Tlie very wide nutritive ratio of Experiment 6 caused 

 only a very small gain, because the absolute amount of 

 protein was very small, but that any gain at all was made 

 is doubtless due to the decrease of the protein consump- 

 tion by the large amount of carbhydrates. 



The other experiments show in general that a larger 

 proportion of the protein of the food is applied to the pro- 

 duction of flesh when the food has a medium nutritive 

 ratio than when it has a very narrow one. In detail, ex- 

 ceptions are to be expected, since, as above stated, the 

 experiments were not all made at the same time and the 

 bodily condition has much to do with the effect of a ration. 



Stohmann's experiments on goats, already described 

 (p. 146), also illustrate the advantage of a medium nutri- 

 tive ratio, as the following table shows :
