 the digestible nutrients. 



707. Henneberg's and Stohmann's investigations. It is to 

 the fundamental investigations of Henneberg and Stohmann 1 

 Sit the Weende Experiment Station, near Gottingen, that we 

 are indebted for the inauguration of a system of comparing the 

 values of feeding stuffs which has endured with little material 

 change up to the present time. These investigators were the 

 first to apply systematically in studying the nutrition of herbiv- 

 ora the physiological principles already demonstrated for other 

 classes of animals and to base their determinations upon the 

 outgo as well as upon the income of the body. Their earlier 

 experiments deal chiefly with the digestibility of feeding stuffs 

 and rations. Later a comprehensive scheme of investigation, 

 including determinations of the gaseous excreta, was laid out 2 

 and begun but never completed.
