(nasion-hair line) measurement, among 124 Kharga men free from calvitia. 
Chin-Nasion Height 
The distance from the lowest point of the chin in median line to 
a point corresponding to the middle of the fronto-nasal articulation, 1 
gives the height of the facial parts proper, speaking anatomically. 
Due to this fact the measurement is more suitable for the study 
of the relations that exist between the development of the face and 
that of the vault of the skull than the total or physiognomic facial 
height, which includes the forehead and is affected by the variation 
of the latter, representing to an important extent external conditions 
of a portion of the vault. 
The dimension (as also the total facial height) increases to some 
extent with age ; but in old people it is frequently found to be more 
or less reduced, due to the wear or loss of the teeth and absorp- 
tion of the alveolar processes. In the Kharga series no individual 
presented such conditions in a marked degree and no decided effects 
of age on the measurement, as will be seen later on, are perceptible. 
1 The point on the skin corresponding to nasion on the skull can in many 
cases be determined accurately by feeling, in others it must be estimated on 
the basis of the knowledge regarding the usual situation of the point in th$ 
cranium. It is generally somewhat above the middle of the intercanthic line.
