other experiments it is apparent from the urine values that the sub- 

 jects have hved before the experiments on a diet rich in nitrogen and 

 the comparison of the feces belonging to the meat days with those 

 from the preceding diet is therefore of little value. 



B. W. in exp. Ill is an exception. The nitrogen content of the 

 urine shows that he has not lived on a meat diet on the two days pre- 

 ceding the experiment and the feces for this period show 6.1 gr. N 

 per day as compared with 4.2 gr. for the meat days. 



The nitrogen excretion through the gut is on almost all days 

 higher than that observed on civilized people. 



Column 5 shows the amount of Л' per day available for cata- 

 bolism and col. 6 the amount found in the corresponding urine. The 

 ingestion of food began in all cases except exp. IV ^^/g at about 9 a. m. 

 and the excretion of N in the urine began to rise shortly afterwards 

 (at 11 to 12), but the increase was not considerable at first. The 24
