process of disintegration and decomposition. In America glass is sometimes used for the lids, and the inside is lined with copper or zinc. The coffins of France and Germany and the continent generally, usually differ from those of England in not being of the ordinary hexagonal shape but having sides and ends parallel. Coffins used in cremation throughout the civilized world are of some light material easily consumed and yielding little ash. Ordinary thin deal and _papier mâché_ are the favourite materials. Coffins for what is known as Earth to Earth Burial are made of wicker-work covered with a thin layer of _papier mâché_ over cloth.

COG. (1) (From an older _cogge_, a word which appears in various forms in Teutonic languages, as in O. Ger. _kogge_ or _kocke_, and also in Romanic, as in O. Fr. _cogue_, or _coque_, from which the Eng. "cock-boat" is derived; the connexion between the Teutonic and the Romanic forms is obscure), a broadly built, round-shaped ship, used as a trader and also as a ship of war till the 15th century. (2) (A word of obscure origin, possibly connected with Fr. _coche_, and Ital. _cocca_, a notch; the Celtic forms _cog_ and _cocas_ come from the English), a tooth in a series of teeth, morticed on to, or cut out of the circumference of a wheel, which works with the tooth in a corresponding series on another wheel (see MECHANICS). (3) (Also of quite obscure origin), a slang term for a form of cheating at dice. The early uses of the word show that this was done not by "loading" the dice, as the modern use of the expression of "cogged dice" seems to imply, but by sleight of hand in directing the fall or in changing the dice.

COGERS HALL, a London tavern debating society. It was instituted in 1755 at the White Bear Inn (now St Bride's Tavern), Fleet Street, moved about 1850 to Discussion Hall, Shoe Lane, and in 1871 finally migrated to the Barley Mow Inn, Salisbury Square, E.C., its present quarters. The name is often wrongly spelt Codgers and Coggers; the "o" is really long, the accepted derivation being from Descartes' _Cogito, ergo sum_, and thus meaning "The society of thinkers." The aims of the Cogers were "the promotion of the liberty of the subject and the freedom of the Press, the maintenance of loyalty to the laws, the rights and claims of humanity and the practice of public and private virtue." Among its early members Cogers Hall reckoned John Wilkes, one of its first presidents, and Curran, who in 1773 writes to a friend that he spent a couple of hours every night at the Hall. Later Dickens was a prominent member.

COGHLAN, CHARLES FRANCIS (1841-1899), Irish actor, was born in Paris, and was educated for the law. He made his first London appearance in 1860, and became the leading actor at the Prince of Wales's. He went to America in 1876, where he remained for the rest of his life, playing first in Augustin Daly's company and then in the Union Square stock company, during the long run of _The Celebrated Case_. He also played with his sister, and in support of Mrs Langtry and Mrs Fiske, and in 1898 produced a version of Dumas' _Kean_, called _The Royal Box_, in which he successfully starred during the last years of his life. He died in Galveston, Texas, on the 27th of November 1899.

His sister, the actress ROSE COGHLAN (1853- ), went to America in 1871, was again in England from 1873 to 1877, playing with Barry Sullivan, and then returned to America, where she became prominent as Countess Zicka in _Diplomacy_, and Stephanie in _Forget-me-not_. She was at Wallack's almost continuously until 1888, and subsequently appeared in melodrama in parts like the title-rôle of _The Sporting Duchess_.

COGNAC, a town of south-western France, capital of an arrondissement in the department of Charente, on the left bank of the river Charente, 32 m. W. of Angoulême on the Ouest-État railway, between Angoulême and Saintes. Pop. (1906) 18,389. The streets of the old town--which borders the river--are narrow and tortuous, but the newer parts are well provided with open spaces. The chief of these is the beautiful Parc François 1er overlooking the Charente. In one of the squares there is a statue of Francis I., who was born here. The chief building is a church of the 12th century dedicated to St Leger, which preserves a fine Romanesque façade and a tower of the 15th century. A castle of the 15th and 16th centuries, once the residence of the counts of Angoulême, now a storehouse for brandy, and a medieval gate stand in the older part of the town. Cognac is the seat of a subprefect and has tribunals of first instance and of commerce, a council of trade arbitrators, a chamber of commerce, and consulates of the United States, Spain and Portugal. Its most important industry is the distillation of the brandy (q.v.) to which the town gives its name. Large quantities are carried, by way of the river, to the neighbouring port of Tonnay-Charente. The industries subsidiary to the brandy trade, such as the making of cases and bottles, occupy many hands. Ironware is also manufactured, and a considerable trade is maintained in grain and cattle. In 1526 Cognac gave its name to a treaty concluded against Charles V. by Francis I., the pope, Venice and Milan. Its possession was contested during the wars of religion, and in 1570 it became one of the Huguenot strongholds. In 1651 it successfully sustained a siege against Louis II., prince of Condé, leader of the Fronde.

See _Le Pays du Cognac_, by L. Ravaz, for a description of the district and its viticulture.

COGNITION (Latin _cognitio_, from _cognoscere_, to become acquainted with), in psychology, a term used in its most general sense for all modes of being conscious or aware of an object, whether material or intellectual. It is an ultimate mode of consciousness, strictly the presentation (through sensation or otherwise) of an object to consciousness; in its complete form, however, it seems to involve a judgment, i.e. the separation from other objects of the object presented. The psychological theory of cognition takes for granted the dualism of the mind that knows and the object known; it takes no account of the metaphysical problem as to the possibility of a relation between the ego and the non-ego, but assumes that such a relation does exist. Cognition is therefore distinct from emotion and conation; it has no psychological connexion with feelings of pleasure and pain, nor does it tend as such to issue in action.

For the analysis of cognition-reactions see O. Külpe, _Outlines of Psychology_ (Eng. trans., 1895), pp. 411 foll.; E. B. Titchener, _Experimental Psychology_ (1905), ii. 187 foll. On cognition generally, G. F. Stout's _Analytic Psychology and Manual of Psychology_; W. James's _Principles of Psychology_ (1890), i. 216 foll.; also article PSYCHOLOGY.

COGNIZANCE (Lat. _cognoscere_, to know), knowledge, notice, especially judicial notice, the right of trying or considering a case judicially, the exercise of jurisdiction by a court of law. In heraldry a "cognizance" is an emblem, badge or device, used as a distinguishing mark by the body of retainers of a royal or noble house.

COHEN (Hebrew for "priest"), a Jewish family name, implying descent from the ancient Hebrew priests. Many families claiming such descent are, however, not named Cohen. Other forms of the name are Cohn, Cowen, Kahn.

See J. Jacobs, _Jewish Encyclopedia_, iv. 144.

COHN, FERDINAND JULIUS (1828-1898), German botanist, was born on the 24th of January 1828 at Breslau. He was educated at Breslau and Berlin, and in 1859 became extraordinary, and in 1871 ordinary, professor of botany at Breslau University. He had a remarkable career, owing to his Jewish origin. He was contemporary with N. Pringsheim, and worked with H. R. Goeppert, C. G. Nees von Esenbeck, C. G. Ehrenberg and Johannes Müller. At an early date he exhibited astonishing ability with the microscope, which he did much to improve, and his researches on cell-walls and the growth and contents of plant-cells soon attracted attention, especially as he made remarkable advances in the establishment of an improved cell-theory, discovered the cilia in, and analysed the movements of, zoospores, and pointed out that the protoplasm of the plant-cell and the sarcode of the zoologists were one and the same physical vehicle of life. Although these early researches were especially on the Algae, in which group he instituted marked reforms of the rigid system due to F. T. Kützing, Cohn had already displayed that activity in various departments which made him so famous as an all-round naturalist, his attention at various times being turned to such varied subjects as _Aldorovanda_, torsion in trees, the nature of waterspouts, the effects of lightning, physiology of seeds, the proteid crystals in the potato, which he discovered, the formation of travertin, the rotatoria, luminous worms, &c.

It is, however, in the introduction of the strict biological and philosophical analysis of the life-histories of the lower and most minute forms of life that Cohn's greatest achievements consist, for he applied to these organisms the principle that we can only know the phases of growth of microscopic plants by watching every stage of development under the microscope, just as we learn how different are the youthful and adult appearances of an oak or a fern by direct observation. The success with which he attempted and carried out the application of cultural and developmental methods on the Algae, Fungi and Bacteria can only be fully appreciated by those familiar with the minute size and elusive evolutions of these organisms, and with the limited appliances at Cohn's command. Nevertheless his account of the life-histories of _Protococcus_ (1850), _Stephanosphaera_ (1852), _Volvox_ (1856 and 1875), _Hydrodictyon_ (1861), and _Sphaeroplea_ (1855-1857) among the Algae have never been put aside. The first is a model of what a study in development should be; the last shares with G. Thuret's studies on _Fucus_ and Pringsheim's on _Vaucheria_ the merit of establishing the existence of a sexual process in Algae. Among the Fungi Cohn contributed important researches on _Pilobolus_ (1851), _Empusa_ (1855), _Tarichium_ (1869), as well as valuable work on the nature of parasitism of Algae and Fungi.

It is as the founder of bacteriology that Cohn's most striking claims to recognition will be established. He seems to have been always attracted particularly by curious problems of fermentation and coloration due to the most minute forms of life, as evinced by his papers on _Monas prodigiosa_ (1850) and "Über blutähnliche Färbungen" (1850), on infusoria (1851 and 1852), on organisms in drinking-water (1853), "Die Wunder des Blutes" (1854), and had already published several works on insect epidemics (1869-1870) and on plant diseases, when his first specially bacteriological memoir (_Crenothrix_) appeared in the journal, _Beiträge zur Biologie_, which he then started (1870-1871), and which has since become so renowned. Investigations on other branches of bacteriology soon followed, among which "Organismen der Pockenlymphe" (1872) and "Untersuchungen über Bacterien" (1872-1875) are most important, and laid the foundations of the new department of science which has now its own laboratories, literature and workers specially devoted to its extension in all directions. When it is remembered that Cohn brought out and helped R. Koch in publishing his celebrated paper on _Anthrax_ (1876), the first clearly worked out case of a bacterial disease, the significance of his influence on bacteriology becomes apparent.

Among his most striking discoveries during his studies of the forms and movements of the Bacteria may be mentioned the nature of Zoogloea, the formation and germination of true spores--which he observed for the first time, and which he himself discovered in _Bacillus subtilis_--and their resistance to high temperatures, and the bearing of this on the fallacious experiments supposed to support abiogenesis; as well as works on the bacteria of air and water, the significance of the bright sulphur granules in sulphur bacteria, and of the iron oxide deposited in the walls of _Crenothrix_. His discoveries in these and in other departments all stand forth as mementoes of his acute observation and reasoning powers, and the thoughtful (in every sense of the word) consideration of the work of others, and suggestive ideas attached to his principal papers, bear the same characteristics. If we overcome the always difficult task of bridging in imagination the interval between our present platform of knowledge and that on which bacteriologists stood in, say, 1870, we shall not undervalue the important contributions of Cohn to the overthrow of the then formidable bugbear known as the doctrine of "spontaneous generation," a dogma of despair calculated to impede progress as much in its day as that of "vitalism" did in other periods. Cohn had also clear perceptions of the important bearings of Mycology and Bacteriology in infective diseases, as shown by his studies in insect-killing fungi, microscopic analysis of water, &c. He was a foreign member of the Royal Society and of the Linnean Society, and received the gold medal of the latter in 1895. He died at Breslau on the 25th of June 1898.

Lists of his papers will be found in the _Catalogue of Scientific Papers of the Royal Society_, and in _Ber. d. d. bot. Gesellsch._, 1899, vol. xvii. p. (196). The latter also contains (p. (172)) a full memoir by F. Rosen. (H. M. W.)

COHN, GUSTAV (1840- ), German economist, was born on the 12th of December 1840 at Marienwerder, in West Prussia. He was educated at Berlin and Jena universities. In 1869 he obtained a post at the polytechnic in Riga, and in 1875 was elected a professor at the polytechnic at Zürich. In 1873 he went to England for a period of study, and as a result published his _Untersuchungen über die englische Eisenbahnpolitik_ (Leipzig, 1874-1875). In 1884 he was appointed professor of political science at Göttingen. Cohn's best-known works are _System der Nationalökonomie_ (Stuttgart, 1885); _Finanzwissenschaft_ (1889); _Nationalökonomische Studien_ (1886), and _Zur Geschichte und Politik des Verkehrswesens_ (1900).

COHOES, a city of Albany county, New York, U.S.A., about 9 m. N. of Albany, at the confluence of the Mohawk and Hudson rivers. Pop. (1890) 22,509; (1900) 23,910, of whom 7303 were foreign-born; (1910) 24,709. It is served by the New York Central & Hudson River and the Delaware & Hudson railways, by electric lines to Troy and Albany, and by the Erie and Champlain canals. It is primarily a manufacturing city. Hosiery and knit goods, cotton cloth, cotton batting, shoddy, underwear and shirts and collars are the principal products, but there are also extensive valve works and manufactories of pulp, paper and paper boxes, beer, pins and needles, tools and machinery, and sash, doors and blinds. The value of the factory products in 1905 was $10,289,822, of which $4,126,873, or 40.1%, was the value of hosiery and knit goods, Cohoes ranking fifth among the cities of the United States (of 20,000 inhabitants or more) in this industry, and showing a higher degree of specialization in it than any other city in the United States except Little Falls, N.Y. The Falls of the Mohawk, which furnish power for the majority of the manufacturing establishments, are 75 ft. high and 900 ft. broad, a large dam above the falls storing the water, which is conveyed through canals to the mills. Below the falls the river is crossed by two fine iron bridges. The city has a public library, a normal training school and the St Bernard's (Roman Catholic) Academy. Cohoes was a part of the extensive manorial grant made to Killian Van Rensselaer in 1629 and it was probably settled very soon afterwards. It was incorporated as a village in 1848 and was chartered as a city in 1870.

COHORT (Lat. _cohors_), originally a place enclosed: in the Roman army, the name of a unit of infantry. The troops of the first grade, the legions, were divided into cohorts, of which there were ten in each legion: the cohort thus contained 600 men. Among the troops of the second grade (the _auxilia_) the cohorts were independent foot regiments 500 or 1000 strong, corresponding to the _alae_, which were similar regiments of cavalry; they were generally posted on the frontiers of the Empire in small forts of four to eight acres, each holding one cohort or _ala_. The special troops of Rome itself, the Praetorian Guard, the Urbanae Cohortes, and the Vigiles (fire brigade), were divided into cohorts (see further ROMAN ARMY). The phrase _cohors praetoria_ or _cohors amicorum_ was sometimes used, especially during the Roman republic, to denote the suite of the governor of a province; hence developed the Praetorian cohorts which formed the emperor's bodyguard.

In biology, "cohort" is a term for a group of allied orders or families of plants or animals.

COIF (from Fr. _coiffe_, Ital. _cuffia_, a cap), a close-fitting covering for the head. Originally it was the name given to a head-covering worn in the middle ages, tied like a night-cap under the chin, and worn out of doors by both sexes; this was later worn by men as a kind of night-cap or skull-cap. The coif was also a close-fitting cap of white lawn or silk, worn by English serjeants-at-law as a distinguishing mark of their profession. It became the fashion to wear on the top of the white coif a small skull-cap of black silk or velvet; and on the introduction of wigs at the end of the 17th century a round space was left on the top of the wig for the display of the coif, which was afterwards covered by a small patch of black silk edged with white (see A. Pulling, _Order of the Coif_, 1897). The random conjecture of Sir H. Spelman (_Glossarium archaiologicum_) that the coif was originally designed to conceal the ecclesiastical tonsure has unfortunately been quoted by annotators of Blackstone's _Commentaries_ as well as by Lord Campbell in his _Lives of the Chief Justices_. It may be classed with the curious conceit, recorded in Brand's _Popular Antiquities_, that the coif was derived from the child's caul, and was worn on the advocate's head for luck.

COIMBATORE, a city and district of British India, in the Madras presidency. The city is situated on the left bank of the Noyil river, 305 m. from Madras by the Madras railway. In 1901 it had a population of 53,080, showing an increase of 14% in the decade. The city stands 1437 ft. above sea-level, is well laid out and healthy, and is rendered additionally attractive to European residents by its picturesque position on the slopes of the Nilgiri hills. It is an important industrial centre, carrying on cotton weaving and spinning, tanning, distilling, and the manufacture of coffee, sugar, manure and saltpetre. It has two second-grade colleges, a college of agriculture, and a school of forestry.

The DISTRICT OF COIMBATORE has an area of 7860 sq. m. It may be described as a flat, open country, hemmed in by mountains on the north, west and south, but opening eastwards on to the great plain of the Carnatic; the average height of the plain above sea-level is about 900 ft. The principal mountains are the Anamalai Hills, in the south of the district, rising at places to a height of between 8000 and 9000 ft. In the west the Palghat and Vallagiri Hills form a connecting link between the Anamalai range and the Nilgiris, with the exception of a remarkable gap known as the Palghat Pass. This gap, which completely intersects the Ghats, is about 20 m. wide. In the north is a range of primitive trap-hills known as the Cauvery chain, extending eastwards from the Nilgiris, and rising in places to a height of 4000 ft. The principal rivers are the Cauvery, Bhavani, Noyil, and Amravati. Numerous canals are cut from the rivers for the purpose of affording artificial irrigation, which has proved of immense benefit to the country. Well and tank water is also largely used for irrigation purposes. Coimbatore district was acquired by the British in 1799 at the close of the war which ended with the death of Tippoo. In 1901 the population was 2,201,782, showing an increase of 10% in the preceding decade. The principal crops are millet, rice, other food grains, pulse, oilseeds, cotton and tobacco, with a little coffee. Forests cover nearly 1½ million acres, yielding valuable timber (teak, sandalwood, &c.), and affording grazing-ground for cattle. There are several factories for pressing cotton, and for cleaning coffee, oil-cake presses, tanneries and saltpetre refineries. Cereals, cotton, forest products, cattle and hides, and brass and copper vessels are the chief exports from the district. The south-west line of the Madras railway runs through the district, and the South Indian railway (of metre gauge) joins this at Erode.

COIMBRA, the capital of an administrative district formerly included in the province of Beira, Portugal; on the north bank of the river Mondego, 115 m. N.N.E. of Lisbon, on the Lisbon-Oporto railway. Pop. (1900) 18,144. Coimbra is built for the most part on rising ground, and presents from the other side of the river a picturesque and imposing appearance; though in reality its houses have individually but little pretension, and its streets are, almost without exception, narrow and mean. It derives its present importance from being the seat of the only university in the kingdom--an institution which was originally established at Lisbon in 1291, was transferred to Coimbra in 1306, was again removed to Lisbon, and was finally fixed at Coimbra in 1527. There are five faculties--theology, law, medicine, mathematics and philosophy--with more than 1300 students. The library contains about 150,000 volumes, and the museums and laboratories are on an extensive scale. In connexion with the medical faculty there are regular hospitals; the mathematical faculty maintains an observatory from which an excellent view can be obtained of the whole valley of the Mondego; and outside the town there is a botanic garden (especially rich in the flora of Brazil), which also serves as a public promenade. Among the other educational establishments are a military college, a royal college of arts, a scientific and literary institute, and an episcopal seminary.

The city is the seat of a bishop, suffragan to the archbishop of Braga; its new cathedral, founded in 1580, is of little interest; but the old is a fine specimen of 12th-century Romanesque, and retains portions of the mosque which it replaced. The principal churches are Santa Cruz, of the 16th century, and San Salvador, founded in 1169. On the north bank of the Mondego stand the ruins of the once splendid monastery of Santa Clara, established in 1286; and on the south bank is the celebrated _Quinta das lagrimas_, or Villa of Tears, where Inez de Castro (q.v.) is believed to have been murdered in 1355. The town is supplied with water by means of an aqueduct of 20 arches. The Mondego is only navigable in flood, and the port of Figueira da Foz is 20 m. W. by S., so that the trade of Coimbra is mainly local; but there are important lamprey fisheries and manufactures of pottery, leather and hats.

A Latin inscription of the 4th century identifies Coimbra with the ancient Aeminium; while Condeixa (3623), 8 m. S.S.W., represents the ancient Conimbriga or Conembrica,. In the 9th century, however, when the bishopric of Conimbriga was removed hither, its old title was transferred to the new see, and hence arose the modern name Coimbra. The city was for a long time a Moorish stronghold, but in 1064 it was captured by Ferdinand I. of Castile and the Cid. Until 1260 it was the capital of the country, and no fewer than six kings--Sancho I. and II., Alphonso II. and III., Pedro and Ferdinand--were born within its walls. It was also the birthplace of the poet Francisco Sá de Miranda (1495-1558), and, according to one tradition, of the more famous Luiz de Camoens (1524-1580), who was a student at the university between 1537 and 1542. In 1755 Coimbra suffered considerably from the earthquake. In 1810 it was sacked by the French under Marshal Masséna. In 1834 Dom Miguel made the city his headquarters; and in 1846 it was the scene of a Miguelist insurrection.

The administrative district of Coimbra coincides with the south-western part of Beira; pop. (1900) 332,168; area 1508 sq. m.

COÍN, a town of southern Spain in the province of Málaga; 18 m. W.S.W. of the city of Málaga. Pop. (1900) 12,326. Coín is finely situated on the northern slope of the Sierra de Mijas, overlooking the small river Séco and surrounded by vineyards and plantations of oranges and lemons. There are marble quarries in the neighbourhood, and, despite the lack of a railway, Coín has a thriving agricultural trade. The population increased by more than half between 1880 and 1900.

COIN (older forms of the word are _coyne_, _quoin_ and _coign_, all derived through the O. Fr. _coing_, and _cuigne_ from Lat. _cuneus_, a wedge), properly the term for a wedge-shaped die used for stamping money, and so transferred to the money so stamped; hence a piece of money. The form "quoin" is used for the external angle of a building (see QUOINS), and "coign," also a projecting angle, survives in the Shakespearean phrase "a coign of vantage."

COINAGE OFFENCES. The coinage of money is in all states a prerogative of the sovereign power; consequently any infringement of that prerogative is always severely punished, as being an offence likely to interfere with the well-being of the state.

In the United Kingdom the statute law against offences relating to the coin was codified by an act of 1861. The statute provides that whoever falsely makes or counterfeits any coin resembling or apparently intended to resemble or pass for any current gold or silver coin of the realm (s. 2), or gilds, silvers, washes, cases over or colours with materials capable of producing the appearance of gold or silver a coin or a piece of any metal or mixture of metals, or files or alters it, with intent to make it resemble or pass for any current gold or silver coin (s. 3), or who buys, sells, receives or pays a false gold or silver coin at a lower rate than its denomination imports, or who receives into the United Kingdom any false coin knowing it to be counterfeit (ss. 6, 7), or who, without lawful authority or excuse, knowingly makes or mends, buys or sells, or has in his custody or possession, or conveys out of the Royal Mint any coining moulds, machines or tools, is guilty of felony (ss. 24, 25). The punishment for such offences is either penal servitude for life or for not less than three years, or imprisonment for not more than two years, with or without hard labour. Whoever impairs, diminishes or lightens current gold or silver coin, with intent to pass same, is liable to penal servitude for from three to fourteen years (s. 4), and whoever has in his possession filings or clippings obtained by impairing or lightening current coin is liable to the same punishment, or to penal servitude for from three to seven years. The statute also makes provision against tendering or uttering false gold or silver coin, which is a misdemeanour, punishable by imprisonment with or without hard labour. Provision is also made with respect to falsely making, counterfeiting, tendering or uttering copper coin, exporting false coin, or defacing current coin by stamping names or words on it, and counterfeiting, tendering or uttering coin resembling or meant to pass as that of some foreign state. The act of 1861 applies to offences with respect to colonial coins as well as to those of the United Kingdom.

By the constitution of the United States, Congress has the power of coining money, regulating the value thereof and of foreign coin (Art. i. s. viii.), and the states are prohibited from coining money, or making anything but gold and silver money a tender in payment of debts (Art. i. s. x.). The counterfeiting coin or money, uttering the same, or mutilating or defacing it, is an offence against the United States, and is punishable by fine and imprisonment with hard labour for from two to ten years. It has also been made punishable by state legislation.

COIR (from Malay _K[=a]yar_, cord, _K[=a]yaru_, to be twisted), a rough, strong, fibrous substance obtained from the outer husk of the coco-nut. (See COCO-NUT PALM.)

COIRE (Ger. _Chur_ or _Cur_, Ital. _Coira_, Lat. _Curia Raetorum_, Romonsch _Cuera_), the capital of the Swiss canton of the Grisons. It is built, at a height of 1949 ft. above the sea-level, on the right bank of the Plessur torrent, just as it issues from the Schanfigg valley, and about a mile above its junction with the Rhine. It is overshadowed by the Mittenberg (east) and Pizokel (south), hills that guard the entrance to the deep-cut Schanfigg valley. In 1900 it contained 11,532 inhabitants, of whom 9288 were German-speaking, 1466 Romonsch-speaking, and 677 Italian-speaking; while 7561 were Protestants, 3962 Romanists and one a Jew. The modern part of the city is to the west, but the old portion, with all the historical buildings, is to the east. Here is the cathedral church of St Lucius (who is the patron of Coire, and is supposed to be a 2nd-century British king, though really the name has probably arisen from a confusion between Lucius of Cyrene--miswritten "_curiensis_"--with the Roman general Lucius Munatius Plancus, who conquered Raetia). Built between 1178 and 1282, on the site of an older church, it contains many curious medieval antiquities (especially in the sacristy), as well as a picture by Angelica Kaufmann, and the tomb of the great Grisons political leader (d. 1637) Jenatsch (q.v.). Opposite is the Bishop's Palace, and not far off is the Episcopal Seminary (built on the ruins of a 6th-century monastic foundation). Not far from these ancient monuments is the new Raetian Museum, which contains a great collection of objects relating to Raetia (including the geological collections of the Benedictine monk of Disentis, Placidus a Spescha (1752-1833), who explored the high snowy regions around the sources of the Rhine). One of the hospitals was founded by the famous Capuchin philanthropist, Father Theodosius Florentini (1808-1865), who was long the Romanist curé of Coire, and whose remains were in 1906 transferred from the cathedral here to Ingenbohl (near Schwyz), his chief foundation. Coire is 74 m. by rail from Zürich, and is the meeting-point of the routes from Italy over many Alpine passes (the Lukmanier, the Splügen, the San Bernardino) as well as from the Engadine (Albula, Julier), so that it is the centre of an active trade (particularly in wine from the Valtelline), though it possesses also a few local factories.

The episcopal see is first mentioned in 452, but probably existed a century earlier. The bishop soon acquired great temporal powers, especially after his dominions were made, in 831, dependent on the Empire alone, of which he became a prince in 1170. In 1392 he became head of the league of God's House (originally formed against him in 1367), one of the three Raetian leagues, but, in 1526, after the Reformation, lost his temporal powers, having fulfilled his historical mission (see GRISONS). The bishopric still exists, with jurisdiction over the Cantons of the Grisons, Glarus, Zürich, and the three Forest Cantons, as well as the Austrian principality of Liechtenstein. The gild constitution of the city of Chur lasted from 1465 to 1839, while in 1874 the _Burgergemeinde_ was replaced by an _Einwohnergemeinde_.

COKE, SIR EDWARD (1552-1634), English lawyer, was born at Mileham, in Norfolk, on the 1st of February 1552. From the grammar school of Norwich he passed to Trinity College, Cambridge; and in 1572 he entered Lincoln's Inn. In 1578 he was called to the bar, and in the next year he was chosen reader at Lyon's Inn. His extensive and exact legal erudition, and the skill with which he argued the intricate libel case of Lord Cromwell (4 Rep. 13), and the celebrated real property case of Shelley (1 Rep. 94, 104), soon brought him a practice never before equalled, and caused him to be universally recognized as the greatest lawyer of his day. In 1586 he was made recorder of Norwich, and in 1592 recorder of London, solicitor-general, and reader in the Inner Temple. In 1593 he was returned as member of parliament for his native county, and also chosen speaker of the House of Commons. In 1594 he was promoted to the office of attorney-general, despite the claims of Bacon, who was warmly supported by the earl of Essex. As crown lawyer his treatment of the accused was marked by more than the harshness and violence common in his time; and the fame of the victim has caused his behaviour in the trial of Raleigh to be lastingly remembered against him. While the prisoner defended himself with the calmest dignity and self-possession, Coke burst into the bitterest invective, brutally addressing the great courtier as if he had been a servant, in the phrase, long remembered for its insolence and its utter injustice--"Thou hast an English face, but a Spanish heart!"

In 1582 Coke married the daughter of John Paston, a gentleman of Suffolk, receiving with her a fortune of £30,000; but in six months he was left a widower. Shortly after he sought the hand of Lady Elizabeth Hatton, daughter of Thomas, second Lord Burghley, and granddaughter of the great Cecil. Bacon was again his rival, and again unsuccessfully; the wealthy young widow became--not, it is said, to his future comfort--Coke's second wife.

In 1606 Coke was made chief justice of the common pleas, but in 1613 he was removed to the office of chief justice of the king's bench, which gave him less opportunity of interfering with the court. The change, though it brought promotion in dignity, caused a diminution of income as well as of power; but Coke received some compensation in being appointed a member of the privy council. The independence of his conduct as a judge, though not unmixed with the baser elements of prejudice and vulgar love of authority, has partly earned forgiveness for the harshness which was so prominent in his sturdy character. Full of an extreme reverence for the common law which he knew so well, he defended it alike against the court of chancery, the ecclesiastical courts, and the royal prerogative. In a narrow spirit, and strongly influenced, no doubt, by his enmity to the chancellor, Thomas Egerton (Lord Brackley), he sought to prevent the interference of the court of chancery with even the unjust decisions of the other courts. In the case of an appeal from a sentence given in the king's bench, he advised the victorious, but guilty, party to bring an action of praemunire against all those who had been concerned in the appeal, and his authority was stretched to the utmost to obtain the verdict he desired. On the other hand, Coke has the credit of having repeatedly braved the anger of the king. He freely gave his opinion that the royal proclamation cannot make that an offence which was not an offence before. An equally famous but less satisfactory instance occurred during the trial of Edmund Peacham, a divine in whose study a sermon had been found containing libellous accusations against the king and the government. There was nothing to give colour to the charge of high treason with which he was charged, and the sermon had never been preached or published; yet Peacham was put to the torture, and Bacon was ordered to confer with the judges individually concerning the matter. Coke declared such conference to be illegal, and refused to give an opinion, except in writing, and even then he seems to have said nothing decided. But the most remarkable case of all occurred in the next year (1616). A trial was held before Coke in which one of the counsel denied the validity of a grant made by the king to the bishop of Lichfield of a benefice to be held _in commendam_. James, through Bacon, who was then attorney-general, commanded the chief justice to delay judgment till he himself should discuss the question with the judges. At Coke's request Bacon sent a letter containing the same command to each of the judges, and Coke then obtained their signatures to a paper declaring that the attorney-general's instructions were illegal, and that they were bound to proceed with the case. His Majesty expressed his displeasure, and summoned them before him in the council-chamber, where he insisted on his supreme prerogative, which, he said, ought not to be discussed in ordinary argument. Upon this all the judges fell on their knees, seeking pardon for the form of their letter; but Coke ventured to declare his continued belief in the loyalty of its substance, and when asked if he would in the future delay a case at the king's order, the only reply he would vouchsafe was that he would do what became him as a judge. Soon after he was dismissed from all his offices on the following charges,--the concealment, as attorney-general, of a bond belonging to the king, a charge which could not be proved, illegal interference with the court of chancery and disrespect to the king in the case of commendams. He was also ordered by the council to revise his book of reports, which was said to contain many extravagant opinions (June 1616).

Coke did not suffer these losses with patience. He offered his daughter Frances, then little more than a child, in marriage to Sir John Villiers, brother of the favourite Buckingham. Her mother, supported at first by her husband's great rival and her own former suitor, Bacon, objected to the match, and placed her in concealment. But Coke discovered her hiding-place; and she was forced to wed the man whom she declared that of all others she abhorred. The result was the desertion of the husband and the fall of the wife. It is said, however, that after his daughter's public penance in the Savoy church, Coke had heart enough to receive her back to the home which he had forced her to leave. Almost all that he gained by his heartless diplomacy was a seat in the council and in the star-chamber.

In 1620 a new and more honourable career opened for him. He was elected member of parliament for Liskeard; and henceforth he was one of the most prominent of the constitutional party. It was he who proposed a remonstrance against the growth of popery and the marriage of Prince Charles to the infanta of Spain, and who led the Commons in the decisive step of entering on the journal of the House the famous petition of the 18th of December 1621, insisting on the freedom of parliamentary discussion, and the liberty of speech of every individual member. In consequence, together with Pym and Sir Robert Philips, he was thrown into confinement; and, when in the August of the next year he was released, he was commanded to remain in his house at Stoke Poges during his Majesty's pleasure. Of the first and second parliaments of Charles I. Coke was again a member. From the second he was excluded by being appointed sheriff of Buckinghamshire. In 1628 he was at once returned for both Buckinghamshire and Suffolk, and he took his seat for the former county. After rendering other valuable support to the popular cause, he took a most important part in drawing up the great Petition of Right. The last act of his public career was to bewail with tears the ruin which he declared the duke of Buckingham was bringing upon the country. At the close of the session he retired into private life; and the six years that remained to him were spent in revising and improving the works upon which, at least as much as upon his public career, his fame now rests. He died at Stoke Poges on the 3rd of September 1634.

Coke published _Institutes_ (1628), of which the first is also known as _Coke upon Littleton_; _Reports_ (1600-1615), in thirteen parts; _A Treatise of Bail and Mainprize_ (1635); _The Complete Copyholder_ (1630); _A Reading on Fines and Recoveries_ (1684).

See Johnson, _Life of Sir Edward Coke_ (1837); H. W. Woolrych, _The Life of Sir Edward Coke_ (1826); Foss, _Lives of the Judges_; Campbell, _Lives of the Chief Justices_; also ENGLISH LAW.

COKE, SIR JOHN (1563-1644), English politician, was born on the 5th of March 1563, and was educated at Trinity College, Cambridge. After leaving the university he entered public life as a servant of William Cecil, Lord Burghley, afterwards becoming deputy-treasurer of the navy and then a commissioner of the navy, and being specially commended for his labours on behalf of naval administration. He became member of parliament for Warwick in 1621 and was knighted in 1624, afterwards representing the university of Cambridge. In the parliament of 1625 Coke acted as a secretary of state; in this and later parliaments he introduced the royal requests for money, and defended the foreign policy of Charles I. and Buckingham, and afterwards the actions of the king. His actual appointment as secretary dates from September 1625. Disliked by the leaders of the popular party, his speeches in the House of Commons did not improve the king's position, but when Charles ruled without a parliament he found Coke's industry very useful to him. The secretary retained his post until 1639, when a scapegoat was required to expiate the humiliating treaty of Berwick with the Scots, and the scapegoat was Coke. Dismissed from office, he retired to his estate at Melbourne in Derbyshire, and then resided in London, dying at Tottenham on the 8th of September 1644. Coke's son, Sir John Coke, sided with the parliament in its struggle with the king, and it is possible that in later life Coke's own sympathies were with this party, although in his earlier years he had been a defender of absolute monarchy. Coke, who greatly disliked the papacy, is described by Clarendon as "a man of very narrow education and a narrower mind"; and again he says, "his cardinal perfection was industry and his most eminent infirmity covetousness."

COKE, THOMAS (1747-1814), English divine, the first Methodist bishop, was born at Brecon, where his father was a well-to-do apothecary. He was educated at Jesus College, Oxford, taking the degree of M.A. in 1770 and that of D.C.L. in 1775. From 1772 to 1776 he was curate at South Petherton in Somerset, whence his rector dismissed him for adopting the open-air and cottage services introduced by John Wesley, with whom he had become acquainted. After serving on the London Wesleyan circuit he was in 1782 appointed president of the conference in Ireland, a position which he frequently held, in the intervals of his many voyages to America. He first visited that country in 1784, going to Baltimore as "superintendent" of the Methodist societies in the new world and, in 1787 the American conference changed his title to "bishop," a nomenclature which he tried in vain to introduce into the English conference, of which he was president in 1797 and 1805. Failing this, he asked Lord Liverpool to make him a bishop in India, and he was voyaging to Ceylon when he died on the 3rd of May 1814. Coke had always been a missionary enthusiast, and was the pioneer of such enterprise in his connexion. He was an ardent opponent of slavery, and endeavoured also to heal the breach between the Methodist and Anglican communions. He published a _History of the West Indies_ (3 vols., 1808-1811), several volumes of sermons, and, with Henry Moore, a _Life of Wesley_ (1792).

COKE (a northern English word, possibly connected with "colk," core), the product obtained by strongly heating coal out of contact with the air until the volatile constituents are driven off; it consists essentially of carbon, the so-called "fixed carbon," together with the incombustible matters or ash contained in the coal from which it is derived. In addition to these it almost invariably contains small quantities of hydrogen, oxygen and nitrogen, the whole, however, not exceeding 2 or 3%. It also contains water, the amount of which may vary considerably according to the method of manufacture. When produced rapidly and at a low heat, as in gas-making, it is of a dull black colour, and a loose spongy or pumice-like texture, and ignites with comparative ease, though less readily than bituminous coal, so that it may be burnt in open fire-places; but when a long-continued heat is used, as in the preparation of coke for iron and steel melting, the product is hard and dense, is often prismatic in structure, has a brilliant semi-metallic lustre and silvery-grey colour, is a conductor of heat and electricity, and can only be burnt in furnaces provided with a strong chimney draught or an artificial blast. The strength and cohesive properties are also intimately related to the nature and composition of the coals employed, which are said to be caking or non-caking according to the compact or fragmentary character of the coke produced.

Formerly coke was made from large coal piled in heaps with central chimneys like those of the charcoal burner, or in open rectangular clamps or kilns with air flues in the enclosing walls; but these methods are now practically obsolete, closed chambers or ovens being generally used. These vary considerably in construction, but may be classified into three principal types:--(1) direct heated ovens, (2) flue-heated ovens, (3) condensing ovens. In the first class the heating is done by direct contact or by burning the gases given off in coking within the oven, while in the other two the heating is indirect, the gas being burned in cellular passages or flues provided in the walls dividing the coking chambers, and the heat transmitted through the sides of the latter which are comparatively thin. The arrangement is somewhat similar to that of a gas-works retort, whence the name of "retort ovens" is sometimes applied to them. The difference between the second and third classes is founded on the treatment of the gases. In the former the gas is fired in the side flues immediately upon issuing from the oven, while in the latter the gases are first subjected to a systematic treatment in condensers, similar to those used in gas-works, to remove tar, ammonia and condensable hydrocarbons, the incondensable gases being returned to the oven and burned in the heating flues. These are generally known as "by-product ovens."

Beehive oven.

The simplest form of coke oven, and probably that still most largely used, is the so-called "beehive oven." This is circular in plan, from 7 to 12 ft. in diameter, with a cylindrical wall about 2½ ft. high and a nearly hemispherical roof with a circular hole at the top. The floor, made of refractory bricks or slabs, is laid with a slight slope towards an arched opening in the ring wall, which is stopped with brickwork during the coking but opened for drawing the finished charge. The ovens are usually arranged in rows or banks of 20 to 30 or more, with their doors outwards, two rows being often placed with a longitudinal flue between them connected by uptakes with the individual ovens on either side. A railway along the top of the bank brings the coal from the screens or washery. The largest ovens take a charge of about 5 tons, which is introduced through the hole in the roof, the brickwork of the empty oven being still red hot from the preceding charge, and when levelled fills the cylindrical part nearly to the springing of the roof. The gas fires as it is given off and fills the dome with flame, and the burning is regulated by air admitted through holes in the upper part of the door stopping. The temperature being very high, a proportion of the volatile hydrocarbons is decomposed, and a film of graphitic carbon is deposited on the coke, giving it a semi-metallic lustre and silvery grey colour. When the gas is burned off, the upper part of the door is opened and the glowing charge cooled by jets of water thrown directly upon it from a hose, and it is subsequently drawn out through the open door. The charge breaks up into prisms or columns whose length corresponds to the depth of the charge, and as a rule is uniform in character and free from dull black patches or "black ends." The time of burning is either 48 or 72 hours, the turns being so arranged as to avoid the necessity of drawing the ovens on Sunday. The longer the heat is continued the denser the product becomes, but the yield also diminishes, as a portion of the finished coke necessarily burns to waste when the gas is exhausted. For this reason the yield on the coal charged is usually less than that obtained in retort ovens, although the quality may be better. Coals containing at most about 35% of volatile matter are best suited for the beehive oven. With less than 25% the gas is not sufficient to effect the coking completely, and when there is a higher percentage the coke is brittle and spongy and unsuited for blast furnace or foundry use. The spent flame from the ovens passes to a range of steam boilers before escaping by the chimney.

Retort oven.

The retort oven, which is now generally displacing the beehive form in new installations, is made in a great variety of forms, the differences being mainly in the arrangement of the heating flues, but all have the central feature, the coking chamber, in common. This is a tubular chamber with vertical sides and cylindrical roof, about 30 ft. long, from 17 to 20 in. wide, and 6 or 7 ft. high, and closed at both ends by sliding doors which are raised by crab winches when the charge is to be drawn. The general arrangements of such an oven are shown in fig. 1, which represents one of the earliest and most popular forms, that of Evence Coppée of Brussels. The coking chambers A B connect by rectangular posts at the springing of the roof, where the gas given off from the top of the charge is fired by air introduced through _c c_. The flames pass downwards through the parallel flues _f f_ along the bottom flue of one oven, and return in the opposite direction under the next to the chimney flue, a further part of the heat being intercepted by placing a range of steam boilers between the ovens and the chimney stack. The charging of the oven is done through the passages D D in the roof from small wagons on transverse lines of rails, the surface being raked level before the doors are closed and luted up. The time of coking is much less than in the beehive ovens and may be from 24 to 36 hours, according to the proportion of volatile matter present. When the gas is completely given off the doors are lifted and the charge is pushed out by the ram--a cast-iron plate of the shape of the cross section of the oven, at the end of a long horizontal bar, which is driven by a rack and pinion movement and pushes the block of coke out of the oven on to the wharf or bank in front where it falls to pieces and is immediately quenched by jets of water from a hose pipe. When sufficiently cooled it is loaded into railway wagons or other conveyances for removal. The ram, together with its motor, and boiler when steam is used, is mounted upon a carriage running upon a line of rails of about 2 ft. gauge along the back of the range of ovens, so that it can be brought up to any one of them in succession.

In some cases, instead of the small coal being charged through the roof of the oven and levelled by hand, it is formed into blocks by being stamped in a slightly moistened condition in a mould consisting of a bottom plate or peel on a racked rod like that of the ram, with movable sides and ends. This, when the ends are removed, is pushed forward into the oven, and the bottom plate is withdrawn by reversing the rack motion. The moulding box is mounted on a carriage like that of the ram, the two being sometimes carried on the same framing. The moulding is done at a fixed station in the centre of the range of ovens by a series of cast-iron stampers driven by an electric motor. This system is useful for coals low in volatile matter, which do not give a coherent coke under ordinary conditions.

Condensing ovens.

In the distilling or by-product ovens the gases, instead of being burned at the point of origin, pass by an uptake pipe in the roof about the centre of the oven into a water-sealed collecting trough or hydraulic main, whence they are drawn by exhausters through a series of air and water cooled condensers and scrubbers. In the first or atmospheric condensers the tar is removed, and in the second ammoniacal water, which is further enriched by a graduated system of scrubbing with weak ammoniacal liquor until it is sufficiently concentrated to be sent to the ammonia stills. The first treatment by scrubbing with creosote or heavy tar oil removes benzene, after which the permanent gaseous residue consisting chiefly of hydrogen and marsh gas is returned to the ovens as fuel.

In the Otto-Hoffmann oven, one of the most generally used forms, vertical side flues like those of Coppée are adopted. The returned gas enters by a horizontal flue along the bottom of the coking chamber, divided into two parts by a mid-feather wall, and is fired by heated air from a Siemens regenerator on the substructure at one end, and the flame rising through one half of the side flues to a parallel collector at the top returns downwards through the flues of the other half and passes out to the chimney through a similar regenerator at the other end. The course of the gases is reversed at intervals of about an hour, as in the ordinary Siemens furnace, each end of the oven having its own gas supply. In the later modification known as the Otto-Hilgenstock, the regenerators are abandoned, but provision is made for more perfect distribution of the heat by a line of sixteen Bunsen burners in each wall; each of these serves two flues, the course of the flame being continuously upwards without reversal. In the newest Otto ovens the same system of burners is combined with regenerators. In the Bauer system, another vertical flue oven, each flue has its own burner, which is of a simplified construction.

In the Carvés oven, the earliest of the by-product ovens, the heating flues are arranged horizontally in parallel series along the entire length of the side walls, the gas being introduced from both ends but at different levels. This system was further developed by H. Simon of Manchester, who added a continuous air "recuperator" heated by the spent flame; this Simon-Carvés system has been extensively adopted in Great Britain. Another horizontal flue oven, the Semet-Solvay, is distinguished by the structure of the flues, which are independent of the dividing walls of the ovens, so that the latter can be made with thinner sides than those of the earlier systems, and are more readily repaired. In the horizontal ovens it is sometimes difficult to maintain the heat when the flues are continuous along the whole length of the wall, especially when the heating value of the gas is reduced by the removal of the heavy hydrocarbons. This difficulty is met by dividing the flues in the middle so as to shorten the length of travel of the flame, and working each end independently. The Hüssener and Koppers systems are two of the best-known examples of this modification.

Coke from retort ovens is not so dense or brilliant as that made in beehive ovens, but the waste being less there is a decided saving, apart from the value of the condensed products. In one instance the coke was found to be about 5% less efficient in the blast furnace, while the yield on the coal charged was increased 10%. In the further treatment of the condensed products by distillation the tar gives burning oil and pitch, the benzene is separated from the creosote oil by steam-heated stills, and the ammoniacal liquor, after some lime has been added to decompose fixed ammonium compounds, is heated to vaporize the ammonia, which is condensed in lead or copper-lined tanks containing strong sulphuric acid to produce a crystalline powder of ammonium sulphate, which accumulates in the receiver and is fished out from time to time. The yield of by-products averages about 1% of ammonium sulphate, about 3½% of tar, and 0.6 to 0.9% of benzene, of the weight of the coal carbonized. After the ovens have been heated and steam supplied for the machinery of the condensing plant and the coke ovens, there is usually a surplus of gas, which may be used for lighting or driving gas-engines. For the latter purpose, however, it is necessary to remove the last traces of tar, which acts very prejudicially in fouling the valves when the gas is not completely purified. The gas given off during the earlier part of the coking process is richer in heavy hydrocarbons and of a higher illuminating value than that of the later period when the temperature is higher. This property is utilized in several large coking plants in America, where the gas from the first ten hours' working is drawn off by a second hydraulic main and sent directly to town gas-works, where it passes through the ordinary purifying treatment, the gas from the second period being alone used for heating the ovens.

Coke is essentially a partially graphitized carbon, its density being about midway between that of coal and graphite, and it should therefore occupy less space than the original coal; but owing to the softening of the charge a spongy structure is set up by the escaping gases, which acts in the other direction, so that for equal bulk coke is somewhat lighter than coal. It is this combination of properties that gives it its chief value in iron smelting, the substance being sufficiently dense to resist oxidation by carbon dioxide in the higher regions of the furnace, while the vesicular structure gives an extended surface for the action of heated air and facilitates rapid consumption at the tuyeres. Compact coke, such as that formed on the inner sides of gas retorts (retort carbon), can only be burned with great difficulty in small furnaces of special construction, but it gives out a great amount of heat.

The most deleterious constituents of coke are ash, sulphur and volatile constituents including water. As the coke yield is only from two-thirds to three-quarters of that of the coal, the original proportion of ash is augmented by one-third or one-half in the product. For this reason it is now customary to crush and wash the coal carefully to remove intermingled patches of shale and dirt before coking, so that the ash may not if possible exceed 10% in the coke. About one-half of the sulphur in the coal is eliminated in coking, so that the percentage in the coke is about the same. It should not be much above 1%. According to the researches of F. Wuest (_Journ. Iron and Steel Inst._, 1906) the sulphur is retained in a complex carbon compound which is not destroyed until the coke is actually consumed.

The older methods of coking and the earlier forms of retort ovens are described in J. Percy, _Metallurgy_, Jordan, _Album du cours de metallurgie_; Phillips and Bauerman, _Handbook of Metallurgy_, and other text-books. A systematic series of articles on the newer forms will be found in _The Engineer_, vol. 82, pp. 205-303 and vol. 83, pp. 207-231; see also Dürre, _Die neuern Koksöfen_ (Leipzig, 1892); D. A.

COL (Fr. for "neck," Lat. _collum_), in physical geography, generally any marked depression upon a high and rugged water-parting over which passage is easy from one valley to another. Such is the Col de Balme between the Trient and Chamounix valleys, where the great inaccessible wall crowned with aiguilles running to the massif of Mt. Blanc is broken by a gentle downward curve with smooth upland slopes, over which a footpath gives easy passage. The col is usually formed by the head-waters of a stream eating backward and lowering the water-parting at the head of its valley. In early military operations, the march of an army was always over a col, which has at all times considerable commercial importance in relation to roads in high mountain regions.

COLBERT, JEAN BAPTISTE (1619-1683), French statesman, was born at Reims, where his father and grandfather were merchants. He claimed to be the descendant of a noble Scottish family, but the evidence for this is lacking. His youth is said to have been spent in a Jesuit college, in the office of a Parisian banker, and in that of a Parisian notary, Chapelain, the father of the poet. But the first fact on which we can rely with confidence is that, when not yet twenty, he obtained a post in the war-office, by means of the influence that he possessed through the marriage of one of his uncles to the sister of Michel Le Tellier, the secretary of state for war. During some years he was employed in the inspection of troops and other work of the kind, but at length his ability, his extraordinary energy and his untiring laboriousness induced Le Tellier to make him his private secretary. These qualities, combined, it must be confessed, with a readiness to seize every opportunity of advancement, soon brought Colbert both wealth and influence. In 1647 we find him receiving the confiscated goods of his uncle Pussort, in 1648 obtaining 40,000 crowns with his wife Marie Charron, in 1649 appointed councillor of state.

It was the period of the wars of the Fronde; and in 1651 the triumph of the Condé family drove Cardinal Mazarin from Paris. Colbert, now aged thirty-two, was engaged to keep him acquainted with what should happen in the capital during his absence. At first Colbert's position was far from satisfactory; for the close wary Italian treated him merely as an ordinary agent. On one occasion, for example, he offered him 1000 crowns. The gift was refused somewhat indignantly; and by giving proof of the immense value of his services, Colbert gained all that he desired. His demands were not small; for, with an ambition mingled, as his letters show, with strong family affection, he aimed at placing all his relatives in positions of affluence and dignity; and many a rich benefice and important public office was appropriated by him to that purpose. For these favours, conferred upon him by his patron with no stinted hand, his thanks were expressed in a most remarkable manner; he published a letter defending the cardinal from the charge of ingratitude which was often brought against him, by enumerating the benefits that he and his family had received from him (April 1655). Colbert obtained, besides, the higher object of his ambition; the confidence of Mazarin, so far as it was granted to any one, became his, and he was entrusted with matters of the gravest importance. In 1659 he was giving directions as to the suppression of the revolt of the gentry which threatened in Normandy, Anjou and Poitou, with characteristic decision arresting those whom he suspected, and arranging every detail of their trial, the immediate and arbitrary destruction of their castles and woods, and the execution of their chief, Bonnesson. In the same year we have evidence that he was already planning his great attempt at financial reform. His earliest tentative was the drawing up of a _mémoire_ to Mazarin, showing that of the taxes paid by the people not one-half reached the king. The paper also contained an attack upon the superintendent Nicholas Fouquet (q.v.), and being opened by the postmaster of Paris, who happened to be a spy of Fouquet's, it gave rise to a bitter quarrel, which, however, Mazarin repressed during his lifetime.

In 1661 the death of Mazarin allowed Colbert to take the first place in the administration, and he made sure of the king's favour by revealing to him some of Mazarin's hidden wealth. It was some time before he assumed official dignities; but in January 1664 he obtained the post of superintendent of buildings; in 1665 he was made controller-general; in 1669 he became minister of the marine; and he was also appointed minister of commerce, the colonies and the king's palace. In short, he soon acquired power in every department except that of war.

A great financial and fiscal reform at once claimed all his energies. Not only the nobility, but many others who had no legal claim to exemption, paid no taxes; the weight of the burden fell on the wretched country-folk. Colbert sternly and fearlessly set about his task. Supported by the young king, Louis XIV., he aimed the first blow at the greatest of the extortioners--the bold and powerful superintendent, Fouquet; whose fall, in addition, secured his own advancement.

The office of superintendent and many others dependent upon it being abolished the supreme control of the finances was vested in a royal council. The sovereign was its president; but Colbert, though for four years he only possessed the title of intendant, was its ruling spirit, great personal authority being conferred upon him by the king. The career on which Colbert now entered must not be judged without constant remembrance of the utter rottenness of the previous financial administration. His ruthlessness in this case, dangerous precedent as it was, was perhaps necessary; individual interests could not be respected. Guilty officials having been severely punished, the fraudulent creditors of the government remained to be dealt with. Colbert's method was simple. Some of the public loans were totally repudiated, and from others a percentage was cut off, which varied, at first according to his own decision, and afterwards according to that of the council which he established to examine all claims against the state.

Much more serious difficulties met his attempts to introduce equality in the pressure of the taxes on the various classes. To diminish the number of the privileged was impossible, but false claims to exemption were firmly resisted, and the unjust direct taxation was lightened by an increase of the indirect taxes, from which the privileged could not escape. The mode of collection was at the same time immensely improved.

Order and economy being thus introduced into the working of the government, the country, according to Colbert's vast yet detailed plan, was to be enriched by commerce. Manufactures were fostered in every way he could devise. New industries were established, inventors protected, workmen invited from foreign countries, French workmen absolutely prohibited to emigrate. To maintain the character of French goods in foreign markets, as well as to afford a guarantee to the home consumer, the quality and measure of each article were fixed by law, breach of the regulations being punished by public exposure of the delinquent and destruction of the goods, and, on the third offence, by the pillory. But whatever advantage resulted from this rule was more than compensated by the disadvantages it entailed. The production of qualities which would have suited many purposes of consumption was prohibited, and the odious supervision which became necessary involved great waste of time and a stereotyped regularity which resisted all improvements. And other parts of Colbert's schemes deserve still less equivocal condemnation. By his firm maintenance of the corporation system, each industry remained in the hands of certain privileged bourgeois; in this way, too, improvement was greatly discouraged; while to the lower classes opportunities of advancement were closed. With regard to international commerce Colbert was equally unfortunate in not being in advance of his age; the tariffs he published were protective to an extreme. The interests of internal commerce were, however, wisely consulted. Unable to abolish the duties on the passage of goods from province to province, he did what he could to induce the provinces to equalize them. The roads and canals were improved. The great canal of Languedoc was planned and constructed by Pierre Paul Riquet (1604-1680) under his patronage. To encourage trade with the Levant, Senegal, Guinea and other places, privileges were granted to companies; but, like the more important East India Company, all were unsuccessful. The chief cause of this failure, as well as of the failure of the colonies, on which he bestowed so much watchful care, was the narrowness and rigidity of the government regulations.

The greatest and most lasting of Colbert's achievements was the establishment of the French marine. The royal navy owed all to him, for the king thought only of military exploits. For its use, Colbert reconstructed the works and arsenal of Toulon, founded the port and arsenal of Rochefort, and the naval schools of Rochefort, Dieppe and Saint-Malo, and fortified, with some assistance from Vauban (who, however, belonged to the party of his rival Louvois), among other ports those of Calais, Dunkirk, Brest and Havre. To supply it with recruits he invented his famous system of classes, by which each seaman, according to the class in which he was placed, gave six months' service every three or four or five years. For three months after his term of service he was to receive half-pay; pensions were promised; and, in short, everything was done to make the navy popular. There was one department, however, that was supplied with men on a very different principle. Letters exist written by Colbert to the judges requiring them to sentence to the oar as many criminals as possible, including all those who had been condemned to death; and the convict once chained to the bench, the expiration of his sentence was seldom allowed to bring him release. Mendicants also, against whom no crime had been proved, contraband dealers, those who had been engaged in insurrections, and others immeasurably superior to the criminal class, nay, innocent men--Turkish, Russian and negro slaves, and poor Iroquois Indians, whom the Canadians were ordered to entrap--were pressed into that terrible service. By these means the benches of the galleys were filled, and Colbert took no thought of the long unrelieved agony borne by those who filled them.

Nor was the mercantile marine forgotten. Encouragement was given to the building of ships in France by allowing a premium on those built at home, and imposing a duty on those brought from abroad; and as French workmen were forbidden to emigrate, so French seamen were forbidden to serve foreigners on pain of death.

Even ecclesiastical affairs, though with these he had no official concern, did not altogether escape Colbert's attention. He took a subordinate part in the struggle between the king and Rome as to the royal rights over vacant bishoprics; and he seems to have sympathized with the proposal that was made to seize part of the wealth of the clergy. In his hatred of idleness, he ventured to suppress no less than seventeen fêtes, and he had a project for lessening the number of those devoted to clerical and monastic life, by fixing the age for taking the vows some years later than was then customary. With heresy he was at first unwilling to interfere, for he was aware of the commercial value of the Huguenots; but when the king resolved to make all France Roman Catholic, he followed him and urged his subordinates to do all that they could to promote conversions.

In art and literature Colbert took much interest. He possessed a remarkably fine private library, which he delighted to fill with valuable manuscripts from every part of Europe where France had placed a consul. He has the honour of having founded the Academy of Sciences (now called the Institut de France), the Observatory, which he employed Claude Perrault to build and brought G. D. Cassini (1625-1712) from Italy to superintend, the Academies of Inscriptions and Medals, of Architecture and of Music, the French Academy at Rome, and Academies at Arles, Soissons, Nîmes and many other towns, and he reorganized the Academy of Painting and Sculpture which Richelieu had established. He was a member of the French Academy; and one very characteristic rule, recorded to have been proposed by him with the intention of expediting the great Dictionary, in which he was much interested, was that no one should be accounted present at any meeting unless he arrived before the hour of commencement and remained till the hour for leaving. In 1673 he presided over the first exhibition of the works of living painters; and he enriched the Louvre with hundreds of pictures and statues. He gave many pensions to men of letters, among whom we find Molière, Corneille, Racine, Boileau, P. D. Huet (1630-1721) and Antoine Varillas (1626-1696), and even foreigners, as Huyghens, Vossius the geographer, Carlo Dati the Dellacruscan, and Heinsius the great Dutch scholar. There is evidence to show that by this munificence he hoped to draw out praises of his sovereign and himself; but this motive certainly is far from accounting for all the splendid, if in some cases specious, services that he rendered to literature, science and art.

Indeed to everything that concerned the interests of France Colbert devoted unsparing thought and toil. Besides all that has been mentioned, he found time to do something for the better administration of justice (the codification of ordinances, the diminishing of the number of judges, the reduction of the expense and length of trials for the establishment of a superior system of police) and even for the improvement of the breed of horses and the increase of cattle. As superintendent of public buildings he enriched Paris with boulevards, quays and triumphal arches; he relaid the foundation-stone of the Louvre, and brought Bernin from Rome to be its architect; and he erected its splendid colonnade upon the plan of Claude Perrault, by whom Bernin had been replaced. He was not permitted, however, to complete the work, being compelled to yield to the king's preference for residences outside Paris, and to devote himself to Marly and Versailles.

Amid all these public labours his private fortune was never neglected. While he was reforming the finances of the nation, and organizing its navy, he always found time to direct the management of his smallest farm. He died extremely rich, and left fine estates all over France. He had been created marquis de Seignelay, and for his eldest son he obtained the reversion of the office of minister of marine; his second son became archbishop of Rouen; and a third son, the marquis d'Ormoy, became superintendent of buildings.

To carry out his reforms, Colbert needed peace; but the war department was in the hands of his great rival Louvois, whose influence gradually supplanted that of Colbert with the king. Louis decided on a policy of conquest. He was deaf also to all the appeals against the other forms of his boundless extravagance which Colbert, with all his deference towards his sovereign, bravely ventured to make.[1] Thus it came about that, only a few years after he had commenced to free the country from the weight of the loans and taxes which crushed her to the dust, Colbert was forced to heap upon her a new load of loans and taxes more heavy than the last. Henceforth his life was a hopeless struggle, and the financial and fiscal reform which, with the great exception of the establishment of the navy, was the most valuable service to France contemplated by him, came to nought.

Depressed by his failure, deeply wounded by the king's favour for Louvois, and worn out by overwork, Colbert's strength gave way at a comparatively early age. In 1680 he was the constant victim of severe fevers, from which he recovered for a time through the use of quinine prescribed by an English physician. But in 1683, at the age of sixty-four, he was seized with a fatal illness, and on the 6th of September he expired. It was said that he died of a broken heart, and a conversation with the king is reported in which Louis disparagingly compared the buildings of Versailles, which Colbert was superintending, with the works constructed by Louvois in Flanders. He took to bed, it is true, immediately afterwards, refusing to receive all messages from the king; but his constitution was utterly broken before, and a post-mortem examination proved that he had been suffering from stone. His body was interred in the secrecy of night, for fear of outrage from the Parisians, by whom his name was cordially detested.

Colbert was a great statesman, who did much for France. Yet his insight into political science was not deeper than that of his age; nor did he possess any superiority in moral qualities. His rule was a very bad example of over-government. He did not believe in popular liberty;, the parlements and the states-general received no support from him. The technicalities of justice he never allowed to interfere with his plans; but he did not hesitate to shield his friends. He trafficked in public offices for the profit of Mazarin and in his own behalf. He caused the suffering of thousands in the galleys; he had no ear, it is said, for the cry of the suppliant. There was indeed a more human side to his character, as is shown in his letters, full of wise advice and affectionate care, to his children, his brothers, his cousins even. Yet to all outside he was "the man of marble." Madame de Sévigné called him "the North." To diplomacy he never pretended; persuasion and deceit were not the weapons he employed; all his work was carried out by the iron hand of authority. He was a great statesman in that he conceived a magnificent yet practicable scheme for making France first among nations, and in that he possessed a matchless faculty for work, neither shrinking from the vastest undertakings nor scorning the most trivial details.

Numerous _vies_ and _éloges_ of Colbert have been published; but the most thorough student of his life and administration was Pierre Clément, member of the Institute, who in 1846 published his _Vie de Colbert_, and in 1861 the first of the 9 vols. of the _Lettres, instructions, et mémoires de Colbert_. The historical introductions prefixed to each of these volumes have been published by Mme. Clément under the title of the _Histoire de Colbert et de son administration_ (3rd ed., 1892). The best short account of Colbert as a statesman is that in Lavisse, _Histoire de France_ (1905), which gives a thorough study of the administration. Among Colbert's papers are _Mémoires sur les affaires de finance de France_ (written about 1663), a fragment entitled _Particularités secrètes de la vie du Roy_, and other accounts of the earlier part of the reign of Louis XIV. (J. T. S.)

COLBERT DE CROISSY, CHARLES, MARQUIS (1625-1696), French diplomatist, like his elder brother Jean Baptiste Colbert, began his career in the office of the minister of war Le Tellier. In 1656 he bought a counsellorship at the parlement of Metz, and in 1658 was appointed intendant of Alsace and president of the newly-created sovereign council of Alsace. In this position he had to re-organize the territory recently annexed to France. The steady support of his brother at court gained for him several diplomatic missions--to Germany and Italy (1659-1661). In 1662 he became marquis de Croissy and _président à mortier_ of the parlement of Metz. After various intendancies, at Soissons (1665), at Amiens (1666), and at Paris (1667), he turned definitely to diplomacy. In 1668 he represented France at the conference of Aix-la-Chapelle; and in August of the same year was sent as ambassador to London, where he was to negotiate the definite treaty of alliance with Charles II. He arranged the interview at Dover between Charles and his sister Henrietta of Orleans, gained the king's personal favour by finding a mistress for him, Louise de Kéroualle, maid of honour to Madame, and persuaded him to declare war against Holland. The negotiation of the treaty of Nijmwegen (1676-1678) still further increased his reputation as a diplomatist and Louis XIV. made him secretary of state for foreign affairs after the disgrace of Arnauld de Pomponne, brought about by his brother, 1679. He at once assumed the entire direction of French diplomacy. Foreign ambassadors were no longer received and diplomatic instructions were no longer given by other secretaries of state. It was he, not Louvois, who formed the idea of annexation during a time of peace, by means of the chambers of reunion. He had outlined this plan as early as 1658 with regard to Alsace. His policy at first was to retain the territory annexed by the chambers of reunion without declaring war, and for this purpose he signed treaties of alliance with the elector of Brandenburg (1681), and with Denmark (1683); but the troubles following upon the revocation of the edict of Nantes (1685) forced him to give up his scheme and to prepare for war with Germany (1688). The negotiations for peace had been begun again when he died, on the 28th of July 1696. His clerk, Bergeret, was his invaluable assistant.

COLBURN, HENRY (d. 1855), British publisher, obtained his earliest experience of bookselling in London at the establishment of W. Earle, Albemarle Street, and afterwards as an assistant at Morgan's Library, Conduit Street, of which in 1816 he became proprietor. He afterwards removed to New Burlington Street, where he established himself as a publisher, resigning the Conduit Street Library to Messrs Saunders & Otley. In 1814 he originated the _New Monthly Magazine_, of which at various times Thomas Campbell, Bulwer Lytton, Theodore Hook and Harrison Ainsworth were editors. Colburn published in 1818 _Evelyn's Diary_, and in 1825 the _Diary of Pepys_, edited by Lord Braybrooke, paying £2200 for the copyright. He also issued Disraeli's first novel, _Vivian Grey_, and a large number of other works by Theodore Hook, G. P. R. James, Marryat and Bulwer Lytton. In 1829 Richard Bentley (q.v.) was taken into partnership; and in 1832 Colburn retired, but set up again soon afterwards independently in Great Marlborough Street; his business was taken over in 1841 by Messrs Hurst & Blackett. Henry Colburn died on the 16th of August 1855, leaving property to the value of £35,000.

COLBURN, ZERAH (1804-1840), American mathematical prodigy, was born at Cabot, Vermont, on the 1st of September 1804. At a very early age he developed remarkable powers of calculating with extreme rapidity, and in 1810 his father began to exhibit him. As a performing prodigy he visited Great Britain and France. From 1816 to 1819 he studied in Westminster school, London. After the death of his father in 1824 he returned to America, and from 1825 to 1834 he was a Methodist preacher. As he grew older his extraordinary calculating powers diminished. From 1835 until his death, on the 2nd of March 1840, he was professor of languages at the Norwich University in Vermont. He published a _Memoir_ of his life in 1833.

His nephew, also named ZERAH COLBURN (1832-1870), was a well-known mechanical engineer; the editor successively of the _Railroad Advocate_, in New York, _The Engineer_, in London, and _Engineering_, in London; and the author of a work entitled _The Locomotive Engine_ (1851).

COLBY, THOMAS FREDERICK (1784-1852), British major-general and director of ordnance survey, was born at St Margaret's, Rochester, on the 1st of September 1784, a member of a South Wales family. Entering the Royal Engineers he began in 1802 a life-long connexion with the Ordnance Survey department. His most important work was the survey of Ireland. This he planned in 1824, and was engaged upon it until 1846. The last sheets of this survey were almost ready for issue in that year when he reached the rank of major-general, and according to the rules of the service had to vacate his survey appointment. He was the inventor of the compensation bar, an apparatus used in base-measurements. He died at New Brighton on the 9th of October 1852.

COLCHAGUA, a province of central Chile, bounded N. by Santiago and O'Higgins, E. by Argentina, S. by Curicó, and W. by the Pacific. Its area is officially estimated at 3856 sq. m.; pop. (1895) 157,566. Extending across the great central valley of Chile, the province has a considerable area devoted to agriculture, but much attention is given to cattle and mining. Its principal river is the Rapel, sometimes considered as the southern limit of the Inca empire. Its greatest tributary is the Cachapoal, in the valley of which, among the Andean foothills, are the popular thermal mineral baths of Cauquenes, 2306 ft. above sea-level. The state central railway from Santiago to Puerto Montt crosses the province and has two branches within its borders, one from Rengo to Peumo, and one from San Fernando via Palmilla to Pichilemu on the coast. The principal towns are the capital, San Fernando, Rengo and Palmilla. San Fernando is one of the several towns founded in 1742 by the governor-general José de Manso, and had a population of 7447 in 1895. Rengo is an active commercial town and had a population of 6463 in 1895.

COLCHESTER, CHARLES ABBOT, 1ST BARON (1757-1829), born at Abingdon, was the son of Dr John Abbot, rector of All Saints, Colchester, and, by his mother's second marriage, half-brother of the famous Jeremy Bentham. From Westminster school Charles Abbot passed to Christ Church, Oxford, at which he gained the chancellor's medal for Latin verse as well as the Vinerian scholarship. In 1795, after having practised twelve years as a barrister, and published a treatise proposing the incorporation of the judicial system of Wales with that of England, he was appointed to the office previously held by his brother of clerk of the rules in the king's bench; and in June of the same year he was elected member of parliament for Helston, through the influence of the duke of Leeds. In 1796 Abbot commenced his career as a reformer in parliament by obtaining the appointment of two committees--the one to report on the arrangements which then existed as to temporary laws or laws about to expire, the other to devise methods for the better publication of new statutes. To the latter committee, and a second committee which he proposed some years later, it is owing that copies of new statutes were thenceforth sent to all magistrates and municipal bodies. To Abbot's efforts were also due the establishment of the Royal Record Commission, the reform of the system which had allowed the public money to lie for some time at long interest in the hands of the public accountants, by charging them with payment of interest, and, most important of all, the act for taking the first census, that of 1801. On the formation of the Addington ministry in March 1801 Abbot became chief secretary and privy seal for Ireland; and in the February of the following year he was chosen speaker of the House of Commons--a position which he held with universal satisfaction till 1817, when an attack of erysipelas compelled him to retire. In response to an address of the Commons, he was raised to the peerage as Baron Colchester, with a pension of £4000, of which £3000 was to be continued to his heir. He died on the 8th of May 1829. His speeches against the Roman Catholic claims were published in 1828.

He was succeeded by his eldest son CHARLES (d. 1867), postmaster-general in 1858; and the latter by his son REGINALD CHARLES EDWARD (b. 1842), as 3rd baron.

COLCHESTER a market town, river port and municipal and parliamentary borough of Essex, England; 52 m. N. E. by E. from London by the Great Eastern railway. Pop. (1901) 38,373. It lies on the river Colne, 12 m. from the open sea. Among numerous buildings of antiquarian interest the first is the ruined keep of the castle, a majestic specimen of Norman architecture, the largest of its kind in England, covering nearly twice the area of the White Tower in London. It was erected in the reign of William I. or William II., and is quadrangular, turreted at the angles. As in other ancient buildings in Colchester there are evidences of the use of material from the Roman town which occupied the site, but it is clearly of Norman construction. Here is the museum of the Essex Archaeological Society, with a remarkable collection of Roman antiquities, and a library belonging to the Round family, who own the castle. Among ecclesiastical buildings are remains of two monastic foundations--the priory of St Botolph, founded early in the 12th century for Augustinian canons, of which part of the fine Norman west front (in which Roman bricks occur), and of the nave arcades remain; and the restored gateway of the Benedictine monastery of St John, founded by Eudo, steward to William II. This is a beautiful specimen of Perpendicular work, embattled, flanked by spired turrets, and covered with panel work. The churches of Holy Trinity, St Martin and St Leonard at Hythe are of antiquarian interest; the first has an apparently pre-Norman tower and the last preserves some curious frescoes.

The principal modern buildings are the town hall, corn exchange, free library, the Eastern Counties' asylum, Essex county hospital and barracks. The town has long been an important military centre with a large permanent camp. There are a free grammar school (founded 1539), a technical and university extension college, a literary institute and medical and other societies. Castle Park is a public ground surrounding the castle. Colchester is the centre of an agricultural district, and has extensive corn and cattle markets. Industries include founding, engineering, malting, flour-milling, rose-growing and the making of clothing and boots and shoes. The oyster fisheries at the mouth of the Colne, for which the town has been famous for centuries, belong to the corporation, and are held on a ninety-nine years' lease by the Colne Fishery Company, incorporated under an act of 1870. The harbour, with quayage at the suburb of Hythe, is controlled by the corporation. The parliamentary borough, which is co-extensive with the municipal, returns one member. The municipal corporation consists of a mayor, 8 aldermen and 24 councillors. Area 11,333 acres.

The Roman town, _Colonia Victricensis Camalodunum_ (or _Camulodunum_), was of great importance. It was founded by Claudius, early in the period of the Roman conquest, as a municipality with discharged Roman soldiers as citizens, to assist the Roman dominion and spread its civilization. Under Queen Boadicea the natives burned the town and massacred the colonists; but Camalodunum soon rose to fresh prosperity and flourished throughout the Roman period. Its walls and some other remains, including the guardroom at the principal gate, can still be clearly traced, and many such relics as sculptures, inscriptions, pavements and pottery have been discovered. When the borough originated is not known, but Domesday Book mentions two hundred and seventy-six burgesses and land _in commune burgensium_, a phrase that may point to a nascent municipal corporation. The first charter given by Richard I. in 1189 granted the burghers leave to choose their bailiffs and a justice to hold the pleas of the crown within the borough, freedom from the obligation of duel, freedom of passage and pontage through England, free warren, fishery and custom as in the time of Henry I., and other privileges. An _inspeximus_ of this charter by Henry III. in 1252 granted the burgesses the return of certain writs. The charters were confirmed by various kings, and new grants obtained in 1447 and 1535. In 1635 Charles I. granted a fresh charter, which replaced the bailiffs by a mayor, and in 1653 Cromwell altered it to secure a permanent majority for his party on the corporation. But his action was undone in 1659, and in 1663 Charles II. granted a new charter. In 1684 the charters were surrendered, and a new one obtained reserving to the crown power to remove the mayor and alderman, and this one was further modified by James II. But the charter of 1663 was confirmed in 1693 and remained in force till 1741, when the liberties were allowed to lapse. In 1763 George III. made the borough a renewed grant of its liberties. Colchester returned two members to parliament from 1295 until 1885. Fairs were granted by Richard I. in 1189 to the hospital of St Mary Magdalene, and by Edward II. in 1319 to the town for the eve of and feast of St Denis and the six following days--a fair which is still held. In the 13th century Colchester was sufficiently important as a port to pay a fee-farm of £46, its ships plying to Winchelsea and France. Elizabeth and James I. encouraged Flemish settlers in the manufacture of baize ("bays and says"), which attained great importance, so that a charter of Charles I. speaks of burgesses industriously exercising the manufacture of cloth. Both Camden and Fuller mention the trade in barrelled oysters and candied eringo-root. The most notable event in the history of the town was its siege by Fairfax in 1648, when the raw levies of the Royalists in the second civil war held his army at bay for nearly eleven weeks, only surrendering when starved out, and when Cromwell's victory in the north made further resistance useless. Colchester was made the see of a suffragan bishop by King Henry VIII., and two bishops were in succession appointed by him; no further appointments, however, were made until the see was re-established under Queen Victoria.

COLCHESTER, a township of Chittenden county, Vermont, U.S.A., on Lake Champlain, immediately N.E. of Burlington, from which it is separated by the Winooski river. Pop. (1900) 5352; (1910) 6450. It is served by the Central Vermont railway. The surface is generally gently rolling, and in places along the banks of the Winooski or Onion river, the shore of the lake, and in the valleys, it is very picturesque. At Mallett's Bay, an arm of Lake Champlain, 2 m. long and 1½ m. wide, several large private schools hold summer sessions. The soil is varied, much of it being good meadow land or well adapted to the growing of grain and fruit. The township has two villages: Colchester Centre, a small, quiet settlement, and Winooski (pop. in 1900, 3783) on the Winooski river. This stream furnishes good water power, and the village has manufactories of cotton and woollen goods, lumber, woodenware, gold and silver plated ware, carriages, wagons and screens. Within the township there is a United States military reservation, Fort Ethan Allen. The village was founded in 1772 by Ira Allen and for many years it was known as "Allen's Settlement"; but later it was called Winooski Falls, and in 1866 it was incorporated as the Village of Winooski.

COLCHICUM, the Meadow Saffron, or Autumn Crocus (_Colchicum autumnale_), a perennial plant of the natural order, Liliaceae, found wild in rich moist meadow-land in England and Ireland, in middle and southern Europe, and in the Swiss Alps. It has pale-purple flowers, rarely more than three in number; the perianth is funnel-shaped, and produced below into a long slender tube, in the upper part of which the six stamens are inserted. The ovary is three-celled, and lies at the bottom of this tube. The leaves are three or four in number, flat, lanceolate, erect and sheathing; and there is no stem. Propagation is by the formation of new corms from the parent corm, and by seeds. The latter are numerous, round, reddish-brown, and of the size of black mustard-seeds. The corm of the meadow-saffron attains its full size in June or early in July. A smaller corm is then formed from the old one, close to its root; and this in September and October produces the crocus-like flowers. In the succeeding January or February it sends up its leaves, together with the ovary, which perfects its seeds during the summer. The young corm, at first about the diameter of the flower-stalk, grows continuously, till in the following July it attains the size of a small apricot. The parent corm remains attached to the new one, and keeps its form and size till April in the third year of its existence, after which it decays. In some cases a single corm produces several new plants during its second spring by giving rise to immature corms.

_C. autumnale_ and its numerous varieties as well as other species of the genus, are well known in cultivation, forming some of the most beautiful of autumn-flowering plants. They are very easy to cultivate and do not require lifting. The most suitable soil is a light, sandy loam enriched with well decomposed manure, in a rather moist situation. The corms should be planted not less than 3 in. deep. Propagation is effected by seed or increase of corms; the seed should be sown as soon as it is ripe in June or July.

Colchicum was known to the Greeks under the name of [Greek: Kolchikon], from [Greek: Kolchis], or Colchis, a country in which the plant grew; and it is described by Dioscorides as a poison. In the 17th century the corms were worn by some of the German peasantry as a charm against the plague. The drug was little used till 1763, when Baron Störck of Vienna introduced it for the treatment of dropsy. Its use in febrile diseases, at one time extensive, is now obsolete. As a specific for gout colchicum was early employed by the Arabs; and the preparation known as _eau médicinale_, much resorted to in the 18th century for the cure of gout, owes its therapeutic virtues to colchicum; but general attention was first directed by Sir Everard Home to the use of the drug in gout.

For medical purposes the corm should be collected in the early summer and, after the outer coat has been removed, should be sliced and dried at a temperature of 130° to 150° F.

The chief constituents of colchicum are two alkaloids, _colchicine_ and _veratrine_. Colchicine is the active principle and may be given in full form in doses of 1/32 to 1/16 grain. It is a yellow, micro-crystalline powder, soluble in water, alcohol and chloroform, and forming readily decomposed salts with acids. It is the methyl ester of a neutral body _colchicein_, which may be obtained in white acicular crystals.

The official dose of powdered colchicum is 2 to 5 grains, which may be given in a cachet. The British Pharmacopoeia contains (1) an extract of the fresh corm, having doses of ¼ to 1 grain, and (2) the _Vinum Colchici_, made by treating the dried corm with sherry and given in doses of 10 to 30 minims. This latter is the preparation still most generally used, though the presence of veratrine both in the corm and the seeds renders the use of colchicine itself theoretically preferable. The dried ripe seeds of this plant are also used in medicine. They are exceedingly hard and difficult to pulverize, odourless, bitter and readily confused with black mustard seeds. They contain a volatile oil which does not occur in the corm, and their proportion of colchicine is higher, for which reason the _Tinctura Colchici Seminum_--dose 5 to 15 minims--is preferable to the wine prepared from the corm. At present this otherwise excellent preparation is not standardized, but the suggestion has been made that it should be standardized to contain 0.1% of colchicine. The salicylate of colchicine is stable in water and may be given in doses of about one-thirtieth of a grain. It is often known as Colchi-Sal.

_Pharmacology._--Colchicum or colchicine, when applied to the skin, acts as a powerful irritant, causing local pain and congestion. When inhaled, the powder causes violent sneezing, similar to that produced by veratrine itself, which is, as already stated, a constituent of the corm. Taken internally, colchicum or colchicine markedly increases the amount of bile poured into the alimentary canal, being amongst the most powerful of known cholagogues. Though this action doubtless contributes to its remarkable therapeutic power, it is very far from being an adequate explanation of the virtues of the drug in gout. In larger doses colchicum or colchicine acts as a most violent gastrointestinal irritant, causing terrible pain, colic, vomiting, diarrhoea, haemorrhage from the bowel, thirst and ultimately death from collapse. This is accelerated by a marked depressant action upon the heart, similar to that produced by veratrine and aconite. Large doses also depress the nervous system, weakening the anterior horns of grey matter in the spinal cord so as ultimately to cause complete paralysis, and also causing a partial insensibility of the cutaneous nerves of touch and pain. The action of colchicum or colchicine upon the kidneys has been minutely studied, and it is asserted on the one hand that the urinary solids are much diminished and, on the other hand, that they are markedly increased, the specific gravity of the secretion being much raised. These assertions, and the total inadequacy of the pharmacology of colchicum, as above detailed, to explain its specific therapeutic property, show that the secret of colchicum is as yet undiscovered.

The sole but extremely important use of this drug is as a specific for gout. It has an extraordinary power over the pain of acute gout; it lessens the severity and frequency of the attacks when given continuously between them, and it markedly controls such symptoms of gout as eczema, bronchitis and neuritis, whilst it is entirely inoperative against these conditions when they are not of gouty origin. Despite the general recognition of these facts, the pharmacology of colchicum has hitherto thrown no light on the pathology of gout, and the pathology of gout has thrown no light upon the manner in which colchicum exerts its unique influence upon this disease. Veratrine is useless in the treatment of gout. A further curious fact, doubtless of very great significance, but hitherto lacking interpretation, is that the administration of colchicum during an acute attack of gout may often hasten the oncoming of the next attack; and this property, familiar to many gouty patients, may not be affected by the administration of small doses after the attack. Altogether colchicum is a puzzle, and will remain so until the efficient poison of gout is isolated and defined. When that is done, colchicine may be found to exhibit a definite chemical interaction with this hitherto undiscovered substance.

In _colchicum poisoning_, empty the stomach, give white of egg, olive or salad oil, and water. Use hot bottles and stimulants, especially trying to counteract the cardiac depression by atropine, caffeine, strophanthin, &c.

COLCHIS, in ancient geography, a nearly triangular district of Asia Minor, at the eastern extremity of the Black Sea, bounded on the N. by the Caucasus, which separated it from Asiatic Sarmatia, E. by Iberia, S. by the Montes Moschici, Armenia and part of Pontus, and W. by the Euxine. The ancient district is represented roughly by the modern province of Kutais (formerly Mingrelia). The name of Colchis first appears in Aeschylus and Pindar. It was inhabited by a number of tribes whose settlements lay chiefly along the shore of the Black Sea. The chief of those were the Lazi, Moschi, Apsilae, Abasci, Sagadae, Suani and Coraxi. These tribes differed so completely in language and appearance from the surrounding nations, that the ancients originated various theories to account for the phenomenon. Herodotus, who states that they, with the Egyptians and the Ethiopians, were the first to practise circumcision, believed them to have sprung from the relics of the army of Sesostris (q.v.), and thus regarded them as Egyptians. Apollonius Rhodius (_Argon_, iv. 279) states that the Egyptians of Colchis preserved as heirlooms a number of wooden [Greek: kurbeis] (tablets) showing seas and highways with considerable accuracy. Though this theory was not generally adopted by the ancients, it has been defended, but not with complete success, by some modern writers. It is quite possible that there was an ancient trade connexion between the Colchians and the Mediterranean peoples. We learn that women were buried, while the corpses of men were suspended on trees. The principal coast town was the Milesian colony of Dioscurias (Roman Sebastopolis; mod. Sukhum Kaleh), the ancient name being preserved in the modern C. Iskuria. The chief river was the Phasis (mod. Rion). From Colchis is derived the name of the plant Colchicum (q.v.).

Colchis was celebrated in Greek mythology as the destination of the Argonauts, the home of Medea and the special domain of sorcery. Several Greek colonies were founded there by Miletus. At a remote period it seems to have been incorporated with the Persian empire, though the inhabitants evidently enjoyed a considerable degree of independence; in this condition it was found by Alexander the Great, when he invaded Persia. From this time till the era of the Mithradatic wars nothing is known of its history. At the time of the Roman invasion it seems to have paid a nominal homage to Mithradates the Great and to have been ruled over by Machares, his second son. On the defeat of Mithradates by Pompey, it became a Roman province. After the death of Pompey, Pharnaces, the son of Mithradates, rose in rebellion against the Roman yoke, subdued Colchis and Armenia, and made head, though but for a short time, against the Roman arms. After this Colchis was incorporated with Pontus, and the Colchians are not again alluded to in ancient history till the 6th century, when, along with the Abasci or Abasgi, under their king Gobazes, whose mother was a Roman, they called in the aid of Chosroes I. of Persia (541). The importance of the district, then generally called Lazica from the Lazi (cf. mod. Lazistan) who led the revolt, was due to the fact that it was the only remaining bar which held the Persians, already masters of Iberia, from the Black Sea. It had therefore been specially garrisoned by Justinian under first Peter, a Persian slave, and subsequently Johannes Tzibos, who built Petra on the coast as the Roman Headquarters. Tzibos took advantage of the extreme poverty of the Lazi to create a Roman monopoly by which he became a middleman for all the trade both export and import. Chosroes at once accepted the invitation of Gobazes and succeeded in capturing Petra (A.D. 541). The missionary zeal of the Zoroastrian priests soon caused discontent among the Christian inhabitants of Colchis, and Gobazes, perceiving that Chosroes intended to Persianize the district, appealed to Rome, with the result that in 549 one Dagisthaeus was sent out with 7000 Romans and 1000 auxiliaries of the Tzani (Zani, Sanni). The "Lazic War" lasted till 556 with varying success. Petra was recaptured in 551 and Archaeopolis was held by the Romans against the Persian general Mermeroes. Gobazes was assassinated in 552, but the Persian general Nachoragan was heavily defeated at Phasis in 553.

By the peace of 562 the district was left in Roman possession, but during the next 150 years it is improbable that the Romans exercised much authority over it. In 697 we hear of a revolt against Rome led by Sergius the Patrician, who allied himself with the Arabs. Justinian II. in his second period of rule sent Leo the Isaurian, afterwards emperor, to induce the Alans to attack the Abasgi. The Alans, having gained knowledge of the district by a trick, invaded Lazica, and, probably in 712, a Roman and Armenian army laid siege to Archaeopolis. On the approach of a Saracen force they retired, but a small plundering detachment was cut off. Ultimately Leo joined this band and aided by the Apsilian chief Marinus escaped with them to the coast.

From the beginning of the 14th to the end of the 17th century the district under the name Mingrelia (q.v.) was governed by an independent dynasty, the Dadians, which was succeeded by a semi-independent dynasty, the Chikovans, who by 1838 had submitted to Russia, though they retained a nominal sovereignty. In 1866 the district was finally annexed by Russia.

COLCOTHAR (adapted in Romanic languages from Arabic _golgotar_, which was probably a corruption of the Gr. [Greek: chalkanthos], from [Greek: chalkos], copper, [Greek: anthos], flower, i.e. copper sulphate), a name given to the brownish-red ferric oxide formed in the preparation of fuming sulphuric (Nordhausen) acid by distilling ferrous sulphate. It is used as a polishing powder, forming the rouge of jewellers, and as the pigment Indian red. It is also known as _Crocus Martis_.

COLD (in O. Eng. _cald_ and _ceald_, a word coming ultimately from a root cognate with the Lat. _gelu_, _gelidus_, and common in the Teutonic languages, which usually have two distinct forms for the substantive and the adjective, cf. Ger. _Kälte_, _kalt_, Dutch _koude_, _koud_), subjectively the sensation which is excited by contact with a substance whose temperature is lower than the normal; objectively a quality or condition of material bodies which gives rise to that sensation. Whether cold, in the objective sense, was to be regarded as a positive quality or merely as absence of heat was long a debated question. Thus Robert Boyle, who does not commit himself definitely to either view, says, in his _New Experiments and Observations touching Cold_, that "the dispute which is the _primum frigidum_ is very well known among naturalists, some contending for the earth, others for water, others for the air, and some of the moderns for nitre, but all seeming to agree that there is some body or other that is of its own nature supremely cold and by participation of which all other bodies obtain that quality." But with the general acceptance of the dynamical theory of heat, cold naturally came to be regarded as a negative condition, depending on decrease in the amount of the molecular vibration that constitutes heat.

The question whether there is a limit to the degree of cold possible, and, if so, where the zero must be placed, was first attacked by the French physicist, G. Amontons, in 1702-1703, in connexion with his improvements in the air-thermometer. In his instrument temperatures were indicated by the height at which a column of mercury was sustained by a certain mass of air, the volume or "spring" of which of course varied with the heat to which it was exposed. Amontons therefore argued that the zero of his thermometer would be that temperature at which the spring of the air in it was reduced to nothing. On the scale he used the boiling-point of water was marked at 73 and the melting-point of ice at 51½, so that the zero of his scale was equivalent to about -240° on the centigrade scale. This remarkably close approximation to the modern value of -273° for the zero of the air-thermometer was further improved on by J. H. Lambert (_Pyrometrie_, 1779), who gave the value -270° and observed that this temperature might be regarded as absolute cold. Values of this order for the absolute zero were not, however, universally accepted about this period. Laplace and Lavoisier, for instance, in their treatise on heat (1780), arrived at values ranging from 1500° to 3000° below the freezing-point of water, and thought that in any case it must be at least 600° below, while John Dalton in his _Chemical Philosophy_ gave ten calculations of this value, and finally adopted -3000° C. as the natural zero of temperature. After J. P. Joule had determined the mechanical equivalent of heat, Lord Kelvin approached the question from an entirely different point of view, and in 1848 devised a scale of absolute temperature which was independent of the properties of any particular substance and was based solely on the fundamental laws of thermodynamics (see HEAT and THERMODYNAMICS). It followed from the principles on which this scale was constructed that its zero was placed at -273°, at almost precisely the same point as the zero of the air-thermometer.

In nature the realms of space, on the probable assumption that the interstellar medium is perfectly transparent and diathermanous, must, as was pointed out by W. J. Macquorn Rankine, be incapable of acquiring any temperature, and must therefore be at the absolute zero. That, however, is not to say that if a suitable thermometer could be projected into space it would give a reading of -273°. On the contrary, not being a transparent and diathermanous body, it would absorb radiation from the sun and other stars, and would thus become warmed. Professor J. H. Poynting ("Radiation in the Solar System," _Phil. Trans._, A, 1903, 202, p. 525) showed that as regards bodies in the solar system the effects of radiation from the stars are negligible, and calculated that by solar radiation alone a small absorbing sphere at the distance of Mercury from the sun would have its temperature raised to 483° Abs. (210° C), at the distance of Venus to 358° Abs. (85° C), of the earth to 300° Abs. (27° C), of Mars to 243° Abs. (-30° C), and of Neptune to only 54° Abs. (-219° C.). The French physicists of the early part of the 19th century held a different view, and rejected the hypothesis of the absolute cold of space. Fourier, for instance, postulated a fundamental temperature of space as necessary for the explanation of the heat-effects observed on the surface of the earth, and estimated that in the interplanetary regions it was little less than that of the terrestrial poles and below the freezing-point of mercury, though it was different in other parts of space (_Ann. chim. phys._, 1824, 27, pp. 141, 150). C. S. M. Pouillet, again, calculated the temperature of interplanetary space as -142° C. (_Comptes rendus_, 1838, 7, p. 61), and Sir John Herschel as -150° (_Ency. Brit._, 8th ed., art. "Meteorology," p. 643).

To attain the absolute zero in the laboratory, that is, to deprive a substance entirely of its heat, is a thermodynamical impossibility, and the most that the physicist can hope for is an indefinitely close approach to that point. The lowest steady temperature obtainable by the exhaustion of liquid hydrogen is about -262° C. (11° Abs.), and the liquefaction of helium by Professor Kamerlingh Onnes in 1908 yielded a liquid having a boiling-point of about 4.3° Abs., which on exhaustion must bring us to within about 2½ degrees of the absolute zero. (See LIQUID GASES.)

COLDEN, CADWALLADER (1688-1776), American physician and colonial official, was born at Duns, Scotland, on the 17th of February 1688. He graduated at the university of Edinburgh in 1705, spent three years in London in the study of medicine, and emigrated to America in 1708. After practising medicine for ten years in Philadelphia, he was invited to settle in New York by Governor Hunter, and in 1718 was appointed the first surveyor-general of the colony. Becoming a member of the provincial council in 1720, he served for many years as its president, and from 1761 until his death was lieutenant-governor; for a considerable part of the time, during the interim between the appointment of governors, he was acting-governor. About 1755 he retired from medical practice. As early as 1729 he had built a country house called Coldengham on the line between Ulster and Orange counties, where he spent much of his time until 1761. Aristocratic and extremely conservative, he had a violent distrust of popular government and a strong aversion to the popular party in New York. Naturally he came into frequent conflict with the growing sentiment in the colony in opposition to royal taxation. He was acting-governor when in 1765 the stamped paper to be used under the Stamp Act arrived in the port of New York; a mob burned him in effigy in his own coach in Bowling Green, in sight of the enraged acting-governor and of General Gage; and Colden was compelled to surrender the stamps to the city council, by whom they were locked up in the city hall until all attempts to enforce the new law were abandoned. Subsequently Colden secured the suspension of the provincial assembly by an act of parliament. He understood, however, the real temper of the patriot party, and in 1775, when the outbreak of hostilities seamed inevitable, he strongly advised the ministry to act with caution and to concede some of the colonists' demands. When the war began, he retired to his Long Island country seat, where he died on the 28th of September 1776. Colden was widely known among scientists and men of letters in England and America. He was a life-long student of botany, and was the first to introduce in America the classification system of Linnaeus, who gave the name "Coldenia" to a newly recognized genus. He was an intimate friend of Benjamin Franklin. He wrote several medical works of importance in their day, the most noteworthy being _A Treatise on Wounds and Fevers_ (1765); he also wrote _The History of the Five Indian Nations depending on the Province of New York_ (1727, reprinted 1866 and 1905), and an elaborate work on _The Principles of Action in Matter_ (1751) which, with his _Introduction to the Study of Physics_ (c. 1756), his _Enquiry into the Principles of Vital Motion_ (1766), and his _Reflections_ (c. 1770), mark him as the first of American materialists and one of the ablest material philosophers of his day. I. Woodbridge Riley, in _American Philosophy_ (New York, 1907), made the first critical study of Colden's philosophy, and said of it that it combined "Newtonian mechanics with the ancient hylozoistic doctrine ..." and "ultimately reached a kind of dynamic panpsychism, substance being conceived as a self-acting and universally diffused principle, whose essence is power and force."

See Alice M. Keys, _Cadwallader Colden, A Representative 18th Century Official_ (New York, 1906), a Columbia University doctoral dissertation; J. G. Mumford, _Narrative of Medicine in America_ (New York, 1903); and Asa Gray, "Selections from the Scientific Correspondence of Cadwallader Colden" in _American Journal of Science_, vol. 44, 1843.

His grandson, CADWALLADER DAVID COLDEN (1769-1834), lawyer and politician, was educated in London, but returned in 1785 to New York, where he attained great distinction at the bar. He was a colonel of volunteers during the war of 1812, and from 1818 to 1821 was the successor of Jacob Radcliff as mayor of New York City. He was a member of the state assembly (1818) and the state senate (1825-1827), and did much to secure the construction of the Erie Canal and the organization of the state public school system; and in 1821-1823 he was a representative in Congress. He wrote a _Life of Robert Fulton_ (1817) and a _Memoir of the Celebration of the Completion of the New York Canals_ (1825).

COLD HARBOR, OLD and NEW, two localities in Hanover county, Virginia, U.S.A., 10 m. N.E. of Richmond. They were the scenes of a succession of battles, on May 31-June 12, 1864, between the Union forces under command of General U. S. Grant and the Confederates under General R. E. Lee, who held a strongly entrenched line at New Cold Harbor. The main Union attack on June 3 was delivered by the II. (Hancock), VI. (Wright), and XVIII. (W. F. Smith) corps, and was brought to a standstill in eight minutes. An order from army headquarters to renew the attack was ignored by the officers and men at the front, who realized fully the strength of the hostile position. These troops lost as many as 5,000 men in an hour's fighting, the greater part in the few minutes of the actual assault. In the constant fighting of 31st of May to 12th of June on this ground Grant lost 14,000 men. (See WILDERNESS and AMERICAN CIVIL WAR.)

COLDSTREAM, a police burgh of Berwickshire, Scotland. Pop. (1901) 1482. It is situated on the north bank of the Tweed, here spanned by John Smeaton's fine bridge of five arches, erected in 1763-1766, 13½ m. south-west of Berwick by the North Eastern railway. The chief public buildings are the town hall, library, mechanics' institute, and cottage hospital. Some brewing is carried on. Owing to its position on the Border and also as the first ford of any consequence above Berwick, the town played a prominent part in Scottish history during many centuries. Here Edward I. crossed the stream in 1296 with his invading host, and Montrose with the Covenanters in 1640. Of the Cistercian priory, founded about 1165 by Cospatric of Dunbar, and destroyed by the 1st earl of Hertford in 1545, which stood a little to the east of the present market-place, no trace remains; but for nearly four hundred years it was a centre of religious fervour. Here it was that the papal legate, in the reign of Henry VIII., published a bull against the printing of the Scriptures; and by the irony of fate its site was occupied in the 19th century by an establishment, under Dr Adam Thomson, for the production of cheap Bibles. At Coldstream General Monk raised in 1659 the celebrated regiment of Foot Guards bearing its name. Like Gretna Green, Coldstream long enjoyed a notoriety as the resort of runaway couples, the old toll-house at the bridge being the usual scene of the marriage ceremony. "Marriage House," as it is called, still exists in good repair. Henry Brougham, afterwards lord chancellor, was married in this clandestine way, though in an inn and not at the bridge, in 1821. Birgham, 3 m. west, was once a place of no small importance, for there in 1188 William the Lion conferred with the bishop of Durham concerning the attempt of the English Church to impose its supremacy upon Scotland; there in 1289 was held the convention to consider the question of the marriage of the Maid of Norway with Prince Edward of England; and there, too, in 1290 was signed the treaty of Birgham, which secured the independence of Scotland. Seven miles below Coldstream on the English side, though 6 m. north-east of it, are the massive ruins of Norham Castle, made famous by Scott's _Marmion_, and from the time of its building by Ranulph Flambard in 1121 a focus of Border history during four centuries.

COLDWATER, a city and county-seat of Branch county, Michigan, U.S.A., on Coldwater Stream (which connects two of the group of small lakes in the vicinity), about 80 m. S.S.E. of Grand Rapids. Pop. (1890) 5247; (1900) 6216, of whom 431 were foreign-born; (1904) 6225; (1910) 5945. It is served by the Lake Shore & Michigan Southern railway. It is the seat of a state public school and temporary home (opened in 1874) for dependent, neglected or ill-treated children, who are received at any age under twelve. The city is situated in a fine farming region, has an important flouring and grist mill industry, and also manufactures Portland cement, liniment, lumber, furniture, sashes, doors and blinds, brass castings, sleighs, shoes, &c. The municipality owns and operates the water-works and electric lighting plant. Coldwater was settled in 1829, was laid out as a town under the name of Lyons in 1832, received its present name in the following year, was incorporated as a village in 1837, was reached by railway and became the county-seat in 1851, and was chartered as a city in 1861.

COLE, SIR HENRY (1808-1882), English civil servant, was born at Bath on the 15th of July 1808, and was the son of an officer in the army. At the age of fifteen he became clerk to Sir Francis Palgrave, then a subordinate officer in the record office, and, helped by Charles Buller, to whom he had been introduced by Thomas Love Peacock, and who became chairman of a royal commission for inquiry into the condition of the public records, worked his way up until he became an assistant keeper. He largely assisted in influencing public opinion in support of Sir Rowland Hill's reforms at the post office. A connexion with the Society of Arts caused him to drift gradually out of the record office: he was a leading member of the commission that organized the Great Exhibition of 1851, and upon the conclusion of its labours was made secretary to the School of Design, which by a series of transformations became in 1853 the Department of Science and Art. Under its auspices the South Kensington (now Victoria and Albert) Museum was founded in 1855 upon land purchased out of the surplus of the exhibition, and Cole practically became its director, retiring in 1873. His proceedings were frequently criticized, but the museum owes much to his energy. Indefatigable, genial and masterful, he drove everything before him, and by all sorts of schemes and devices built up a great institution, whose variety and inequality of composition seemed imaged in the anomalous structure in which it was temporarily housed. He also, though to the financial disappointment of many, conferred a great benefit upon the metropolis by originating the scheme for the erection of the Royal Albert Hall. He was active in founding the national training schools for cookery and music, the latter the germ of the Royal College of Music. He edited the works of his benefactor Peacock; and was in his younger days largely connected with the press, and the author of many useful topographical handbooks published under the pseudonym of "Felix Summerly." He died on the 18th of April 1882.

COLE, THOMAS (1801-1848), American landscape painter, was born at Bolton-le-Moors, England, on the 1st of February 1801. In 1819 the family emigrated to America, settling first in Philadelphia and then at Steubenville, Ohio, where Cole learned the rudiments of his profession from a wandering portrait painter named Stein. He went about the country painting portraits, but with little financial success. Removing to New York (1825), he displayed some landscapes in the window of an eating-house, where they attracted the attention of the painter Colonel Trumbull, who sought him out, bought one of his canvases, and found him patrons. From this time Cole was prosperous. He is best remembered by a series of pictures consisting of four canvases representing "The Voyage of Life," and another series of five canvases representing "The Course of Empire," the latter now in the gallery of the New York Historical Society. They were allegories, in the taste of the day, and became exceedingly popular, being reproduced in engravings with great success. The work, however, was meretricious, the sentiment false, artificial and conventional, and the artist's genuine fame must rest on his landscapes, which, though thin in the painting, hard in the handling, and not infrequently painful in detail, were at least earnest endeavours to portray the world out of doors as it appeared to the painter; their failings were the result of Cole's environment and training. He had an influence on his time and his fellows which was considerable, and with Durand he may be said to have founded the early school of American landscape painters. Cole spent the years 1829-1832 and 1841-1842 abroad, mainly in Italy, and at Florence lived with the sculptor Greenough. After 1827 he had a studio in the Catskills which furnished the subjects of some of his canvases, and he died at Catskill, New York, on the 11th of February 1848. His pictures are in many public and private collections. His "Expulsion from Eden" is in the Metropolitan Museum in New York.

COLE, TIMOTHY (1852- ), American wood engraver, was born in London, England, in 1852, his family emigrating to the United States in 1858. He established himself in Chicago, where in the great fire of 1871 he lost everything he possessed. In 1875 he removed to New York, finding work on the _Century_ (then _Scribner's_) magazine. He immediately attracted attention by his unusual facility and his sympathetic interpretation of illustrations and pictures, and his publishers sent him abroad in 1883 to engrave a set of blocks after the old masters in the European galleries. These achieved for him a brilliant success. His reproductions of Italian, Dutch, Flemish and English pictures were published in book form with appreciative notes by the engraver himself. Though the advent of new mechanical processes had rendered wood engraving almost a lost art and left practically no demand for the work of such craftsmen, Mr Cole was thus enabled to continue his work, and became one of the foremost contemporary masters of wood engraving. He received a medal of the first class at the Paris Exhibition of 1900, and the only grand prize given for wood engraving at the Louisiana Purchase Exposition at St Louis, Missouri, in 1904.

COLE, VICAT (1833-1893), English painter, born at Portsmouth on the 17th of April 1833, was the son of the landscape painter, George Cole, and in his practice followed his father's lead with marked success. He exhibited at the British Institution at the age of nineteen, and was first represented at the Royal Academy in 1853. His election as an associate of this institution took place in 1870, and he became an Academician ten years later. He died in London on the 6th of April 1893. The wide popularity of his work was due partly to the simple directness of his technical method, and partly to his habitual choice of attractive material. Most of his subjects were found in the counties of Surrey and Sussex, and along the banks of the Thames. One of his largest pictures, "The Pool of London," was bought by the Chantrey Fund Trustees in 1888, and is now in the Tate Gallery.

COLEBROOKE, HENRY THOMAS (1765-1837), English Orientalist, the third son of Sir George Colebrooke, 2nd baronet, was born in London on the 15th of June 1765. He was educated at home; and when only fifteen he had made considerable attainments in classics and mathematics. From the age of twelve to sixteen he resided in France, and in 1782 was appointed to a writership in India. About a year after his arrival there he was placed in the board of accounts in Calcutta; and three years later he was removed to a situation in the revenue department at Tirhut. In 1789 he was removed to Purneah, where he investigated the resources of that part of the country, and published his _Remarks on the Husbandry and Commerce of Bengal_, privately printed in 1795, in which he advocated free trade between Great Britain and India. After eleven years' residence in India, Colebrooke began the study of Sanskrit; and to him was confided the translation of the great _Digest of Hindu Laws_, which had been left unfinished by Sir William Jones. He translated the two treatises _Mitacshara_ and _Dayabhaga_ under the title _Law of Inheritance_. He was sent to Nagpur in 1799 on a special mission, and on his return was made a judge of the new court of appeal, over which he afterwards presided. In 1805 Lord Wellesley appointed him professor of Hindu Law and Sanskrit at the college of Fort William. During his residence at Calcutta he wrote his _Sanskrit Grammar_ (1805), some papers on the religious ceremonies of the Hindus, and his _Essay on the Vedas_ (1805), for a long time the standard work on the subject. He became member of council in 1807 and returned to England seven years later. He died on the 18th of March 1837. He was a director of the Asiatic Society, and many of the most valuable papers in the society's _Transactions_ were communicated by him.

His life was written by his son, Sir T. E. Colebrooke, in 1873.

COLEMANITE, a hydrous calcium borate, Ca2B6O11 + 5H2O, found in California as brilliant monoclinic crystals. It contains 50.9% of boron trioxide, and is an important source of commercial borates and boracic acid. Beautifully developed crystals, up to 2 or 3 in. in length, encrust cavities in compact, white colemanite; they are colourless and transparent, and the brilliant lustre of their faces is vitreous to adamantine in character. There is a perfect cleavage parallel to the plane of symmetry of the crystals. Hardness 4-4½; specific gravity 2.42. The mineral was first discovered in 1882 in Death Valley, Inyo county, California, and in the following year it was found in greater abundance near Daggett in San Bernardino county, forming with other borates and borosilicates a bed in sedimentary strata of sandstones and clays; in more recent years very large masses have been found and worked in these localities, and also in Los Angeles county (see Special Report, 1905, of U.S. Census Bureau on _Mines and Quarries_; and _Mineral Resources of the U.S._, 1907).

Priceite and pandermite are hydrous calcium borates with very nearly the same composition as colemanite, and they may really be only impure forms of this species. They are massive white minerals, the former friable and chalk-like, and the latter firm and compact in texture. Priceite occurs near Chetco in Curry county, Oregon, where it forms layers between a bed of slate and one of tough blue steatite; embedded in the steatite are rounded masses of priceite varying in size from that of a pea to masses weighing 200 lb. Pandermite comes from Asia Minor, and is shipped from the port of Panderma on the Sea of Marmora: it occurs as large nodules, up to a ton in weight, beneath a thick bed of gypsum.

Another borate of commercial importance found abundantly in the Californian deposits is ulexite, also known as boronatrocalcite or "cotton-ball," a hydrous calcium and sodium borate, CaNaB5O9 + 8H2O, which forms rounded masses consisting of a loose aggregate of fine fibres. It is the principal species in the borate deposits in the Atacama region of South America. (L. J. S.)

COLENSO, JOHN WILLIAM (1814-1883), English bishop of Natal, was born at St Austell, Cornwall, on the 24th of January 1814. His family were in embarrassed circumstances, and he was indebted to relatives for the means of university education. In 1836 he was second wrangler and Smith's prizeman at Cambridge, and in 1837 he became fellow of St John's. Two years later he went to Harrow as mathematical tutor, but the step proved an unfortunate one. The school was just then at the lowest ebb, and Colenso not only had few pupils, but lost most of his property by a fire. He went back to Cambridge, and in a short time paid off heavy debts by diligent tutoring and the proceeds of his series of manuals of algebra (1841) and arithmetic (1843), which were adopted all over England. In 1846 he became rector of Forncett St Mary, Norfolk, and in 1853 he was appointed bishop of Natal. He at once devoted himself to acquiring the Zulu language, of which he compiled a grammar and a dictionary, and into which he translated the New Testament and other portions of Scripture. He had already given evidence, in a volume of sermons dedicated to Maurice, that he was not satisfied with the traditional views about the Bible. The puzzling questions put to him by the Zulus strengthened him in this attitude and led him to make a critical examination of the Pentateuch. His conclusions, positive and negative, were published in a series of treatises on the Pentateuch, extending from 1862 to 1879, and, being in advance of his time, were naturally disputed in England with a fervour of conviction equal to his own. On the continent they attracted the notice of Abraham Kuenen, and furthered that scholar's investigations.

While the controversy raged in England, the South African bishops, whose suspicions Colenso had already incurred by the liberality of his views respecting polygamy among native converts and by a commentary upon the Epistle to the Romans (1861), in which he combated the doctrine of eternal punishment, met in conclave to condemn him, and pronounced his deposition (December 1863). Colenso, who had refused to appear before their tribunal otherwise than as sending a protest by proxy, appealed to the privy council, which pronounced that the metropolitan of Cape Town (Robert Gray) had no coercive jurisdiction and no authority to interfere with the bishop of Natal. No decision, therefore, was given upon the merits of the case. His adversaries, though unable to obtain his condemnation, succeeded in causing him to be generally inhibited from preaching in England, and Bishop Gray not only excommunicated him but consecrated a rival bishop for Natal (W. K. Macrorie), who, however, took his title from Maritzburg. The contributions of the missionary societies were withdrawn, but an attempt to deprive him of his episcopal income was frustrated by a decision of the courts. Colenso, encouraged by a handsome testimonial raised in England, to which many clergymen subscribed, returned to his diocese, and devoted the latter years of his life to further labours as a biblical commentator and translator. He also championed the cause of the natives against Boer oppression and official encroachments, a course by which he made more enemies among the colonists than he had ever made among the clergy. He died at Durban on the 20th of June 1883. His daughter Frances Ellen Colenso (1840-1887) published two books on the relations of the Zulus to the British (1880 and 1885), taking a pro-Zulu view; and an elder daughter, Harriette E. Colenso (b. 1847), became prominent as an advocate of the natives in opposition to their treatment by Natal, especially in the case of Dinizulu in 1888-1889 and in 1908-1909.

See his _Life_ by Sir G. W. Cox (2 vols., London, 1888).

COLENSO, a village of Natal on the right or south bank of the Tugela river, 16 m. by rail south by east of Ladysmith. It was the scene of an action fought on the 15th of December 1899 between the British forces under Sir Redvers Buller and the Boers, in which the former were repulsed. (See LADYSMITH.)

COLEOPTERA, a term used in zoological classification for the true beetles which form one of the best-marked and most natural of the orders into which the class Hexapoda (or Insecta) has been divided. For the relationship of the Coleoptera to other orders of insects see HEXAPODA. The name (Gr. [Greek: koleos], a sheath, and [Greek: ptera], wings) was first used by Aristotle, who noticed the firm protective sheaths, serving as coverings for the hind-wings which alone are used for flight, without recognizing their correspondence with the fore-wings of other insects.

These firm fore-wings, or elytra (fig. 1, A), are usually convex above, with straight hind margins (_dorsa_); when the elytra are closed, the two hind margins come together along the mid-dorsal line of the body, forming a _suture_. In many beetles the hind-wings are reduced to mere vestiges useless for flight, or are altogether absent, and in such cases the two elytra are often fused together at the suture; thus organs originally intended for flight have been transformed into an armour-like covering for the beetle's hind-body. In correlation with their heavy build and the frequent loss of the power of flight, many beetles are terrestrial rather than aerial in habit, though a large proportion of the order can fly well.

Aristotle's term was adopted by Linnaeus (1758), and has been universally used by zoologists. The identification of the elytra of beetles with the fore-wings of other insects has indeed been questioned (1880) by F. Meinert, who endeavoured to compare them with the tegulae of Hymenoptera, but the older view was securely established by the demonstration in pupal elytra by J. G. Needham (1898) and W. L. Tower (1903), of nervures similar to those of the hind-wing, and by the proof that the small membranous structures present beneath the elytra of certain beetles, believed by Meinert to represent the whole of the true fore-wings, are in reality only the alulae.

_Structure._--Besides the conspicuous character of the elytra, beetles are distinguished by the adaptation of the jaws for biting, the mandibles (fig. 1, Bb) being powerful, and the first pair of maxillae (fig. 1, Bc) usually typical in form. The maxillae of the second pair (fig. 1, Bd) are very intimately fused together to form what is called the "lower lip" or labium, a firm transverse plate representing the fused basal portions of the maxillae, which may carry a small median "ligula," representing apparently the fused inner maxillary lobes, a pair of paraglossae (outer maxillary lobes), and a pair of palps. The feelers of beetles differ greatly in the different families (cf. figs. 2b, 9b and 26b, c); the number of segments is usually eleven, but may vary from two to more than twenty.

The head is extended from behind forwards, so that the crown (epicranium) is large, while the face (clypeus) is small. The chin (gula) is a very characteristic sclerite in beetles, absent only in a few families, such as the weevils. There is usually a distinct labrum (fig. 1, Ba).

The prothorax is large and "free," i.e. readily movable on the mesothorax, an arrangement usual among insects with the power of rapid running. The tergite of the prothorax (pronotum) is prominent in all beetles, reaching back to the bases of the elytra and forming a substantial shield for the front part of the body. The tergal regions of the mesothorax and of the metathorax are hidden under the pronotum and the elytra when the latter are closed, except that the mesothoracic scutellum is often visible--a small triangular or semicircular plate between the bases of the elytra (fig. 1, A). The ventral region of the thoracic skeleton is complex, each segment usually possessing a median sternum with paired episterna (in front) and epimera (behind). The articular surfaces of the haunches (coxae) of the fore-legs are often conical or globular, so that each limb works in a ball-and-socket joint, while the hind haunches are large, displacing the ventral sclerites of the first two abdominal segments (fig. 1, C). The legs themselves (fig. 1, A) are of the usual insectan type, but in many families one, two, or even three of the five foot-segments may be reduced or absent. In beetles of aquatic habit the intermediate and hind legs are modified as swimming-organs (fig. 2, a), while in many beetles that burrow into the earth or climb about on trees the fore-legs are broadened and strengthened for digging, or lengthened and modified for clinging to branches. The hard fore-wings (elytra) are strengthened with marginal ridges, usually inflected ventrally to form epipleura which fit accurately along the edges of the abdomen. The upper surface of the elytron is sharply folded inwards at intervals, so as to give rise to a regular series of external longitudinal furrows (striae) and to form a set of supports between the two chitinous layers forming the elytron. The upper surface often shows a number of impressed dots (punctures). Along the sutural border of the elytron, the chitinous lamella forms a tubular space within which are numerous glands. The glands occur in groups, and lead into common ducts which open in several series along the suture. Sometimes the glands are found beneath the disk of the elytron, opening by pores on the surface. The hind-wings, when developed, are characteristic in form, possessing a sub-costal nervure with which the reduced radial nervure usually becomes associated. There are several curved median and cubital nervures and a single anal, but few cross nervures or areolets. The wing, when not in use, is folded both lengthwise and transversely, and doubled up beneath the elytron; to permit the transverse folding, the longitudinal nervures are interrupted.

Ten segments can be recognized--according to the studies of K. W. Verhoeff (1804-1896)--in a beetle's abdomen, but the tenth sternite is usually absent. On account of the great extension of the metathorax and the haunches of the large hind-legs, the first abdominal sternite is wanting, and the second is usually so much reduced that the foremost apparent ventral sclerite of the abdomen represents the third sternite. From this point backwards the successive abdominal segments, as far as the seventh or eighth, can be readily made out. The ninth and tenth segments are at most times retracted within the eighth. The female can protrude a long flexible tube in connexion with the eighth segment, carrying the sclerites of the ninth at its extremity, and these sclerites may carry short hairy processes--the stylets. This flexible tube is the functional ovipositor, the typical insectan ovipositor with its three pairs of processes (see HEXAPODA) being undeveloped among the Coleoptera. In male beetles, however, the two pairs of genital processes (paramera) belonging to the ninth abdominal segment are always present, though sometimes reduced. Between them is situated, sometimes asymmetrically, the prominent intromittent organ.

In the structure of the digestive system, beetles resemble most other mandibulate insects, the food-canal consisting of gullet, crop, gizzard, mid-gut or stomach, intestine and rectum. The stomach is beset throughout its length with numerous small, finger-like caecal tubes. The excretory (malpighian) tubes are few in number, either four or six. Many beetles have, in connexion with the anus, glands which secrete a repellent acid fluid, serving as a defence for the insect when attacked. The "bombardier" ground beetles (fig. 5) have this habit. Oil-beetles (figs. 23 and 24) and ladybirds (fig. 32) defend themselves by ejecting drops of fluid from the knee-joints. The nervous system is remarkably concentrated in some beetles, the abdominal ganglia showing a tendency to become shifted forward and crowded together, and in certain chafers all the thoracic and abdominal ganglia are fused into a single nerve-centre situated in the thorax,--a degree of specialization only matched in the insectan class among the Hemiptera and some muscid flies.

_Development._--The embryonic development (see HEXAPODA) has been carefully studied in several genera of beetles. As regards growth after hatching, all beetles undergo a "complete" metamorphosis, the wing-rudiments developing beneath the cuticle throughout the larval stages, and a resting pupal stage intervening between the last larval instar[1] and the imago. The coleopterous pupa (figs. 2d, 3c) is always "free," the legs, wings and other appendages not being fixed to the body as in the pupa of a moth, and the likeness of pupa to perfect insect is very close.

The most striking feature in the development of beetles is the great diversity noticeable in the outward form of the larva in different families. The larva of a ground-beetle or a carnivorous water-beetle (fig. 2 c) is an active elongate grub with well-armoured cuticle. The head--carrying feelers, mandibles and two pairs of maxillae--is succeeded by the three thoracic segments, each bearing a pair of strong five-segmented legs, whose feet, like those of the adult, carry two claws. Ten segments can be distinguished in the tapering abdomen, the ninth frequently bearing a pair of tail-feelers (cerci), and the tenth, attached ventrally to the ninth, having the anal opening at its extremity and performing the function of a posterior limb, supporting and temporarily fixing the tail end of the insect on the surface over which it crawls. Such a typically "campodeiform" grub, moving actively about in pursuit of prey, is the one extreme of larval structure to be noticed among the Coleoptera. The other is exemplified by the white, wrinkled, soft-skinned, legless grub of a weevil, which lives underground feeding on roots, or burrows in the tissues of plants (fig. 3 b). Between these two extremes we find various transitional forms: an active larva, as described above, but with four-segmented, single-clawed legs, as among the rove-beetles and their allies; the body well armoured, but slender and worm-like, with very short legs as in wireworms and mealworms (figs. 18, 21 b); the body shortened, with the abdomen swollen, but protected with tubercles and spines, and with longish legs adapted for an active life, as in the predaceous larvae of ladybirds; the body soft-skinned, swollen and caterpillar-like, with legs well developed, but leading a sluggish underground life, as in the grub of a chafer; the body soft-skinned and whitish, and the legs greatly reduced in size, as in the wood-feeding grub of a longhorn beetle. In the case of certain beetles whose larvae do not find themselves amid appropriate food from the moment of hatching, but have to migrate in search of it, an early larval stage, with legs, is followed by later sluggish stages in which legs have disappeared, furnishing examples of what is called hypermetamorphosis. For example, the grub of a pea or bean beetle (_Bruchus_) is hatched, from the egg laid by its mother on the carpel of a leguminous flower, with three pairs of legs and spiny processes on the prothorax. It bores through and enters the developing seed, where it undergoes a moult and becomes legless. Similarly the newly-hatched larva of an oil-beetle (_Meloe_) is an active little campodeiform insect, which, hatched from an egg laid among plants, waits to attach itself to a passing bee. Carried to the bee's nest, it undergoes a moult, and becomes a fat-bodied grub, ready to lead a quiet life feeding on the bee's rich food-stores.

_Distribution and Habits._--The Coleoptera are almost world-wide in their distribution, being represented in the Arctic regions and on almost all oceanic islands. Most of the dominant families--such as the _Carabidae_ (ground-beetles), _Scarabaeidae_ (chafers), or _Curculionidae_ (weevils) have a distribution as wide as the order. But while some large families, such as the _Staphylinidae_ (rove-beetles) are especially abundant on the great northern continents, becoming scarcer in the tropics, others, the _Cicindelidae_ (tiger-beetles), for example, are most strongly represented in the warmer regions of the earth, and become scarce as the collector journeys far to south or north. The distribution of many groups of beetles is restricted in correspondence with their habits; the _Cerambycidae_ (longhorns), whose larvae are wood-borers, are absent from timberless regions, and most abundant in the great tropical forests. Some families are very restricted in their range. The _Amphizoidae_, for example, a small family of aquatic beetles, are known only from western North America and Eastern Tibet, while an allied family, the _Pelobiidae_, inhabit the British Isles, the Mediterranean region, Tibet and Australia. The beetles of the British islands afford some very interesting examples of restricted distribution among species. For example, large and conspicuous European beetles, such as the stag-beetle (fig. 1, _Lucanus cervus_) and the great water-beetle (_Hydrophilus piceus_, fig. 20), are confined to eastern and southern Britain, and are unknown in Ireland. On the other hand, there are Arctic species like the ground-beetle, _Pelophila borealis_, and south-western species like the boring weevil, _Mesites Tardyi_, common in Ireland, and represented in northern or western Britain, but unknown in eastern Britain or in Central Europe. Careful study of insular faunas, such as that of Madeira by T. V. Wollaston, and of the Sandwich Islands by D. Sharp, and the comparison of the species found with those of the nearest continental land, furnish the student of geographical distribution with many valuable and suggestive facts.

Notes on habit are given below in the accounts of the various families. In general it may be stated that beetles live and feed in almost all the diverse ways possible for insects. There are carnivores, herbivores and scavengers among them. Various species among those that are predaceous attack smaller insects, hunt in packs crustaceans larger than themselves, insert their narrow heads into snail-shells to pick out and devour the occupants, or pursue slugs and earthworms underground. The vegetable-feeders attack leaves, herbaceous or woody stems and roots; frequently different parts of a plant are attacked in the two active stages of the life-history; the cockchafers, for example, eating leaves, and their grubs gnawing roots. Some of the scavengers, like the burying beetles, inter the bodies of small vertebrates to supply food for themselves and their larvae, or, like the "sacred" beetle of Egypt, collect for the same purpose stores of dung. Many beetles of different families have become the "unbidden guests" of civilized man, and may be found in dwelling-houses, stores and ships' cargoes, eating food-stuffs, paper, furniture, tobacco and drugs. Hence we find that beetles of some kind can hold their own anywhere on the earth's surface. Some climb trees and feed on leaves, while others tunnel between bark and wood. Some fly through the air, others burrow in the earth, while several families have become fully adapted to life in fresh water. A large number of beetles inhabit the deep limestone caves of Europe and North America, while many genera and some whole families are at home nowhere but in ants' nests. Most remarkable is the presence of a number of beetles along the seashore between tide-marks, where, sheltered in some secure nook, they undergo immersion twice daily, and have their active life confined to the few hours of the low ebb.

_Stridulating Organs._--Many beetles make a hissing or chirping sound by rubbing a "scraper," formed by a sharp edge or prominence on some part of their exoskeleton, over a "file" formed by a number of fine ridges situate on an adjacent region. These stridulating organs were mentioned by C. Darwin as probable examples of the action of sexual selection; they are, however, frequently present in both sexes, and in some families also in the larvae. An account of the principal types of stridulators that have been described has been published by C. J. Gahan (1900). The file may be on the head--either upper or lower surface--and the scraper formed by the front edge of the prothorax, as in various wood-boring beetles (_Anobium_ and _Scolytus_). Or ridged areas on the sides of the prothorax may be scraped by "files" on the front thighs, as in some ground-beetles. Among the longhorn beetles, the prothorax scrapes over a median file on the mid-dorsal aspect of the mesothorax. In a large number of beetles of different families, stridulating areas occur on various segments of the abdomen, and are scraped by the elytra. It is remarkable that these organs are found in similar positions in genera belonging to widely divergent families, while two genera of the same family may have them in different positions. It follows, therefore, that they have been independently acquired in the course of the evolution of the Coleoptera.

Stridulating organs among beetle-larvae have been noted, especially in the wood-feeding grub of the stag-beetles (_Lucanidae_) and their allies the _Passalidae_, and in the dung-eating grubs of the dor-beetles (_Geotrupes_), which belong to the chafer family (_Scarabaeidae_). These organs are described by J. C. Schiödte and D. Sharp; in the stag-beetle larva a series of short tubercles on the hind-leg is drawn across the serrate edge of a plate on the haunch of the intermediate legs, while in the Passalid grub the modified tip of the hind-leg acts as a scraper, being so shortened that it is useless for locomotion, but highly specialized for producing sound. Whatever may be the true explanation of stridulating organs in adult beetles, sexual selection can have had nothing to do with the presence of these highly-developed larval structures. It has been suggested that the power of stridulation would be advantageous to wood-boring grubs, the sound warning each of the position of its neighbour, so that adjacent burrowers may not get in each other's way. The root-feeding larvae of the cockchafer and allied members of the _Scarabaeidae_ have a ridged area on the mandible, which is scraped by teeth on the maxillae, apparently forming a stridulating organ.

_Luminous Organs._--The function of the stridulating organs just described is presumably to afford means of recognition by sound. Some beetles emit a bright light from a portion of their bodies, which leads to the recognition of mate or comrade by sight. In the wingless female glow-worm (_Lampyris_, fig. 15 f) the luminous region is at the hinder end, the organ emitting the light consisting, according to H. von Wielowiejski (1882), of cells similar to those of the fat-body, containing a substance that undergoes oxidation. The illumination is intermittent, and appears to be under the control of the insect's nervous system. The well-known "fire-flies" of the tropics are large click-beetles (_Elateridae_), that emit light from paired spots on the prothorax and from the base of the ventral abdominal region. The luminous organs of these beetles consist of a specialized part of the fat-body, with an inner opaque and an outer transparent layer. Its structure has been described by C. Heinemann, and its physiology by R. Dubois (1886), who considers that the luminosity is due to the influence of an enzyme in the cells of the organ upon a special substance in the blood. The eggs and larvae of the fire-flies are luminous as well as the perfect beetles.

_Fossil History._--The Coleoptera can be traced back farther in time than any other order of insects with complete transformations, if the structures that have been described from the Carboniferous rocks of Germany are really elytra. In the Triassic rocks of Switzerland remains of weevils (_Curculionidae_) occur, a family which is considered by many students the most specialized of the order. And when we know that the _Chrysomelidae_ and _Buprestidae_ also lived in Triassic, and the _Carabidae_, _Elateridae_, _Cerambycidae_ and _Scarabaeidae_, in Liassic times, we cannot doubt that the great majority of our existing families had already been differentiated at the beginning of the Mesozoic epoch. Coming to the Tertiary we find the Oligocene beds of Aix, of east Prussia (amber) and of Colorado, and the Miocene of Bavaria, especially rich in remains of beetles, most of which can be referred to existing genera.

_Classification._--The Coleoptera have been probably more assiduously studied by systematic naturalists than any other order of insects. The number of described species can now hardly be less than 100,000, but there is little agreement as to the main principles of a natural classification. About eighty-five families are generally recognized; the difficulty that confronts the zoologists is the arrangement of these families in "superfamilies" or "sub-orders." Such obvious features as the number of segments in the foot and the shape of the feeler were used by the early entomologists for distinguishing the great groups of beetles. The arrangement dependent on the number of tarsal segments--the order being divided into tribes _Pentamera_, _Tetramera_, _Heteromera_ and _Trimera_--was suggested by E. L. Geoffroy in 1762, adopted by P. A. Latreille, and used largely through the 19th century. W. S. Macleay's classification (1825), which rested principally on the characters of the larvae, is almost forgotten nowadays, but it is certain that in any systematic arrangement which claims to be natural the early stages in the life-history must receive due attention. In recent years classifications in part agreeing with the older schemes but largely original, in accord with researches on the comparative anatomy of the insects, have been put forward. Among the more conservative of these may be mentioned that of D. Sharp (1899), who divides the order into six great series of families: _Lamellicornia_ (including the chafers and stag-beetles and their allies with five-segmented feet and plate-like terminal segments to the feelers); _Adephaga_ (carnivorous, terrestrial and aquatic beetles, all with five foot-segments); _Polymorpha_ (including a heterogeneous assembly of families that cannot be fitted into any of the other groups); _Heteromera_ (beetles with the fore and intermediate feet five-segmented, and the hind-feet four-segmented); _Phytophaga_ (including the leaf-beetles, and longhorns, distinguished by the apparently four-segmented feet), and _Rhynchophora_ (the weevils and their allies, with head prolonged into a snout, and feet with four segments). L. Ganglbauer (1892) divides the whole order into two sub-orders only, the _Caraboidea_ (the _Adephaga_ of Sharp and the older writers) and the _Cantharidoidea_ (including all other beetles), since the larvae of _Caraboidea_ have five-segmented, two-clawed legs, while those of all other beetles have legs with four segments and a single claw. A. Lameere (1900) has suggested three sub-orders, the _Cantharidiformia_ (including the _Phytophaga_, the _Heteromera_, the _Rhynchophora_ and most of the _Polymorpha_ of Sharp's classification), the _Staphyliniformia_ (including the rove-beetles, carrion-beetles and a few allied families of Sharp's _Polymorpha_), and the _Carabidiformia_ (_Adephaga_). Lameere's classification is founded on the number of abdominal sterna, the nervuration of the wings, the number of malpighian tubules (whether four or six) and other structural characters. Preferable to Lameere's system, because founded on a wider range of adult characters and taking the larval stages into account, is that of H. J. Kolbe (1901), who recognizes three sub-orders: (i.) the _Adephaga_; (ii.) the _Heterophaga_, including the _Staphylinoidea_, the _Actinorhabda_ (_Lamellicornia_), the _Heterorhabda_ (most of Sharp's _Polymorpha_), and the _Anchistopoda_ (the _Phytophaga_, with the ladybirds and some allied families which Sharp places among the _Polymorpha_); (iii.) the _Rhynchophora_.

Students of the Coleoptera have failed to agree not only on a system of classification, but on the relative specialization of some of the groups which they all recognize as natural. Lameere, for example, considers some of his _Cantharidiformia_ as the most primitive Coleoptera. J. L. Leconte and G. H. Horn placed the _Rhynchophora_ (weevils) in a group distinct from all other beetles, on account of their supposed primitive nature. Kolbe, on the other hand, insists that the weevils are the most modified of all beetles, being highly specialized as regards their adult structure, and developing from legless maggots exceedingly different from the adult; he regards the Adephaga, with their active armoured larvae with two foot-claws, as the most primitive group of beetles, and there can be little doubt that the likeness between larvae and adult may safely be accepted as a primitive character among insects. In the Coleoptera we have to do with an ancient yet dominant order, in which there is hardly a family that does not show specialization in some point of structure or life-history. Hence it is impossible to form a satisfactory linear series.

In the classification adopted in this article, the attempt has been made to combine the best points in old and recent schemes, and to avoid the inconvenience of a large heterogeneous group including the vast majority of the families.

ADEPHAGA.--This tribe includes beetles of carnivorous habit with five segments on every foot, simple thread-like feelers with none of the segments enlarged to form club or pectination, and the outer lobs (galea) of the first maxilla usually two-segmented and palpiform (fig. 4 b). The transverse fold of the hind-wing is towards the tip, about two-thirds of the wing-length from the base. At this fold the median nervure stops and is joined by a cross nervure to the radial, which can be distinguished throughout its length from the subcostal. There are four malpighian tubules. In the ovarian tubes of Adephaga small yolk-chambers alternate with the egg-chambers, while in all other beetles there is only a single large yolk-chamber at the narrow end of the tube. The larvae (fig. 2 c) are active, with well-chitinized cuticle, often with elongate tail-feelers (cerci), and with five-segmented legs, the foot-segment carrying two claws.

The generalized arrangement of the wing-nervure and the nature of the larva, which is less unlike the adult than in other beetles, distinguish this tribe as primitive, although the perfect insects are, in the more dominant families, distinctly specialized. Two very small families of aquatic beetles seem to stand at the base of the series, the _Amphizoidae_, whose larvae are broad and well armoured with short cerci, and the _Pelobiidae_, which have elongate larvae, tapering to the tail end, where are long paired cerci and a median process, recalling the grub of a Mayfly.

The _Dyticidae_ (fig. 2) are Adephaga highly specialized for life in the water, the hind-legs having the segments short, broad and fringed, so as to be well adapted for swimming, and the feet without claws. The metasternum is without the transverse linear impression that is found in most families of Adephaga. The beetles are ovoid in shape, with smooth contours, and the elytra fit over the edges of the abdomen so as to enclose a supply of air, available for use when the insect remains under water. The fore-legs of many male dyticids have the three proximal foot-segments broad and saucer-shaped, and covered with suckers, by means of which they secure a firm hold of their mates. Larval dyticids (fig. 2 b) possess slender, curved, hollow mandibles, which are perforated at the tip and at the base, being thus adapted for sucking the juices of victims. Large dyticid larvae often attack small fishes and tadpoles. They breathe by piercing the surface film with the tail, where a pair of spiracles are situated. The pupal stage is passed in an earthen cell, just beneath the surface of the ground. Nearly 2000 species of _Dyticidae_ are known: they are universally distributed, but are most abundant in cool countries. The _Haliplidae_ form a small aquatic family allied to the _Dyticidae_.

The _Carabidae_, or ground-beetles, comprising 13,000 species, form the largest and most typical family of the Adephaga (figs. 4, 5, 6), the legs of all three pairs being alike and adapted for rapid running. In many _Carabidae_ the hind-wings are reduced or absent, and the elytra fused together along the suture. Many of our native species spend the day lurking beneath stones, and sally forth at night in pursuit of their prey, which consists of small insects, earthworms and snails. But a number of the more brightly coloured ground-beetles run actively in the sunshine. The carabid larva is an active well-armoured grub with the legs and cerci variable in length. Great differences in the general form of the body may be observed in the family. For example, the stout, heavy body of _Carabus_ (fig. 6) contrasts markedly with the wonderful flattened abdomen and elytra of _Mormolyce_ (fig. 4), a Malayan genus found beneath fallen trees, a situation for which its compressed shape is admirably adapted. Blind _Carabidae_ form a large proportion of cave-dwelling beetles, and several species of great interest live between tide-marks along the seashore.

The _Cicindelidae_, or tiger-beetles (figs. 7, 8) are the most highly organized of all the Adephaga. The inner lobe (lacinia) of the first maxilla terminates in an articulated hook, while in the second maxillae (labium) both inner and outer lobes ("ligula" and "para-glossae") are much reduced. The face (clypeus) is broad, extending on either side in front of the insertion of the feelers. The beetles are elegant insects with long, slender legs, running quickly, and flying in the sunshine. The pronotum and elytra are often adorned with bright colours or metallic lustre, and marked with stripes or spots. The beetles are fierce in nature and predaceous in habit, their sharp toothed mandibles being well adapted for the capture of small insect-victims. The larvae are more specialized than those of other Adephaga, the head and prothorax being very large and broad, the succeeding segments slender and incompletely chitinized. The fifth abdominal segment has a pair of strong dorsal hook-like processes, by means of which the larva supports itself in the burrow which it excavates in the earth, the great head blocking the entrance with the mandibles ready to seize on any unwary insect that may venture within reach.

Two or three families may be regarded as aberrant Adephaga. The _Paussidae_ are a very remarkable family of small beetles, mostly tropical, found only in ants' nests, or flying by night, and apparently migrating from one nest to another. The number of antennal segments varies from eleven to two. It is supposed that these beetles secrete a sweet substance on which the ants feed, but they have been seen to devour the ants' eggs and grubs. The _Gyrinidae_, or whirligig beetles (fig. 9), are a curious aquatic family with the feelers (fig. 9, b) short and reduced as in most _Paussidae_. They are flattened oval in form, circling with gliding motion over the surface film of the water, and occasionally diving, when they carry down with them a bubble of air. The fore-legs are elongate and adapted for clasping, while the short and flattened intermediate and hind legs form very perfect oar-like propellers. The larva of _Gyrinus_ (fig. 9, c) is slender with elongate legs, and the abdominal segments carry paired tracheal gills.

STAPHYLINOIDEA.--The members of this tribe may be easily recognized by their wing-nervuration. Close to a transverse fold near the base of the wing, the median nervure divides into branches which extend to the wing-margin; there is a second transverse fold near the tip of the wing, and cross nervures are altogether wanting. There are four malpighian tubes, and all five tarsal segments are usually recognizable. With very few exceptions, the larva in this group is active and campodeiform, with cerci and elongate legs as in the Adephaga, but the leg has only four segments and one claw.

The _Silphidae_, or carrion beetles, form one of the best-known families of this group. They are rotund or elongate insects with conical front haunches, the elytra generally covering (fig. 10) the whole dorsal region of the abdomen, but sometimes leaving as many as four terga exposed (fig. 11). Some of these beetles are brightly coloured, while others are dull black. They are usually found in carrion, and the species of _Necrophorus_ (fig. 11) and _Necrophaga_ are valuable scavengers from their habit of burying small vertebrate carcases which may serve as food for their larvae. At this work a number of individuals are associated together. The larvae that live underground have spiny dorsal plates, while those of the _Silpha_ (fig. 10) and other genera that go openly about in search of food resemble wood-lice. About 1000 species of _Silphidae_ are known. Allied to the _Silphidae_ are a number of small and obscure families, for which reference must be made to monographs of the order. Of special interest among these are the _Histeridae_, compact beetles (fig. 12) with very hard cuticle and somewhat abbreviated elytra, with over 2000 species, most of which live on decaying matter, and the curious little _Pselaphidae_, with three-segmented tarsi, elongate palpi, and shortened abdomen; the latter are usually found in ants' nests, where they are tended by the ants, which take a sweet fluid secreted among little tufts of hair on the beetles' bodies; these beetles, which are carried about by the ants, sometimes devour their larvae. The _Trichopterygidae_, with their delicate narrow fringed wings, are the smallest of all beetles, while the _Platypsyllidae_ consist of only a single species of curious form found on the beaver.

The _Staphylinidae_, or rove-beetles--a large family of nearly 10,000 species--may be known by their very short elytra, which cover only two of the abdominal segments, leaving the elongate hind-body with seven or eight exposed, firm terga (figs. 13, 14). These segments are very mobile, and as the rove-beetles run along they often curl the abdomen upwards and forwards like the tail of a scorpion. The _Staphylinid_ larvae are typically campodeiform. Beetles and larvae are frequently carnivorous in habit, hunting for small insects under stones, or pursuing the soft-skinned grubs of beetles and flies that bore in woody stems or succulent roots. Many _Staphylinidae_ are constant inmates of ants' nests.

MALACODERMATA.--In this tribe may be included a number of families distinguished by the softness of the cuticle, the presence of seven or eight abdominal sterna and of four malpighian tubes, and the firm, well-armoured larva (fig. 15, c) which is often predaceous in habit. The mesothoracic epimera bound the coxal cavities of the intermediate legs. The _Lymexylonidae_, a small family of this group, characterized by its slender, undifferentiated feelers and feet, is believed by Lameere to comprise the most primitive of all living beetles, and Sharp lays stress on the undeveloped structure of the tribe generally.

The _Lampyridae_ are a large family, of which the glow-worm (_Lampyris_) and the "soldier beetles" (_Telephorus_) are familiar examples. The female "glow-worm" (fig. 15, b), emitting the well-known light (see above), is wingless and like a larva; the luminosity seems to be an attraction to the male, whose eyes are often exceptionally well developed. Some male members of the family have remarkably complex feelers. In many genera of _Lampyridae_ the female can fly as well as the male; among these are the South European "fireflies."

TRICHODERMATA.--Several families of rather soft-skinned beetles, such as the _Melyridae_, _Cleridae_ (fig. 16), _Corynetidae_, _Dermestidae_ (fig. 17), and _Dascillidae_, are included in this tribe. They may be distinguished from the Malacodermata by the presence of only five or six abdominal sterna, while six malpighian tubes are present in some of the families. The beetles are hairy and their larvae well-armoured and often predaceous. Several species of _Dermestidae_ are commonly found in houses, feeding on cheeses, dried meat, skins and other such substances. The "bacon beetle" (_Dermestes lardarius_), and its hard hairy larva, are well known. According to Sharp, all Dermestid larvae probably feed on dried animal matters; he mentions one species that can find sufficient food in the horsehair of furniture, and another that eats the dried insect-skins hanging in old cobwebs.

STERNOXIA.--This is an important tribe of beetles, including families with four malpighian tubes and only five or six abdominal sterna, while in the thorax there is a backwardly directed process of the prosternum that fits into a mesosternal cavity. The larvae are elongate and worm-like, with short legs but often with hard strong cuticle.

The _Elateridae_ or click beetles (fig. 18) have the prosternal process just mentioned, capable of movement in and out of the mesosternal cavity, the beetles being thus enabled to leap into the air, hence their popular name of "click-beetles" or "skip-jacks." The prothorax is convex in front, and is usually drawn out behind into a prominent process on either side, while the elytra are elongate and tapering. Many of the tropical American _Elateridae_ emit light from the spots on the prothorax and an area beneath the base of the abdomen; these are "fireflies" (see above). The larvae of _Elateridae_ are elongate, worm-like grubs, with narrow bodies, very firm cuticle, short legs, and a distinct anal proleg. They are admirably adapted for moving through the soil, where some of them live on decaying organic matter, while others are predaceous. Several of the elaterid larvae, however, gnaw roots and are highly destructive to farm crops. These are the well-known "wire-worms" (q.v.).

The _Buprestidae_ are distinguished from the _Elateridae_ by the immobility of the prosternal process in the mesosternal cavity and by the absence of the lateral processes at the hind corners of the prothorax. Many tropical _Buprestidae_ are of large size (fig. 19), and exhibit magnificent metallic colours; their elytra are used as ornaments in human dress. The larvae are remarkable for their small head, very broad thorax, with reduced legs, and narrow elongate abdomen. They feed by burrowing in the roots and stems of plants.

BOSTRYCHOIDEA.--This tribe is distinguished from the Malacoderma and allied groups by the mesothoracic epimera not bounding the coxal cavities of the intermediate legs. The downwardly directed head is covered by the pronotum, and the three terminal antennal segments form a distinct club. To this group belong the _Bostrychidae_ and _Ptinidae_, well known (especially the latter family) for their ravages in old timber. The larvae are stout and soft-skinned, with short legs in correlation with their burrowing habit. The noises made by some _Ptinidae_ (_Anobium_) tapping on the walls of their burrows with their mandibles give rise to the "death tick" that has for long alarmed the superstitious.

CLAVICORNIA.--This is a somewhat heterogeneous group, most of whose members are characterized by clubbed feelers and simple, unbroadened tarsal segments--usually five on each foot--but in some families and genera the males have less than the normal number on the feet of one pair. There are either four or six malpighian tubes. A large number of families, distinguished from each other by more or less trivial characters, are included here, and there is considerable diversity in the form of the larvae. The best-known family is the _Hydrophilidae_, in which the feelers are short with less than eleven segments and the maxillary palpi very long. Some members of this family--the large black _Hydrophilus piceus_ (fig. 20), for example--are specialized for an aquatic life, the body being convex and smooth as in the _Dyticidae_, and the intermediate and hind-legs fringed for swimming. When _Hydrophilus_ dives it carries a supply of air between the elytra and the dorsal surface of the abdomen, while air is also entangled in the pubescence which extends beneath the abdomen on either side, being scooped in bubbles by the terminal segments of the feelers when the insect rises to the surface. Many of the _Hydrophilidae_ construct, for the protection of their eggs, a cocoon formed of a silky material derived from glands opening at the tip of the abdomen. That of _Hydrophilus_ is attached to a floating leaf, and is provided with a hollow, tapering process, which projects above the surface and presumably conveys air to the enclosed eggs. Other _Hydrophilidae_ carry their egg-cocoons about with them beneath the abdomen. Many _Hydrophilidae_, unmodified for aquatic life, inhabit marshes. The larvae in this family are well-armoured, active and predaceous. Of the numerous other families of the Clavicornia may be mentioned the _Cucujidae_ and _Cryptophagidae_, small beetles, examples of which may be found feeding on stored seeds or vegetable refuse, and the _Mycetophagidae_, which devour fungi. The _Nitidulidae_ are a large family with 1600 species, among which members of the genus _Meligethes_ are often found in numbers feeding on blossoms, while others live under the bark of trees and prey on the grubs of boring beetles.

HETEROMERA.--This tribe is distinguished by the presence of the normal five segments in the feet of the fore and intermediate legs, while only four segments are visible in the hind-foot. Considerable diversity is to be noticed in details of structure within this group, and for an enumeration of all the various families which have been proposed and their distinguishing characters the reader is referred to one of the monographs mentioned below. Some of the best-known members of the group belong to the _Tenebrionidae_, a large family containing over 10,000 species and distributed all over the world. The tenebrionid larva is elongate, with well-chitinized cuticle, short legs and two stumpy tail processes, the common mealworm (fig. 21) being a familiar example. Several species of this family are found habitually in stores of flour or grain. The beetles have feelers with eleven segments, whereof the terminal few are thickened so as to form a club. The true "black-beetles" or "churchyard beetles" (_Blaps_) (fig. 22) belong to this family; like members of several allied genera they are sooty in colour, and somewhat resemble ground beetles (_Carabi_) in general appearance.

The most interesting of the Heteromera, and perhaps of all the Coleoptera, are some beetles which pass through two or more larval forms in the course of the life-history (hypermetamorphosis). These belong to the families _Rhipidophoridae_ and _Meloidae_. The latter are the oil beetles (fig. 23) or blister beetles (fig. 24), insects with rather soft cuticle, the elytra (often abbreviated) not fitting closely to the sides of the abdomen, the head constricted behind the eyes to form a neck, and the claws of the feet divided to the base. Several of the _Meloidae_ (such as the "Spanish fly," fig. 24) are of economic importance, as they contain a vesicant substance used for raising medicinal blisters on the human skin. The wonderful transformations of these insects were first investigated by G. Newport in 1851, and have recently been more fully studied by C. V. Riley (1878) and J. H. Fabre. The first larval stage is the "triungulin," a tiny, active, armoured larva with long legs (each foot with three claws) and cercopods. In the European species of _Sitaris_ and _Meloe_ these little larvae have the instinct of clinging to any hairy object. All that do not happen to attach themselves to a bee of the genus _Anthophora_ perish, but those that succeed in reaching the right host are carried to the nest, and as the bee lays an egg in the cell the triungulin slips off her body on to the egg, which floats on the surface of the honey. After eating the contents of the egg, the larva moults and becomes a fleshy grub with short legs and with paired spiracles close to the dorsal region, so that, as it floats in and devours the honey, it obtains a supply of air. After a resting (pseudo-pupal) stage and another larval stage, the pupa is developed. In the American EPICAUTA VITTATA the larva is parasitic on the eggs and egg-cases of a locust. The triungulin searches for the eggs, and, after a moult, becomes changed into a soft-skinned tapering larva. This is followed by a resting (pseudo-pupal) stage, and this by two successive larval stages like the grub of a chafer. The RHIPIDOPHORIDAE are beetles with, short elytra, the feelers pectinate in the males and serrate in the females. The life-history of _Metoecus_ has been studied by T. A. Chapman, who finds that the eggs are laid in old wood, and that the triungulin seeks to attach itself to a social wasp, who carries it to her nest. There it feeds first as an internal parasite of the wasp-grub, then bores its way out, moults and devours the wasp larva from outside. The wasps are said to leave the larval or pupal _Metoecus_ unmolested, but they are hostile to the developed beetles, which hasten to leave the nest as soon as possible.

STREPSIPTERA.--Much difference of opinion has prevailed with regard to the curious, tiny, parasitic insects included in this division, some authorities considering that they should be referred to a distinct order, while others would group them in the family _Meloidae_ just described. While from the nature of their life-history there is no doubt that they have a rather close relationship to the _Meloidae_, their structure is so remarkable that it seems advisable to regard them as at least a distinct tribe of Coleoptera.

They may be comprised in a single family, the _Stylopidae_. The males are very small, free-flying insects with the prothorax, mesothorax and elytra greatly reduced, the latter appearing as little, twisted strips, while the metathorax is relatively large, with its wings broad and capable of longitudinal folding. The feelers are branched and the jaws vestigial. The female is a segmented, worm-like creature, spending her whole life within the body of the bee, wasp or bug on which she is parasitic. One end of her body protrudes from between two of the abdominal segments of the host; it has been a subject of dispute whether this protruded end is the head or the tail, but there can be little doubt that it is the latter. While thus carried about by the host-insect, the female is fertilized by the free-flying male, and gives birth to a number of tiny triungulin larvae. The chief points in the life-history of _Stylops_ and _Xenos_, which are parasitic on certain bees (_Andrena_) and wasps (_Polistes_), have been investigated by K. T. E. von Siebold (1843) and N. Nassonov (1892). The little triungulins escape on to the body of the bee or wasp; then those that are to survive must leave their host for a non-parasitized insect. Clinging to her hairs they are carried to the nest, where they bore into the body of a bee or wasp larva, and after a moult become soft-skinned legless maggots. The growth of the parasitic larva does not stop the development of the host-larva, and when the latter pupates and assumes the winged form, the stylopid, which has completed its transformation, is carried to the outer world. The presence of a _Stylops_ causes derangement in the body of its host, and can be recognized by various external signs. Other genera of the family are parasitic on Hemiptera--bugs and frog-hoppers--but nothing is known as to the details of their life-history.

LAMELLICORNIA.--This is a very well-marked tribe of beetles, characterized by the peculiar elongation and flattening of three or more of the terminal antennal segments, so that the feeler seems to end in a number of leaf-like plates, or small comb-teeth (fig. 26, b, c). The wings are well developed for flight, and there is a tendency in the group, especially among the males, towards an excessive development of the mandibles or the presence of enormous, horn-like processes on the head or pronotum. There are four malpighian tubes. The larvae are furnished with large heads, powerful mandibles and well-developed legs, but the body-segments are feebly chitinized, and the tail-end is swollen. They feed in wood or spend an underground life devouring roots or animal excrement.

The _Lucanidae_ or stag beetles (figs. 1 and 25) have the terminal antennal segments pectinate, and so arranged that the comb-like part of the feeler cannot be curled up, while the elytra completely cover the abdomen. There are about 600 species in the family, the males being usually larger than the females, and remarkable for the size of their mandibles. In the same species, however, great variation occurs in the development of the mandibles, and the breadth of the head varies correspondingly, the smallest type of male being but little different in appearance from the female. The larvae of _Lucanidae_ live within the wood of trees, and may take three or four years to attain their full growth. The _Passalidae_ are a tropical family of beetles generally considered to be intermediate between stag-beetles and chafers, the enlarged segments of the feeler being capable of close approximation.

The _Scarabaeidae_ or chafers are an enormous family of about 15,000 species. The plate-like segments of the feeler (fig. 26, b, c) can be brought close together so as to form a club-like termination; usually the hinder abdominal segments are not covered by the elytra. In this family there is often a marked divergence between the sexes; the terminal antennal segments are larger in the male than in the female, and the males may carry large spinous processes on the head or prothorax, or both. These structures were believed by C. Darwin to be explicable by sexual selection. The larvae have the three pairs of legs well developed, and the hinder abdominal segments swollen. Most of the _Scarabaeidae_ are vegetable-feeders, but one section of the family--represented in temperate countries by the dor-beetles (_Geotrupes_) (fig. 28) and _Aphodius_, and in warmer regions by the "sacred" beetles of the Egyptians (_Scarabaeus_) (fig. 27), and allied genera--feed both in the adult and larval stages, on dung or decaying animal matter. The heavy grubs of _Geotrupes_, their swollen tail-ends black with the contained food-material, are often dug up in numbers in well-manured fields. The habits of _Scarabaeus_ have been described in detail by J. H. Fabre. The female beetle in spring-time collects dung, which she forms into a ball by continuous rolling, sometimes assisted by a companion. This ball is buried in a suitable place, and serves the insect as a store of food. During summer the insects rest in their underground retreats, then in autumn they reappear to bury another supply of dung, which serves as food for the larvae. Fabre states that the mother-insect carefully arranges the food-supply so that the most nutritious and easily digested portion is nearest the egg, to form the first meal of the young larva. In some species of _Copris_ it is stated that the female lays only two or three eggs at a time, watching the offspring grow to maturity, and then rearing another brood.

Among the vegetable-feeding chafers we usually find that while the perfect insect devours leaves, the larva lives underground and feeds on roots. Such are the habits of the cockchafer (_Melolontha vulgaris_) and other species that often cause great injury to farm and garden crops (see CHAFER). Many of these insects, such as the species of _Phanaeus_ (fig. 29) and _Cetonia_ (fig. 30), are adorned with metallic or other brilliant colours. The African "goliath-beetles" (fig. 31) and the American "elephant-beetles" (_Dynastes_) are the largest of all insects.

ANCHISTOPODA.--The families of beetles included by Kolbe in this group are distinguished by the possession of six malpighian tubes, and a great reduction in one or two of the tarsal segments, so that there seem to be only four or three segments in each foot; hence the names _Tetramera_ and _Trimera_ formerly applied to them. The larvae have soft-skinned bodies sometimes protected by rows of spiny tubercles, the legs being fairly developed in some families and greatly reduced or absent in others. As might be expected, degeneration in larval structure is correlated with a concealed habit of life.

The _Coccinellidae_, or ladybirds (fig. 32), are a large family of beetles, well known by their rounded convex bodies, usually shining and hairless. They have eleven segments to the feeler, which is clubbed at the tip, and apparently three segments only in each foot. Ladybirds are often brightly marked with spots and dashes, their coloration being commonly regarded as an advertisement of inedibility. The larvae have a somewhat swollen abdomen, which is protected by bristle-bearing tubercles. Like the perfect insects, they are predaceous, feeding on plant-lice (_Aphidae_) and scale insects (_Coccidae_). Their role in nature is therefore beneficial to the cultivator. The _Endomychidae_ (fig. 33), an allied family, are mostly fungus-eaters. In the _Erotylidae_ and a few other small related families the feet are evidently four-segmented.

The _Chrysomelidae_, or leaf-beetles (figs. 34, 35), are a very large family, with "tetramerous" tarsi; there seem to be only four segments to the foot, but there are really five, the fourth being greatly reduced. The mandibles are strong, adapted for biting the vegetable substances on which these beetles feed, and the palps of the second maxillae have three segments. Most of the _Chrysomelidae_ are metallic in colour and convex in form; in some the head is concealed beneath the prothorax, and the so-called "tortoise" beetles (_Cassidinae_) have the elytra raised into a prominent median ridge. The most active form of larva found in this family resembles in shape that of a ladybird, tapering towards the tail end, and having the trunk segments protected by small firm sclerites. Such larvae, and also many with soft cuticle and swollen abdomen--those of the notorious "Colorado beetle," for example--feed openly on foliage. Others, with soft, white, cylindrical bodies, which recall the caterpillars of moths, burrow in the leaves or stems of plants. The larvae of the tortoise-beetles have the curious habit of forming an umbrella-like shield out of their own excrement, held in position by the upturned tail-process. The larvae of the beautiful, elongate, metallic _Donaciae_ live in the roots and stems of aquatic plants, obtaining thence both food and air. The larva pierces the vessels of the plant with sharp processes at the hinder end of its body. In this way it is believed that the sub-aqueous cocoon in which the pupal stage is passed becomes filled with air.

The _Cerambycidae_, or longhorn beetles, are recognizable by their slender, elongate feelers, which are never clubbed and rarely serrate. The foot has apparently four segments, as in the _Chrysomelidae_. The beetles are usually elongate and elegant in form, often adorned with bright bands of colour, and some of the tropical species attain a very large size (figs. 36, 37). The feelers are usually longer in the male than in the female, exceeding in some cases by many times the length of the body. The larvae have soft, fleshy bodies, with the head and prothorax large and broad, and the legs very much reduced. They live and feed in the wood of trees. Consequently, beetles of this family are most abundant in forest regions, and reach their highest development in the dense virgin forests of tropical countries, South America being particularly rich in peculiar genera.

The _Bruchidae_, or seed-beetles, agree with the two preceding families in tarsal structure; the head is largely hidden by the pronotum, and the elytra are short enough to leave the end of the abdomen exposed (fig. 38). The development of the pea and bean-beetles has been carefully studied by C. V. Riley, who finds that the young larva, hatched from the egg laid on the pod, has three pairs of legs, and that these are lost after the moult that occurs when the grub has bored its way into the seed. In Great Britain the beetle, after completing its development, winters in the seed, waiting to emerge and lay its eggs on the blossom in the ensuing spring.

RHYNCHOPHORA.--The _Rhynchophora_ are a group of beetles easily recognized by the elongation of the head into a beak or snout, which carries the feelers at its sides and the jaws at its tip. The third tarsal segment is broad and bi-lobed, and the fourth is so small that the feet seem to be only four-segmented. There are six malpighian tubes. The ventral sclerite of the head-skeleton (gula), well developed in most families of beetles, is absent among the _Rhynchophora_, while the palps of the maxillae are much reduced. The larvae have soft, white bodies and, with very few exceptions, no legs.

Of the four families included in this group, the _Anthribidae_ (fig. 39) have jointed, flexible palps, feelers--often of excessive length--with a short basal segment, and the three terminal segments forming a club, and, in some genera, larvae with legs. There are nearly 1000 known species, most of which live in tropical countries. The _Brenthidae_ are a remarkable family almost confined to the tropics; they are elongate and narrow in form (fig. 40), with a straight, cylindrical snout which in some male beetles of the family is longer than the rest of the body.

The _Curculionidae_, or weevils (q.v.), comprising 23,000 species, are by far the largest family of the group. The maxillary palps are short and rigid, and there is no distinct labrum, while the feelers are usually of an "elbowed" form, the basal segment being very elongate (figs. 41, 42). They are vegetable feeders, both in the perfect and larval stages, and are often highly injurious. The female uses her snout as a boring instrument to prepare a suitable place for egg-laying. The larvae (fig. 3) of some weevils live in seeds; others devour roots, while the parent-beetles eat leaves; others, again, are found in wood or under bark. The _Scolytidae_, or bark-beetles, are a family of some 1500 species, closely allied to the _Curculionidae_, differing only in the feeble development of the snout. They have clubbed feelers, and their cylindrical bodies (fig. 43) are well adapted for their burrowing habits under the bark of trees. Usually the mother-beetle makes a fairly straight tunnel along which, at short intervals, she lays her eggs. The grubs, when hatched, start galleries nearly at right angles to this, and when fully grown form oval cells in which they pupate; from these the young beetles emerge by making circular holes directly outward through the bark.

COLEPEPER, JOHN COLEPEPER (or CULPEPPER), 1ST BARON (d. 1660), English politician, was the only son of Sir John Colepeper of Wigsell, Sussex. He began his career in military service abroad, and came first into public notice at home through his knowledge of country affairs, being summoned often before the council board to give evidence on such matters. He was knighted, and was elected member for Kent in the Long Parliament, when he took the popular side, speaking against monopolies on the 9th of November 1640, being entrusted with the impeachment of Sir Robert Berkeley on the 12th of February 1641, supporting Stafford's attainder, and being appointed to the committee of defence on the 12th of August 1641. He separated, however, from the popular party on the Church question, owing to political rather than religious objections, fearing the effect of the revolutionary changes which were now contemplated. He opposed the London petition for the abolition of episcopacy, the project of religious union with the Scots, and the Root and Branch Bill, and on the 1st of September he moved a resolution in defence of the prayer-book. In the following session he opposed the militia bill and the Grand Remonstrance, and finally on the 2nd of January 1642 he joined the king's party, taking office as chancellor of the exchequer. He highly disapproved of the attempt upon the five members, which was made without his knowledge, but advised the enterprise against Hull. On the 25th of August 1642 he appeared at the bar of the House of Commons to deliver the king's final proposals for peace, and was afterwards present at Edgehill, where he took part in Prince Rupert's charge and opposed the retreat of the king's forces from the battlefield. In December he was made by Charles master of the rolls. He was a leading member of the Oxford Parliament, and was said, in opposition to the general opinion, to have counselled considerable concessions to secure peace. His influence in military affairs caused him to be much disliked by Prince Rupert and the army, and the general animosity against him was increased by his advancement to the peerage on the 21st of October 1644 by the title of Baron Colepeper of Thoresway in Lincolnshire.

He was despatched with Hyde in charge of the prince of Wales to the West in March 1645, and on the 2nd of March 1646, after Charles's final defeat, embarked with the prince for Scilly, and thence to France. He strongly advocated the gaining over of the Scots by religious concessions, a policy supported by the queen and Mazarin, but opposed by Hyde and other leading royalists, and constantly urged this course upon the king, at the same time deprecating any yielding on the subject of the militia. He promoted the mission of Sir John Berkeley in 1647 to secure an understanding between Charles and the army. In 1648 he accompanied the prince in his unsuccessful naval expedition, and returned with him to the Hague, where violent altercations broke out among the royalist leaders, Colepeper going so far, on one occasion in the council, as to challenge Prince Rupert, and being himself severely assaulted in the streets by Sir Robert Walsh. He continued after the execution of the king to press the acceptance on Charles II. of the Scottish proposals. He was sent to Russia in 1650, where he obtained a loan of 20,000 roubles from the tsar, and, soon after his return, to Holland, to procure military assistance. By the treaty, agreed to between Cromwell and Mazarin, of August 1654, Colepeper was obliged to leave France, and he appears henceforth to have resided in Flanders. He accompanied Charles II. to the south of France in September 1659, at the time of the treaty of the Pyrenees. At the Restoration he returned to England, but only survived a few weeks, dying on the 11th of June 1660.

Several contemporary writers agree in testifying to Colepeper's great debating powers and to his resources as an adviser, but complain of his want of stability and of his uncertain temper. Clarendon, with whom he was often on ill terms, speaks generally in his praise, and repels the charge of corruption levelled against him. That he was gifted with considerable political foresight is shown by a remarkable letter written on the 20th of September 1658 on the death of Cromwell, in which he foretells with uncommon sagacity the future developments in the political situation, advises the royalists to remain inactive till the right moment and profit by the division of their opponents, and distinguishes Monck as the one person willing and capable of effecting the Restoration (_Clarendon State Papers_, iii. 412). Colepeper was twice married, (1) to Philippa, daughter of Sir John Snelling, by whom he had one son, who died young, and a daughter, and (2) to Judith, daughter of Sir J. Colepeper of Hollingbourn, Kent, by whom he had seven children. Of these Thomas (d. 1719; governor of Virginia 1680-1683) was the successor in the title, which became extinct on the death of his younger brother Cheney in 1725. (P. C. Y.)

COLERAINE, a seaport and market town of Co. Londonderry, Ireland, in the north parliamentary division, on the Bann, 4 m. from its mouth, and 61½ m. N.W. by N. from Dublin by the Northern Counties (Midland) railway. Pop. of urban district (1901) 6958. The town stands upon both sides of the river, which is crossed by a handsome stone bridge, connecting the town and its suburb, Waterside or Killowen. The principal part is on the east bank, and consists of a central square called the Diamond, and several diverging streets. Among institutions may be mentioned the public schools founded in 1613 and maintained by the Honourable Irish Society, and the Academical Institution, maintained by the Irish Society and the London Clothworkers' Company. The linen trade has long been extensively carried on in the town, from which, indeed, a fine description of cloth is known as "Coleraines." Whisky-distilling, pork-curing, and the salmon and eel fisheries are prosecuted. The mouth of the river was formerly obstructed by a bar, but piers were constructed, and the harbours greatly improved by grants from the Irish Society of London and from a loan under the River Bann Navigation Act 1879. Coleraine ceased to return one member to the Imperial parliament in 1885; having previously returned two to the Irish parliament until the Union. It was incorporated by James I. It owed its importance mainly to the Irish Society, which was incorporated as the Company for the New Plantation of Ulster in 1613. Though fortified only by an earthen wall, it managed to hold out against the rebels in 1641. There are no remains of a former priory, monastery and castle. A rath or encampment of large size occupies Mount Sandel, 1 m. south-east.

COLERIDGE, HARTLEY (1796-1849), English man of letters, eldest son of the poet Samuel Taylor Coleridge, was born on the 19th of September 1796, near Bristol. His early years were passed under Southey's care at Greta Hall, Keswick, and he was educated by the Rev. John Dawes at Ambleside. In 1815 he went to Oxford, as scholar of Merton College. His university career, however, was very unfortunate. He had inherited the weakness of purpose, as well as the splendid conversational powers, of his father, and lapsed into habits of intemperance. He was successful in gaining an Oriel fellowship, but at the close of the probationary year (1820) was judged to have forfeited it. The authorities could not be prevailed upon to reverse their decision; but they awarded to him a free gift of £300. Hartley Coleridge then spent two years in London, where he wrote short poems for the _London Magazine_. His next step was to become a partner in a school at Ambleside, but this scheme failed. In 1830 a Leeds publisher, Mr. F. E. Bingley, made a contract with him to write biographies of Yorkshire and Lancashire worthies. These were afterwards republished under the title of _Biographia Borealis_ (1833) and _Worthies of Yorkshire and Lancashire_ (1836). Bingley also printed a volume of his poems in 1833, and Coleridge lived in his house until the contract came to an end through the bankruptcy of the publisher. From this time, except for two short periods in 1837 and 1838 when he acted as master at Sedbergh grammar school, he lived quietly at Grasmere and (1840-1849) Rydal, spending his time in study and wanderings about the countryside. His figure was as familiar as Wordsworth's, and his gentleness and simplicity of manner won for him the friendship of the country-people. In 1839 appeared his edition of Massinger and Ford, with biographies of both dramatists. The closing decade of Coleridge's life was wasted in what he himself calls "the woeful impotence of weak resolve." He died on the 6th of January 1849. The prose style of Hartley Coleridge is marked by much finish and vivacity; but his literary reputation must chiefly rest on the sanity of his criticisms, and above all on his _Prometheus_, an unfinished lyric drama, and on his sonnets. As a sonneteer he achieved real excellence, the form being exactly suited to his sensitive genius. _Essays and Marginalia_, and _Poems_, with a memoir by his brother Derwent, appeared in 1851.

COLERIDGE, JOHN DUKE COLERIDGE, 1ST BARON (1820-1894), lord chief justice of England, was the eldest son of Sir John Taylor Coleridge. He was born at Heath's Court, Ottery St Mary, on the 3rd of December 1820. He was educated at Eton and Balliol College, Oxford, of which he was a scholar. He was called to the bar in 1846, and went the western circuit, rising steadily, through more than twenty years of hard work, till in 1865 he was returned as member for Exeter in the Liberal interest. The impression which he made on the heads of his party was so favourable that they determined, early in the session of 1867, to put him forward as the protagonist of their attack on the Conservative government. But that move seemed to many of their staunchest adherents unwise, and it was frustrated by the active opposition of a section, including Hastings Russell (later ninth duke of Bedford), his brother Arthur, member for Tavistock, Alexander Mitchell of Stow, A. W. Kinglake and Henry Seymour. They met to deliberate in the tea-room of the House, and were afterwards sometimes confounded with the tea-room party which was of subsequent formation and under the guidance of a different group. The protest was sufficient to prevent the contemplated attack being made, but the Liberals returned to power in good time with a large majority behind them in 1868. Coleridge was made, first solicitor-, and then attorney-general.

As early as 1863 a small body of Oxford men in parliament had opened fire against the legislation which kept their university bound by ecclesiastical swaddling clothes. They had made a good deal of progress in converting the House of Commons to their views before the general election of 1865. That election having brought Coleridge into parliament, he was hailed as a most valuable ally, whose great university distinction, brilliant success as an orator at the bar, and hereditary connexion with the High Church party, entitled him to take the lead in a movement which, although gathering strength, was yet very far from having achieved complete success. The clerically-minded section of the Conservative party could not but listen to the son of Sir John Coleridge, the godson of Keble, and the grand-nephew of the man who had been an indirect cause of the Anglican revival of 1833,--for John Stuart Mill was right when he said that the poet Coleridge and the philosopher Bentham were, so far as England was concerned, the leaders of the two chief movements of their times: "it was they who taught the teachers, and who were the two great seminal minds."

Walking up one evening from the House of Commons to dine at the Athenaeum with Henry Bruce (afterwards Lord Aberdare) and another friend, Coleridge said: "There is a trial coming on which will be one of the most remarkable _causes célèbres_ that has ever been heard of." This was the Tichborne case, which led to proceedings in the criminal courts rising almost to the dignity of a political event. The Tichborne trial was the most conspicuous feature of Coleridge's later years at the bar, and tasked his powers as an advocate to the uttermost, though he was assisted by the splendid abilities and industry of Charles (afterwards Lord) Bowen. In November 1873 Coleridge succeeded Sir W. Bovill as chief justice of the common pleas, and was immediately afterwards raised to the peerage as Baron Coleridge of Ottery St Mary. In 1880 he was made lord chief justice of England on the death of Sir Alexander Cockburn.

In jury cases his quickness in apprehending facts and his lucidity in arranging them were very remarkable indeed. He was not one of the most learned of lawyers, but he was a great deal more learned than many people believed him to be, and as an ecclesiastical lawyer had perhaps few or no superiors. His fault--a natural fault in one who had been so successful as an advocate--was that of being too apt to take one side. He allowed, also, certain political or personal prepossessions to colour the tone of his remarks from the bench. A game-preserving landlord had not to thank the gods when his case, however buttressed by generally accepted claims, came before Coleridge. Towards the end of his life his health failed, and he became somewhat indolent. On the whole, he was not so strong a man in his judicial capacity as Campbell or Cockburn; but it must be admitted that his scholarship, his refinement, his power of oratory, and his character raised the tone of the bench while he sat upon it, and that if it has been adorned by greater judicial abilities, it has hardly ever known a greater combination of varied merits. It is curious to observe that of all judges the man whom he put highest was one very unlike himself, the great master of the rolls, Sir William Grant. Coleridge died in harness on the 14th of June 1894.

Coleridge's work, first as a barrister, and then as a judge, prevented his publishing as much as he otherwise would have done, but his addresses and papers would, if collected, fill a substantial volume and do much honour to his memory. One of the best, and one most eminently characteristic of the man, was his inaugural address to the Philosophical Institution at Edinburgh in 1870; another was a paper on Wordsworth (1873). He was an exceptionally good letter-writer. Of travel he had very little experience. He had hardly been to Paris; once, quite near the end of his career, he spent a few days in Holland, and came back a willing slave to the genius of Rembrandt; but his longest absence from England was a visit, which had something of a representative legal character, to the United States. It is strange that a man so steeped in Greek and Roman poetry, so deeply interested in the past, present and future of Christianity, never saw Rome, or Athens, or the Holy Land. A subsidiary cause, no doubt, was the fatal custom of neglecting modern languages at English schools. He felt himself at a disadvantage when he passed beyond English-speaking lands, and cordially disliked the situation. No notice of Coleridge should omit to make mention of his extraordinary store of anecdotes, which were nearly always connected with Eton, Oxford, the bar or the bench. His exquisite voice, considerable power of mimicry, and perfect method of narration added greatly to the charm. He once told, at the table of Dr Jowett, master of Balliol, anecdotes through the whole of dinner on Saturday evening, through the whole of breakfast, lunch and dinner the next day, through the whole journey on Monday morning from Oxford to Paddington, without ever once repeating himself. He was frequently to be seen at the Athenaeum, was a member both of Grillion's and The Club, as well as of the Literary Society, of which he was president, and whose meetings he very rarely missed. Bishop Copleston is said to have divided the human race into three classes,--men, women and Coleridges. If he did so, he meant, no doubt, to imply that the family of whom the poet of _Christabel_ was the chief example regarded themselves as a class to themselves, the objects of a special dispensation. John Duke Coleridge was sarcastic and critical, and at times over-sensitive. But his strongest characteristics were love of liberty and justice. By birth and connexions a Conservative, he was a Liberal by conviction, and loyal to his party and its great leader, Mr Gladstone.

Coleridge had three sons and a daughter by his first wife, Jane Fortescue, daughter of the Rev. George Seymour of Freshwater. She was an artist of real genius, and her portrait of Cardinal Newman was considered much better than the one by Millais. She died in February 1878; a short notice of her by Dean Church of St Paul's was published in the _Guardian_, and was reprinted in her husband's privately printed collection of poems. Coleridge remained for some years a widower, but married in 1885 Amy Augusta Jackson Lawford, who survived him. He was succeeded in the peerage by his eldest son, Bernard John Seymour (b. 1851), who went to the bar and became a K.C. in 1892. In 1907 he was appointed a judge of the Supreme Court. The two other sons were Stephen (b. 1854), a barrister, secretary to the Anti-Vivisection Society, and Gilbert James Duke (b. 1859).

His _Life and Correspondence_, edited by E. H. Coleridge, was published in 1904; see further E. Manson, _Builders of our Law_ (1904); and for the history of the Coleridge family see Lord Coleridge, _The Story of a Devonshire House_ (1907). (M. G. D.)

COLERIDGE, SIR JOHN TAYLOR (1790-1876), English judge, the second son of Captain James Coleridge and nephew of the poet S. T. Coleridge, was born at Tiverton, Devon, and was educated at Corpus Christi College, Oxford, where he had a brilliant career. He graduated in 1812 and was soon after made a fellow of Exeter; in 1819 he was called to the bar at the Middle Temple and practised for some years on the western circuit. In 1824, on Gifford's retirement, he assumed the editorship of the _Quarterly Review_, resigning it a year afterwards in favour of Lockhart. In 1825 he published his excellent edition of _Blackstone's Commentaries_, and in 1832 he was made a serjeant-at-law and recorder of Exeter. In 1835 he was appointed one of the judges of the king's bench. In 1852 his university created him a D.C.L., and in 1858 he resigned his judgeship, and was made a member of the privy council. In 1869, although in extreme old age, he produced his pleasant _Memoir of the Rev. John Keble_, whose friend he had been since their college days, a third edition of which was issued within a year. He died on the 11th of February 1876 at Ottery St Mary, Devon, leaving two sons and a daughter; the eldest son, John Duke, 1st Baron Coleridge (q.v.), became lord chief justice of England; the second son, Henry James (1822-1893), left the Anglican for the Roman Catholic church in 1852, and became well-known as a Jesuit divine, editor of _The Month_, and author of numerous theological works. Sir John Taylor Coleridge's brothers, James Duke and Henry Nelson (husband of Sara Coleridge), are referred to in other articles; his brother Francis George was the father of Arthur Duke Coleridge (b. 1830), clerk of assizes on the midland circuit and author of _Eton in the Forties_, whose daughter Mary E. Coleridge (1861-1907) became a well-known writer of fiction.

COLERIDGE, SAMUEL TAYLOR (1772-1834), English poet and philosopher, was born on the 21st of October 1772, at his father's vicarage of Ottery St Mary's, Devonshire. His father, the Rev. John Coleridge (1719-1781), was a man of some mark. He was known for his great scholarship, simplicity of character, and affectionate interest in the pupils of the grammar school, of which he was appointed master a few months before becoming vicar of the parish (1760), reigning in both capacities till his death. He had married twice. The poet was the youngest child of his second wife, Anne Bowdon (d. 1809), a woman of great good sense, and anxiously ambitious for the success of her sons. On the death of his father, a presentation to Christ's Hospital was procured for Coleridge by the judge, Sir Francis Buller, an old pupil of his father's. He had already begun to give evidence of a powerful imagination, and he has described in a letter to his valued friend, Tom Poole, the pernicious effect which the admiration of an uncle and his circle of friends had upon him at this period. For eight years he continued at Christ's Hospital. Of these school-days Charles Lamb has given delightful glimpses in the _Essays of Elia_. The headmaster, Bowyer (as he was called, though his name was Boyer), was a severe disciplinarian, but respected by his pupils. Middleton, afterwards known as a Greek scholar, and bishop of Calcutta, reported Coleridge to Bowyer as a boy who read Virgil for amusement, and from that time Bowyer began to notice him and encouraged his reading. Some compositions in English poetry, written at sixteen, and not without a touch of genius, give evidence of the influence which Bowles, whose poems were then in vogue, had over his mind at this time. Before he left school his constitutional delicacy of frame, increased by swimming the New River in his clothes, began to give him serious discomfort.

In February 1791 he was entered at Jesus College, Cambridge. A school-fellow who followed him to the university has described in glowing terms evenings in his rooms, "when Aeschylus, and Plato, and Thucydides were pushed aside, with a pile of lexicons and the like, to discuss the pamphlets of the day. Ever and anon a pamphlet issued from the pen of Burke. There was no need of having the book before us;--Coleridge had read it in the morning, and in the evening he would repeat whole pages verbatim." William Frend, a fellow of Jesus, accused of sedition and Unitarianism, was at this time tried and expelled from Cambridge. Coleridge had imbibed his sentiments, and joined the ranks of his partisans. He grew discontented with university life, and in 1793, pressed by debt, went to London. Perhaps he was also influenced by his passion for Mary Evans, the sister of one of his school-fellows. A poem in the _Morning Chronicle_ brought him a guinea, and when that was spent he enlisted in the 15th Dragoons under the name of Silas Tomkyn Comberbache. One of the officers of the dragoon regiment, finding a Latin sentence inscribed on a wall, discovered the condition of the very awkward recruit. Shortly afterwards an old school-fellow (G. L. Tuckett) heard of his whereabouts, and by the intervention of his brother, Captain James Coleridge, his discharge was procured. He returned for a short time to Cambridge, but quitted the university without a degree in 1794. In the same year he visited Oxford, and after a short tour in Wales went to Bristol, where he met Southey. The French Revolution had stirred the mind of Southey to its depths. Coleridge received with rapture his new friend's scheme of Pantisocracy. On the banks of the Susquehanna was to be founded a brotherly community, where selfishness was to be extinguished, and the virtues were to reign supreme. No funds were forthcoming, and in 1795, to the chagrin of Coleridge, the scheme was dropped. In 1794 _The Fall of Robespierre_, of which Coleridge wrote the first act and Southey the other two, appeared. At Bristol Coleridge formed the acquaintance of Joseph Cottle, the bookseller, who offered him thirty guineas for a volume of poems. In October of 1795 Coleridge married Sarah Fricker, and took up his residence at Clevedon on the Bristol Channel. A few weeks afterwards Southey married a sister of Mrs Coleridge, and on the same day quitted England for Portugal.

Coleridge began to lecture in Bristol on politics and religion. He embodied the first two lectures in his first prose publication, _Conciones ad Populum_ (1795). The book contained much invective against Pitt, and in after life Coleridge declared that, with this exception, and a few pages involving philosophical tenets which he afterwards rejected, there was little or nothing he desired to retract. The first volume of _Poems_ was published by Cottle early in 1796. Coleridge projected a periodical called _The Watchman_, and in 1796 undertook a journey, well described in the _Biographic Literaria_, to enlist subscribers. _The Watchman_ had a brief life of two months, but at this time Coleridge began to think of becoming a Unitarian preacher, and abandoning literature for ever. Hazlitt has recorded his very favourable impression of a remarkable sermon delivered at Shrewsbury; but there are other accounts of Coleridge's preaching not so enthusiastic. In the summer of 1795 he met for the first time the brother poet with whose name his own will be for ever associated. Wordsworth and his sister had established themselves at Racedown in the Dorsetshire hills, and here Coleridge visited them in 1797. There are few things in literary history more remarkable than this friendship. The gifted Dorothy Wordsworth described Coleridge as "thin and pale, the lower part of the face not good, wide mouth, thick lips, not very good teeth, longish, loose, half-curling, rough, black hair,"--but all was forgotten in the magic charm of his utterance. Wordsworth, who declared, "The only wonderful man I ever knew was Coleridge," seems at once to have desired to see more of his new friend. He and his sister removed in July 1797 to Alfoxden, near Nether Stowey, to be in Coleridge's neighbourhood, and in the most delightful and unrestrained intercourse the friends spent many happy days. It was the delight of each one to communicate to the other the productions of his mind, and the creative faculty of both poets was now at its best. One evening, at Watchett on the British Channel, _The Ancient Mariner_ first took shape. Coleridge was anxious to embody a dream of a friend, and the suggestion of the shooting of the albatross came from Wordsworth, who gained the idea from Shelvocke's _Voyage_ (1726). A joint volume was planned. Wordsworth was to show the real poetry that lies hidden in commonplace subjects, while Coleridge was to treat supernatural subjects to illustrate the common emotions of humanity. From this sprang the _Lyrical Ballads_, to which Coleridge contributed _The Ancient Mariner_, the _Nightingale_ and two scenes from _Osorio_, and after much cogitation the book was published in 1798 at Bristol by Cottle, to whose reminiscences, often indulging too much in detail, we owe the account of this remarkable time. A second edition of the _Lyrical Ballads_ in 1800 included another poem by Coleridge--_Love_, to which subsequently the sub-title was given of _An Introduction to the Tale of the Dark Ladie_. To the Stowey period belong also the tragedy of _Osorio_ (afterwards known as _Remorse_), _Kubla Khan_ and the first part of _Christabel_. In 1798 an annuity, granted him by the brothers Wedgwood, led Coleridge to abandon his reluctantly formed intention of becoming a Unitarian minister. For many years he had desired to see the continent, and in September 1798, in company with Wordsworth and his sister, he left England for Hamburg. _Satyrane's Letters_ (republished in _Biog. Lit._ 1817) give an account of the tour.

A new period in Coleridge's life now began. He soon left the Wordsworths to spend four months at Ratzeburg, whence he removed to Göttingen to attend lectures. A great intellectual movement had begun in Germany. Coleridge was soon in the full whirl of excitement. He learnt much from Blumenbach and Eichhorn, and took interest in all that was going on around him. During his stay of nine months in Germany, he made himself master of the language to such purpose that the translation of _Wallenstein_--his first piece of literary work after his return to England--was actually accomplished in six weeks. It was published in 1800, and, although it failed to make any impression on the general public, it became at once prized by Scott and others as it deserved. It is matter for regret that a request to Coleridge that he should undertake to translate _Faust_ never received serious attention from him. During these years Coleridge wrote many newspaper articles and some poems, among them "Fire, Famine and Slaughter," for the _Morning Post_ (January 8, 1798). He had vehemently opposed Pitt's policy, but a change came over his way of thought, and he found himself separated from Fox on the question of a struggle with Napoleon. He had lost his admiration for the Revolutionists, as his "Ode to France" shows (_Morning Post_, April 16, 1798). Like many other Whigs, he felt that all questions of domestic policy must at a time of European peril be postponed. From this time, however, his value for the ordered liberty of constitutional government increased; and though never exactly to be found among the ranks of old-fashioned Constitutionalists, during the remainder of his life he kept steadily in view the principles which received their full exposition in his well-known work on _Church and State_. In the year 1800 Coleridge left London for the Lakes. Here in that year he wrote the second part of _Christabel_. In 1803 Southey became a joint lodger with Coleridge at Greta Hall, Keswick, of which in 1812 Southey became sole tenant and occupier.

In 1801 begins the period of Coleridge's life during which, in spite of the evidence of work shown in his compositions, he sank more and more under the dominion of opium, in which he may have first indulged at Cambridge. Few things are so sad to read as the letters in which he details the consequences of his transgression. He was occasionally seen in London during the first years of the century, and wherever he appeared he was the delight of admiring circles. He toured in Scotland with the Wordsworths in 1803, visited Malta in 1804, when for ten months he acted as secretary to the governor, and stayed nearly eight months at Naples and Rome in 1805-1806. In Rome he received a hint that his articles in the _Morning Post_ had been brought to Napoleon's notice, and he made the voyage from Leghorn in an American ship. On a visit to Somersetshire in 1807 he met De Quincey for the first time, and the younger man's admiration was shown by a gift of £300, "from an unknown friend." In 1809 he started a magazine called _The Friend_, which continued only for eight months. At the same time Coleridge began to contribute to the _Courier_. In 1808 he lectured at the Royal Institution, but with little success, and two years later he gave his lectures on Shakespeare and other poets. These lectures attracted great attention and were followed by two other series. In 1812 his income from the Wedgwoods was reduced, and he settled the remainder on his wife. His friends were generous in assisting him with money. Eventually Mackintosh obtained a grant of £100 a year for him in 1824 during the lifetime of George IV., as one of the royal associates of the Society of Literature, and at different times he received help principally from Stuart, the publisher, Poole, Sotheby, Sir George Beaumont, Byron and Wordsworth, while his children shared Southey's home at Keswick. But between 1812 and 1817 Coleridge made a good deal by his work, and was able to send money to his wife in addition to the annuity she received. The tragedy of _Remorse_ was produced at Drury Lane in 1813, and met with considerable success. Three years after this, having failed to conquer the opium habit, he determined to enter the family of Mr James Gillman, who lived at Highgate. The letter in which he discloses his misery to this kind and thoughtful man gives a real insight into his character. Under judicious treatment the hour of mastery at last arrived. The shore was reached, but the vessel had been miserably shattered in its passage through the rocks. For the rest of his life he hardly ever left his home at Highgate. During his residence there, _Christabel_, written many years before, and known to a favoured few, was first published in a volume with _Kubla Khan_ and the _Pains of Sleep_ in 1816. He read widely and wisely, in poetry, philosophy and divinity. In 1816 and the following year, he gave his _Lay Sermons_ to the world. _Sibylline Leaves_ appeared in 1817; the _Biographia Literaria_ and a revised edition of _The Friend_ soon followed. Seven years afterwards his most popular prose work--_The Aids to Reflection_--first appeared. His last publication, in 1830, was the work on _Church and State_. It was not till 1840 that his _Confessions of an Inquiring Spirit_, by far his most seminal work, was posthumously published. In 1833 he appeared at the meeting of the British Association at Cambridge, but he died in the following year (25th of July 1834), and was buried in the churchyard close to the house of Mr Gillman, where he had enjoyed every consolation which friendship and love could render. Coleridge died in the communion of the Church of England, of whose polity and teaching he had been for many years a loving admirer. An interesting letter to his god-child, written twelve days before his death, sums up his spiritual experience in a most touching form.

Of the extraordinary influence which he exercised in conversation it is impossible to speak fully here. Many of the most remarkable among the younger men of that period resorted to Highgate as to the shrine of an oracle, and although one or two disparaging judgments, such as that of Carlyle, have been recorded, there can be no doubt that since Samuel Johnson there had been no such power in England. His nephew, Henry Nelson Coleridge, gathered together some specimens of the _Table Talk_ of the few last years. But remarkable as these are for the breadth of sympathy and extent of reading disclosed, they will hardly convey the impressions furnished in a dramatic form, as in Boswell's great work. Four volumes of _Literary Remains_ were published after his death, and these, along with the chapters on the poetry of Wordsworth in the _Biographia Literaria_, may be said to exhibit the full range of Coleridge's power as a critic of poetry. In this region he stands supreme. With regard to the preface, which contains Wordsworth's theory, Coleridge has honestly expressed his dissent:--"With many parts of this preface, in the sense attributed to them, and which the words undoubtedly seem to authorize, I never concurred; but, on the contrary, objected to them as erroneous in principle, and contradictory (in appearance at least) both to other parts of the same preface, and to the author's own practice in the greater number of the poems themselves." This disclaimer of perfect agreement renders the remaining portion of what he says more valuable. Coleridge was in England the creator of that higher criticism which had already in Germany accomplished so much in the hands of Lessing and Goethe. It is enough to refer here to the fragmentary series of his Shakespearian criticisms, containing evidence of the truest insight, and a marvellous appreciation of the judicial "sanity" which raises the greatest name in literature far above even the highest of the poets who approached him.

As a poet Coleridge's own place is safe. His niche in the great gallery of English poets is secure. Of no one can it be more emphatically said that at his highest he was "of imagination all compact." He does not possess the fiery pulse and humaneness of Burns, but the exquisite perfection of his metre and the subtle alliance of his thought and expression must always secure for him the warmest admiration of true lovers of poetic art. In his early poems may be found traces of the fierce struggle of his youth. The most remarkable is the _Monody on the Death of Chatterton_ and the _Religious Musings_. In what may be called his second period, the ode entitled _France_, considered by Shelley the finest in the language, is most memorable. The whole soul of the poet is reflected in the _Ode to Dejection_. The well-known lines--

"O Lady! we receive but what we give, And in our life alone does nature live; Ours is her wedding garment, ours her shroud,"

with the passage which follows, contain more vividly, perhaps, than anything which Coleridge has written, the expression of the shaping and colouring function which he assigns, in the _Biographia Literaria_, to imagination. _Christabel_ and the _Ancient Mariner_ have so completely taken possession of the highest place, that it is needless to do more than allude to them. The supernatural has never received such treatment as in these two wonderful productions of his genius, and though the first of them remains a torso, it is the loveliest torso in the gallery of English literature. Although Coleridge had, for many years before his death, almost entirely forsaken poetry, the few fragments of work which remain, written in later years, show little trace of weakness, although they are wanting in the unearthly melody which imparts such a charm to _Kubla Khan_, _Love_ and _Youth and Age_. (G. D. B.; H. CH.)

In the latter part of his life, and for the generation which followed, Coleridge was ranked by many young English churchmen of liberal views as the greatest religious thinker of their time. As Carlyle has told in his _Life of Sterling_, the poet's distinction, in the eyes of the younger churchmen with philosophic interests, lay in his having recovered and preserved his Christian faith after having passed through periods of rationalism and Unitarianism, and faced the full results of German criticism and philosophy. His opinions, however, were at all periods somewhat mutable, and it would be difficult to state them in any form that would hold good for the whole even of his later writings. He was, indeed, too receptive of thought impressions of all kinds to be a consistent systematizer. As a schoolboy, by his own account, he was for a time a Voltairean, on the strength of a perusal of the _Philosophical Dictionary_. At college, as we have seen, he turned Unitarian. From that position he gradually moved towards pantheism, a way of thought to which he had shown remarkable leanings when, as a schoolboy, he discoursed of Neo-Platonism to Charles Lamb, or--if we may trust his recollection--translated the hymns of Synesius. Early in life, too, he met with the doctrines of Jacob Behmen, of whom, in the _Biographia Literaria_, he speaks with affection and gratitude as having given him vital philosophic guidance. Between pantheism and Unitarianism he seems to have balanced till his thirty-fifth year, always tending towards the former in virtue of the recoil from "anthropomorphism" which originally took him to Unitarianism. In 1796, when he named his first child David Hartley, but would not have him baptized, he held by the "Christian materialism" of the writer in question, whom in his _Religious Musings_ he terms "wisest of mortal kind."

When, again, he met Wordsworth in 1797, the two poets freely and sympathetically discussed Spinoza, for whom Coleridge always retained a deep admiration; and when in 1798 he gave up his Unitarian preaching, he named his second child Berkeley, signifying a new allegiance, but still without accepting Christian rites otherwise than passively. Shortly afterwards he went to Germany, where he began to study Kant, and was much captivated by Lessing. In the _Biographia_ he avows that the writings of Kant "more than any other work, at once invigorated and disciplined my understanding"; yet the gist of his estimate there is that Kant left his system undeveloped, as regards his idea of the Noumenon, for fear of orthodox persecution--a judgment hardly compatible with any assumption of Kant's Christian orthodoxy, which was notoriously inadequate. But after his stay at Malta, Coleridge announced to his friends that he had given up his "Socinianism" (of which ever afterwards he spoke with asperity), professing a return to Christian faith, though still putting on it a mystical construction, as when he told Crabb Robinson that "Jesus Christ was a Platonic philosopher." At this stage he was much in sympathy with the historico-rationalistic criticism of the Old Testament, as carried on in Germany; giving his assent, for instance, to the naturalistic doctrine of Schiller's _Die Sendung Moses_. From about 1810 onwards, however, he openly professed Christian orthodoxy, while privately indicating views which cannot be so described. And even his published speculations were such as to draw from J. H. Newman a protest that they took "a liberty which no Christian can tolerate," and carried him to "conclusions which were often heathen rather than Christian." This would apply to some of his positions concerning the Logos and the Trinity. After giving up Unitarianism he claimed that from the first he had been a Trinitarian on Platonic lines; and some of his latest statements of the doctrine are certainly more pantheistic than Christian.

The explanation seems to be that while on Christian grounds he repeatedly denounced pantheism as being in all its forms equivalent to atheism, he was latterly much swayed by the thought of Schelling in the pantheistic direction which was natural to him. To these conflicting tendencies were probably due his self-contradictions on the problem of original sin and the conflicting claims of feeling and reason. It would seem that, in the extreme spiritual vicissitudes of his life, conscious alternately of personal weakness and of the largest speculative grasp, he at times threw himself entirely on the consolations of evangelical faith, and at others reconstructed the cosmos for himself in terms of Neo-Platonism and the philosophy of Schelling. So great were his variations even in his latter years, that he could speak to his friend Allsop in a highly latitudinarian sense, declaring that in Christianity "the miracles are supererogatory," and that "the law of God and the great principles of the Christian religion would have been the same had Christ never assumed humanity."

From Schelling, whom he praised as having developed Kant where Fichte failed to do so, he borrowed much and often, not only in the metaphysical sections of the _Biographia_ but in his aesthetic lectures, and further in the cosmic speculations of the posthumous _Theory of Life_. On the first score he makes but an equivocal acknowledgment, claiming to have thought on Schelling's lines before reading him; but it has been shown by Hamilton and Ferrier that besides transcribing much from Schelling without avowal he silently appropriated the learning of Maass on philosophical history. In other directions he laid under tribute Herder and Lessing; yet all the while he cast severe imputations of plagiarism upon Hume and others. His own plagiarisms were doubtless facilitated by the physiological effects of opium.

Inasmuch as he finally followed in philosophy the mainly poetical or theosophic movement of Schelling, which satisfied neither the logical needs appealed to by Hegel nor the new demand for naturalistic induction, Coleridge, after arousing a great amount of philosophic interest in his own country in the second quarter of the century, has ceased to "make a school." Thus his significance in intellectual history remains that of a great stimulator. He undoubtedly did much to deepen and liberalize Christian thought in England, his influence being specially marked in the school of F. D. Maurice, and in the lives of men like John Sterling. And even his many borrowings from the German were assimilated with a rare power of development, which bore fruit not only in a widening of the field of English philosophy but in the larger scientific thought of a later generation. (J. M. RO.)

Of Coleridge's four children, two (Hartley and Sara) are separately noticed. His second child, Berkeley, died when a baby. The third, Derwent (1800-1883), a distinguished scholar and author, was master of Helston school, Cornwall (1825-1841), first principal of St Mark's College, Chelsea (1841-1864), and rector of Hanwell (1864-1880); and his daughter Christabel (b. 1843) and son Ernest Hartley (b. 1846) both became well known in the world of letters, the former as a novelist, the latter as a biographer and critic.

After Coleridge's death several of his works were edited by his nephew, Henry Nelson Coleridge, the husband of Sara, the poet's only daughter. In 1847 Sara Coleridge published the _Biographia Literaria_, enriched with annotations and biographical supplement from her own pen. Three volumes of political writings, entitled _Essays on his Own Times_, were also published by Sara Coleridge in 1850. The standard life of Coleridge is that by J. Dykes Campbell (1894); his letters were edited by E. H. Coleridge.

COLERIDGE, SARA (1802-1852), English author, the fourth child and only daughter of Samuel Taylor Coleridge and his wife Sarah Fricker of Bristol, was born on the 23rd of December 1802, at Greta Hall, Keswick. Here, after 1803, the Coleridges, Southey and his wife (Mrs Coleridge's sister), and Mrs Lovell (another sister), widow of Robert Lovell, the Quaker poet, all lived together; but Coleridge was often away from home; and "Uncle Southey" was a _pater familias_. The Wordsworths at Grasmere were their neighbours. Wordsworth, in his poem, the _Triad_, has left us a description, or "poetical glorification," as Sara Coleridge calls it, of the three girls--his own daughter Dora, Edith Southey and Sara Coleridge, the "last of the three, though eldest born." Greta Hall was Sara Coleridge's home until her marriage; and the little Lake colony seems to have been her only school. Guided by Southey, and with his ample library at her command, she read by herself the chief Greek and Latin classics, and before she was five-and-twenty had learnt French, German, Italian and Spanish.

In 1822 Sara Coleridge published _Account of the Abipones_, a translation in three large volumes of Dobrizhoffer, undertaken in connexion with Southey's _Tale of Paraguay_, which had been suggested to him by Dobrizhoffer's volumes; and Southey alludes to his niece, the translator (canto iii. stanza 16), where he speaks of the pleasure the old missionary would have felt if

".... he could in Merlin's glass have seen By whom his tomes to speak our tongue were taught."

In less grandiloquent terms, Charles Lamb, writing about the _Tale of Paraguay_ to Southey in 1825, says, "How she Dobrizhoffered it all out, puzzles my slender Latinity to conjecture." In 1825 her second work appeared, a translation from the medieval French of the "Loyal Serviteur," _The Right Joyous and Pleasant History of the Feats, Jests, and Prowesses of the Chevalier Bayard, the Good Knight without Fear and without Reproach: By the Loyal Servant_.

In September 1829 at Crosthwaite church, Keswick, after an engagement of seven years' duration, Sara Coleridge was married to her cousin, Henry Nelson Coleridge (1798-1843), younger son of Captain James Coleridge (1760-1836). He was then a chancery barrister in London. The first eight years of her married life were spent in a little cottage in Hampstead. There four of her children were born, of whom two survived. In 1834 Mrs Coleridge published her _Pretty Lessons in Verse for Good Children; with some Lessons in Latin in Easy Rhyme_. These were originally written for the instruction of her own children, and became very popular. In 1837 the Coleridges removed to Chester Place, Regent's Park; and in the same year appeared _Phantasmion, a Fairy Tale_, Sara Coleridge's longest original work. The songs in _Phantasmion_ were much admired at the time by Leigh Hunt and other critics. Some of them, such as "Sylvan Stay" and "One Face Alone," are extremely graceful and musical, and the whole fairy tale is noticeable for the beauty of the story and the richness of its language.

In 1843 Henry Coleridge died, leaving to his widow the unfinished task of editing her father's works. To these she added some compositions of her own, among which are the _Essay on Rationalism, with a special application to the Doctrine of Baptismal_ _Regeneration_, appended to Coleridge's _Aids to Reflection_, a Preface to the _Essays on his Own Times, by S. T. Coleridge_, and the Introduction to the _Biographia Literaria_. During the last few years of her life Sara Coleridge was a confirmed invalid. Shortly before she died she amused herself by writing a little autobiography for her daughter. This, which reaches only to her ninth year, was completed by her daughter, and published in 1873, together with some of her letters, under the title _Memoirs and Letters of Sara Coleridge_. The letters show a cultured and highly speculative mind. They contain many apt criticisms of known people and books, and are specially interesting for their allusions to Wordsworth and the Lake Poets. Sara Coleridge died in London on the 3rd of May 1852.

Her son, Herbert Coleridge (1830-1861), won a double first class in classics and mathematics at Oxford in 1852. He was secretary to a committee appointed by the Philological Society to consider the project of a standard English dictionary, a scheme of which the _New English Dictionary_, published by the Clarendon Press, was the ultimate outcome. His personal researches into the subject were contained in his _Glossarial Index to the Printed English Literature of the Thirteenth Century_ (1859).

COLET, JOHN (1467?-1510), English divine and educationist, the eldest son of Sir Henry Colet (lord mayor of London 1486 and 1495), was born in London about 1467. He was educated at St Anthony's school and at Magdalen College, Oxford, where he took the M.A. degree in 1490. He already held the non-resident rectory of Dennington, Suffolk, and the vicarage of St Dunstan's, Stepney, and was now collated rector of Thurning, Hunts. In 1493 he went to Paris and thence to Italy, studying canon and civil law, patristics and the rudiments of Greek. During his residence abroad he became acquainted with Budaeus (Guillaume Budé) and Erasmus, and with the teaching of Savonarola. On his return to England in 1496 he took orders and settled at Oxford, where he lectured on the epistles of St Paul, replacing the old scholastic method of interpretation by an exegesis more in harmony with the new learning. His methods did much to influence Erasmus, who visited Oxford in 1498, and in after years Erasmus received an annuity from him. Since 1494 he had been prebendary of York, and canon of St Martin le Grand, London. In 1502 he became prebendary of Salisbury, in 1505 prebendary of St Paul's, and immediately afterwards dean of the same cathedral, having previously taken the degree of doctor of divinity. Here he continued his practice of lecturing on the books of the Bible; and he soon afterwards established a perpetual divinity lecture, on three days in each week, in St Paul's church. About the year 1508, having inherited his father's large wealth, Colet formed his plan for the re-foundation of St Paul's school, which he completed in 1512, and endowed with estates of an annual value of £122 and upwards. The celebrated grammarian William Lilly was the first master, and the company of mercers were (in 1510) appointed trustees, the first example of non-clerical management in education. The dean's religious opinions were so much more liberal than those of the contemporary clergy (whose ignorance and corruption he denounced) that they deemed him little better than a heretic; but William Warham, the archbishop, refused to prosecute him. Similarly Henry VIII. held him in high esteem despite his sermons against the French wars. In 1514 he made the Canterbury pilgrimage, and in 1515 preached at Wolsey's installation as cardinal. Colet died of the sweating sickness on the 16th of September 1519. He was buried on the south side of the choir of St Paul's, where a stone was laid over his grave, with no other inscription than his name. Besides the preferments above mentioned, he was rector of the gild of Jesus at St Paul's and chaplain to Henry VIII.

Colet, though never dreaming of a formal breach with the Roman Church, was a keen reformer, who disapproved of auricular confession, and of the celibacy of the clergy. Though no great scholar or writer, he was a powerful force in the England of his day, and helped materially to disintegrate the medieval conditions still obtaining, and to introduce the humanist movement. Among his works, which were first collectively published in 1867-1876, are _Absolutissimus de octo orationis partium constructione libellus_ (Antwerp, 1530), _Rudimenta Grammatices_ (London, 1539), _Daily Devotions_, _Monition to a Godly Life_, _Epistolae ad Erasmum_, and commentaries on different parts of the Bible.

See F. Seebohm, _The Oxford Reformers_; J. H. Lupton, _Life of John Colet_ (1887); art. in _The Times_, July 7, 1909.

COLET, LOUISE (1810-1876), French poet and novelist, was born at Aix of a Provençal family named Revoil, on the 15th of September 1810. In 1835 she came to Paris with her husband Hippolyte Colet (1808-1851), a composer of music and professor of harmony and counterpoint at the conservatoire. In 1836 appeared her _Fleurs du Midi_, a volume of verse, of liberal tendency, followed by _Penserosa_ (1839), a second volume of verse; by _La Jeunesse de Goethe_ (1839), a one-act comedy; by _Les Coeurs brisés_ (1843), a novel; _Les Funerailles de Napoléon_ (1840), a poem, and _La Jeunesse de Mirabeau_ (1841), a novel. Her works were crowned five or six times by the Institute, a distinction which she owed, however, to the influence of Victor Cousin rather than to the quality of her work. The criticisms on her books and on the prizes conferred on her by the Academy exasperated her; and in 1841 Paris was diverted by her attempted reprisals on Alphonse Karr for certain notices in _Les Guêpes_. In 1849 she had to defend an action brought against her by the heirs of Madame Récamier, whose correspondence with Benjamin Constant she had published in the columns of the _Presse_. She produced a host of writings in prose and verse, but she is perhaps best known for her intimate connexion with some of her famous contemporaries, Abel Villemain, Gustave Flaubert and Victor Cousin. Only one of her books is now of interest--_Lui: roman contemporain_ (1859), the novel in which she told the story of her life. She died on the 8th of March 1876.

COLEUS, a genus of herbaceous or shrubby plants belonging to the natural order Labiatae, chiefly natives of the tropics. They are very ornamental plants, the colour of their leaves being exceedingly varied, and often very brilliant. They are of the easiest culture. The cuttings of young shoots should be propagated every year, about March, being planted in thumb pots, in sandy loam, and placed in a close temperature of 70°. After taking root shift into 6-in. pots, using ordinary light loamy compost, containing abundance of leaf-mould and sand, and keeping them near the light. They may be passed on into larger pots as often as required, but 8-in. pots will be large enough for general purposes, as they can be fed with liquid manure. The young spring-struck plants like a warm growing atmosphere, but by midsummer they will bear more air and stand in a greenhouse or conservatory. They should be wintered in a temperature of 60° to 65°. The stopping of the young shoots must be regulated by the consideration whether bushy or pyramidal plants are desired. Some of the varieties are half-hardy and are used for summer bedding.

COLFAX, SCHUYLER (1823-1885), American political leader, vice-president of the United States from 1869 to 1873, was born in New York city on the 23rd of March 1823. His father died before the son's birth, and his mother subsequently married a Mr Matthews. The son attended the public schools of New York until he was ten, and then became a clerk in his step-father's store, removing in 1836 with his mother and step-father to New Carlisle, Indiana. In 1841 he removed to South Bend, where for eight years he was deputy auditor (his step-father being auditor) of St Joseph county; in 1842-1844 he was assistant enrolling clerk of the state senate and senate reporter for the _Indiana State Journal_. In 1845 he established the _St Joseph Valley Register_, which he published for eighteen years and made an influential Whig and later Republican journal. In 1850 he was a member of the state constitutional convention, and in 1854 took an active part in organizing the "Anti-Nebraska men" (later called Republicans) of his state, and was by them sent to Congress. Here he served with distinction from 1855 until 1869, the last six years as speaker of the House. At the close of the Civil War he was a leading member of the radical wing of the Republican party, advocating the disfranchisement of all who had been prominent in the service of the Confederacy, and declaring that "loyalty must govern what loyalty has preserved." In 1868 he had presidential aspirations, and was not without supporters. He accepted, however, the Republican nomination as vice-president on a ticket headed by General Grant, and was elected; but he failed in 1872 to secure renomination. During the political campaign of 1872 he was accused, with other prominent politicians, of being implicated in corrupt transactions with the Crédit Mobilier, and a congressional investigation brought out the fact that he had agreed to take twenty shares from this concern, and had received dividends amounting to $1200. It also leaked out during the investigation that he had received in 1868, as a campaign contribution, a gift of $4000 from a contractor who had supplied the government with envelopes while Colfax was chairman of the post office committee of the House. At the close of his term Colfax returned to private life under a cloud, and during the remainder of his lifetime earned a livelihood by delivering popular lectures. He died at Mankato, Minnesota, on the 13th of January 1885.

COLIC (from the Gr. [Greek: kolon] or [Greek: kôlon], the large intestine), a term in medicine of very indefinite meaning, used by physicians outside England for any paroxysmal abdominal pain, but generally limited in England to a sudden sharp pain having its origin in the pelvis of the kidney, the ureter, gall-bladder, bile-ducts or intestine. Thus it is customary to speak of renal, biliary or intestinal colic. There is a growing tendency, however, among professional men of to-day, to restrict the use of the word to a pain produced by the contraction of the muscular walls of any of the hollow viscera of which the aperture has become more or less occluded, temporarily or otherwise. For renal and biliary colic, see the articles KIDNEY DISEASES and LIVER, only intestinal colic being treated in this place.

In infants, usually those who are "bottle-fed," colic is exceedingly common, and is shown by the drawing up of their legs, their restlessness and their continuous cries.

Among adults one of the most serious causes is that due to lead-poisoning and known as lead colic (_Syn._ painters' colic, _colica Pictonum_, Devonshire colic), from its having been clearly ascertained to be due to the absorption of lead into the system (see LEAD-POISONING). This disease had been observed and described long before its cause was discovered. Its occurrence in an epidemic form among the inhabitants of Poitou was recorded by François Citois (1572-1652) in 1617, under the title of _Novus et popularis apud Pictones dolor colicus biliosus_. The disease was thereafter termed _colica Pictonum_. It was supposed to be due to the acidity of the native wines, but it was afterwards found to depend on lead contained in them. A similar epidemic broke out in certain parts of Germany in the end of the 17th century, and was at the time believed by various physicians to be caused by the admixture of acid wines with litharge to sweeten them.

About the middle of the 18th century this disease, which had long been known to prevail in Devonshire, was carefully investigated by Sir George Baker (1722-1809), who succeeded in tracing it unmistakably to the contamination of the native beverage, cider, with lead, either accidentally from the leadwork of the vats and other apparatus for preparing the liquor, or from its being sweetened with litharge.

In Germany a similar colic resulting from the absorption of copper occurs, but it is almost unknown in England.

The simplest form of colic is that arising from habitual constipation, the muscular wall of the intestines contracting painfully to overcome the resistance of hardened scybalous masses of faeces, which cause more or less obstruction to the onward passage of the intestinal contents. Another equally common cause is that due to irritating or indigestible food such as apples, pears or nuts, heavy pastry, meat pies and puddings, &c. It may then be associated with either constipation or diarrhoea, though the latter is the more common. It may result from any form of enteritis as simple, mucous and ulcerative colitis, or an intestinal malignant growth. The presence of _ascaris lumbricoides_ may, by reflex action, set up a very painful nervous spasm; and certain forms of influenza (q.v.) are ushered in by colic of a very pronounced type. Many physicians describe a rheumatic colic due to cold and damp, and among women disease of the pelvic organs may give rise to an exactly similar pain. There are also those forms of colic which must be classed as functional or neuralgic, though this view of the case must never be accepted until every other possible cause is found to be untenable. From this short account of a few of the commoner causes of the trouble, it will be clear that colic is merely a symptom of disease, not a disease in itself, and that no diagnosis has been made until the cause of the pain has been determined.

Intestinal colic is paroxysmal, usually both beginning and ending suddenly. The pain is generally referred to the neighbourhood of the umbilicus, and may radiate all over the abdomen. It varies in intensity from a slight momentary discomfort to a pain so severe as to cause the patient to shriek or even to break out into a cold clammy sweat. It is usually relieved by pressure, and this point is one which aids in the differential diagnosis between a simple colic and peritonitis, the pain of the latter being increased by pressure. But should the colic be due to a malignant growth, or should the intestines be distended with gas, pressure will probably increase the pain. The temperature is usually subnormal, but may be slightly raised, and the pulse is in proportion.

In the treatment of simple colic the patient must be confined to bed, hot fomentations applied to the abdomen and a purge administered, a few drops of laudanum being added when the pain is exceptionally severe. But the whole difficulty lies in making the differential diagnosis. Acute intestinal obstruction (ileus) begins just as an attack of simple colic, but the rapid increase of illness, frequent vomiting, anxious countenance, and still more the condition of the pulse, warn a trained observer of the far more serious state. Appendicitis and peritonitis, as also the gastric crises of locomotor ataxy, must all be excluded.

COLIGNY, GASPARD DE (1519-1572), admiral of France and Protestant leader, came of a noble family of Burgundy, who traced their descent from the 11th century, and in the reign of Louis XI. were in the service of the king of France. His father, Gaspard de Coligny, known as the maréchal de Châtillon (d. 1522), served in the Italian wars from 1495 to 1515, and was created marshal of France in 1516. By his wife, Louise de Montmorency, sister of the future constable, he had three sons: Odet, cardinal de Châtillon; Gaspard, the admiral; and Francis, seigneur d'Andelot; all of whom played an important part in the first period of the wars of religion. At twenty-two young Gaspard came to court, and there contracted a friendship with Francis of Guise. In the campaign of 1543 Coligny distinguished himself greatly, and was wounded at the sieges of Montmédy and Bains. In 1544 he served in the Italian campaign under the duke of Enghien, and was knighted on the field of Ceresole. Returning to France, he took part in different military operations; and having been made colonel-general of the infantry (April 1547), exhibited great capacity and intelligence as a military reformer. He was made admiral on the death of d'Annebaut (1552). In 1557 he was entrusted with the defence of Saint Quentin. In the siege he displayed great courage, resolution, and strength of character; but the place was taken, and he was imprisoned in the stronghold of L'Ecluse. On payment of a ransom of 50,000 crowns he recovered his liberty. But he had by this time become a Huguenot, through the influence of his brother, d'Andelot--the first letter which Calvin addressed to him is dated the 4th of September 1558--and he busied himself secretly with protecting his co-religionists, a colony of whom he sent to Brazil, whence they were afterwards expelled by the Portuguese.

On the death of Henry II. he placed himself, with Louis, prince of Condé, in the front of his sect, and demanded religious toleration and certain other reforms. In 1560, at the Assembly of Notables at Fontainebleau, the hostility between Coligny and Francis of Guise broke forth violently. When the civil wars began in 1562, Coligny decided to take arms only after long hesitation, and he was always ready to negotiate. In none of these wars did he show superior genius, but he acted throughout with great prudence and extraordinary tenacity; he was "le héros de la mauvaise fortune." In 1569 the defeat and death of the prince of Condé at Jarnac left him sole leader of the Protestant armies. Victorious at Arnay-le-Duc, he obtained in 1570 the pacification of St Germain. Returning to the court in 1571, he grew rapidly in favour with Charles XI. As a means of emancipating the king from the tutelage of his mother and the faction of the Guises, the admiral proposed to him a descent on Spanish Flanders, with an army drawn from both sects and commanded by Charles in person. The king's regard for the admiral, and the bold front of the Huguenots, alarmed the queen-mother; and the massacre of St Bartholomew was the consequence. On the 22nd of August 1572 Coligny was shot in the street by Maurevel, a bravo in the pay of the queen-mother and Guise; the bullets, however, only tore a finger from his right hand and shattered his left elbow. The king visited him, but the queen-mother prevented all private intercourse between them. On the 24th of August, the night of the massacre, he was attacked in his house, and a servant of the duke of Guise, generally known as Besme, slew him and cast him from a window into the courtyard at his master's feet. His papers were seized and burned by the queen-mother; among them, according to Brantôme, was a history of the civil war, "très-beau et tres-bien faict, et digne d'estre imprimé."

By his wife, Charlotte de Laval, Coligny had several children, among them being Louise, who married first Charles de Téligny and afterwards William the Silent, prince of Orange, and Francis, admiral of Guienne, who was one of the devoted servants of Henry IV. Gaspard de Coligny (1584-1646), son of Francis, was marshal of France during the reign of Louis XIII.

COLIMA, a small Pacific coast state of Mexico, lying between Jalisco on the N.W. and N., and Michoacan on the E. Including the Revilla Gigédo islands its area is only 2272 sq. m., which thus makes it the second smallest of the Mexican states. Pop. (1895) 55,264; (1900) 65,115. The larger part of its territory is within the narrow, flat coastal plain, beyond which it rises toward the north-east into the foothills of the Sierra Madre, the higher masses of the range, including the Colima volcano, lying outside the state. It is drained by the Ameria and Coahuayana rivers and their affluents, which are largely used for irrigation. There are tidewater lagoons and morasses on the coast which accentuate its malarious character. One of the largest of these, Cuitlán, immediately south of Manzanillo, is the centre of a large salt-producing industry. The soil is generally fertile and productive, but lack of transportation facilities has been a serious obstacle to any production greatly exceeding local demands. The dry and rainy seasons are sharply defined, the rainfall being abundant in the latter. The climate is hot, humid and malarious, becoming drier and healthier on the higher mountain slopes of the interior. Stock-raising is an important industry in the higher parts of the state, but the horses, mules and cattle raised have been limited to local demands. Agriculture, however, is the principal occupation of the state, the more important products being sugar, rice, Indian corn, palm oil, coffee, indigo, cotton and cacao. The production of cacao is small, and that of indigo and cotton is declining, the latter being limited to the requirements of small local mills. There are two crops of Indian corn a year, but sugar and rice are the principal crops. The "Caracolillo" coffee, produced on the slopes of the mountains culminating in the volcano of Colima, is reputed the best in Mexico, and the entire crop (about 506,000 lb. in 1906) is consumed in the country at a price much above other grades. There are important mineral deposits in the state, including iron, copper and lead, but mining enterprise has made no progress through lack of transportation facilities. Salt is made on the coast and shipped inland, and palm-leaf hats are manufactured and exported. Hides and deerskins are also exported in large quantities. A narrow-gauge railway has been in operation between the capital and Manzanillo for many years, and in 1907 a branch of the Mexican Central was completed between Guadalajara and the capital, and the narrow-gauge line to the coast was widened to the standard gauge. The chief cities of the state are the capital Colima, Manzanillo, Comala (the second largest town in the state), 5 m. from the capital, with which it is connected by an electric railway, Ixtlahuacan Coquimatlan and Almoloyan.

COLIMA, a city of Mexico and capital of a state of the same name, 570 m. (direct) W. by S. of Mexico City and about 36 m. inland from the Pacific coast. Pop. (1895) 18,977; (1900) 20,698. Colima is picturesquely situated on the Colima river, in a large fertile valley about 1650 ft. above the sea, and lies in the midst of fine mountain-scenery. About 30 m. to the north-east the volcano of Colima, in the state of Jalisco, rises to an elevation of 12,685 ft.; it is the most westerly of the active volcanoes of Mexico. Colima enjoys a moderately cool and healthy climate, especially in the dry season (November to June). The city is regularly laid out and is in great part well built, with good public buildings, several churches, a theatre, two hospitals, and a handsome market completed in 1905. Tramways connect the central plaza with the railway station, cemetery, and the suburb of Villa de Alvarez, 2½ m. distant, and an extension of 5 m. was projected in 1906 to Comala. The local industries include two old-fashioned cotton mills, an ice plant, corn-grinding mill, and five cigarette factories. Colima is the commercial centre for a large district, but trade has been greatly restricted by lack of transportation facilities. A railway connects with the port of Manzanillo, and the Mexican Central railway serves Colima itself. Colima was founded in 1522 by Gonzalo de Sandoval. It has not played a very prominent part in Mexican history because of its inaccessibility, and for the same reason has suffered less from revolutionary violence.

COLIN, ALEXANDRE (1526-1612), Flemish sculptor, was born at Malines. In 1563 he went, at the invitation of the emperor Ferdinand I., to Innsbruck, to work on the magnificent monument which was being erected to Maximilian I. in the nave of the Franciscan church. Of the twenty-four marble alti-rilievi, representing the emperor's principal acts and victories, which adorn the sides of this tomb, twenty were executed by Colin, apparently in three years. The work displays a remarkable combination of liveliness and spirit with extreme care and finish, its delicacy rivalling that of a fine cameo. Thorwaldsen is said to have pronounced it the finest work of its kind. Colin, who was sculptor in ordinary both to the emperor and to his son, the archduke Ferdinand of Tirol, did a great deal of work for his patrons at Innsbruck and in its neighbourhood; particular mention may be made of the sepulchres of the archduke and his first wife, Philippine Welser, both in the same church as the Maximilian monument, and of Bishop Jean Nas. His tomb in the cemetery at Innsbruck bears a fine bas-relief executed by one of his sons.

COLL, an island of the Inner Hebrides, Argyllshire, Scotland. Pop. (1901) 432. It is situated about 7 m. west of Caliach Point in Mull, and measures 12 m. from N.E. to S.W., with a breadth varying from ¾ m. to 4
