1 Work was begun at 2 p.m. Between 2 p.m. and 2 h 31" p.m. the average speed was 74 revolutions per minute. 
The pulse-rate in the preliminary period before the mouth was put to the mouthpiece was at 2 h 07 m p.m. 
148; at 2 h 19™ p.m., 168; at 2 h 26" p. m., 166. The subject's mouth was put to the mouthpiece at 
2* 27 m p.m. The pulse-rate at 2 h 28" p.m. was 166. During the period work was first done rather 
easily, but later with more difficulty. The subject's breathing was labored at the end of the period. 
The saddle was uncomfortable. The pulse-rate 2 minutes after the close of the period was 146. 
* In the interval before this period the average speed was 63 per minute. During the period work was done 
with comparative ease. Perspiration was profuse. 
» The current was lowered to 0.5 ampere at 3>> 02" p.m. In the interval before this period the average speed 
was 65 per minute. The pulse-rate in this interval was at 3 h 20 m p.m., 132; at 3*" 26 111 p.m., 130. 
* In the interval before this period the average speed was 56 per minute.

J The subject lay down at &> IS" 1 a.m. 
* The respiration-rate while the subject was on the couch was for the full period as recorded by the spirometer. 
* Work was begun at 8>> 26™ a.m., the average speed between this time and 8k 5^ a.m. being 75 revolutions 
per minute. The subject started riding all right, beginning to perspire in about 10 minutes, but dur- 
ing the experimental period, he was in great distress, his Tips moving backward and forward on the 
mouthpiece with each respiration. The period was ended because of the condition of the subject. He 
complained of saddle soreness and shortage of air. Perspiration was very profuse. 
* In the interval before this period, the current was lowered to 0.5 ampere. The subject rested after the first 
period. He rode a total of about 2,556 revolutions between the end of the first period and the begin- 
ning of the second. _ During the second period the work was easily and readily done. 
C In the interval before this period the average speed was apparently about 51 revolutions per minute. Dur- 
ing the period the work was done with ease. The subject felt rather tired at the end of the experiment.

l Approximate. * See table 37 for experiment on December 14, 1911. 
1 The subject sat on the ergometer at &> 40^ a.m. and began riding. The metronome was used, set at 60 per 
minute. The counter was not used. The pulse averaged about 84 during the preliminary riding. 
* The subject rode very easily. He said the lack of resistance was rather disagreeable. 
* The metronome was used, set at 60. Current was on at 10 h 57 m a.m. Pulse-rate during preliminary work 
100, 104 and 106. Mouth put to mouthpiece at ll h 07" a.m. The work was done with comparative 
ease, with no marked perspiration or flushing, but the subject found it very hard after coasting.
