SOME PRESENT ASPECTS OF CHEM- 

 ISTRY IN THE UNITED STATES ^ 



It has often been observed that those living 

 in the midst of great events sometimes fail 

 to understand the far-reaching effects of the 

 occurrences going on around them. During 

 revolutionary times attention is so riveted 

 upon the single occurrences which follow each 

 other with bewildering rapidity that the par- 

 ticipants often fail to view the succession of 

 events as a whole and thus miss their full sig- 

 nificance. Eevolution is scarcely too strong 

 a word to apply to the changes relating to 

 chemistry which are taking place in this coun- 

 try. The very great impetus which the science 

 of chemistry has experienced during recent 

 years brings with it a series of problems vitally 

 related to the science as a whole, to our educa- 

 tional institutions and to industry. 



It seems appropriate that on this occasion 

 we might with profit, to borrow a business ex- 

 pression, take stock of the present situation. I 

 shall therefore endeavor to give a brief and 

 partial analysis of the outstanding features of 

 the existing conditions, which are more or less 

 confused, and lay down a few broad principles 

 which appear to ofler a sound basis of future 

 development. 



The events of the past five years have ex- 

 erted a profound influence not only upon 

 chemistry but upon various other sciences rep- 

 resented by the American Association for the 

 Advancement of Science. To meet the critical 

 situation presented in 1914 and the more criti- 

 cal condition in 1917, the country called to its 

 service the entire scientific resources at its 

 co m mand and nearly every branch of science 

 contributed something, either directly or in- 

 directly, to aid in the solution of the pressing 

 problems preseL.'fid. The geologist was called
