But that _putrifying_ animal substances may produce animals of an inferior kind, I see not any so very great a difficulty, but that one may, without much absurdity, admit: For as there may be multitudes of contrivances that go to the making up of one compleat Animate body; so, That some of those _coadjutors_, in the perfect existence and life of it, may be vitiated, and the life of the whole destroyed, and yet several of the constituting contrivances remain intire, I cannot think it beyond imagination or possibility; no more then that a like accidental process, as I have elswhere hinted, may also be supposed to explicate the method of Nature in the _Metamorphosis_ of Plants. And though the difference between a Plant and an Animal be very great, yet I have not hitherto met with any so _cogent_ an Argument, as to make me positive in affirming these two to be altogether _Heterogeneous_ and of quite differing kinds of Nature: And besides, as there are many _Zoophyts_, and sensitive Plants (divers of which I have seen, which are of a middle nature, and seem to be Natures transition from one degree to another, which may be observ’d in all her other passages, wherein she is very seldom observ’d to leap from one step to another) so have we, in some Authors, Instances of Plants turning into Animals, and Animals into Plants, and the like; and some other very strange (because unheeded) proceedings of Nature; something of which kind may be met with, in the description of the _Water-Gnat_, though it be not altogether so direct to the present purpose.
