brown being dominant to brown, brown to gray, gray to blue, tire later 

 being the piire recessive. 



Certain types by reason of their numl)ers, their derivation and their 

 general distribution may be considered typically American. Such are 

 the Northern, Iberian, Saxon, Celt and Blends Nos. 1, 2, and 5. The 

 Alpine, Vistulian, Littoral, Adriatic and Blends Nos. 3 and 4 are largely 

 of recent foreign extraction. The trend of the American type is in the 

 direction of increasing height, blended coloring and mesocephaly. 



SUMMARY. 



Physical measurements of 983 boys and 116 girls are presented, with 

 eye color, hair color, and head outlines; and various indices of the head 

 are comp)uted, the brain weight is calculated, and the class standing is 

 given. Prom these data types are selected representing existing homo- 

 genous entities. 



Eipley's three European races predominate, Deniker's European races 

 are found somewhat modified, and in addition to these tyj)es, five blended 

 types are designated. 



A tentative scheme for type heredity is formulated to explain the 

 relation of the types found to the types known to have existed in the 

 past, and to indicate existing tendencies and predict future developments 

 of types in America. 



CONCLUSIONS. 



Collective evidence favors the conclusion that the j)rehistoric types 

 of men in Europe have persisted to the present time, and are found in 

 America somewhat modified; other types are found representing later 

 intrusions into Europe; a blending of these types has transfonaed them 

 and created new ones; and the apparent ultimate result will be a com- 

 plete fusion of all the types. 



Feminine types corresponding to the masculine are nearer in form to 

 the primitive, not having Ix'come so differentiated. 



All hypotheses and conclusions are tentative, and await other work 

 now pending for confirmation. 



My thanks are due to Dr. McMurrich for his great kindness to me 

 during the time I was engaged in making the physical measurements, 

 especially for taking my classes, and only through his generous assistance 

 was I enabled to complete the work.
