' Omitted from averages. 



From the above data a calculation is made of the total ainoniits of 

 food nutrients iu the carcasses of the sheep killed at the beginning' and 

 close of the experiment. 



"Ill the dry matter of flesh there was in each group an increase in the fat and a 

 corresponding decrease in protein and ash. These differences were greater in the 

 wide ration group. 



"The chief differences in composition between tlie different groups, when calcu- 

 lated to fresli substance of flesh, are still due to the fat. One of the facts brought 

 out very early in our study of the compo.sitiou of animal foods was, that water and 

 fat to a very great exteut replace each other. This is stiiknigly shown in the com- 

 position of the flesh of the animals of the wide and narrow rations. The protein is 

 nearly the same in each, while the flesh of the narrow-ration animals contains 1.5 

 lbs. per 100 more water and 1.6 lbs. per 100 less fat than that of the wide-ration 

 group. ' 



The work is being continued.
