Breadth of Mouth. — The breadth of the mouth, taken between the 

 most distal points at which the mucous membrane in the corners of 

 the mouth joins the skin, is broader in the Chippewa than in the 

 Indians of the Southwest in general, and considerably broader in 

 both than in Old-American whites. In this respect again some slight 

 allowance must be made, because our series includes so many old 

 persons in whom, before the alveolar processes suffer absorption, the 

 mouth averages larger than in young adults. 



The comparative figures below show an additional fact of interest 

 — the difference between the breadth of the mouth in the two sexes 

 is greater among whites than among the Indians; in other words, the 

 mouth in white females is relatively smaller, compared with that of 

 the males, than in any of the Indians.

The Left Ear. — The external ear, as well known, is a structure of 

 anthropological interest. The selection of the left ear for purposes of 

 measurement is due merely to the greater ease of manipulating the 

 instrument on the left side.
