(TT I p \ 

 - — — — gives 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 y ear 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 j6 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 



( — * IO ° ) gives the ear index, which is of some racial importance. 



In the Kharga men it averages 58. p. 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.
