Wliile with a small ration of meat the animal lost both 

 flesli and fat, a medium ration (1,500 grammes) sufficed to 

 stop the loss, not only of flesh but also of fat, and larger 

 amounts, while they could not, for tlie reasons explained 

 in the preceding chapter, cause any considerable gain of 

 flesh, did cause a gain of fat ; i, ^., not only did the albu- 

 minoids protect the body-fat from oxidation, but new fat 

 was formed from them and laid up in the body. 



These results are most simply explained by the assump- 

 tion that the fat formed in the body from albuminoids, 

 like that contained as such in the food, is more readily 

 oxidized than that already stored up in the body. 



Incidentally these experiments give proof of the possi* 

 bility of the formation of fat from protein, and also of the 

 statement just made that a gain of fat may accompany a 

 loss of flesh.

Protein protects, the Fat of the Food from Oxi- 

 dation. — Since in the fodder of herbivorous animals fat is 

 usually present in small quantity, and is of comparatively
