Lastly, Whereas the _Africans_ are conceived to be more peculiarly scorched and torrified from the Sun, by addition of driness from the soil, from want and defect of water, it will not excuse the doubt. For the parts which the _Negroes_ possess, are not so void of Rivers and moisture, as is presumed; for on the other side the mountains of the Moon, in that great tract called _Zanzibar_, there are the mighty Rivers of _Suama_ and _Spirito Santo_; on this side, the great River _Zaire_, the mighty _Nile_ and _Niger_; which do not only moisten and contemperate the air by their exhalations, but refresh and humectate the earth by their annual Inundations. Beside, in that part of _Africa_, which with all disadvantage is most dry, that is, in situation between the Tropicks, defect of Rivers and inundations, as also abundance of Sands, the people are not esteemed _Negroes_; and that is _Lybia_, which with the _Greeks_ carries the name of all _Africa_. A region so desert, dry and sandy, that Travellers (as _Leo_ reports) are fain to carry water on their Camels; whereof they find not a drop sometime in six or seven days. Yet is this Country accounted by Geographers no part of _terra Nigritarum_, and _Ptolomy_ placeth herein the _Leuco Æthiops_, or pale and Tawny _Moors_. Now the ground of this opinion might be the visible quality of Blackness observably produced by heat, fire and smoak; but especially with the Ancients the violent esteem they held of the heat of the Sun, in the hot or torrid Zone; conceiving that part unhabitable, and therefore that people in the vicinities or frontiers thereof, could not escape without this change of their complexions. But how far they were mistaken in this apprehension, modern Geography hath discovered: And as we have declared, there are many within this Zone whose complexions descend not so low as unto blackness. And if we should strictly insist hereon, the possibility might fall into question; that is, whether the heat of the Sun, whose fervour may swart a living part, and even black a dead or dissolving flesh, can yet in animals, whose parts are successive and in continual flux, produce this deep and perfect gloss of Blackness.
