THE CONTRIBUTION OF MEDICAL 



SCIENCE TO MEDICAL ART AS 



SHOWN IN THE STUDY OF 



TYPHOID FEVER i 



I interpret the gratifying invitation of 

 the Academic Senate to appear before you 

 as faculty research lecturer for the current 

 year not only as an opportunity of assem- 

 bling and correlating a group of facts that 

 I have been studying, but also as allowing 

 me to attempt an explanation of the method 

 by which such facts are obtained. I wish 

 in particular to suggest how one of the 

 more theoretic or so-called scientific 

 branches of medicine is utilized in the prac- 

 tical problem of preventing and curing 

 disease. 



There is little reason that many of you 

 should have attempted to differentiate be- 

 tween medicine as an art and medicine as 

 a science. Public interest and concern in 

 medicine deals with it largely as it is ap- 

 plied to the individual or community and 

 little with the scientific and more theoretic 

 investigations on which the progress of ap- 

 plied medicine depends. Medicine to the 

 layman is typified in the physician who at- 

 tends him and it is the noble and satisfac- 

 tory function of this individual to ease the 

 mind and body of his patient and fre- 

 quently so to apply his knowledge of human 

 structure and function in health and dis- 

 ease as to avert death and hasten recovery. 

 The practitioner employs the art of medi- 

 cine, that is to say he combines, modifies 

 and adopts certain recognized means to
