c. 1540), a native of Dijon, and pupil of Leonardo da Vinci, but the

sculpture of the portals, including "The Last Judgment" on the tympanum of the main portal, is probably from his hand. St Jean (15th century) and St Étienne (15th, 16th and 17th centuries), now used as the exchange, are the other chief churches. Of the ancient palace of the dukes of Burgundy there remain two towers, the Tour de la Terrasse and the Tour de Bar, the guard-room and the kitchens; these now form part of the hôtel de ville, the rest of which belongs to the 17th and 18th centuries. This building contains an archaeological museum with a collection of Roman stone monuments; the archives of the town; and the principal museum, which, besides valuable paintings and other works of art, contains the magnificent tombs of Philip the Bold and John the Fearless, dukes of Burgundy. These were transferred from the Chartreuse of Dijon (or of Champmol), built by Philip the Bold as a mausoleum, now replaced by a lunatic asylum. Relics of it survive in the old Gothic entrance, the portal of the church, a tower and the well of Moses, which is adorned with statues of Moses and the prophets by Claux Sluter (fl. end of 14th century), the Dutch sculptor, who also designed the tomb of Philip the Bold. The Palais de Justice, which belongs to the reign of Louis XII., is of interest as the former seat of the _parlement_ of Burgundy. Dijon possesses several houses of the 15th, 16th and 17th centuries, notably the Maison Richard in the Gothic, and the Hôtel Vogüé in the Renaissance style. St Bernard, the composer J. P. Rameau and the sculptor François Rude have statues in the town, of which they were natives. There are also monuments to those inhabitants of Dijon who fell in the engagement before the town in 1870, and to President Carnot and Garibaldi.

The town is important as the seat of a prefecture, a bishopric, a court of appeal and a court of assizes, and as centre of an académie (educational district). There are tribunals of first instance and of commerce, a board of trade-arbitrators, a chamber of commerce, an exchange (occupying the former cathedral of St Étienne), and an important branch of the Bank of France. Its educational establishments include faculties of law, of science and of letters, a preparatory school of medicine and pharmacy, a higher school of commerce, a school of fine art, a conservatoire of music, _lycées_ and training colleges, and there is a public library with about 100,000 volumes.

Dijon is well known for its mustard, and for the black currant liqueur called _cassis de Dijon_; its industries include the manufacture of machinery, automobiles, bicycles, soap, biscuits, brandy, leather, boots and shoes, candles and hosiery. There are also flour mills, breweries, important printing works, vinegar works and, in the vicinity, nursery gardens. The state has a large tobacco manufactory in the town. Dijon has considerable trade in cereals and wool, and is the second market for the wines of Burgundy.

Under the Romans Dijon (_Divonense castrum_) was a _vicus_ in the _civitas_ of Langres. In the 2nd century it was the scene of the martyrdom of St Benignus (Bénigne, vulg. Berin, Berain), the apostle of Burgundy. About 274 the emperor Aurelian surrounded it with ramparts. Gregory of Tours, in the 6th century, comments on the strength and pleasant situation of the place, expressing surprise that it does not rank as a _civitas_. During the middle ages the fortunes of Dijon followed those of Burgundy, the dukes of which acquired it early in the 11th century. The communal privileges, conferred on the town in 1182 by Hugh III., duke of Burgundy, were confirmed by Philip Augustus in 1183, and in the 13th century the dukes took up their residence there. For the decoration of the palace and other monuments built by them, eminent artists were gathered from northern France and Flanders, and during this period the town became one of the great intellectual centres of France. The union of the duchy with the crown in 1477 deprived Dijon of the splendour of the ducal court; but to counterbalance this loss it was made the capital of the province and seat of a _parlement_. Its fidelity to the monarchy was tested in 1513, when the citizens were besieged by 50,000 Swiss and Germans, and forced to agree to a treaty so disadvantageous that Louis XII. refused to ratify it. In the wars of religion Dijon sided with the League, and only opened its gates to Henry IV. in 1595. The 18th century was a brilliant period for the city; it became the seat of a bishopric, its streets were improved, its commerce developed, and an academy of science and letters founded; while its literary salons were hardly less celebrated than those of Paris. The neighbourhood was the scene of considerable fighting during the Franco-German War, which was, however, indirectly of some advantage to the city owing to the impetus given to its industries by the immigrants from Alsace.

See H. Chabeuf, _Dijon à travers les âges_ (Dijon, 1897), and _Dijon, monuments et souvenirs_ (Dijon, 1894).

DIKE, or DYKE (Old Eng. _dic_, a word which appears in various forms in many Teutonic languages, cf. Dutch _dijk_, German _Teich_, Danish _dige_, and in French, derived from Teutonic, _digue_; it is the same word as "ditch" and is ultimately connected with the root of "dig"), properly a trench dug out of the earth for defensive and other purposes. Water naturally collects in such trenches, and hence the word is applied to natural and artificial channels filled with water, as appears in the proverbial expression "February fill-dyke," and in the names of many narrow waterways in East Anglia. "Dike" also is naturally used of the bank of earth thrown up out of the ditch, and so of any embankment, dam or causeway, particularly the defensive works in Holland, the Fen district of England, and other low-lying districts which are liable to flooding by the sea or rivers (see HOLLAND and FENS). In Scotland any wall, fence or even hedge, used as a boundary is called a dyke. In geology the term is applied to wall-like masses of rock (sometimes projecting beyond the surrounding surface) which fill up vertical or highly inclined fissures in the strata.

DIKKA, a term in Mahommedan architecture for the tribune raised upon columns, from which the Koran is recited and the prayers intoned by the Imam of the mosque.

DILAPIDATION (Lat. for "scattering the stones," _lapides_, of a building), a term meaning in general a falling into decay, but more particularly used in the plural in English law for (1) the waste committed by the incumbent of an ecclesiastical living; (2) the disrepair for which a tenant is usually liable when he has agreed to give up his premises in good repair (see EASEMENT; FLAT; LANDLORD AND TENANT). By the general law a tenant for life has no power to cut down timber, destroy buildings, &c., (voluntary waste), or to let buildings fall into disrepair (permissive waste). In the eye of the law an incumbent of a living is a tenant for life of his benefice, and any waste, voluntary or permissive, on his part must be made good by his administrators to his successor in office. The principles on which such dilapidations are to be ascertained, and the application of the money payable in respect thereof, depend partly on old ecclesiastical law and partly on acts of parliament. Questions as to ecclesiastical dilapidations usually arise in respect of the residence house and other buildings belonging to the living. Inclosures, hedges, ditches and the like are included in things "of which the beneficed person hath the burden and charge of reparation." In a leading case (_Ross_ v. _Adcock_, 1868, L.R. 3 C.P. 657) it was said that the court was acquainted with no precedent or decision extending the liability of the executors of a deceased incumbent to any species of waste beyond dilapidation of the house, chancel or other buildings or fences of the benefice. And it has been held that the mere mismanagement or miscultivation of the ecclesiastical lands will not give rise to an action for dilapidations. To place the law relating to dilapidations on a more satisfactory footing, the Ecclesiastical Dilapidations Act 1871 was passed. The buildings to which the act applies are defined to be such houses of residence, chancels, walls, fences and other buildings and things as the incumbent of the benefice is by law and custom bound to maintain in repair. In each diocese a surveyor is appointed by the archdeacons and rural deans subject to the approval of the bishop; and such surveyor shall by the direction of the bishop examine the buildings on the following occasions--viz. (1) when the benefice is sequestrated; (2) when it is vacant; (3) at the request of the incumbent or on complaint by the archdeacon, rural dean or patron. The surveyor specifies the works required, and gives an estimate of their probable cost. In the case of a vacant benefice, the new incumbent and the old incumbent or his representatives may lodge objections to the surveyor's report on any grounds of fact or law, and the bishop, after consideration, may make an order for the repairs and their cost, for which the late incumbent or his representatives are liable. The sum so stated becomes a debt due from the late incumbent or his representatives to the new incumbent, who shall pay over the money when recovered to the governors of Queen Anne's Bounty. The governors pay for the works on execution on receipt of a certificate from the surveyor; and the surveyor, when the works have been completed to his satisfaction, gives a certificate to that effect, the effect of which, so far as regards the incumbent, is to protect him from liability for dilapidations for the next five years. Unnecessary buildings belonging to a residence house may, by the authority of the bishop and with the consent of the patron, be removed. An amending statute of 1872 (Ecclesiastical Dilapidations Act (1871) Amendment) relates chiefly to advances by the governors of Queen Anne's Bounty for the purposes of the act.

DILATATION (from Lat. _dis-_, distributive, and _latus_, wide), a widening or enlarging; a term used in physiology, &c.

DILATORY (from Lat. _dilatus_, from _differre_, to put off or delay), delaying, or slow; in law a "dilatory plea" is one made merely for delaying the suit.

DILEMMA (Gr. [Greek: dilêmma], a double proposition, from [Greek: di-] and [Greek: lambanein]), a term used technically in logic, and popularly in common parlance and rhetoric. (1) The latter use has no exact definition, but in general it describes a situation wherein from either of two (or more) possible alternatives an unsatisfactory conclusion results. The alternatives are called the "horns" of the dilemma. Thus a nation which has to choose between bankruptcy and the repudiation of its debts is on the horns of a dilemma. (2) In logic there is considerable divergence of opinion as to the best definition. Whately defined it as "a conditional syllogism with two or more antecedents in the major and a disjunctive minor." Aulus Gellius gives an example as follows:--"Women are either fair or ugly; if you marry a fair woman, she will attract other men; if an ugly woman she will not please you; therefore marriage is absurd." From either alternative, an unpleasant result follows. Four kinds of dilemma are admitted:--(a) _Simple Constructive_: If A, then C; if B, then C, but either B or A; therefore C. (b) _Simple Destructive_: If A is true, B is true; if A is true, C is true; B and C are not both true; therefore A is not true. (c) _Complex Constructive_: If A, then B; if C, then D; but either A or C; therefore either B or D. (d) _Complex Destructive_: If A is true, B is true; if C is true, D is true; but B and D are not both true; hence A and C are not both true. The soundness of the dilemmatic argument in general depends on the alternative possibilities. Unless the alternatives produced exhaust the possibilities of the case, the conclusion is invalid. The logical form of the argument makes it especially valuable in public speaking, before uncritical audiences. It is, in fact, important rather as a rhetorical subtlety than as a serious argument.

_Dilemmist_ is also a term used to translate _Vaibhashikas_, the name of a Buddhist school of philosophy.

DILETTANTE, an Italian word for one who delights in the fine arts, especially in music and painting, so a lover of the fine arts in general. The Ital. _dilettare_ is from Lat. _delectare_, to delight. Properly the word refers to an "amateur" as opposed to a "professional" cultivation of the arts, but like "amateur" it is often used in a depreciatory sense for one who is only a dabbler, or who only has a superficial knowledge or interest in art. The Dilettanti Society founded in 1733-1734 still exists in England. A history of the society, by Lionel Cust, was published in 1898.

DILIGENCE, in law, the care which a person is bound to exercise in his relations with others. The possible degrees of diligence are of course numerous, and the same degree is not required in all cases. Thus a mere depositary would not be held bound to the same degree of diligence as a person borrowing an article for his own use and benefit. Jurists, following the divisions of the civil law, have concurred in fixing three approximate standards of diligence--viz. ordinary (_diligentia_), less than ordinary (_levissima diligentia_) and more than ordinary (_exactissima diligentia_). Ordinary or common diligence is defined by Story (_On Bailments_) as "that degree of diligence which men in general exert in respect of their own concerns." So Sir William Jones:--"This care, which every person of common prudence and capable of governing a family takes of his own concerns, is a proper measure of that which would uniformly be required in performing every contract, if there were not strong reasons for exacting in some of them a greater and permitting in others a less degree of attention" (_Essay on Bailments_). The highest degree of diligence would be that which only very prudent persons bestow on their own concerns; the lowest, that which even careless persons bestow on their own concerns. The want of these various degrees of diligence is negligence in corresponding degrees. These approximations indicate roughly the greater or less severity with which the law will judge the performance of different classes of contracts; but English judges have been inclined to repudiate the distinction as a useless refinement of the jurists. Thus Baron Rolfe could see no difference between negligence and gross negligence; it was the same thing with the addition of a vituperative epithet. See NEGLIGENCE.

_Diligence_, in Scots law, is a general term for the process by which persons, lands or effects are attached on execution, or in security for debt.

DILKE, SIR CHARLES WENTWORTH, Bart. (1810-1869), English politician, son of Charles Wentworth Dilke, proprietor and editor of _The Athenaeum_, was born in London on the 18th of February 1810, and was educated at Westminster school and Trinity Hall, Cambridge. He studied law, and in 1834 took his degree of LL.B., but did not practise. He assisted his father in his literary work, and was for some years chairman of the council of the Society of Arts, besides taking a prominent part in the affairs of the Royal Horticultural Society and other bodies. He was one of the most zealous promoters of the Great Exhibition (1851), and a member of the executive committee. At the close of the exhibition he was honoured by foreign sovereigns, and the queen offered him knighthood, which, however, he did not accept; he also declined a large remuneration offered by the royal commission. In 1853 Dilke was one of the English commissioners at the New York Industrial Exhibition, and prepared a report on it. He again declined to receive any money reward for his services. He was appointed one of the five royal commissioners for the Great Exhibition of 1862; and soon after the death of the prince consort he was created a baronet. In 1865 he entered parliament as member for Wallingford. In 1869 he was sent to Russia as representative of England at the horticultural exhibition held at St Petersburg. His health, however, had been for some time failing, and he died suddenly in that city, on the 10th of May 1869. A selection from his writings, _Papers of a Critic_ (2 vols., 1875), contains a biographical sketch by his son.

His son, SIR CHARLES WENTWORTH DILKE, BART. (1843- ), became a prominent Liberal politician, as M.P. for Chelsea (1868-1886), under-secretary for foreign affairs (1880-1882), and president of the local government board (1882-1885); and he was then marked out as one of the best-informed and ablest of the advanced Radicals. He was chairman of the royal commission on the housing of the working classes in 1884-1885. But his sensational appearance as co-respondent in a divorce case of a peculiarly unpleasant character in 1885 cast a cloud over his career. He was defeated in Chelsea in 1886, and did not return to parliament till 1892, when he was elected for the Forest of Dean; and though his knowledge of foreign affairs and his powers as a critic and writer on military and naval questions were admittedly of the highest order, his official position in public life could not again be recovered. His military writings are _The British Army_ (1888); _Army Reform_ (1898) and, with Mr Spenser Wilkinson, _Imperial Defence_ (1892). On colonial questions he wrote with equal authority. His _Greater Britain_ (2 vols., 1866-1867) reached a fourth edition in 1868, and was followed by _Problems of Greater Britain_ (2 vols., 1890) and _The British Empire_ (1899). He was twice married, his second wife (née Emilia Frances Strong), the widow of Mark Pattison, being an accomplished art critic and collector. She died in 1904. The most important of her books were the studies on _French Painters of the Eighteenth Century_ (1899) and three subsequent volumes on the architects and sculptors, furniture and decoration, engravers and draughtsmen of the same period, the last of which appeared in 1902. A posthumous volume, _The Book of the Spiritual Life_ (1905), contains a memoir of her by Sir Charles Dilke.

DILL (_Anethum_ or _Peucedanum graveolens_), a member of the natural botanical order Umbelliferae, indigenous to the south of Europe, Egypt and the Cape of Good Hope. It resembles fennel in appearance. Its root is long and fusiform; the stem is round, jointed and about a yard high; the leaves have fragrant leaflets; and the fruits are brown, oval and concavo-convex. The plant flowers from June till August in England. The seeds are sown, preferably as soon as ripe, either broadcast or in drills between 6 and 12 in. asunder. The young plants should be thinned when 3 or 4 weeks old, so as to be at distances of about 10 in. A sheltered spot and dry soil are needed for the production of the seed in the climate of England. The leaves of the dill are used in soups and sauces, and, as well as the umbels, for flavouring pickles. The seeds are employed for the preparation of dill-water and oil of dill; they are largely consumed in the manufacture of gin, and, when ground, are eaten in the East as a condiment. The British Pharmacopoeia contains the Aqua Anethi or dill-water (dose 1-2 oz.), and the Oleum Anethi, almost identical in composition with caraway oil, and given in doses of ½-3 minims. Dill-water is largely used as a carminative for children, and as a vehicle for the exhibition of nauseous drugs.

DILLEN [DILLENIUS], JOHANN JAKOB (1684-1747), English botanist, was born at Darmstadt in 1684, and was educated at the university of Giessen, where he wrote several botanical papers for the _Ephemerides naturae curiosorum_, and printed, in 1719, his _Catalogus plantarum sponte circa Gissam nascentium_, illustrated with figures drawn and engraved by his own hand, and containing descriptions of many new species. In 1721, at the instance of the botanist William Sherard (1659-1728), he came to England, and in 1724 he published a new edition of Ray's _Synopsis stirpium Britannicarum_. In 1732 he published _Hortus Elthamensis_, a catalogue of the rare plants growing at Eltham, Kent, in the collection of Sherard's younger brother, James (1666-1738), who, after making a fortune as an apothecary, devoted himself to gardening and music. For this work Dillen himself executed 324 plates, and it was described by Linnaeus, who spent a month with him at Oxford in 1736, and afterwards dedicated his _Critica botanica_ to him, as "opus botanicum quo absolutius mundus non vidit." In 1734 he was appointed Sherardian professor of botany at Oxford, in accordance with the will of W. Sherard, who at his death in 1728 left the university £3000 for the endowment of the chair, as well as his library and herbarium. Dillen, who was also the author of an _Historia muscorum_ (1741), died at Oxford, of apoplexy, on the 2nd of April 1747. His manuscripts, books and collections of dried plants, with many drawings, were bought by his successor at Oxford, Dr Humphry Sibthorp (1713-1797), and ultimately passed into the possession of the university.

For an account of his collections preserved at Oxford, see _The Dillenian Herbaria_, by G. Claridge Druce (Oxford, 1907).

DILLENBURG, a town of Germany, in the Prussian province of Hesse-Nassau, delightfully situated in the midst of a well-wooded country, on the Dill, 25 m. N.W. from. Giessen on the railway to Troisdorf. Pop. 4500. On an eminence above it lie the ruins of the castle of Dillenburg, founded by Count Henry the Rich of Nassau, about the year 1255, and the birthplace of Prince William of Orange (1533). It has an Evangelical church, with the vault of the princes of Nassau-Dillenburg, a Roman Catholic church, a classical school, a teachers' seminary and a chamber of commerce. Its industries embrace iron-works, tanneries and the manufacture of cigars. Owing to its beautiful surroundings Dillenburg has become a favourite summer resort.

DILLENS, JULIEN (1849-1904), Belgian sculptor, was born at Antwerp on the 8th of June 1849, son of a painter. He studied under Eugène Simonis at the Brussels Academy of Fine Arts. In 1877 he received the _prix de Rome_ for "A Gaulish Chief taken Prisoner by the Romans." At Brussels, in 1881, he executed the groups entitled "Justice" and "Herkenbald, the Brussels Brutus." For the pediment of the orphanage at Uccle, "Figure Kneeling" (Brussels Gallery), and the statue of the lawyer Metdepenningen in front of the Palais de Justice at Ghent, he was awarded the medal of honour in 1889 at the Paris Universal Exhibition, where, in 1900, his "Two Statues of the Anspach Monument" gained him a similar distinction. For the town of Brussels he executed "The Four Continents" (Maison du Renard, Grand' Place), "The Lansquenets" crowning the lucarnes of the Maison de Roi, and the "Monument t' Serclaes" under the arcades of the Maison de l'Etoile, and, for the Belgian government, "Flemish Art," "German Art," "Classic Art" and "Art applied to Industry" (all in the Palais des Beaux Arts, Brussels), "The Laurel" (Botanic Garden, Brussels), and the statue of "Bernard van Orley" (Place du petit Sablon, Brussels). Mention must also be made of "An Enigma" (1876), the bronze busts of "Rogier de la Pasture" and "P. P. Rubens" (1879), "Etruria" (1880), "The Painter Leon Frederic" (1888), "Madame Leon Herbo," "Hermes," a scheme of decoration for the ogival façade of the hôtel de ville at Ghent (1893), "The Genius of the Funeral Monument of the Moselli Family," "The Silence of Death" (for the entrance of the cemetery of St Gilles), two caryatides for the town hall of St Gilles, presentation plaquette to Dr Heger, medals of MM. Godefroid and Vanderkindere and of "The Three Burgomasters of Brussels," and the ivories "Allegretto," "Minerva" and the "Jamaer Memorial." Dillens died at Brussels in November 1904.

DILLINGEN, a town of Germany, in the kingdom of Bavaria, on the left bank of the Danube, 25 m. N.E. from Ulm, on the railway to Ingolstadt. Pop. (1905) 6078. Its principal buildings are an old palace, formerly the residence of the bishops of Augsburg and now government offices, a royal gymnasium, a Latin school with a library of 75,000 volumes, seven churches (six Roman Catholic), two episcopal seminaries, a Capuchin monastery, a Franciscan convent and a deaf and dumb asylum. The university, founded in 1549, was abolished in 1804, being converted into a lyceum. The inhabitants are engaged in cattle-rearing, the cultivation of corn, hops and fruit, shipbuilding and the shipping trade, and the manufacture of cloth, paper and cutlery. In the vicinity is the Karolinen canal, which cuts off a bend in the Danube between Lauingen and Dillingen. In 1488 Dillingen became the residence of the bishops of Augsburg; was taken by the Swedes in 1632 and 1648, by the Austrians in 1702, and on the 17th of June 1800 by the French. In 1803 it passed to Bavaria.

DILLMANN, CHRISTIAN FRIEDRICH AUGUST (1823-1894), German orientalist and biblical scholar, the son of a Württemberg schoolmaster, was born at Illingen on the 25th of April 1823. He was educated at Tübingen, where he became a pupil and friend of Heinrich Ewald, and studied under F. C. Baur, though he did not join the new Tübingen school. For a short time he worked as pastor at Gersheim, near his native place, but he soon came to feel that his studies demanded his whole time. He devoted himself to the study of Ethiopic MSS. in the libraries of Paris, London and Oxford, and this work caused a revival of Ethiopic study in the 19th century. In 1847 and 1848 he prepared catalogues of the Ethiopic MSS. in the British Museum and the Bodleian library at Oxford. He then set to work upon an edition of the Ethiopic bible. Returning to Tübingen in 1848, in 1853 he was appointed professor extraordinarius. Subsequently he became professor of philosophy at Kiel (1854), and of theology at Giessen (1864) and Berlin (1869). He died on the 4th of July 1894.

In 1851 he had published the _Book of Enoch_ in Ethiopian (German, 1853), and at Kiel he completed the first part of the Ethiopic bible, _Octateuchus Aethiopicus_ (1853-1855). In 1857 appeared his _Grammatik der äthiopischen Sprache_ (2nd ed. by C. Bezold, 1899); in 1859 the _Book of Jubilees_; in 1861 and 1871 another part of the Ethiopic bible, _Libri Regum_; in 1865 his great _Lexicon linguae aethiopicae_; in 1866 his _Chrestomathia aethiopica_. Always a theologian at heart, however, he returned to theology in 1864. His Giessen lectures were published under the titles, _Ursprung der alttestamentlichen Religion_ (1865) and _Die Propheten des alten Bundes nach ihrer politischen Wirksamkeit_ (1868). In 1869 appeared his _Commentar zum Hiob_ (4th ed. 1891) which stamped him as one of the foremost Old Testament exegetes. His renown as a theologian, however, was mainly founded by the series of commentaries, based on those of August Wilhelm Knobels' _Genesis_ (Leipzig, 1875; 6th ed. 1892; Eng. trans, by W. B. Stevenson, Edinburgh, 1897); _Exodus und Leviticus_, 1880, revised edition by V. Ryssel, 1897; _Numeri, Deuteronomium und Josua_, with a dissertation on the origin of the Hexateuch, 1886; _Jesaja_, 1890 (revised edition by Rudolf Kittel in 1898). In 1877 he published the _Ascension of Isaiah_ in Ethiopian and Latin. He was also a contributor to D. Schenkel's _Bibellexikon_, Brockhaus's _Conversationslexikon_, and Herzog's _Realencyklopädie_. His lectures on Old Testament theology, _Vorlesungen über Theologie des Allen Testamentes_, were published by Kittel in 1895.

See the articles in Herzog-Hauck, _Realencyklopädie_, and the _Allgemeine deutsche Biographie_; F. Lichtenberger, _History of German Theology in the Nineteenth Century_ (1889); Wolf Baudissin, _A. Dillmann_ (Leipzig, 1895).

DILLON, ARTHUR RICHARD (1721-1807), French archbishop, was the son of Arthur Dillon (1670-1733), an Irish gentleman who became general in the French service. He was born at St Germain, entered the priesthood and was successively curé of Elan near Mezières, vicar-general of Pontoise (1747), bishop of Evreux (1753) and archbishop of Toulouse (1758), archbishop of Narbonne in 1763, and in that capacity, president of the estates of Languedoc. He devoted himself much less to the spiritual direction of his diocese than to its temporal welfare, carrying out many works of public utility, bridges, canals, roads, harbours, &c.; had chairs of chemistry and of physics created at Montpellier and at Toulouse, and tried to reduce the poverty, especially in Narbonne. In 1787 and in 1788 he was a member of the Assembly of Notables called together by Louis XVI., and in 1788 presided over the assembly of the clergy. Having refused to accept the civil constitution of the clergy, Dillon had to leave Narbonne in 1790, then to emigrate to Coblenz in 1791. Soon afterwards he went to London, where he lived until his death in 1807, never accepting the Concordat, which had suppressed his archiepiscopal see.

See L. Audibret, _Le Dernier Président des États du Languedoc, Mgr. Arthur Richard Dillon, archevêque de Narbonne_ (Bordeaux, 1868); L. de Lavergne, _Les Assemblées provinciales sous Louis XVI_ (Paris, 1864).

DILLON, JOHN (1851- ), Irish nationalist politician, was the son of John Blake Dillon (1816-1866), who sat in parliament for Tipperary, and was one of the leaders of "Young Ireland." John Dillon was educated at the Roman Catholic university of Dublin, and afterwards studied medicine. He entered parliament in 1880 as member for Tipperary, and was at first an ardent supporter of C. S. Parnell. In August he delivered a speech on the Land League at Kildare which was characterized as "wicked and cowardly" by W. E. Forster; he advocated boycotting, and was arrested in May 1881 under the Coercion Act, and again after two months of freedom in October. In 1883 he resigned his seat for reasons of health, but was returned unopposed in 1885 for East Mayo, which he continued to represent. He was one of the prime movers in the famous "plan of campaign," which provided that the tenant should pay his rent to the National League instead of the landlord, and in case of eviction be supported by the general fund. Mr Dillon was compelled by the court of queen's bench on the 14th of December 1886 to find securities for good behaviour, but two days later he was arrested while receiving rents on Lord Clanricarde's estates. In this instance the jury disagreed, but in June 1888 under the provisions of the new Criminal Law Procedure Bill he was condemned to six months' imprisonment. He was, however, released in September, and in the spring of 1889 sailed for Australia and New Zealand, where he collected funds for the Nationalist party. On his return to Ireland he was again arrested, but, being allowed bail, sailed to America, and failed to appear at the trial. He returned to Ireland by way of Boulogne, where he and Mr W. O'Brien held long and indecisive conferences with Parnell. They surrendered to the police in February, and on their release from Galway gaol in July declared their opposition to Parnell. After the expulsion of Mr T. M. Healy and others from the Irish National Federation, Mr Dillon became the chairman (February 1896). His early friendship with Mr O'Brien gave place to considerable hostility, but the various sections of the party were ostensibly reconciled in 1900 under the leadership of Mr Redmond. In the autumn of 1896 he arranged a convention of the Irish race, which included 2000 delegates from various parts of the world. In 1897 Mr Dillon opposed in the House the Address to Queen Victoria on the occasion of the Diamond Jubilee, on the ground that her reign had not been a blessing to Ireland, and he showed the same uncompromising attitude in 1901 when a grant to Lord Roberts was under discussion, accusing him of "systematized inhumanity." He was suspended on the 20th of March for violent language addressed to Mr Chamberlain. He married in 1895 Elizabeth (d. 1907), daughter of Lord justice J. C. Mathew.

DILUVIUM (Lat. for "deluge," from _diluere_, to wash away), a term in geology for superficial deposits formed by flood-like operations of water, and so contrasted with alluvium (q.v.) or alluvial deposits formed by slow and steady aqueous agencies. The term was formerly given to the "boulder clay" deposits, supposed to have been caused by the Noachian deluge.

DIME (from the Lat. _decima_, a tenth, through the O. Fr. _disme_), the tenth part, the tithe paid as church dues, or as tribute to a temporal power. In this sense it is obsolete, but is found in Wycliffe's translation of the Bible--"He gave him dymes of alle thingis" (Gen. xiv. 20). A dime is a silver coin of the United States, in value 10 cents (English equivalent about 5d.) or one-tenth of a dollar; hence "dime-novel," a cheap sensational novel, a "penny dreadful"; also "dime-museum."

DIMENSION (from Lat. _dimensio_, a measuring), in geometry, a magnitude measured in a specified direction, i.e. length, breadth and thickness; thus a line has only length and is said to be of one dimension, a surface has length and breadth, and has two dimensions, a solid has length, breadth and thickness, and has three dimensions. This concept is extended to algebra: since a line, surface and solid are represented by linear, quadratic and cubic equations, and are of one, two and three dimensions; a biquadratic equation has its highest terms of four dimensions, and, in general, an equation in any number of variables which has the greatest sum of the indices of any term equal to n is said to have n dimensions. The "fourth dimension" is a type of non-Euclidean geometry, in which it is conceived that a "solid" has one dimension more than the solids of experience. For the dimensions of units see UNITS, DIMENSIONS OF.

DIMITY, derived from the Gr. [Greek: dimitos] "double thread," through the Ital. _dimito_, "a kind of course linzie-wolzie" (Florio, 1611); a cloth commonly employed for bed upholstery and curtains, and usually white, though sometimes a pattern is printed on it in colours. It is stout in texture, and woven in raised patterns.

DINAJPUR, a town (with a population in 1901 of 13,430) and district of British India, in the Rajshahi division of Eastern Bengal and Assam. The earthquake of the 12th of June 1897 caused serious damage to most of the public buildings of the town. There is a railway station and a government high school. The district comprises an area of 3946 sq. m. It is traversed in every direction by a network of channels and water courses. Along the banks of the Kulik river, the undulating ridges and long lines of mango-trees give the landscape a beauty which is not found elsewhere. Dinajpur forms part of the rich arable tract lying between the Ganges and the southern slopes of the Himalayas. Although essentially a fluvial district, it does not possess any river navigable throughout the year by boats of 4 tons burden. Rice forms the staple agricultural product. The climate of the district, although cooler than that of Calcutta, is very unhealthy, and the people have a sickly appearance. The worst part of the year is at the close of the rains in September and October, during which months few of the natives escape fever. The average maximum temperature is 92.3° F., and the minimum 74.8°. The average rainfall is 85.54 in. In 1901 the population was 1,567,080, showing an increase of 6% in the decade. The district is partly traversed by the main line of the Eastern Bengal railway and by two branch lines. Save between 1404 and 1442, when it was the seat of an independent _raj_, founded by Raja Ganesh, a Hindu turned Mussulman, Dinajpur has no separate history. Pillars and copper-plate inscriptions have yielded numerous records of the Pal kings who ruled the country from the 9th century onwards, and the district is famous for many other antiquities, some of which are connected by legend with an immemorial past (see _Reports, Arch. Survey of India_, xv.; _Epigraphia Indica_, ii.).

DINAN, a town of north-western France, capital of an arrondissement in the department of Côtes-du-Nord, 37 m. E. of St Brieuc on the Western railway. Pop. (1906) 8588. Dinan is situated on a height on the left bank of the Ranee (here canalized), some 17 m. above its mouth at St Malo, with which it communicates by means of small steamers. It is united to the village of Lanvallay on the right bank of the river by a granite viaduct 130 ft. in height. The town is almost entirely encircled by the ramparts of the middle ages, strengthened at intervals by towers and defended on the south by a castle of the late 14th century, which now serves as prison. Three old gateways are also preserved. Dinan has two interesting churches; that of St Malo, of late Gothic architecture, and St Sauveur, in which the Romanesque and Gothic styles are intermingled. In the latter church a granite monument contains the heart of Bertrand Du Guesclin, whose connexion with the town is also commemorated by an equestrian statue. The quaint winding streets of Dinan are often bordered by medieval houses. Its picturesqueness attracts large numbers of visitors and there are many English residents in the town and its vicinity. About three-quarters of a mile from the town are the ruins of the château and the Benedictine abbey at Léhon; near the neighbouring village of St Esprit stands the large lunatic asylum of Les Bas Foins, founded in 1836; and at no great distance is the now dismantled château of La Garaye, which was rendered famous in the 18th century by the philanthropic devotion of the count and countess whose story is told in Mrs Norton's _Lady of La Garaye_. Dinan is the seat of a subprefect and has a tribunal of first instance, and a communal college. There is trade in grain, cider, wax, butter and other agricultural products. The industries include the manufacture of leather, farm-implements and canvas.

The principal event in the history of Dinan, which was a stronghold of the dukes of Brittany, is the siege by the English under the duke of Lancaster in 1359, during which Du Guesclin and an English knight called Thomas of Canterbury engaged in single combat.

DINANT, an ancient town on the right bank of the Meuse in the province of Namur, Belgium, connected by a bridge with the left bank, on which are the station and the suburb of St Medard. Pop. (1904) 7674. The name is supposed to be derived from Diana, and as early as the 7th century it was named as one of the dependencies of the bishopric of Tongres. In the 10th century it passed under the titular sway of Liége, and remained the fief of the prince-bishopric till the French revolution put an end to that survival of feudalism. In the middle of the 15th century Dinant reached the height of its prosperity. With a population of 60,000, and 8000 workers in copper, it was one of the most flourishing cities in Walloon Belgium, until it incurred the wrath of Charles the Bold. Belief in the strength of its walls and of the castle that occupied the centre bridge, thus effectually commanding navigation by the river, engendered arrogance and overconfidence, and the people of Dinant thought they could defy the full power of Burgundy. Perhaps they also expected aid from France or Liége. In 1466 Charles, in his father's name, laid siege to Dinant, and on the 27th of August carried the place by storm. He razed the walls and allowed the women, children and priests to retire in safety to Liége, but the male prisoners he either hanged or drowned in the river by causing them to be cast from the projecting cliff of Bouvignes. In 1675 the capture of Dinant formed one of the early military achievements of Louis XIV., and it remained in the hands of the French for nearly thirty years after that date. The citadel on the cliff, 300 ft. or 408 steps above the town, was fortified by the Dutch in 1818. It is now dismantled, but forms the chief curiosity of the place. The views of the river valley from this eminence are exceedingly fine. Half way up the cliff, but some distance south of the citadel, is the grotto of Montfat, alleged to be the site of Diana's shrine. The church of Notre Dame, dating from the 13th century, stands immediately under the citadel and flanking the bridge. It has been restored, and is considered by some authorities, although others make the same claim on behalf of Huy, the most complete specimen in Belgium of pointed Gothic architecture. The baptismal fonts date from the 12th century, and the curious spire in the form of an elongated pumpkin and covered with slates gives a fantastic and original appearance to the whole edifice. The present prosperity of Dinant is chiefly derived from its being a favourite summer resort for Belgians as well as foreigners. It has facilities for beating and bathing as well as for trips by steamer up and down the river Meuse. It is also a convenient central point for excursions into the Ardennes. Although there are some indications of increased industrial activity in recent years, the population of Dinant is not one-eighth of what it was at the time of the Burgundians.

DINAPUR, a town and military station of British India, in the Patna district of Bengal, on the right bank of the Ganges, 12 m. W. of Patna city by rail. Pop. (1901) 33,699. It is the largest military cantonment in Bengal, with accommodation for two batteries of artillery, a European and a native infantry regiment. In 1857 the sepoy garrison of the place initiated the mutiny of that year in Patna district, but after a conflict with the European troops were forced to retire from the town, and subsequently laid siege to Arrah.

DINARCHUS, last of the "ten" Attic orators, son of Sostratus (or, according to Suidas, Socrates), born at Corinth about 361 B.C. He settled at Athens early in life, and when not more than twenty-five was already active as a writer of speeches for the law courts. As an alien, he was unable to take part in the debates. He had been the pupil both of Theophrastus and of Demetrius Phalereus, and had early acquired a certain fluency and versatility of style. In 324 the Areopagus, after inquiry, reported that nine men had taken bribes from Harpalus, the fugitive treasurer of Alexander. Ten public prosecutors were appointed. Dinarchus wrote, for one or more of these prosecutors, the three speeches which are still extant--_Against Demosthenes_, _Against Aristogeiton_, _Against Philocles_. The sympathies of Dinarchus were in favour of an Athenian oligarchy under Macedonian control; but it should be remembered that he was not an Athenian citizen. Aeschines and Demades had no such excuse. In the Harpalus affair, Demosthenes was doubtless innocent, and so, probably, were others of the accused. Yet Hypereides, the most fiery of the patriots, was on the same side as Dinarchus.

Under the regency of his old master, Demetrius Phalereus, Dinarchus exercised much political influence. The years 317-307 were the most prosperous of his life. On the fall of Demetrius Phalereus and the restoration of the democracy by Demetrius Poliorcetes, Dinarchus was condemned to death and withdrew into exile at Chalcis in Euboea. About 292, thanks to his friend Theophrastus, he was able to return to Attica, and took up his abode in the country with a former associate, Proxenus. He afterwards brought an action against Proxenus on the ground that he had robbed him of some money and plate. Dinarchus died at Athens about 291.

According to Suidas, Dinarchus wrote 160 speeches; and Dionysius held that, out of 85 extant speeches bearing his name, 58 were genuine,--28 relating to public, 30 to private causes. Although the authenticity of the three speeches mentioned above is generally admitted, Demetrius of Magnesia doubted that of the speech Against Demosthenes, while A. Westermann rejected all three. Dinarchus had little individual style and imitated by turns Lysias, Hypereides and Demosthenes. He is called by Hermogenes [Greek: o critinos Demosthenes], a metaphor taken from barley compared with wheat, or beer compared with wine,--a Demosthenes whose strength is rougher, without flavour or sparkle.
