logical, chemical, and i)liYsical science combined. Physiology ad- 

 vances by making applications of the principles, the methods, and the 

 implements of all three sciences. . . . The world has observed, and 

 will not forget, that some of the greatest contribntors to the progress 

 of medicine and surgery during the past thirty years have been not 

 physicians, but naturalists and chemists. Pasteur was a chemist ; 

 Cohn, the teacher of Koch, a botanist, and Metchnikoff a zoologist. 

 Students of disease must therefore be competent to utilize in their 

 great task every aid which natural science can furnish. How vastly 

 is the range of medical science and medical education broadened by 

 this plain necessity ! The dignity and serviceableness of the medical 

 profession are heightened by every new demand on the intelligence 

 and devotion of its members." 



This thought was also voiced by Doctor Welch, who declared the 

 subject-matter of medical study to be " complex and difficult far 

 beyond that of any other natural or physical science." He advocated 

 specialization as a great instrument of progress, for, although the va- 

 rious branches of medical science are interdependent, each has its own 

 problems and methods, and " each is most fruitfully cultivated for 

 its own sake by those specially trained for the work. . . . But the 

 further division of labor is carried the more necessary does it become to 

 emphasize essential unity of purpose and to secure coordination and 

 cordial cooperation of allied sciences." 



In the creative work of research and investigation the genius and 

 ability of the man were placed above all else. Important as are the 

 most ample and freely available facilities for productive research, 

 " men count for more than stately edifice and all the pride and pomj^ 

 of outward life. Research is not to be bought in the market place, 

 nor does it follow the commercial law of supply and demand. The 

 multitude can acquire knowledge; many there are who can impart it 

 skillfully ; smaller, but still considerable, is the number of those who 

 can add new facts to the store of knowledge, but rare indeed are the 

 thinkers, born with the genius for discovery and with the gift of the 

 scientific imagination, to interpret in broad generalizations and laws 

 the phenomena of nature. These last are the glory of a university. 

 Search for them far and wide beyond college gate and city wall, and 

 when found cherish them as a possession beyond all price." 



The analogy l^etween medicine and agriculture is not far to seek. 

 This is especially the case when they are considered from the stand- 

 point of their scientific development and their broad relationships. 

 They have many points of similarity, and hence the lesson of the one 

 may be applicable to the other. 



The scientific aspects of both agriculture and medicine present 

 very complex problems, those of the former quite as much as Doctor
