The Indians of Cuzco 19 



In the case of the Quichua female the average index is 55.6, 

 the extremes 7Q.3 and 48.6, with a variation range of 21.7. It 

 is thus seen that the average index is distinctly higher in the 

 female and the variation range less. Chervin gives this index 

 as 53-7 (/cases). 



A review of the seriation tables shows that 67.1% of the males 

 have an index between 51.9 and 54.9, while in the case of the 

 females only 48.4% are within these limits. 



Hand Measurements. 



The left hand was measured in 85 males and 68 females. The 

 length of the hand is the distance, when in line with the fore- 

 arm and the fingers extended, from the mid point of a line 

 connecting the proximal borders of the thenar and hypothenar 

 eminences to the distal end of the longest digit, which in nearly 

 all instances is the third. 



The breadth of the hand was measured from the point of 

 intersection of the thumb and a line extended from the radial 

 border of the index finger to the mid point on the ulnar side of 

 the hand between the flexion groove of the little finger and the 

 line tangent to the proximal ends of the thenar and hypothenar 

 eminences. 



In the Expedition of 191 2 the hand length was measured from 

 the interstyloid line to the end of the middle finger. It is 

 admittedly difficult to quickly and accurately determine the inter- 

 styloid line, but the measurement so obtained corresponds more 

 nearly with the hand length as determined on the skeleton. In 

 other words, the hand length as determined on the palmar surface 

 from the thenar-hypothenar tangential line does not include the 

 upper part of the carpus. The writer would judge from a few 

 observations on this point that the hand is about one centimeter 

 longer as determined by using the interstyloid line than by using 

 the thenar-hypothenar tangential line. He is inclined to the 

 belief that inasmuch as the dorsal edge of the distal extremity of 

 the radius can be felt, that it should be used rather than the inter- 

 styloid or thenar-hypothenar line. This would increase the length 

 of the hand probably by about two millimeters as compared with 

 the interstyloid line length. Perhaps, however, one objection to 

 this method of measuring the hand length is the fact that the 

 length of the forearm is measured to the styloid process of the
