DETAILS OF DIGESTION EXPERIMENT NO. 39. 



This experiment, representing the prehminary period of 

 metabohsm experiment No. 6, began with breakfast May 14, 

 1897, and continued four days. The subject, E. O., weighed 

 without clothes, 68.6 kilos at the beginning and 66.2 kilos at 

 the end of the experiment. During the period he worked sev- 

 eral hours each day, at his usual occupation, and riding a 

 bicycle over country roads or working a stationary machine 

 indoors. The amount of work performed was more than that 

 to which he was accustomed. The quantity of protein in the 

 diet was the same as in the preceding experiment but the 

 energy was largely increased on account of the work.

During this experiment the subject eliminated 3680.2 grams 

 urine, containing 44.6 grams nitrogen. The average nitrogen 

 balance per da}' was therefore as follows: Income in food, 

 19. 1 grams; outgo in urine, 11. i grams, and in feces, 1.9 grams; 

 implying a gain of 6.1 grams nitrogen, corresponding to 38.1 

 grams protein.
