II. FILIPINO TYPES : MALECON MOKGUE. 



319 



The Igorots and the Japanese are so nearly identical in cephalic index 

 that they must be related peoples if head form is a criterion of type, and 

 at the present time it is one of the best criteria in use. The presence of 

 the Iberian and Australoid types, which have similar head forms among 

 both the Japanese and Igorots, readily accounts for the relationship. The 

 Morgue and the Student groups have almost identical cephalic indices, 

 and their heads are wider than the others. This is no doubt due to a 

 great preponderance of the Primitive, Modified Primitive, Alpine, B. B. 

 B., and Adriatic among the littoral Filipinos. Nurture could hardly 

 exert an influence on head form, but distortion by the sleeping position 

 in infancy and childhood should be considered as a factor, especially in 

 extreme brachycephaly. There are, however, broad heads with no ap- 

 parent distortion; therefore distortion will not account for all broad- 

 headedness.

The head length conforms to the cephalic index in that the long headed 

 Japanese and Igorots are mesocephalic, and the shorter headed Morgue 

 and Students are brachycephalic. The Japanese have the longest heads, 

 although they are not much longer than the Igorots. The range of 

 variation is greater for the Morgue males than for any other group as 

 indicated by the minimum and maximum head length. The shortest 

 head occurs among the male Morgue subjects, the longest among the 



Japanese.

The broadest heads are found among the Students and the narrowest 

 among the Igorots, although the Japanese and Morgue subjects are but 

 little broader than the Igorots. The narrowest head occurs among the 

 female Morgue subjects, and the broadest among the Students. The 

 female Morgue subjects have the greatest relative range of variation in
