We also find him engaged in inquiries involving much more extended views than were in that day _generally_ associated with the study of _surgery_. He very early participated in those researches which had for their object to determine the relation of the digestive functions to one of the most recondite affections of an extremely important organ (the kidney). "When I was a boy," said he, "I half ruined myself in buying oranges and other things, to ascertain the effects of different kinds of diet in this disease." The same researches show how early also he began to perceive the importance of chemistry in investigating the functions of different organs, and in _aiding_, generally, physiological researches. We have heard a contemporary and a lecturer on chemistry attest Abernethy's proficiency in that science. As his investigations proceeded, he had the still higher merit of taking _just and sober views_ of the relations of chemistry to physiological science. We mean that whilst he fully recognized the importance of it, he entirely avoided that _exclusive_ reliance on it which is too often created by some of the more striking demonstrations of chemical science; that one—idea—tendency, which unconsciously wrests it to the solution of phenomena which, in the _present state_ of our knowledge, it is wholly inadequate to explain. We have alluded to the foregoing facts touching the impressions derived from his apprenticeship, and his early disposition for philosophical research, because both will be found to have relations to his subsequent labours and peculiarities. Diligent as he was, we suspect he found, during his apprenticeship, little of those attractions which make labour and industry sources of happiness and pleasure. As a matter of course, he would have been allowed to attend any lectures which were given at the hospital to which Sir Charles Blicke was surgeon (St. Bartholomew's), and this would bring him in contact with Mr. Pott, who delivered a certain number of surgical lectures there. There were no _courses_ of anatomical lectures given at St. Bartholomew's at that period; but anatomical lectures were delivered regularly at the London Hospital, by Dr. Maclaurin and Sir William Blizard, and afterwards by Sir William Blizard alone. As Sir Charles Blicke lived in Mildred's Court and subsequently in Billiter Square, Abernethy would be about equidistant from the two hospitals, both of which he attended. We incline to think that it was in attending these lectures, and perhaps especially those of Sir William Blizard, that he first found those awakening impulses which excited in him a real love for his profession.
