tion, which came Into my mind, of a piece of fine Cloth (which confifU 
of fo many feveral minute Hairs, call'd Wool) was no difcouragemenc to 
this opinion* Yet I durft not be prefumptuous as to indulge my felf too 
much in it • much lefs to venter prefently to fpeak of a thing, which feerrf d 
to contradid fo many Learned Men’s belief. But being relllefs, till I might 
receive more fatisfaftion inthe thing, I iterated experiments over and over * 
fome of which prov’d fo fuccefiful to my apprehenfion, that S* was encou- 
raged in the year 1663* and 1664. t0 dikourfe of it to feveral very worthy 
Perfons, as Mr. Bojk Sir william petty f Dr williams, Dr. Lenthal, I)r, 
fafpar Ntedham,Dr.Samfo»,(vjho aftei wards lent me a Letter from France , 
intimating the acquaintance he had made with the Learned Steno, who hath 
fince published fomethingof the fame DifcoyeryJ Mr. Daniel Cox, and Dr 
Samuel Parker , &c, who doubtlefs cannot but remember, that then I re- 
lated to them, 1 found much caufe to believe, that that fubftance commonly 
call’d fartnchjma, was in moft,if not in all its Parenibjmsus parts, full of 
Veffels-, however it had been imagin’d by all, l could ever meet with, to 
confift in great part of a fubftance, in many places void of Veffels, defigned 
for fuch ufes, as are above mentioned. 
Againft which I have now further to alledge,! .That I obfer ve in a piece cf 
Mu/culotts Flcfh (fo call’d)either raw, rolled, or boiled, e.that if 1 fo far ex* 
tend it, as to make it to be feen through, 1 can(afsifting my Eye) perceive it full 
of Veffels placed as thick as is pofsible to be imagin’dfthe fat if there be any 
being firft removed)there appearing then nothing but vefTels.yet fo as with a 
Microfcope may be feen through, when they are extended, 2.That,ifany one, 
as he is at dinner, take a piece of flefh, and begin either at the head or tail 
of a M.u[cle,\\e may divide it in infinitum, all along from head to tail, 
without breaking any thing of thar, called Flefti,oniy thefe tranfverfe Fibres 
that feem to flitch them together, and (as I am apt to think ) pafs through 
the very Bodies of the fmalleft of them, and quite through the whole Mufde 
up the Cutaneous porofities • fo that there is not one of thefe frnail ducts, 
that run per Im^itudinera, but ’tis furnifhtwith a fufficient number of outl 
lets, when need requires, though too minute to fuffer any alimentary juice 
to pafs tranfverfly (in a living Body) or any other liquor, when the Body 
is dead and cold* But to wave their ufe at prefent, and to return to what I 
was faying, Comprefs between the fingers this bit of flefh, and you fhall 
find the Juice, efpeciaily if the Meat be Mot, to go before your fingers to- 
ward either end you pieafe ^ butif you comprefs both ends, you (hall fee it 
fwell into the middle • and again, if you prefs the middle, it wrll run out at 
both ends. But further, fuppofe a piece of fidh, called Parenchjma, as 
big, or as little as you pieafe, in any part of the Body, and let me prick 
it with a Needle, where you (hall appoint ; if you fed it, I prefume you 
will acknowledge, a Nerve, or a Fihilla,rt\ned to it, is touch’d 2 If you 
feel it not, I am fure fome liquor either fanguineous or other, will follow 
the Needle .* And from whence can that come, but out of Vcffeis ? uniefs
