The Highland and Lowland Igorots have practically the same angle, 

 while that of the women is greater. The angle decreases with age, for 

 examijle: Four boys below the age of 10 have an angle above 80°, after 

 this age it is below 80°. 



'\Vlien compared with the cephalic index prognathism becomes eWdent 

 among the brachycephalic, while the dolichocephalic are less prognathous 

 and the mesocephalic are clearly mixed. The brachycephalic resemble 

 the Negrito in their prognathism.

The exactness with which the Bontoc and Blandas, the Highland and 

 Semang, and the Lowland and ''Eeine Senoi" correspond is remarkable. 

 The similarity between the Igorots and the inhabitants of the Malay 

 Peninsula is so exact that if cephalic index is the criterion of type, the 

 conclusion must be that they are identical types of people. 



The height index of the head is given next, because it is closely 

 associated with the cephalic index.

The correlation of head height is almost reverse iu its relation to 

 the horizontal diameters (cephalic index). Could the low headed doli- 

 chocephals be eliminated from the lowland group, the index would be 

 raised higher than the highland, and the groups of Igorots would then
