During this experiment the subject eliminated 9272.5 grams 

 urine, containing 78.0 grams nitrogen. The average nitrogen 

 balance per day was therefore as follows: Income in food, 

 20.8 grams; outgo in urine, 19.5 grams, and in feces, 1.3 

 grams; implying that there was neither a gain nor a loss of 

 nitrogen.
