SKETCH OF RUSSELL H. CHITTENDEN. 121 



patliogenic bacteria, with tlie impetus this fact has given to the 

 search for methods of producing immunity. Then, too, we must not 

 forget to recall the great aid chemistry has lent to therapeutics, not 

 only giving us methods for the preparation of purer and more definite 

 products, but opening up methods of studying the physiological 

 action of drugs which have greatly advanced the growth of scientific 

 pharmacology." 



A course in physiological chemistry worthy of the name should 

 extend. Professor Chittenden thought, at least through half the col- 

 lege year, and preferably through a whole year, with an average of 

 fifteen hours of laboratory work a week, interspersed with lectures, 

 recitations, and demonstrations. It could be advantageously under- 

 taken only by men who already have knowledge of general, analyt- 

 ical, and organic chemistry, physics, anatomy, and histology, together 

 with more or less familiarity with general physiology. An outline of 

 the order of such a course as existed in the author's mind is given in 

 the address, with the observation that, to make it of the highest value, 

 no opportunity should be lost to show the physiological bearing of 

 all the results obtained; to try and instill into the mind of the stu- 

 dent the idea that the facts of physiological chemistry have a wide 

 application. 



The biological course (purely optional), started originally in the 

 Scientific School, is now open also to those junior and senior students 

 in the academical department who are desirous of taking this line of 

 work. Naturally, the majority of the students electing this course of 

 study, extending through two years of the college course, are intend- 

 ing to enter upon the study of medicine after graduation, and it is 

 interesting to note that the graduates of this course almost invariably 

 take a high standing in their professional study, thereby indicating 

 the beneficial effects of their biological training. 



To-day the Sheffield laboratory of physiological chemistry is 

 a very different structure from the laboratory of twenty-three years 

 ago. Situated in what was formerly the Sheffield mansion, on Hill- 

 house Avenue, nine good-sized rooms are required to care for the 

 many students working there, while one assistant professor and three 

 instructors aid in carrying on the instruction given. 



In addition to his duties at Yale, Professor Chittenden has re- 

 cently been made lecturer on physiological chemistry at Columbia 

 University. 



The list of Professor Chittenden's publications to date contains 

 ninety-three titles of papers, etc., nearly all contributions to scientific 

 journals and the proceedings of scientific societies, and nearly all 

 bearing on physiological chemistry or subjects related to it.
