[3] The following, extracted from the MS. notes of a student, may be taken as a specimen of Knox's mode of dealing with his brethren:-"Before commencing to-day's lecture, I am compelled by the sacred calls of duty to notice an extraordinary surgical operation which has this morning been performed in a neighbouring building by a gentleman [Mr Liston] who, I believe, regards himself as the first surgeon in Europe. A country labourer from the neighbourhood of Tranent came to the Infirmary a few days ago with an aneurism of considerable extent, connected with one of the large arteries of the neck; and, notwithstanding of its being obvious to the merest tyro that it was an aneurism, the most distinguished surgeon in Europe, after an apparently searching examination, pronounced it to be an abscess. Accordingly, this professional celebrity--who, among other things, plumes himself upon the wonderful strength of his hands and arms, without pretension to head, and is an amateur member of the ring--plunged his knife into what he thus foolishly imagined to be an abscess; and the blood, bursting forth from the deep gash in the aneurismal sac, the patient was dead in a few seconds. This notable member of the profession is actually an extra-academical lecturer on surgery in this great metropolis; and on this occasion was assisted by a gentleman similarly constituted, both intellectually and physically, who had been trained up under the fostering care of a learned professor in a certain university, who inherited his anatomical genius from his ancestors, and who has recently published a work on the anatomy of the human body, in which, among other notabilities, no notice is taken of the pericardium. Tracing the assistant of our distinguished operator further back, I have discovered that he had been originally apprenticed to a butcher of this city, but that he had been dismissed from this service for stealing a sheep's head and trotters from his employer's shambles. It is surely unnecessary for me to add that a knowledge of anatomy, physiology, pathology, and surgery, is neither connected with nor dependent upon brute force, ignorance, and presumption; nor has it anything to do with an utter destitution of honour and common honesty."--(Roars of applause, mixed with a few hisses.)
