... scientific training as conducted in courses such as you are entering on. Up to a certain point I believe in set Lectures as excellent adjuncts to what is far more important, practical instruction at the bedside, in the operating room, and under the eye of the Demonstrator. But I am so far from wishing these courses extended, that I think some of them—suppose I say my own—would almost bear curtailing.

... shilling from the beginning.] The Professors, being busy and important men, lecture from their particular standpoints, and having lectured, bolt; there is no provision whatever for the intelligent discussion of knotty points, and the only way to get it is to buttonhole a demonstrator and induce him to neglect his task of supervising prescribed "practical" work in favour of educational talk. Let us, therefore, in view of this state of affairs, deal with the general question how a branch of thought and knowledge may be most beneficially studied ...
