The following table presents the average measurements of the thirty-two men: Average measurements of Bontoc men Measurements Stature 160.287 Spread of arms 165.684 Head length 19.212 Head breadth 15.203 Nasal length 5.25625 Nasal breadth 4.1625 From these measurements it appears that the composite man the average of the combined measurements of thirty-two men is mesaticephalic.

The Prague Museum possesses two crania found at Bilin in Bohemia; one, of a pronounced dolichocephalic type, has near the middle of the right parietal an opening measuring one and a half by two and a third inches; the cicatrization is complete, and trepanation was evidently performed long before death. The other is mesaticephalic, and bears a round opening about one and a half inches in diameter.

The breadth of the head is about the same as the Ilocano; but the length is much greater, and there is, in consequence, a considerable difference in the cephalic index. Reference to our tables will show the Ilocano and both Tinguian divisions to be brachycephalic, while the Igorot is mesaticephalic.

The following table presents the average measurements of twenty-nine women: These measurements show that the composite woman the average of the measurements of twenty-nine women is mesaticephalic. The extremes of cephalic index are 87.64 and 64.89; both are measurements of women about 35 years of age.

Individuals of each type are found in all the groups considered, but taken in the average, it is found that the Ilocano and Valley Tinguian fall into the first or round-headed class, the Bontoc Igorot are mesaticephalic, while between them are the mountain Tinguian and Apayao.

Among the thirty-two men, nine are brachycephalic that is, their cephalic index is greater than 80; twenty of the thirty-two are mesaticephalic, with cephalic index between 75 and 80; and only three are dolichocephalic that is, the cephalic index is below 75. The nasal indexes of the thirty-two men show that the Bontoc man has the "medium" or mesorhine nose.

On one of the three crania there were two wounds near each other, but they were quite separate, and were evidently not treated at the same time. Mesaticephalic skull, with wound which has been trepanned. At the southeastern extremity was picked up a badly baked hand-made earthenware vase with four handles.

Of the twenty-nine women twelve are brachycephalic; twelve are mesaticephalic; and five are dolichocephalic. The Bontoc woman has a "medium," or mesorhine, nose, as is shown by the above figures.
