328 nothing to memory, and made me draw up a short abstract of each lecture, which he read on the follow- ing evening, as a recapitulation to connect the sub- jects in the minds of the students." Amidst all his avocations, both as a lecturer and practitioner, Dr. John Hunter still pursued with an unabated zeal and industry his researches into com- parative anatomy. No opportunity for extending his knowledge on this interesting department of science did he permit to escape him. In the year 1773, at the request of Mr. Walsh, he dissected the torpedo, and laid before the Royal Society an ac- count of its electrical organs. A young elephant which had been presented to the queen by Sir Robert Barker, and had died, afforded him an oppor- tunity of examining the structure of that animal; after which two other elephants in the queen's menagerie likewise died, which he also carefully dissected. The year following, 1774, he published in the Philo- sophical Transactions an account of certain recep- tacles of air in birds, showing how these communicate with the lungs and are lodged in the fleshy parts and in the bones of these animals; likewise a paper on the gillaroo-trout, commonly called in Ireland the gizzard-trout. In 1775 several animals of the species called the Gymnotus electricus of Surinam were brought alive into this country, and by the curious phenomena they exhibited the attention of the scien- tific world was greatly excited. After making nu- merous experiments on the living animals, Mr. Walsh purchased those which died, and gave his friend Mr. Hunter an opportunity of examining them. This he readily accepted, and drew up an account of their electrical organs, which he published in the Philosophical Transactions. In the same volume of that valuable work will be found his paper contain- ing experiments respecting the powers of animals and vegetables in producing heat. Thus, in the paths of natural history did he find a recreation from the more serious, and often irksome duties of his profes- sion; and by his skilful dissections, and acute ob- servations, enriched our knowledge in this interest- ing and fascinating department of science. While thus engaged, Mr. Hunter found a great diffi- culty in showing to advantage the natural appearances of many parts of animals which he wished to be pre- served. In some instances the minute vessels could not be seen when the preparation was immersed in spirits, in others the natural colour of the parts pre- served; and even the character of the surface, faded and underwent a change after being some time im- mersed in this liquid—a circumstance which, to this day, diminishes very much the value of almost all the morbid preparations which are preserved in private and public museums. The only method therefore of accomplishing the object he had in view, was to have them carefully and correctly drawn at the time of the dissection. The expense of engaging draughts- men, the difficulty of procuring them, and above all their ignorance of the subject to be delineated, were considerable objections to their employment. Ac- cordingly he engaged a young and talented artist named Bell, to live with him for ten years, during which period it was agreed that he should be em- ployed both as a draughtsman and in making ana- tomical preparations. This young man soon im- bibed the spirit of his master; he worked assiduously with his knife, his forceps, and his pencil; he en- gaged himself during part of his time in copying out Mr. Hunter's lectures, and in less than ten years be- came a skilful anatomist and surgeon. By his labours Mr. Hunter's collection became enriched with many very accurate and spirited drawings, and a variety of curious and delicate anatomical preparations. This skilful artist, by the interest of his friend Sir Joseph Bankes, obtained the appointment of assistant-sur- geon in the Honourable East India Company for the settlement of Bencoolen in Sumatra, whither he set out with the view both of improving his fortune and collecting specimens of natural history. He was in both successful beyond his most sanguine expecta- tions. He sent home some very rare specimens of animals and corals, and two papers which appeared in the Philosophical Transactions—one giving a de- scription of the double-horned rhinoceros, and the other of an uncommonly formed fish. Unfortunately for the cause of science, he died of fever in 1792, being one of the many who have been summoned from this world amidst early promises of future ex- cellence and success. In January, 1776, Mr. Hunter was appointed sur- geon-extraordinary to his majesty—an honour which contributed still farther to advance his professional interests. About this time the attention of the public was much directed to the efforts of the Humane Society. Dr. Cogan was the first who introduced the subject from Holland; and after him Dr. Hawes did not suffer it to rest until it experienced the royal patronage. Here again we find Mr. Hunter zeal- ously engaged in endeavouring to ascertain the best mode of restoring apparently drowned persons, the consequence of which was the production of a paper which he read to the Royal Society, entitled Proposals for the Recovery of Persons Apparently Drowned. The able author of this paper draws the distinction between the mere suspension of the functions by which life is supported, and absolute death, which he illustrates by reference to various animals, in whom, under certain conditions, the actions of life are temporarily suspended. It further contains a description of the signs of life and death, which are of vast importance; indeed, notwithstanding the pro- gress that has since been made, both in Germany and Britain, in medical jurisprudence, this paper contains information which has by no means been superseded. In the autumn of this year Mr. Hunter was taken extremely ill, and the nature of his complaints in- duced both his friends and himself to apprehend that his life was in imminent danger. However, the an- ticipated calamity was averted; he rallied, and was restored to his friends and the public, to whom his subsequent services were of such vast importance. When on his sick-bed he reflected on his own worldly affairs, such as he was about to leave them;—he perceived that all his fortune had been expended in his pursuits; that his family had no provision except- ing what might arise from the sale of his collection; and he naturally, on this account, suffered much solicitude and anxiety. No sooner did he leave his sick chamber than he commenced arranging his col- lection, so that it might, in whatever event, com- mand its value, and with this view he began to make a catalogue of the collection; but the delicacy of his health obliged him to desist from his labours, and, persuaded by his friends and relatives, he retired for a time to Bath. During his absence Mr. Everard Home was employed to draw out descriptions of the preparations, leaving blanks for those with which he was unacquainted. His complaints were consider- ably ameliorated by his residence at Bath; and though he returned to town before he was quite convalescent, he continued to amend, and was soon recovered. In 1778 he published the second part of his Treatise on the Teeth, and also, in the Philosophical Transac- tions, a paper on the heat of animals and vegetables. In 1780 Mr. Hunter laid before the Royal Society an account of a woman who had the small-pox dur.
