(o) Face breadth, being the distance from one zygomatic maxillary suture 
to the other. The measurement must be taken from the lower end of these 
sutures, from the lower front rim of one cheek-bone to that of the other. Taken 
with the callipers {GB). 
(p) Zygomatic breadth, from the outermost point of one zygomatic arch to 
the like point on the other. Taken with the callipers (/). 
(q) Nasal height, measured from the nasion to the lowest edge of the 
pyriform aperture. Taken with small callipers (NH). 
(r) Nasal breadth, greatest breadth of the nasal aperture, wherever it may 
be. Taken with small callipers (NB). 
(s) Breadth of orbit (Oj), for both left (L) and right (R) eyes; the greatest 
breadth from side to side of orbit wherever found, measuring from inner margin 
to inner margin. Taken with small callipers (see p. 430, below). 
(t) Greatest height of orbit (O2), for both left (L) and right (R) eyes; 
taken as closely as possible perpendicular to 0^ by aid of small callipers. 
(u) Length of palate (Gi); measured from the point of the spina nasalis 
posterior to the inner wall of the alveolar rim between the middle incisors, with 
small callipers (see p. 429, below). 
{v) Breadth of palate {G.^ ; between the alveolar walls at the second 
molars. With small callipers. 
{w) Profile length. From the basion to the alveolar point {GL). 
(cc) Condylar width (TTi). Greatest width of mandible at condyles, from • 
outside of one condyle to outside of second. With callipers. 
{y) Angle width (TF2). Greatest width of mandible at angles; from 
outside of one angle to outside of the other. With callipers. 
{z) Greatest height of mandible (/ij) ; measured from lowest median pro- 
jection to top of process between middle incisors. With small callipers. 
{zz) Distance between foramina mentalia. With small callipers. 
From these measurements the following indices were determined : 
(a) The cephalic index (100 BjL') for greatest length. 
(/8) The cephalic index (100 BjL) for horizontal length. 
(7) The ratio of height to length (100 HjL') for greatest length. 
(8) The ratio of height to length (100 HjL) for horizontal length, 
(e) The height to breadth index (100 HjB). 
(0 The breadth to height index (100 BjH).
