Burmans and Hindus. We next compare our Burmans with the Hindu material 
that has been gathered together. Here we find more characters exhibiting differ- 
ences which cannot be other than racial. The major measurements reveal at once 
the comparative smallness of the Hindu skull, which, though not losing anything 
in length* (L), shows a markedly smaller maximum breadth (B) especially for 
males, and less height (H), and, as we should expect, smaller capacity (C). The 
height above the auricular points (OH), as also the arc (Q') connecting these two 
in the vertical plane, are correspondingly reduced; it may be noted, however, that 
the breadth of forehead {B'), unlike the maximum breadth, remains practically 
the same. These figures bring out the fact that the cranial box of the Hindu differs 
from that of the Burman not only in size but in shape. Thus the Hindu skull is 
niesocepbalic (B/L) against the brachycephaly of the Burman; its relative height 
and length {HjL) bring it to the border-line between hypsicephaly and orthocephaly, 
and its mean maximum breadth [B) is exactly equal to its mean height {H) while 
the Burman breadth exceeds the height. 
When we examine the features of the Hindu face, we find again a considerable 
diminution in size. It is less high [G'H) than that of the Burman, less broad, both 
as regards zygomatic (J) and maxillary [GB) breadth; the nose is both shorter 
[NH] and narrower (NB); so also are the orbits (O^' and O^). Its palate is rather 
narrower, but is approximately as long as that of the Burman; the difference, 
however, is not so great as to put them in different palate categories. 
The finer proportions of the Hindu nose classify it as mesorhine, one class higher 
than that of the Burman nose; and the orbit is less round. 
AU these racial characteristics are exhibited by both male and female, in their 
mean values. 
As before, we find some racial differences which can be considered significant 
in the males alone: a smaller horizontal circumference (U) in the Hindu, and a 
* It will be noted that this inference is based upon the data for (L) from Hindu skulls alone. The 
bulk of the data for this character for Hindu females was obtained from the catalogue of Barnard Davis' 
collection, and a comparison of this mean measurement both with the corresponding male value, and 
with that of the females in our Hindu group at the Biometric Laboratory, suggests some doubt as to 
the accuracy of these particular figures.

Our own series is too small for any real stress to be laid upon the means obtained from them alone; 
but that the mean length of the male and female head should be practically the same in any one race, 
as the figures from the Bainard Davis' catalogue would indicate, is a condition paralleled by the 
constants of no other race that has been studied: the average reduction for the female mean is about 
one twenty -fourth of the male value (mean of 20 races). , .
