being necessitated to restore it, and (as he affirm’d) it was known within some while after that the said Venetian Gentleman did in Constantinople sell that Carbuncle to the then Grand Seignior, newly come to the Empire, for a hundred thousand Crowns. And this is what I can say concerning Carbuncles, and this is not a little at least as to the first part of this account, where our Cellini affirms himself to have seen a Real Carbuncle with his own Eyes, especially since this Author appears wary in what he delivers, and is inclin’d rather to lessen, than increase the wonder of it.  And his Testimony is the more considerable, because though he were born a Subject neither to the Pope nor the then King of France (that Royal Virtuoso Francis the first) yet both the one and the other of those Princes imploy’d him much about making of their Noblest Jewels.  What is now reported concerning a Shining Substance to be seen in one of the Islands about Scotland, were very improper for me to mention to Sr. Robert Morray, to whom the first Information was Originally brought, and from whom I expect a farther (for I scarce dare expect a convincing) account of it.  But I must not omit that some Virtuoso questioning me the other day at White-Hall about Mr. Claytons Diamond, and meeting amongst them an Ingenious Dutch Gentleman, whose Father was long Embassador for the Netherlands in England, I Learn’d of him, that, he is acquainted with a person, whose Name he told (but I do not well remember it) who was Admiral of the Dutch in the East-Indies, and who assur’d this Gentleman Monsieur Boreel, that at his return from thence he brought back with him into Holland a Stone, which though it look’d but like a Pale Dull Diamond, such as he saw Mr. Claytons to be, yet was it a Real Carbuncle, and did without rubbing shine so much, that when the Admiral had occasion to open a Chest which he kept under Deck in a Dark place, where ’twas forbidden to bring Candles for fear of Mischances, as soon as he open’d the Trunck, the Stone would by its Native Light, shine so as to Illustrate a great part of it, and this Gentleman having very civilly and readily granted me the request I made him, to Write to the Admiral, who is yet alive in Holland, (and probably may still have the Jewel by him,) for a particular account of this Stone, I hope ere long to receive it, which will be the more welcome to me, not onely because so unlikely a thing needs a cleer evidence, but because I have had some suspition of that (supposing the truth of the thing) what may be a shining Stone in a very hot Countrey as the East-Indies, may perhaps cease to be so (at least in certain seasons,) in one as cold as Holland.  For I observ’d in the Diamond I send you an account of, that not onely rubbing but a very moderate degree of warmth, though excited by other wayes, would make it shine a little.  And
