Part 10

After all, the real fun of science begins when one finds out something that was not known before. This is what is rather pompously called original research. It is interesting to see in my father's life how the sporting instinct gave way to the love of discovery. To show this passionate love of sport, he mentions that when as a boy he had just shot his first snipe, his hands trembled so that he could hardly reload his gun. Yet the same boy on the voyage of the _Beagle_ found out how much more entrancing than shooting was the chase of new facts and new theories, and he handed over his gun to his servant. And something of this delight one may have as the merest learner. You are not likely to find out things that nobody knew before, but you may easily find out things quite new to yourself--which to you personally are as good as the brand-newest discovery. Lastly, there is another excellent reason for scientific work, namely, that the bodily welfare of the human race and of its friendly animals and plants depends on accurate knowledge of the nature and behaviour of everything in the world. It is this truth that makes us believe that every fact has its value. Its value may remain unrecognised for long periods, and then it may suddenly find its place in the great jig-saw puzzle of knowledge. The two most exciting sciences just now seem to me to be Physics and Pathology; one as bringing us nearer to the knowledge of the structure of matter, the other in disentangling the causes of deadly and mysterious diseases such as malaria, diphtheria, hydrophobia, sleeping sickness, in a manner and with a success hitherto undreamt of. But because the advances in these sciences are so brilliant and hopeful, no civilised worker will venture to despise the pursuits of less fortunate people whose work seems rather humdrum. There are botanists who spend their whole lives in describing and classifying dried plants in a herbarium. But these are really doing highly valuable work, for the simple reason that we cannot make any accurate use of plants until they have names. I am omitting the purely commercial use of such work, which is very great. I only want to insist that the mere naming of living things is an indispensable stone in the building of the palace of science. All who work at science may recognise that they belong to a guild which makes for the happiness of the human race. And this they must do, not with any pride, but humbly acknowledging how small is their personal share in the total of progress.

The Darwin Buildings, that is to say, the three new laboratories which are open to-day, were absolutely needed to carry out the Head Master's plan of giving every boy in the School a chance of learning science. When I say that at the present time 270 boys under five masters are at work in the laboratories, you will realise to what good use they are being put. As I happen to represent the Royal Society on your Governing Body it is especially satisfactory to me to know that science is here taught on the principle expressed by the motto of the Society: "Nullius in verba," that is to say, not in other people's words, but in your own observation lies the path of Science.

X SIR GEORGE DARWIN {152a}

George Howard, the fifth {152b} child of Charles and Emma Darwin, was born at Down, July 9th, 1845. Why he was christened {152c} George, I cannot say. It was one of the facts on which we founded a theory that our parents lost their presence of mind at the font, and gave us names for which there was neither the excuse of tradition nor of preference on their own part. His second name, however, commemorates his great-grandmother, Mary Howard, the first wife of Erasmus Darwin. It seems possible that George's ill-health and that of his father were inherited from the Howards. This, at any rate, was Francis Galton's view, who held that his own excellent health was a heritage from Erasmus Darwin's second wife. George's second name, Howard, has a certain appropriateness in his case, for he was the genealogist and herald of our family, and it is through Mary Howard that the Darwins can, by an excessively devious route, claim descent from certain eminent people, _e.g._ John of Gaunt. This is shown in the pedigrees which George wrote out, and in the elaborate genealogical tree published in Professor's Pearson's _Life of Francis Galton_. George's parents had moved to Down in September 1842, and he was born to those quiet surroundings of which Charles Darwin wrote, "My life goes on like clockwork, and I am fixed on the spot where I shall end it." It would have been difficult to find a more retired place so near London. In 1842 a coach drive of some twenty miles was the only means of access to Down; and even now that railways have crept closer to it, it is singularly out of the world, with little to suggest the neighbourhood of London, unless it be the dull haze of smoke that sometimes clouds the sky. In 1842 such a village, communicating with the main lines of traffic only by stony tortuous lanes, may well have been enabled to retain something of its primitive character. Nor is it hard to believe in the smugglers and their strings of pack-horses making their way up from the lawless old villages of the Weald, of which the memory then still lingered. {153}

George retained throughout life his deep love for Down. For the lawn with its bright strip of flowers, and for the row of big lime trees that bordered it; for the two yew trees between which we children had our swing, and for many another characteristic which had become as dear and as familiar to him as a human face. He retained his youthful love of the "Sand-walk," a little wood far enough from the house to have for us a romantic character of its own.

George loved the country round Down, and all its dry chalky valleys of ploughed land, with "shaws," _i.e._ broad straggling hedges on their crests, bordered by strips of flowery turf. The country is traversed by many foot-paths; these George knew well and used skilfully in our walks, in which he was generally the leader. His love for the house and the neighbourhood was, I think, entangled with his deepest feelings. In later years his children came with their parents to Down, and they vividly remember his excited happiness, and how he enjoyed showing them his ancient haunts.

In this retired region Charles Darwin's children led a singularly quiet life, practically without friends, and dependent on their brothers and sisters for companionship. George's earliest recollection was of drumming with his spoon and fork on the nursery table because dinner was late, while a barrel-organ played outside. Other memories were less personal; for instance, the firing of guns when Sebastopol was supposed to have been taken. His diary of 1852 shows a composite interest in current events and in the picturesqueness of Natural History: "The Duke is dead. Dodos are out of the world."

He perhaps carried rather far the good habit of re-reading one's favourite authors. He told his children that for a year or so he read through every day the story of Jack the Giant Killer, in a little chap-book with coloured pictures. He early showed signs of the energy which marked his character in later life. I am glad to remember that I became his companion and willing slave. There was much playing at soldiers, and I have a clear remembrance of our marching with toy guns and knapsacks across the field to the Sand-walk. There we made our bivouac with gingerbread, and milk warmed (and generally smoked) over a "touch-wood" fire. I was a private while George was a sergeant, and it was part of my duty to stand sentry at the far end of the kitchen-garden until released by a bugle-call from the lawn. I have a vague remembrance of presenting my fixed bayonet at my father to ward off a kiss, which seemed to me inconsistent with my military duties. Our imaginary names and heights were written up on the wall of the cloak-room. George, with romantic exactitude, made a small foot rule of such a size that he could conscientiously record his height as 6 feet, and mine as slightly less, in accordance with my age and station.

Under my father's instruction George made spears with weighted heads, which he hurled with remarkable skill by means of an Australian throwing stick. I used to skulk behind the big lime trees on the lawn in the character of victim, and I still remember the look of the spear flying through the air with a certain venomous waggle. Indoors, too, we threw at each other wooden javelins, which we received on beautiful shields made by the village carpenter and decorated with coats of arms.

Heraldry was a serious pursuit of his for many years, and the London Library copies of Guillim and Edmonson {156} were generally at Down. He retained a love of the science through life, and his copy of Percy's _Reliques_ is decorated with coats of arms admirably drawn and painted. In later life he showed a power of neat and accurate draughtsmanship, and some of the illustrations in his father's books, _e.g._ in _Climbing Plants_, are by his hand.

His early education was given by governesses, but the boys of the family used to ride twice or thrice a week to be instructed in Latin by Mr. Reed, the Rector of Hayes--the kindest of teachers. For myself, I chiefly remember the cake we used to have at 11 o'clock, and the occasional diversion of looking at the pictures in the great Dutch Bible. George must have impressed his parents with his solidity and self-reliance, since he was more than once allowed to undertake alone the 20-mile ride to the house of a relative at Hartfield in Sussex. For a boy of ten to bait his pony and order his luncheon at the Edenbridge inn was probably more alarming than the rest of the adventure. There is indeed a touch of David Copperfield in his recollections as preserved in family tradition. The waiter always said, "What will you have for lunch, Sir?" to which he replied, "What is there?" and the waiter said, "Eggs and bacon"; and though he hated bacon more than anything else in the world, he felt obliged to have it.

On August 16th, 1856, George was sent to school. Our elder brother, William, was at Rugby, and his parents felt his long absences from home such an evil that they fixed on the Clapham Grammar School for their younger sons. Besides its nearness to Down, Clapham had the merit of giving more mathematics and science than could then be found in public schools. It was kept by the Rev. Charles Pritchard, {157} a man of strong character, and with a gift for teaching mathematics by which George undoubtedly profited. In, I think, 1861 Pritchard left Clapham and was succeeded by the Rev. Alfred Wrigley, a man of kindly mood but without the force or vigour of Pritchard. As a mathematical instructor I imagine Wrigley was a good drillmaster rather than an inspiring teacher. Under him the place degenerated to some extent; it no longer sent so many boys to the Universities, and became more like a "crammer's" and less like a public school. My own recollections of George at Clapham are coloured by an abiding gratitude for his kindly protection of me as a shrinking and very unhappy "new boy" in 1860.

George records in his diary that in 1863 he tried in vain for a Minor Scholarship at St. John's College, Cambridge, and again failed to get one at Trinity in 1864, though he became a Foundation Scholar in 1866. These facts suggested to me that this capacity as a mathematician was the result of slow growth. I accordingly applied to Lord Moulton, who was kind enough to give me his impressions:

My memories of your brother during his undergraduate career correspond closely to your suggestion that his mathematical power developed somewhat slowly and late. Throughout most, if not the whole, of his undergraduate years he was in the same class as myself and Christie, the ex-Astronomer Royal, at Routh's. {158a} We all recognised him as one who was certain of being high in the Tripos, but he did not display any of that colossal power of work and taking infinite trouble that characterised him afterwards. On the contrary, he treated his work rather jauntily. At that time his health was excellent and he took his studies lightly, so that they did not interfere with his enjoyment of other things. {158b} I remember that as the time of the examination came near I used to tell him that he was unfairly handicapped in being in such robust health and such excellent spirits.

Even when he had taken his degree I do not think he realised his innate mathematical power. . . . It has been a standing wonder to me that he developed the patience for making the laborious numerical calculations on which so much of his most original work was necessarily based. He certainly showed no tendency in that direction during his undergraduate years. Indeed, he told me more than once in later life that he detested arithmetic, and that these calculations were as tedious and painful to him as they would have been to any other man, but that he realised that they must be done, and that it was impossible to train anyone else to do them.

As a Freshman he 'kept' (_i.e._ lived) in A 6, the staircase at the N.W. corner of the New Court, afterwards moving to F 3 in the Old Court, pleasant rooms entered by a spiral staircase on the south side of the Great Gate. Below him, in the ground floor room, now used as the College offices, lived Mr. Colvill, who remained a faithful but rarely seen friend as long as George lived.

Lord Moulton, who, as we have seen, was a fellow pupil of George's at Routh's, was held even as a Freshman to be an assured Senior Wrangler, a prophecy that he easily made good. The second place was held by George, and was a much more glorious position than he had dared to hope for. In those days the examiners read out the list in the Senate House at an early hour, 8 a.m. I think. George remained in bed and sent me to bring the news. I remember charging out through the crowd the moment the magnificent "Darwin of Trinity" had followed the expected "Moulton of St. John's." I have a general impression of a cheerful crowd sitting on George's bed and literally almost smothering him with congratulations. He received the following characteristic letter from his father: {159}

DOWN, _Jan._ 24_th_ [1868].

My dear old fellow,

I am so pleased. I congratulate you with all my heart and soul. I always said from your early days that such energy, perseverance and talent as yours would be sure to succeed: but I never expected such brilliant success as this. Again and again I congratulate you. But you have made my hand tremble so I can hardly write. The telegram came here at eleven. We have written to W. and the boys.

God bless you, my dear old fellow--may your life so continue.

Your affectionate Father, CH. DARWIN.

In those days the Tripos examination was held in the winter, and the successful candidates got their degrees early in the Lent Term. George records in his diary that he took his B.A. on January 25th, 1868; also that he won the second of the two Smith's Prizes--the first being the natural heritage of the Senior Wrangler. There is little to record in this year. He had a pleasant time in the summer, coaching Clement, the nephew of Sir Charles Bunbury, at his beautiful place Barton Hall in Suffolk. In the autumn he was elected a Fellow of Trinity, as he records, "with Galabin, young Niven, Clifford, [Sir Frederick] Pollock, and [Sir Sidney] Colvin." W. K. Clifford was the well-known brilliant mathematician who died comparatively early.

Chief among his Cambridge friends were the brothers Arthur, Gerald, and Frank Balfour. The last-named was killed, aged 31, in a climbing accident in 1882 on the Aiguille Blanche near Courmayeur. He was remarkable both for his scientific work and for his striking and most lovable personality. George's affection for him never faded. His daughter remembers her father (not long before his death) saying with emotion, "I dreamed Frank Balfour was alive." I imagine that tennis was the means of bringing George into contact with Mr. Arthur Balfour. What began in this chance way grew into an enduring friendship, and George's diary shows how much kindness and hospitality he received from Mr. Balfour. George had also the advantage of knowing Lord Rayleigh at Cambridge, and retained his friendship through his life.

In the spring of 1869 he was in Paris for two months working at French. His teacher used to make him write original compositions, and George gained a reputation for humour by giving French versions of all the old Joe Millers and ancient stories he could remember.

It was his intention to make the Bar his profession, {161} and in October 1869 we find him reading with Mr. Tatham, in 1870 and 1872 with the late Mr. Montague Crackenthorpe (then Cookson), and in November 1871 he was a pupil of Mr. W. G. Harrison. The most valued result of his legal work was the friendship of Mr. and Mrs. Crackenthorpe, which he retained throughout his life. During these years we find the first indications of the circumstances which forced him to give up a legal career--namely, his failing health and his growing inclination towards science. {162} Thus in the summer of 1869, when we were all at Caerdeon in the Barmouth valley, he writes that he "fell ill," and again in the winter of 1871. His health deteriorated markedly during 1872 and 1873. In the former year he went to Malvern and to Homburg without deriving any advantage. I have an impression that he did not expect to survive these attacks, but I cannot say at what date he made this forecast of an early death. In January 1873 he visited Cannes, and "came back very ill." It was in the spring of this year that he first consulted Dr. (afterwards Sir Andrew) Clark, from whom he received the kindest care. George suffered from digestive troubles, sickness, and general discomfort and weakness. Dr. Clark's care probably did what was possible to make life more bearable, and as time went on his health gradually improved. In 1894 he consulted the late Dr. Eccles, and by means of the rest-cure, then something of a novelty, his weight increased from 9 stone to 9 stone 11 pounds. I gain the impression that this treatment produced a permanent improvement, although his health remained a serious handicap throughout his life.

Meanwhile he had determined on giving up the Bar, and settled in October 1873, when he was 28 years old, at Trinity in Nevile's Court next the Library (G 4). His diary continues to contain records of ill-health and of various holidays in search of improvement. Thus in 1873 we read, "Very bad during January. Went to Cannes and stayed till the end of April." Again in 1874, "February to July very ill." In spite of unwellness he began in 1872-3 to write on various subjects. He sent to _Macmillan's Magazine_ {163a} an entertaining article, "Development in Dress," where the survivals in modern costume were recorded and discussed from the standpoint of evolution. In 1873 he wrote "On beneficial restriction to liberty of marriage," {163b} a eugenic article for which he was attacked with gross unfairness and bitterness by the late St. George Mivart. He was defended by Huxley; and Charles Darwin formally ceased all intercourse with Mivart. We find mention of a "Globe Paper for the British Association" in 1873. And in the following year he read a contribution on "Probable Error" to the Mathematical Society {163c}--on which he writes in his diary, "found it was old." Besides another paper in the _Messenger of Mathematics_, he reviewed "Whitney on Language," {163d} and wrote a "Defence of Jevons" which I have not been able to trace. In 1875 he was at work on the "Flow of Pitch," on an "Equipotential Tracer," on slide rules, and sent a paper on "Cousin Marriages" to the Statistical Society. {164a} It is not my province to deal with these papers; they are enumerated here as showing his activity of mind and his varied interests,--features in his character which were notable throughout life.

The most interesting entry in his diary for 1875 is a "Paper on Equipotentials much approved by Sir W. Thomson." This is the first notice of an association of primary importance in George's scientific career. Then came his memoir, "On the influence of geological changes in the earth's axis of rotation." Lord Kelvin was one of the referees appointed by the Council of the Royal Society to report on this paper, which was published in the _Philosophical Transactions_ in 1877.

In his diary, November 1878, George records, "Paper on tides ordered to be printed." This refers to his work, "On the bodily tides of viscous and semi-elastic spheroids, etc.," published in the _Phil. Trans._ in 1879. It was in regard to this paper that his father wrote to George on October 29th, 1878: {164b}

My dear old George,

I have been quite delighted with your letter and read it all with eagerness. You were very good to write it. All of us are delighted, for considering what a man Sir William Thomson is, it is most grand that you should have staggered him so quickly, and that he should speak of your 'discovery, etc.' . . . Hurrah for the bowels of the earth and their viscosity, and for the moon and for the Heavenly bodies, and for my son George (F.R.S. very soon). . . . {165a}

The bond of pupil and master between George Darwin and Lord Kelvin, originating in the years 1877-8, was to be a permanent one, and developed, not merely into scientific co-operation, but into a close friendship. Sir Joseph Larmor has recorded {165b} that George's "tribute to Lord Kelvin, to whom he dedicated Volume I of his Collected Papers {165c} . . . gave lively pleasure to his master and colleague." His words were:

Early in my scientific career it was my good fortune to be brought into close personal relationship with Lord Kelvin. Many visits to Glasgow and to Largs have brought me to look up to him as my master, and I cannot find words to express how much I owe to his friendship and to his inspiration.

During these years there is evidence that he continued to enjoy the friendship of Lord Rayleigh and of Mr. Balfour. We find in his diary records of visits to Terling and to Whittingehame, or of luncheons at Mr. Balfour's house in Carlton Gardens, for which George's scientific committee work in London gave frequent opportunity. In the same way there are many records of visits to Francis Galton, with whom he was united alike by kinship and affection.

Few people indeed can have taken more pains to cultivate friendship than did George. This trait was the product of his affectionate and eminently sociable nature, and of his characteristic energy and activity. In earlier life he travelled a good deal in search of health, {166} and in after years he attended numerous congresses as a representative of scientific bodies. He thus had unusual opportunities of making the acquaintance of men of other nationalities, and some of his warmest friendships were with foreigners. In passing through Paris he rarely failed to visit M. and Mme d'Estournelles and "the d'Abbadies." It was in Algiers in 1878 and 1879 that he cemented his friendship with the late J. F. MacLennan, author of _Primitive Marriage_; and in 1880 he was at Davos with the same friends. In 1881 he went to Madeira, where he received much kindness from the Blandy family--doubtless through the recommendation of Lady Kelvin.
