Remarks.—This experiment began with breakfast June 8, 1897, and con- 
tinued four days. It represents that period of metabolism experiment No. 7 
which was passed in the respiration calorimeter. The subject entered the calo- 
rimeter the evening of June 6 and remained until 7 o’clock the morning of June 
12. The diet included 290 grams of absolute alcohol, 12 grams of which were 
eliminated from the body unchanged during the four days of the experiment. 
The subject was very quiet while in the respiration chamber, moving around no 
more than was necessary. The diet was so small in amount and in bulk that, 
both in this and the first period, he experienced some hunger, The following 
table shows the income and outgo of nitrogen in this experiment:
