somewliat during tlie period of tlie duration of 

 the war, because of the large numbers of bio- 

 logical chemists and physicians who have al- 

 ready entered, and who will enter the govern- 

 ment service. However, we may look for a re- 

 turn to the highest point of the curve as soon 

 as normal conditions exist again. It would 

 seem that one of the lessons we must learn 

 from this terrible conflict is the national value 

 of scientific research.

Table V. contains a list of those institutions 

 which have published ten or more papers (bio- 

 logical) in any one of the four periodicals 

 tabulated, with the number of papers pub- 

 lished in the others. (Lack of time prevented 

 a complete classification of all the periodicals). 

 Table VI. classifies the articles in these four 

 periodicals according to the scheme used in 

 Chemical Ahstracts.

logical material which is being published 

 yearly. As Professor Vaughan remarks about 

 medical literature, some is good, some is bad, 

 and much of it is indifferent.'' While the di- 

 rect responsibility for the quality of the work 

 published depends upon the investigator him.- 

 self, some of this resiwnsibility must be laid 

 upon the teachers of biochemistry of this 

 country. This responsibility may even be car- 

 ried back still farther, as Dr. Hammett° has 

 recently pointed out, and may in part be 

 placed on the shoulders of the teachers of the 

 fundamentals of chemistry. It is a hopeful 

 sign, in view of this responsibility, to see so 

 large a number of the leaders of biological 

 chemistry gathered in this conference for the 

 improvement of its teaching. May the inspira- 

 tion which is gathered here send us back to our 

 desks and our laboratories with the determi- 

 nation to do our best the coming year to build 

 deep and strong the foundations upon which 

 the future biological publications will be based.
