The Mongolian, though less distinctive, is, however, sufficiently so, for his yellow skin, squat figure, beardless face, pyramidal head, and almond eyes, can scarcely be confounded with any other form of man. The Malay is less known, and therefore more difficult to describe. They are darker than the Mongol, though in some islands of a bright copper color, and indeed, vary from light olive to dark brown, and as in the case of the Australians, to deep black, but with no other approximation to the Negro. The vast populations known under the term Papuan, and mainly Malay, are doubtless extensively mixed with the Negro, for however remote the time, or whatever the form or mode, real negro populations have resided in tropical Asia, and left behind them these remains of their former existence. In some islands, like New Zealand, etc., the ruling dynasties or principal families have a considerable infusion of Caucasian blood, which is shown in their tall, erect form, more or less beard, fair complexion, and manly presence, and intellectually in their prompt and often intelligent acceptance of Christianity. The Indian, American, or Aboriginal, needs no description; suffice it to say that, from the mouth of the Columbia River to Cape Horn, they are the same species. It is quite possible, indeed probable, that some species, formerly existing on this continent, have disappeared—utterly perished. The investigations of Dr. Tschudi warrant this belief, though his nice discriminations in regard to some of the bones of the head are of little or no importance, as all this might be, and doubtless was, the result of artificial causes. But crania discovered in Southern Mexico and Yucatan, as well as in Peru and Brazil, are sufficient evidence to warrant the belief that a still inferior race did once really inhabit this continent, but whether aboriginal or brought here by some superior race, may never be known. The remains of ancient structures in Yucatan, in Peru, in Mexico, in Brazil, all over the southern portion of the continent, show simply the traces of Caucasian intrusion. It has been generally supposed that Columbus and his companions were the first white men that ever visited this continent, but it may have been discovered, and to a certain extent, occupied, at least certain localities occupied, before even Europe itself, or before the period of authentic history. Any one visiting Mexico, Puebla, or other cities of Spanish America, is amazed and bewildered with the contrast between the vast and magnificent structures that meet his eye, and the existing population. He involuntarily asks himself, “Can these people be the authors of all this art, this beauty, strength and magnificence? Can these miserable, barefooted, blanketed, idle and stolid-looking creatures have built these palaces, these churches, these bridges, these mighty structures, which seem to have been built for eternity itself, so strong and secure
