66 A BIOMETRIC STUDY OF BASAL METABOLISM IN MAN. 



are made upon a series of individuals from which physically and men- 

 tally abnormal men were not excluded, and (6) that the rates were taken 

 with the convict sitting in his cell, writing, reading, or doing nothing 

 about 15 minutes after early dinner instead of 12 hours after the last 

 meal and in a state of complete muscular repose.

Korosy's data for conscripts 76 are physiologically more nearly com- 

 parable with our own. They were taken on a group from which all 

 individuals not having a perfectly healthy heart had been excluded. 

 The countings were made in the early morning soon after the men 

 were wakened and while they were still in a position of rest. The 

 constants deduced by Bell 77 are compared with our own as follows : 



K6rosy's series. Our series. Difference. 



Mean 64.212.71 61.260.41 2.952.74 



S.D 8.490.36 6.730.29 1.760.46 



C. V 13.22 0.40 10.99 0.48 2.23 0.62 



These results are in much closer agreement with our own than the 

 determinations on convicts; but means, absolute variabilities, and 

 relative variabilities are larger than in our series. 



Since pulse-rate is a physiological measure well known to be affected 

 by other physiological factors, we take these facts to indicate that our 

 records for pulse-rate and in consequence those for metabolism as 

 well, for both were measured simultaneously have been determined 

 under conditions which introduced the minimum external influence. 



Turning to a more detailed examination of our own constants, we 

 note that the w r omen have a more rapid and more variable pulse than 

 the men. The averages are :
