and a range of 8.1. In the female the average is 14.7, the 

 extremes 17.5 and 13.6, and the variation range 3.9. This is 

 quite similar to the results of the J912 Expedition of 15.1 for 

 the average index in the male, with extremes of 16.3 and 14.1, 

 and a variation of 2.2. Chervin's. results for the male are similar 

 so far as the average is concerned (14.86), but the maximum 

 (16.53) is somewhat less, while the minimum is greater than our 

 results. Chervin's average for the female is 14.43. The stature- 

 foot length index in the Qviichua is about the same as in the 

 Colorado and Brazilian Indians and the Chinese (Martin). The 

 relative foot length, however, seems to have little value as a racial 

 character. 



Leg Circumference. 



The maximum leg circumference was measured only in the 



left leg in 58 males and 47 females. This dimension averages 



in the male 341, with extremes of 390 and 268, and a range 



variation of 122. In the female the average is 331, the extremes 



are 413 and 226, with a variation range of 187. This agrees 



fairly well with the results of the 1912 Expedition, viz., an 



average for the male of 341, a maximum of 405, a minimum of 



287, and the range of variation of 118. The least supramalleolar 



circumference was not measured but the average in the male 



Quichua was found by the former expedition to be 214, with a 



variation range of 55. Also the average leg circumference index

the index is low in contrast with most races, which means that 

 the triceps surae muscle is large in the Quichua. This harmo- 

 nizes with the common observation and is in part due probably 

 to the mountainous country inhabited by these people. In six 

 instances the maximum leg circumference of the female was 

 smaller than in any male and in eight cases larger.
