1 See table 42 for experiment on January 2, 1912. 
* During the interval there were 28 minutes of hard work followed by 14 minutes of work at 60 revolutions per 
minute. The records of speed at &* 52™ a.m. and 10 11 12™ a.m. were 95 and 98 revolutions per minute. 
Second wind after 16 minutes. Pulse-rate during the preliminary work with the speed at 60 revolu- 
tions was 145, 124, 128. 
1 Approximate. 
* The subject had 5 minutes' complete rest sitting on the bicycle after the last experiment. He started again 
at 10 h 45™ a.m., at a speed of 60 revolutions per minute.

1 The subject lay down at 7 h 55™ a.m. The pulse-rate at &• 12™ a.m. was 68; at 8 h 16™ a.m., 66; at S>> 19™ 
a.m., 64; at S h 22™ a.m., 63. 
» Be ginnin g at 9 11 29™ a.m. the subject rode rapidly for 25 minutes at the average rate of 119 revolutions per 
minute. At 9" 1 54™ a.m. the speed was lowered to 60 revolutions per minute. The subject washed 
his mouth by gargling while riding fast. He perspired freely and felt winded just before he finished the 
fast riding. He rode fastest at first, *'. «., about 136 revolutions per minute. Second wind at 9 11 33™ a.m. 
The pulse-rate was obtained after the speed was decreased as follows: at 9 h 59™ a.m., 152; at 10* 05™ 
a.m., 144; at 10 11 09™ a.m., 144. During the period itself there were symptoms of collapse at the end 
of 7.5 minutes and the period was therefore ended as soon as possible. There was twitching of the 
subject's lips but no leak. 
* There was a possible trace of carbon dioxide in the circuit by test. 
* Approximate. The metronome set at 60 was used to regulate the speed from 9 h 54™ a.m. to the end of work. 
* The subject looked all right and said he was quite ready to continue the work. The work was easily done.

1 The subject lay down at 7 h 55™ a.m. Pulse-rate at 5-minute intervals after 8 h 10™ a.m. was 66, 64, 64, 64. 
2 The subject rode rapidly for an hour after the first lying period, not breathing in the circuit of the respira- 
tion apparatus. At times he rode much more rapidly, as high as 140 revolutions per minute. Work 
was finished at 9» 50™ a.m. The subject then lay down pouring with perspiration, and was rubbed 
down. He had to rest a little and rested with his mouth on the mouthpiece from 9 h 53™ a.m. to & 55™ 
a.m., when the period began. He lay very quietly. 
* At the end of the preceding period the subject was still thoroughly bathed in perspiration. His arms and 
chest were rubbed down and his flannels were removed for comfort.
