 may be proper to premie here, that it was of abolute neceity to the upporting that Gentleman's Sytem of the Solution of Foils at the Deluge, that this hould be proved to be one, becaue he gives it as a Certainty, that all the foile Corals have been in a State of Solution; which, had they ever been of another Nature, they could not, according to his own Sytem, have been. If his Sytem be jut in this Point, I have Proofs, that, whatever he might conclude from it, it really makes for the antient Opinion; for, whatever may have been the Cae in regard to the foile Corals in the Doctor's Cabinet, I have one which I very lately took up from 25 Feet deep in a Clay-pit in the Neighbourhood of London: Which hews evidently, that it never has been in a State of Solution, and mut have been therefore, according to his own Sytem, an organized Body; for there are Numbers of mall Balani affixed on it, and that not immered in, or laid on it in irregular and uncertain Potures (as mut have been the Cae, if they had accidentally been lodged in and on it at the Time of its concreting in the Waters of the Deluge) but fixed in the very Manner in which they are found when living and in their natural Poture: This it is impoible they hould be, if ever they had been dilodged from it; as they mut have been, if ever it had been in a State of Solution. Nor are we to imagine, that the foile Corals have been in a State of Solution, becaue they have often very different Matter from the Coralline in their Contitution; nay, ometimes eem almot wholly compoed of uch: For we frequently find foile Wood, which, according to that Gentleman's own Sytem, never has been in a State of Solution, aturated in like manner with the Matter of the common Pyrites, and ometimes eeming wholly compoed of it. And this very Specimen of Coral of mine, which, it is evident, never has been in a State of Solution, is yet almot wholly converted into an Agate.

To this it may be added, that after all the Pains that Gentleman has taken to prove that Corals are Foils, and formed by mere Appoition of Corpucles, not by Organization; his chemical Analyis of red Coral, has brought him to a Neceity of allowing, that there is omething of another Nature in them; And how can he imagine this came there? When I Coral, for its Subtance is like that of Stones: Its Colour is red, and its Shape cylindrical, in ome ort reembling a Root. It grows in the Sea. can
