Whether the last mentioned people, after their dispersion from their great capital in the province of Chiapa, were or were not the nucleus around which the many distinct tribes that afterward constituted the people of the great Mexican empire, all our inquiries are unable clearly to establish; still, there are strong evidences in favor of that opinion. Hence the name Tultecan, by which we have designated the primeval inhabitants of this continent, and the authors of the extensive arts, the ruins of which have been noticed, may be identical with the _Toultecs_. All agree that there was a race of people existing for an unknown period of time in Central America before the Toultecs, the Aztecs, or the Chichimecas appeared in the beautiful Mexican valley. This agreement, in connection with the antique relics found on the site of the famous Palencian city, and the indisputable evidences of the superior knowledge of the ancient Palenquans, renders the conclusion to which we have arrived inevitable. It is also extremely probable, from the analogy observed among the arts of succeeding inhabitants of Mexico, the similarity of their manners and customs, and their knowledge of the arts and sciences, in which the original Tultecans were so highly distinguished, that a part of the latter people, after the destruction of their great capital, was united with the former. This probability, though unnoticed by writers upon the early inhabitants of Mexico, amounts, in our mind, to conviction. It forms a basis to the only conclusion which presents itself in attempting to explain the origin of the extraordinary arts now found throughout the Mexican valley, and in other parts of that once extensive empire. The inference is not less conclusive in relation to the people with whom the original Tultiques became united, and with whom they in part constituted the subsequent great nation of Mexicans. This people were clearly the previous inhabitants of our own western states. Their arts are distinctly traced from Wisconsin and Missouri Territories, all the way into the valley of Mexico. Among those which now characterize that valley, are to be seen numerous specimens so closely resembling the relics of the United States, that no other inference can be drawn from the fact, than that they were the work of the same people. Still, it will be observed that others exist in Mexico, which as plainly show the existence of a distinct and peculiar class of men. The most remarkable of these are found among the ruins of Palenque, Copan, and at other places in the province of Chiapa, Yucatan, and Guatemala. Others again exist, scattered throughout both Peru and Mexico, among the Pacific Islands, and west of the Rocky Mountains, which differ in many striking particulars from those of this country, from those of Palenque, and among themselves. This is strongly in evidence of the historical fact, that the ancient Mexicans were composed of numerous and very different tribes of people.
