y hinted, it seems probable, that some kind of
wandring Mite may sow, as 'twere, the first seeds, or lay the first eggs,
in those places, which Nature has instructed them to know convenient for
the hatching and nourishing their young; and though perhaps the prime
Parent might be of a shape very differing from what the offspring, after a
little while, by reason of the substance they feed on, or the Region (as
'twere) they inhabite; yet perhaps even one of these alter'd progeny,
wandering again from its native soil, and lighting on by chance the same
place from whence its prime Parent came, and there settling, and planting,
may produce a generation of Mites of the same shapes and properties with
the first wandring Mite: And from some such accidents as these, I am very
apt to think, the most sorts of Animals, generally accounted _spontaneous_,
have their _origination_, and all those various sorts of Mites, that are to
be met with up and down in divers putrifying substances, may perhaps be all
of the same kind, and have sprung from one and the same sort of Mites at
the first.

Observ. LVI. _Of a small Creature hatch'd on a Vine._

There is, almost all the Spring and Summer time, a certain small, round,
white Cobweb, as 'twere, about the bigness of a Pea, which sticks very
close and fast to the stocks of Vines nayl'd against a warm wall: being
attentively viewed, they seem cover'd, upon the upper side of them, with a
small husk, not unlike the scale, or shell of a Wood-louse, or Hog-louse, a
small Insect usually found about rotten wood, which upon touching presently
rouls it self into the form of a peppercorn: Separating several of these
from the stock, I found them, with my _Microscope_, to consist of a shell,
which now seemed more likely to be the husk of one of these Insects: And
the fur seem'd a kind of cobweb, consisting of abundance of small
filaments, or sleaves of cobwebs. In the midst of this, if they were not
hatch'd, and run away before, the time of which hatching was usually about
the latter end of _June_, or beginning of _July_, I have often found
abundance of small brown Eggs, such as A and B in the second Figure of the
36. _Scheme_, much about the bigness of Mites Eggs; and at other times,
multitudes of small Insects, shaped exactly like that in the third Figure
marked with X. Its head large, almost half the bigness of its body, which
is usual in the _foetus_ of mos
