g you with more descriptions, be plainly enough perceiv'd
by the _Scheme_, the hinder part or belly consisting of eight several
jointed parts, namely, ABCDEFGH, of the first _Figure_, from the midst of
each of which, on either side issued out three or four small brisles or
hairs, I, I, I, I, I, the tail was divided into two parts of very differing
make; one of them, namely, K, having many tufts of hair or brisles, which
seem'd to serve both for the finns and tail, for the Oars and Ruder of this
little creature, wherewith it was able, by frisking and bending its body
nimbly to and fro, to move himself any whither, and to skull and steer
himself as he pleas'd, the other part, L, seem'd to be, as 'twere, the
ninth division of his belly, and had many single brisles on either side.
From the end V, of which, through the whole belly, there was a kind of Gut
of a darker colour, MMM, wherein, by certain _Peristaltick_ motions there
was a kind of black substance mov'd upwards and downwards through it from
the orbicular part of it, N, (which seem'd the _Ventricle_, or stomach) to
the tail V, and so back again, which _peristaltick_ motion I have observ'd
also in a Louse, a Gnat, and several other kinds of transparent body'd
Flies. The _Thorax_ or chest of this creature OOOO, was thick and short,
and pretty transparent, for through it I could see the white heart (which
is the colour also of the bloud in these, and most other Insects) to beat,
and several other kind of motions. It was bestuck and adorn'd up and down
with several tufts of brisles, such as are pointed out by P, P, P, P, the
head Q was likewise bestuck with several of those tufts, SSS; it was broad
and short, had two black eyes, TT, which I could not perceive at all
pearl'd, as they afterwards appear'd, and two small horns, RR, such as I
formerly describ'd.

Both its motion and rest is very strange, and pleasant, and differing from
those of most other creatures I have observ'd; for, where it ceases from
moving its body, the tail of it seeming much lighter then the rest of its
body, and a little lighter then the water it swims in, presently boys it up
to the top of the water, where it hangs suspended with the head always
downward; and like our _Antipodes_, if they do by a frisk get below that
superficies, they presently ascend again unto it, if they cease moving,
until they tread, as it were, under that superficies with their tails; the
hanging of these in this posture, pu
