But to refer this Discourse of Animals to their proper places, I shall add, that though one should suppose, or it should be prov’d by Observations; that several of these kinds of Plants are accidentally produc’d by a casual _putrifaction_, I see not any great reason to question, but that, notwithstanding its own production was as ’twere casual, yet it may germinate and produce seed, and by it propagate its own, that is, a new Species. For we do not know, but that the Omnipotent and All-wise Creator might as directly design the structure of such a Vegetable, or such an Animal to be produc’d out of such or such a _putrifaction_ or change of this or that body, towards the constitution or structure of which, he knew it necessary, or thought it fit to make it an ingredient; as that the digestion or moderate heating of an Egg, either by the Female, or the Sun, or the heat of the Fire, or the like, should produce this or that Bird; or that _Putrifactive_ and warm steams should, out of the blowings, as they call them, that is, the Eggs of a Flie, produce a living Magot, and that, by degrees, be turn’d into an _Aurelia_, and that, by a longer and a proportion’d heat, be _transmuted_ into a Fly. Nor need we therefore to suppose it the more imperfect in its kind, then the more compounded Vegetable or Animal of which it is a part; for he might as compleatly furnish it with all kinds of contrivances necessary for its own existence, and the propagation of its own Species, and yet make it a part of a more compounded body: as a Clock-maker might make a Set of Chimes to be a part of a Clock, and yet, when the watch part or striking part are taken away, and the hindrances of its motion remov’d, this chiming part may go as accurately, and strike its tune as exactly, as if it were still a part of the compounded _Automaton_. So, though the original cause, or seminal principle from which this minute Plant on Rose leaves did spring; were, before the corruption caus’d by the Mill-dew, a component part of the leaf on which it grew, and did serve as a _coagent_ in the production and constitution of it, yet might it be so consummate, as to produce a seed which might have a power of propagating the same species: the works of the Creator seeming of such an excellency, that though they are unable to help to the perfecting of the more compounded existence of the greater Plant or Animal, they may have notwithstanding an ability of acting singly upon their own internal principle, so as to produce a Vegetable body, though of a less compounded nature, and to proceed so farr in the method of other Vegetables, as to bear flowers and seeds, which may be capable of propagating the like. So that the little cases which appear to grow on the top of the slender stalks, may, for ought I know, though I should suppose them to spring from the perverting of the usual course of the parent Vegetable, contain a seed, which, being scatter’d on other leaves of the
