CRANIA AMERICANA. 



PLATE XXXIV. 



POTOWATOMIE. 



A skull of a genuine Potowatomie, of whose history, however, nothing is 

 known. It is remarkable for its capacity behind the ears, and for the great length 

 and flatness of the coronal region. I received it from my friend Dr. Walker, of 

 the United States Army, who obtained it while stationed in Michigan, which is 

 the native seat of this tribe.
