Morton's Crania Americana.

^'^ 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." Dr. Morton subjoins the following 



" Note on the internal capacity of the cranium iti the different 

 races of men. Having subjected the skulls in my possession, and 

 such also as I could obtain from piy friends, to the internal ca- 

 pacity measurement already described, I have obtained the follow- 

 ing results. The mean of the American race (omitting fractions) 

 is repeated here, merely to complete the table. The skulls of 

 idiots, and persons under age, were of course rejected. 



" 1st. The Caucasians were, with a single exception, derived 

 from the lowest and least educated class of society. It is proper, 

 however, to mention that but three Hindoos are admitted in the 

 whole number, because the skulls of these people are probably 

 smaller than those of any other existing nation. For example, 

 seventeen Hindoo heads give a mean of but seventy-five cubic 

 inches ; and the three received into the table are taken at that 

 average. To be more specific, we will give, in detail, the num- 

 ber of individuals of each nation, as far as ascertained. 



Anglo-Americans, 6 



German, Swiss and Dutch, 7 



Celtic, Irish and Scots, 7 



English, . . . . . . . . ... . ,. 4 



Guanche, (Lybian,) ........ 1 



Spanish, . 1 



Hindoo, 3 



Europeans not ascertained, 23 . 



Total, 53 



" 2d. The Mongolians measured, consist of Chinese and Eski- 

 maux, and what is worthy of remark, three of the latter give a 

 mean of 86 cubic inches, while seven Chinese give but 82.
