\ chin hair line height / 
The total physiognomic facial index averages in the Kharga men 
74.7, showing a tendency to leptoprosopy, which will be even more 
clearly apparent in the anatomical index. The range of variation is 
not excessive, extending over 16.3 points, or 0.109 per point of 
the average. The distribution of the index presents two distinct 
modes (fig. 10).

The Anatomical Facial Index T . r-^- 
\diameter bizygomatic maximum/ 
The anatomic, or facial index proper, averages 86.3, which ap- 
proaches the boundary between meso- and leptoprosopy. 1 Its range 
of variation is unexpectedly larger than that of the physiognomic 
index, extending over 30.7 points, or 0.178 per unit of average, 
but the distribution of the index shows that 93.3 per cent of the 
cases are concentrated between the boundaries of 78 and 94. Only 
two individuals occur with chamseprosopy ; in 119 the face is meso- 
prosopic and in 29 leptoprosopic (fig. 10). 
1 Chamaeprosopic, below 74.9; mesoprosopic, 75-89.9; leptoprosopic 90 and 
above.
