portion of the nose would thus signify a broad simotic portion. But the whole 
result is, as that for the subtenses, spurious and arises from the simotic portion 
recurring in the mesodacryal chord. If we subtract the simotic chord from the 
mesodacryal then the difference (DC — SG) is negatively correlated with the simotic 
chord SC, and the correlation is fairly substantial both interracially and intraraci- 
ally. In other words, whenever a race or an individual is found for which the 
nasal bones have a big projection on the base of the nasal bridge, then the 
maxillary bones have a small projection, and vice versa. Thus individually and 
racially a principle of compensation appears at work. Now we have seen that 
intraracially <f> is negatively correlated with cf)', or a steep maxillary portion is 
associated in the individual with a flat nasal bone portion of the bridge. Thus 
intraracially it is conceivable that even if the breadth of the nasal bone and the 
breadth of tlie maxillary wall of the nose were positively correlated, the projections 
might well be of opposite signs. But we cannot use this explanation to account 
for the negative interracial correlation of the projections, for here the maxillary 
and simotic nasal angles are positively correlated. In the case of intraracial 
correlations not only are the projections ^SG and ^(DC — SG) negatively correlated 
but also the subtenses SS and (DS — SS). Thus it is not improbable that in the 
individual a small nasal bone is associated with a large maxillary wall of the 
nose — a feature we may speak of as the Orang-utan character. But this does 
not hold interracially, for the subtenses SS and (DS — SS) are positively correlated 
(Table XXII) and substantially so for both sexes. It is of some interest to con- 
sider whether interracially the nasal bone and the maxillary wall of the nose are
