CHARACTERISTICS OF THE EXTERNAL EAR 215 



and the noses of the negroes are broader than those of the whites. 

 The nose of those negroes with involuted ears is about the same 

 as those of the Hyper-phylo-morph type. 



Cephalic index and ear type: There is not the same regularity 

 of difference here as in the nasal index and ear type although 

 the negro woman shows the same regularity. In the latter the 

 head is relatively broad in the Hypo and relatively narrow in 

 the Hyper. The heads of the negroes with involuted ears are 

 relatively long and narrow, and as this is characteristic of the 

 negro head in general, we may attribute this to the fact that 

 involuted ears are characteristic of the negro also. 



Face index and ear type: The face index is better than the 

 cephalic index as a differentiator, but it not so good as the nasal 

 index. The face of the Hyper is relatively longer and narrower 

 than that of the Hypo or Meso. The face of the white man is 

 relatively longer and narrower than that of the negro man or 

 woman. 



EARS OF THE LIVING SUBJECTS 



The data for the ears of the Eskimos, American Indians, negroes 

 of Washington, D. C, and 'old whites' (3rd generation or over, 

 in America) came to me through Dr. Hrdlicka, and a part at 

 least has not before been published. The measurements were 

 made of the left ear only, of the Eskimo, by Dr. Riley D. Moore, 

 and of the others by Dr. Hrdlicka. Only the total length and 

 total breadth were taken. 



The Eskimo has the longest ears, the Indian is next, the 'old 

 white' third, the New Orleans students fourth and the negro has 

 the shortest ear. Comparing these with the morgue subjects, 

 the latter have slightly shorter ears (white and negro) and the 

 Filipinos have the shortest ears of all. The difference in length 

 between the 'old whites' and the New Orleans students may be 

 due to difference in age as the students are younger and ear 

 length increases with age. 



The Eskimo has the broadest ear, the Indian next, the 'old 

 white' next, the student next and the negro has the narrowest 

 ear. Compared with the morgue subjects the living have nar-
