1 Work was begun at 9 1 19" a.m. Between Sf 1 19" a»m. and 8^ 49™ a.m. the average speed was 71 revolu- 
tions per minute. The work was done without strain and the perspiration was slight. 
* At & 02™ a.m. the pace was changed to 100 revolutions per minute. Between 9* 02 m a.m. and 9* 20™ a.m. 
the average speed was approximately 95 revolutions per minute. Perspiration was profuse. 
* In the interval before this period the average speed was 104 revolutions per minute. During the period the 
work was easily done. The subject perspired freely. 
* At 9 1 " 51 m a.m. the current was decreased to 0.5 ampere and the speed to 70 revolutions per minute. Between 
9 1 51™ a.m. and lO 1 " 17™ a.m. the average speed was 70 revolutions per minute. During the fourth 
period the work was done without effort of any kind. There was no perspiration. The pulse-rate 
before this period was at lO 1 " 10™ a-m., 92; at 10 h 16™ a.m., 94. 
5 At 10* 30™ a.m. the speed was increased to 100 revolutions per minute. The average speed from 10 h 30" 
a-m. to the beginning of the fifth period was 82 (?) revolutions per minute. 
8 The average speed in interval before the period was 90 revs, per min. During period the work was done with 
comparative ease, but subject was glad when it was finished. No perspiration.
