During this experiment the subject eliminated 6,385 grams urine, 

 containing 1«)7,13 grams nitrogen. The average nitrogen ))alance per 

 day was therefore as follows: Income in food, 30.01 grams; outgo in 

 urine, 26.78 grams, and in feces, 2.32 grams, implying a gain of 0.91 

 grams nitrogen, corresponding to 5.7 grams protein. 



DIGESTION EXPERIMENT NO. 248. 



Kind of food. — Milk, and bread made from straight patent flour. 



Subject. — University student Mo. 1. 



Weight. — At the beginning of experiment, 164 pounds; at the close, 

 164 pounds. 



Duration. — Four days, with twelve meals, beginning wdth breakfast 

 May 1, 1901. 



Table 12. — Results of digestion experiment No. 248. 



a Estimated on the assumption that 90 per cent of the fat in bread is digestible. 



During this experiment the subject eliminated 4,378 grams urine, 

 containing 85.44 grams nitrogen. The average nitrogen balance per 

 day was therefore as follows: Income in food, 23.79 grams; outgo in 

 urine, 21.38 grams, and in feces, 1.82 grams, implying a gain of 0.59 

 gram nitrogen, corresponding to 3.7 grams protein.
