Abernethy was elected assistant surgeon of St. Bartholomew's Hospital, July 15th, 1787. Sir Charles Blicke, an assistant surgeon, had been appointed to the surgeoncy vacant by the resignation of Mr. Pott, and Abernethy succeeded to the assistant surgeoncy thus vacated. The election was contested by two or three other candidates; amongst the rest, by Mr. Heaviside. This gentleman was an eminent surgeon, and a gentlemanly, facetious, and agreeable companion. He was originally in the Guards, and practised in London many years with great credit and respectability. He was fond of science, and expended considerable sums in the formation of an interesting museum. In the earlier part of his life, he gave conversaziones, which were attended by great numbers both of the scientific and fashionable. He lived in a day when, if a gentleman felt himself insulted, he had at least the satisfaction of being relieved from his sensibility by having his brains blown out in a duel—professionally speaking, by a kind of "operative surgery;" viz. the demolition of the organ in which the troublesome faculty resided. Mr. Heaviside, in his professional capacity, is said to have attended more duels than any other surgeon of his time. This gentleman, albeit not unused to one kind of contest, retired from that at the hospital; which then lay between Mr. Jones and Mr. Abernethy—the former polling twenty-nine, the latter fifty-three votes. This was an important epoch in the life of Abernethy. It is difficult to adjust the influence which it ultimately exerted, for good or evil, on his future prospects and happiness, or on his relations to science. The hospital had thus secured a man of extraordinary talent, it is true, and in spite of a system which indefinitely narrows the field of choice; but then the same "system" (which we shall by and by describe) kept Abernethy, as regards the hospital, for no less a term than twenty-eight years, in a position which, although it did not exclude him altogether from the field of observation it afforded, did much to restrict his cultivation of it. His talents for observation, nevertheless, and the estimation in which he was soon held, no doubt enabled him, to a certain extent, to bring many of his views to the test of practice. Still, as an assistant surgeon, except in the absence of his chief, he had officially nothing to do; whatever cases he conducted, were only by sufferance of his senior.
