The Indians of Cuzco n 



obtained by the previous expedition. Omitting those women 

 completely sterile, the average number of children is raised to 

 3.0; 26.5 /f of the marriages were childless, as compared with 

 the former expedition's result of 27%, and twelve women had 

 only one child. Girls were in the ascendancy, there being 82 girls 

 to 61 boys, and in 9 the sex was not stated. This is in the pro- 

 portion of 100 girls to 74.4 boys, in contrast to the proportion 

 of births in the white races of 100 girls to 106 boys. Chervin 

 states that the Quichua have 100 girls to 67 boys. It is of course 

 recognized that these statistics are very imperfect and that it is 

 not proper to contrast the proportion of sexes at birth in one race 

 with the proportions living at a later period in another. 



Skix and Appendages. 



The color of the skin in the male was found to be medium 

 brown in 67%, dark brown in 2.4'Y, and light brown in 30.6%. 

 In the females the proportions are medium brown 63.3%, dark 

 brown 2.9%, light brown 33.8//. a slightly larger proportion of 

 the females having a light brown skin. There were ten cases of 

 freckles observed, 7 females and 3 males ; 20 males and 11 females 

 were pockmarked. No naevi or tattoo marks were noticed. 



In the males the scalp hair was straight in all cases and black 

 in all except one, in which it was brown, probably a mixed white. 

 In the females the hair was black in all instances and straight 

 in all but one, in which the hair was slightly wavy. In the males 

 the hair was considerably gray in four instances and slightly 

 gray in six. The scalp hair was only slightly thin in twelve 

 cases, no marked example of calvities was recorded. In the 

 females the scalp hair was slightly gray in six cases and thin in 

 two instances. Grayness does not seem to appear earlier or to 

 be more extensive in the females than males. No mention was 

 niade as to whether the hair was fine or coarse. 



So far as these results go the Quichua does not seem to entirely 

 agree with the Aymara, who. according to Forbes, never show 

 calvities or grayness if of pure blood. They, however, nearly 

 accord with those of the Yale Peruvian Expedition of 1912, 

 where only one case of slight calvities was found, in a man of 

 80 years, and a few gray hairs in three men, one of 45, another 

 of 60, and a third of 80 years. One female, No. 17, had white 

 evelashes.
