It should be borne in mind that the foregoing intertribal differences 

 in the pulse-respiration ratio are due not to differences in the pulse 

 rate, which are small, but to the relatively slower respiration in the 

 Apache. It is difficult to fathom the cause of this characteristic 

 without much further study. The condition of life of the two series 

 of subjects on whom tests were made, particularly the school children, 

 differed but little. 



Temperature in relation to stature: The tests for temperature were 

 made with good clinical thermometers and invariably under the tongue. 

 To insure greater accuracy two thermometers were used simultane- 

 ously in most of the cases, one mider the right and the other under 

 the left side of the tongue. The instruments were left in the child's 

 closed mouth for at least six minutes. Nothing was done on the part 

 of the children to disturb these tests. The following table and curves 

 (pi. XIV) show the results:
