These results can not be directly compared with those of the 

 previous expedition because dynamometers of different makes 

 were used, but the comparison with the grip strength of twenty 

 white male adults of sedentary occupation with an average in the 

 right hand of 45 and in the left of 39 shows that the forearm 

 muscles are poorly developed in the Quichua. This agrees with 

 the former results. The average grip for the right hand as found 

 by Hrdlicka (7) in the male N. A. Indian varied from an 

 average of about 41.8 to 47.. and for the left hand. 38 to nearly 

 41 for different ages, being greatest in the third decade. 



In the case of the females Hrdlicka found an average varying 

 from 24.9 to 27.8 in the right hand and from 22.9 to 25.8 in the 

 left hand in the different tribes. No tests for power of traction 

 or the strength of other groups of muscles were made. Strength 

 tests for the muscles of the legs would probably show the 

 Quichua to better advantage as the development of the forearm 

 and leg muscles are markedly different. 



Pulse, Temperature and Respiration. 



There are only six observations on the sublingual temperature, 

 all on males, showing a variation from 98.4 to 98.7, with an 

 average of 98.5°. 



The pulse was counted in 85 males and 64 fei^ales, in all of 

 whom the health seemed good. In the males the lowest pulse 

 rate was 54 and the highest 102, with an average of 74. In the 

 females the average rate was 78, the lowest 60, and the highest 92. 



The rate of respiration was covuited in 80 males and in 55 

 females. The average rate in the males was 17.2, the lowest 14, 

 and the highest 21. In the females the average rate was 17.9, 

 the lowest 14, and the highest 21. The breathing in the female 

 was more diaphragmatic and abdominal than costal. 



Number of Children. 

 The number of children in a family varied up to eight, the 

 average being 2.2, which is nearly the same result (2.8) as
