Menstruation commences earlier in the Indian than in New England 

 white girls, and retardation is less frequent. 



Tribal differences exist. 



In the males the beard begins to appear on the upper lip and soon 

 afterward on the chin, from the fifteenth to the sixteenth year; on the 

 sides of the face much later. It is more scanty than in the whites, 

 especially on the sides of the face. 



Children and adolescents of the other Southwestern tribes, so far 

 as examined, correspond in all essentials, except in the absolute 

 measurements of the body, with the Pima and Apache. 



Physic^logical Observations on Adults 



The observations that it was possible to secure on adults may be 

 divided into those obtained by the aid of instruments and those 

 gathered in other ways. The former, which receive precedence in the 

 text, included many measurements that will be more properly treated 

 of in other publications. All the data relate only to normal, fidl-blood 

 individuals, others having been excluded. 



stature 



The growth of the body is a definite function of the organism and 

 adult stature is its culmination The subject of growth will here be 

 dealt with fi"om this viewpoint only. 



The following table gives the results of the writer's measurements 

 of normal and healthy adults between about 20 and 60 years of age 

 in 38 tribally or geographically distinct groups. All the heights were 

 taken with the sul)jects barefooted and bareheaded, by means of 

 a square and Broca's graduated plane, suspended 1 meter above a 

 solid, level surface. The numbers of subjects, though too small 

 in some instances, may be considered on the whole as fairly suffi- 

 cient ; and the results of measurements agree in every case with the 

 more extensive visual observations.
