PULSE-RATE.

The average durations of the pulse cycles for standing preliminary 

 to the walking transition, estimated as for Squad B, page 431, are as 

 follows: Bro, 0.86; Can, 0.82; Kon, 1.19; Gar, 1.38; Gul, 0.96; Mon, 

 1.02; Moy, 1.16; Pea, 1.05; To?n, 0.76; Vea, 1.16. The differences 

 between these standing pulse-cycle durations and those for the mini- 

 mum duration, which immediately follows the change to walking, 

 range from 0.11 second for Bro to 0.55 second for Gar, with an average 

 change for the squad of 0.24 second. Comparing these standing pulse- 

 cycle durations with the durations which would correspond to the 

 pulse-rates after the sixth and twenty-fourth minutes of walking, we 

 find that the average change has been to shorten the duration 0.15 

 second for 6 minutes of walking and 0.20 second for 24 minutes of 



walking. 



The average durations of the pulse cycles for Squad A just before 

 walking ceased are found from the curves to be as follows: Bro, 0.81; 

 Can, 0.81; Kon, 0.88; Gar, 0.96; Qui, 0.77; Mon, 0.81; Moy, 0.94; Pea, 

 0.92; To7n, 0.65; Vea, 0.94. Comparing these figures with the dura- 

 tions at the tenth, twentieth, and thirtieth cycles after walking ceased, 

 as was done with Squa B, we find that the average pulse cycle for
