1 The subject complained that he felt stiff and tired and had no particular inclination to work. He did not 
feel like " breaking any records." He lay very quietly. 
* He lay very still. There was some disturbance because of several people coming into the room toward the 
end of the period. His attention was also taken up with preparations being made for taking samples 
of his alveolar air. 
* Work was begun at 9* 20" a.m. Between 9 11 20" a.m. and 9"> 32" a.m. the subject rode at the average speed 
of 95 revolutions per minute, though for the first 5 minutes he rode at the rate of 114 revolutions per 
minute. Carbon dioxide was found to be passing the absorbers at 9 11 40" a-m. because of very poor 
soda-lime. The subject had all the symptoms of impending collapse. He said he could go on, but 
the period was ended. 
« Between the two periods the subject rode at the average rate of 76 revolutions per minute, more rapidly at 
first. At 10 h 07" a.m. he rode 94 revolutions in one-half minute. At lO* 1 24" a.m. carbon dioxide was 
detected passing the absorbers. The subject was not looking well, and the period was therefore ended. 
As in the preceding period the soda-lime was found to be poor. 
5 Work ceased at lO 1 " 25" a.m. The subject felt very hungry at about 10 p.m. the night before. He felt 
tired when rising time came, and lacked energy. During the week he felt very tired and was disin- 
clined to exert himself. In the half minute (10 h 07" a.m.) in which he did exert himself, the effort was 
too great. He could not work as hard as usual and felt that he had somehow lost his strength. He 
was very hungry. Samples of his alveolar air were taken at about 10" 1 10" a.m. during work and at 
10 11 26" a.m., lO* 45" a.m., ll h OS" a.m., ll b 30" a.m., and ll h 57" a,m., after the work was finished.

1 Between the first and second periods samples of alveolar air were taken, causing the subject to move his 
body somewhat on the couch. The same movements of the body occurred on Jan. 18, when the samples 
were taken. 
J Work was begun at 9* 52" a.m. Between 9>> 52" a.m. and lO* 1 05" a.m. the subject rode at the average 
speed of 94 revolutions per minute, during the first 5 minutes at the rate of 113 revolutions per minute. 
He found the work extremely hard and fatiguing and thought he had broken all his previous records. 
* Between the two periods the subjectrode at the average speed of 68 revolutions per minute. At about 
10 11 30" a.m. he rode 98 revolutions in 30 seconds. The work was apparently laborious. The sub- 
ject was positive that he was doing far harder work on this day than on earlier days when his diet wa3 
varied in character. He denied that he would not work because he thought the food was not right for 
him. He said that he was putting forth the best that was in him. The subject felt more tired than 
ever after work. 
* Work ceased at lO* 59™ a.m. Between 5 and 10 minutes later samples of alveolar air were taken. A num- 
ber of samples of alveolar air were taken during the day while the subject was lying before work, sitting 
on the ergometer before work, during work, and while lying after work.
