In respect to the general resemblance of the Indians, an able writer of a recent date, treating of this question, says,--“The testimony of all travellers goes to prove that the native Americans are possessed of certain physical characteristics which serve to identify them in places the most remote, while they assimilate not less in their moral character. There are also, in their multitudinous languages, some traces of a common origin; and it may be assumed as a fact, that no other race of men maintains so striking an analogy through all its subdivisions, and amidst all its varieties of physical circumstances,--while, at the same time, it is distinguished from all the other races by external peculiarities of form, but still more by the internal qualities of mind and intellect.” M. Bory de St. Vincent attempted to show that the American race includes four species besides the Esquimaux; but he appears to have failed in establishing his theory. Dr. Morton has paid great attention to the subject. He conducted his investigations by comparisons of the skulls of a vast number of different tribes, the results of which he has given to the public in his “_Crania Americana_.” He considers the most natural division to be into the _Toltecan_ and _American_; the former being half-civilized, and including the Peruvians and Mexicans; the latter embracing all the barbarous nations except the Esquimaux, whom he regards as of Mongolian origin. He divides each of these into subordinate groups, those of the American class being called the _Appalachian_, _Brazilian_, _Patagonian_, and _Fuegian_. The APPALACHIAN includes all those of North America except the Mexicans, together with those of South America north of the Amazon and east of the Andes. They are described thus. “The head is rounded, the nose large, salient, and aquiline, the eyes dark-brown, with little or no obliquity of position, the mouth large and straight, the teeth nearly vertical, and the whole face triangular. The neck is long, the chest broad, but rarely deep, the body and limbs muscular, seldom disposed to fatness.” In character, they “are warlike cruel, and unforgiving,” averse to the restraints of civilized life, and “have made but little progress in mental culture or the mechanic arts.” Of the BRAZILIAN it is said, that they are spread over a great part of South America east of the Andes, including the whole of Brazil and Paraguay between the River Amazon and 35 degrees of south latitude. In physical characteristics, they resemble the Appalachian; their nose is larger and more expanded, their mouth and lips also large. Their eyes are small, more or less oblique, and farther apart, the neck short and thick, body and limbs stout and full, to clumsiness. In mental character, it is said, that none of the American race are less susceptible of civilization, and what they are taught by compulsion seldom exceeds the humblest elements of knowledge.
