Detailed data of income and outgo. — The quantities of nutrients in 
the basal ration which were used for the experiments and the quantities 
in the supplemental ration in the two experiments are shown in Table 
99. The elimination of matter and energy in the feces was determined 
in each experiment and the results are recorded in Table 100.

The usual statistics of outgo of nitrogen, carbon, hydrogen, water, 
and energy in the urine are given in Tables 101 and 102. The urine 
was collected in the usual periods for twenty-four hours following the 
close of experiment No. 28. The elimination of nitrogen in these 
periods was 3.48, 5.25, 4.74, and 2.96 grams, respectively, or a total of 
16.43 grams.
