The smaller (p, the flatter the maxillary part of nasal bridge. 
If we now turn to Table XXII we find a number of additional correlations, 
which are sufficiently interesting to make one appreciate how much more valuable 
they would have been had we had longer series and more variety of races avail- 
able. We have first correlated the mesodacryal and simotic portions, DS — SS 
and SS, of the whole subtense of the nasal bridge. In every case dealt with, male 
and female, these subtenses are negatively correlated. On the other hand the 
correlation of the mesodacryal subtense with the simotic subtense is always posi- 
tive and often substantial*. This positive correlation is therefore due to the 
appearance of SS in both variates, i.e. it is a spurious correlation. Actually when 
the maxillary part of the nasal bridge is larger, then the simotic part is smaller. 
Intraracially — that is among individuals of the same race — there is a compen- 
satory growth of the nasal bridge and those who develop large nasal bones have a 
smaller maxillary nasal development. This point seems to us of very great im- 
portance ; the tendency now-a-days is to insist on the importance of anatomical 
unities. This has largely arisen from two sources. In the first place craniology 
* For the mesodacryal subtense with the simotic subtense, all the correlations except that for the 
male Chimpanzee are positive and often substantial, the intraracial correlation amounting to + - 34 to 
+ •38. Further the interracial correlation is high indeed, being +'81 to +-87. But as we see these 
results are in part spurious.
