CRANIA AMERICANA. 



Remarks. — In the above scale of results, the skulls from the mounds have 

 been classed w^ith the Toltecan division, and those from the caves of Steubenville, 

 &C.5 with the Barbarous tribes. The great size of the Steubenville crania has 

 considerably enhanced the mean internal capacity of the heads of the Barbarous 

 Nations, so that it exceeds that of the Flatheads of Columbia river; but the latter, 

 as heretofore stated, compare fairly with the average of the entire race. It is 

 curious to observe, however, that the Barbarous Nations possess a larger brain by 

 five and a half cubic inches, than the Toltecans ; while, on the other hand, the 

 Toltecans possess a greater relative capacity of the anterior chamber of the skull, 

 in the proportion of 42.3 to 41.8. Again, the coronal region, though absolutely 

 greater in the Barbarous tribes, is rather larger in proportion in the Demi-civilised 

 tribes ; and the Facial Angle is much the same in both, and may be assumed, for 

 the race, at seventy-Jive degrees. 



In conclusion, the author is of the opinion that the facts contained in this 

 work tend to sustain the following propositions : 



1st. That the American Race differs essentially from all others, not excepting 

 the Mongolian; nor do the feeble analogies of language, and the more obvious ones 

 in civil and religious institutions and the arts, denote anything beyond casual or 

 colonial communication with the Asiatic nations ; and even these analogies may 

 perhaps be accounted for, as Humboldt has suggested, in the mere coincidence 

 arising from similar wants and impulses in nations inhabiting similar latitudes. 



2d. That the American nations, excepting the Polar tribes, are of one Race 

 and one species, but of two great Families, which resemble each other in physical, 

 but differ in intellectual character. 



3d. That the cranial remains discovered in the Mounds, from Peru to 

 Wisconsin, belong to the same race, and probably to the Toltecan family. 



Note. — On the Internal Capacity of the Cranium in the different Races of Men. — Having 

 subjected the skulls in my possession, and such also as I could obtain from my friends, to the internal 

 capacity measurement already described, I have obtained the following results. The mean of the 

 American Race, (omitting the fraction) is repeated here merely to complete the Table. The skulls of 

 idiots and persons under age were of course rejected.
