 Digestion experiment No. ^5. 



During this experiment the subject eliminated 5104.2 grams 

 urine, containing 77.6 grams nitrogen. The average nitrogen 

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

 18.9 grams; outgo in urine, 19.4 grams, and in feces, 1.7 

 grams; implying a loss of 2.2 grams nitrogen, corresponding to 

 13.8 grams protein.
