The Indians of Cuzco 27 



The dorsum nasi, as seen from the above table, is straight in 

 nearly equal proportion to the two sexes, is convex nearly twice as 

 often in the male, and is concave to a much greater extent in the 

 female. The writer found somewhat different results in the 

 previous study ; they were as follows in the male : the dorsum 

 was straight in 29.7%, concave in 11.7%, convex in 15.2%, and 

 sinuous in 43.4%. The nearly straight or slightly convex dorsum 

 nasi is the predominant type in the Quichua male, while the nose 

 of the female is more frequently concave. 



The nasal depression was recorded as medium, submedium, 

 shallow, deep, wide, high, and narrow. In the males 68.2% 

 were of the medium type, 4.7% submedium, 8.2% shallow, 2.4% 

 deep, S-9% wide, 9.4% high, and 1.2% narrow. 



In the females 6i.S% were medium, 5.9% submedium, 19.1% 

 shallow, 1.5%! deep, and 11.7% wide. This agrees essentially 

 with part of the observations of the 1912 Expedition, which 

 found the nasal depression in the male medium in 64.6% but 

 differs chiefly in the smaller per cent of those rated as high. 



In the male the base of the nose is horizontal in 16.5%, inclined 

 slightly upward in 45.9^, slightly downward in 37.6%. 



In the female the base is horizontal in 11.8%, inclined slightly 

 upward in 69.1%, and slightly downward in 19.1%. The nose 

 of the female is more frequently concave with base inclined 

 upward than that of the male. 



The character of the root of the nose, whether projecting or 

 depressed, depends largely upon the forward growth of the 

 mesethmoid. This growth occurs chiefly after childhood and 

 the greater frequency and more marked nasal depression of the 

 female represents the more frequent persistence of the infantile 

 type of nose in the female. 



The height of the nose was measured by fine-pointed sliding 

 compasses from the nasion to the subnasal point, and the breadth 

 ■was the greatest from one ala to the opposite at their lower 

 borders. 



The nasal index expresses the relation of the breadth to the 

 height rather than the length of the nose. 



The height of the nose in the male averaged 57 millimeters, 

 the greatest 70, the least 48, with a variation range of 22. The 

 width averaged 40, with extremes of 47 and 34, and a variation 

 range of 13. In the female the height averages 53 millimeters, 

 the greatest 64 and the least 41, with a variation range of 23.
