JOHN See also:HUNTER (1728-1793)  , See also:British physiologist and surgeon, was See also:born on the 13th 1 of See also:February 1728, at See also:Long See also:Calderwood, in the See also:parish of See also:East See also:Kilbride, See also:Lanarkshire, being the youngest of the ten See also:children of See also:John and See also:Agnes See also:Hunter . His See also:father, who died on the 3oth of See also:October 1741,2 aged 78, was descended from the old See also:Ayrshire See also:family of Hunter of Hunterston, and his See also:mother was the daughter of a Mr See also:Paul, treasurer of See also:Glasgow . Hunter is said to have made little progress at school, being averse to its restraints and pursuits, and fond of See also:country amusements . When seventeen years old he went to Glasgow, where for a See also:short See also:time he assisted his See also:brother-in-See also:law, Mr See also:Buchanan, a cabinetmaker . Being desirous at length of some settled occupation, he obtained from his brother See also:William (q.v.) permission to aid, under Mr See also:Symonds, in making dissections in his anatomical school, then the most celebrated in See also:London, intending, should he be unsuccessful there, to enter the See also:army . He arrived accordingly in the See also:metropolis in See also:September 1748, about a fortnight before the beginning of his brother's autumnal course of lectures . After succeeding beyond expectation with the See also:dissection of the muscles of an See also:arm, he was entrusted with a similar See also:part injected, and from the excellence of his second See also:essay Dr Hunter predicted that he would become a See also:good anatomist . Seemingly John Hunter had hitherto received no instruction in preparation for the See also:special course of See also:life upon which he had entered . Hard-working, and singularly patient and skilful in dissection, Hunter had by his second See also:winter in London acquired sufficient anatomical knowledge to be entrusted with the See also:charge of his brother's See also:practical class . In the summer months of 1749-1750, at See also:Chelsea Military See also:Hospital, he attended the lectures and operations of William See also:Cheselden, on whose retirement in the following See also:year he became a surgeon's See also:pupil at St See also:Bartholomew's, where Percivall See also:Pott was one of the See also:senior surgeons . In the summer of 1752 he visited See also:Scotland . See also:Sir Everard See also:Home and, following him, Drewry Ottley See also:state that Hunter began in 1754 to assist his brother as his partner in lecturing; according, however, to the See also:European See also:Magazine for 1782, the See also:office of lecturer was offered to Hunter by his brother in 1758, but declined by him on See also:account of the " insuperable embarrassments and objections " which he See also:felt to speaking in public .

In 1754 he became a surgeon's pupil at St See also:

George's . Hospital, where he was appointed See also:house-surgeon in 1756.3 During the See also:period of his connexion with Dr Hunter's 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 See also:nose, experimentally tested the question whether See also:veins could See also:act as absorbents, studied the formation of pus and the nature of the placental circulation, and with his brother earned the See also:chief merit of practically proving the See also:function and importance of the lymphatics in the See also:animal See also:economy . On the 5th of See also:June 1755,4 he ' The date is thus entered in the parish See also:register, see See also:Joseph See also:Adams, See also:Memoirs, Appendix, p . 203 . The Hunterian Oration, instituted in 1813 by Dr See also:Matthew See also:Baillie and Sir Everard Home, is delivered at the Royal See also:College of Surgeons on the 14th of February, which Hunter used to give as the anniversary of his See also:birth . " Ottley's date, 1738, is inaccurate, see S . F . See also:Simmons, Account of . . . IV . Hunter, p . 7 .

Hunter's mother died on the 3rd of See also:

November 1751, aged 66 . 3 So in Home's Life, p. xvi., and Ottley's, p . 15 . Hunter himself (See also:Treatise on the See also:Blood, p . 62) mentions the date 1755 . Ottley incorrectly gives 1753 as the date . In the See also:buttery See also:book for 1755 at St See also:Mary's See also:Hall his See also:admission is thus noted: " See also:Die Junii 5O° 1755 Admissus est Johannes Hunter superioris ordinis Commen-was induced to enter as a See also:gentleman commoner at St Mary's Hall, See also:Oxford, but his instincts would not permit him, to use his own expression, " to stuff Latin and See also:Greek at the university." Some three and See also:thirty years later he thus significantly wrote of an opponent: " See also:Jesse See also:Foot accuses me of not understanding the dead See also:languages; but I could See also:teach him that on the dead See also:body which he never knew in any See also:language dead or living."5 Doubtless, however, linguistic studies would have served to correct in him what was perhaps a natural defect—a difficulty in the presentation of abstract ideas not wholly attributable to the novelty of his doctrines . An attack of inflammation of the lungs in the See also:spring of 1759 having produced symptoms threatening See also:consumption, by which the promising medical career of his brother See also:James had been cut short, Hunter obtained in October 176o the See also:appointment of See also:staff-surgeon in See also:Hodgson and See also:Keppel's expedition to Belleisle . With this he sailed in 1761 . In the following year he served with the See also:English forces on the frontier of See also:Portugal . Whilst with the army he acquired the extensive knowledge of gunshot wounds embodied in his important treatise (1794) 011 that subject, in which, amongst other matters of moment, he insists on the rejection of the indiscriminate practice of dilating with the See also: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 the coagulation of the blood were among the subjects of his inquiries.6 Later, on See also:

land, he continued the study of human See also:anatomy, and arranged his notes and memoranda on inflammation; he also ascertained by experiment that digestion does not take See also:place in See also:snakes and lizards during See also:hibernation, and observed that enforced vigorous See also:movement at that See also:season proves fatal to such animals, the See also:waste so occasioned not being compensated, whence he See also:drew the inference that, in the diminution of the See also:power of a part attendant on See also:mortification, resort to stimulants which increase See also:action without giving real strength is inadvisable,' A MS. See also:catalogue by Hunter, probably written soon after his return from Portugal, shows that he had already made a collection of about two See also:hundred specimens of natural and morbid structures . On arriving in See also:England See also:early in 1763, Hunter, having retired from the army on See also:half-pay, took a house in See also:Golden Square, and began the career of a London surgeon . Most of the See also:metropolitan practice at the time was held by P . Pott, C . See also:Hawkins, See also:Samuel See also:Sharp, Joseph See also:Warner and See also:Robert See also:Adair; and Hunter sought to eke out his at first slender income by teaching practical anatomy and operative See also:surgery to a private class . His leisure was devoted to the study of See also:comparative anatomy, to procure subjects for which he obtained the refusal of animals dying in the See also:Tower See also:menagerie and in various travelling zoological collections . In connexion with his rupture of a tendo Achillis,8 in 1767, he performed on See also:dogs several experiments which, with the illustrations in his museum of the See also:reunion of such structures after See also:division, laid the See also:foundation of the See also:modern practice of cutting through tendons (tenotomy) for the See also:relief of distorted and contracted See also:joints . In the same year he was elected F.R.S . His first contribution to the Philosophical Transactions, with the salis." Hunter apparently See also:left Oxford after less than two months' See also:residence, as the last entry in the buttery book with charges for battels against his name is on See also:July 25, 1755 . His name was, how-ever, retained on the books of the Hall till See also:December to, Ii56 . The See also:record of Hunter's matriculation runs: " Ter° Trin . 1755.--Junii 5to Aul .

Ellis in the See also:volume for 1766, was an essay on See also:post-mortem digestion of the See also:stomach, written at the See also:request of Sir J . See also:Pringle, and read on the 18th of June 1772, in which he explained that phenomenon as a result of the action of the gastric juice.' On the 9th of December 1768 he was elected a surgeon to St George's Hospital, and, soon after, a member of the See also:Corporation of Surgeons . He now began to take house-pupils . Among these were See also:Edward See also:Jenner, who came to him in 1770, and until the time of Hunter's See also:death corresponded with him on the most intimate and affectionate terms, W . See also:Guy, Dr P . S . Physick of See also:Philadelphia, and Everard Home, his brother-in-law . William See also:Lynn and Sir A . See also:Carlisle, though not inmates of his house, were frequent visitors there . His pupils at St George's included John See also:Abernethy, See also:Henry Cline, James See also:Earle and See also:Astley See also:Cooper . In 1770 he settled in Jermyn See also:Street, in the house which his brother William had previously occupied; and in July 1771 he married See also:Anne, the eldest daughter of Robert Home, surgeon to See also:Burgoyne's See also:regiment of See also:light See also:horse .2 From 1772 till his death Hunter resided during autumn at a house built by him at See also:Earl's See also:Court, See also: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 partridges, at least one See also:eagle, toads, silkworms, and many more creatures, obtained from every See also:quarter of the globe .

Bees he had under observation in his conservatory for upwards of twenty years; hornets and wasps were also diligently studied by him . On two occasions his life was in See also:

risk from his pets—once in See also:wrestling with a See also:young See also:bull, and again when he fearlessly took back to their See also:dens two leopards which had broken loose among his dogs . Choosing intuitively the only true method of philosophical See also:discovery, Hunter, ever cautious of confounding fact and See also:hypothesis, besought of nature the truth through the See also:medium of manifold experiments and observations . " He had never read See also:Bacon," says G . G . See also:Babington, " but his mode of studying nature was as strictly Baconian as if he had."3 To Jenner, who had offered a conjectural explanation of a phenomenon, he writes, on the 2nd of See also:August 1775: " I think your See also:solution is just; but why think? why not try the experiment ? Repeat all the experiments upon a See also:hedgehog' as soon as you receive this, and they will give you the solution." It was his See also:axiom however, " 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 that principle to useful purposes " (" Anim . Oecon.," Works, iv . 86) . During ' The subjects and See also:dates of his subsequent papers in the Trans-actions, the titles of which give little notion of the richness of their contents, are as follows: The See also:torpedo (1773); See also:air-receptacles in birds, and the Gillaroo See also:trout (1i74); the Gymnotus electricus, and the See also:production of See also:heat by animals and vegetables (supplemented in 1777), (1i75); the recovery of See also:people apparently drowned (1776); the See also:free See also:martin (1779); the communication of smallpox to the foetus in utero, and the occurrence of male plumage in old See also:hen pheasants (178o); the See also:organ of See also:hearing in fishes (1782); the anatomy of a " new marine animal " described by Home (1785) ; the specific identity of the See also:wolf, See also:jackal and See also: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 See also: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 . 2 Mrs Hunter died on the 7th of See also:January 1821, in Holies Street, See also: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 See also:

Haydn's English canzonets were supplied by her, and were mostly See also:original poems; of these the lines beginning " My mother bids me bind my See also:hair " are, from the beauty of the accompanying See also:music, among the best known . (See R . See also:Nares in Gent . Mag. xci. pt . 1, p . 89, quoted in See also:Nichols's Lit . Anec., 2nd See also:ser., vii . 638.) Hunt . Orat., 1842, p . 15 . The See also:condition of this animal during hibernation was a subject of special See also:interest to Hunter, who thus introduces it, even in a See also:letter of condolence to Jenner in 1778 on a disappointment in love: " But let her go, never mind her .

I shall employ you with hedgehogs, for I do not know how far I may See also:

trust mine."fifteen years he kept a See also:flock of geese simply in See also:order to acquaint himself with the development of birds in eggs, with reference to which he remarked: " It would almost appear that this mode of See also: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 See also:brute creation and in See also:man, he had already, in 1780, as he states, " poisoned some thousands of animals." 5 By inserting shot at definite distances in the See also:leg-bones of young pigs, and also by feeding them with See also:madder, by which all fresh osseous deposits are tinged,s Hunter obtained See also:evidence that bones increase in See also:size, not by the intercalation of new amongst old particles, as had been imagined by H.L . See also:Duhamel du Monceau, but by means of additions to their extremities and circumference, excess of calcareous See also:tissue being removed by the absorbents . Some of his most extraordinary experiments were to illustrate the relation of the strength of constitution to See also:sex . He exchanged the spurs of a young See also:cock and a young pullet, and found that on the former the transplanted structure See also:grew to a See also:fair size, on the latter but little; whereas a See also:spur from one leg of a cock transferred to its See also: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.' 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 See also:possession of " the See also:simple living principle." 5 The effects of See also:habit upon structure were illustrated by Hunter's observation that in a See also:sea-See also:gull which he had brought to feed on See also:barley the See also:muscular parietes of the gizzard became greatly thickened .. A similar phenomenon was noticed by him in the See also:case of other carnivorous birds fed on a See also:vegetable See also:diet . It was in 1772 that Hunter, in order effectually to See also:gauge the extent of his own knowledge, and also correctly to See also:express his views, which had been repeatedly misstated or ascribed to others, began his lectures on the theory and practice of surgery, at first delivered free to his pupils and a few See also:friends, but subsequent to 1774 on the usual terms, four guineas . Though Pott, indeed, had perceived that the only true See also:system of surgery is that which most closely accords with the curative efforts of nature, a rational See also: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 See also:mystery, and whose books contained little else than relations of cases and modes of treatment, sought the See also:reason for each phenomenon that came under his See also: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 See also:Chinese philosopher whose knowledge consisted only in facts." Too much See also:attention, he remarked, cannot be paid to facts; yet a multitude of facts overcrowd the memory without See also:advantage if they do not See also:lead us to establish principles, by an acquaintance with which we learn the causes of diseases . Hunter's course, which latterly comprised eighty-six lectures, delivered on alternate evenings between the See also:hours of seven and eight, lasted from October to See also:April . Some teachers of his time were content to dismiss the subjects of anatomy and surgery in a course of only six See also:weeks' duration .

His class was usually small and never exceeded thirty . He was deficient in the gifts of a good extempore See also:

speaker, being in this respect a remarkable contrast to his brother William; and he read his lectures, seldom raising his eyes from the See also:manuscript . His manner with his 5 See his evidence at the trial of See also:Captain Donellan, Works, i . 195 . 6 On the discovery of the See also:dyeing of bones by madder, see Belchier, Phil . Trans., vol. xxxix., 1736, pp . 287 and 299 . Essays and Observations, i . 55, 56 . " May we not claim for him," says Sir Wm . See also:Fergusson, with reference to these experiments, " that he anticipated by a hundred years the scientific data on which the See also:present system of human grafting is conducted ? " (Hunt .

Orat., 1871, p . 17) . 6 Essays and Observations, i . 115; cf . Works, i . 391 . auditory is stated to have been embarrassed and awkward, or, as Adams puts it (Obs. on Morbid 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 likely I shall think differently next year "; and once in See also:

answer to a question 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." In January 1776 Hunter was appointed surgeon-extraordinary to the See also:king . He began in the same year his Croonian lectures on muscular See also:motion, continued annually, except in 1777, till 1782: they were never published by him, being in his See also:opinion too incomplete . In 1778 appeared the second part of his Treatise on the Natural See also:History of the Human See also: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 1754–1755, as he tells us. he received his first hint of the use of the absorbents. ahernethy (Physiological Lectures, p . 196) relates that Hunter, icing once asked how he could suppose it possible for absorbents o do such things as he attributed to them, replied, " See also:

Nay, I know not, unless they possess See also:powers similar to those which a See also:caterpillar exerts when feeding on a See also:leaf." Hunter in 178o 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 (irculation . His brother William, who had five years previously described the same in his Anatomy of the Gravid Uterus, there-upon wrote to the Society attributing to himself this See also:honour . John Hunter in a rejoinder to his brother's letter, dated the 17th of February 1780, reiterated his former statement, viz. that his discovery, on the evening of the See also:day in 1754 that he had made it in a specimen injected by a Dr See also:Mackenzie, had been communicated by him to Dr Hunter . Thus arose an estrangement between the two Hunters, which continued until the time of William's last illness, when his brother obtained permission to visit him . In 1783 Hunter was elected a member of the Royal Society of See also:Medicine and of the Royal See also:Academy of Surgery at See also:
