The Cro-Magnon cranium stands between the Eskimo and Egyptian with a 
recession of 17-2 and an elevation of 1-5. Owing to the flatness of the skull in 
the neighbourhood of the vertex, the values of the recession can only be looked 
upon as approximations. Far more racial determinations are desirable before 
conclusions can be drawn, but undoubtedly these measures of the elevation and 
recession of the vertex suffice to difl^erentiate those races like Moriori and Eskimo 
in which a receding sagittal crest is a marked feature. 
As a last feature of the sagittal section we ma}' consider the angle between 
the nasio-lambda line and the standard horizontal. We have found no case 
of the depression of this line below the nasio-gamma line; the racial elevation is 
always about 9° to 13°. We have:

Thus we again see the Moriori and Eskimo at the top. It might be thought 
accordingly that the elevation and recession of the vertex in Moriori and Eskimo 
was due to a mere tilt of the cranium. The reply to this is that there is an actual 
physical ridge, there being actual concavity in some cases of the parietals on 
either side of the sagittal suture. 
A useful piece of work would be to add the basion, the inion, the opisthion 
and the suborbital and auxicular points to Crewdson Benington's contours — 
they are given on his individual tracings; so that racial comparisons might be 
made of the lower portion of the cranium from his sagittal type contours. 
7. On Mean Values found from Type Contours. We now turn to the second 
problem relating to the type contours : How far can we be certain of mean values 
obtained from them? We may note several general points before we proceed to
