1 Ergometer I was used for all experiments to January 19, 1912, inclusive; ergometer II was used in all 
experiments subsequent to that date. 
2 Determined in respiration experiment of April 6, 1912. The corresponding respiratory quotient was 0.81. 
3 Assumed from results obtained with this subject in respiration experiments made Jan. 4, to April 25, 1911. 
The corresponding respiratory quotient was 0.84. 
4 Determined in respiration experiment of April 4, 1912. (See table 35.) 
6 Determined in a series of respiration experiments made Jan. 9 to 13, 1912. The corresponding respiratory 
quotient was 0.86. 
• Determined in respiration experiments of Feb. 12 and April 6, 1912. Corresponding respiratory quotient 0.86. 
V Determined in respiration experiment of March 14, 1912. The corresponding respiratory quotient was 0.84. 
8 This figure is a general average of results obtained with this subject while lying on the couch before work. 
(See table 91.)
