1 The subject lay on the couch 57 minutes before the first period, because of change of gas-meters. The 
pulse-rate at 8 h 20 m a.m. was 60. 
t The subject sat on the ordinary seat with his feet on unsupported pedals, t. e., with the disk perfectly free. 
* The subject sat on the ergometer at 10 h 12 :n a.m. with feet on the rest. The pulse-rate at 10 h 25 m a.m. 
was 64. The subject placed his feet on the pedals at 10 h 25 m a.m. He put his mouth to the mouth- 
piece at 10 h 34- a.m. The pulse-rate at 10 h 33 m a.m. was 68; at 10 h 35 m a.m., 66; at 10»> 38 m a.m., 68. 
* The subject always took a very long time to settle down into his so-called resting position, as he was de- 
termined to keep his legs absolutely still during the actual period.

l The subject lav down at 8 a.m. The pulse-rate during the preliminary period was as follows: at 8 h 18 m a.m.. 
68; at 8 h 27 m a.m., 66; at 8 h 33 m a.m., 68. 
* The subject sat on the ordinary seat with his feet on unsupported pedals, »". e., with the disk perfectly free. 
1 The subject complained that the ergometer did not quite suit him. His hands became stiff, and he found 
it a great strain to sit absolutely still for 14 to 15 minutes. He did not like the "free-wheel" effect.

l The subject lay down at 8 h 05 m a-m. The pulse-rate at 8 h 25n> a.m. was 62; at 8 h 28 m a.m., 60; at 8 h 40™ 
a.m., 60. 
* The subject sat on the ordinary seat with his feet on unsupported pedals, V. e., with the disk perfectly free. 
* From 9 h 27 m a.m. to 9 h 39 m a.m., the subject sat with feet resting on the forks. He then lowered his feet 
to the pedals. He found that sitting still in this position was a constant strain. 
4 The subject began riding at 10 h 37 m a.m., the machine being driven by a motor. The belt slipped at 10 h 52™ 
a.m. The pulse-rate 15 seconds after the stopping of work due to the slipping of the beit was only 84. 
6 Between the two "no-load" periods the average speed was 72 (?) per minute. Soon after the start of the 
period (75 seconds) the belt slipped off. The machine was stopped completely, the belt was replaced, 
and the machine restarted. 
6 Work was begun at ll* 32 m a.m. with the current at 1.5 amperes. Between ll h 32°> a.m. and 11* 46= a.m. 
the average speed was 97 revolutions per minute. 
7 Pulse-rate at the end of the period. 
8 In the interval before this period, the subject rode at the average rate of 96 revolutions per minute.
