Approximation in whites {after Quetelet, Vierordt, and others) 



Stature, 90 to 99.9 cm., corresponding to ages 3i to 5 years, respectively 27 to 25 per minute 



Stature, 110 to 150 cm., corresponding to ages 6] to 14 years, respectively 25 to 20 per minute 



Stature, 150 to 170 cm., corresponding to ages 15 to 20 years, respectively 22 to 18 per minute 



Adults, respectively 16 to 19 per minute 



The intertribal difference in the frequency of respiration is as 

 follows : 



Excess in average rate of respiration in Pima over Apache, by main stature groups 



These differences seem to diminish somewhat with age, but as will 

 be seen from other data, a trace of them persists to adult life. They 

 are too regular to be attributed to the operation of chance, and, in the 

 absence of apparent cause, they must be regarded as a natural 

 condition.
