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 scientific world was greatly excited. After making numerous 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 containing 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 profession; and by his skilful dissections, and acute observations, enriched our
knowledge in this interesting and fascinating department of science. While thus engaged, Mr Hunter found a great difficulty in showing to advantage the natural appearances of many parts of animals which he wished to be preserved.
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 preserved, and even the character of the surface, faded and underwent a change after being
some time immersed 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 draftsmen, the difficulty of procuring them, and above all their ignorance of the subject to be delineated, were considerable objections to their employment. Accordingly, 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 employed both as a draftsman and in making anatomical preparations. This young man soon imbibed the spirit of his master; he worked assiduously with his knife, his forceps, and his pencil; he engaged himself during part of his time in copying out Mr Hunter's lectures, and in less than ten years became 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 surgeon 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 expectations. He sent home some very rare specimens of animals and corals, and two papers which appeared in the Philosophical Transactions, one giving a description 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 excellence and success.
In January, 1776, Mr Hunter was appointed surgeon 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 zealously 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
