These were selected as most likely to contain 

 the more important literature of biological- 

 chemical interest. They do not contain all, 

 by any means, as it is met with in the most 



unexpected places. It would be of interest to 

 compile a complete list of all the work of bio- 

 logical chemistry published by the various 

 American laboratories in all the periodicals, 

 American and foreign. This the writer must 

 leave to some one else. 



Table III. contains a list of the total num- 

 ber of articles and the number of those of bio- 

 logical-chemical nature, and in some cases, the 

 number of pages. As Sparks and Noyes 

 pointed out, and as many others have remarked 

 in discussing the subject, the number of pages 

 has no real significance in many instances. 

 Many short articles are of more value, scien- 

 tifically, than other articles with their hun- 

 dreds of pages. The length of an article de- 

 pends too much upon the nature of the sub- 

 ject and the personality of the writer, and not 

 enough upon its scientific value. 



Table IV. contains a comparison of the 

 number of articles (and pages in some in- 

 stances) in those periodicals published during 

 the periods 1907-1908 and 1915-191G. In those 

 cases where the periodical was not published in 

 1907, the figures for the later period are given 

 for comparison. 



These tables bring out, rather forcibly, first, 

 the large amount of biological work which is 

 being carried out in this country, and second, 

 the marked increase in this kind of research 

 during the past decade. The curve will drop
