body, but seems rather to inof^ease it sliglitly. Tliis latter 

 effect lias been observed iii otlier experiments, and appears 

 to be due to the influence of the fat in drawing into cir- 

 culation the organized protein of the body. It shows it- 

 self still more markedly when, along with the fat, an 

 amount of albuminoids not sufl&cient to balance the con- 

 sumption is given. 



The effect is in every case small, and this action of fat 

 is far more than comiterbalanced by another wiiich shows 

 itself when it is fed along wdth a sufficient quantity of 

 protein. 



Carbhydrates alone do not decrease the Protein 

 C6nsumption any more than does fat. The same amount 

 of protein is oxidized and destroyed in the body as in the 

 complete absence of food. They differ from fat, however, 

 in the fact that they do not, like the former, slightly in- 

 crease the protein consumption. They are simply without 

 effect on it when fed exdusimly. 



§ 5. Feeding- with Pkotein aijtd Fat. 



The Protein Consuinption is deternained chiefly 

 by the Supply of it in the Food, just as it ib in feed- 

 ing exclusively with albuminoids, and any increase in the 

 amount of the latter causes a coiTesponding increase in 

 the former. Thus, Voit {Iog, cit) obtained the following
