STATISTICS OF EXPERIMENTS. 



29 



with intermissions ranging from 11 to 19 minutes. The experiment began at 



8 h 13 m a. m., and ended at 9 h 39 m a. m. The subject was instructed not to go 



to sleep and apparently did not; in the second period he was uneasy, moving his 



legs and changing his position somewhat several times. In the third period 



the observer thought the subject opened his mouth and moistened his lips, but 



he himself thought he did not. The results of the experiment are given in 



table 19.

1 One record of pulse. 



2 Carbon dioxide eliminated per kgm. perminute, 2.41 c.c; oxygen absorbed per kgm. per minute, 



3.21 c.c. The 100c. c. of urine collected between 6" 45 m a.m. and 9 h 45 m a.m. contained 1.56 gm. 

 nitrogen and 1 gm. sugar. 



Calorimeter Experiment M2. 



Date, June 15, 1911. Body-weight without clothing, 82.9 kilos. 



The subject came to the laboratory without breakfast at 7 h 25 ra a. m., 

 entered the bed calorimeter at 7 h 56 m a.m., and the experiment began at 8 h 52 m 

 a. m. Three periods, one of 53 minutes and two of 45 minutes, were included 

 in this experiment. Except in the second period, when he rolled over on his 

 side and used his arms considerably in handling the newspaper he was reading, 

 the subject was very quiet all through the experiment. Afterwards he said he 

 was very comfortable while in the apparatus and suffered no discomfort. The 

 metabolism measurements are given in table 20. 



! Carbon dioxide eliminated per kilogram per minute, 2.29 c.c: oxygen absorbed per kilogram per minute, 2.93 c.c 

 The urine collected between about 10 h 30 m p.m. June 14 and 12 h 15 m p.m. June 15, specific gravity 1.025, amounted 

 to 335 c.c. and contained 4.12 gms. of nitrogen and 3.6 gms. of sugar.
