EXPERIMENT STATION RECORD. 



The studies of the composition of meat and the dietary studies were 

 similar to those carried on previously under the auspices of the Depart- 

 ment of Agriculture at the University of Tennessee and other institu- 

 tions. The results of the dietary studies are briefly shown in the 

 following table:

The digestion experiments were made with healthy subjects. Two, 

 and sometimes three or four, subjects received the same kinds of food, 

 the quantities varying to suit the individuals. The food, mine, and 

 feces were analyzed according to the usual methods. The results of 

 the experiments are summarized in the following table:
