The dimensions of the ear differ in the whites, it was shown by 

 Schwalbe, 1 with age, both the height and the breadth, but especially 

 the former, increasing up to at least the 70th year of age. The 

 module and ear index modify accordingly, the module increasing, the 

 index decreasing; in the words of the just mentioned author, 2 "the 

 ear in the aged is on the average absolutely longer and broader, but 

 relatively narrower, than that in the young adult. The same condi- 

 tions were found by the writer in the Indians, and they also exist 

 among the Kharga Egyptians. As seen from the following table, the 

 average height of the ear in the seventeen oldest men of the series is 

 to that of the seventeen youngest adults as 109.9 to. 100; the breadth 

 is as 104.2 to 100; the module or mean diameter as 107.7 to 100; 

 while the cephalic index is but as 94.6 to 100. We are dealing here 

 evidently with morphological conditions of wide extension, in which 

 racial or tribal differences are restricted to degree and other secon- 

 dary features of the phenomena.
