Similarly we have for the part of the "bridge" from "haunch" to "haunch," 
i.e. the nasal bones, or part between the strokes marking the naso-maxillary 
sutures, the following characterisation :

Fur classificatory purposes it may he useful to divide (j> into three classes: 
when (f> is under 46°, the group shall be called platygephyreal, when cj> lies 
between 46° and 51°, the group is mesogephyreal, and when is over 51°, the 
equality of <p and </>', marks the "triangularity" of the bridge, or the unbroken character of the nasal 
wall.

Only the Gorillas have a re-entrant racial rrjaxilli-simotic angle, although such angles occur in individual 
cases of other races. Of the races considered the English appear to have most nearly an unbroken 
nasal wall. The racial order is not clearly marked as Negroes and Asiatics are much intermixed.
