viduals in the series (Pima and Tarahumare) showed the highest pulse 

 rate. 



Respiration: The number of respirations per minute in healthy 

 whites, in a sitting position, is from 15 to 20. The averages in the 

 Indian males as well as females ranged from 16 to 19, much as in 

 whites; the extremes observed in males were from 12 to 22 and in 

 the females from 13 to 23.'^ 



There seemed to be no regular difference between the tallest and the 

 shortest tribes, but in the same tribe the frequency of breatliing 

 was found to be slightly less in the tallest than in the shortest indi- 

 viduals. 



As to the sexes, in four of the five tribes with larger groups of 

 individuals the frequency of respiration was slightly greater in the 

 females, and in all probability this is generally the normal condition 

 in the Indians. 



As with pulse, there were no regular variations of respiration with 

 different times of day, but this may have been in both instances due 

 to the fact that the extremes were not sufficient or identical. 



In the young adult Indians, as contrasted with the aged, the 

 rate of respiration is quite regularly a little higher. 



On account of the slower pulse in the Indian the pulse-respiration 

 ratio, with about etjual respiration frequency, is generally lower than 

 in whites (that is, less than 4 to 1). 



Temperature: The temperature under the tongue in healthy adult 

 whites ranges from 98.8° to 99^ F. In the Indians it averages appre- 

 ciably less, ranging in malps from 98.1° to 98.8° F. (extremes 96.2° to 

 99.9° F.) and in the females from 98.5° to 99.4° F. (extremes 97.7° to 

 99.9° F.). 



There is apparent a closer correspondence between temperature and 

 pulse than between pulse and respiration. 



No regular difference was found between the tallest and the shortest 

 tribes; but in the same tribe the temperature of the tallest indi- 

 viduals averages quite generally slightly higher than that of the 

 shortest persons. 



In females it is a little higher than in the males. 



In the morning the temperature (in the males) is mostly slightly 

 lower than in the afternoon. 



Finally, in the youngest adults in the tribe the temperature w^as 

 found to average a little higher than in the oldest ones. 



The most noteworthy results of the above tests are the generally 

 lower pulse and temperature in the Indians as compared with whites. 



a Observations secured in the National Museum on healthy male full-blood Indians visiting that 

 institution show the following averages- 2 Creeks, 17.5; 2 Menominee, 17; 1 Mohican, 20; 2 Muscogee 

 Creeks, 18; 3 Navaho, 18; 4 Osage, 17.5; 2 Pawnee, 20; 1 Pueblo (Isleta), 20; 1 Seneca, 15; 1 Ute, 19; 

 1 Yakima, 21; 7 Yankton Sioux, 20.
