However therefore this complexion was first acquired, it is evidently maintained by generation, and by the tincture of the skin as a spermatical part traduced from father unto Son; so that they which are strangers contract it not, and the Natives which transmigrate, omit it not without commixture, and that after divers generations. And this affection (if the story were true) might wonderfully be confirmed, by what _Maginus_ and others relate of the Emperour of _Æthiopia_, or _Prester John_, who derived from _Solomon_ is not yet descended into the hue of his Country, but remains a _Mulatto_, that is, of a Mongril complexion unto this day. Now although we conceive this blackness to be seminal, yet are we not of _Herodotus_ conceit, that their seed is black. An opinion long ago rejected by _Aristotle_, and since by sense and enquiry. His assertion against the Historian was probable, that all seed was white; that is without great controversie in viviparous Animals, and such as have Testicles, or preparing vessels wherein it receives a manifest dealbation. And not only in them, but (for ought I know) in Fishes not abating the seed of Plants; whereof at least in most though the skin and covering be black, yet is the seed and fructifying part not so; as may be observed in the seeds of _Onyons_, _Pyonie_ and _Basil_. Most controvertible it seems in the spawn of Frogs, and Lobsters, whereof notwithstanding at the very first the spawn is white, contracting by degrees a blackness, answerable in the one unto the colour of the shell, in the other unto the Porwigle or Tadpole; that is that Animall which first proceedeth from it. And thus may it also be in the generation and sperm of Negroes; that being first and in its naturals white, but upon separation of parts, accidents before invisible become apparent; there arising a shadow or dark efflorescence in the outside; whereby not only their legitimate and timely births, but their abortions are also dusky, before they have felt the scorch and fervor of the Sun.
