PREFACE Aw attempt has been made in this short biography to bring into prominence Huxley’s scientific work, though much of it was of so specialized a nature as to make a full presentment to other than professed zoologists practically impossible. It has been necessary to incur a large debt to Mr. Leonard Huxley’s admirable Life and Letters of Thomas Henry Huxley, the chief source of information, and this is gratefully acknowledged. Reference has been made to the first edition, in two volumes (1900), the abbreviation “ Life”? being em- ployed. In dealing with the published works, the Memorial Edition of the Scientific Memoirs (Sci. Mem.) and the nine volumes of Collected Essays (Coll.

Tuomas Henry Huxtey was born at Ealing on May 4, 1825, his father, George Huxley, being senior master in the well-known semi-public school of which Dr. Nicholas was then the head. Under the older name of Hodesleia the family can be traced back in Cheshire to the time of Richard I., but there is nothing in its annals foreshadowing the extraordinary eminence attained during the last half of the nineteenth century by its best known representative. So far as our information goes, Huxley was decidedly a “sport”—as he himself described the great Newton—a concrete illustration of the biological fact that variations of large amount may from time to time occur. To the first volume of his Collected Essays, issued in 1893, Huxley prefixed a short Autobiography, originally written for another purpose, in which the bulk of his physical and mental characteristics are ascribed to inheri- tance from his mother. As to the former, he was tall, dark, and rather spare, with a commanding presence, and a striking though not handsome countenance, chiefly remarkable for breadth of forehead, prominence of chin, and a profusion of long straight hair. Huxley’s most salient mental characteristics were absolute sincerity and A 2 THOMAS HENRY HUXLEY straightforwardness, unrivalled powers of criticism and generalization, and an equally remarkable faculty of rapid intuition, of which last he says: “(If my time were to come over again, there is nothing I would less will- ingly part with than my inheritance of mother wit.” To these must be added, as supposed endowments from the paternal side, a sufficiently hot temper, and a vast tenacity of purpose, ‘‘ which unfriendly observers some- times call obstinacy,” but without which he could never have persisted in the upward climb to distinction which in its earlier stages often necessitated—to use his own phrase—‘‘hanging on by the eyelids.” From his father was inherited, too, the artistic power which rendered such signal service to his scientific work, and which made his lightning blackboard sketches during lecture both the despair and delight of his pupils. His artistic faculties also included an intense appreciation of music, which his strenuous life enabled him all too infrequently to gratify, as well as very strong literary tastes. Had Huxley been the eldest child, he might perhaps have become an “‘ infant phenomenon,” but as the seventh, this stunting experience, fortunately for science and the world at large was spared him. His experience of “‘unreformed public school-life,” between the ages of eight and ten, leaves little that is pleasant to record, the memory of a successful fight being the only illuminating spot. In 1835 his father returned to the original home at Coventry, to become manager of a savings bank, and from this time on the boy’s systematic school education seems practically to have come to anend. But this was far more than compensated by his passion for reading, and friendships contracted with older persons. For a boy of twelve to read—and appreciate—Hutton’s Geohgy, EARLY LIFE AND TRAINING 3 the forerunner of Lyell’s Principles, seems sufficiently remarkable, but that he should, a little later, master Hamilton’s Logic, is no less than astounding. To this period we must refer the inception of Huxley’s lifelong interest in philosophy, his ever manifest desire to get behind the facts, to reach bed-rock so far as possible. Asa result of his association with his brother-in-law, Dr. Cooke, he now acquired his first direct interest in anatomy, and, most unfortunately, contracted blood- poisoning at a post-mortem examination, which dates the origin of digestive troubles that severely handicapped his entire career. Among the works read by Huxley during his early teens were several of Carlyle’s, and there can be no doubt that these exerted a profound influence upon his character, strengthening his natural tendency to despise all shams and humbugs, and to entertain high ideals of duty. It would also seem that they were of inestimable service in another respect, leading the young student to commence the study of German, a much neglected lan- guage in those days. He also very early laid the foundation of a thorough knowledge of French and Italian. In later years his linguistic attainments were not only of the greatest ser- vice to him in the prosecution of his researches, but his example has effected a complete metamorphosis in the attitude of serious workers in the natural history sciences. Before Huxley’s time the results of foreign research were often ignored or neglected. He first inaugurated the now universal custom of making bibliographical references and lists as complete as possible, whereby much overlapping and waste of energy have been averted. Many if not most boys in their teens have some idea of what they would like to be, and Huxley was no 4 THOMAS HENRY HUXLEY exception to the rule. We read in his Autobiography as follows :— “ As I grew older my great desire was to be a mechanical engineer, but the fates were against this, and, while very young, I commenced the study of medicine under a medical brother-in- law. . .. Iam not sure that I have not all along been a sort of mechanical engineer in partibus infidelium. ... The only part of my professional course which really and deeply interested me was physiology, which is the mechanical engineering of living machines . . . what I cared for was the architectural and engineering part of the business, i.e., natural history, the working out the wonderful unity of plan in the thousands and thousands of diverse living constructions, and the modifications of similar apparatuses to serve diverse ends’? (Coll. Essays, i, pp. 6-7). In January, 1841, he went to Rotherhithe, and com- menced his medical studies by becoming assistant to Dr. Chandler. He now for the first time came into contact with the very poor, and to this period we may refer the beginning of that marked interest in the working-classes, which afterwards bore fruit in his contributions to schemes for the improvement of elementary education, and in his numerous lectures to working men. Somewhat later on, the young student of medicine was apprenticed to his brother-in-law, J. G. Scott, a doctor in North London, the husband of his eldest and favourite sister Lizzie, and took his first step towards graduation by beginning to prepare for the matriculation examination of London University, attending lectures at Sydenham College. His class successes were consider- able, and included a silver medal for botany, given by the Apothecaries’ Society, the winning of which, he afterwards declared, gave him more pleasure than the award of the Royal Society’s Medal years later. We learn from an old diary kept during these years that in addition to examination studies and the pursuit of Ger- FIRST RESEARCH PAPER 5 man, he read the Physiohgy of the eminent Berlin professor, Johannes Miller, whose epoch-making comparative work in natural history he afterwards continued and extended with such brilliant success. October 1, 1842, was an important date in the life of young Huxley, for, together with his brother James, he began his medical course at Charing Cross Hospital as a Free Scholar. Wharton Jones, the lecturer on physio- logy, undoubtedly made the most marked impression upon him, partly in virtue of his subject, but still more on account of his personality. Huxley’s own opinion of himself as a man and as a student, at this epoch, was sufficiently pessimistic, and we may well allow our- selves to discount it altogether. The feature that most impressed his fellow-students was his extraordinary energy, one result of which was his first contribution to science, in the form of a paper entitled, ‘‘On a Hitherto Undescribed Structure in the Human Hair-sheath,” published in the London Medical Gazette for July 1845 (Sci. Mem., i, 1, p. 1). The structure in question is still known as ‘‘ Huxley’s layer,” and in the paper we find that the German literature is dealt with in character- istic fashion. It is given to but few medical students to make even small additions to the sum of scientific knowledge. He passed through his student’s course with marked distinction, taking a first prize in chemistry, as well as one in anatomy and physiology. For the two latter subjects he was awarded a gold medal, his place being second in honours in the M.B. examination of the University of London, 1845. CHAPTER II EXPERIENCES AS A NAVAL SURGEON ON THE “‘ RATTLESNAKE” [1846-50]. Tue chance suggestion made by Huxley’s fellow- student Fayrer (afterwards Sir Joseph Fayrer) that he should apply for a post in the Medical Service of the Navy, determined his whole future career, and conse- quently had a momentous influence on the progress of scientific thought and research. Early in 1846 he entered the Navy, and was appointed to the Victory, for duty at Haslar Hospital, serving under Sir John Richardson, through whose recommendation he was transferred after some delay to the Rattlesnake frigate during October of the same year, in the capacity of assistant surgeon. It was also understood that he would co-operate with Macgillivray, the naturalist to the expedition. The ship was detailed for survey work in Australian and East Indian waters. During the months that elapsed between the time the appointment was promised him (May) and that of departure (December), young Huxley with unremitting energy took every opportunity of fitting himself for the work of investigation before him. Owen, Gray, and particularly Edward Forbes, gave him much in- formation and counsel which afterwards proved invalu- able. Forbes, a pioneer in the art of dredging for scientific purposes, was especially friendly, sparing no pains in explaining the technical methods employed for the capture of marine animals. From him too Huxley 6 EXPERIENCES AS NAVAL SURGEON 5 obtained a living specimen of thé Lancelet (Amphioxus Janceolatus), for the purpose of investigating the nature of its blood, on which he read a short paper at the Meeting of the British Association, held that year at Southampton (Brit. Assoc. Rep., 1847, Part 2, p. 95. Sci. Mem., i, 1, p. 4). It is interesting to notice that Charles Darwin and Sir Joseph Dalton Hooker, who were afterwards among Huxley’s most intimate friends, began, as he did, their scientific work on board ship, and given sufficient initial ability, there is much to be said for some such way of gaining horizon and wealth of imagination at the outset of a specialist career in natural history. There is at least no question that Huxley’s early experiences in a ship of discovery were an important factor in giving that breadth of knowledge and interest by which he was so eminently characterized. From letters of the period we learn that the young naturalist looked forward to the cruise with the most eager anticipation, and chafed at the delays which inter- vened between the promise of the appointment and the departure of the Rattlesnake. She at last left Spithead on December 3, 1846, and was away for four years, of which nearly three were spent in Australian waters. Professor Virchow in the Huxley Lecture for 1898, summarized the value of the training acquired in the following admirable way :— «« When Huxley himself left Charing Cross Hospital in 1846, he had enjoyed a rich measure of instruction in anatomy and physiology. ‘T’hus trained, he took the post of naval surgeon, and by the time that he returned, four years later, he had become a perfect zoologist anda keen-sighted ethnologist. How this was possible, any one will readily understand who knows from his own experience how great the value of personal observation is for the development of independent and unprejudiced thought. 8 THOMAS HENRY HUXLEY For a young man who, besides collecting a rich treasure of positive knowledge, has practised dissection and the exercise of a critical judgment, a long sea-voyage and a peaceful sojourn among entirely new surroundings afford an invaluable opportunity for original work and deep reflection. Freed from the formalism of the schools, thrown upon the use of his own intellect, compelled to test each single object as regards properties and history, he soon forgets the dogmas of the prevailing system and becomes, first a sceptic, and then an investigator’ (Times, Oct. 4, 1898). Apart from the necessary appliances for marine sur- veying, her chief work, the scientific equipment of the Rattlesnake was nil, nor was she provided with any books of reference. This was only a part of the cheese- paring policy of the then Admiralty, which, as we shall see in the sequel, nearly led to Huxley’s abandoning science as a profession altogether. But this sad lack of equipment only adds to the brilliance of the work effected under such trying and difficult conditions. Regarding the routine details of Huxley’s life on board ship we learn that congenial company largely atoned for inconvenient quarters, and his personal char- acteristics stood him in good stead. Kindly good-nature and equable spirits, combined with a saving sense of humour and entire absence of “side,” will go far to avert friction, even among a band of cooped-up explorers. After touching at Madeira, the Rattlesnake sailed to Rio de Janeiro, where dredging for marine animals began. Thence vid the Cape and Mauritius to Hobart Town and Sydney, the last being reached on July 16, 1847. Besides a paper on a rare bivalve mollusc of ancient type," the scientific first fruits of the voyage were in the form of two memoirs, one on the “« Anatomy of 1 © Description of the Animal of Trigonia, from Actual Dissection” (Proc. Zool. Soc., xvii, 1849; and Annals and Mag. Nat. Hist., v, 1850, Sci. Mem., i, 11, p. 6). EARLY RESEARCHES 9 Physalia,”! the Portuguese man-of-war, a colonial jelly- fish (Proc. Linn. Soc., 1849), and the other ‘On the Anatomy and the Affinities of the Family of the Medusz” (Phil. Trans. Roy. Soc., 1849, Part 2, p. 413. Sci. Mem., i, Iv, p. 9). Several other memoirs? may be grouped with these, as well as the classical monograph on “ The Oceanic Hydrozoa” (Ray Society, 1858), of which the publication was long delayed, owing to the penuri- ousness of the Government. These publications deal with those lower organisms’ known to the older naturalists as ‘« Zoophytes,” and now technically named Ccelentera. They include hydroid zoophytes, meduse or jelly-fishes, sea-anemones, corals, and various other forms. Until Huxley’s time the systematics of this vast assemblage of apparently diverse types was in a state of the utmost chaos, the attention of previous workers having been chiefly devoted to description and naming of species without due compari- son. The young navy surgeon reduced this chaos to order, and proved that a common plan of structure dominates the entire series. He demonstrated, in short, that the body of any one of these animals essentially consists of two cellular membranes, bounding variously shaped cavities, and suggested the equivalence of the said membranes to ‘the two primary germinal leaf- lets in the vertebrate embryo” (Prof. G. J. Allman, Life, I; Pe fo): « Brief notice only. The complete “Memoir on Physalia,” op. cit., ii, 1855, pp. 3-5. Sci.

Mem.,, i, xiv, p. 122). fe) THOMAS HENRY HUXLEY These important generalizations constitute a firm foundation on which Haeckel and many other subsequent workers have built, and they in themselves are amply sufficient to give their author a prominent place in any philosophical history of zoology. And when we remember that Huxley’s scientific memoirs, published from 1845 to 1888 (inclusive), amount to no less than 170, ranging over the entire animal kingdom as well as including valuable ethnological work, and that many of them are of epoch-making char- acter and will ever remain classical, our conceptions as to the vast industry and capacity of the man must be almost indefinitely enlarged. In later years Huxley was so prominently before the public as a hard-hitting controversialist, especially on behalf of Darwinism and the higher criticism, possessed of unrivalled sardonic humour, that many are apt to regard him as of a somewhat unsympathetic nature. Such an idea, however, is entirely devoid of any solid foundation, for like so many independent and positive characters, he was extremely sensitive to the sympathy of others, and was himself warm-hearted and appreciative to a degree. It is somewhat unfortunate that a number of his pungent epigrams, thrown off in moments of irritation or as flashes of irrepressible sarcastic wit without thought of their perpetuation, have been pre- served to give a totally wrong impression of his general character. As for the advancement of science, so also for Huxley’s private life, the voyage of the Rattlesnake proved to be of no small importance. For in Sydney he met, and became engaged to, his future wife, Miss Henrietta Anne Heathorn, his ideal union with whom was destined to endure for forty years. The eleven months spent from EARLY RESEARCHES II first to last in Sydney afforded abundant opportunity for intimate mutual knowledge. Apart from a short visit made to Bass’s Strait, the Rattlesnake made three northern cruises, surveying the inshore Passage (between Australia and the Great Barrier Reef), and thence exploring Torres Straits, the Louisiade Archipelago and S.E. New Guinea. A westward ex- tension of this work in the direction of Java and Sumatra was prevented by the premature death of the commander, Captain Owen Stanley. The ship finally left Australia for England in May, 1850, returning by way of the Falk- lands and Azores to Plymouth, and arriving at Chatham on November 9, of the same year. In a letter to Sir John Richardson, dated October 31, 1850, Huxley summarizes his Rattlesnake work (Life, i, pp- 57-8), and the information there given is supple- mented by his paper, ‘‘ Zoological Notes and Observa- tions made on board H.M.S. Rattlesnake during the years 1846-50” (Annals and Mag. Nat. Hist., Ser. 2, vii, 1851, pp- 304-6, and viii, 1851, pp. 433-42. Sci. Mem., i, 1x, p. 80). Apart from the paper on Trigonia and the re- searches on Medusz already mentioned, they include the following, of which the three first are embodied in the “Notes” just mentioned. 1. ‘Upon Thalassicola,” an undescribed type of the Protozoa or simple unicellular animals, most of which are microscopic. In the middle of last century zoo- logical classification was dominated by the views of Cuvier, who had established several large groups or sub- kingdoms, of which one was known as the “ Radiata.” This included a vast assemblage of heterogeneous forms, among which were Medusz and their allies, Echinoderms (star-fishes, etc.), Entozoa (parasitic worms), Ascidians (sea-squirts), Bryozoa (moss-polypes), and the above-named 12 THOMAS HENRY HUXLEY Protozoa, with which the sponges were then associated. One of Huxley’s aims was to reduce the Radiata to order, breaking it up into smaller natural groups, and determin- ing their affinities so far as possible. His papers on Meduse had succeeded in doing this for one large set of forms, and the paper now under discussion was not merely a description of a new animal, but also a successful attempt to define and delimit the Protozoa. Huxley’s view, now (if sponges are ex- cluded) universally accepted, that these are of relatively simple structure, directly traversed the authority of the celebrated Ehrenberg, already challenged by a number of distinguished naturalists. 2. “On the Anatomy of the Genus Tethya” (a sponge). 3. “On the Auditory Organs in the Crustacea.” The much-vexed question as to the position of these structures (to which another function is now ascribed) in the higher Crustacea, such as prawns and the like, is definitely settled in this paper. 4. ‘¢ Observations sur la Circulation du Sang chez les Mollusques, des Genres Firole et Atlante” (Ann. des Sci. Nat., xiv, 1850, pp. 193-5. Sci. Mem., i, vi, p. 36). —Here we have a positive contribution to the physiology of certain pelagic snails, founded upon observations made on living specimens. Even at the present day physio- logical work on invertebrates is relatively scanty, and that so young a naturalist as Huxley then was should devote some time to it is one of many proofs of the wide nature of his interests. 5. ‘Observations on the Genus Sagitta” (Brit. Assoc. Rep., 1851. Sci. Mem., i, x, p. 96).—The little arrow- worms (Sagitta, etc.) occur in vast numbers in the float- ing population (plankton) of the sea, and their classifi- catory position is still a moot point. In this short paper EARLY RESEARCHES 13 Huxley is inclined to associate them either with certain degenerate Crustacea, or with the Arachnida (scorpions, spiders, etc.), rather inclining to the latter view. But in his letter to Sir John Richardson he tentatively speaks of them as Annelids, or segmented worms. 6. “Observations upon the Anatomy and Physiology of Salpa and Pyrosoma” (Phil. Trans. Roy. Soc., 1851, Part 2, pp. 567-94. Annals and Mag. Nat. Hist., ix, 1852, pp. 242-4. Sci. Mem. i, vm, p. 38). 7. “ Remarks upon Appendicularia and Doliolum, two Genera of the Tunicata” (Phil. Trans. Roy. Soc., 1851, Part 2, pp. 595-606. Sci. Mem., i, vit, p. 69). The last two important memoirs deal with pelagic members of the Tunicata, Ascidians, or sea-squirts, animals which are now known to constitute a lowly group of the Vertebrata. Huxley largely added to our knowledge of their anatomy and physiology, and it does not detract from the merits of his work that parts of it had been anticipated. As in so many of his contribu- tions to science the comparative method of Johannes Miiller was applied with eminent success, and the work on Salpa was of especial interest. For earlier in the century Chamisso discovered in these creatures what he termed “alternation of generations,” i.e., the alternation of a sexual and an asexual stage in the same life-history, a phenomenon which is now known to be of frequent occurrence among plants and in several groups of animals. Huxley succeeded in placing Chamisso’s conclusions on a firm basis, at the same time modifying and extending them. While the memoirs now briefly dealt with, and some others to be subsequently mentioned, were the direct result of Huxley’s voyage, the material collected and the observations then made led to other and later contribu- tions to science. 14 THOMAS HENRY HUXLEY In attempting to estimate the value of the earlier contributions to science it is of course necessary to bear in mind the backward state of many departments of natural history, and the relatively crude nature of biological technique compared with its present condition, especially as regards microscopes, section-cutting and the like. CHAPTER III SUCCESSES AND FAILURE [1850-4]. From the return of the Rattlesnake till 1854 Huxley’s career was scientifically a brilliant success, but other- wise a long series of disappointments, not unmixed with family sorrow. In 1849 the Admiralty had promised him either rapid promotion or financial aid in the publi- cation of his scientific work, but neither promise was redeemed. In spite of the backing of many influential friends, including Sir John Richardson, Prof. Owen and Prof. Edward Forbes, the concessions granted him practically amounted to leave of absence for three years and a half, these being largely spent in working out his results, as embodied in the memoirs dealt with in the last chapter, and in preparation of the monograph on «© The Oceanic Hydrozoa,” to publish which the Govern- ment Grant was needed. The matter came to a head when he applied for a further extension of leave in January 1854, the answer to which was an order to join the J/ustrious at Ports- mouth. Failing to comply with this, he was finally struck off the Navy List in the following March. Not only did he fail in getting the promised aid for publica- tion from the Admiralty, but, for purely technical reasons, the Royal Society was unable to allot him a portion of the annual Government Research Grant for this end. During these years Huxley was also unsuccessful in applications successively made for chairs in Toronto, 15 16 THOMAS HENRY HUXLEY Aberdeen, Cork, and King’s College, London. And in the middle of this depressing period the death of his mother, which took place in April 1852, overwhelmed him with the most profound sorrow. At this time he was sorely tempted to abandon science as a profession altogether, and but for the encouragement of his sister Lizzie and the unwavering trust and devotion of Miss Heathorn, might perhaps have done so. Huxley’s many occasions for despondency began to be augmented in 1852 by professional jealousies, and by attempts, luckily unsuccessful, to retard his further progress. Then, as always, he proved himself a per- fectly straightforward antagonist, but at the same time one whom it was decidedly unpleasant to tackle. There is fortunately a reverse side to the picture, constituted by the immediate result of his scientific work, and the friendships contracted during this some- what depressing period of his life. His memoirs on the Medusz and their allies, published during his absence from England, placed him at once in the foremost rank of scientific workers, and on June 5, 1851, he was elected a Fellow of the Royal Society, being one of fifteen selected from a list of thirty-eight candidates, no small distinction for a young man but just turned twenty- six. And this was the result of sheer merit, untainted by the slightest intrigue. The distinction was very nearly increased by the award of the Royal Medal, which, however, went to the veteran naturalist, New- port, whose work was more voluminous but not of better quality. Though naturally proud and pleased at such recognition, it would seem that Huxley’s pleasure was somewhat tempered by reflections as to the dearth of scientific posts in Britain, and the comparatively un- remunerative nature of such as existed, FURTHER RESEARCHES 17 The unsatisfactory attitude of the Admiralty, and un- certainty as to prospects in general, stimulated rather than diminished the output of scientific work at this time. The memoir on Medusz (which gained him the F.R.S.), and the account of Trigonia, were published during the cruise of the Rattlesnake. By the end of 1851 the papers mentioned in the last chapter were completed, and also the following :— I. ‘*Report upon the Researches of Prof. Miiller into the Anatomy and Development of the Echinoderms” (Annals and Mag. Nat. Hist., Ser. 2, viii, 1851, pp. I-19. Sci. Mem., i, x1, p. 103).—After summarizing seven memoirs written by Miller (1846-51), Huxley en- deavours to show that the animals under discussion (star-fishes, sea-urchins, etc.) furnish an illustration of ‘‘alternation of generations,” and discussed the meaning to be attached in zoology to the term ‘ individual,” defining it as ‘the total result of the development of a single ovum, whether this total result consist of one or many independent existences.” Here, as in so many other instances, his strong interest in the philosophical side of natural history is shown in a striking manner. 2. “On Lacinularia socialis, a Contribution to the Anatomy and Physiology of the Rotifera” (Trans. Micros. Soc. London, New Ser., i, 1853, pp. I-19. Read Dec. 31, 1851. Sci. Mem., i, xv, p. 126). This memoir gives an exhaustive account of a wheel- animalcule common in the Medway, and compares it with other members of the group, the affinities of which are discussed. That the Rotifera must be re- moved from the Radiata is clearly proved, but the view that they should be closely associated with Echinoderms, was subsequently modified. ‘To this day the real affinities of wheel-animalcules remain a matter of doubt. B 18 THOMAS HENRY HUALEY Huxley had already commenced his long friendship with Hooker, and that with Tyndall began in connection with the British Association Meeting of 1851, held at Ipswich. His close intimacy with these two fellow- workers had no small influence upon his career, and meant very much in many crises of his after life. To the lay public, «‘ Huxley and Tyndall” long stood for science at large, as well as for scientific heterodoxy. The following scientific memoirs appeared in 1852 :— 1. Onthe Anatomy and Development of Echinococcus veterinorum” (Proc. Zool. Soc., xx, 1852, pp. I 10-26. Sci. Mem., i, xIx, p. 197).—This is an important contri- bution to the morphology of yet another animal group, the tape-worms (Cestoda), part of the heterogeneous assemblage of parasitic forms, which, under the name of Entozoa, were included in the Radiata. Huxley minutely described the tape-worm stage known as Echinococcus, which is found as a large compound cyst in the liver of various hoofed mammals (and at times in man), and com- pared it with the simpler cysts of other tape-worms. His work and that of Von Siebold’s (quoted in this paper) established beyond question that the cyst in question is an earlier stage in the life-history of a tape-worm which infests the intestine of the dog. 2. ‘‘ Researches into the Structure of the Ascidians” (Brit. Assoc. Rep., 1852, pp. 76-7. Sci. Mem., i, xv11I, p- 194).—Huxley’s previous researches upon Ascidians (Tunicates) had given him a unique knowledge of the group, and this short communication embodies various con- clusions arrived at when cataloguing the British Museum collection. It is particularly noteworthy that he com- pares the branchial sac of Ascidians with the perforated pharynx of the Lancelet (Amphioxus), for this foreshadows the brilliant discovery subsequently made by Kowalewsky FURTHER RESEARCHES 19 that Ascidians are not invertebrates but members of the great sub-kingdom of back-boned animals. He also confirms previous statements that the “test” or firm investment which characterizes members of the group contains cellulose, a substance once thought to be peculiar to plants, and of which cotton may be taken as a good example. 3. “On the Morphology of the Cephalous Mollusca, as illustrated by the Anatomy of certain Heteropoda and Pteropoda collected during the voyage of H.M.S. Rattk- snake in 1846-50” (Phil. Trans. Roy. Soc., cxliii, 18 53> pp. 29-66. Read at the Brit. Assoc. Meeting of 1852. Sci. Mem., i, xvir, p. 152).—The ‘“cephalous” Mollusca are those which possess a distinct head, e.g., cuttle-fishes and snails, and the groups named include pelagic animals belonging to the latter category. After remarking on the unsatisfactory state of knowledge as regards Mollusca, the author says that this appears,— “to result from two causes ;—first, from the want of a clear and definite conception of the fundamental varieties of molluscous structure, and of the nature of the changes in the relations of parts which constitute those varieties; and secondly, from the want of a due regard to the facts presented by the development of the various families, which must stand in the relation of cause to the varieties of form. «¢ Now in order to the former end (the obtaining of a definite conception of the varieties of molluscous form), I propose to set forth the structure of certain Heteropoda and Pteropoda ; pelagic animals so transparent, that a perfect knowledge of the arrange- ment of their parts may be arrived at by simple inspection, with- out so much as interrupting a beat of their heart. «‘ Afterwards, I shall inquire how far the known laws of development account for these forms, and thence of what arche- typal form they may be supposed to be modifications.” Many additions to our knowledge were made in the descriptive part of this memoir, though the mistaken 20 THOMAS HENRY HUXLEY account of the mode of action of the rasping-organ (odon- tophore) has been taken over implicitly by many subse- quent observers. But the theoretical matter is of much greater interest, endeavouring as it does to explain various molluscan forms as variants of the same primitive type, which is reconstructed in detail. The particular molluscs employed as the basis of the work were some- what unfortunately chosen, while the Tunicates and Bryozoa (moss-polypes) are too closely associated with the Mollusca, but though some of the conclusions reached would not now be accepted, the memoir will always re- main as a brilliant piece of speculative investigation, far in advance of the time when it was written. The impor- tance attached to embryological evidence in the deter- mination of affinities marks the influence of the veteran embryologist, Von Baer. As an outcome of his researches on Medusz, the Royal Society now awarded the Royal Medal for Physiology to Huxley (Nov. 30, 1852), thus still further emphasizing the high position he had already secured in the scientific world. He and the other medallists were entertained at the anniversary dinner of the Society held on the same day, and he then spoke in moderate though unmistakable terms of the delayed grant to which allusion has already been made. ‘The way in which this speech was received clearly shows that the leading exponents of science fully sympathized with him in his position as regards the Admiralty, a sympathy indeed of which there had already been abundant proof. The year 1852 also marks the commencement of Huxley’s career as a lecturer, for on April 30 he delivered a discourse on ‘* Animal Individuality ” at the Royal Insti- tution (Proc. Roy. Inst., i, 1851-4, pp. 184-9. Sci. Mem., i, Xv, p. 146). Remembering the popularity to ROYAL INSTITUTION LECTURE 21 which he afterwards attained in this particular direction, it is interesting, though scarcely surprising to learn that his earlier efforts were not an unqualified success, owing to undue speed and the assumption of a conversational style. On this subject he remarks as follows in his Autobiography (Coll. Essays, i, p. 15) :— “At that time I disliked public speaking, and had a firm conviction that I should break down every time I opened my mouth, I believe I had every fault a speaker could have (except talking at random or indulging in rhetoric), when I spoke to the first important audience I ever addressed, on a Friday evening at the Royal Institution, in 1852. Yet, I must confess to having been guilty, malgré moi, of as much public speaking as most of my contemporaries, and for the last ten years it ceased to be so much of a bugbear to me. I used to pity myself for having to go through this training, but I am now more disposed to com- passionate the unfortunate audiences, especially my ever-friendly hearers at the Royal Institution, who were the subjects of my oratorical experiments.” The following two papers were published in 1853 :— I. ‘¢ Observations on the Existence of Cellulose in the Tunic of Ascidians” (Q. J. Micros. Sci., i, 1853. Sci. Mem., i, xxi, p. 221.)—This is an extension of his previous work on the subject. 2. “On the Development of the Teeth, and on the Nature and Import of Nasmyth’s ‘Persistent Capsule ’” (op. cit., i, 1853. Sci. Mem., i, xx11, p. 224).—In this paper Huxley, after describing the development of teeth, homologizes them with hairs, a view which is not now accepted. To these memoirs must be added a luminous exposi- tion of “The Cell Theory” (Brit. and For. Medico- Chir. Review, xii, 1853, pp. 285-314. Sci. Mem., i, XXIII, p. 242), which expounds the minute structure of 22 THOMAS HENRY HUXLEY organisms, and of which Sir Michael Foster justly states that it was,— ‘a paper which more than one young physiologist at the time read with delight, and which even to-day may be studied with no little profit,” and that ‘he, in this subject, as in others, drove the sword of rational inquiry through the heart of conceptions, metaphysical and transcendental, but dominant.”? (Obituary Notice, Proc. Roy. Soc., lix, 1895-6, p. lv). The Friday Evening Discourse ‘‘On the Identity of Structure of Plants and Animals,” delivered to the Royal Institution, April 15, 1853, is practically a lecture on the same theme (Proc. Roy. Inst., i, 1851-4, pp. 298-302 ; and Edinburgh New Philos. J., lili, 1852, pp. 172-7. Sci. Mem., i, xx, p. 216). During these years of stress Huxley not only estab- lished his reputation as a scientific investigator, and commenced his career as a lecturer, but also laid the foundation of that literary style which ultimately gave him a prominent position in the world of letters. To the Westminster Review he regularly contributed the article on ‘Contemporary Science,” was commissioned to write a AZanual on Comparative Anatomy for Messrs. Churchill, and so on. He estimated in fact that by _ means of his pen alone he was in the position to earn about £250 per annum, more than his Navy pay, and was therefore able to regard the decision of the Admir- alty with comparative equanimity, and prepared, if necessary, to wait in the hope that some congenial scien- tific post might fall to his lot. Just as Huxley’s inimitable powers as a lecturer were very largely the result of the most painstaking cultiva- tion, so also with his literary style. Comparatively few were privileged to hear him speak, but his writings have been and will remain a source of pleasure as well as LITERARY STYLE oR profit to countless thousands. Yet the eminently lucid easy style so many have admired was the result of laborious work and much re-writing, a concrete instance of that “ars celare artem” which has distinguished many masters of English prose. And his standard became ever higher as time went on. To quote the words of a well-known orator and man of letters, “in these days even a man of science is expected to be a good speaker and writer,” an expectation largely due to Huxley’s example, the outcome of his dictum that ‘ science and literature are not two things, but two sides of the same thing.” This salutary attitude has done no little for science, and something for literature. When, in 1891, de Varigny was engaged in translating some of Huxley’s works he received a letter containing this passage :— «‘The fact is that I have a great love and respect for my native tongue, and take great pains to use it properly. Some- times I write essays half-a-dozen times before 1 can get them into the proper shape; and I believe I become more fastidious as I grow older” (Life, ii, p. 291). It is a matter of common knowledge that these striv- ings after a proper use of the mother tongue were successful in no mean degree. CHAPTER IV BEGINNING OF PROFESSORIAL WORK IN LONDON [1854-8]. Tue year 1854 was a memorable one in many ways for Huxley. His friend Edward Forbes was appointed to an Edinburgh chair, and he succeeded him in London as Lecturer in Natural History in the Royal School of Mines with a stipend of £200 per annum, and later in the year became Naturalist to the Geological Survey at a commencing salary of like amount. He was also ap- pointed Lecturer in Comparative Anatomy at St. Thomas’s Hospital. Huxley always held very strongly that London was the best centre for scientific purposes, and proved true to his convictions by spending the rest of his work- ing life there, though he might, to his financial benefit, have become a professor in Edinburgh University. The death of Forbes later in the year was a heavy blow to him, and, by organizing a memorial fund, he helped to perpetuate the memory of one who had been his warmest and most loyal friend among the senior natura- lists of that time. By a singularly ironical stroke of fate, the Govern- ment grant which the Royal Society, for technical reasons, felt unable to award while he was still in the service of the Navy was now given him. The sum assigned was £300, and the Ray Society undertook to defray any further expense, and to publish the detailed investigations for which this grant was needed. ‘The much-delayed monograph was not published, however, 24 OCEANIC HYDROZOA 25 till 1858, under the name of “The Oceanic Hydrozoa: a Description of the Calycophoride and Physophoride observed during the Voyage of H.M.S. Rattlesnake, in the years 1846-1850.” To this classical work, which gives a detailed and comparative treatment of a difficult and then little-known group, and which is dedicated to Sir John Richardson, M.D., F.R.S., his old chief at Haslar, Huxley wrote a Preface, summarizing the diffi- culties that had prevented earlier publication, and acknow- ledging his indebtedness to MacLeay of Sydney, Edward Forbes, and others. The following “‘ Extract from a Memorandum by the Lords Commissioners of the Admiralty prefixed to the first edition of the ‘ Manual of Scientific Enquiry pre- pared for the use of Her Majesty’s Navy,’ edited by Sir J. F. W. Herschel, and published in 1849” is placed at the head of the Preface :— “It is the opinion of the Lords Commissioners of the Admiralty that it would be to the honour and advantage of the Navy and conduce to the general interests of Science, if new facilities and encouragement were given to the collection of information upon scientific subjects by the officers, and more particularly by the medical officers, of Her Majesty’s Navy, when upon foreign service. . . And it will be for their Lordships to consider whether some pecuniary reward or promotion may not be given to those who succeed in producing eminently useful results.”’ And from the Preface itself the following extracts are worth quoting :— «*The facts are these. I made a good many observations during our cruise, and sent home several papers to the Linnean and Royal Societies; but of these doves, or rather ravens, which left my ark, I had heard absolutely nothing up to the time of my return; and, save for the always kind und hearty encouragement of the celebrated William MacLeay, whenever 26 THOMAS HENRY HUXLEY our return to Sydney took me within reach of his hospitality, I know not whether I should have had the courage to continue labours which might, so far as I knew, be valueless. “On reaching England, however, I found not only that the Royal Society had thought my Memoir on the Medusz worthy of publication, but helping hands were stretched out to me on all sides; and among the men of science, I met with many generous friends whose sympathy and appreciation were bestowed in a measure, far beyond my deserts. Among these, the genial, and noble-minded Edward Forbes supported me with all that energy which he was wont to throw into his advocacy of the cause of a young man; and now that I have succeeded (though, alas! not replaced) him in the professorial chair he then held, and have some personal experience of an analogous variety of occupations and weight of responsibilities, I cannot reflect with- out emotion on the patient attention which he bestowed upon me, and the self-sacrificing zeal with which he exerted all his ‘ power, amity, and authority’ in my favour.” After narrating the unsuccessful attempts of his friends and himself to obtain the grant which the Admiralty minute seemed to warrant, he continues :— “It would be wearisome were I to narrate the history of their other efforts at length. In vain the Presidents of the Royal Society and of the British Association, separately and conjointly, officially and unofficially, solicited the Treasury ; in vain did I visit and write to, and I fear, bore, numerous persons in authority about this unfortunate grant. It must be confessed the business was troublesome enough while it lasted; but, in looking back, I would fain only remember with gratitude the zeal of the friends who aided me, and the long-suffering courtesy of the various Government officials, who listened so attentively to the claims of that Natural Science about which, unless I am greatly mistaken, they neither knew nor cared very much. «* During the three years the contest lasted, I reckon that the Admiralty was good enough to give me, in the form of pay, rather more than fifty pounds over the sum required, although, with steady consistency, their Lordships from the first refused to enable me to publish the work which they paid me for publishing. I by no means quarrel with an arrangement, which, PROSPECT OF MARRIAGE 24 although very annoying at the time, has been of the utmost service to me; for when, in 1854, their Lordships, as I suppose, weary of our pertinacity, cut the knot by calling upon me to serve afloat, new prospects had presented themselves, and, in giving up my commission, I obtained the long-sought funds for publication—the administrators of the Government Grant no longer objecting, that the Admiralty was pledged to supply its officers with funds for the publication of work done in its service.” The year 1854 not only brought Huxley some of the more solid rewards of success, but was satisfactory in another way, for, before his appointments fell to him, Mr. Heathorn had decided to come with his wife and daughter to England, there to reside permanently. And there was therefore an immediate prospect of marriage, after a long engagement, extending over a period of much anxiety and adversity. The scientific work published during this year includes the following :— I. “On the Vascular System of the Lower Annulosa” (Brit. Assoc. Rep., 1854, p. 109. Sci. Mem., i, xxiv, p- 279).—This highly speculative paper did good service by throwing doubt upon the then accepted view that certain sets of branching tubes in various worm-like forms and Echinoderms were equivalent to the blood system of higher Invertebrates. But at the same time, other homologies were suggested which subsequent research has shown to be untenable. ‘To criticize the early pioneer work of an eminent investigator is a particularly difficult task, but here and elsewhere Huxley was rather prone to jump at conclusions, an inherited character, regarding which he himself says, “ ... it has often stood me in good stead ; it has sometimes played me sad tricks, and it has always been a danger” (Autobiography, Coll. Essays, i, p- 4). 28 THOMAS HENRY HUXLEY 2. “On the Common Plan of Animal Forms” (Abstract of a Friday Evening Discourse delivered at the Royal Institution on May 12,1854. Proc. Roy. Inst., i, 1851-4, pp- 444-6. Sci. Mem., i, xxv, p. 28 1).—After demon- strating that Vertebrates, Annulosa, and Molluscs present variations on three common plans of structure (the same being also true for other great groups), the question is raised as to the nature of the relations, if any, between such plans, the conclusion being that they are specializa- tions of a more fundamental type, as indicated by the facts of embryology. Written in pre-Darwinian days the discourse is distinguished by what we should now call an evolutionary tone, implied rather than expressed. 3. “On the Structure and Relation of the Corpuscula Tactus (Tactile Corpuscles or Axile Corpuscles) and of the Pacinian Bodies” (Q. J. Micros. Soc., ii, 1854, pp. 1-7. Sci. Mem., i, xxvi, p. 284). 4. “On the Ultimate Structure and Relations of the Malpighian Bodies of the Spleen and of the Tonsillar Follicles” (op. cit., ii, 1854, pp. 74-82. Sci. Mem., i, XXVII, p. 291).— This and the preceding memoir are chiefly interesting as illustrating the author’s leaning towards the physiological aspect of natural history (cf: P- 4). An address delivered at St. Martin’s Hall, July 22, 1854, “On the Educational Value of the Natural History Sciences” (Coll. Essays, iii, p. 38), marks the beginning of one important side of Huxley’s life-work, i.¢., his persistent endeavour to secure a fitting place for science in education. In these later days, when our educational systems and ideals are undergoing revision, the claims of science are not likely to be forgotten, thanks very largely to the strenuous pioneer efforts of Huxley and men of his stamp. SCIENCE IN EDUCATION 29 In his Preface (dated September 4, 1893) to the volume of Collected Essays, in which this particular one is included, the author says :— “ The oldest piece, that ¢On the Educational Value of the Natural History Sciences,’ contains some crudities, which I re- pudiated when the lecture was first reprinted, more than twenty years ago ; but it will be seen that much of what I have had to say, later on in life, is merely a development of the propositions enunciated in this early and sadly-imperfect piece of work.” Imperfect or not, the essay, which includes a luminous exposition of the scientific method, contains some fine passages, of which perhaps the most famous is one which shows the influence of Hume :— ‘*So far as I can arrive at any clear comprehension of the matter, science is not, as many would seem to suppose, a modi- fication of the black art, suited to the tastes of the nineteenth century, and flourishing mainly in consequence of the decay of the Inquisition. Science is, I believe, nothing but srained and organised common sense, differing from the latter only as a veteran may differ from a raw recruit... .” And the summing-up paragraph is well deserving the most serious attention on the part of modern educa- tionists :— “: Biology needs no apologist when she demands a place—and a prominent place—in any scheme of education worthy of the name. Leave out the physiological sciences from your curri- culum, and you launch the student into the world, undisciplined in that science whose subject-matter would best develop his powers of observation ; ignorant of facts of the deepest impor- tance for his own and others’ welfare ; blind to the richest sources of beauty in God’s creation; and unprovided with that belief in a living law, and an order manifesting itself in and through endless change and variety, which might serve to check and moderate that phase of despair through which, if he take an earnest interest in social problems, he will assuredly sooner or later pass.” 30 THOMAS HENRY HUXLEY The Heathorns arrived in England in May 1855, and though unfortunately Miss Heathorn’s feeble health gave cause for great anxiety, her marriage took place on the following July 21, the summer being spent in Tenby. Even during the honeymoon Huxley busied himself with observations on a submerged forest at Amroth, and with other scientific work. At that time Darwin seems scarcely to have realized his pre-eminently strenuous nature, for he wrote, “I hope your marriage will not make you idle; happiness, I fear, is not good for work.” A warning of opposite kind would have been much more to the point. Huxley’s method of preparing lectures affords a good illustration of his indefatigable industry, in response to the prompting of a high ideal. Not content merely with acquainting himself with the relative literature, nor satisfied with his own unusually extensive know- ledge, he took a vast amount of pains to acquire a first-hand acquaintance with facts from one end of the animal kingdom to the other. His lectures, in short, often involved a considerable amount of original investigation. The following scientific memoirs require mention here :— 1. ‘Contributions to the Anatomy of the Brachiopoda” (Proc. Roy. Soc., vii, 1854-5, pp. 106-17, 241-2. Sci. Menm., i, XXXII, p. 325).—The ancient group of ‘lamp- shells,” of which the members possess a bivalve shell that suggests a relationship to molluscs, is still one that pre- sents many problems for solution, and naturally presented still more in the early fifties. The memoir embodies some very careful anatomical work, and throws doubt upon the interpretation of certain organs as “hearts,” doubt that has since been fully justified, for the organs VARIOUS RESEARCHES 31 in question are now well known to be connected with nitrogenous excretion. 2. “On a Hermaphrodite and Fissiparous Species of Tubicolar Annelide (Protula Dysteri) ” (Edinburgh New Philos. J., i, 1855, pp. 113-29. Sci. Mem., i, xxxu1, P- 337)-—This is a careful study of a marine worm, presenting many points of interest to the specialist. 3. “On the Structure of Noctiluca miliaris” (Q. J. Micros. Soc., iii, 1855, pp. 49-54. Sci. Mem., i, XXXIV, p. 351).—-We have here a contribution to our knowledge of an animalcule which is one of the causes of the phosphorescence of the sea. 4. ‘On the Enamel and Dentine of the Teeth” (op. cit., ili, 1855, pp. 127-30. Sci. Mem., i, xxxv, P- 357).—This is simply an answer to criticisms by M. Edouard Lent on a previous paper. 5. “ Tegumentary Organs” (in Todd’s Cyclopedia of Anatomy and Physiology, published in the parts which appeared between August 1855, and October 1856. Sci. Mem., i, xxxvill, p. 365).—This classical comparative study of the skin of animals marks, as Sir Michael Foster has pointed out, that leaning to the physiological side which circumstances prevented from having full play, and which can be traced to the influence of Johannes Miller. That influence, however, and the equally potent one of Von Baer, the father of embryology, deeply tinged a very large part if not the whole of Huxley’s scientific work. 6. ‘On Certain Zoological Arguments commonly Ad- duced in Favour of the Hypothesis of the Progressive Development of Animal Life in Time” (Abstract of a Friday Evening Discourse delivered at the Royal Insti- tution, April 20, 1855; Proc. Roy. Inst., ii, 1854-8, pp. 82-5. Sci. Mem., i, xxvm, p. 300).—The lecture 32. THOMAS HENRY HUXLEY combats the general view that ‘‘the history of life as a whole, in the past, is analogous to the history of each individual life in the present,” and affirms that “ the pro- gress of a higher animal in development is not through the forms of the lower, but through forms which are common to both lower and higher... .”. We find, in fact, that this pre-Darwinian discourse fully appreciates the nature of what is now known as Von Baer’s Law, the subject of much misapprehension down to quite recent times. And further one of the difficulties of the evolu- tion theory is here anticipated, 7.e., that the great sub- divisions of the animal kingdom are of vast antiquity, and were most or all specialized in times regarding which the geological record as yet is silent, so far as life is concerned. During the year 1855 Huxley gave his first course of lectures to working-men at Jermyn Street, thus initiat- ing a direction of his manifold activities which proved both valuable and extremely popular. With rare ex- ceptions, working men only were admitted to these courses, and curious subterfuges were sometimes resorted to in order to secure the much-coveted places in the auditorium. The writer knows of one such case, where a clerk succeeded in gaining admission by representing himself as a ‘‘driver,” suppressing a part of his full description as a “ quill-driver.” Before lecturing to this kind of audience Huxley wrote to his friend Dyster :— «‘T am sick of the dilettante middle-class, and mean to try what I can do with these hard-handed fellows who live among facts.” And in a subsequent letter, after paying a tribute to the earnestness and attention of the audience, he goes on to say :—‘‘I believe in the fustian, and can talk better to it than to any amount of gauze and Saxony... .” Certain it is that Huxley exerted LECTURES TO WORKING MEN 33 his great powers to the utmost in order to make these courses of lectures a success, and it has been considered that they were his best effort in the spoken presentment of scientific truths, an opinion which the present writer is inclined to endorse. CHAPTER V EARLY WORK ON FOSSILS AND BACKBONED ANIMALS. MUSEUM ARRANGEMENT [1856-8]. In 1856, Huxley’s official duties as Naturalist to the Geological Survey began to lead him away from the researches on the Invertebrates which had brought him such merited distinction. This diversion, though it ulti- mately led to work which was of the greatest import- ance in the evolution controversy, was much against his will, and he tells us in his Autobiography that when Sir Henry de la Beche offered him the posts of Naturalist to the Survey and Lecturer in Natural History vacated by Forbes,— “I refused the former point-blank, and accepted the latter only provisionally, telling Sir Henry that I did not care for fossils, and that I should give up Natural History as soon as I could get a physiological post. But I held the office for thirty-one years, and a large part of my work has been paleontological” (Coll. Essays, i, p. v). During the first sixteen years of his tenure of this office he produced no fewer than thirty-eight papers and memoirs on palzontological subjects. His first essay of the kind, ‘‘ On the Method of Palzon- tology” (Annals and Mag. Nat. Hist., xviii, 1856, pp. 43-54. Sci. Mem. i, xxx1x, p. 432), was particularly well received in North America, and was reprinted in 1869 by the Smithsonian Institute. It isin part an answer toan attack made by Dr. Falconer upon a Friday Evening 34 FOSSILS AND BACKBONED ANIMALS 35 Discourse ‘‘On Natural History, as Knowledge, Discip- line and Power,” given at the Royal Institution, February 15, 1856 (Proc. Roy. Inst., ii, 1854-8, pp. 187-95. Sci. Mem., i, xxx, p. 305). His position briefly was that paleontology is independent of the Cuvierian principle of physiological correlation or co- adaptation of organs, and is essentially the method of agreement. Utilitarian explanations of structure are also put out of court in somewhat summary fashion, an attitude which Darwinian principles have since rendered untenable in large degree. In the discourse, for instance, we read : “Who has ever dreamed of finding an utilitarian purpose in the forms and colours of flowers ...?” Yet every biologist now knows that Christian Konrad Sprengel gave good reasons for such a belief in his famous book, Das Entdeckte Geheimniss der Natur im Bau und in der Befruch- tung der Blumen, published at Berlin, 1793, a book for too long entirely forgotten. Of other scientific papers bearing date 1856, we have the following :— 1, ‘Observations on the Structure and Affinities of Himantopterus” (Q. J. Geol. Soc., xii, 1856, pp. 34-7. Sci. Mem., i, XL, p. 44.5).—The paper describes a member of an ancient extinct group which finds its nearest living allies among the king-crabs. 2. ‘Further Observations on the Structure of Appendi- cularia flabellum (Chamisso)” (Q. J. Micros. Sci., iv, 1856, pp. 181-91. Sci. Mem., i, xu1, p. 449).—This is a most valuable extension of a communication read before the Royal Society in 1851 upon a remarkable type of free- swimming Ascidian (cf p. 13). 3. ‘Note on the Reproductive Organs of the Cheilos- tome Polyzoa” (op. cit., iv, 1856, pp. 191-2. Sci. Menm., i. XLII, p. 461).—Here we have a short contribu- 36 THOMAS HENRY HUXLEY tion to our knowledge of a group that had already engaged the author’s attention (cf p. 20). One piece of work to which Huxley at this time turned his attention in his capacity as Naturalist to the Geo- logical Survey was that of museum arrangement. He re-organized the Museum of Practical Geology in Jermyn Street for teaching purposes, and from this period on took a great interest in various British collections of objects, whether public or private, large or small. In his opinion, a great central collection ought to be of a triple character, providing for the general public, the specialist, and the requirements of applied science. In many respects the magnificent Natural History Museum at South Kensington, as now arranged, realizes these ideals. “The Natural History Museum in Hamburg may also be pointed out as largely satisfying the requirements which Huxley deemed to be of such importance. As to’ local collections, he was strongly of opinion that they should primarily be of local character. And in a letter (dated December 8, 1872), to Mr. Alfred Walker, of Colwyn Bay, after emphasizing the importance of strictly local coltections, he adds, very characteristically :— “‘Whereas the ordinary lumber-room of clubs from New Zealand, Hindoo idols, sharks’ teeth, scorpions, mangy monkeys, and conch shells—who shall describe the weary inutility of it?” (Life, i, p. 136). The most important personal event during 1857 was the birth, on New Year’s Day, of his first child, a son, whose death nearly four years later was perhaps the greatest grief of his life, borne with that fortitude and resignation which distinguished him in times of adversity. Unfortunately during this year, and at but too frequent intervals during the rest of his life, Huxley suffered from severe attacks of bad health, for which the best cure PRELIMINARY LECTURES 37 proved to be walking tours in Britain or Switzerland. Considering that he was never robust, and taxed his strength to the utmost by all sorts of work, it is marvellous that he should have accomplished so much, especially when it is remembered that the last ten years of his life (sixty to seventy) were perforce comparatively unproduc- tive, so far as pure science is concerned. One result of summer holidays spent in Switzerland with Tyndall during this and the previous year were papers entitled, ‘‘ Observations on the Structure of Glacier Ice” (Phil. Mag., xiv, 1857, pp. 241-60. Sci. Mem. i, XLVI, p. 482), and “On the Structure and Motion of Glaciers” (Phil. Trans, Roy. Soc., cxlvii, 1857, pp. 327-46. Read January 15,1857. Sci. Mem. ii, 1, p. 1). Not content with giving his ordinary lectures in Jermyn Street, which many of his students were incapable of fully appreciating owing to want of acquaintance with funda- mental principles, Huxley began in 1857 to give a pre- liminary evening course of nine lectures, with the object of supplying the general knowledge necessary. These lectures consisted of “‘ physiography,” together with the preliminaries of paleontology, and a broad sketch of the classification, distribution, and morphology of organisms. His manifold activities now also included the duties in- volved by his position as Examiner in Physiology and Comparative Anatomy to the University of London. A Friday Evening Discourse at the Royal Institution was given (May 15) ‘‘ On the Present State of our Know- ledge as to the Structure and Functions of Nerve” (Proc. Roy. Inst., ii, 1854-8, pp. 432-7. Sci. Mem. i, xxx, p- 315).—In this lecture we have a further indication of strong physiological tendencies. In this year too he was elected an honorary member of the Microscopical Society of Giessen and the Academy 38 THOMAS HENRY HUXLEY of Breslau, the commencement of that general recogni- tion of his scientific eminence by foreign countries which was afterwards manifested in so large a measure. The scientific work for 1857 includes the following memoirs :— 1. “ Description of a New Crustacean (Pygocephalus Cooperi, Huxiey) from the Coal Measures” (Q. J. Geol. Soc., xiii, 1857, pp. 363-9. Sci. Mem., i, xxiu, p- 463). 2. On Dysteria; a New Genus of Infusoria” (Q. J. Micros. Sci., v, 1857, pp. 78-82. Sci. Mem., i, xxiv, p. 471).—This is an account of a marine animalcule, dis- covered by Dr. Dyster at Tenby. 3. “Review of Dr. Hannover’s Memoir: ‘ Ueber die Entwickelung und den Bau des Saugethierzahns’” (op. cit., v, 1857, pp. 166-71. Sci. Mem., i, xiv, p. 476). —This is a critical review of a research on the structure and especially on the development of mammalian teeth. 4. “On the Agamic Reproduction and Morphology of Aphis” (Trans. Linn. Soc., xxii, 1858, pp. 193-220, 221-36. Read November 5, 1857. Sci. Mem., ii, n, p. 26).—This classical memoir deals in detail with the structure and life-histories of Aphides (vide infra). Apart from the descriptive work it embodies generalizations of high value, and the influence of Von Baer is clearly trace- able in the emphasis laid upon embryological evidence. During 1858 the usual lectures were given, including a course on the ‘Principles of Biology” at the Royal Institution, the last of a triennial series delivered in the capacity of Fullerian Professor. A Friday Evening Dis- course “On the Phenomena of Gemmation” was de- livered at this Institution on May 21. This dealt with the extraordinary life-histories of Aphides, familiarly known as “‘ plant lice” or ‘green fly,” in which sexual SCIENCE IN SATURDAY REVIEW 39 and asexual modes of generation alternate (cf. No, 4, p- 38). (Proc. Roy. Inst., ii, 1854-8, pp. 534-8. Sci. Mem., i, XxxI, p. 321). . A particularly interesting feature of the year was the organization of a scientific column in the Saturday Review, the outcome of a conference between Huxley, Hooker and Tyndall, who were impressed with the desirability of making recent scientific work known to the general public as well as to specialists. The column was intended to serve the purpose of a “Scientific Review,” the launch- ing of which appeared at the time to be impracticable. Some years later (1861) the original project was to some extent realized by the publication of a quarterly Natural History Review, which became extinct in 1865. Mr. (now Sir Norman) Lockyer was the science editor of this publication, and the experience then gained enabled him in 1869 to initiate Nature, which flourishes to this day. During this year Huxley became a Fellow of the Linnean Society, and was elected a member of the Atheneum Club under the “ Distinguished Persons Rule.” His proposer for the latter was Sir R. J. Murchison: eighteen out of nineteen voted for the pro- position, and no one against it. Much of the scientific work for 1858 is embodied in the following memoirs :— 1. “On Cephalaspis and Pteraspis” (Q. J. Geol. Soc., xiv, 1858, pp. 267-80. Sci. Mem., i, xv, p. 502).— The structure of these extraordinary fossil forms, which we now know to be of lower grade than fishes, is care- fully discussed, and their possible affinities with certain members of the group of ordinary bony fishes are pointed out. 2. “Observations on the Genus Pteraspis ” (Brit. Assoc. Rep., 1858, Part 2, pp. 82-3. Sci. Mem., i, 40 THOMAS HENRY HUXLEY XLVIII, p. 517). The suggestions made by the author in the last memoir as to the affinities of these extinct types is repeated with rather more emphasis, on the strength of further evidence. The view tentatively advanced would not now be accepted, but the difficulty of the matter is fully realized, and there is a marked absence of dogmatic statement. 3. “On a New Species of Plesiosaurus, etc.” (Q. J. Geol. Soc., xiv, 1858, pp. 281-94. Sci. Mem., i, XLIX, p. §22).—This technical comparative memoir is an important contribution to our knowledge of a remarkable group of swan-necked marine reptiles which were dominant during the Mesozoic epoch. 4. “On Some Points in the Anatomy of Nautilus pompilius” (J. Linn. Soc. (Zool.), iii, 1859, pp. 36-44. Read June 3, 1858. Sci. Mem, ii, 111, p. 81).—This is an addition to our knowledge of the pearly Nautilus, the last survivor of a long series of extinct types. 5. “On the Theory of the Vertebrate Skull” (Proc. Roy. Soc., ix, 1857-9, pp. 381-457; Annals and Mag. Nat. Hist., iii, 1859, pp. 414-39. Sci. Mem., i, 1, p- 538).—Here we have an epoch-making memoir, which is in substance the Croonian lecture delivered before the Royal Society, June 17, 1858. It completely demolishes the transcendental theory of Oken that the skull is in reality composed of three modified vertebrae, and is therefore equivalent to a modified piece of the backbone. The facts of comparative anatomy and embryology are marshalled in a masterly fashion against this conception. At the same time the speculative views of Owen, founded upon those of Oken, are subjected to destructive criticism. This precluded any settlement of the rupture which had taken place the previous year between the two THEORY OF THE SKULL 41 specialists, the outcome of gradually increasing tension, for which Huxley was in nowise to blame. The im- portance of the memoir was long after summarized by Sir Michael Foster in his Obituary Notice of the author :— “ This lecture marked an epoch in England in vertebrate morphology, and the views enunciated in it carried forward, if somewhat modified, as they have been, not only by Huxley’s subsequent researches, and by those of his disciples, but especi- ally by the splendid work of Gegenbaur, are still, in the main, the views of the anatomists of to-day’ (Proc. Roy. Soc., lix, 1895-6, p. liv). CHAPTER VI THE ORIGIN OF SPECIES [1859]. TuerRE are three classical works, published at intervals of fifty years, which have exercised a far - reaching influence upon the progress of science and the develop- ment of thought in general. The first of these was Caspar Friedrich Wolff’s Theoria Generationis (1759), in which the progressive development of the individual by gradual upbuilding (epigenesis) from a simple germ is maintained as against the rival theory (then called ‘evolution”) asserting that this development consists merely in an expansion of parts present from the first. Fifty years later (1809) Lamarck published his Phil- sophie Zoologique, in which the progressive development of species (‘‘evolution” in the modern sense) is deduced from various classes of facts, and ascribed to the direct influence of surroundings (environment), of crossing, and of habits (use and disuse). After the lapse of still another half-century The Origin of Species by Means of Natural Selection, by Charles Darwin, made its appearance on November 24, 1859, being preceded (July, 1858) by joint communications to the Linnean Society made by the author and Alfred Russel Wallace, who had independently arrived at similar conclusions. The theory of Natural Selection is founded upon three classes of facts, i.e, the keen “struggle for existence” that undoubtedly takes place in nature as the result of rapid increase, the differences between members of the same species (variation), and 42 THE ORIGIN OF SPECIES 43 the transmission of characters from one generation to another (heredity). Individuals varying in directions giving them an advantage in the struggle for existence are more likely to survive and leave offspring than their fellows, i.e, have a better chance of being “naturally selected.” And the inheritance of such characters, in- creased in amount by further variation, may be supposed in the end to lead to sufficient divergence from the original stock to constitute new species, just as the “breeds” of domesticated animals have been brought into existence by “ artificial selection.” Until Darwin’s work appeared Huxley neither affirmed nor denied the possibility of transmutation of species, and his scientific work on the lines laid down by Johannes Miller and Von Baer kept him more than occupied, without troubling unduly about the matter. Even the influence of Herbert Spencer, who held evolution to be a logical necessity, had failed to make him adopt positive evolutionary views. Writing long afterwards on this point he says :— “I took my stand upon two grounds :—Firstly, that up to that time, the evidence in favour of transmutation was wholly insufficient ; and secondly, that no suggestion respecting the causes of transmutation assumed, which had been made, was in any way adequate to explain the phenomena. Looking back at the state of knowledge at that time, I really do not see that any other conclusion was justifiable’? (Darwin’s Life and Letters, ii. p. 188). In the same place Huxley tells us that the influence of Lyell, ‘‘was perhaps more potent than any other in keeping alive a sort of pious conviction that evolution, after all, would turn out true. I have recently read afresh the first edition of the Principles of Geology ; and when I consider that this remarkable 44 THOMAS HENRY HUXLEY book had been nearly thirty years in everybody’s hands, and that it brings home to any reader of ordinary intelligence a great principle and a great fact,—the principle that the past must be explained by the present, unless good cause be shown to the contrary ; and the fact that so far as our knowledge of the past history of life on our globe goes, no such cause can be shown,—I cannot but believe that Lyell, for others, as for my- self, was the chief agent in smoothing the road for Darwin. For consistent uniformitarianism postulates Evolution as much in the organic as in the inorganic world. The origin of a new species by other than ordinary agencies would be a vastly greater ‘catastrophe’ than any of those which Lyell successfully eliminated from sober geological speculation’ (pp. 189-90). Darwin attached great importance to the opinions of Lyell, Hooker and Huxley as regards his theory. After making a deep impression upon Lyell (who afterwards proclaimed himself a Darwinian, though with important reservations), and completely converting Hooker, he writes: “If I can convert Huxley I shall be content” (Darwin’s Life, ii, p. 221). And he subsequently had good cause for more than usual contentment, as Huxley’s vigorous championship of the new views, when these were ignorantly or fanatically attacked, brought them into great prominence and compelled that careful attention on the part of competent authorities without which their progress might have been indefinitely delayed. Huxley, however, was no unreasoning partizan, and, while accepting the Darwinian theory as a good working hypothesis, realized the difficulties involved and made no secret of them. In the Preface (dated April 7, 1893) to the second volume of his Collected Essays, he remarks :—- «© Those who take the trouble to read the first two essays (i.e. The Darwinian Hypothesis,’ and «The Origin of Species’) published in 1859 and 1860, will, I think, do me the justice to admit that my zeal to secure fair-play for Mr. THE ORIGIN OF SPECIES 45 Darwin did not drive me into the position of a mere advocate ; and that, while doing justice to the greatness of the argument, I did not fail to indicate its weak points. I have never seen any reason for departing from the position which I took up in these two essays; and the assertion which I sometimes meet with nowadays, that I have ‘ recanted’ or changed my opinions about Mr. Darwin’s views, is quite unintelligible to me.” A lecture ‘‘On the Persistent Types of Animal Life” (Proc. Roy. Inst., iii, 1858-62, pp. 151-3. Sci. Mem., ii, IV, p. 90), delivered at the Royal Institution on June 3, of this year, and in part the outcome of his work on Nautilus (one such type), anticipates one of the objec- tions afterwards brought against Darwinism, i.c., that it is not justified by the evidence of geology. The lecture points out that such persistence is only explicable on evolutionary grounds, and also lays stress on the imper- fection of the geological record. When, later in the year, the Origin made its appear- ance, Huxley, by a singular piece of good fortune, was entrusted with the review for the Times. This was written in Huxley’s best style, and the in- spiration of the subject enabled him to complete it with great rapidity, in strong contrast to his usual practice. In it he says :— «That this most ingenious hypothesis enables us to give a reason for many apparent anomalies in the distribution of living beings in space and time, and that it is not contradicted by the main phenomena of life and organization appear to us to be unquestionable.” But readers of the book are enjoined, in characteristic fashion, to maintain that spirit of— ‘doubt, which so loves truth, that it neither dares rest in doubt- ing, nor extinguish itself by unjustified belief.” 46 THOMAS HENRY HUXLEY And finally :— “Mr. Darwin abhors mere speculation as nature abhors a vacuum. He is as greedy of cases and precedents as any con- stitutional lawyer, and all the principles he lays down are capable of being brought to the test of observation and experi- ment. The path he bids us follow professes to be not a mere airy track, fabricated of ideal cobwebs, but a solid and broad bridge of facts. If it be so, it will carry us safely over many a chasm in our knowledge, and lead us to a region free from the snares of those fascinating but barren virgins, the Final Causes, against whom a high authority has so justly warned us ”’ (Coll. Essays, ii, p, 1). This year he was appointed Secretary to the Geological Society, a new kind of activity in which he rendered eminent service till 1885, when he resigned his Pre- sidency of the Royal Society. During the summer he also took part in a movement initiated by Dr. Carpenter, to which in part may be traced the origin of the marine biological stations that now play such an important réle in science. For he spent some time trawling off Arran, where Carpenter some years before had found suitable head-quarters in a cottage on Holy Island (in Lamlash Bay), and in the following winter carried out investigations on the spawning of herrings in the neigh- bourhood of Bute, this being the commencement of his fishery work. At Huxley’s request, Sir Roderick Murchison, then head of the Geological Survey, con- sented to subsidize this pioneer scheme for a term of years. Mention must also be made of the fact that Tyndall was at this time appointed Professor of Physics in the Royal School of Mines, a post which he retained till 1868, and this intimate association meant much to Huxley in a variety of ways, and cemented what was already a friendship of no common order. One aspect EXTINCT VERTEBRATES 47 of this is thus amusingly given in a letter to Hooker of the previous year :— “Why I value your and Tyndall’s and Darwin’s friendship so much is, among other things, that you all pitch into me when necessary. You may depend upon it, however blue I may look when in the wrong, it’s wrath with myself and nobody else” (Life, i, p. 157). The scientific memoirs of the year, chiefly palzonto- logical, are as follows :— 1. On the Stagonolepis Robertsoni (Agassiz) of the Elgin Sandstones; and on the Recently Discovered Footmarks in the Sandstones of Cummingstone” (Q. J. Geol. Soc., xv, 1859, pp. 440-60. Sci. Mem., ii, v, p- 94).— The remains of a supposed fossil fish are here proved to be in reality those of a crocodilian reptile. 2. “On some Amphibian and Reptilian Remains from South Africa and Australia” (op. cit., xv, 1859, pp. 642-9. Read March 3, 1859. Sci. Mem., ii, v1, p. 120). 3. ‘On a New Species of Dicynodon (D. Murrayi), from near Colesberg, South Africa; and on the Structure of the Skull in the Dicynodonts” (op. cit., xv, 1859, pp. 649-58. Read March 23, 1859. Sci. Mem., ii, VII, p. 130).—The reptile in question belongs to an extraordinary extinct group, among which the species of Dicynodon possess only two teeth, these being in the form of tusks projecting from the upper jaw. 4. “On Rhamphorhynchus Bucklandi, a Ptero- saurian from the Stonefield Slate” (op. cit., xv, 1859, pp. 658-70. Read March 23, 1859. Sci. Mem., ii, VIII, p, 141).—This deals with one of the extinct flying reptiles. 5. “On a Fossil Bird and a Fossil Cetacean from New Zealand” (op, cit., xv, 1859, pp. 670-7. Read 48 THOMAS HENRY HUXLEY March 23, 1859. Sci. Mem., ii, Ix, p. 157).—Two bones, belonging respectively to a large species of pen- guin and a porpoise-like Cetacean are described in this paper. 6. “On the Dermal Armour of Crocodilus Hast- ingsiz” (op. cit., xv, 1859, pp. 678-80. Read March 23, 1859. Sci. Mem., ii, x, p. 166).—Here an account is given of the bony scutes belonging to an extinct crocodile. 7. “On the Anatomy and Affinities of the Genus Pterygotus” (Mems. Geol. Survey U.K., Monograph I, 1859, pp. 1-36. Sci. Mem., ii, x1, p. 170).—This important monograph describes in detail the structure of a typical genus of an ancient extinct group, perhaps most nearly represented at the present day by the king- crabs. The conclusion is reached that the group may be regarded as an order of the Crustacea, an opinion which more recent research has to some extent modified. The relation to the extinct trilobites is also pointed out. 8. On Dasyceps Bucklandi (Labyrinthodon Buck- landi, Liyd)” (op. cit., 1859, pp. 52-6. Sci. Mem., ii, XI, p. 263).—The memoir describes the skull of one of those extinct armoured Amphibians which were dominant until their supremacy of the land was usurped by Reptiles. g. “On a Fragment of a Lower Jaw of a Large Labyrinthodont from Cubbington” (op. cit., 1859, pp. 56-7. Sci. Mem., ii, xvi, p. 269).—This paper has reference to another Amphibian belonging to the group just mentioned. 10. ‘ Observations on the Development of Some Parts of the Skeleton of Fishes” (Q. J. Micros. Sci., vii, 1859, pp» 33-46. Sci. Mem., ii, xv, p. 271).—The greater part of this particularly interesting memoir deals DEVELOPMENT OF FISHES 49 with the development of the tail of a species of stickle- back. It is a familiar fact that the tail of a shark or dog- fish, members of a very ancient group, is externally markedly unsymmetrical, there being a large upper lobe into or towards which the vertebral column is bent. The tails of the more modern bony fishes, e¢.g., herring, mackerel, and stickleback, are externally symmetrical, and the backbone appears to end off where its upper and lower lobes begin. A study of the development of the latter shows, however, that this kind of tail is merely an improvement of the older type, and that internally it is markedly unsymmetrical. 11. ‘*On the Dermal Armour of Jacare and Caiman, with Notes on the Specific and Generic Characters of Recent Crocodilia” (J. Linn. Soc. (Zool.), iv, 1860, pp- 1-28. Read February 15, 1859. Sci. Mem., ii, xv, p- 286).—The research embodied in this memoir was led up to by previous work upon extinct crocodilians. 12. “On the Anatomy and Development of Pyro- soma” (Trans. Linn. Soc., xxiii, 1862, pp. 193-250. Read December 1, 1859. Sci. Mem., ii, xvi, p. 313). — This classical monograph deals with a floating colonial tunicate or ascidian, which is one of the sources of the phosphorescence of the sea. The subject is worked out in detail, and alternation of generations established for the life-history. CHAPTER VII THE DEFENCE OF DARWIN [1860]. Tue year 1860 was destined to prove of great impor- tance for the progress of the new theory. During that year Huxley expounded and championed Darwin’s views to audiences of two kinds, i.e, to his familiar auditory at the Royal Institution, and before the British Associa- tion at Oxford. On Friday, February 10, he delivered a Friday Evening Discourse at the Royal Institution ‘« On Species and Races, and their Origin” (Proc. Roy. Inst., iii, 1858- 62, pp. 195-200; Annals and Mag. Nat. Hist., v, 1860, PP- 344-6. Sci. Mem., ii, xvi, p. 388).—After a lucid exposition of the nature of the Darwinian hypothesis, and some of the main facts upon which it is founded, the lecture ends with an eloquent appeal for fair treatment, without any shirking of the logical consequences of such arguments as may be regarded valid :— “Another, and unfortunately a large class of persons take fright at the logical consequences of such a doctrine as that put forth by Mr. Darwin. If all species have arisen in this way, say they—Man himself must have done so; and he and all the ani- mated world must have had a common origin. Most assuredly. No question of it. “But I would ask, does this logical necessity add one single difficulty of importance to those which already confront us on all sides whenever we contemplate our relations to the surround- ing universe? I think not. Let man’s mistaken vanity, his foolish contempt for the material world, impel him to struggle 50 THE DEFENCE OF DARWIN 51 as he will, he strives in vain to break through the ties which hold him to matter and the lower forms of life. . . . ‘T have said that the man of science is the sworn interpreter of nature in the high court of reason. But of what avail is his honest speech if ignorance is the assessor of the judge, and pre- judice foreman of the jury? I hardly know of a great physical truth, whose universal reception has not been preceded by an epoch in which most estimable persons have maintained that the phenomena investigated were directly dependent on the Divine Will, and that the attempt to investigate them was not only futile, but blasphemous. And there is a wonderful tenacity of life about this sort of opposition to physical science. Crushed and maimed in every battle, it yet seems never to be slain; and after a hundred defeats it is at this day as rampant, though happily not so mischievous, as in the time of Galileo. * But to those whose life is spent, to use Newton’s noble words, in picking up here a pebble and there a pebble on the shores of the great ocean of truth—who watch, day by day, the slow but sure advance of that mighty tide, bearing on its bosom the thousand treasures wherewith man ennobles and beautifies his life—it would be laughable, if it were not so sad, to see the little Canutes of the hour enthroned in solemn state, bidding that great wave to stay, and threatening to check its beneficent progress. ‘The wave rises and they fly; but unlike the brave old Dane, they learn no lesson of humility: the throne is pitched at what seems a safe distance, and the folly is repeated, “‘ Surely it is the duty of the public to discourage everything of this kind, to discredit these foolish meddlers who think they do the Almighty a service by preventing a thorough study of his works,” And again, after alluding to the contests which the new renascence of scientific thought was likely to in- volve :— ‘«‘ But I verily believe that come what will, the part which England may play in the battle is a grand and a noble one. She may prove to the world that for one people, at any rate, despotism and demagogy are not the necessary alternatives of government: that freedom and order are not incompatible ; that 52 THOMAS HENRY HUXLEY reverence is the handmaid of knowledge; that free discussion is the life of truth, and of true unity in a nation.” It is a somewhat curious fact that, but for the urgent request of Robert Chambers, Huxley had intended not to champion the cause of evolution in the now famous debate at the British Association in the summer, for he realized very fully the difficulties presented by a mixed audience, and the argumentum ad hominem that was sure to be employed on the other side. Preliminary skirmishing took place on Thursday, June 28, when, in the discus- sion that followed a paper by Dr. Daubeny, read before Section D, Owen stated as a fact that the gorilla’s brain “ presented more differences, as compared with the brain of man, than it did when compared with the brains of the lowest and most problematical of the Quadrumana.” Huxley’s special knowledge enabled him flatly to con- tradict so unwarranted an assertion, this ‘‘ unusual pro- cedure” being fully justified subsequently. The historic debate took place on the following Satur- day, when Wilberforce, the then Bishop of Oxford, crammed to the muzzle by Owen with undigested and inaccurate information, spoke, “For full half an hour with inimitable spirit, emptiness and unfairness... . Ina light, scoffing tone, florid and fluent, he assured us there was nothing in the idea of evolution ; rock- pigeons were what rock-pigeons had always been. Then, turn- ing to his antagonist with a smiling insolence, he begged to know, was it through his grandfather or his grandmother that he claimed his descent from a monkey?” (Reminiscences of a Grandmother, Macmillan’s Magazine, October 1898). Such mistaken flippancy helped the evolutionary cause in no small degree. Ignorance might be condoned, but not such an unworthy resort to the resources of mob THE DEFENCE OF DARWIN 33 oratory. As Professor Farrar afterwards wrote to Mr. Leonard Huxley :— ‘‘ His false humour was an attempt to arouse the antipathy about degrading woman to the quadrumana. Your father’s teply showed there was vulgarity as well as folly in the Bishop’s words, and the impression distinctly was, that the Bishop’s party, as they left the room, felt abashed, and recognised that the Bishop had forgotten to behave like a perfect gentleman” (Life, i, pp. 183-4, footnote). Huxley himself was the first to realize the advantage gained by the rhetorical error of the Bishop, remarking to Sir Benjamin Brodie, «‘ The Lord hath delivered him into mine hands.” No absolutely reliable account exists of Huxley’s reply, which after dealing with the scientific issues raised, ended with a retort that is not likely to be forgotten, Huxley himself was of opinion that the following rendering by the late John Richard Green approached most nearly to accuracy, but it is practically certain that the word ‘‘ equivocal” was not employed :— ‘¢I asserted—and I repeat—that a man has no reason to be ashamed of having an ape for his grandfather. If there were an ancestor whom I should feel shame in recalling it would rather be a maz—a man of restless and versatile intellect—who, not content with an equivocal success in his own sphere of activity, plunges into scientific questions with which he has no real acquaintance, only to obscure them by an aimless rhetoric, and distract the attention of his hearers from the real point at issue by eloquent digressions and skilled appeals to religious prejudice ”’ (Life, i, p. 185). Hooker, from the botanical side, completed the dis- comfiture of the anti-evolutionary forces. The Oxford meeting proved Huxley to be a debater of the first order, and from this time on he was justly regarded as the champion of Darwinian principles, and 54 THOMAS HENRY HUXLEY as illustrating the love of fair-play which is character- istic of a British audience, it is worth noting that on this occasion he was applauded almost as warmly as his antagonist on the conclusion of his speech. Though the personal tone imparted to the discussion, and for which he was not responsible, was distinctly repugnant to him, it must be confessed that he was essentially a fighting man, who rejoiced in ‘‘ smiting the Amalekites,” to use his own expression. Without his keen support at this critical juncture it is possible that the most luminous biological theory of the last century might have been considerably retarded in its progress, much to the detriment of science and intellectual advance in general. The vigorous essay on “‘ The Origin of Species ” (Coll. Essays, ii, p. 22), belonging to the same year, was a further important contribution to the promulgation and defence of Darwinism, of which the following well- known passages will always be quoted :— “In this nineteenth century, as at the dawn of modern physical science, the cosmogony of the semi-barbarous Hebrew is the incubus of the philosopher and the opprobrium of the orthodox. ... It is true that if philosophers have suffered, their cause has been amply revenged. Extinguished theologians lie about the cradle of every science as the strangled snakes about that of Hercules; and history records that whenever science and orthodoxy have been fairly opposed, the latter has been forced to retire from the lists, bleeding and crushed, if not annihilated ; scotched, if not slain.”’ And, after alluding to the recurrence of untenable idea :— ‘Philosophers, on the other hand, have no such aggressive tendencies. With eyes fixed on the noble goal to which ‘per aspera et ardua’ they tend, they may, now and then, be stirred to momentary wrath by the unnecessary obstacles with which the ignorant or the malicious encumber, if they cannot bar, the THE DEFENCE OF DARWIN | 55 difficult path ; but why should their souls be deeply vexed? The majesty of fact is on their side, and the elemental forces of Nature are working for them. ... Harmonious order governing eternally continuous progress—the web and woof of matter and force interweaving by slow degrees, without a broken thread, that veil which lies between us and the Infinite—that universe which alone we know or can know; such is the picture which science draws of the world, and in proportion as any part of that picture is in unison with the rest, so may we feel sure that it is rightly painted. Shall Biology alone remain out of harmony with her sister sciences ?” The following passages are of particular interest, being in some sort prophetic :— “Mr Darwin’s position might, we think, have been even stronger than it is if he had not embarrassed himself with the aphorism, Natura non facit saltum, which turns up so often in his pages. We believe, as we have said above, that Nature does make jumps now and then, and a recognition of the fact is of no small importance in disposing of many minor objections to the doctrine of transmutation. ... What if the orbit of Darwinism should be a little too circular? What if species should offer residual phenomena, here and there, not explicable by natural selection? . . . And viewed as a whole, we do not believe that, since the publication of Von Baer’s Researches on Development, thirty years ago, any work has appeared calculated to exert so large an influence, not only on the future of Biology, but in extending the domination of Science over regions of thought into which she has, as yet, hardly penetrated.” The defence of Darwinism in various ways, and before diverse audiences, by no means occupied the whole of Huxley’s time, lecture work apart, during 1860. This year, for example, witnessed the completion of the arrange- ments for bringing out the Natural History Review, regard- ing which enough has been said elsewhere (p. 39), and the first number of which appeared in January, 1861. Notice must also be made of a paper ‘ On the Structure of the Mouth and Pharynx of the Scorpion” (Q. J. 56 THOMAS HENRY HUXLEY Micros. Sci., viii, 1860, pp. 250-4. Sci. Mem., ii, x1x, P- 395).—This cleared up some obscure points in the structure of a common type, which in most respects had already been studied with considerable thoroughness. A scorpion feeds upon the juices of its prey, in adapta- tion to which its mouth is shown to be exceedingly small, and to open into a gullet connected with a pharynx serving as a sort of suction-pump. Another memoir of the year is ‘On a New Species of Macrauchenia (M. Bolivensis)” (Q. J. Geol. Soc., xvii, 1861, pp. 73-84. Read November 21, 1860. Sci. Men., ii, xx1, p. 403).—The extinct type dealt with, subsequently placed in a special group, is given as an example of the necessity for caution in making deductions, for it combines cameline and equine characters. It is further very interesting to find that Huxley rendered invaluable service to Herbert Spencer by going through the proofs of the First Principles, and offering valuable criticisms thereon. Similar good offices were continued for a long series of years. The desirability of higher education for women is now so widely approved in this country, and so largely carried into practice, that Huxley’s views on the subject, ex- pressed in a letter to Sir Charles Lyell (March 17, 1860), seem imbued with the spirit of to-day. The letter primarily referred to the question of admitting women to the membership of learned societies, in which matter there is even yet a good deal of conservatism, but its interest rather lies in the broader questions touched upon. The writer expresses a strong desire that the intellectual advancement and development of women should be pro- moted, and expresses his intention of giving his daughters a proper training in physical science, adding the following statement of belief as to the result that might be expected HIGHER EDUCATION OF WOMEN 57 to follow the general adoption of such a plan: “If other people would do the like, the next generation would see women fit to be the companions of men in all their pur- suits—though I don’t think men have anything to fear from their competition.” The letter concludes by strongly doubting whether such an educational advance would find general favour (Life, i, pp. 211-12). Unfortunately the year was not to pass without deep personal sorrow, for on September 15, Huxley’s first- born son died very suddenly from scarlet fever. The birth of a second son later in the year afforded some consolation, nor was there wanting the sympathy of as staunch friends as any man ever had. In a long and candid letter, in answer to one received from Charles Kingsley, we find the principles of agnostic philosophy fully set forth, and a statement of entire belief in the absolute justice of Nature. CHAPTER VII DISSEMINATION AND SUPPORT OF EVOLUTIONARY DOCTRINES [1861-2]. THE crushing bereavement mentioned in the last chapter increased rather than diminished the amount of work done by Huxley during the following year (1861). Partly, no doubt, because he recognized that work is the only panacea for human ills, and partly owing to his intensely energetic nature, constructed as he was ‘on the high-pressure tubular-boiler principle,” to use his own description. Here, too, we may possibly trace the influence of Carlyle. The vigour with which fresh labours were begun and old ones continued, was partly the result of a Christmas vacation spent in mountain climbing in Snowdonia. Darwin, Lyell and Hooker, all entered kindly remon- strances against the immense amount of work not only undertaken, but actually accomplished, and there is no doubt that their advice was fully justified, for Huxley grew old before his time, and ultimately broke down at a comparatively early age. But every man must work in his own manner, and the advancement of science was very possibly better served by concentrated efforts. Hooker’s remonstrance is of particular interest, for it expresses in some sense what many have felt :— “Do take the counsel of a quiet looker-on and withdraw to your books and studies in pure Natural History ; let modes of thought alone. You may make a very good naturalist or a very 58 EVOLUTIONARY LECTURES — 59 good metaphysician (of that I know nothing, don’t despise me), but you have neither time nor place for both ”’ (Life, i, p- 229). There is, however, no doubt as to the “ good natura- list,” but regarding the rest opinion would scarcely be unanimous. Much of the work of 1861 naturally had reference to evolution, whether by way of exposition or in the form of research lending support to Darwin’s views. In the early part of the year he lectured to working- men on ‘‘ The Relation of Man to the rest of the Animal Kingdom,” a subject to which he had for some time devoted special attention, and which was naturally the central point about which the controversial war waged most bitterly. On this particular audience he obviously made a deep impression, and humorously remarks in a letter to his wife—‘ By next Friday evening they will all be convinced that they are monkeys” (Life, i, p. 190). Two lectures, included in his published works, come under the pro-Darwinian utterances. One was a Friday Evening Discourse (February 8) at the Royal Institution, “On the Nature of the Earliest Stages of the Develop- ment of Animals” (Proc. Roy. Inst., iii, 1858-62, Pp. 315-7. Sci. Mem., ii, xx, p. 400).—Taking the development of the free-swimming colonial ascidian Pyro- soma as a text (of p. 49), the early evolution of the individual is described, and shown to be a matter of gradual up-building, step by step (epigenesis), a passage from simple to complex, and not a mere increase in size (evolution in the older sense). In short, the discourse illustrates the principles of development first laid down by Caspar Friedrich Wolff (cf p. 42). The second lecture, delivered at South Kensington, was entitled, ‘‘ A Lobster: or the Study of Zoology” 60 THOMAS HENRY HUXLEY (Coll. Essays, viii, p. 196). The particular volume of Collected Essays in which this is reprinted largely con- sists of popular lectures, and the following extract from the Preface (dated April, 1894) shows that Huxley attached great importance to discourses of the kind, if undertaken in a proper spirit :— «. .. . Lhave not been one of those fortunate persons who are able to regard a popular lecture as a mere hors-d’euvre, un- worthy of being ranked among theseriousefforts of a philosopher ; and who keep their fame as scientific hierophants unsullied by attempts—at least of the successful sort—to be understanded of the people. On the contrary, I found that the task of putting the truths learned in the field, the laboratory and the museum, into language which, without bating a jot of scientific accuracy shall be generally intelligible, taxed such scientific and literary faculty as I possess to the uttermost ; indeed my experience has furnished me with no better corrective of the tendency to scholastic pedantry which besets all those who are absorbed in pursuits remote from the common ways of men, and become habituated to think and speak in the technical dialect of their own little world, as if there were no other.” In this lecture the anatomy and physiology of a lobster are reviewed, and used to‘ illustrate some of the general principles of biology, after which the proper methods of teaching physical science in general and zoology in particular are laid down, and the claims of science to an important place in education vindicated. Those who are interested in the complex educational problems, the solution of which exercises us to-day, would do well to study this essay, now over forty years old. The essence of the much debated ‘type-system,” with the establishment of which Huxley had so much to do, is embodied in the following sentence :— ‘“ The great matter is, to make teaching real and practical, by TEACHING OF SCIENCE 61 fixing the attention of the student on particular facts; but at the same time it should be rendered broad and comprehensive, by constant reference to the generalizations of which all par- ticular facts are illustrations.” The respective uses of lectures, demonstrations and examinations, as parts of the educational machinery, are then discussed, and the lecture concludes with a protest against existing systems of instruction, and an eloquent appeal that science be given her proper place :— ‘« Modern civilization rests upon physical science; take away her gifts to our own country, and our position among the leading nations of the world is gone to-morrow; for it is physical science only that makes intelligence and moral energy stronger than brute force. The whole of modern thought is steeped in science; it has made its way into the works of our best poets, and even the mere man of letters, who affects to ignore and despise science, is unconsciously impregnated with her spirit, and indebted for his best products to her methods.” In the British Association Meeting of 1860, Huxley’s unrivalled anatomical knowledge had enabled him to flatly contradict the statement made by Owen that man is marked off from all other animals by the structure of his brain, a promise being at the same time made that in due course the contradiction should be fully justified. This, of course, led to renewed investigations on the subject now to be published. The first contribution of the kind to science, *‘ On the Zoological Relations of Man with the Lower Animals,” appeared in the first number of the Natural History Re- view (1861, pp. 67-84. Sci. Mem., ii, xxvi, p. 471), and in this, after discussing a number of the leading features of human anatomy, the author accepts the old Linnean view “that Man is to be regarded as a genus of 62 THOMAS HENRY HUXLEY the same order as that which contains the Quadrumana [z.c., apes and monkeys].” A technical memoir, “On the Brain of Ateles paniscus” (Proc. Zool. Soc., 1861, pp. 247-60. Sci. Menm., ii, xxv, p. 493), proves that certain structures asserted to be peculiar to man are present in the brain of this species of spider-monkey, a comparatively low type. The following important paleontological memoirs also made their appearance in 1861 :— 1. “On Pteraspis Dunensis (Archzoteuthis Dunensis, Roemer)” (Q. J. Geol. Soc., xvii. 1861, pp. 163-6. Read January 23, 1861. Sci. Mem., ii, xxu, p. 417). —The fossil described was shown to be the head-shield of an ancient vertebrate, and not the pen of an extinct cuttle-fish, as supposed by the first describer. The affinity with sturgeons suggested has not been justified by subsequent research, Pteraspis and its allies being now regarded as constituting a group lower in the scale than any known fishes. 2. ‘Preliminary Essay upon the Systematic Arrange- ment of the Fishes of the Devonian Epoch” (Mems. Geol. Survey U.K., Decade X., 1861. Sci. Mem., ii, XXIII, p. 421).—In this important memoir the founda- tions of a rational classification of extinct fishes, especially those known as Ganoids (of which sturgeons are the best-known living examples), are laid down. In the same decade two memoirs on particular extinct types of fish are included, i.e. :— 3. “ Glyptolemus Kinnairdi” (op. cit., pp. 41-6. Sci. Mem., ii, xxIv, p. 461); and 4. ‘ Phaneropleuron Andersoni” (op. cit., pp. 47-9. Sci. Mem., ii, xxv, p- 467). Huxley had already made a special study of the verte- brate skull (cf p. 40), and in the course of this year con- MAN AND LOWER ANIMALS _ 63 tinued his work in that direction, investigating cranial development in the chick. This subsequently led on to particularly valuable and epoch-making work on the classification of birds. Examinations and continued assistance given to Spencer in the matter of proof-sheets helped to swell the enormous amount of work done during the year. 1862. In January, 1862, two lectures were given in Edinburgh, “On the Relation of Man to the Lower Animals” (Coll. Essays, vii, p. 77).—After a preliminary sketch of de- velopment, the physical structure of man is compared with that of the apes, and the conclusion reached that there is no greater structural barrier between the two than between the higher apes and ordinary monkeys. Darwinism is then advanced as the only hypothesis as to the origin of species “ which has any scientific existence.” No attempt is made to slur over the provisional nature of that hypothesis, the weak points in which are fully set forth; and after denial of mere partizanship Huxley gives in brief the reasons which induced him provisionally to accept the hypothesis :— «©, . , . the last position in which I wish to find myself is that of an advocate for Mr. Darwin’s, or any other views; if by an advocate is meant one whose business it is to smooth over real difficulties and to persuade where he cannot convince. “5. Royal Commission uponthe Administration and Operation of the Contagious Diseases Acts (1870-1). 6. Royal Commission on Scientific Instruction and the Advancement of Science (1870-5). 7. Royal Commission on the Practice of sub- jecting Live Animals to Experiments for Scientific Pur- poses (1876). 8. Royal Commission to inquire into the Universities of Scotland (1876-8). 9. Royal Com- mission on the Medical Acts (1881-2). 10. Royal 98 LONDON SCHOOL BOARD 99 Commission on Trawl, Net and Beam Trawl Fishing (1884). Administrative work in connection with various learned societies consumed an increasing amount of time, especially the heavy duties associated with the Secretaryship of the Royal Society, which he held from 1872-81, afterwards becoming President (1883-5). Before 1870 Huxley had not been content merely with demonstrating, by the example of his own courses, the methods which ought to be employed in order to make the specialist teaching of science really efficient, but he had also taken every opportunity of expressing his views as to the place of science in a school curriculum, and as to the unsatisfactory nature of school education in Britain (cf: p.- 91). Largely as the result of the part he played in the intellectual renascence to which the theory of evolution gave so powerful an impetus, profound dis- content had gradually arisen in this country with the dis- organized state of elementary education, which found practical expression in the passing of W. E. Forster’s Education Act in 1870. Huxley fortunately conceived it to be his duty to offer himself as a candidate for the first London School Board, and without taking any steps beyond some addresses given at public meetings, was returned for the Marylebone division on November 29, being second on the poll. His reasons for coming forward are thus summarized by Mr. Leonard Huxley (Life, i, p. 337) :— “ This [#,e., the London School Board] was the practical out- come of the rising interest in education all over the country; on its working, he felt, depended momentous issues—the fostering of the moral and physical well-being of the nation; the quickening of its intelligence and the maintenance of its commercial supremacy. Withal, he desired to temper ‘book-learning’ with 100 THOMAS HENRY HUXLEY something of the direct knowledge of nature: on the one hand, as an admirable instrument of education, if properly applied; on the other, as preparing the way for an attitude of mind which could appreciate the reasons for the immense changes already beginning to operate in human thought.” In an article in the Contemporary Review (1870) on «The School Boards: what they can do, and what they may do” (Coll. Essays, iii, p. 374), we find a sketch of what Huxley considered elementary education should in- clude, arranged under four heads :—“ 1. Physical training and drill, as part of the regular business of the school. 2. Next in order to physical training I put the instruc- tion of children, and especially of girls, in the elements of household work and of domestic economy ; in the first place for their own sakes, and in the second for that of their future employers.” 3. Ethical and religious training. 4. Intellectual training, including not only reading, writ- ing and arithmetic, but also the elements of physical science, with drawing, modelling and singing. The considerations advanced under the third heading are in these days of particular interest. One provision of the Act ran as follows :— “No religious catechism or religious formulary which is distinctive of any particular denomination shall be taught in the school.” Mr. Forster afterwards defined the kind of religious in- struction permitted by the Act :— «T have the fullest confidence that in the reading and explaining of the Bible, what the children will be taught will be the great truths of Christian life and conduct, which all of us desire they should know, and that no effort will be made to cram into their poor little minds theological dogmas which their tender age prevents them from understanding.”’ In the article now under consideration Huxley. very RELIGION IN SCHOOLS 101 clearly defines his own position in regard to the religious question, and since that position has been much misunder- stood and often misrepresented, it will be well to make it clear. He deplores the current confusion between religion and theology, beginning with the statement that, from the intellectual side, the laws of conduct are a part of moral science, while, “all that has any unchangeable reality in religion” is beyond science, and constituted by «©... the engagement of the affections in favour of that particular kind of conduct which we call good . . . together with the awe and reverence, which have no kinship with base fear, but arise whenever one tries to pierce below the surface of things, whether they be material or spiritual. . . .” Elsewhere he gives the brief definition :— “Teach a child what is wise, that is morality. Teach him what is wise and beautiful, that is religion” (Life, i, p. 343, Note 1). This naturally calls to mind one of the Platonic ideals, as expressed in the following passage, which follows Plato’s criticism of poets :— « This being the case, ought we to confine ourselves to superin- tending our poets, and compelling them to impress on their productions the likeness of a good moral character, on pain of Not composing among us; or ought we to extend our superin- tendence to the professors of every other craft as well. . .? Ought we not, on the contrary, to seek out artists of another stamp, who, by the power of genius can trace out the nature of the fair and the graceful, that our young men, dwelling as it were in a healthful region, may drink in good from every quarter, whence any emanation from noble works may strike upon their eye or their ear, like a gale wafting health from salubrious lands, and win them imperceptibly from their earliest childhood into resemblance, love, and harmony with the true beauty of reason ?”” (The Republic of Plato, translation of Davies and Vaughan, new edition, 1874, pp. 96-7). 102 THOMAS HENRY HUXLEY Huxley was undoubtedly a supporter of secular educa- tion, defined as ‘education without theology,” but there were then as now secularists and secularists, and so far from being the leader of those included in the first London School Board, he was entirely opposed to their views, quite as much as to those of the so-called “ religious party ” :— “¢ For, leaving aside the more far-seeing minority on each side, what the ‘religious’ party is crying for is mere theology, under the name of religion; while the ‘secularists’ have unwisely and wrongfully admitted the assumption of their opponents, and demand the abolition of all ‘religious’ teaching, when they only want to be free of theology—burning your ship to get rid of the cockroaches ! ”” And further :— «*. . . If I were compelled to choose for one of my own children, between a school in which real religious instruction is given, and one without it, I should prefer the former, even though the child might have to take a good deal of theology with it.” Huxley’s eloquent plea for the use of the Bible in schools, as the only practical measure by which “the religious feeling, which is the essential basis of conduct,” can be kept up in this country, has often been quoted, but will bear quoting again :— “Take the Bible as a whole; make the severest deductions which fair criticism can dictate for shortcomings and positive errors; eliminate, as a sensible lay-teacher would do, if left to himself, all that it is not desirable for children to occupy them- selves with; and there still remains in this old literature a vast residuum of moral beauty and grandeur. And then con- sider the great historical fact that, for three centuries, this book has been woven into the life of all that is best and noblest in English history ; that it has become the national epic of Britain, and is as familiar to noble and simple, from John o’ Groats USE OF THE BIBLE 103 House to Land’s End, as Dante and Tasso once were to the Italians ; that it is written in the noblest and purest English, and abounds in exquisite beauties of mere literary form ; and finally, that it forbids the veriest hind who never left his village to be ignorant of the existence of other countries and other civilizations, and of a great past, stretching back to the furthest limits of the oldest nations in the world. By the study of what other book could children be so much humanized and made to feel that each figure in that vast historical procession fills, like themselves, but a momentary space in the interval between two eternities; and earns the blessings or the curses of all time, according to its effort to do good and hate evil, even as they also are earning their pay- ment for their work ?”” To this, however, it is only fair to add the statement of Mr. Leonard Huxley that his father, “©... would not have used the Bible as the agency for introducing the religious and ethical idea into education if he had been dealing with a fresh and untouched population” (Life, i, ps 343). Of course not, for adaptation to existing environments is in the essence of all progress. As a member of the London School Board, Huxley did his best to carry into effect the views just explained, supporting, for example, a resolution proposed by Mr. W. H. Smith, M.P., and carried by a large majority, to the effect :— “That, in the schools provided by the Board, the Bible shall be read, and there shall be given therefrom such explanations and such instruction in the principles of religion and morality as are suited to the capacities of children.” Unfortunately ill health necessitated resignation of his seat on the Board in the early part of 1872, though even during the brief space of fourteen months for which he served he had succeeded in realizing some part of his 104 THOMAS HENRY HUXLEY ideals as to elementary education. As was to be expected, Huxley made a deep impression upon his fellow-members, many of whom had felt no small dismay at his election. Such fears were soon dispelled by his straightforward honesty, consideration for the opinions of others, and strong common sense. And there can be no doubt that his resignation was accepted with very real regret. Our debt to him in respect of elementary education, and the personal impression he made on the School Board, will be fully realized by reading the contributions furnished by Dr. J. H. Gladstone to Mr. Leonard Huxley for bio- graphical purposes (Life, i, pp. 349-50). The essence of the matter is contained in the following brief extracts from this contribution :— “ On February 7 [1872], a letter of resignation was received from him.... The Rev. Dr. Rigg, Canon Miller, Mr. Charles Read, and Lord Lawrence [the Chairman] expressed their deep regret. In the words of Dr. Rigg, ‘they were losing one of the most valuable members of the Board, not only because of his intellect and trained acute- ness, but because of his knowledge of every subject connected with culture and education, and because of his great fairness and impartiality with regard to all subjects that came under his observation.” Though Huxley quitted the Board after only fourteen months’ service, the memory of his words and acts combined to influence it long afterwards. ... It was our duty to put into practice the scheme of instruction which Huxley was mainly instrumental in settling. . . . Kindergarten methods have been promoted. Drawing, on which Huxley laid more stress than his colleagues generally did, has been enor- mously extended and greatly ‘revolutionized in its methods, Object lessons and elementary science have been introduced everywhere, while shorthand, the use of tools for boys, and cookery and domestic economy for girls, are becoming essentials in our schools. Evening continuation schools have lately been widely extended. Thus the impulse given by Huxley in the first months of the Board’s existence has been carried forward by others, and is now affecting the minds of the half million of boys and girls in the INFLUENCE ON BOARD SCHOOLS 105 Board Schools of London, and indirectly the still greater number in other schools throughout the land.” Huxley’s influence endures to-day not merely in the general character of elementary instruction, but also in the easily available means by which pupils of ability are enabled to take advantage of higher education. Indeed, the ‘‘ educational ladder” is perhaps set at too easy an angle. Baseless assertions were made at the time that Huxley was led by personal ambition to become a member of the School Board, and that he contemplated a political career. As a matter of fact the opportunity was more than once afforded him of offering himself as a candidate to a parliamentary constituency, and in the opinion of those most competent to judge, eg., Sir Mountstuart Grant Duff (Life, i, pp. 354-5), he would have proved a brilliant success in the House of Commons, provided the strain had not proved too much for his physical en- durance. For the sake of continuity Huxley’s School Board work has been taken as a whole, and it will now be necessary to go back to 1870 for the purpose of considering other events and other kinds of activity. The publication of Lay Sermons, Addresses and Reviews during this year, largely extended his influence as an educationist, and met with a large and increasing popularity. A volume of selections from it was published during the following year. An address “‘On Medical Education” (Coll. Essays, iii, p. 303), given during 1870 to the medical students of University College, London, contains some very in- teresting suggestions, some of which might still be carried out with advantage, despite the many advances which have been made during the last thirty-five years. The 106 THOMAS HENRY HUXLEY importance to medical students of some school training in chemistry, physics and botany is emphasized, some criticism is directed against the current methods of teaching and acquiring a knowledge of physiology, and the abolition of comparative anatomy and materia medica from the medical curriculum advocated. Besides this it is strongly urged that, in the interest of the London medical schools, the teaching of the theoretical subjects in the course of study ought to be centralized in two or three insti- tutions. One of Huxley’s most famous addresses, that “On Descartes’ ‘ Discourse touching the Method of using one’s Reason rightly and of seeking Scientific Truth,’” was delivered on March 24, to the Cambridge Y.M.C.A. (Coll. Essays, i, p. 166). The address is not merely interesting as a lucid exposition of Cartesian philosophy, but also because it demonstrates that this philosophy was one of the important influences that had helped to bring about MHuxley’s characteristic intellectual attitude :— ‘« This golden rule is—give unqualified assent to no proposi- tions but those the truth of which is so clear and distinct that they cannot be doubted. ‘The enunciation of this great first commandment of science consecrated Doubt. It removed Doubt from the seat of penance among the grievous sins to which it had long been condemned, and enthroned it in that high place among the primary duties, which is assigned to it by the scientific conscience of these latter days... . When I say that Descartes consecrated doubt, you must remember that it was that sort of doubt which Goethe has called, ‘the active scepticism, whose whole aim is to conquer itself;’ and not that other sort, which is born of flippancy and ignorance, and whose aim is only to perpetuate itself, as an excuse for idleness and indifference.” Another very well-known lecture, “On the Formation PALHONTOLOGY & EVOLUTION 107 of Coal” (Coll. Essays, viii, p. 137), was delivered at the Philosophical Institute, Bradford, and much resembles in character the one ‘On a Piece of Chalk,” given two years previously (cf. p. 87). The following are the scientific memoirs and more technical addresses of 1870 :— 1. ‘Anniversary Address of the President” (Q. J. Geol. Soc., xxvi, 1870, pp. xxix-lIxiv. Delivered February 18, 1870. Sci. Mem., iii, xxx, p. 510. Re- printed under the title of ‘‘ Paleontology and the Doctrine of Evolution,” in Coll. Essays, viii, p. 340),—The more important of the deceased Fellows to whom tributes were paid are the Vicomte d’Archiac, J. Beete Jukes, H.C. E. von Meyer and J. W. Salter. The address may be described as bringing a previous one up to date. In memoirs already dealt with (cf pp. 89, 95) Huxley had pointed to certain extinct reptiles (Ornithoscelida, a group of Dinosauria) as being the animals most nearly inter- mediate between reptiles and birds. Here he adds :— ‘“*, . , it is very doubtful whether any of the genera of Orni- thoscelida with which we are at present acquainted, are the actual linear types by which the transition from the lizard to the bird was effected. These, very probably, are still hidden from us in the older formations.” This view has been amply endorsed by subsequent research, We have also the famous account of the pedigree of the horse, so far as then known. Existing equine quadrupeds, wlth their one-toed extremities (pos- sessing, however, in the ‘‘splint-bones,” vestiges or rudiments of two others), and complex grinding teeth, are traced back to earlier three-toed forms (Hipparion, Anchitherium, Plagiolophus), in which the teeth in question are simpler in character. And in connection 108 THOMAS HENRY HUXLEY with this comes the famous prophecy now completely fulfilled :— “Tf the expectation raised by the splints of the horses that, in some ancestor of the horses, these splints would be found to be complete digits, has been verified, we are furnished with very strong reasons for looking for a noless complete verifica- tion of the expectation that the three-toed Plagiolophus-like ‘avus’ of the horse must have had a five-toed ‘ atavus’ at some earlier period.”’ 2. “ Onthe Milk Dentition of Paleotherium magnum” [an extinct mammal related to the elephants] (Geol. Mag., vii, 1870, pp. 153-5. Sci. Mem., iii, xxxv, p. 595). 3. “Triassic Dinosauria” (Nature, i, 1870, pp. 23-4. Sci. Mem., ili, xxxvI, p. 599). 4. “On the Ethnology of Britain” (J. Ethnol. Soc., New Series, ii, 1870, pp. 382-4. Read May 10, 1870. Sci. Mem., iii, xxx1, p. 551). Afterwards published in the Contemporary Review under the title of ‘Some Fixed Points in British Ethnology ” (Coll. Essays, vii, p. 253). 5. ‘Anniversary Address of the President” (op. cit., pp. xvi-xxiv. Delivered May 24, 1870. Sci. Mem., iii, XXXII, p. 554).—We gather from this that Huxley was trying to bring about an amalgamation between the Ethnological and Anthropological Societies, the aims of which were practically the same. His views as to the racial nature of the inhabitants of the west of England appear to have given offence to an individual who attacked him in the Pall Mall Gazette, under the mom de plume of “A Devonshire Man,” and unwisely launched into personalities, which elicited the following withering retort :— ““¢ A Devonshire man’ is good enough to say of me that ‘cutting up monkeys is his forte, and cutting up men is his BIOGENESIS AND ABIOGENESIS 109 foible.” With your permission, I propose to cut up ‘ A Devon- shire Man’; but I leave it to the public to judge whether, when so employed, my occupation is to be referred to the former or to the latter category ” (Life, i. pp. 325-6). 6. “On the Geographical Distribution of the Chief Modification of Mankind” (op. cit., pp. 404-12. Read June 7, 1870. Sci. Mem, iii, xxx, p. 564). 47, ‘Presidential Address to the British Association at Liverpool” (Rep. Brit. Assoc. (1870), 1871, pp. Ixxiii- Ixxxix. Sci. Mem., iii, xxxiv, p. 572. Coll. Essays, viii, p. 229).—This deals with ‘‘ Biogenesis and Abiogenesis,” the origin of life from life, as against ‘‘ spontaneous generation,” or conversion of non-living matter into living. After a sketch of the history of the question, showing how abiogenesis had gradually been disproved for the more obvious organisms, an account is given of the way in which Pasteur and others disproved it for bacteria, the last stronghold of the spontaneous generationists. Huxley himself repeated these experiments, and some of the flasks of sterilized hay-infusion he employed long afterwards figured on his lecture bench. But while the address clearly sets forth the disproof of all supposed cases of abiogenesis so far as the present is concerned, it proceeds to the logical conclusion that as an “‘act of philosophic faith” it is necessary to believe that the first living matter was so formed. It is suggested that the earliest organisms must have been independent of light, feeding in much the same way as fungi do now. This last view has not found general acceptance. Prominence is given to the practical bearing of re- searches on bacteria, and other lower forms, on the treat- ment of contagious and infectious diseases, whether of human beings, animals or plants. The pioneer work of Pasteur on the silkworm disease known as pébrine is 110 THOMAS HENRY HUXLEY quoted, and scarlet fever is spoken of asa disease that will ultimately be stamped out :— « And thus mankind will have one more admonition that ‘the people perish for lack of knowledge ; ? and that the allevia- tion of the miseries, and the promotion of the welfare, of man must be sought, by those who will not lose their pains, in that diligent, patient, loving study of all the multitudinous aspects of Nature, the result of which constitute exact knowledge, or Science.” 8. «On the Relations of Penicillium, Torula, and Bacterium” (Address to the Biological Section of the Brit. Assoc., September 13, 1870. Report by E. Ray Lankester in the Q. J. Micros, Sci. New Series, x, 1870, pp. 355-62. Sci. Mem., iii, xxxvii, p. 601).—Here are detailed some of the results of investigations on certain lower forms of plant life (compare 7). Huxley’s atten- tion was directed to these forms, partly from a desire to get first-hand knowledge of types he intended to include in a course on practical biology, and partly by the re- searches of Dr. Bastian, in which bacteria were asserted to have been spontaneously generated. 1871. The School Board work of 1871, which has already been dealt with, naturally limited activity in other direc- tions, though there is still plenty to record. The most important event of the year was perhaps Huxley’s ac- ceptance of the Secretaryship of the Royal Society, which arduous post he held for the next ten years. Among the most important duties discharged during this period were those in connection with the Challenger committee. We find the usual variety of lectures delivered to all sort of audiences, and embracing a wide range of topics. The one on “ Administrative Nihilism” (Coll. Essays, i, PRACTICAL BIOLOGY III p. 251), given at the Midland Institute, Birmingham, on October 9, is of special interest, for it gives an account of the educational policy which Huxley had so strenu- ously urged upon the London School Board. It includes a defence of educational progress for the benefit of the masses, and recognizes that training of the intellect is not the only thing at which to aim :— “Thoughtfulness for others, generosity, modesty, and self- respect, are the qualities which make a real gentleman or lady, as distinguished from the veneered article, which commonly goes by that name.” Locke’s definition, ‘“‘ The end of Government is the good of mankind,” is accepted, and the conclusion reached that the Government is justified in undertaking to educate the people. Discourses at the Royal Institution (May 12 and 19) entitled “Berkeley on Vision,” and ‘Metaphysics of Sensation” (Coll. Essays, vi, 243) would seem to have been suggested by the recent appearance of Fraser’s edition of Berkeley’s works. The most important lecture development of the year, however, consisted in a summer course for teachers on Biology, with practical work, an entirely new departure. In this course he was assisted by E. Ray Lankester. It is relevant to mention here that from 1870 to 1875, Huxley was a member of a Royal Commission on Scientific Instruction and the Advancement of Science. An essay on ‘‘ Yeast” (Sci. Mem., iii, xxxvim1, p. 608. Coll. Essays, viii, p. 110), published in the Contemporary Review for December, is a part of the work on lower forms of life, to which Huxley had been devoting much attention (cf. pp. 109-10). It gives a very interesting his- torical account of the growth of our knowledge in regard to alcoholic fermentation. A quotation is given from 112. THOMAS HENRY HUXLEY Schwann (Mikroscopische Untersuchungen) embodying a view of this pioneer worker to the effect, “. , . that every cell of the living body exerts an influence on the matter which surrounds and permeates it, analogous to that which the Toru/a [i.e. yeast plant] exerts on the saccharine solution by which it is bathed. A wonderfully suggestive thought, opening up views of the nature of the chemical pro- cesses of the living body, which have hardly yet received all the development of which they are capable.” The doctrine of ‘internal secretions” would appear to be the modern expression of this epoch-making idea. The essay also dwells on the importance of the “germ theory,” with regard to infectious and contagious disease. An important article, entitled ‘‘ Mr. Darwin’s Critics,” was contributed to the Contemporary Review for November (Coll. Essays, ii, p. 120). This deals with Wallace’s Contributions to the Theory of Natural Selection, Mivart’s Genesis of Species, and a Quarterly Review notice of Darwin’s Descent of Man. Wallace denied that man could have been evolved by natural selection, while Mivart admitted its possibility for the bodily frame, The Quarterly reviewer was long afterwards publicly admitted to have been Bishop Wilberforce. Huxley’s essay follows Darwinism to its logical conclusion, and adopts the view that there has been a gradual evolution of mind. Mivart asserted the teach- ings of orthodox Catholic authorities to be evolutionary, citing more particularly the Jesuit writer, Father Suarez. Huxley definitely disproves this, for the authority in question. Writing to Darwin on this point, he says (Life, i, p. 364) :— ‘So I have come out in the new character of a defender of Catholic orthodoxy, and upset Mivart out of the mouth of his own prophet.” MANUAL ON VERTEBRATES 113 The estimate of Huxley’s mental powers formed by some of his friends is strikingly embodied in a remark Darwin, when expressing his appreciation of «‘ Mr. Dar- win’s Critics,” quotes from Hooker : “When I read Huxley, I feel quite infantile in intellect (Life, i, p. 365). The preparation of this defence of Darwin, and of the article on ‘‘ Administrative Nihilism” took up no small part of the brief summer holiday at St. Andrews, which was also trenched upon by the British Association (Edin- burgh Meeting) and other activities. Attempts, none too successful, at golf-playing, did not sufficiently compensate for over-pressure during the vacation, and a break-down in health took place at the end of the year. Mention must also be made of the Manual of the Anatomy of Vertebrated Animals, which appeared in 1871, and though never revised, is still (thirty-five years later) indispensable to the student of vertebrate anatomy. It differs profoundly from average text-books in that most of the contained matter is based either on the author’s own researches or his first-hand observation of facts. This year, too, Huxley, Roscoe, and Balfour Stewart undertook the joint editorship of a series of Science Primers for Messrs. Macmillan. CHAPTER XI EGYPT—-LORD RECTOR OF ABERDEEN UNIVERSITY— PRACTICAL BIOLOGY [1872-75]. A CONSIDERABLE part of 1872 was necessarily spent in the pursuit of health, for overwork and a variety of worries, including financial ones, had led to a recurrence of the old malady, dyspepsia, and a complete break-down resulted. The necessary means for meeting the ex- penses of a complete rest abroad were subscribed by eighteen friends, and Huxley was apprised by an affec- tionate and most delicately-worded letter from Darwin (Life, i, p. 366), that his banking account had been credited with the sum of 2000 guineas. On January 11, he left Southampton for Egypt, visiting Gibraltar on the way, partly for the purpose of investigating, on behalf of the Admiralty, the infestation of stored biscuits by the grubs of a small beetle (Ephestia elatella). ‘The source of infection was discovered, and a term put to the insects’ ravages. On February 1, Huxley reached Alexandria, and went up the Nile as far as Assouan. Of the effect of Egypt upon his mind, Mr. Leonard Huxley thus speaks (Life, i, pp. 369-70) :— ‘“‘ Egypt left a profound impression upon him. His artistic delight in it apart, the antiquities and geology of the country were a vivid illustration to his trained eye of the history of man and the influence upon him of the surroanding country, the link between geography and history.” Returning from Egypt by way of Italy, Catania, Naples, Pozzuoli, Pompeii, and Rome were visited, and 1g PRACTICAL BIOLOGY £15 an ascent made of Vesuvius. London was reached on April 6. Unfortunately the rest and change were of little permanent benefit. During this year Huxley’s department migrated from Jermyn Street to South Kensington, and, for the first time, he was able to give his ordinary students the benefit of practical instruction, on the same lines as those adopted for the summer class in 1871. Speaking of the method employed, Mr. Leonard Huxley says (Life, i, p- 376) :— “Tt involved the verification of every fact by each student, and was a training in scientific method even more than in scientific fact.”’ This may have been the aim of the work, but if “every fact” means all or most of those given in the lectures, the statement is very far from being correct. Every teacher of botany or zoology is fully aware that only a selection of leading facts can be verified by ele- mentary students. But, even so, the advance on current methods was a great one, and unanticipated in Britain, except by Rolleston at Oxford, and he, according to Professor Ray Lankester, had been influenced by Huxley’s advice, and fortunately had “the earlier opportunity of putting the method into practice.” The courses thus initiated were on the “type systém,” a series of average organisms being examined and dissected to illustrate the groups to which they belong. This method has profoundly influenced the teaching of Biology in this country, and fully justified Huxley’s expectation that it would ‘ grow into a big thing and bear great fruit.” Of late, however, the system has been somewhat discredited, since the practice of a number of teachers, following the arbitrary require- 116 THOMAS HENRY HUXLEY ments of various examiners, has been to make the subject a weary grind of disconnected facts, many of them of ex- ceedingly trivial kind. For some years the extraction of the minute ovaries of the earthworm was the goal of the student of elementary Biology. Although the “ pious founder” must not be blamed for the way in which his method has been perverted, yet he was accustomed to enter into somewhat full detail regarding the anatomy and physiology of the rabbit, thus limiting the time avail- able for the other types, and creating a wrong impression among the unintelligent. Huxley’s classes at South Kensington were made up of two varieties of student, those who paid, and those who were paid for by the Government, i.e., science teachers in training. The latter were by many regarded as of an inferior order, and had to attend every Saturday to receive their weekly allowance of twenty-five shillings (since reduced in amount) from the hands of a petty official, factory fashion. Some of the professors even put up two examination lists, thus emphasizing the gulf dividing the two castes. Opposed as he always was to snobbery in every form, Huxley made no such invidious distinc- tion, and the names of sheep and goats alike were associated in the same list. It has elsewhere been mentioned (cf pp. 56, 77), that Huxley sympathized with the movement for the higher education of women, and anticipated no ill effects from placing every facility in their way, but an incident of this year (1872) shows that he was opposed to “ mixed” classes in certain subjects. Miss Jex Blake, who was ‘furthering the cause of women medical students at Edin- burgh, had asked him to examine their male demonstrator in anatomy, with a view to his recognition by the Uni- versity Court. WOMEN MEDICAL STUDENTS 117 In a letter giving good reasons for declining to accede to this request, he expresses his sympathy with the aspirations of women in the direction of medicine, but adds :— «¢ Tas completely sympathize with those Professors of Anatomy, Physiology, and Obstetrics, who object to teach such subjects to mixed classes of young men and women brought together with- out any further evidence of moral and mental fitness for such association than the payment of their fees. In fact, with rare exceptions, I have refused to admit women to my own lectures on Comparative Anatomy for many years past. But I should not hesitate to teach anything I know to a class composed of women. . .’” (Life, i, p. 387). It greatly redounds to the credit of Scotland that Huxley was very early recognized and appreciated there. Of the four honorary doctorates conferred on him by British Universities, the order was—Edinburgh, 1866; Dublin, 1878; Cambridge, 1879; Oxford, 1885. In 1872, the students of Aberdeen elected him Lord Rector of their University. His address in that capacity was delivered in 1874, and will be dealt with later. The only scientific memoir that appeared in 1872 was in completion of his monumental work on fossil fishes, “British Fossils. Tlustrations of the Structure of Cross- opterygian Ganoids ”(Mem. Geol. Survey, U.K., Decade xu, 1872; Sci. Mem., Supply. Vol., m1, p. 68). It deals with Holophagus gulo. 1873. In 1873 Huxley’s health was fortunately pretty well established, largely as a result of a summer holiday spent in the Auvergne district. ‘This included not only exer- cise and change of scene, but also change of work in the 118 THOMAS HENRY HUXLEY form of geological and archeological observations, and a careful study of literature for and against the pseudo- miracles of Lourdes. His travelling companion was Hooker. One outcome of the holiday was the publication by the latter of observations on glaciation in central France (Nature, xiii, p. 31), though it afterwards turned out that the results had been anticipated by others. The trip ended in Switzerland and South Germany. Those who crave for personal details will be interested to know that during this tour Huxley consumed a reasonable number of cigars. Hooker had previously (1867) introduced him to cigarettes, as an antidote for gastric disturbance. A somewhat ardent devotion to “‘my Lady Nicotine” ultimately culminated in the pipe (1875). The practice, however, was primarily thera- peutic, for Hooker says (Life, i, p. 393, foot-note) :— “I have never blamed myself for the ‘teaching him’ to smoke, for the practice habitually palliated his distressing symptoms when nothing else did, nor can his chronic illness be attributed to the abuse of tobacco.” The present writer, however, does not propose to promote the sale of one or more brands, by mentioning them here. Among other fresh duties undertaken were those connected with his appointment as a Governor of Owens College, which institution was opened in the autumn. Much time was taken up in connection with the Royal Commission on Scientific Instruction, etc. Some of Huxley’s essays were collected and published this year under the title of Critiques and Addresses. Though very largely read this never attained the extreme popularity of Lay Sermons (cf. p. 105). An essay en- titled ‘‘ Problems of the Deep Sea” was put out in 1873 LORD RECTOR OF ABERDEEN 119 (Coll. Essays, viii, p. 37). It explained the aims of the Challenger expedition, which had started on December 21, 1872, and gave a popular account of the various kinds of apparatus employed. As a member of the Challenger Committee of the Royal Society, Huxley had had a great deal to do both with arranging the programme of the expedition, and laying down the methods to be employed. 1874. With health fairly well re-established, the work accomplished during 1874 was of increased amount. The most important event that took place in the early part of the year was the Rectorial Address on “ Univer- sities: Actual and Ideal,” given at Aberdeen (Coll. Essays, iii, p. 189).—This compares to their disadvan- tage — “‘,.. the host of pleasant, moneyed, well-bred young gentlemen, who do a little learning and much boating by Cam and Isis,” with “many a brave and frugal Scotch boy, spending his summer in hard manual labour, that he may have the privilege of wend- ing his way in autumn to this University, with a bag of oatmeal, ten pounds in his pocket, and his own stout heart to depend upon through the northern winter.” The contrast is perhaps a little overdone, and reminds one of the more recent utterance of a well-known noble- man, who described a newly-established University as adapted to ‘‘ the hard and even horny-handed workman,” at the first meeting of the Court of that University. The address describes the ideal University as one in which all subjects of study are impartially treated, and as to the student :— “. . , the very air he breathes should be charged with that enthusiasm for truth, that fanaticism of veracity, which is a 120 THOMAS HENRY HUXLEY greater possession than much learning; a nobler gift than the power of increasing knowledge; by so much greater and nobler than these, as the moral nature of man is greater than the intellectual ; for veracity is the heart of morality.” Then follows a plea for art and a scheme for the im- provement of medical education. It is suggested that the two first years be given to Anatomy, Physiology, Physio- logical Chemistry and Physics ; the fundamental principles of Chemistry, Physics, and Biology having been pre- viously acquired. Huxley notes with satisfaction the inclusion of Zoology as a compulsory subject in the Arts course in Aberdeen. This, however, is not now the case. The Address further advocates the establishment of a Faculty of Science in every University, sets forth the claims of research, touches on the question of exam- inations, and points out the necessity for properly organized secondary education. It is gratifying to find that Huxley was able, at Aber- deen, to do something towards bringing about the reforms in medical education which he advocated in his Rectorial Address. The second important address of the year (August 2), was upon “ Joseph Priestley” (Coll. Essays, iii, p. 1), given on the occasion of the presentation of a statue of Priestley to the town of Birmingham by Lord Derby. He speaks of Priestley as one of the men whose work helped to bring about the expansion of science, and the scientific spirit, which mark the nineteenth, as compared with the eighteenth, century :— “If we ask what is the deeper meaning of all these vast changes, I think there can be but one reply. They meant that reason has asserted and exercised her primacy over all provinces of human activity: that ecclesiastical authority has been relegated to its proper place; that the good of the governed has beea WOMEN MEDICAL STUDENTS 121 finally recognized as the end of government, and the complete responsibility of governors to the people as its means; and that the dependence of natural phenomena in general on the laws of action of what we call matter has become an axiom.” The British Association was held at Belfast this year, and on August 24 Huxley delivered an address ‘On the Hypothesis that Animals are Automata, and its History” (Coll. Essays, i, p. 199). This demonstrates that the foundations of neuro-physiology were laid down by Descartes, though the position that brutes are unconscious machines is discarded as untenable. It is worth noting that in this essay Huxley categorically denies the charges of fatalism, materialism, and atheism, made at various times against himself. The views upon women’s medical education, alluded to in connection with Miss Jex Blake’s letter of the previous year, were further elaborated and expressed in 1874. This lady had failed in the Edinburgh examina- tions, and Huxley pronounced adversely upon her papers when these were referred to him for report. The foilow- ing extract from the Times for July 8, 1874, clearly explains his position :— “As Miss Jex Blake may possibly think that my decision was influenced by prejudice against her cause, allow me to add that such prejudice as I labour under lies in the opposite direction. Without seeing any reason to believe that women are, on the average, so strong physically, intellectually, or morally, as men, I cannot shut my eyes to the fact that many women are much better endowed in all these respects than many men, and I am at a loss to understand on what grounds of justice or public policy a career which is open to the weakest and most foolish of the male sex should be forcibly closed to women of capacity. «© We have heard a great deal lately about the physical dis- abilities of women. Some of these alleged impediments, no doubt, are really inherent in their organization, but nine-tenths of them are artificial—the products of their modes of life. I 122 THOMAS HENRY HUXLEY believe that nothing would tend so effectually to get rid of these creations of idleness, weariness, and that ‘ over-stimulation of the emotions,’ which, in plainer-spoken days, used to be called wantonness, than a fair share of healthy work, directed towards a definite object, combined with an equally fair share of healthy play, during the years of adolescence; and those who are best acquainted with the requirements of an average medical practi- tioner will find it hardest to believe that the attempt to reach that standard is like to prove exhausting to an ordinarily intelligent and well-educated young woman.” One curious piece of work done in 1874 was the writ- ing of a report (dated January 27) on a spiritualistic séance attended, the conclusion being reached that this was an unmitigated fraud. He had investigated the subject in previous years. For some time Huxley, in conjunction with W. K. Parker, had been busily engaged in working at the structure of the skull, a subject in which he had long been interested (cf p. 40). The following scientific memoirs of 1874 were mostly on this subject. I. ‘On the Structure of the Skull and of the Heart of Menobranchus lateralis” (Proc. Zool. Soc., 1874, pp- 186-204. Read March 17, 1874. Sci. Mem., iv, 1, p. 1). 2. “Note on the Development of the Columella Auris in the Amphibia (Nature, xi, 1875, pp. 68-9. Read at the Brit. Assoc., Belfast, August 25, 1874, Sci. Mem., iv, Il, p. 23). 3. “Preliminary Note upon the Brain and Skull of Amphioxus lanceolatus” (Proc. Roy. Soc., xxiii, 1875, pp- 127-32. Received December 17, 1874. Sci. Menm., iv, 11, p. 26). 4. “On the Bearing of the Distribution of the Portio Dura upon the Morphology of the Skull” (Proc. Phil. Soc., Cambridge, ii, 1876, pp. 348-51. Read May 11, 1874. Sci. Mem., iv, tv, p. 32). ENCYCLOPEDIA BRITANNICA 123 5. “On the Classification of the Animal Kingdom” (J. Linn. Soc. (Zool.), xii, 1876, pp. 199-226. Read December 3, 1874. Sci. Mem., iv. v, p. 35). Huxley advised Professor Baynes, the general editor of the Encychpedia Britannica, about the apportionment of the biological articles to be included in the ninth edition, and himself wrote up Actinozoa, Amphibia, Animal Kingdom, Biology, and Evolution. ‘The prepara- tion of these articles began late in 1873 and went on intermittently till 1878, when that on Evolution was completed. After recommending a particular specialist as suitable for the task of writing an important article, Huxley adds,— “. . . if it had not been for the accident of being a pro- crastinating, impracticable ass, he could have been a distinguished man. But he is a sort of Balaam-Centaur, with the asinine stronger than the prophetic moiety’’ (Life, i, p. 452). The current system of supporting applications by means of testimonials would certainly be abandoned if all such documents were frankly conceived and epigram- matically written in this style. 1875 The earliest important event of 1875 was the delivery of an address at the Royal Institution on January 29, the subject being ‘‘ On the Recent Work of the Challenger Expedition, and its bearing on Geological Problems” (Proc. Roy. Inst., vii, 1875, pp. 354-7. Sci. Mem., iv, vi, p. 61. Coll. Essays, viii, p. 69).—This gives an account of the various deposits accumulating on the sea-floor, and seeks to explain the unfossiliferous nature 124 THOMAS HENRY HUXLEY of some geological strata by comparing them with the red clays characteristic of the deepest parts of the oceans. The absence of Prof. Wyville Thomson as chief naturalist to the Challenger expedition necessitated the appointment of deputies to carry on the work of his Edinburgh classes. For the summer session of 1875 Huxley’s services were secured, and he managed to review the entire animal kingdom in fifty-four lectures (May 3 to July 23), given to a record class of 353 students. In a letter to Tyndall (dated August 13, 1875) he says :— ‘*My work at Edinburgh got itself done very satisfactorily, and I cleared about £1000 by the transaction, being one of the few examples known of a Southern coming north and pillaging the Scots”’ (Life, i, p. 447). In the Life (pp. 36-7) of one of the pupils attending this particular class, the late Joseph Thomson, the follow- ing interesting impressions of Huxley as a teacher are given :— «©The experience of studying personally under Huxley was a privilege to which he had been looking forward with eager anticipation ; for he had already been fascinated with the charm of Huxley’s writings, and had received from them no small amount of mental stimulus. Nor were his expectations disap- pointed. But he found the work to be unexpectedly hard, and very soon he had the sense of panting to keep pace with the demands of the lecturer. It was not merely that the texture of scientific reasoning in the lectures was so closely knit,— although that was a very palpable fact—but the character of Huxley’s terminology was entirely strange to him. It met him on his weakest side, for it presupposed a knowledge of Greek (being little else than Greek compounds with English termina- tions), and of Greek he had none. ‘<¢ Fluxley’s usual lectures,’ he writes, ‘are something awful to listen to. One half of the class, which numbers about four hundred, have given up in despair from sheer inability to follow EDINBURGH LECTURES 125 him. The strain on the attention of each lecture is so great as to be equal to an ordinary day’s work. I feel quite exhausted after them. And then to master his language is something dreadful. But, with all these drawbacks, I would not miss them, even if they were ten times as difficult. They are some- thing glorious, sublime... . Huxley is still very difficult to follow, and I have been four times in his lectures completely stuck and utterly helpless. But he has given us eight or nine beautiful lectures on the frog.’ ”’ For comparison with the above, the writer can only offer his personal experience of one course of regular lectures (1879-80). These were perhaps less com- pressed than those given in Edinburgh, and in any case were perfectly easy to follow, though to reap full benefit from them a good deal of previous reading was necessary. Note-taking, however, was an exceedingly difficult matter, even in shorthand, owing to Huxley’s great fluency and his habit of illustrating the subject by means of rapid blackboard sketches, without ceasing to speak, Such terms as “ glorious” and “sublime” are somewhat out of place. <‘‘ Lucid” and “‘ incisive” would be nearer the mark. No particular knowledge of Greek was necessary in 1879, whatever may have been the case in 1875. For some years the anti-vivisectionists had been making their voices heard both in and out of season. Huxley among others had quite undeservedly earned the reputa- tion of being perfectly callous to the sufferings of animals employed for physiological experiment. As a matter of fact he was extremely tender-hearted where animals were concerned, and expressly refrained from entering upon investigations involving vivisection, But this was a very different matter from denying the necessity for expert research in directions where the benefit of mankind was involved. 126 THOMAS HENRY HUXLEY During 1875 the vivisection controversy culminated in the appointment of a ‘Royal Commission on the Practice of subjecting Live Animals to Experiments for Scientific Purposes.” In writing to the then Home Secretary (Mr. Cross) to express his willingness to serve, Huxley sufficiently defines his position in the matter :-— «If I can be of any service I shall be very glad to act on the Commission, sympathising as I do on the one hand with those who abhor cruelty to animals, and, on the other, with those who abhor the still greater cruelty to man which is involved in any attempt to arrest the progress of physiology and of rational medicine ”’ (Life, i, p. 439). The report of the Commission, presented in the early part of 1876, was decidedly unsatisfactory, and the legisla- tion which followed upon it was still more so. In 1875 the first edition appeared of 4 Course of Practical Instruction in Elementary Biology, in the prepara- tion of which the late Dr. H. N. Martin collaborated. Up to this time the only practical book available to the student was Rolleston’s Forms of Animal Life, which was not only expensive but of limited use for laboratory purposes, since it merely described the Oxford series of dissections, and gave no practical directions at all. “Huxley and Martin” was largely used for many years, and did yeoman service in advancing the cause of practical biology. Owing largely to its employment, the “type system” became firmly established as the recognized method of teaching biology in this country. Unfortunately, in course of time, it underwent a curious perversion, due to unintelligent teaching and still more unintelligent examining. A mass of minute detail gradu- ally became associated with the chosen types, the acquisi- tion of which prevented average students from grasping CROCODILES AND LUNG-FISHES 127 fundamental principles. A concrete instance of “not seeing the wood for the trees.” The three following scientific memoirs represent part of the work done during 1875, though the two last were not published till the following year :— 1. On Stagonolepis Robertsoni, and on the Evolu- tion of the Crocodilia” (Q. J. Geol. Soc., xxxi, 1875, pp. 423-38. Sci. Mem., iv, vu, p. 66).—This famous memoir propounds an evolutionary classification of croco- dilian reptiles, including the ancient extinct type named. The hinder openings of the nasal cavities are placed far back in the throat in recent crocodiles, and so disposed that the mouth can be kept open under water without danger of suffocation, an obvious adaptation to the aquatic habit. The way in which this arrangement has gradually evolved is here set forth. 2. ‘Contributions to Morphology. Ichthyopsida. No. 1. On Ceratodus Forsteri, with Observations on the Classification of Fishes” (Proc. Zool. Soc., 1876, pp. 24-59. Received January 4, 1875. Sci. Mem., iv, vil, p. 84).—The form in question is the Australian Lung-fish, one of the few surviving members of a once widely distributed and dominant marine group, which have been saved from extinction by taking to a life in fresh water, where the struggle for existence is less severe. The classificatory part of the memoir, largely based on the characters of the skull and fins, is distinctly of epoch-making character, and has had to be reckoned with in all subsequent attempts to place the systematics of fishes on a sound footing. 3. “On the Position of the Anterior Nasal Apertures in Lepidosiren” (op. cit., pp. 180-1. Received January 7, 1876. Sci. Mem., iv, 1x, p. 125).—This is a note on the South American Lung-fish. ’ CHAPTER XIII VISIT TO AMERICA [1876-77]. One of the earlier efforts of 1876 was a Friday Evening Discourse, delivered on January 28, at the Royal Institution «‘On the Border Territory between the Animal and the Vegetable Kingdoms,” afterwards published in Macmillan’s Magazine (Sci. Mem., iv, x1, p. 145. Coll. Essays, viii, p- 162). Here the conclusion is reached that,— “the difference between animal and plant is one of degree rather than kind, and that the problem whether, in a given case, an organism is an animal or a plant, may be essentially insoluble.”’ A second lecture ‘‘ On the Teleology and Morphology of the Hand,” given at Glasgow on February 15, was never published in its original form, but is of special interest because it emphasizes the Darwinian doctrine that teleology and evolution are so far from being irre- concilable that the former, broadly expressed, is a necessary corollary of the latter. The old teleology, as more particularly set forth in Paley’s Natural Theohgy (one of Huxley’s favourite Sunday books as a boy), held that every organism and organ was separately created for a special purpose, finding this the only explanation of the adaptation of structure to function everywhere to be found. Bell’s famous Bridgewater Treatise on the human hand develops this view with reference to a particular instance, and no doubt suggested to Huxley his choice of subject for the Glasgow lecture. The new teleology explains the adaptation of structure 128 INTEREST IN FICTION 129 to function as the result of evolution, and renders in- telligible many things, such as vestigial organs and im- perfect adaptations, which were simply ignored by its forerunner. While not demanding a theistic standpoint, it is not inconsistent with this. As in the previous year a course of lectures was given at Edinburgh during the Summer Session, and one or two incidents relating to this time deserve notice. Ina home letter (dated May 8, Life, i, p. 458), we find a list of the light and other literature taken North as a set-off against work, and note that, unlike Darwin, Huxley re- tained an interest in fiction :— ‘‘T have been getting through an enormous quantity of read- ing, some tough monographs that I brought with me, the first volume of Forster’s Life of Swift, Goodsir’s Life, and a couple of novels of George Sand, with a trifle of Paul Heyse. You should read George Sand’s Césarine Dietrich and La Mare au Diable that I have just finished. She is bigger than George Eliot, more flexible, a more thorough artist. It is a queer thing by the way, that I have never read Consuelo, I shall get it here. When I come back from my lecture I like to rest for an hour or two over a good story. It freshens me wonderfully.” It would have been decidedly entertaining to see Huxley on May 25, sitting beside the Lord High Com- missioner at the General Assembly. His report of the proceedings is a model of brevity :— se... I heard an ecclesiastical row about whether a certain church should be allowed to have a cover with IHS on the Communion Table or not. After three hours’ discussion the IHSers were beaten ”’ (Life, i, p. 458). The social side of the temporary residence in Edinburgh at this time left many pleasant memories, especially of the numerous visits to Dr. (afterwards Sir John) Skelton at I 130 THOMAS HENRY HUXLEY the Hermitage of Braid, which laid the foundation of a warm and long friendship. The great event of 1876 was the American visit, Huxley’s ‘second honeymoon,” in the course of which he once more met (after a separation of thirty years), his favourite sister Lizzie (Mrs. Scott), whose love and en- couragement had done so much for him in early years. The occasion of the visit was the delivery of the opening address at the Johns Hopkins University in Baltimore. New York was reached on August 5, and two characteristic remarks made on first sight of the city have been recorded by Mr. Smalley (London correspondent of the New York Tribune). In response to a question as to the names of two buildings :— “TI told him the Tribune and the Western Union Telegraph buildings. *‘ Ah,’ he said, ¢ that is interesting ; that is American. In the Old World the first things you see as you approach a great city are steeples ; here you see, first, centres of intelligence.’ Next to those the tug-boats seemed to attract him as they tore fiercely up and down and across the bay. He looked long at them and finally said, «If I were not a man I think I should like to be a tug.’ They seemed to him the condensation and complete expression of the energy and force in which he delighted (Life, i, p. 461). Huxley was naturally intensely interested in Prof. Marsh’s collection of fossils from the wonderfully rich strata of the Western Territories, which demonstrated the American origin of the horse, and proved of the first importance in placing the doctrine of evolution on a firm palzontological basis. The geological history of the horse was to be the subject of one of the New York lectures, and the study of the Yale specimens necessitated important alterations in what had been written for this purpose. Marsh thus describes Huxley’s attitude in the matter :— AMERICAN VISIT 131 ‘* He then informed me that all was new to him, and that my facts demonstrated the evolution of the horse beyond question, and for the first time indicated the direct line of descent of an existing animal, With the generosity of true greatness, he gave up his own opinions in the face of new truth, and took my con- clusions as the basis of his famous New York lecture on the horse” (Life, i, p. 462). The American trip included a week at Niagara, where the falls gave Huxley enormous pleasure, not merely as a spectacle, but also as a standard instance of a particular sort of geological action. The scientific enjoyment derived from the study of the latter only served to heighten the artistic impression. On September 12, his ‘‘ Address on University Education” was delivered without notes, at the opening of the Johns Hopkins University, Baltimore (Coll. Essays, iii, p. 235). The ‘‘educational ladder” so much talked of in these later days, is here advocated :— “The primary school and the university are the alpha and omega of education.” Secondary schools, if established, should be true inter- mediaries, — “, . . keeping on the wide track of general culture, and not sacrificing one branch of knowledge for another.” The university student should be subjected to an initial test at the end of his first term. Within the limits of a prescribed curriculum there should be a free choice of subjects. Half the fortune of the pious founder had been devoted to establishing a hospital in Baltimore, and hence some part of this address is devoted to the question of medical education, from which Huxley suggests that zoology, botany and materia medica should be excluded, 132 THOMAS HENRY HUXLEY the elements of the two first being a fitting part of an earlier stage. The Johns Hopkins University was established with special reference to the encouragement of research, re- garding which we read :— « But so sure as it is that men live not by bread, but by ideas, so sure is it that the future of the world lies in the hands of those who are able to carry the interpretation of nature a step further than their predecessors ; so certain is it that the highest function of a university is to seek out those men, cherish them, and give their ability to serve their kind full play.” The waste of money on mere architecture is deprecated, a plea entered for reasonable payment of the staff, and that these with other experts should be properly repre- sented on the governing body, if only in the interest of good and rational appointments to the professoriate. The address concludes with the expression of a firm belief in the future of America,— «*, . . but the one condition of success, your sole safeguard, is the moral worth and intellectual clearness of the individual citizen.”’ The three lectures on Evolution were delivered at New York on September 18, 20 and 22 (Coll. Essays, iv, p- 46). The first deals with ‘‘The Three Hypotheses respecting the History of Nature,” ze., that of perpetual sameness, the special creation hypothesis, and the doctrine of evolution. This leads on to the second lecture on “©The Hypothesis of Evolution: the Neutral and the Favourable Evidence,” and this again to the third lecture on *‘ The Demonstrative Evidence of Evolution,” illustrated by the special case of the horse, for which the American strata furnish such valuable materials. The results derived from a study of these were embodied in a lecture RECEPTION IN AMERICA 133 given at the London Institution on December 4, en- titled, ‘On Recent Additions to the Knowledge of the Pedigree of the Horse.” Huxley left New York on September 23, and his visit to America must be regarded as marking the com- mencement of a new stage in his career. Mr. Leonard Huxley thus summarizes the nature of his reception and its import :— “Certainly the people of the States gave him an enthusiastic welcome; his writings had made him known far and wide ; as the manager of the Californian department of the Philadelphia Exhibition told him, the very miners of California read his books over their camp fires; and his visit was so far like a royal progress, that unless he entered a city disguised under the name of Jones or Smith, he was liable not merely to be interviewed, but to be called upon to ‘ address a few words’ to the citizens. . . . His reception in America may be said to emphasize his definite establishment in the first rank of English thinkers. It was a signal testimony to the wide extent of his influence, hardly sus- pected, indeed, by himself; an influence due above all to the fact that he did not allow his studies to stand apart from the moving problems of existence, but brought the new and re- generating ideas into contact with life at every point, and that his championship of the new doctrises had at the same time been a championship of freedom and sincerity in thought and word against shams and self-deceptions of every kind. It was not so much the preacher of new doctrines who was welcomed, as the apostle of veracity—not so much the teacher of science as the teacher of men”’ (Life, i, p. 460). The lectures, etc., delivered in the States were published in 1877 under the title of American Addresses. In this volume was also included a lecture ‘‘On the Study of Biology ” (Sci. Mem., iv, xiv, p. 248. Coll. Essays, iii, p. 262), given at South Kensington on December 16 (1876) in connection with the Loan Collection of Scien- tific Apparatus. It is pointed out that the idea of estab- lishing a science of life (biology), bringing together the 134 THOMAS HENRY HUXLEY disciplines dealing with organisms and their functions, occurred independently to three contemporaries, Bichat, Lamarck and Treviranus. Lamarck first used the word “ Biologie,” and Treviranus wrote a Biologie in six volumes (1802-22). The reasons for studying biology are next set forth. Its utility is obvious from the fact that it, “, .. tends to give right ideas, which are essential to the foundation of right practice, and to remove wrong ideas, which are the no less essential foundations and fertile mothers of every description of error in practice.” Another reason for the study is to be found in the con- sideration that man is not an isolated and peculiar being, but one of a series of organisms, displaying unity in structure and function. The important bearings of the subject on infectious disease, and its value to agriculture are finally pointed out. As to the method of studying biology, the type system, as adopted at South Kensington, is advocated. The im- portance of rationally arranged museums is also emphasized. The needs of the general public in this respect are,— «©, . . not met by constructing a sort of happy hunting-ground of miles of glass cases; and, under the pretence of exhibiting everything, putting the maximum amount of obstacle in the way of those who wish properly to see anything.” As to the time when biology may best be studied, it is held that this should form part of an ordinary school training. Human anatomy and physiology, and also botany, are pointed out as the most suitable branches of the subject for the purpose. Special classes, with practical work, might well be established in secondary schools. Six lectures to working-men ‘‘On the Evidence as to the Origin of Existing Vertebrate Animals” were given SCOTTISH UNIVERSITIES — 135 in the Royal School of Mines this year (Nature, xiii, 1876, pp. 388-9, 410-12, 429-30, 467-9, 514-6; xiv, 1876, pp. 33-4. Sci. Mem., iv, xu, p. 163). The recent advances made in paleontology are here lucidly explained :— “The accurate information obtained in this department of science has put the fact of evolution beyond a doubt ; formerly, the great reproach of the theory was, that no support was lent to it by the geological history of living things; now, whatever happens, the fact remains that the hypothesis is founded on the firm basis of palzontological evidence.” During 1876, too, a memoir was published ‘On the Nature of the Craniofacial Apparatus of Petromyzon” (J. Anat. and Physiol., x, 1876, pp. 412-29. Sci. Mem., iv, x, p. 128).—This deals with the skeleton of the head in the lamprey, the complicated elements of which are described with the most painstaking accuracy. “The interpretation given to some of them, however, has not met with general acceptance. 1877. A good deal of time was taken up during 1877 in furthering educational interests of various kinds. Huxley’s work as a member of the Scottish Universities Commission necessitated three visits to Edinburgh, and the intimate acquaintance he had gained of the Scottish system would seem to have made a favourable impression as to its worth, in strong contrast with his consistently uncompromising attitude in regard to those supposedly effete centres of learning, Oxford and Cambridge. At any rate his eldest son was entered as a student at St. Andrews in the fall of the year; though he subsequently went up to Oxford. 136 THOMAS HENRY HUXLEY The legislation which had been the outcome of the report of the Vivisection Commission suggested a lecture on ‘Elementary Instruction in Physiology,” de- livered at the Anthropological Conference on May 22 (Coll. Essays, iii, p. 294). Here animal physiology is spoken of as an essential part of domestic economy, and Huxley’s supposed desire to introduce vivisection into school teaching disclaimed. ‘The infliction of pain on animals for the purposes of gain or sport is strongly deprecated. For some time the necessity for promoting a proper system of technical education had been strongly borne in upon some of the more enlightened members of the community, the Clothworkers’ Company and the Society of Arts co-operating to this end. In July of this year a committee of the City Companies applied to Huxley, among others, for a statement of his opinions regarding the aims and methods of technical education. The fol- lowing paragraph, taken from the extensive report he supplied, goes to the root of the matter: — “Tt appears to me that if every person who is engaged in an industry had access to instruction in the scientific principles on which that industry is based; in the mode of applying these principles to practice; in the actual use of the means and appli- ances employed ; in the language of the people who know as much about the matter as we do ourselves ; and lastly, in the art of keeping accounts, Technical Education would have done all that can be required of it.”’ An address on ‘“‘ Technical Education,” given at the Working Men’s Club and Institute, on December 1, gives further expression to Huxley’s ideas on the subject (Coll. Essays, iii, p. 404). Since an anatomist may be regarded as a handicraftsman, he excuses himself for venturing into the only educational domain with which TECHNICAL EDUCATION 137 he had so far had nothing to do. The address then proceeds to consider what preliminary instruction an anatomist should receive. There should be good ele- mentary education, including the elements of physical science, especially physics and chemistry. The power of reading Latin, French, and German should be acquired. Some attention ought to be paid to drawing, and physical training is an essential. The dangers of attempting too much are depicted. Children subjected to educational over-pressure are,— “,. . . conceited all the forenoon of life, and stupid all its afternoon.”’ Speaking of the preparatory education of the handi- craftsman, Huxley says that this should have nothing “technical” about it, for, “the workshop is the only real school for a handicraft.” Intellectual gear is not the only equipment of value :— “ Activity, probity, knowledge of men, ready mother-wit, supplemented by a good knowledge of the general principle in- volved in his business, are the making of a good foreman.” Provision should be made for giving lads of real ability a chance. He continued for a number of years to take an active interest in technical education, and his warm advocacy of the movement had much to do with the establishment of the Cowper Street Schools, and the Central Institution of the City and Guilds of London, which took place in 1881. The University of Cambridge conferred the degree of LL.D. (Aonoris causé) upon Charles Darwin in November, and at the Philosophical Club dinner, held the same evening, Huxley paid an eloquent tribute to him (in his 138 THOMAS HENRY HUXLEY absence). The tardiness of Cambridge in recognizing one of her greatest sons was delicately hinted at, and though in a letter to Darwin (dated November 21) de- liberate sneering is denied, a milder form of sarcasm is admitted :— «There was only a little touch of the whip at starting, and it was so tied round with ribbons that it took them some time to find out where the flick had hit”’ (Life, i, p. 479). If the following extract from Huxley’s notes of the speech fairly represents the utterance, the ‘ribbons ” would distinctly add to the unpleasantness of the ‘‘ flick.” It was, however, an after-dinner speech :— “Mr. Darwin’s work had fully earned the distinction you have conferred upon him four-and-twenty years ago; but I doubt not that he would have been found in that circumstance an exemplification of the wise foresight of his revered intel- lectual mother. Instead of offering her honours when they ran a chance of being crushed beneath the accumulated marks of approbation of the whole civilized world, the University has waited until the trophy was finished, and has crowned the edifice with the delicate wreath of academic appreciation”? (Life, i, p. 480). Examples have already been given to show that if Huxley’s unrivalled power of scathing sarcasm was often manifested, generosity and kindness of heart were even more characteristic. Mr. Leonard Huxley records a good instance for 1877 (Life, i, p. 482) :— «A German scientific worker in England, whom we will call H., had fallen into distress, and applied to him for help, asking if some work could not be put in his way. Huxley could think of nothing immediate but to suggest some lessons in German literature to his children, though in fact they were well provided for with a German governess. . . .”” An unnamed donor, however, furnished the necessary CHARACTERISTIC GENEROSITY 139 money, in response to a request from Huxley, who says in a letter to his wife :— “Tt came inthe nick of time, as H. came an hour or two after it arrived, and with many apologies told me he was quite penniless. The poor old fellow was quite overcome when I told him of how matters stood, and it was characteristic that as soon as he got his breath again, he wanted to know when he would begin teaching the children.” Besides those already-mentioned, lectures were given this year on ‘‘Starfishes and their Allies” (March 7, Royal Institution) ; «‘ The Geological History of Birds” (June 7, Zoological: Gardens); and ‘Belemnites” (December 17, London Institution). The article on “ Evolution” (Coll. Essays, ii, p. 187), for the 9th edition of the Encyclpadia Britannica was completed this year, but did not appear till the following. There is evolution of the individual (ontogeny), and evolution of animal groups (phylogeny). The study of the latter, as based on observation followed by specula- tion, does not go further back than the seventeenth century, and Harvey’s work serves as a point of departure. The subject matter is grouped under eight headings :— 1. Cartesianism, a mechanical theory of the physical universe, Descartes, Spinoza, and Leibnitz, De Maillet, Buffon, Erasmus Darwin, Goethe, Lamarck, Treviranus, Charles Darwin, Wallace, Spencer, and Haeckel. 2. Gradations of Structure among Living Beings, Leeuwenhoek and Swammerdam, Lamarck, Cuvier and Von Baer. 3. Analogy between Ontogeny and Phylogeny, Meckel. 4. Morphology, or Form and Structure; Variations on a Common Plan, Belon and Wolff. 5. Vestigial or Rudimentary Organs, 140 THOMAS HENRY HUXLEY 6. Influence of a Changing Environment in Modifying Organisms. Climate, Station and Hybridization recog- nized before the time of Treviranus. Use and Disuse, advanced as factors by Lamarck. Ultimately Darwin’s theory of Natural Selection. 7. Geographical Distribution, Darwin and Wallace. 8. Geological Succession, Darwin and Wallace. Riitimeyer, Kowalewsky, Marsh, and Huxley. Work on pedigrees of Mammals and Crocodiles. The strongest evidence in favour of Evolution afforded by 7 and 8. Two important books also appeared in 1877, i.e, Physiography and The Anatomy of Invertebrated Animals. The former embodies the preliminary lectures which Huxley had given for some sessions as an introduction to his regular course (see p. 37), and of which the Thames basin furnished the main theme. This work had an ex- tensive circulation for many years, and a judiciously edited revised edition has recently been put. before the public. With the intention, apparently, of encouraging the teaching of general principles as laid down by Huxley, the Science and Art Department added “ Physiography ” to their list of subjects, the first examination being held in May 1878. The result was unfortunate, for the syllabus was conceived in a singularly unscientific spirit, and consisted of an extraordinary aggregate of disjecta membra. The subject, indeed, was about as unscientific as the ‘¢ General Elementary Science,” of which so much has been heard during late years. But we must re- member that it belongs to the time when any degree of any British University qualified its possessor to earn Government grants in any science or pseudo-science subject, from Pure Mathematics and Naval Construction to the Principles of Agriculture. ANATOMY OF INVERTEBRATES 141 The Anatomy of Invertebrated Animals shares many of the characteristics of the sister work on Vertebrates, published in 1871, and embodies a large amount of Huxley’s own original researches. It does not, however, reach the same high level of excellence. One scientific memoir has to be mentioned for 1877— “The Crocodilian Remains found in the Elgin Sand- stones, with Remarks on the Ichnites [i.e., fossil foot- prints] of Cummingstone” (Mem. Geol. Survey U.K., Monograph III, 1877. Sci. Mem., iv, xu, p. 188). —This deals chiefly with the remains of the primitive extinct crocodile Stagonolepis (cf p. 127). CHAPTER XIV HARVEY AND HUME—CRAYFISHES—DUBLIN AND CAMBRIDGE DOCTORATES [1878-79]. Durinec the early part of 1878, immediately after the marriage of his eldest daughter, Huxley’s work was greatly interfered with by an outbreak of diphtheria in his family, which occasioned the most serious anxiety. His then demonstrator, the late Prof. T. J. Parker, writes of this :— “T never saw a man more crushed than he was during the dangerous illness of one of his daughters, and he told me that, having then to make an after-dinner speech, he broke down for the first time in his life, and for one painful moment forgot where he was and what he had to say.” To which his private assistant at the time, the late Prof. G. B. Howes, adds :— «When, after two days, he looked in at the laboratory, his dejected countenance and tired expression betokened only too plainly the intense anxiety he had undergone” (Life, i, P- 492). While the above exemplifies Huxley’s devotion as a father, the visit of Prof. Marsh to England just after this trying time, illustrates his character as a friend. Of this Marsh himself writes as follows (Recollections, p. 6) :— «How kind Huxley was to every one who could claim his friendship, I have good cause to know. Of the many instances 142 4 ae ania Ages cask: CHARACTER AS A FRIEND 143 which occur to me, one will suffice. One evening in London, at a grand annual reception of the Royal Academy, where celebrities of every rank were present, Huxley said to me, ‘When I was in America, you showed me every extinct animal that I had read about, or even dreamt of. Now, if there is a single living lion in all Great Britain that you wish to see, 1 will show him to you in five minutes?’ He kept his promise, and before the reception was over, I had met many of the most noted men in England, and from that evening, I can date a large number of acquaintances, who have made my subsequent visits to that country an ever-increasing pleasure ”’ (Life, i, p. 494). Huxley’s anxiety at this time about the failing health of Prof. W. K. Clifford affords further evidence, were such necessary, of his sterling character as a friend. Another personal matter of the year was the confer- ment of the degree of LL.D. (Aomoris causd) of the University of Dublin, which took place during the meeting of the British Association, where he had delivered an address to the section on Anthropology. The subject was ‘‘ Informal Remarks on the Conclusions of Anthropology,” the central point being that Man is a legitimate subject of scientific study, and that the possi- bility of his origin by a process of evolution must be admitted (Nature, xviii, 1878, pp. 445-8. Sci. Mem., iv, XV, p. 265). In a letter to his eldest daughter later in the year (December 7), upon the Afghan war, Huxley shows that absorbing scientific and educational work did not preclude a lively interest in political events and the wel- fare of the empire :— «Tam strong for justice as any one can be, but it is real justice, not sham conventional justice which the sentimentalists howl for. « At this present time real justice requires that the power of 144 THOMAS HENRY HUXLEY England should be used to maintain order and introduce civiliza- tion wherever that power extends. «The Afghans are a pack of disorderly, treacherous, blood- thirsty thieves and caterans, who should never have been allowed to escape from the heavy hand we laid upon them, after the massacre of twenty thousand of our men, women (and) children in the Khoord Cabul Pass thirty years ago. “‘ We have let them be, and the consequence is they now lend themselves to the Russians, and are ready to stir up disorder and undo all the good we have been doing in India for the last generation. “‘ They are to India exactly what the Highlanders of Scot- land were to the Lowlanders before 1745; and we have just as much right to deal with them in the same way. ‘*T am of opinion that our Indian Empire is a curse to us. But so long as we make up our minds to hold it, we must also make up our minds to do those things which are needful to hold it effectually, and in the long-run it will be found that so doing is real justice both for ourselves, our subject population, and the Afghans themselves” (Life, i, p. 489). As regards scientific work, 1878 must be described as a Harvey, Hume and Crayfish year. The first direction of activity was dictated by the fact that April 1 was the tercentenary of Harvey’s birth. On January 25, Huxley lectured at the Royal Institution on ‘“ William Harvey” (Fortnightly Review, New Ser., xxiii, 1878, pp. 167-90. Sci. Mem., iv, xvii, p. 319). In this lecture Harvey’s scientific attitude is shown to be independent of the Baconian philosophy, and occasion is taken to make an attack on the extreme views of anti-vivisectionists. A speech on Harvey was also delivered at the Memorial Meeting, held on July 18, by the College of Physicians. A book on Hume took the form of a volume of the English Men of Letters Series, written at the request of the General Editor, Mr. (now the Right Hon.) John Morley. Huxley’s strong philosophical predilections here find full expression. A few quotations will at the LIFE OF HUME 145 same time illustrate his philosophical attitude, and his power as a writer, The Preface (dated January 1894) to the sixth volume of the Collected Essays, most of which is a reprint of the Hume, begins with an eloquent tribute to Descartes and Socrates, but Plato is severely handled :— ‘‘The Platonic philosophy is probably the grandest example of the unscientific use of the imagination extant; and it would be hard to estimate the amount of detriment to clear thinking effected, directly and indirectly, by the theory of ideas, on the one hand, and by the unfortunate doctrine of the baseness of matter, on the other.” Berkeley and Hume are then mentioned as the greatest philosophical reformers since Descartes, and the following advice is given to those who wish to acquire a sound knowledge of philosophy, but do not desire merely “*to discourse fluently and learnedly about philosophical questions . . .”:— “Tf . . . you are animated by the much rarer desire for real knowledge ; if you want to get a clear conception of the deepest problems set before the intellect of man, there is no need, so far as I can see, for you to go beyond the limits of the English tongue. Indeed, if you are pressed for time, three English authors will suffice; namely, Berkeley, Hume, and Hobbes. “If you will lay your minds alongside the works of these great writers—not with the view of merely ascertaining their opinions, still less for the purpose of indolently resting upon their authority, but to the end of seeing for yourselves how far what each says has its foundation in right reason—you will have had as much sound philosophical training as is good for any one but an expert. And you will have had the further advantage of becoming familiar with the manner in which three of the greatest masters of the English language have handled that noble instrument of thought.” A vigorous sketch of Hume’s Life occupies the first K 146 THOMAS HENRY HUXLEY part of the book, while the second and larger part is taken up by Hume’s philosophy. The following passages near the end of the former, having reference to Hume’s self-selected place of burial on the Calton Hill, are among the finest of their kind that Huxley ever penned :— << From the summit of this hill, there is a prospect unequalled by any to be seen from the midst of a great city. Westward lies the Forth, and beyond it, dimly blue, the far-away Highland hills; eastward, rise the bold contours of Arthur’s Seat and the rugged crags of the Castle rock, with the gray Old Town of Edinburgh; while, far below, from a maze of crowded thoroughfares, the hoarse murmur of the toil of a polity of energetic men is borne upon the ear. At times a man may be as solitary here as in a veritable wilderness; and may meditate upon the epitome of nature and of man—the kingdoms of this world—-spread out before him. “ Surely, there is a fitness in the choice of this last resting- place by the philosopher and historian, who saw so clearly that these two kingdoms form but one realm, governed by uniform laws and alike based on impenetrable darkness and eternal silence ; and faithful to the last to that profound veracity which was the secret of his philosophic greatness, he ordered that the simple Roman tomb which marks his grave should bear no inscription but DAVID HUME, BORN I71]. DIED 1776. Leaving it to posterity to add the rest. “It was by the desire and at the suggestion of my friend, the Editor of this Series, that I undertook to attempt to help posterity in the difficult business of knowing what to add to Hume’s epitaph; and I might, with justice, throw upon him the responsibility of my apparent presumption in occupying a place among the men of letters, who are engaged with him, in their proper function of writing about English Men of Letters. «‘That to which succeeding generations have made, are making, and will make, continual additions, however, is Hume’s fame as a philosopher; and, though I know that my plea will PHILOSOPHY OF HUME 147 add to my offence in some quarters, I must plead, in extenua- tion of my audacity, that philosophy lies in the province ot science, and not in that of letters,” To demonstrate the scientific nature of Hume’s philo- sophy would appear to be the chief aim of the sequel of Huxley’s book. ‘The view stated in the last sentence of the above quotation is expanded in Chap. I. ‘On the Object and Scope of Philosophy ” :— ‘“
