During this experiment, the animal eliminated 134.5 lbs. 
urine, containing 1.43 lbs. nitrogen. The nitrogen balance 
was therefore as follows: Income in food 2.19 Ibs.; outgo in 
urine 1.43 lbs; and in feces .56 lbs.; implying a gain of .20 
Ibs. nitrogen corresponding to 1.25 lbs. protein. The total 
heat of combustion of the urine as determined was 6585 
calories.
