1 The subject had eaten a light breakfast at 6 h 50 m a.m., consisting of 2 scrambled eggs, about 125 grams of 
o ™ br ead, about 200 c.c. of milk, and an apple. At 8 1 ' 30 m a.m. he took 50 grams of cane sugar in water. 
2 The subject lay down at 9 h 05 m a.m. The pulse-rate at 9 b 18 m a.m. was 64; at 9 h 22 m a.m., 62; at 9 h 27 m a.m., 
64. Respiration at 9 h 19 m a.m. was 22. 
3 Work was begun at 10 h 30 m a.m. Between 10 h 30 m a.m. and 10 h 40 m a.m. the average speed was about 59 
revolutions per minute. The pulse-rate at 10 h 33™ a.m. was 118; at 10 h 35 m a.m., 124; at 10 h 37 m a.m.. 
124; at 10h 39™ a.m., 126. 
4 In the interval between periods the average speed was about 64 per minute. Second period was stopped after 
4 minutes of work because of the condition of the subject. There were all the signs of impending col- 
lapse. Pulse-rate suddenly became rapid. 
6 The subject was transferred from the ergometer to the couch as rapidly as possible, and lay there 11 minutes, 
i. e., 14 minutes in all from the end of work to the beginning of the first lying period. He was now in 
good condition. The pulse-rate at ll h 15 m a.m. was 76; at ll h 17 m 30 s a.m. it was 72.

1 Work was begun at 8 h 34™ a.m. Owing to a fault in the counter, it is uncertain how rapidly the riding was 
done up to the begi n ning of the period. The probable speed was 54 per minute. 
2 Approximate. 
3 In the interval before this period the average speed was probably about 54 per minute for the time between 
9 b 17 m a.m. and 9 h 28 m a.m. 
4 The current was lowered from 1.5 amperes to 0.5 ampere at 9 h 40 m a.m. Between 9 h 40 m a.m. and 9 b 57m 
a.m. the average speed was 76 per minute. The subject was troubled by soreness in his knees, and 
said it was much easier for him to ride fast than slowly, because his knees pained him less. 
6 In the interval before this period the average speed was 78 per minute.

1 Work was begun at 8 h 25 011 a.m. Between 8 h 25 m a.m. and 9 a.m. the average speed was 73 per minute. 
The pulse-rate at 8 h 56 m a.m. was 88. The subject was annoyed by saddle soreness during the period. 
2 In the interval before this period the average speed was 70 per minute. At 9 h 33 m a.m. the covering which 
had been placed on the saddle slipped off. 
3 The current was raised to 1.5 amperes at 9 h 38 m a.m. Between 9 h 38 m a.m. and 10 h 06™ a.m. the average 
speed was 62 per minute. The pulse-rate at 9 h 50 m a.m. and at 9 h 57 m a.m. was 124. The subject said 
after the period that he was very tired. 
4 In the interval before this period the average speed was 62 per minute. During the period the work was 
done without any apparent difficulty, though the subject said at the end that he was much exhausted 
and very hungry. 
8 Record of pulse-rate at 10 h 31 m a.m. Work was finished at the end of the period, and one-half minute later 
the pulse-rate was 116.
