III. FILIPINO TYPES : RACIAL ANATOMY IN TAYTAY. 401 



Some types, however, ha\e a greater number of straight upper lids, 

 whereas others have the fold in greater number. Tluis the Australoid and 

 the Iberian have a greater number of individuals with straight lids, 

 whereas the Alpine, Modified Primitive, and Cro-Magnon have a greater 

 num])er with Mongolian lids, and the Blend has almost an equal number 

 of each. May it be inferred from this that the Australoid and Iberian are 

 other than true Asiatic types, whereas the Cro-Magnon, Alpine, and 

 Modified Primitive are true Asiatics, also that each type is represented 

 among the Chinese? ISTone of the Primitive or B. B. B. were examined 

 for lid formation. 



HEAD OUTLINES. 



Composite outlines of the three groups, brachycephalic, 74 indi\-iduals, 

 mesocephalic, 69 individuals, and dolichocephalic, 22 individuals, are 

 made in the same manner that similar outlines were made for the Igorots, 

 negroes and white students described in former studies (3). 



There are two dolichocephalic outlines because so few individuals did 

 not produce one composite, there being enough large outlines to make 

 an additional composite outside of the one where the greatest number 

 produced the small outline. 



A glance at the outlines (figs. 5, 6 and 7) will show the dorsal flatten- 

 ing marked in the brachycephalic, whicli at once differentiates the Tay- 

 tayans from tlie Igorots, negroes or white students. This flattening in 

 the brachycephalic (fig. 5) is accompanied by projection in the parietal 

 region, prominence in the region of the bregma and bulging in the 

 temporal region, which suggests artificial flattening by pressure from 

 behind. Many of the heads were flattened toward one side rather than 

 exactly in the middle, and when this condition existed the opposite side 

 bulged in the parieto-teniporal region .more than the side on which the 

 dorsal flattening was most marked. (See Plate XA'III.) 



In several children this was more decided than in adults. One of 

 these is given in fig. 8 where the two outlines are shown as taken with 

 the cephalograph over the middle of the right and of the left eye 

 respectively and parallel to the median line. Another is shown in fig. 9, 

 with the median sagittal outline and one parallel to it 3 centimeters to the 

 left. The first of these is of a boy, aged 4, whose father brought the 

 child to me for consultation. The boy had slept invariably with his 

 liead on a hard 1)oard covered with only a thin matting, the petcite, with 

 the head tiirned to the left at an angle of 45°, and I attributed the trouble 

 to this cause. The head of the second boy, aged 10, was not so distorted 

 but without doubt the condition was due to the same cause. These two 

 cases illustrate a condition that is found frequently among the children 

 and I believe it is nothing more nor less than the peiritp habit that 

 produces it.
