ll 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 capabale 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
same Plant, may produce a Plant of much the same kind.

Nor are Damask-Rose leaves the onely leaves that produce these kinds of
Vegetable sproutings; for I have observ'd them also in several other kinds
of Rose leaves, and on the leaves of several sorts of Briers, and on
Bramble leaves they are oftentimes to be found in very great clusters; so
that I have found in one cluster, three, four, or five hundred of them,
making a very conspicuous black spot or scab on the back side of the leaf.
