The Rapidity \^tli ^?«r]iieh Equilit)rinin is estals- 

 lished varies. — It is greater the richer the food is in al- 

 buminoids and the lebS fat ib contained in the body ; in 

 general, therefore, in the earnivora than in the herbi\ ora. 



The influence of the fat of the btKly in decreasing the 

 protein consumption is of great importance. It has been 

 proved beyond a doubt that in a fat body, the mabS of 

 flesh, the food, etc., being the same, the protein consump- 

 tion is less than in a lean body. It is not, ho\ie\er, sim- 

 ply the absolute quantity of fat, but rather its amount 

 relatively to that of the flesh which is the important point 



But not only is the protein consumption less in a fat 

 body, cMm^k parHyuSj but the rapidity with which equih- 

 brium is reached after a change in the food is less. 



The following are the results of two experiments, A on 

 a lean animal (dog), B on a fat one :

A smaller increase of protein in the food of the fat ani- 

 mal caused both a relatively and absolutely greater gain of 

 flesh, which ako continued twice as long. Numerous other 

 examples of the same eftect might be adduced, were it ne- 

 cessary. 



As a consequence of this fact, a gain of flesh can be 

 made more readily by herbivora than by earnivora, since
