male leng-th ; also the variation range is much greater in the 

 male. Chervin found the average foot length in the male to be 

 238 and 56 for the range of variation ; in the female 222, with a 

 range of variation of 28. 



The seriation table shows the shortest foot was found in a 

 male, as well as the longest, also that 42.2% of the males have 

 longer feet than the longest of the female. 



In the male the foot width averages loi, the maximum 121, 

 the minimum 89, and the variation range 32. In the female the 

 average is 88, the maximum 97, the minimum y2, and the varia- 

 tion 25. This measurement was not made by the 1912 Expedi- 

 tion. It is worthy of notice that the maximum foot width (97) 

 in the female is less than the average (loi) of the male and also 

 the variation range is less in the female. 



Chervin's results show an average foot width in the male of 

 loi, with a range of 29, in the female an average of 90, and a 

 range of 12. 



The seriation table of foot measurements shows that 75-9/^ of 

 the males have a foot width between 95 and 105, while only 7.3% 

 of the females are within these limits. 



Foot Index. 



The average foot index (^^^-j — ^ — j in the male is 42.4, the 



extremes 52.5 and 34.0, and the variation range 18.5. 



In the female the average is 41.2, the extremes 45.2 and 34.9, 

 and the range of variation 10.3. The female foot is therefore 

 smaller and relatively narrow as compared with that of the male. 



Chervin gives for the Quichua male an average index of 41.77, 

 extremes of 47.84 and 36.88, and a range of 10.96. For the 

 female he finds an average of 40.39, extremes of 42.72 and 36.21, 

 and a range of 6.5. 



This index varies racially in the male from 38.4 to 44.8, the 

 latter being the index for the Colorado Indians.
