The mean of the two measurements of the ear( - - Wives the 
"dimension" (etendue, Topinard) or module (Schwalbe) of the 
ear, a determination useful for comparison. In the Kharga series, 
the average ear module is 5.0, the least 4.4, and the greatest 5.75 
cm. In the 20-59 vear group of Schwalbe's series the module aver- 
ages 5.12; in 13 male negroes measured by Topinard (1. c.) it was 
4.78, in 8 " Europeans " 4.86, in 8 Melanesians 5.58 and in 3 Poly- 
nesians 5.2. In the 20 American negroes measured by the writer it 
was 4.84, in the 76 Indians 5.3. The mean size of the ear in the 
Kharga natives stands evidently nearer that of the whites than that 
of the negro, particularly when the stature differences are taken into 
consideration. 
The percental relation of the breadth to .the height of the ear 
f Vr IC ~) gives the ear index, which is of some racial importance. 
In the Kharga men it averages 58.9. Topinard (1. c.) obtained for 
8 "Europeans" 54.0; 13 African negroes 61.2; 8 Melanesians 59.5 
and 3 Polynesians 60.0 ; while in Schwalbe's series the index ranges 
from 61.5 in the adults between 20 and 59 to 58.7 in those between 
70 and 79 years of age. The 20 American negroes measured by the 
writer gave the mean index of 61.6, the 76 Indians 57.2. The ear of 
the Kharga men may therefore be regarded as a relatively narrow 
one, in which respect it differs from that of the Alsatians and the 
Germans, so far as represented in the Schwalbe series and especially 
from that of the negro. 
The range of variation in the ear index in the Kharga men is 
rather large, extending over 17.4 units, or 0.148 per unit of the 
average. Its distribution is regular.
