deposition of flesli in tlie body of a dog, e. g,, as possible, 

 we should not feed large quantities of meat with fat. 

 The absolute quantity of albuminoids in the food does 

 not determine the gain, but only the protein consumption. 

 Neither is it the absolute quantity of fat that determines 

 the gain, but the relation between the two, together with 

 the bodily condition. 



This being the case, we should first endeavor to ascer- 

 tain what ratio of albuminoids to fat gave the best results, 

 and then, having compounded a ration in accordance with 

 this, should endeavor to induce the animal to eat as much 

 as possible of it. Two extremes ought to be equally 

 avoided ; too much albuminoids woidd cause an xmneccs- 

 sary protein consumption in the body, while if the ration 

 contained an excess of fat, it might be impossible for the 

 animal to eat enough of it to supply himself with the 

 necessary amount of protein.
