Morton'' s Crania Americana. 



as the other. The structure of his mind appears to be different 

 from that of the white man, nor can the two harmonize in their 

 social relations except on the most limited scale. Every one 

 knows, however, that the mind expands by culture ; nor can we 

 yet tell how near the Indian would approach the Caucasian after 

 education had been bestowed on a single family through several 

 successive generations." p. 82.* 



The following are parts of Dr. Morton's table of "mean results," 

 given from his whole measurements. 



Remarks. — " The barbarous nations possess a larger brain by 

 5^ 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-civilized tribes ; 

 and the facial angle is much the same in both, and may be as- 

 sumed, for the race, at 75 degrees. 



" In conclusion, the author is of the opinion that the facts con- 

 tained in this work tend to sustain the following propositions : 



" 1st. That the American race differs essentially from all others, 

 not excepting the Mongolians ; nor do the feeble analogies of lan- 

 guage, and the more obvious ones, in civil and religious institu- 

 tions and the arts, denote any thing beyond casual or colonial 

 communication with the Asiatic nations ; and even those analo- 

 gies may perhaps be accounted for, as Humboldt has suggested, 

 in the mere coincidence arising from similar wants and impulses 

 in nations inhabiting similar latitudes. 



* Dr. Morton adds that the Indians are extremely defective in comprehending 

 every thing relating to numbers, and we may remark that Mr. Combe, in his lec- 

 tures in New Haven, showed the great deficiency of the organ of number in their 

 skulls.
