HUNTER, JOHN (1728-1793), as physiologist and surgeon combined, unrivalled in the annals of medicine, born February 13,1 1728, at Long Calderwood, in the parish of East Kilbride, Lanarkshire, was the youngest of the ten children of John and Agnes Hunter. His father, who died October 1741,2 aged 78, was descended from the old Ayshire family of Hunter of Hunterston, and his mother was the daughter of a Mr Paul, treasurer of Glasgow. Hunter is said to have made but little progress at school, being averse to its restraints and pursuits, and fond of country amusements. When seventeen years old he repaired to Glasgow, where he for a short time assisted his brother-in-law, Mr Buchanan, a cabinetmaker, who had involved himself in pecuniary difficulties. Being desirous at length of some settled occupation, he obtained from his brother William permission to aid, under Mr Symonds, in making dissections in his anatomical school, then the most celebrated in London, intending, should he be unsuccessful there, to enter the army. He arrived accordingly in the metropolis in September 1748, about a fortnight before the commencement of his brothers autumnal course of lectures. After succeeding beyond expectation with the dissection of the muscles of an arm, he was entrusted with a similar part injected, and from the excellence of his second essay Dr Hunter predicted that he would become a good anatomist. Seemingly John Hunter had hitherto received no instruction in preparation for the special course of life upon which he had entered. His brother, with whom he was now intimately associated, was one of the most brilliant exponents of medical science, and enjoyed the society of the best cultured men of the age ; but that it was through this circumstance that, as stated by R.A. Stafford,3 "he was taught to think," and that his mind, as has been surmised, had previous to his coming to London been "idle, heedless, and aimless," can hardly be concluded in the face of what the future revealed of the practical and inquiring turn and the originality of his mental disposition. Rather we, may assumed, with B.B. Cooper,4 that Hunter was naturally gifted with powers of mind which rendered him to some extent independent of training required by less extraordinary intellects. Dr J. Ridge,5 speaking of Hunters permitted truancy from the grammar school, argues that early tuition and attainments, at least of the kind imparted, being inconsistent with a natural education of the senses, are not favourable to the production of extraordinary genius. Hunters power of estimating what was worth doing, and what could be done, is by Dr Moxon 6 ascribed in part to his being "a man who had a free youth, not over-taught, nor over-strained;" and, if it be true that "the early part of life, the school-time, has long been spent, and is spent, in pursuits which minister but little to the culture of the mind, or to the communication and reception of knowledge useful to any class of society in proportion to the time to the time consumed," it is possible that his dislike to scholastic exercises may have served to protect Hunter which made him pre-eminent as a teacher, namely, the power of perceiving the relation of numerous individual facts as illustrations of general principles.
Hard-working, and singularly patient and skilful in dissection, Hunter had by his second winter in London acquired sufficient anatomical knowledge to be entrusted with the charge of his brothers practical class, with the members of which, as also with the resurrection men, he was a universal favourite. In the summer months of 1749-50, at Chelsea Military Hospital, he attended the lectures and operations of Cheselden, on whose retirement in the following year he became a surgeons pupil at St Bartholomews, where Pott was one of the senior surgeons. In the summer of 1752 he visited Scotland. Home and, following him, Ottley state that Hunter began in 1754 to assist his brother as his partner in lecturing ; according, however, to the European Magazine for 1782, the office of lecturer was offered to Hunter by his brother in 1758, but declined by him on account of the "insuperable embarrassments and objections" which he felt to speaking in public. In 1754 he became a surgeons pupil at St Georges Hospital, where he was appointed house-surgeon in 1756.8 During the period of his connexion with Dr Hunters school he, in addition to other labours, solved the problem of the descent of the testis in the foetus, traced the ramifications of the nasal and olfactory nerves within the nose, experimentally tested the question whether veins could act as absorbents, studied the formation of pus, and the nature of the placental circulation, and with his brother earned the chief merit of practically proving the function and importance of the lymphatics in the animal economy. On June 5, 1755,9 he was induced to enter as a gentleman commoner at St Marys Hall, Oxford, but his true instincts would not permit him, to use his own expression, "to stuff Latin and Greek at the university." Some three and thirty years later he thus significantly wrote of an opponent:"Jesse Foot accuses me of not understanding the dead languages ; but I could teach him that on the dead body which he never knew in any language dead or living."10 Doubtless, however, linguistic studies would have served to correct in him what was perhaps a natural defecta difficulty in the presentation of abstract ideas which was not wholly attributable to the novelty of his doctrines.
An attack of inflammation of the lungs in the spring of 1759, apparently caused by overwork, having produced symptoms threatening consumption, by which the promising medical career of his brother James had been cut short, Hunter, with a view to residence abroad for a season, obtained from Mr Adair in October 1760 the appointment of staff-surgeon in Hudgson and Keppels expedition to Belleisle. With this he sailed in 1761. In the following year he served with the English forces on the frontier of Portugal. Whilst with the army he acquired the extensive knowledge of gunshot wounds, embodied in his important treatise on that subject, published in 1794, in which, amongst other matters of moment, he insists on the rejection of the indiscriminate practice of dilating with the knife followed almost universally by surgeons of his time. When not engaged in the active duties of his profession, he occupied himself with physiological and other scientific researches. Thus, in 1761, off Belleisle, the conditions of

In the buttery book for 1755 at St Marys Hall his admission is thus noted : "Die Junii 510 to 1755 Admissus est Johannes Hunter superioris ordinis Commensalis." Hunter apparently left Oxford after less than two months residence, as the last entry in the buttery book with charges for battels against his name is on July 25, 1755.

the coagulation of the blood were among the subjects of his inquiries.1 Later, on land, he continued the study of human anatomy, and arranged his notes and memoranda on inflammation ; he also ascertained by experiment that digestion does not take place in snakes and lizards during hibernation, and observed that enforced vigorous movement at that season proves fatal to such animals, the waste so occasioned not being compensated, whence he drew the inference that, in the diminution of the power of a part attendant on mortification, resort to stimulants which increase action without giving real strength is inadvisable.2 A MS. catalogue by Hunter, probably written soon after his return from Portugal, shows that he had already made a collection of about two hundred specimens of natural and morbid structures.
On arriving in England early in 1763, Hunter, having retired from the army on half-pay, took a house in Golden Square, and commenced the career of a London surgeon. Most of the metropolitan practice at the time was held by Pott, C. Hawkins, Sharpe, Warner, Adair, and Tomkins ; and Hunter sought to eke out his at first slender income by teaching practical anatomy and operative surgery to a private class. He leisure was devoted to the study of comparative anatomy, to procure subjects for which he obtained the refusal of animals dying in the Tower menagerie and in various travelling zoological collections. In connexion with his rupture of a tendo Achillis,3 in 1767, he performed on dogs several experiments which, with the illustrations in his museum of the reunion of such structures after divisions, laid the foundation of the modern practices of cutting through tendous for the relief of distorted and contracted joints. In the same year he was made a fellow of the Royal Society. His first contribution to the Philosophical Transactions, with the exception of a supplement to a paper by J. Ellis in the volume for 1766, was an essay on post-mortem digestion of the stomach, written at the request of Sir J. Pringle, and read June 18, 1772 in which he first correctly explained that phenomenon as a result of the action of the gastric juice.4 Hunter, on December 9, 1768, was elected a surgeon to St Georges Hospital, and, soon after, a member of the Corporation of Surgeons. He now began to take house-pupils. Among these were Edward Jenner, who came to him in 1770, and until the time of Hunters death corresponded with him on the most intimate and affectionate terms, W.Guy, Kingston, Dr Physick of Philadelphia, and Everard Home, his brother in-law. Mr Lynn and Sir Carlisle, though not inmates of his house, frequent visitors there. His pupils at St Georges included Abernethy, Cline, James Earle, and Astley Cooper. From the high reputation in their profession which these one and attained, some estimate may be formed of the weight and value of Hunters personal influence and teaching. In 1770 he settled in Jermyn Street, in the house which his brother William had previously occupied ; and in July 1771 he married Anne, the eldest daughter of Mr Robert Home, surgeon to Burgoynes regiment of light-horse.5
From 1772 till his death Hunter resided during autumn at a house built by him at Earls Court, Brompton, where most of his biological researches were carried on. There he kept for the purpose of study and experiment the fishes lizards, blackbirds, hedgehogs, and other animals sent him from time to time by Jenner, tame pheasants and patridges, at least one eagle, toads, silkworms, and many more creatures obtained from every quarter of the globe. Bess he had under observation in his conservatory for upwards of twenty years ; hornets and wasps were also dilegently studied by him. On two occasions his life was in risk from his petsonce in wrestling with a young bull, and again when he fearlessly took back to their dens two leopards which had broken loose among his dogs. Choosing intuitively the only true method of philosophical discovery, Hunter, ever cautions of confounding fact and hypothesis, besought of nature the truth through the medium of manifold experiments and observations. "he had never read Bacon," says Babington, "but his mode of studying nature was as strictly Baconian as if he had."6 To Jenner, who had offered a conjectural explanation of a phenomenon, he wirtes, August 2, 1775 : "I think your solution is just ; but why think? Why not tray the experiment? Repeat all the experiments upon hedgehog7 as soon as you receive this, and they will give you the solution." Perhaps no man busily engaged in professional practice has ever conducted so many physiological and pathological investigations in the animal world as Hunter ; and yet it was with him an axiom "that experiments should not be often repeated which tend merely to establish a principle already known and admitted, but that the next step should be the application of the principle to useful purpose" ("Anim. Cecon.," Works, iv. 86). During fifteen years he kept a flock of geese simply in order to acquaint himself with the development of birds in eggs, with reference to which he remarked"It would almost appears that this mode of propagation was intended for investigation." In his toxicological and other researches, in which his experience had led him to believe that the effects of noxious drugs are nearly similar in the brute creation and in man he had already, in 1780, as he states, "poisoned some thousands of animals."8
By inserting shot at definite distances in the leg-bones of young pigs, and also by feeding them with madder, by which all fresh osseous deposits are tinged,9 Hunter obtained evidence that bones increase in size, not by the intercalation of new amongst old particles, as had been

(3) According to Hunter, as quoted in Palmers edition of his lectures, p. 437, the accident was "after dancing, and after a violent fit of the cramp;" Clift, however, who says he probably never danced, believed that he met with the accident "in getting up from the disecting table after being cramped by long sitting" (see W. Lawrence, Hunt. Orat., 1834, p. 64).
(4) The subjects and dates of his subsequent papers in the Transactions, the titles of which give little notion of the richness of their contents, are as follows:The torpedo, 1773 ; air-receptacles in birds, and Gillardo trout, 1774 ; the Gymnotus electricus, and the production of heat by animals and vegetables (supplemented in 1777), 1775 ; the recovery of people apparently drowned, 1776 ; the free martin, 1779 ; the communication of smallpox to the foetus in utero, and the occurrence of male plumage in old hen pheasants, 1780 ; the organ of hearing in fishes, 1782; the organ of hearing in fishes, 1782 ; the anatomy of a "new marine animal" described by Home, 1785 ; the specific identity of the wolf, jackel, and dog (supplemented in 1789), the effect on fertility of extirpation of one ovarium, and the structure and economy of whales, 1787 ; observations on bees, 1793 ; and some remarkable caves in Bayreuth and fossil bones found therein, 1794. With these may be included a paper by Home, from materials supplied by Hunter, on certain horny excrescences of the human body.
(5) Mrs Hunter died January 7, 1821, in Holles Street, Cavendish Square, London, in her seventy-ninth year. She was a handsome and accomplished woman, and well fulfilled the social duties of her position. The words for Haydns English canzonets were supplied by her, and were mostly original poems ;of these the lines beginning "My mother music, among the best known. (See R. Nares in Gent.

imagined by Duhamel, but by means of additions to their extremities and circumference, excess of calcareous tissue being removed by the absorbents. Some of his most extraordinary experiments were to illustrate the relation of strength of constitution to sex. He exchanged the spurs on a young cock and a young pullet, and found that on the former the transplanted structure grew to a fair size, on the latter but little ; whereas a spur from one leg of a cock transferred to its comb, a part well supplied with blood, grew more than twice as fast as that left on the other leg. Another experiment of his, which required many trials for success, was the engrafting of a human incisor on the comb of a cock.1 The uniting of parts of different animals when brought into contact he attributed to the production of adhesive instead of suppurative inflammation, owing to their possession of " the simple living principle." 2 The effects of habbit upon structure were illustrated by Hunters observation that in a sea-gull which he had brought to feed on barley the muscular parietes of the gizzard became greatly thickened. A similar phenomenon was noticed by him in the case of other carnivorous birds fed on a vegetable diet.
It was in 1772 that Hunter, in order effectually to gauge the extent of his own knowledge, and also to correctly express his views, which had been repeatedly misstated or ascribed to others, commenced his lectures on the theory and practice of surgery, at first delivered free to his pupils and a few friends, but subsequent to 1774 on the usual terms, four guineas. Though Pott, indeed, had perceived terms, four guineas. Though Pott, indeed, had perceived that the only true system of surgery is that which most closely accords with the curative efforts of nature, a rational pathology can hardly be said to have had at this time any existence ; and it was generally assumed that a knowledge of anatomy alone was a sufficient foundation for the study of surgery. Hunter, unlike his contemporaries, to most of whom his philosophic habit of thought was a mystery of cases, and modes of treatment, sought the reason for each phenomenon that came under his notice. The principles of surgery, he maintained, are not less necessary to be understood than the principles of other sciences ; unless, indeed, the surgeon should wish to resemble "the Chinese philosopher whose knowledge consisted only in facts." In that case the science must remain unimproved until fresh facts arise. Too much attention, he remarked, cannot be paid to facts ; yet a multitude of facts overcrowd the memory without advantage if they do not lead us to establish principles, by an acquaintance with which latterly comprised eighty-six lectures, delivered on alternate evenings between the hours of seven and eight, lasted from October to April. Some teacher of his time were content to dismiss he subjects of anatomy and surgery in a course of only six weeks duration. The task of lecturing is said to have been to Hunter so formidable that at the commencement of each course he was obliged to take half a drachm of laudanum. His class was usually small, and never exceeded thirty. Among its members at various times were Abernethy, Carlisle, Chevalier, Cline, Coleman, Astley Cooper, Home, Lynn, and Macartney. Hunter was deficient in the gifts of a good extempore speaker, being in this respect a remarkable contrast to his brother William and he read his lectures, seldom raising his eyes from the manuscript. His manner with his auditory is stated to have been embrassed and awkward, or as Adams puts it (Obs. On Morbid Pois., Pois., p. 272), "frequently ungraceful," and his language always unadorned ; but that his "expressions for the explaining of his new theories rendered his lectures often unintelligible" is scarcely evident in his pupils notes still extant. His own and others errors and fallacies were exposed with equal freedom in his teaching. Occasionally he would tell his pupils, "You had better not write down that observation, for very like I shall think differently next year ;" and once to a question of Colemans he replied, "Never ask me what I have said or what I have written ; but, if you will ask me what my present opinions are, I will tell you." He was always much gratified when, in the conversations that he encouraged his hearers to hold with him at the end of his lectures, he found that what he said was understood and appreciated.
In January 1776 Hunter was appointed surgeon-extra-ordinary to the king. He commenced in the same year his Croonian lectures on muscular motion, continued annually, except in 1777, till 1782 : they were never published by him, being in his opinion too incomplete. In 1778 appeared the second part of his Treatise on the Natural History of the Human Teeth, the first part of which was published in 1771. It was in the waste of the dental alveoli and of the fangs of shedding teeth that in 175455, as he tells us, he received his first hint of the use of the absorbents. Abernethy (Phys. Lect., p. 196) relates that Hunter, being once asked how he could suppose it possible for absorbents to do such things as he attributed to them, replied, "Nay, I know not, unless they possess powers similar to those which a caterpillar exerts when feeding on a leaf." Hunter in 1780 read before the Royal Society a paper in which he laid claim to have been the first to make out the nature of the utero-placental circulation. His brother William, who had five years previously described the same in his Anatomy of the Gravid Uterus, thereupon wrote to the Society attributing to himself this honour. John Hunter in a rejoinder to his brothers letter, dated February 17, 1780, reiterated his former statement, viz., that his former statement, viz., that his discovery, on the evening of the day in 1754 that he had made it in a specimen injected by a Dr Mackenzie, had been communicated by him to Dr Hunter. Thus arose an estrangement between the two Hunters, which continued until the time of Williams last illness when his brother obtained permission to visit him.
In 1783 Hunter was elected a member of the Royal Society of Medicine and of the Royal Academy of Surgery at Paris, and took part in the formation of "A Society for the Improvement of Medical and Chirurgical Knowledge."3 It appears from a letter by Hunter that in latter part of 1783 he, with Jenner, had the subject of colour-blindness under consideration. As in that year the lease of his premises in Jermyn Street was to expire, he purchased the twenty-four years leasehold of two houses, the one on the east of side Leicester Square, the other in Castle Street, with intervening ground. Between the houses he built in 178385, at an expense of above £3000, a museum for his anatomical and other collections. These by 1782 had cost him £10,000, and contained preparations of numerous specimens presented by Sir Joseph Banks, the Honourable C. Greville, and Mr Walsh. The new edifice consisted of a hall 52 feet long by 28 feet wide, and lighted from the top, with a gallery all round, and having beneath it a lecture

theatre, and a room used subsequently for the meetings of the Lycaeum Medicum, a society instituted by Hunter and Fordyce. In April 1785 Hunters collctions were removed into it under the superintendence of Home and Bell,1 and another assistant, André. Among the foreigners of distinction that inspected the museum, which was now shown by Hunter twice a year,in October to medical men, and Scarpa. In the acquisition of subjects for his varied biological investigations and of specimens for his museum, expense was a matter of small moment with Hunter. Thus at one time he endeavoured, at his own cost, to obtain information respecting the Cetacea by sending out a surgeon to the North in a Greenland whaler. He is said, moreover, to have given, in June 1783, no less than £500 for the body of OBrien, or Byrne, the Irish giant, whose skeleton, 7 feet 7 inches high, is so conspicuous an object in the museum of the College of Surgeons of London.2
Hunter, who in the spring of 1769-72 has suffered from gout, in spring 1773 from spasm apparently in the pyloric region, accompanied by failure of the hearts action (Ottley, Life, p.44), and in 1777 from vertigo with symptoms of angina pectoris, had in 1783 another attack of the last mentioned complaint, to which he was henceforward subject when under anxiety or excitement of mind.
In May 1785,3 chiefly to oblige Sharp the engravers, Hunter consented to have his portrait taken by Sir Joshua Reynolds. He proved a bad sitter, and Reynolds made but little satisfactory progress, till one day Hunter, while resting his somewhat upraised head on his left hand, fell into a profound reverieone of those waking dreams, seemingly, which in his lectures he has so well described, when "the body loses the consciousness of its own existence."4 The painted had now before him the man he would fain depict, and, turning his canvas upside down, he sketched out the admirable portrait which, since most skilfully restored by Mr H. Farrar, is in the possession of the Royal College of Surgeons. A copy of the same, by Jackson, acquired from Lady Bell, is to be seen at the National Portrait Gallery in South Kensington. St Marys Hall, Oxford, also possesses a copy. Sharps engraving of the original, published in 1788, is one of the finest of his productions. The volumes seen in Reynoldss picture are a portion of the unpublished records of anatomical researches left by Hunter at his death, which, with other manuscripts, Sir Everard Home in 1812 removed from his museum, and eventually, in order, it has been supposed, to keep secret the source of many of his papers in the Philosophical Transactions, and of facts mentioned in his lectures, committed to the flames.5
Among the subjects of Hunters physiological investigations in 1785 was the mode f growth of deers antlers. As he possessed the privilege of making experiments on the deer in Richmond Park, he in July of that year had a buck there caught and thrown, and tied one of its external carotid arteries. He observed that the antler which obtained its blood supply therefrom, then half-grown, became in consequence cold to the touch. Hunter debated with himself whether it would be shed in due time, or be longer retained than ordinary. To his surprise he found on re-examining the antler a week or two later, when the wound around the ligatured artery was healed, that it had regained its warmth, and was still increasing in size. Had, then, his operation been in some way defective? To determined this question, the buck was killed and sent to Leicester Fields. On examination Hunter ascertained that the external carotid had been duly tied, but that certain small branches of the artery above and below the ligature had enlarged, and by their anastomoses had restored the blood supply of the growing part. Thus it was evident that under "the stimulus of necessity," to use a phrase of the experimeter, the smaller arterial channels are capable of rapid increase in dimensions to perform the offices of the larger.6 It happened that, in the ensuing December, there lay in one of the wards of St Georges Hospital a patient of Hunters admitted for popliteal aneuris. The disease must soon prove fatal unless by some means arrested. Should the surgeon, following the usual and commonly fatal method of treatment, cut down upon the tumour, and, after tying the artery above and below it, evacuate its contents? Or should he adopt the procedure, deemed by Pott generally advisable, of amputating the limb above it? It was Hunters aim in his practice, even if he could not dispense with the necessity, at least to diminish the severity of operations, which he considered were an acknowledgement of the imperfection of the art of healing, and compared to "the acts of the armed savage, who attempts to get that by force which a civilized man would get by stratagem." Since, he argued, the experiment with the buck had shown that collateral vessels are capable of continuing the circulation when passage through a main trunk is arrested, why should he not, in his aneurism case, leaving absorbents to deal with the contents of the tumour, tie the artery in the sound parts, where it is tied in amputation, and preserve the limb? Acting upon this idea, he ligatured his patients femoral artery in the lower part of its course in the thigh, in the fibrous sheath enclosing the space since known as "Hunters canal."7 The leg was found, some hours after the operation, to have acquired a temperature even above the normal.8 At the end of January 1786, that is, in six weeks time, the patient was well enough to be able to leave the hospital. Thus it was that Hunter inaugurated an operation which has been the means of preserving to hundreds life with integrity of limban operation which, as the Italian Assalini, who saw it first performed, testifies, "excited the greatest wonder,

(2) OBrien, dreading dissection by Hunter, has shortly before his death arranged with several of his countrymen that his corpse should be conveyed by them to the sea, and sunk in deep water ; but his undertaker, who entered into a pecuniary compact with the great anatomist, managed that while the escort was drinking at a certain stage on the march seawards, the coffin should be locked up in a barn. There some men he bad concealed speedily substituted an equivalent weight of paving-stones for the body, which was at night forwarded to Hunter, and by him taken in his carriage to Earls Court, and, to avoid risk of a discovery, immediately after suitable division boiled to obtain the bones.

and awakened the attention of all the surgeons in Europe."
Early in 1786 Hunter published his Treatise on the Venereal Disease, which, like some of his previous writings, was printed in his own house. Without the aid of the booksellers, 1000 copies of it were sold within a twelvemonth. Although certain views therein expressed with regard to the relationship of syphilis have been proved erroneous, the work is a valuable compendium of observations of cases and modes of treatment (cf. Hilton, Hunt. Orat., p. 40) Towards the end of the year appeared his Observations one certain parts of the Animal Ceconomy, which, besides the more important of his contributions to the Philosophical Transactions, contains nine papers on various subjects. By The death of Mr Middleton in 1786, Hunter became duputy surgeon-general to the army ; his appointment as surgeon-general and as inspector-general of hospitals followed in 1790, on the death of Mr Adair. In 1787 he received the Royal Societys Copley medal as a testimony to the importance of his discoveries in natural history, and was also elected a member of the American Philosophical Society. On account of the increase in his practice and his impaired health, he now obtained the services of Home as his assistant at St Georges Hospital. The death of Pott in December 1788 secured to Hunter the undisputed title of the first surgeon in England. He resigned to Home, in 1792, the delivery of his surgical lectures, in order to devote himself more fully to the completion of his Treatise on the Blood, Inflammation, and Gunshot Wounds, which was published by his executors in 1794. In this, his masterpiece, the applicable to physiology to practice is especially noticeable. Certain experiments described in the first part, pp. 62-64, which demonstrate that arterialization of the blood in respiration takes place by a process of diffusion of "pure air" or "vital air" (i.e., oxygen) through membrane, were made so early as the summer of 1755.
Hunter in 1792 announced to his colleagues at St Georges, who, he considered, neglected the proper instruction of the students under their charge, his intention no longer to divide with them the fees which he received for his hospital pupils. Against this innovation, however, the governors of the hospital decided in March 1793. Subsequently, by a committee of their appointing, a code of rules respecting pupils was promulgated, one clause of which, probably directed against an occasional practice of Hunters, stipulated that no person should be admitted as a student of the hospital without certificates that he had been educated for the medical profession. In the autumn two young Scotchmen, ignorant of the new rule, came up to town and applied to Hunter for admission as his pupils at St Georges. Hunter explained to them how he was situated, but promised to advance their request at the next board meeting at the hospital on the 16th October. On that day, having finished a difficult piece of dissection, he went down to breakfast in excellent spirits and in his usual health. After making a professional call, he attended the board meeting. There the interruption of attended the board meeting. There the interruption of his remarks in behalf of his applicants by a flat contradiction from a colleague brought on one of the old spasmodic heart attacks ; he ceased speaking, and retired into the arms of Dr Robertson, one of the hospital physicians. After an hour had been spent in vain attempts to restore animation, his body was conveyed to his house in a sedan chair.1 Thus, in his sixty-fifth year, and in the height of his mental activity, died John Hunter, "whose range of thought nature alone could fill, and to whom, as to but few among all mankind, had been given wisdom to interpret the dark sayings of nature. His remains were interred privately on October 22, 1793, in the vaults of St Martins in the Fields. Thence, on March 28, 1859, through the instrumentality of Mr Frank Buckland, they were removed to About Islips chapel in Westminster Abbey, to be finally deposited in the grave in the north aisle of the nave, close to the resting-place of Ben Jonson.
Hunter was of about medium height, strongly built, and high-shouldered and short -necked. He had an open countenance, and large features, eyes light-blue or grey, eyebrows prominent, and hair reddish-yellow in youth, later white, and worn curled behind ; and he dressed plainly and neatly. He rose at or before six, dissected till nine (his breakfast hour), received patients from half-past nine till twelve, at least during the latter part of his life, and saw his outdoor and hospital patients till about four, when he dined, taking, according to Home, as at other meals in the twenty years preceding his death, no wine. After dinner he slept an hour ; he then superintended experiments read or prepared his lectures, and made, usually by means of an amanuensis, records of the days dissections. "I never could understand," says Clift, "how Mr Hunter obtained rest : when I left him at midnight, it was with a lamp fresh trimmed for further study, and with the usual appointment to meet him again at six in the morning." Mr H. Leigh Thomas records2 that, on his first arrival in London, having by desire called on Hunter at five oclock in the morning he found him already busily engaged in the dissection of insects. Rigidly economical of time, Hunter was always at work, and always he had in view regret that men must die at all. To his museum he gave a very large share of his attention, being fearful lest the ordering of it should be incomplete at his death, and knowing of none who could continue his work for him. "When I am dead," said he one day to Dr Garthshore, "you will not soon meet with another John Hunter." At the time of his death he had anatomized certainly over 500 different species of animals, some of repeatedly, and had made numerous dissections of plants. The manuscript works by him appropriated and destroyed by Home, among which were his eighty-six surgical lectures, all in full, are stated to have been "literally a cartload"; and many pages of his records were written by Clift under his directions "at least half a dozen times over, with corrections and transpositions almost without end."
To Hunter, as he himself observed, to think was a delight. His mind was framed for systematic investigation, and hence, perhaps, arose the fatigue which, more particularly during the last ten years of his life, the desultory conversation of a mixed company would occasion him.3 "My mind is like a bee-hive," was a remark of his to Abernethy, "a simile which struck me," says that writer, "on account of its correctness ; for, in the midst of buzz and apparent confusion, there was great order, regularity of structure, and abundant food, collected with incessant industry from the choicest stores of nature."4 Hunter was generally, though cheerfully, taciturn, and many a mornings labour with Clift was passed with scarcely a word of discourse. When, however, he spokeas while resting himself, and standing upright from his dissection after stooping for hours as if nailed to the object under investigationhe evinced both shrewdness and wit. In conversation his words were well chosen, and his remarks often wonderfully forcible and pointed; and, when so disposed, he could put things in a very ludicrous point of view. He articulated slowly, and in consultation gave his opinion much as if lecturing, the enunciation of his not seldom novel doctrines being prefaced by some introductory illustration or history. A stranger to artifice and flattery, and open and unceremonious or even blunt in speech, he readily communicated what he knew and thought, and thus did not always inspire other with a higher opinion of their personal consequence. "We are but beginning to learn our profession," he would tell hid friends ; and he was wont to say that he was conscious of no peculiar talent, but that, if he had promoted professional knowledge, it seemed to him to have arisen chiefly from his disposition to distrust opinions, and to examine every subject for himself. What views of his he confidently offered for acceptance were such as he believed to have a solid foundation in facts ; and the blind enunciation by his fellow-practitioners of time-honoured errors vexed
(1) The record of Hunters death in the St James Chronicle for October 15-17, 1793, p. 4, col. 4, make no allusion to the immediate cause of Hunters death, but gives the following statement:"JOHN HUNTER.This eminent Surgeon and valuable man was suddenly taken ill, yesterday, in the Council-room of St Georges Hospital. After receiving the assistance which could be afforded by two Physicians and a Surgeon, he was removed in a close chair to his house, in Leicester Fields, where he expired about two oclock." Examination of the heart revealed disease involving the pericardium, endocardium, and arteries, the coronary arteries in particular showing ossific change.

his mind, which was naturally susceptible, and was rendered the more so by excess of exertion, with repeatedly the additional strain of bodily disease. "I know, I know," said he to Abernethy, "I am but a pigmy in knowledge, yet I feel as a giant when compared with these men." The charges that his language was frequently coarse, and that swearing was with him a habit, as with many of his contemporaries and successors, have been indignantly rebutted by Clift.1 Leigh Thomas describes the impression left by his first early morning interview with Hunter as "a mingled feeling of profound respect, surprise, and admiration ;" and by his assistant, pupils and all with whom he had lived on intimate terms, he was both loved and venerated. His temper, Home states, was very warm and impatient, and when irritated not easily soothed. The hasty but not altogether illogical of his anger when refused the postmortem examination of a child, the victim of some obscure malady, in the words, "Then, sir, I heartily hope that yourself and all your family may all your friends, may die of the same disease, and that family, nay all your friends, may die of the same disease, and that no one may be able to afford any assistance," is in amusing contrast with the acknowledged benevolence of his character. To the kindness of his disposition, his fondness for animals, his aversion to operations, his thoughtful and self-sacrificing attention to his patients, and especially his zeal to help forward struggling practitioners and others in any want abundantly testify. "Every man," said he, "should be an economist, for if he has ever more money than his wants require he can assist the poor." In a letter of his, introducing a patient to his brother William, we read: "He has no money, and you have plenty, so that you are well met." Pecuniary means he valued no further then they enabled him to promote his researches ; and to the poor, to non-beneficed clergymen, professional authors and artists his services were rendered without remuneration. His yearly income in 1763-74 was never £1000; it exceeded that sum in 1778, for several years before his death was £5000, and at the time of the event had reached above £6000. All his earnings not required for domestic expenses were, during the last ten years of his life, devoted to the improvement of his museum ; and his property, this excepted, was found on his decease to be barely sufficient to pay his debts. By his contemporaries generally Hunter was respected as a master of the art and science of anatomy, and as a cautious and trustworthy if not an elegant or very dexterous operator. Few, however, perceived the drift of his biological researches. Although it was admitted, even by Foot,2 that the idea after which his unique museum had been formednamely, that of morphology as the only true basis of a systematic zoological classificationwas entirely his own, yet his investigations into the structure of the lower orders of animals were regarded as, after all, works of unprofitable curiosity. One surgeon, of no inconsiderable repute, is said to have ventured the remark that Mr Hunters preparations were "just as valuable as so many pigs pettitoes ;"3 and the president of the Royal Society, Sir Joseph Banks, writing in 1796, plainly expressed his disbelief as to the collection being "an object of importance to the general study of natural history, or indeed to any branch of science except to that of medicine." It was "without the solace of sympathy or encouragement of approbation, without collateral assistance,"4 and careless of achieving fame-for the held that "no man ever was a great man who wanted to be one"that Hunter laboured to perfect his designs, and established the science of comparative anatomy, and principles which, however neglected in his life-time, became the ground-work of all medical study and teaching.
In accordance with the directions given by Hunter in his will, his collection was offered for purchase to the British Government. But the prime minister, Mr Pitt, on being asked to consider the matter, exclaimed: "What! Buy preparations! Why, I have not money enough to purchase gunpowder." He, however, consented to the bestowal of a portion of the kings bounty for a couple of years on Mrs Hunter and her two surviving children. In 1796 Lord Auckland undertook to urge upon the Government that advisability of according the collection, and on June 13, 1799, parliament voted £15,000 for this purpose. Its custodianship, after refusal by the College of Physicians, was unanimously accepted by the Corporation of Surgeons on the terms proposed. These were in briefthat the collection be open four hours in the forenoon, two days every week, for the inspection and consultation of the fellows of the College of Physicians, the members of the Company of Surgeons, and persons properly introduced by them, a catalogue, of the preparations and an official to explain it being at those times always at hand ; that a course of not less than twenty-four lectures5on comparative anatomy and other subjects illustrated by the collection be given every year by some member of the Company ; and that the preparations be kept in good preservation at the expense of the Corporation, and be subject to the superintendence of a board of sixteen trustees.6 The fulfillment of these conditions was rendered possible by the receipt of fees for examinations and diplomas, under the charter by which, in 1800, the Corporation was constituted the Royal College of Surgeons. A board of curators was in that year appointed by the council of the college to provide for the management of the museum and the preparation of catalogues. In 1806 the collection was placed in temporary quarters in Lincolns Inn Fields, and the sum of £15,000 was voted by parliament for the erection of a proper and commodious building for its preservation and extension. This was followed by a grant of £12,500 in 1807. The collection was removed in 1812 to the new museum, and opened to visitors in 1813. The greater part of the present edifice was built in 1835, at an expense to the college of about £40,000; and the combined Hunterian and collegiate collections having been rearranged in what are now termed the western and middle museums, were in 1836 made accessible to the public. The erection of the eastern museum in 1852, on premises in Portugal Street bought in 1847 for £16,000, and cost £25,000, of which parliament granted £15,000; it was opened in 1855.
Hunters collection was estimated to contain 13,682 specimens, viz., in the physiological department, 3745 in spirit, 995 osteological, 617 dry, 1968 zoologicaltotal 7295 ; and in the pathological, 1084 in spirit, 625 dry (including bones), 536 calculi and concretions, 218 monsters and malformations, and 215 microscopictotal 2678 ; and 3709 fossils. Since its acquisition by the college, it has been greatly increased, notably by presentations from Sir William Blizard (1811) and Sir S. L. Hammick (1851), and by purchase of specimens in the possession of Sir A. Lever (1806), Messrs Joshua Brooke (1828), Heaviside (1829), Langstaff, South (1835), Howship, Taunton (1841), Liston (1842), and Walker (1843), Sir Astley Cooper (1843), and Dr Barnard Davis (Jan. 1880). The histological collection, of which he 215 Hunterian specimens are the nucleus is the result chiefly of the labours of Professor Quekett, and purchases from Dr Tweedy Tood, My Nasmyth, and Professor Lenhossek, and contained in July 1880 upwards of 12,000 specimens. The library, the formation of which commenced in 1801, consisted in July 1880 of 37,668 vols., comprising 14,882 separate works, and 39,021 tracts, pamphlets, essays, theses, and reports.7 Mr William Clift, whom, on February 14, 1792, Hunter received into his house to train as an assistant in his museum,8 had the exclusive charge of the collection from the date of its owners death to that of its purchase by the state. During this period, with two gallons of spirit meted out occasionally, and the pittance of 7s. a week for his own support out of the limited funds at the disposal of Hunters executors, he contrived to maintain the whole in good condition. He was conservator of the museum, as stated on the pedestral of his bust there, from 1800 to 1849. From 1825 to 1832 he was assisted by his son, William Home Clift. Professor Richard Owen held the office of assistant-conservator in 1832-35, and of consevator in 1836-55, and Professor J.T. Quekett that of assistant conservator in 1843-51, and of conservator from 1852 till his death in 1861, when he was succeeded by Professor William Henry Flower.
The scope of Hunters labours may be defined as the explication of the various phases of life in organized structures, both animal and vegetable, from the simplest to the most highly differentiated. By him, therefore, comparative anatomy was employed, not in subservience to the classification of living forms, as by Cuvier, but as a means of gaining insight into the principle animating and producing these forms, by virtue of which he perceived that, however different in form and faculty, they were all allied to himself. In what does life consist? Is a question which in his writings he frequently considers, and which seems to have been ever present in his mind. Life, he taught, was a principle independent of structure, most tenaciously held by the least highly organized beings but capable of readier destruction as a whole, as, e.g., by deprivation of heat or by plain, in young than in old animals. In life he beheld an agency working under the control of law and exercising its functions in various modes and degrees. He perceived it, as Abernethy observes, to be "a great chemist," a power capable of manufacturing a variety of substances into one kind of generally distributed nutriment, and of furnishing from this a still greater variety of dissimilar substances. Like Harvey, who terms it the anima vegetiva, he regarded it as a principle of self-preservation which keeps the body from dissolution. Life is shown, said he, in renovation and action ; but, although facilitated in its working by renovation and action ; but, although facilitated in its working by mechanical causes, it can exist without action, as in an egg new-laid or undergoing incubation. It is not simply a regulator of temperature ; it is a principle which resists cold, conferring on the structures which it endows the capacity of passing some degrees below the freezing-point of ordinary inanimate matter without suffering congelation. Hunter found, in short, that there exists in animals a latent heat of life, set free in the process of death (see Treatise on

(9) How clearly he held this view is seen in his remark (Treatise on the Blood, p. 28, cf. p. 46) that, as the coagulating lymph of the blood is probably common to all animals, whereas the red corpuscles are not, we must suppose the lymph to be the essential part o the fluid. Hunter was the first to discover that the blood of the embryos of red-blooded animals is at first colourless, resembling that of invertebrates. (See Owen, Preface to vol. iv. of Works. P. xiii.)
the Blood, p. 80). Thus he observed that sap is removed from trees froze at 32º Fahr., but within them might be fluid even at 15º; that a living snail placed in a freezing mixture acquired first a temperature of 28º, and afterwards of 32º ere it froze ; and that, whereas a dead egg congealed immediately at 32º, a living egg did so only when its temperature had risen to that point after a previous fall to 29_º. The idea that the fluid and simifluid as well as the solid constituents of the body contain the vital principle diffused through them he formed in 1755-6, when, in making drawings illustrative of the changes that the take place in the incubated egg, he noted specially that neither the white nor the yolk undergoes putrefaction. The blood he, with Harvey, considered to possess a vitality of its own, more or less independent of that of the animal in which it circulates. Life, he held, is preserved by the compound of the living body and the sourse of its solid constituents, the living blood. It is to the susceptibility of the latter to be converted into living organized tissue that the union of severed structures by the first intention is due. He even inclined to the belief that the chyle has life, and he considered that food becomes "animalized" in digestion. Coagulation of the blood he compared to the contraction of muscles, and believed to be an operation of life distinct from chemical coagulation, adducing in support of his opinion the fact that, in animals killed by lightning, by violent blows on the stomach, or by the exhaustion of hunting, it does not take place. "Breathing," said Hunter, "seems to render life to the blood, and the blood continues it in every part of the body."1 Life, he held, could be regarded as a fire, or something similar, and might for distinctions sake be called "animal fire." Of this the process of respiration might afford a constant supply, the fixed life supplied to the body in the food being set free and rendered active in the lungs, whilst the air carried off that possible which enclose and retains the existence of animal or vegetable matter itself, and may long exist without sensation. The principle upon which depends the power of sensation regulates all our external actions, as the principles of life our internal, and the two act mutually on each other in consequence of changes produced in the brain. Something (the "material vitae diffusa") similar to the components of the brain (the "material vitae coacervata") may be supposed to be diffused through the body and even contained in the blood ; between these a communication is kept up the nerves (the "chordae internunciae").3 Neither a material nor a chemical theory of life, however, formed a part of Hunters creed. "Mere composition of matter," he remarked, "does not give life ; for the dead body has all the composition it ever had ; life is a property we do not understand ; we can only see the necessary leading steps towards it." As from life only, said he in one of his lectures, we can gain an idea of death, so from death, so from death only we gain in idea of life. Life, being an agency leading to, but not consisting of, any modification of matter, "either is something superadded to matter, or else consists in a peculiar arrangement of certain fine particles of matter, which being thus disposed acquire the properties of life." As a bar of iron may gain magnetic virtue by being placed for a time in a special position, so perhaps the particles of matter arranged and long continued in a certain posture eventually gain the power of life. "I enquired of Mr Hunter," writes one of his pupils,5 "if did not make for the Exploded Doctrine of Equivocal Generation ; he told me perhaps it did, and that as to Equivocal Generation all we cd have was negative Proofs of its not taking Place. He did not deny that Equivocal Generation happened ; there were neither positive proofs for nor against its taking place."
To exemplify the differences between organic and inorganic growth, Hunter made and employed in his lectures a collection of crystallized specimens of minerals, or, as he termed them, "natural or native fossils." Of designated by him "extraneous fossils," because extraneous respecting the rocks in which they occur, he recognized the true nature, and he arranged them according to a system agreeing with that adopted for recent organisms. The study of fossils enabled him to apply his knowledge of the relations of the phenomena of life to conditions, as exhibited in times present, to the education of history of the earth in geological epochs. He observed the non-occurrence of fossils in granite, but with his customary scientific caution and insight could perceived no reason for supposing it to be the original matter of the globe, prior to vegetable or animal, or that its formation was different from that of other rocks. In water he recognized the chief agent in producing terrestrial changes (cf. Treatise on the Blood, p. 15 note) ;but the popular notion that the Noachian deluge might account for the marine organisms discovered on land he pointed out was untenable. From the diversity of the situations in which many fossils and allied living structures are found, he was led to infer that at various periods not only repeated oscillations of the level of the land, lasting thousands of centuries, but also great climatic variations, perhaps due to a change in the ecliptic, had taken place in geological times. Hunter considered that very few fossils of those that resembled recent forms are identical with them. He conceived that the latter might be varieties, but that if they are really different species, then "we must suppose that a new creation must have taken place." It would appear, therefore, that the origin of species in variation had not struck him as possible. That he believed varieties to have resulted from the influenced of changes in the conditions of life in times past is shown by a somewhat obscure passage in his "Introduction to Natural History" (Essays and Observations, i. 4), in which he remarks, "But, I think, we have reason to suppose that there was a period of time in which every species of natural production was the same, there being then no variety in any species," and adds that "civilization has made varieties in many species, which are the domesticated." Modern discoveries and doctrines as to the succession of life in time are again foreshadowed by him in the observation in his introduction to the description of drawings relative to incubation (quoted in Pref. to Cat. of Phys. Ser., i. p. iv., 1833) that :
"If we were capable of following the progress of increase of the number of the parts of the most animal, as they first formed in succession, from the very first, to its sated of full perfection, we should probably be able to compare it with some one of the incomplete animals themselves, of every order of animals in the creation, being at no stage different from some of those inferior orders; or, in other words, if we were to take a series of animals from the more imperfect to the perfect, we should probably find an imperfect animal corresponding with some stage of the most perfect."
In pathological phenomena Hunter discerned the results of the perturbation of those laws of life by which the healthy organism subsists. With him pathology was a science of vital dynamics. He afforded principles bearing not on single complaints only, but on the effects of injury and disease in general. To attempt to set forth what in Hunters teaching was now to pathology and systematic surgery, or was rendered so by his mode of treatment, would be well-nigh to present an epitome of all that he wrote on those subjects. "When we make a discovery in pathology," says Adams, writing in 1818, "we only learn what we have overlooked in his writings or forgotten in his lectures." Surgery, which only in 1745 had formally ceased to be associated with "the art and mystery of barbers, "he raised to the rank of a scientific profession. His doctrines were, necessarily, not those of his age : while lesser minds around him were still dim with the mists of the ignorance and dogmatism of times past, his lofty intellect was illumined by the dawn of a distant day.
