the rectal thermometer. The subject also used a clinical thermometer at 

 ll h 10 m a. m., 12 h 10 m p. m., and l h 10 m p. m. In this and the succeeding 

 experiments an attempt was made to obtain some record of the muscular 

 activity of the subject by the use of a pneumatic cushion connected with a 

 kymograph. Throughout the experiment there was but little muscular move- 

 ment aside from the activity incidental to telephoning several times during

each period, and drinking 64 c.c. of water at 10 h 20 m a. m. Previous to the 

 experiment the subject urinated and defecated at 8 h 15 m a. m., and urinated 

 again at l h 20 m p. m. after the experiment was over, but was unable to urinate 

 during the experimental period. The records of the experiment are given in 

 tables 100 and 101.

Calorimeter Experiment No. X2. 



Date, March 1, 1910. Body-weight without clothing, 62.7 kilos. 



With the exception of a cup of coffee, no food was taken by the subject 

 before he came to the laboratory at 7 h 50 m a. m. At 8 h 08 m a. m., the subject 

 entered the chair calorimeter; the experiment began at 9 h 18 m a. m., continued 

 for three 1-hour periods, and ended at 12 h 18 m p. m. The records of the pulse 

 and respiration rates were obtained as in the preceding experiment, but the 

 rectal thermometer was not used, although records were taken by the subject 

 with a clinical thermometer at 9 h 28 m a. m., 10 h 32 m a. m., ll h 28 m a. m., and
