Detailed data of income and outgo. — The usual statistics of income 
and outgo of matter and energy are shown in Tables 54-61, which 
follow. 
Experiments not reported here, covering 10 consecutive days, pre- 
ceded experiment No. 21. During this time the bowels were slightly 
lax. This prevented separation of the feces for the preliminary 
days from those for experiment No. 21. The total feces for 13 
da}^s are therefore recorded, as well as the average per day for this 
experiment.
