differ from the hay because I was compelled to, due to the fact that 
the orts had all been used for other determinations. The total 
amount of the orts was small. 
§64. The total heat consumed as dry matter by the three 
sheep was 49,585,495 calories; the total heat value of the dry mat¬ 
ter contained in the feces was 18,629,832 calories; there were ac¬ 
cordingly 30,955,663 calories appropriated by the sheep, equivalent 
to 62.43 per cent, of the energy value of the hay. By appropriated 
I mean that the energy was taken up and either stored in the body 
or eliminated in some other way than through the alimentary tract 
as undigested food. The energy escaping in the exhalations, as 
well as that contained in the urine, is included in the term appro¬ 
priated.
