Detailed data of income and outgo. — The quantities of nutrients 
in the basal and supplemental rations during 1 this series of experi- 
ments are shown in Table LI 5. The outgo of matter and energy 
in the feces during the successive experiments is shown in Table 11(3. 
Tables 117 and 118 show the amount and composition of the urine in 
experiments Nos. 29 and 31.
