" Point lacrymal " is the point at which the hinder edge of the lacrymal groove 
meets the lacrymo-frontal suture. 
On. Greatest height of oi'bit, for both (X) and (R) eyes, taken as closely as 
possible perpendicular to Oj. 
Oi. Length of palate, measured from the point of the Spina nasalis posterior 
to the inner wall of the alveolar rim between the middle incisors. 
Qi- Breadth of palate between the alveolar walls at the second molars. 
GL. Profile length from the basion to the alveolar point. 
TTj. Condylar width. Greatest width of mandibles at condyles, from the 
outside of one condyle to the outside of tlie other. 
TFo- Angle width. Greatest width of mandibles at angles, from the outside 
of one angle to the outside of the other. 
hi. Greatest height of mandible, measured from the lowest median projection 
to the top of process between middle incisors. 
f. Distance between foramina mentalia. 
C. Indices. 
B/L'. Cephalic index for horizontal length. 
B/L. Cephalic index for greatest length measured from the glabella. 
H' jL'. The ratio of height to length , for horizontal length and the whole height. 
H/L. The ratio of height to length, for the greatest length measured from the 
glabella and for the auxiliary height. 
G'H/GB. The upper face height to face breadth index. 
NBjNH. The nasal breadth to nasal height index. 
O2/O1 {R), O2/O1 (L). The orbital height to orbital breadth index for both 
right and left eyes. 
Go/Gi. The palate breadth to palate length index. 
P. The profile angle found with Ranke's Goniometer. 
The description of the facial measurements, and of the indices calculated, is 
taken from Miss Fawcett's paper on the Naqada Crania (Biometrika, Vol. I.), and 
the lettering used in the tables of that memoir to denote these various measure- 
ments and indices has been retained. But it will be noticed that certain of the 
measurements have been omitted, and othei's slightly modified. Thus owing to the 
imperfect state of the teeth, in many cases, the face height was not measured. 
Also the orbital breadths have been measured from a different point on the inner 
side as it was found more convenient to do them in this way. 
Owing to the few cases in which these determinations could have been made, it 
was not considered worth while to calculate the angles A Z , N Z , B Z , O^, 6.^. 
The measurement of the capacity was not attempted owing to the fragmentary 
nature of the majority of the skulls*. 
* The following six were found fit for the measurement of the capacity which is given in cm.^: 
24, 1606. 26, 1496. 38, 1592. 83, 1667, 173, 1437. 180, 1502.
