Now whereas if it be plac'd on its back, with its
belly upwards, as it is in the 35. _Scheme_, it seems in several Positions
to have a resemblance of chaps, or jaws, as is represented in the Figure by
EE, yet in other postures those dark strokes disappear; and having kept
several of them in a box for two or three dayes, so that for all that time
they had nothing to feed on, I found, upon letting one creep on my hand,
that it immediately fell to sucking, and did neither seem to thrust its
nose very deep into the skin, nor to open any kind of mouth, but I could
plainly perceive a small current of blood, which came directly from its
snout, and past into its belly; and about A there seem'd a contrivance,
somewhat resembling a Pump, pair of Bellows, or Heart, for by a very swift
_systole_ and _diastole_ the blood seem'd drawn from the nose, and forced
into the body. It did not seem at all, though I viewed it a good while as
it was sucking, to thrust more of its nose into the skin then the very
snout D, nor did it cause the least discernable pain, and yet the blood
seem'd to run through its head very quick and freely, so that it seems
there is no part of the skin but the blood is dispers'd into, nay, even
into the _cuticula_; for had it thrust its whole nose in from D to CC, it
would not have amounted to the supposed thickness of that _tegument_, the
length of the nose being not more then a three hundredth part of an inch.
