"He is a little queer in his ideas -- an enthusiast in some branches of science. … I believe he is well up in anatomy, and he is a first-class chemist; but, as far as I know, he has never taken out any systematic medical classes. His studies are very desultory and eccentric, but he has amassed a lot of out-of-the way knowledge which would astonish his professors. … He is sure to be at the laboratory … He either avoids the place for weeks, or else he works there from morning to night. … Holmes is a little too scientific for my tastes -- it approaches to cold-bloodedness. I could imagine his giving a friend a little pinch of the latest vegetable alkaloid, not out of malevolence, you understand, but simply out of a spirit of inquiry in order to have an accurate idea of the effects. To do him justice, I think that he would take it himself with the same readiness. He appears to have a passion for definite and exact knowledge."
