THE ESPECIAL VALVE OF BESEABCH IN 

 PUBE CHEMISTBYi 



Mt colleague, Dr. Cattell, having con- 

 sidered the broad topic of the value to a 

 democracy of research in pure science, I wel- 

 come the opportunity to take up for a few 

 moments one of the subdivisions of his field, 

 in order to point out somewhat more fully 

 the especial importance of research in 

 chemistry. 



Let us, therefore, first pass rapidly in 

 review a few of the contributions which 

 chemistry has made or is now making to 

 the health, happiness and material prosper- 

 ity of our country, that we may be able 

 more accurately to assess its value to the 

 community, gain a better appreciation of 

 the debt we owe it, and accord to it that 

 position of high honor and dignity which is 

 its just due. 



In the reports of the Twelfth Census of 

 the United States it is written that 



Probably no science has done so much as chem- 

 istry in revealing the hidden possibilities of the 

 wastes and by-products of manufacturers. This 

 science has been the most fruitful agent in the 

 conversion of the refuse of manufacturing opera- 

 tions into products of industrial value. Her fairy 

 wand has only to touch the most noisome sub- 

 stances, and the most ethereal essences, the most 

 heavenly hues, the most delicious flavors and odors 

 instantly rise as if by magic. 



Whether this is a wholly overdrawn pic- 

 ture or not will appear in what follows. 



Dealing with the ultimate constituents of 

 our material universe, their combinations 

 and transformations, it is chemistry that
