1 Tn? Cree u- Wa . 3 used . to 8nut off the subject's view of the rubber diaphragm. 
2 The subject's respiration was rather irregular and shallow throughout the period. Occasional deep breaths 
were taken. There was also a curious irregularity in breathing during the preceding period, extremely 
shallow. 
3 The subject desired to urinate and was in some discomfort. He was afraid to breathe deeply, as an abdom- 
_, ln {*'. breath was followed by a full movement of the diaphragm with subsequent pressure on the bladder. 
k The subject sat on the ordinary seat with his feet on unsupported pedals, t. e., with the disk perfectly free, 
o Ihe subject sat on the ergometer 20 minutes before the period. He breathed freely and deeply. His feet 
and legs were remarkably steady throughout.

1 The respiration rate was rapid at the start but was more regular than on Dec. 7. It became shallow in the 
third period. The subject desired to urinate at the beginning of the third period but did not till the 
end of the fourth period. 
2 The subject lay quietly and was comfortable. He urinated before the experiment. The heart-beat was 
steady and slow. The pulse-rate at 8 h 15 m a.m. was 76. 
3 The subject sat on the ordinary seat with his feet on unsupported pedals, i. e., with the disk perfectly free. 
4 The subject sat on the ergometer for 30 minutes before the period began. The pulse-rate at 10 h 25 m a.m. 
was 76, the subject's feet being on a foot-rest. At 10 h 27 m a.m. he lowered his feet to the pedals, and 
put his mouth to the mouthpiece. The pulse-rate at 10 h 29m a.m. was 84; at 10 h 32™ a.m., 10 h 34 m a.m., 
and 10 h 36 m a.m., it was 86; at 10 h 38 m a.m. it was 87. 
6 The subject found that sitting perfectly still was very tiring. He complained of dry air. Thia was found 
to be due to the fact that the water in the moistener was low.

1 The subject sat on the ordinary seat with his feet on unsupported pedals, i. e„ with the disk perfectly free. 
2 The subject sat on the ergometer at 8 a.m. The pulse-rate at 8 h 15 m a.m., 8 h 22 m a.m., and 8 h 28 m a.m. 
was 84. Subject put his mouth to the mouthpiece at 8 h 22 m a.m. He sat remarkably steady, and 
preferred to have his feet on the pedals rather than on the rest. In the second period the handle bars 
were uncomfortable, and later the saddle hurt him. He had a cloth covering on the saddle during the 
third period. 
3 The subject lay down at 9 h 45 m a.m. He lay perfectly quiet and was quite comfortable. 
4 The timing of the beginning of this period may not have been exactly correct, as it was difficult to follow the 
subject's breathing.
