l The pulse-rate at 8P 35" a.m. was 64. 
J The machine was driven by motor. There was considerable strain on the subject's arms, and he complained 
at the end of the experiment that his arms were practically useless, particularly his wrists. He rode 
the motor-driven machine between periods at practically the same speed as during the periods.

1 The subject lay down at 8 a.m. The pulse-rate at & 28™ a.m. was 62; at 8>" 35" a-m., and 8>> 40" a.m., 60. 
* The subject complained that he was very cold. There was question as to whether or not he had a chilli 
though the pulse did not indicate anything very serious. 
* The riding was like that of Feb. 13, the machine being driven by means of a motor. There was no evidence 
that the subject used his muscles to rotate the disk. The motor was started at 9.59 a.m. and the sub- 
ject rode preliminary to the first period. Between the first and second "no-load" periods he rode at 
the average rate of about 90 revolutions per minute; between the second and third periods at the 
average rate of about 92 per minute; between the third and fourth periods at the average rate of 
about 97 per minute. 
4 One record at the wrist. 
6 The chain was slack during both the second and the third "no-load" periods. 
8 The machine was driven by the subject, not by the motor. 
7 Average of records taken at the wrist.

l The subject lay down at 8»> 05" a.m. The pulse-rate at 8>> 28" a.m., 8 h 33" a-m., and 8>> 36" a.m., was 62. 
* The motor to drive the machine was started at &> 54" a.m. Preliminary to the first "no-load" peiiod, the 
subject rode at the average rate of 94 revolutions per minute. The chain was slack during the period. 
» The chain was slack. The subject found this kind of experiment a tremendous strain on his hands and 
arms. The average speed in the interval before this period was 90 per minute. 
* The chain was slack. The average speed in the interval before the period was 93 revolutions per minute. 
* At ll h 14" a.m. the subject began riding without the motor drive. The average speed from ll h 14" a.m. 
to the beginning of the period at ll h 24" a.m. was 99 revolutions per minute. 
6 The average speed in the interval before this period was 93 revolutions per minute.
