METABOLISM EXPERIMENTS NOS. 23 AND 24. 
These experiments were consecutive and form the hist of the experi- 
ments of L898-99. 
Subject. — E. O., as in experiments Nos. 11, 13, and L4, described 
above. 
Occupation during experimsiit. — Reading, writing, etc., with as little 
muscular and mental activity as practicable. 
Duration. -Three days each. Experiment No. % 2?> began at 7 a. m., 
March It;, and ended at 7 a. in.. March 19, at which time experiment 
No. 24 began and continued 3 days. An experiment not here re- 
volted immediately preceded experiment No. 23, so that the subject 
actually spent 9 days in the respiration calorimeter. The usual pre- 
liminary period preceded the whole series of experiments. 
Diet.- The diet consisted of a basal ration of beef, butter, milk, 
bread, parched cereal, sugar, and horseradish, furnishing 124 grams 
of protein and 2,546 calories of energy per day. This basal ration
