From what I have myself observed, independent of the information of travellers, I have no doubt, but that they are only negroes degenerated from their race, and not a peculiar and established species of men. In a word, they are among the negroes, what Wafer says, the white Indians are among the yellow Indians of Darien, and what the Chacrelas and the Bedas are among the brown Indians of the East. Still more singular is it that this variation never happens but from black to white, and also that all the nations of the East Indies, of Africa, and of America, in which those white men are found, are in the same latitude. The isthmus of Darien, the country of the negroes, and Ceylon, are absolutely under the same line. White then appears to be the primitive colour of Nature, which climate, food, and manners, alter, and even change into yellow, brown, or black; and which, in certain circumstances, reappears, though by no means equal to its original whiteness on account of its corruption from the causes here mentioned.
Nature, in her full perfection, made men white; and, reduced to the last stage of adulteration, she renders them white again. But the natural white is widely different from the individual, or accidental white. In plants, as well as in men and animals, do we find examples of this fact. The white rose, &c. differs greatly in point of whiteness from the red rose, which becomes white by the cold evenings and frosty chills of autumn.
A further proof that these white men are merely degenerated individuals, is their being less strong and vigorous than others, and their eyes being extremely weak. The fact will appear less extraordinary, when we recollect, that, among ourselves, very fair men have very weak eyes, and that such people are often slow of hearing. It is pretended that dogs absolutely white, are deaf. Whether the observation is generally just, I know not, but in a number of instances I have seen it confirmed.
The Indians of Peru, like the natives of the Isthmus, are copper-coloured; those especially who live near the sea, and in the plains. Those who live between the two ridges of the Cordeliers, are almost as white as the Europeans. Some live in Peru more than a league higher than others; and which elevation, with respect to the temperature of the climate, is equal to twenty leagues in latitude. All the native Indians, who dwell along the river of the Amazons, and in Guiana are tawny, and more or less red. The diversity of shades, says M. de la Condamine, is principally occasioned by the different temperature of the air, varied as it is, from the extreme heat of the torrid zone, to the cold occasioned by the vicinage of snow. Some of these Savages, as the Omaguas, flatten the visages of their children, by compressing the head between two planks; others pierce the nostrils, lips, or cheeks, for the reception of the bones of fishes, feathers, and other ornaments; and the greatest part bore their ears, and fill the hole with a large bunch of flowers, or herbs, which serves them for pendants. With respect to the Amazons, about whom so much has been said, I shall be silent. To those who have written on the subject I refer the reader; and when he has perused them he will not find sufficient proof to evince the actual existence of such women.
