On the other side: although Nature cannot be said to imitate Art: yet it may fall out, that the effects of both may have some likeness. Those white Concretions which the Italians, from the place where they are found, call Confetti de Tibuli, are sometimes so like round Confects, and the rough kind of Sugar'd-Almonds, that by the eye they cannot be distinguish'd. To call these Petrify'd Sugar-Plums, were senseless. What if we find in some Stones under ground the likeness of a Cross? Doth not Sal Ammoniac often shoot into millions of little ones? Or do we find in other Stones the resemblance of Plants? Why not naturally there, as well as, in Frosty Weather, upon Glass Windows? Or as Salts sometimes figure themselves (as Sir Th. Brown, (a) (a) Relig. Med. and Dr. Daniel Cox (b) observe) into some likeness to the Plants whereof they are made. Nay, why not too, a Face, or other Animal Form? Since we see that there are divers (b) Phil. Trans. N. 108. Palm-Nuts which have the like. That the Volatile Salt of Harts-Horn, will shoot it self into the likeness of little branched Horns. That of Flesh or Blood, into the shape of little flat fibrous Tendons or Muscles, as I have often observ'd. And though I have not seen it my self, yet I have been told by one (c) (c) Sir Thomas Millington. that doth not use to phancy things, that the Volatile Salt of Vipers, will figure it self into the semblance of little Vipers. But there can be no convincing Argument given, why the Salts of Plants, or Animal Bodies, washed down with Rains, and lodged under ground; should not there be disposed into such like figures, as well as above it? Probably, in some cases, much better, as in a colder place; and where therefore the Work not being done in a hurry, but more slowly, may be so much the more regular. I shall now come to the Particulars, and leave the Reader to judge of them.
