During this experiment the subject eliminated 5,372 grams urine, 
containing 0.589 per cent or 31.63 grams nitrogen. The average 
nitrogen balance per day was therefore as follows: Income in food 
7.81 grams; outgo in urine 7.91 grams, and in feces 2.35 grams; 
indicating a loss of 2.45 grams nitrogen, corresponding to 15.31 grams 
protein.
