tlie carbhydrates exert tlie same influence on the protein 

 eonsnmption as does fat, viz. : render it less than it other- 

 wibe would be. 



In almost every case the effect of the addition of carb- 

 hydrates was not only to decrease the protein consumption 

 but to render it less than" the supply, and thus to cause a 

 £>:ain of flesh instead of the loss wiiich had been taking: 

 place. 



The action of the earbhydrates in decreasing the protein 

 consumption is also to be seen in experiments on herbivora, 

 though in these it is seldom so shai-ply expressed as 

 in the results just given, because these animals, in any 

 case, receive large amounts of earbhydrates and the 

 effect of a further addition is therefore comparatively 



""gLw. «peH„„^ ^ow pUi.,, ^. ,^^ of 



the protein consumption caused by the addition of sugar, 

 even to straw fodder, which of itself contains much earb- 

 hydrates and little protein. 



Some of Ilenneberg & Stohmann's experiments in 1865 

 also show this action of the earbhydrates. The quantities 

 are per day and head.
