terms of the parietal, the latter always being 100. A high in- 

 dex denotes a large occipital region, a low index the reverse. 



The occipito-parietal index in the German and American chil- 

 dren from 5 to 10 years of age is 



Hyper 80.9 Hypo 79.9 



and from 11 to 16 years of age is 



Hyper 82.2 Hypo 79.4 



The occipito-parietal index in the Filipino boys is 



5 to 10 years Hyper 88.4(1) Hypo 78.3 



11 to 16 years Hyper 81.9 Hypo 76.7 



17 to 30 years Hyper 83.4 Hypo 79.9 



The index of the Filipinos is less than that of the Germans and 

 Americans at the same age, and the index of the hypo- in the Fili- 

 pino from 17 to 30 years of age has reached that of the Germans 

 and Americans at the age of 5 to 10 years, but the index of the 

 hyper- among the Filipinos at 17 to 30 years of age has passed 

 that of the Germans and Americans at the age of 11 to 16. The 

 index increases with age except that the hypo-s among the Ger- 

 mans and Americans do not change. 



The hypo- has a relatively smaller occipital region in the Fili- 

 pino than in the German, and a relatively larger occipital region 

 in the American than in the German. The same is not true for 

 the hyper-, for in them the occipital region is about the same 

 for the American and Filipino, but relatively smaller for the 

 German. 



The sexual differences indicate that the male has a relatively 

 larger occipital region than the female, and the female a relatively 

 larger parietal region than the male although the difference is not 

 great. 



No other differences will be presented here, although differences 

 in stature, weight, nose form, ear form, facial angle, cranio-facial 

 index, etc., will be given in subsequent publications, but enough 

 has been done to establish the hyper-onto-morph and the hypo- 

 onto-morph as entities and to indicate their identity.
