During this experiment the subject eliminated 3,604 grams urine, 

 containing- 07.26 grams nitrogen. The average nitrogen balance per 

 day was therefore as follows: Income in food 19.26 grams; outgo in 

 urine 16.82 grams; and in feces 1.89 grams; implying a gain of 0.55 

 gram nitrogen, corresponding to 3.4: grams protein,
