During this experiment, the animal eliminated 98.7 Ibs. 
urine containing 1.38 lbs. nitrogen. The nitrogen balance 
was therefore as follows: Income in food 1.87 lbs.; outgo in 
urine 1.38 lbs.; and in feces .50 lbs.; implying a loss of .01 
Ibs. nitrogen corresponding to .063 lbs. protein. The total 
heat of combustion of the urine as determined was 7597 
calories.
