DETAILS OF THE EXPERIMENTS. 
The details of thirteen experiments with three different subjects are 
recorded in the following- pages. The methods of calculation were in 
general the same as those described in a previous publication.* In 
many cases the derivation of the values is indicated algebraically in 
the column headings of the tables. 
METABOLISM EXPERIMENT NO. 11. 
Subject. — E. O.. the laboratory assistant who served as the subject 
in experiments Nos. 1 and 2, in which the necessary data for estimat- 
ing the income and outgo of energy were not determined. 1 ' and in 
experiments Nos. 5-10, in which these values were determined. He 
was 32 years of age. 5 feet 8 inches in height, and weighed without 
clothing about 70 kilograms (151 pounds). 
Occupation during experiment. — Worked S hours a day upon the 
stationary bicycle just described. During evenings he passed the time 
in reading, writing, and resting. 
Duration. — Four days, beginning at 7 a. m. March 22. 1898. The 
preliminary period of this experiment began with breakfast March 18. 
The subject entered the calorimeter on the evening of March 21. and 
remained until 7 a. m. March 26, thus spending live nights and four 
days in the respiration chamber. 
Diet. — The diet during the experiment consisted of beef, butter, 
skim milk, bread, ginger snaps, cereal breakfast foods, sugar, and 
coffee, and furnished 124 grams of protein and 3. $62 calories of energy 
per day. This experiment was intended to be much the same as exper- 
iment No. 9, d with the exception that the diet should furnish a con- 
siderably larger amount of energy, and a considerable amount of 
muscular work should be performed each day. The kinds and quanti- 
ties of food served at each meal were as follows:
