5 and 80,
_mesaticephalic;_ and those over 80 _brachycephalic._ The beads of the
Aeta are essentially _brachycephalic._ Owing to the lack of proper
calipers during the greater part of my stay among them, I was able
to measure only 19 individuals, but of those all but 5 were in the
_brachycephalic_ group, one instance being noted where the index was
as great as 92; the lowest was 78. The average of the males was 82
and of the females 86.

Considerable importance in anthropometry is attached to the study
of the nose. The typical Aeta nose may be described as broad,
flat, bridgeless, with prominent arched alae almost as high as the
central cartilage of the nose and with the nostrils invariably
visible from the front. The nasal index obtained by dividing the
nasal breadth by the height from the root of the nose to the septum
and multiplying the quotient by 100 serves to indicate the group to
which the individual belongs. Thus it will be seen that races with a
nasal index of more than 100 have a nose wider than it is long. This
is a marked characteristic of the Aeta. Of the 76 Aeta I measured,
25 were _ultraplatyrhinian_--that is, had a nasal index greater than
109. One individual, a female, showed the surprising index of 140.7,
the greatest so far recorded to my knowledge. The greatest nasal
index among the males was 130.7. Only one example of a _mesorhine_
nose was noted, also of a female, and but 7 _platyrhine._ The most
of them belonged in the _hyperplatyrhine_ group. The following table
will show the proper classification of the individuals measured by me:

Group Sex and number
Males Females

Mesorhine (69.5-81.4) -- 1
Platyrhine (81.5-87.8) 3 4
Hyperplatyrhine (87.9-108.8) 27 16
Ultraplatyrhine (109 and over) 51 10

The shape of the eye varies from the round negroid of the pure bloods
to the elongated mongoloid in the case of mixed types. The color of
the eyes is a very dark brown or black. The lips are medium thick, far
less thick than the lips of the African negro, and are not protruding.

The hair of the Aeta is uniformly kinky in the case of the pure
types. Individuals were noted with other negroid features but with
curly hair, showing a
