prolonged gamma-nasion line being T and the point of contact of the tangent 
being G, the ordinate GT and the abscissa TN represented by the letters Gy and 
Gx respectively were measured, they are practically the coordinates of the glabella. 
To complete the drawing of the frontal part of the sagittal contour, an extra 
ordinate was measured at \ the distance from 0 to 1 ; this line is spoken of as the 
N\ line. Perpendiculars were also dropped from the opisthion, auricular point 
and suborbital point to Ny. Also a perpendicular from the most projecting point 
of the contour just above the inion was drawn to Ny. These points will now 
be found amply suflEicient to reproduce the individual contour as closely as it could 
be redrawn by the Klaatsch.

The type contours are constructed as before. See Figs. I and II. 
{d) General remarhs on Contours. Illustrations of the type contour of the 
Moriori are shown in Figs. I to VI. For the sagittal contour: 
N — Nasion, Gl. — Glabellar point, B = basion, ^ = Bregma, V = vertex, 
A = Lambda, y = Gamma, Z = Inion, OjJ. = Opisthion, ^ot. = Auricular point, 
Bas. = Basion, Alv. = Alveolar point, Suborb. = Infra-orbital point. Suborb. to 
Aur. if joined by a line gives the standard horizontal plane. Ny is the horizontal 
plane through the nasion. The angles N, B and A are the nasal, basilar and 
alveolar angles of N BAlv. the fundamental triangle. P = the profile angle measured 
from the Frankfurt horizontal, </> = the angle between the glabella-inion and 
glabella-bregma lines, ^' = the angle between the nasion-inion and nasion-bregma 
lines. There are three interesting subtenses, S, X and y. y is the maximum subtense 
or height of the calvaria measured from the glabella-inion line, ,s- is the corresponding 
bregma subtense and X is the bregma subtense to nasio-lambda line. 
The most marked characteristics of the Moriori skull are the depressed 
and retreating forehead, the bulging glabella, and the high sagittal crest. On
