Argument will not beinjured, becaufe the part is depraved, whereas! 
fpeak of the pans, as they are in their natural State. 
To confirm and illuftrate all which, l de fire, that the folio mngfamiliar 
Obfervations may be gonfidered • 
1 . If a Horfe, fat and fair to look on, without a hollow to be feen be- 
tween his Mufcles,be rid extreme hard, and into a great fweat, and then 
kept one day without water or moift meat, you fliall fee him look fo thin in 
many places as in the mufcstlous parts, that you will hardly believe it to be 
the fame Horfe, efpecially if he be ( as thephrafeis among Horfe-mafters ) 
a Na-Jh or Wafh~ Horfe . The caufe of, which thinnefs will eafily be granted t© 
be only an exhauftion of Juice, expended oat of the BloodjWhich did fluff 
oat thefe Veffels* And whoever, that is ufed to ride hard, (ball obferve, 
how thick this fold Horfe breaths, and at what a rate he will reek and fweat, 
will not much wonder at the alteration* But if the Horfe be a hardy one, 
and ufed to be hard ridden, then you will fee, that one days reft, and his 
belly full of good meat and drink, will in one day or two almoft reftore 
him to his former plight, the food being within thatfhort fpaceof timefo 
diftributed, that all the Veffels will be replenifhM again, as before. And 
the cleaner the Horfe is, the fooner recruited, and the lefs fign of hard ri- 
ding will appear* This feems to (hew' the facility, with which the Juice, 
called Blood, pafleth • Which furely, if there were fuchathing as a pa- 
rexehyma, might by feveral accidents ( not difficult to mention ) be fo de- 
prav'd in feveral parts of it, that it might lofe its receptive faculty v than 
which it may be thought to have none of greater ufe, being fuppofed to be 
without Veffels. 
2 . Difcourfing foraetimes with Grafters in the Country, about the Pafture 
of Cattle, i have been informed by them, that, if they buy any Old Beafts, 
Oxen, or Cows, to feed, they chcofe rather thofe that are as poor,as can be,fo 
they be found ., becaufe that, if they are pretty well in flefii, what they 
then add to them by a good pafture, though it make them both look and fell 
well, yet it will not make them eat fo well, their flefh proving hard and 
very tough ; Which fome may fuppofe to be the age of Parenchyma - and fo 
it is of that fo called. But if thofe Beafts be old and extremely poor, then 
they feed very kindly, and will be not only very fat,butfpend well, like 
young ones, and eat very tender* 
Of which 1 take the reafon (excluding a Parenchyma now ) to be this* 
When an Oxe ora Cow is grown old, and in an indifferent plight as to his 
flefh (for fo it is call’d ) all thofe Feffels having been kept at that fize for 
the moft part, have contraded a tenfenefs and firmnefs, and their fibers lefs 
cxtenfive, not fo fitted for the reception of more un&uous particles ro relaxe 
them .• and that additional un&uous matter, which occafions fatnefs,is forced 
to feek new quarter , any where ( often remote from Mufcies ) where it can 
fee with leaft difficulty reeeivedi fometimes to one place, fometiraes to ano- 
ther
