From the animal creation we may obtain a further confirmation of what has been above advanced. In Dauphiny, it has been observed that all the hogs are black; and that on the other side of the Rhone, in Vivarais, where it is more cold than in Dauphiny, all the hogs are white. There is no probability that the inhabitants of one of these two provinces should have agreed to breed none but blackhogs, and the other none but white ones. To me it appears, that this difference arises solely from the variation in the temperature of the climate, combined, perhaps, with that of the food of the animals.
The few blacks who have been found in the Philippines, and other islands of the Indian Ocean, seem to originate from the Papous, or Negroes of New Guinea, whom the Europeans have not known much longer than half a century. Dampier discovered the most eastern part in 1700, and gave it the name ofNew Britain; we are still ignorant of its extent, yet we know that, so far as has been discovered, it is not very populous.
In those climates alone, then, where circumstances combine to create a constant and excessive heat, do we meet with negroes. This heat is necessary not only to the production, but even to the preservation of negroes; and where the heat, though violent, is not comparable to that of Senegal, the negro infants are so susceptible of the impressions of the air, that there is a necessity for keeping them during the first nine days in warm apartments; if this precaution is omitted, and they are exposed to the air soon after theirbirth, a convulsion in the jaw succeeds, which preventing them from receiving any sustenance, they presently die.
In the History of the Academy of Sciences we read, that M. Littre, in dissecting a negro, in 1702, remarked, that the point of the glands which was not covered with the prepuce was black, and the rest perfectly white. From this observation it is evident, that the air is necessary to produce the blackness of negroes. Their children are born white, or rather red, like those of other men, but two or three days after they change to a tawny yellow, which gradually darkens till the seventh or eighth day, when they are completely black. All children two or three days after their birth have a kind of jaundice, which in white children is transitory, and leaves no impression upon the skin; but in negro children it gives a colour to the skin, and continues to grow more and more black. M. Kolbe mentions having observed this fact among the children of Hottentots. This jaundice, however, and the impression of the air, seem to be only occasional, and not the primary cause of this blackness; since it is remarked, that the children of negroes have, the instant of their birth, ablackness in the genitals, and at the root of the nails. The action of the air and the jaundice may serve to extend this blackness, but it is certain that the principle of it is communicated to the children by their parents; that in whatever country a negro may be born, he will be as black as if he had been brought forth in his own; and if there is any difference in the first generation it is imperceptible; from this circumstance, however, we are not to suppose, that after a certain number of generations, the colour would not undergo a very sensible change.
Many have been the researches of anatomists respecting this black colour. Some pretend, that it is neither in the skin, nor in the epidermis, but in the cellular membrane which is between them; that this membrane, though washed, and held ever so long in warm water, does not change colour, while the skin, and the surface of the skin, appear to be nearly as white as those of other men. Dr. Town, in his letter to the Royal Society, and a few others, maintain, that the blood is black in negroes, and from which cause their colour originates; a fact which I am inclined to believe, from having remarked, that among ourselves theblood of those who are tawny, yellow, or brown, is proportionally more black than that of others.
According to M. Barrere, this colour of the negroes is produced by the bile, which in them is not yellow, but always black as ink; of which he affirms he received certain proof from several negroes which he had occasion to dissect at Cayenne. When the bile is diffused, it tinges the skin of white people yellow; and it is probable, that if the former were black, the latter would be black also. But as when the overflow of the bile ceases, the skin recovers its natural whiteness, so on this principle there is a necessity for supposing that in the negroes there is always an overflow of bile, or at least that, as M. Barrere observes, it is so abundant, as naturally to secrete itself in the epidermis, in a quantity sufficient to communicate this black colour. It probable that the bile and blood of negroes are more brown than those of white men, as their skin is more black. But one of these facts can never be admitted as an explanation of the cause of the other; for if it is the blood or bile which, by its blackness, communicates this colour to the skin, then, instead of inquiring why the skin of negroes isblack, we must inquire why their bile or blood is so; and thus, by deviating from the question, we find ourselves more than ever remote from the solution of it. For my own part, I own I have always been of opinion, that the cause which renders a Spaniard more brown than a Frenchman, and a Moor than a Spaniard, is also the cause which renders a Negro blacker than a Moor. At present I mean not to enquire how this cause acts, but only to ascertain that it does act, and that its effects are the more considerable, in proportion to the force and continuance of action.
Of the blackness of the skin, the principal cause is the heat of the climate. When this heat is excessive, as at Senegal, and in Guinea, the inhabitants are entirely black; when it is rather less violent, as on the eastern coasts of Africa, they are of a shade more light; when it becomes somewhat temperate, as in Barbary, Mogul, Arabia, &c. they are only brown; and in fine, when it is altogether temperate, as in Europe and in Asia, they are white; and the varieties there remarked proceed solely from the mode of living. All the Tartars, for example, are tawny, while the Europeans, who live in the same latitude, are white. This differenceclearly arises from the former being always exposed to the air; having no towns nor fixed habitations; sleeping upon the earth, and living coarsely and savagely. These circumstances are sufficient to render them less white than the Europeans, who want nothing to render life comfortable and agreeable. Why are the Chinese whiter than the Tartars, whom they resemble in all their features? Certainly from the above reasons.
When cold becomes extreme, it produces effects similar to those of excessive heat. The Samoiedes, Laplanders, and Greenlanders, are very tawny; and it is even asserted, that some Greenlanders are as black as those of Africa. Here the two extremes meet. Violent cold and violent heat produce the same effect upon the skin, because these two causes act by a quality which they possess in common. Dryness of the air is this quality; and which cold is as equally productive as intense heat; by either the skin may be dried, and rendered as tawny as what we find it among the Laplanders. Cold compresses all the productions of nature; and thus it is that the Laplanders, who are perpetually exposed to the rigours of frost, are the smallest of the human species.
The most temperate climate is between the degrees of 40 and 50; where the human form is in its greatest perfection; and where we ought to form our ideas of the real and natural colour of man. Situated under this Zone the civilized countries are, Georgia, Circassia, the Ukraine, Turkey in Europe, Hungary, South Germany, Italy, Switzerland, France, and the North of Spain; of all which the inhabitants are the most beautiful people in the world.
As the principal cause of the colour of mankind, we ought to consider the climate; the effects of nourishment are less upon the colour, yet upon the form they are prodigious. Food which is gross, unwholesome, or badly prepared, produces a degeneracy in the human species; and in all countries where the people are wretchedly fed, they are ugly, and badly shaped. Even in France, the inhabitants of country places are more ugly than those of towns; and I have often remarked, that in villages where poverty and distress were less prevalent, the people were in person more shapely, and in visage less ugly. The air and the soil have also great influence on the form of men, animals, and vegetables. The peasantswho live on hilly grounds are more active, nimble, well-shaped, and lively, than those who live in the neighbouring vallies, where the air is thick and unrefined.
Horses from Spain or Barbary cannot be perpetuated in France; in the very first generation they degenerate, and by the third or fourth they become downright French horses. So striking is the influence of climate and food upon animals, that the effects of either are well known, and though they are less sudden and less apparent upon men, yet, from analogy, we must conclude they extend to the human species, and that in the varieties we find therein, they plainly manifest themselves.
From every circumstance may we obtain a proof, that mankind are not composed of species essentially different from each other; that, on the contrary, there was originally but one species, which, after being multiplied and diffused over the whole surface of the earth, underwent divers changes from the influence of the climate, food, mode of living, epidemical distempers, and the intermixture of individuals, more or less resembling each other; that at first these alterations were less conspicuous, and confined to individuals; that afterwards, fromcontinued action, they formed specific varieties; that these varieties have been perpetuated from generation to generation, in the same manner as deformities and diseases pass from parents to their children, and that in fine, as they were first produced by a concurrence of external and accidental causes, and have been confirmed and rendered permanent by time, and by the continual action of these causes, so it is highly probable that in time they would gradually disappear, or become different from what they at present are, if such causes were no longer to subsist, or if they were in any material point to vary.
