AS to the black Coral, the true Kind is so rare, that it is almost impossible to meet with it; for all that we now have, is only a Sort of Plant that is petrified in the Water, which some have call'd Antipathes; but it is entirely different from the true Coral, being very light, and more like Horn than Coral; whereas the true Sort is heavy, of a reddish black Colour, and very rough; and with the utmost Diligence I have met with some, but in very little Pieces, no bigger than the End of one's Finger; tho' I have a Piece of the common black Coral, of about two Foot long. As to the Coralloides, it is nothing else but white Coral that is not brought to its Perfection, and is of no manner of Use, yet it is sometimes sold instead of the White, tho' it is easy to distinguish, it being large, light, and imperfectly form'd.
