figures indicate that both the facial and the alveolar protrusion in the 
Munsee was exceedingly moderate for a group of Indians, although in 
a measure the height of the indexes is due to the shortness of the face. 
PALATE 
It was possible to obtain satisfactory measurements of the palate 
(or, more strictly speaking, the upper alveolar arch) in 13 instances, 
which, in view of the usually frequent defects of the arch, is a good 
proportion of the cases. The measurements and indexes follow 
Turner’s method, which is quite satisfactory... The greatest length 
recorded by Turner in 20 European male and 8 European female 
skulls was 6 cm., the smallest 4.7 cm.; the greatest breadth 6.9 cm., 
the smallest 5.6 cm. The same measurements among the Munsee 
range, if we take both sexes together, from 5.1 cm. to 6 cm. for length 
and 5.9 cm. to 7.2 cm. for breadth, showing both dimensions, though 
more especially the breadth, to be slightly superior in these Indians 
to what they are in whites. The palatal or ‘“‘uranic”’ index averaged, 
in Turner’s whites, 116.2 in the males and 115.6 in the females; in the 
Munsee the averages are 120.7 for the former and 120.5 for the latter 
sex, showing the palate in these Indians to be more “‘ brachy-uranie, ”’ 
or relatively broader. The sexual differences in both Turner’s and 
the present series are so small as to be practically negligible. In the 
different groups of Arkansas and Louisiana crania, reported in 1909 by 
the writer, the average palatal index ranged from 116 to 122 in the 
males and from 115 to 122 in the females—conditions very similar to 
those shown in the present observations. 
It may here be pointed out that the whole subject of the dimensions 
of the palate or aveolar arch in the different races, and especially in 
the different types of skull, needs investigation. As it is, the variety 
in the dimensions and shape of these structures, and especially their 
correlation with the rest of the face and skull, are only imperfectly 
understood.
