CRANIA AMERICANA, 



PLATE XXXIX. 



DACOTA. 



I received this skull from the late Dr. Poole, of this city, but could obtaiH 

 no particulars, excepting the fact of its having belonged to a Sioux w^arrior of bad 

 character, and who w^as killed by some act of violence on the northwestern 

 frontier. The small squared head, the great comparative breadth between the 

 parietal bones, and indiflferent frontal development, correspond precisely with those 

 features as observed in the individuals of the Sioux delegation already mentioned.
