Against which I have now further to alledge, 1. That I observe in a piece of _Musculous_ flesh (so call'd) either raw, rosted, or boiled, &c. that if I so far extend it as to 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:
