Cole-black as ours, but partly of a Whitish Colour) in spight of Porphyries examples of Inseparable Accidents, I have seen a perfectly White Raven, as to Bill as well as Feathers, which I attentively considered, for fear of being impos’d upon.  And this recalls into my Memory, what a very Ingenious Physician has divers times related to me of a young Lady, to whom being call’d, he found that though she much complain’d of want of Health, yet there appear’d so little cause either in her Body, or her Condition to Guess that She did any more than fancy her self Sick, that scrupling to give her Physick, he perswaded her Friends rather to divert her Mind by little Journeys of Pleasure, in one of which going to Visit St. Winifrids Well, this Lady, who was a Catholick, and devout in her Religion, and a pretty while in the Water to perform some Devotions, and had occasion to fix her Eyes very attentively upon the Red pipple-stones, which in a scatter’d order made up a good part of those that appear’d through the water, and a while after growing Bigg, she was deliver’d of a Child, whose White Skin was Copiously speckl’d with spots of the Colour and Bignesss of those Stones, and though now this Child have already liv’d several years, yet she still retains them.  I have but two things to add concerning the Blackness of Negroes, the one is, that the Seat of that Colour seems to be but the thin Epidermes, or outward Skin, for I knew a young Negroe, who having been lightly Sick of the Small Pox or Measles, (for it was doubted which of the two was his Disease) I found by enquiry of a person that was concern’d for him, that in those places where the little Tumors had broke their passage through the Skin, when they were gone, they left Within specks behind them; And the lately commended Piso assures us, that having the opportunity in Brasil to Dissect many Negroes, he cleerly found that their Blackness went no deeper than the very outward Skin, which Cuticula or Epidermis being remov’d, the undermost Skin or Cutis appear’d just as White as that of Europaean Bodyes.  And the like has been affirmed to me by a Physician of our own, whom, hearing he had Dissectcd a Negroe here in England, I consulted about this particular.  The other thing to be here taken notice of concerning Negroes is, That having enquir’d of an Intelligent acquaintance of mine (who keeps in the Indies about 300. of them as well Women as Men to work in his Plantations,) whether their Children come Black into the world; he answer’d, That they did not, but were brought forth of almost the like Reddish Colour with our European Children; and having further enquir’d, how long it was before these Infants appear’d Black, be reply’d, that ’twas not wont to be many daies.  And agreeable to this account I find that, given us in a freshly publish’d French Book written by a Jesuit, that had good opportunity of Knowing
