1 See table 52 for experiment on January 10, 1912. 2 The subject lay down at 8 a.m. 
5 Work was begun at 9 h 25" a.m. Between 9 h 25" a.m. and 9 h 40" a.m. the subject rode at the average speed 
of 97 revolutions per minute, though in the first 6 minutes he rode at the rate of 136 revolutions per 
minute. During the period evidence of carbon dioxide in the circuit was found after about 6 minutes. 
The subject's speed was distinctly held down after the carbon dioxide was found to be passing the soda- 
lime. Before that the speed was well above 120 rev. per minute, rather of a strain for the subject. 
* One record, at the wrist. 
6 Between the two periods (about 32 minutes) the subject rode at the average rate of 95 revolutions per minute. 
At one time he rode 90 revolutions in one-half minute. 
« Work was finished at 10* 1 38" a.m.

1 The subject lay down at 8 h 02" a.m. The pulse-rate was 64 at S* 10", & 15", and 8 h 25" a.m. 
* Work was begun at 9 h 28" a.m. Between 9 h 2S" a.m. and 10 11 05" a.m. the average speed was 107 revolu- 
tions per minute; at times it was as high as 126 revolutions per minute. There was no difficulty of 
any kind during the period, except in keeping the subject down to a low level of work. There was 
always a tendency to sprint. 
* At the wrist. 
* Between the two periods the subject rode at the average rate of 85 revolutions per minute. It was diffi- 
cult to prevent the subject from doing too much work during this period. 
6 Work ceased at 10* 40" a.m. and the subject lay down at 10* 1 43" a.m.

1 Work was begun at 9 h 19" a.m. Between 9 h 19" a.m. and 9 h 35" a.m. the subject rode at the average rate 
of 110 revolutions per minute during the actual time of riding. In the first 5 minutes the average speed 
was 131 revolutions per minute. He stopped for a minute at 9 h 26" a.m. to urinate. The subject 
felt that he was in splendid condition. 
* One record, at the wrist. 
* Between the two periods the subject rode at the average rate of 86 revolutions per minute. 
* Work was finished at 10 h 31" a.m. There was delay in starting the first rest period because of the time 
required to remedy a leak. The apparatus was finally pronounced tight after repeated testing.
