During this experiment, the animal eliminated 95.3 lbs. 
urine containing 1.12 lbs. nitrogen. The nitrogen balance 
was therefore as follows: Income in food 1.82 lbs.; outgo 
in urine 1.12 lbs., and in feces .60 lbs.; implying again of .10 
Ibs. nitrogen corresponding to .625 lbs. protein. 
* Calculated from dlgestible protein.
