tubercle in the negro ear may prevent the hnes from forming 

 above Darwin's tubercle as the latter undegoes retrograde meta- 

 morphosis. 



The satyr tubercle is large in the negro ear, small in the white 

 ear, and intermediate in the Filipino ear. 



The helix of the negro ear is broad, the helix of the Filipino 

 ear is narrow, and the helix of the white ear is intermediate. The 

 broadness of the helix in the negro ear is especially well seen in 

 the upper border in the region of the satyr tubercle, and this 

 border of the ear is horizontal and at right angles to the ear 

 base. There is evidence of greater inrolling of the negro ear in 

 this part, which accounts for the shape of the negro ear, quad- 

 rangular, or pentagonoid, and also for its small size, and its 

 greater breadth and less height or length, its short, broad concha, 

 its small base and long true ear diameter. 



The lobule is absent or small more frequently from the ears 

 of the negroes and Filipinos than from the ears of the whites, 

 and it is absent or small more frequently from the ears of the 

 women than of the men. Keith (13) gives an increasing size 

 of the lobule in the following order: Orang, chimpanzee, gorilla, 

 negro, British. According to Martin the lobule is absent often- 

 est in the negroes, less in the Asiatics and least in the Europeans. 

 It is also absent more frequently among the defectives than 

 among normal individual (Bertillon). 



The helix and other parts of the ear may be examined for their 

 relative projection from the head, and as this determines in part 

 the Hypo-, Meso and Hyper types of the ear it will lead up natur- 

 ally to a consideration of these three types. 



The negro men have projecting helices, the white men have 

 projecting anthelices, the Filipino men resemble both the white 

 and negro men, and the negro and Filipino women resemble 

 the white men more than they do the negro men. 



The lobule and the inferior border of the helix: This part of 

 the ear is turned from the head in the negro men, and in toward 

 the head in the white men, and the negro women resemble the 

 white men in this respect.
