as* 73.7 mm. at birth, and 58.7 at 70 j^ears of age; and I found it 

 to be 68.1 in the 22 white fetuses and 55.0 at 60 to 69 years of 

 age in the 'old white' American m^ales, and 69.1 in the 44 negro 

 fetuses and 60.3 at 50 to 59 years in the American negro males. 



Stature arid ear dimensions, adults: It is seen that the length 

 and breadth of the ear increase with increase of stature, the 

 length relatively more than the breadth, therefore the physiog- 

 nomic index of the ear decreases with increase of stature, except 

 among the negroes where the reverse is true. The breadth of 

 the ear increases more than the length with increase of stature 

 in the negro males, therefore the physiognomic index increases 

 with increase of stature. Thus the negro racial characteristics 

 of the ear are emphasized with increase in stature, purity of 

 ear tj^De goes with tallness in the negro males. 



If we take the same stature in each group, for instance the 

 stature of 160 to 169 cm., we find that the ear length, breadth 

 and index are not the same in all the groups. Racial differences 

 appear. The Eskimo and Indian ears are the longest, the negro 

 ears are the shortest, the white are in between in length. The 

 Eskimo and Indian ears are the broadest also, and the white 

 and negro ears are equal to each other in breadth. The result 

 is that the index of the Eskimo and Indian ears is low and that 

 of the negro is high, with the white in between.
