Remarks.—This experiment began with breakfast May 4, 1897. It repre-. 
sents the second period of metabolism experiment No. s, namely, that passed in 
the respiration calorimeter. The subject entered the calorimeter on the evening 
of May 3 and remained until 7 o’clock on the morning of May 8, when the experi- 
ment ended. ‘The separation of the feces was made with supper on May 3, the 
close of experiment No. 37. Consequently one separation marks the end of the 
first and the beginning of the second period of the metabolism experiment. The 
following table shows the income and outgo of nitrogen in this experiment.
