those who have been interested in the nutri- 

 tion investigations under the department, for 

 it is a direct outgrowth of the letter's work 

 which has led up to it and made it possible. 

 The development of the respiration calorimeter 

 under the department's cooperation, and the 

 fundamental inquiries which have been con- 

 ducted with it for several years past, have 

 stimulated research in this field; and as the 

 apparatus has remained the only one of its 

 kind in the country it has been looked to as 

 the means of putting to exact test the deduc- 

 tions and conclusions from other investiga- 

 tion. 



The wide interest awakened in nutrition 

 studies, and the experimental methods which 

 have been elaborated, are substantial products 

 of the department's work and influence in this 

 line, and the step taken by one of the highest 

 research institutions of the country is an indi- 

 cation of the way in which the department's 

 work may prepare the way for and stimulate 

 research in the broader fields of science. 



While plans for the continuation of these 

 studies are not fully matured, it is expected 

 that the respiration calorimeter at Middle- 

 town will be moved to "Washington and in- 

 stalled in the new laboratories now building 

 on the department grounds. — Experiment
