METABOLISM DURING WALKING.

 days), 116.5 mm. 



being 20.6. (See table 3, p. 43.) In the other standing experiments, 

 the respiration-rate varied from 14.9 to 16.6, with averages on April 10 

 and 17, 1915, of approximately 15.5. Undoubtedly on the first day 

 (March 20) the subject was under considerable mental excitement and 

 the respiration-rate recorded for this day was probably not normal; 

 it has therefore been omitted in calculating the average. The data in 

 table 3 (p. 43) give no marked evidence of a change in the respiration- 

 rate in any one direction from period to period or from day to day, 

 though it might be said that there was a tendency for the respiration- 

 rate to be lower during the later periods of the day. 



The respiration-rate of T. H. H. shows a slight tendency to increase 

 from period to period on the days when standing experiments were 

 made with this subject. The daily average varied from 12.7 to 13.2, 

 with a general average of 12.9 for the series. 



The average respiration-rate for the day varied with W. K. from 

 18.1 on March 17 to 24.9 on March 12, 1915, with an average for the 

 entire series of 21.1. (See table 5, p. 44.) There was no marked change 

 one way or the other in the rate from period to period as the standing 

 continued. It might be said that frequently the highest values were 

 obtained during the first period of the several experiments. No 

 tendency is shown towards a decided difference in the respiration-rates 

 obtained in the early experiments in February and March and those 

 recorded in the later experiments, the average for February and March 

 being 21.1 and that for May and June 21.2. 



E. D. B. had the lowest initial daily respiration-rate of any of the 

 subjects. His average rate varied from 12.3 on October 4 (the first 

 record) to 16.7 on November 29, 1915. An inspection of table 6 

 shows that there is a slight tendency for the respiration-rate to increase 

 in the succeeding periods of the forenoon. This increase is not large
