During this experiment, the animal eliminated 110.9 lbs. 
urine containing 1.14 Ibs. nitrogen. 
was therefore as follows: 
The nitrogen balance 
Income in food 2.34 lbs.; outgo 
in urine 1.14 lbs.; and in feces .44 lbs.; implying a gain of 
.76 Ibs. nitrogen corresponding to 4.75 Ibs. protein. The 
total heat of combustion of the urine as determined was 
4.94.2 calories. 
* Calculated from digestible protein.
