o make it to be seen through, I can (assisting my
Eye) perceive it full of Vessels placed as thick as is possible to be
imagin'd, (the fat if there be any, being first removed) there appearing
then nothing but vessels, yet so as with a _Microscope_ may be seen
through, when they are extended. 2. That, if any one, as he is at dinner,
take a piece of flesh, and begin either at the head or tail of a _Muscle_,
he may divide it _in infinitum_ all along from head to tail, without
breaking any thing of that, called Flesh, only these transverse _Fibres_,
that seem to stitch them together, and (as I am apt to think) pass through
the very Bodies of the smallest of them, and quite through the whole Muscle
up the Cutaneous porosities; so that there is not one of these small
_ducts_, that run _per longitudinem_, but 'tis furnisht with a sufficient
number of outlets, when need requires, though too minute to suffer any
_alimentary_ juice to pass transversly (in a living Body) or any other
liquor, when the Body is dead and cold. But to wave their use at present,
and to return to what I was saying. Compress between the fingers this bit
of flesh, and you shall find the Juice, especially if the Meat be Hot, to
go before your fingers toward either end you please; but if you compress
both ends, you shall see it swell into the middle; and again, if you press
the middle, it will run out at both ends. But further, suppose a piece of
flesh, called _Parenchyma_, as big, or as little as you please, in any part
of the Body, and let me prick it with a Needle, where you shall appoint; if
you feel it, I presume you will acknowledge, a _Nerve_, or a _Fibrilla_,
related to it, is touch'd; If you feel it not, I am sure some liquor either
sanguineous or other, will follow the Needle; And from whence can that
come, but out of Vessels? unless {318} accidentally, as by a _Contusion_,
&c., it be extravased, in which case my Argument will not be injured,
because the part is depraved, whereas I speak of the parts, as they are in
their natural State.

To confirm and illustrate all which, I desire, that the following
_familiar_ Observations may be considered:

1. If a Horse, fat and fair to look on, without a hollow to be seen between
his Muscles, be rid extreme hard, and into a great sweat, and then kept one
day without water or moist meat, you shall see him took so thin in many
places as in the _musculous_ parts, that you will hardly believe it to be
the same
