To recapitulate: The examinations of pulse, respiration, and tem- 

 perature in San Carlos Apache and in Pima children more than 1 10 cm. 

 in height (or more than about 6 years of age) show the following 

 peculiarities : 



(a) The average pulse is slower than in whites in both sexes and 

 in all the stature groups. 



Q)) There are but minor differences in the pulse rate between the 

 children of the two tribes in groups of similar height. 



(c) In both of the above-named tribes and in all groups the aver- 

 age pulse rate in the female exceeds that in the male by several 

 beats per minute. 



{a') The average frequency of respiration is about the same among 

 the Pima as among the whites, but is slightly less in both sexes and 

 all the groups of the Apache. 



(]}') The respiration rate is higher in both sexes and in all groups 

 of the Pima than in similar divisions of the Apache, but the differ- 

 ences diminish with age. 



(cO The rate of respiration is slightly greater in the females of both 

 tribes than in the males. 



{d') The pulse-respiration ratio is slightly higher among the Apache 

 children in all the divisions than among those of the Pima and in 

 both tribes it is very slightly higher in the females than in the males. 

 The ratio shows no material or regular differences accompanying 

 variations in the stature — that is, in the age of the children — and 

 throughout is lower than in the whites. 



{a") The temperature (sub lingua) differs on the whole but little 

 from that of whites. 



Q)") The temperature is slightly higher in nearly all the divisions 

 of the Pima than in the corresponding groups of the Apache. 



{c") The temperature is very slightly higher in the majority of the 

 groups in the females than in the males. "■ 



Muscular force. — ^All the tests for muscular force were made w^th 

 a Collin'' dynamometer, the same instrument being used through- 

 out the examinations. The pressure tests were made with the sub- 

 ject in a standing posture holding the hand and forearm free from the 

 body, exerting the maximum pressure on the instrument by squeez- 

 ing it, first in the right hand and then in the left. The traction force 

 was tested by the subject in a standing posture, hooking his medii 

 into the ends of the dynamometer and exerting the maximum trac- 

 tion, without raising the instrument above the chin.*^ Repeated trials 

 for both pressure and traction were made in many instances. There

 and sets of observations see tables in Appendix. 

 b The instrument is identical with that made by Mathieu, of Paris, 

 c If raised above this height, it is possible to augment the record.
