1 The subject lay down at &> 07 m a.m. The pulse-rate at 8 h 25 m a.m. was 64; at 8 h 35 m a.m., 64. 
* Work was begun at 9 h 47 m a.m. Between 9^ 47 m a.m. and 10 11 03 m a.m. the subject rode at the average rate 
of 109 revolutions per minute. 
* In the interval before this period the average speed was 84 revolutions per minute. 
* In the interval before this period the average speed was 81 revolutions per minute. The full 10 minutes 
for the period were not completed as the subject was manifestly fatigued. He admitted at the end of 
the period that he was much exhausted. 
5 At 10 h 56^ a.m. the current was lowered to 0.95 ampere. Between 1(P> 56 m a.m. and ll h 06 m a.m. the 
average speed was 76 revolutions per minute. 
6 In the interval before this period the average speed was 83 revolutions per minute. 
1 In the interval before this period the average speed was 77 revolutions per minute. The subject had now 
fully recovered from his hard work. During the two preceding periods at 0.95 ampere, however, he 
was still feeling the effect of the previous hard work.

1 Work was begun at 8 h 15 m a.m. without preliminary lying periods. Between 8J 1 15 m a.m. and 8*" 48 m a.m. 
the subject rode at the average rate of 120 revolutions per minute. It was difficult to keep him from 
racing. The plan was to keep the speed practically constant throughout the day. 
* In the interval before this period the average speed was 95 revolutions per minute. 
3 From the end of the preceding period to 9 h 49 m a.m. the subject rode at the average rate of about 99 revo- 
lutions per minute. At 9 h 49 m a.m. the current was increased to 1.5 amperes and the handle bars were 
raised. The raising of the handle bars helped his wrists and arms. Between 9 h 49 m a.m. and lO 1 " 09" 
a.m. the subject rode at the average speed of 94 revolutions per minute. There was again a tendency 
to race. Sweating was somewhat profuse. 
* In the interval before this period the average speed was 82 revolutions per minute. 
5 In the interval before this period the average speed was 120 revolutions per minute. There was still a ten- 
dency to race. 
« At 10 b 57 m a.m. the current was lowered to 0.5 ampere. Between 10 11 57 m a.m. and ll h 12 m a.m. the average 
speed was 96 revolutions per minute. It was constantly necessary to restrain the subject in order to 
prevent overspeeding. 
1 In the interval before this period the average speed was 87 revolutions per minute. 
8 In the interval before this period the average speed was 89 revolutions per minute. Dr. W. G. Anderson 
was present during the period and the subject's speed could not be checked so readily. He was in- 
clined to ride fast and "show off." Dr. Anderson examined the subject.
