1 The pulse-rate at & 40=° a.m. was 72; at &> 45™ a.m., 8 h 48™ a.m., and 8 h 51™ a.m., 70. 
* Work was begun at Kfr 20™ a.m. The work was continuous to the beginning of the period and at practically 
the same speed. The pulse-rate at 10 11 19™ a.m. was 72. The pulse-rate at 10 11 26™ a.m. was 134; at 
10>> 31™ a.m., 152. 
* Approximate. 
* Between the two periods here recorded another work-period was attempted, but it was lost owing to slip- 
ping of the noseclip. The pulse-rate at ll h 13™ a.m. was 174. During the period the subject did not 
appear to work quite so readily. The pulse-rate became very rapid. 
* The subject lay on the couch soon after the work was finished. The pulse-rate fell slowly. At ll h 44™ 
a-m. it was 100; at ll h 52™ a.m., 88; at ll h 56™ a.m., 88; at 12 noon, 84.

I The subject drank a chocolate milk-shake at 8 a.m. 
* One record of pulse and respiration in each period. 
* Work was begun at l h 19™ p.m. The counter was out of order, however, and had to be repaired. Work 
was begun again at l h 34™ p.m. The average speed to the beginning of the first period was approxi- 
mately 60 revolutions per minute. During the period the work was done with considerable effort. 
4 In the interval before this period the average speed was 64 per minute. During the period the work was 
done with difficulty. 
* The current was lowered to 0.5 ampere at 2 h 32™ p.m. Between 2 h 32™ p.m. and 2 h 49™ p.m. the average 
speed was 88 per minute. During the period the work was done with comparative ease. 
6 In the interval before this period the average speed was 69 per minute. During the period the work was 
on the whole a trifle labored.

1 One record of pulse and respiration in each period. 
* See table 31 for experiment on November 23, 1911. 
* Work was begun at 8* 57™ a.m. Between 8* 57™ a.m. and 9 h 13™ a.m. the average speed was 65 revolu- 
tions per minute. 
* During this period the work was easily done. Subject said the work was not very heavy. During the 
interval before the period the speed was practically at the constant rate maintained throughout the 
periods of the day. 
t Immediately at the close of the preceding period the current was lowered from 1.5 amperes to 0.5 ampere. 
In the interval before the period the average speed was practically at the constant rate for the day. 
* In the interval before this period, the average speed was 63 per minute. After this period was completed 
the subject tried bis "capacity to work" at 1.5 amperes. He rode at the rate of 104 per minute for 
several minutes.
