this division have been considered in this 

 study.2 



The first indication of the increased in- 

 terest in biological research may be foimd in 

 the large number of publications which have 

 been founded and successfully continued dur- 

 ing this period. The principal periodicals 

 published prior to 1907 are given in Table I. 

 The date indicates the year of the first pub- 

 lication.

3 It should be remarked in this connection that 

 chemistry is only one of the sciences which have 

 been used in the study of biological phenomena. 

 A similar study might be made for each of the 

 other sciences, especially physics. 



Journal of Immunology 1916 



Quarterly Cumulative Index to Current Med- 

 ical Literature 1916 



American Journal of Syphilis 1917 



Abstracts of Bacteriology 1917 



American Beview of Tuberculosis 1917 



Journal of Urology 1917 



The number of journals which have sprung 

 into existence since 1914 is very noticeable. 

 Many of these probably owe their existence, 

 in part at least, to the fact that publication 

 in German magazines was cut off by the war. 

 It is to be hoped that they may survive after 

 the war, when many scientific investigators 

 will again be tempted to publish in German. 



Special attention should be directed to the 

 two abstract journals. Chemical Ahstracts 

 is b.y far the most complete abstract journal 

 published in any language. It covers nearly 

 700 periodicals (671 titles are given in the 

 1915 list; many have been added since then, 

 as the 1917 list, shortly to appear, will show. 

 Still others are covered through other abstract 

 journals, about a dozen of which are regularly 

 checked). The Biological Ahstracts, so well 

 organized by Professor Gies, and carefully 

 edited by his staff, are especially complete. 

 Very few, if any articles of biological interest 

 are missing. The fact that about 10,000 

 copies are in circulation must add to the value 

 of American scientific research. Ahstracts of 

 Bacteriology covers a similar field for the 

 bacteriologist and appears to be equally well 

 organized. And finally, the Cumulative In- 

 dex of Current Medical Literature, issued 

 quarterly, gives in one index the current 

 medical and biological literature. We are 

 grateful for these publications, whether we 

 express it or not. They lighten very much 

 the burden of reference hunting. 



The following journals have been used in 

 the study recorded here: 



American Journal of the Diseases of Children 

 American Journal of Medical Sciences 

 American Journal of Physiology 

 Archives of Internal Medicine 

 Journal of Agricultural Research 

 Journal of the American Chemical Society 

 Journal of Bacteriology
