The entire population of America, which, as it is for the most part of European extraction, is better known to us than that of many countries more contiguous--the entire population of America at the highest computation of the whole number of inhabitants on the globe, forms but a thirtieth part, and at the lowest computation, not a four-and-twentieth part of the whole. Widely extended as this thinly peopled continent is, the whole number of its inhabitants scarcely exceeds the population of a single great European state, such as either France or Germany, whose population, indeed, it about equals. Vegetation, indeed, is most rich and luxuriant in America; but the two most generous plants reared by human culture, and which are so closely connected with the primitive history of man--corn and the vine--were originally unknown in this quarter of the world. In the animal kingdom, America is far inferior to the other and more ancient continents of the globe. Many of the noblest and most beautiful species of animals did not exist there originally; and others again were found most unseemly in form, and most degenerate in nature. Some species of animals indigenous to that continent form but a feeble compensation for the absence of others, the most useful and most necessary for the purposes of husbandry and the domestic uses of man. We may boldly lay it down as a general proposition not to be taxed with error or exaggeration, that in the new hemisphere, vegetation is predominant, while in the old, animal force preponderates, and is more fully developed. This superiority is apparent not only in the comparative extent of population, but in the organic structure of the human form. Even the African tribes are far superior in bodily strength and agility to the aboriginal natives of America; and in point of longevity and fecundity, the latter are not to be compared with the Malayan race, and the Mongul tribes in the central or North-eastern parts of Asia, and in Southern Tartary, races with whom, in other respects, they seem to bear some analogy.
