248 ADDRESS ON UNIVERSITY EDUCATION ix 



few hours devoted to the examination of specimens 

 of such plants, and the desirableness of such 

 knowledge is no justification, to my mind, for 

 spending three months over the study of systematic 

 botany. Again, materia medica, so far as it is a 

 knowledge of drugs, is the business of the druggist. 

 In all other callings the necessity of the division of 

 labour is fully recognised, and it is absurd to require

 more relevancy, than the knowledge of how the 

 steel of his scalpel is made. 



All knowledge is good. It is impossible to say 

 that any fragment of knowledge, however insigni- 

 ficant or remote from one's ordinary pursuits, may 

 not some day be turned to account. But in medical 

 education, above all things, it is to be recollected 

 that, in order to know a little well, one must be

Let it not be supposed that I am proposing to 

 narrow medical education, or, as the cry is, to lower 

 the standard of the profession. Depend upon it 

 there is only one way of really ennobling any call-
