of which was scarce discernable; but upon the suffering it to suck, it
presently fill'd the skin of the belly, and of the six scolop'd embosments
on either side, as full as it could be stuft, the stomach and guts were as
full as they could hold; the _peristaltick_ motion of the gut grew quick,
and the justling motion of II accordingly; multitudes of milk-white vessels
seem'd quickly filled, and turgid, which were perhaps the veins and
arteries and the Creature was so greedy, that though it could not contain
more, yet it continued sucking as fast as ever, and as fast emptying it
self behind: the digestion of this Creature must needs be very quick, for
though I perceiv'd the blood thicker and blacker when suck'd, yet, when in
the guts, it was of a very lovely ruby colour, and that part of it, which
was digested into the veins, seemed white; whence it appears, that a
further digestion of blood may make it milk, at least of a resembling
colour: What is else observable in the figure of this Creature, may be seen
by the 35. _Scheme_.

Observ. LV. _Of _Mites_._

The least of _Reptiles_ I have hitherto met with, is a Mite, a Creature
whereof there are some so very small, that the sharpest sight, unassisted
with Glasses, is not able to discern them, though, being white of
themselves, they move on a black and smooth surface; and the Eggs, out of
which these Creatures seem to be hatch'd, are yet smaller, those being
usually not above a four or five hundredth part of a well grown Mite, and
those well grown Mites not much above one hundredth of an inch in
thickness; so that according to this reckoning there may be no less then a
million of well grown Mites contain'd in a cubick inch, and five hundred
times as many Eggs.

Notwithstanding which minuteness a good _Microscope_ discovers those small
movable specks to be very prettily shap'd Insects, each of them furnished
with eight well shap'd and proportion'd legs, which are each of them
joynted or bendable in eight several places, or joynts, each of which is
covered, for the most part, with a very transparent shell, and the lower
end of the shell of each joynt is fringed with several small hairs; the
contrivance of the joynts seems the very same with that of Crabs and
Lobsters legs, and like those also, they are each of them terminated with a
very sharp claw or point; four of these legs are so placed, that they seem
to draw forwards, the
