"In America, likewise, tradition refers the knowledge of cultivated plants and domestic animals, and the art of tilling the earth, to some fabulous person who descended from the gods, or suddenly made his appearance among their ancestors, such as the Manco-Capac of the Peruvians, and the Xolotl and the Xiuhtlato of the Tollecas and Chicimecas. "The remains of ancient sculpture and architecture spread over Mexico, Yucatan, and Chiapa, as well as over the high plain of Quito and other parts of South America, and the extensive works of art, consisting of fortifications and other relics, discovered in the Tenessi country, as well as in the inland parts of New Mexico on the Rio Gila, afford some further support to the hypothesis of M. Martius. "The possession of arts and acquirements, the most simple improvements of human life, and such as belong to the very infancy of human society, distinctively appropriate, and the origin of which is recorded by mythical legends peculiar to each division of mankind, seems to carry back the era of their separation to the first ages of the world." With regard to the physical character of the Americans, it appears, according to Dr Martius, that the principal characteristic is the truncation, or flatness, of the occipital portion of the cranium; the forehead wide, but low, supposed upon rather insufficient data to be moulded to this shape by artificial means; and the nose arched. In the new as in the old continent, the diversities of physical character do not correspond with the ethnical divisions. The principal criterion of the latter adopted by Dr Prichard is the affinity of languages; and, when this is insufficient to found any probable opinions, conjectures derived from geographical or traditional evidence are called in aid. Upon these grounds the Americans are arranged and described by the author, into the details of which, for the same reason as before stated, we regret not being able to follow him.
