Remarks.—This experiment began with breakfast May 18 and continued four 
days. It represents the second period of metabolism experiment No. 6, namely, 
that passed in the respiration calorimeter. The subject entered the calorimeter 
on the evening of May 17, immediately after the close of the first period, and 
remained until 7 o’clock on the morning of May 21. The charcoal taken with 
the bread and milk for supper May 17 served to mark the separation of the feces 
between the end of the first and the beginning of the second period of this 
metabolism experiment. The following table shows the income and outgo of 
nitrogen:
