DISCUSSION OF RESULTS.

The values found by Dr. Carl Tigerstedt for subject I in the standing 

 position, which was the only position used by Dr. Tigerstedt in deter- 

 mining the basal metabolism of this subject, are given in table 6. Since 

 the walking experiments were made in the morning and in the afternoon 

 and with and without food, the basal values were also obtained in both 

 the post-absorptive condition and after the taking of food. The appa- 

 ratus used for determining the respiratory exchange was the same as 

 that employed for the walking experiments.

Values per minute.] 



As will be seen from table 6, the average post-absorptive values are 

 reasonably constant throughout the entire period from November 28 

 to December 20. A striking exception is shown oh December 5, when 

 the average carbon-dioxide excretion was 236 c.c. per minute and the 

 oxygen consumption 334 c.c. per minute. The protocols for this 

 experiment show that "there was no sleep the night before, but much 

 alcohol." The pulse-rate was especially high on this particular day. 

 The general average for the observations without food shows a carbon- 

 dioxide excretion of 223 c.c. per minute and an oxygen consumption of 

 280 c.c. per minute. This corresponds to a heat output of 1.34 calories 

 per minute. The pulse-rate of this man was extremely high, averaging 

 94 beats per minute; the average respiration rate was 21.2 per minute. 



All of these experiments were made with subject I standing with 

 muscles relaxed. The general uniformity of the data shows that for 

 the most part the subject must have assumed a standing position with 

 a relatively constant muscle strain, although variations are found in
