During this experiment, the animal eliminated 106 5 
lbs. urine containing 1.23 lbs. nitrogen. The nitrogen bal- 
ance was therefore as follows: Income in food 1.85 lbs.; 
outgo in urine 1.23 lbs.; and in feces .58 lbs.; implying again 
of .04 lbs. nitrogen corresponding to .25 Ibs. protein. 
* Calculated from digestible protein.
