minute on the assumption that the regularity of breathing would be 

 the same throughout the rest of the minute. In lieu of longer records 

 it has been necessary to do this. The results obtained by the photo- 

 graphic method are therefore recorded only to whole numbers in table 

 110, in which the values are given for the respiration rate with the 

 subject standing before walking and those found 1, 6, 12, 24, and 26 

 minutes after the walking began. A few records taken at other 

 intervals are given in footnotes. Finally, a few values are recorded
