 the mesocephalic are intermediate in size. (Fig- 3.) The composite

curves of the three groups are similar. The forehead of the brachyce- 

 phalic protrudes slightly and the occipito-parietal region is somewhat 

 flattened. 



When the composite dolichocephalic head outline of the Igorots is compared 

 with a similar outline from an equal number of negroes I measured in Baltimore 

 at the Johns Hopkins Hospital Dispensary in 1906, the data being as yet un- 

 published, and an equal number of white students of the University of Michigan 1 

 measured at Ann Arbor in 1905 to 1907(4), some striking differences may be 

 seen. (Fig. 4.) The head of the' Igorot is the tallest and shortest of the three,

whereas that of the white student is the lowest and longest. The forehead of 

 the negro is low and receding, while that of the Igorot and white student are 

 high and prominent. The head region immediately above the somasthetie area
