 gain in the last six days was fully eqtial to that at the be- 

 ginning. The table shows the results obtained during the 

 experiment proper (exclusive of the prelinunary feeding), 

 and also the protein consumption and the gain of protein 

 for the last five days of the feedhig with nitrogenous bye- 

 fodder.

The addition of protein to a ration poor in tliis sub- 

 stance caused a considerable gain of flesh by the animals. 

 At the same time, it did not fail to affect the protein con- 

 sumption, approximately doubling it in each case. We 

 conclude, then, that in the case of the herbivora protein 

 added to a ration does not pass so promptly and com- 

 pletely into circulatory protein as it does in the carnivora, 

 but maj cause a considerable gain of flesb. TMs inclina- 

 tion l^owai'd the formation of organized rather than circu- 

 latory pl^otein seems to be a characteristic of the herl)ivora, 

 perhaps due in part to the large amounts of non-nitrogen- 

 ous food which they consume and in piirt to the consider-
