16. §. Theentrance of this Impregnaté Water or Sap is not with- 
out difference, but by the Regulation of the intervening shiz; being 
thereby ffraived and rendred move pure : the. Skiz, according to the 
thicknefs (2) or clofenefs thereof, becoming fometimes only asa brown _ 
paper, fometimes as a Cotton, and fometimes as a Bag of Leather to (4) es 
the tranfient Sap, asthe nature of it doth require. By which it is ale" * 
fo moderated, \elt the Barque, being fpongy, fhould fuck it up too faft; 
and fo the Root fhould be, as it were, furcharged by a Plethora. And 
divers ofthe succiferous Veffels being mixed herewith (4) and lying 
next the Soil, ufually more or lefs wortified, and fo their Principles Cb) Putc2. 
fomewhat refolued; the Sap is hereby better ppecified, and further So 4. 
tindtured 3 {uch parts of the Sap beft entring, as are moft agreeable to 
thofe Priaciples 5 which the Sap alfo carries off, in fome part; as it 
paffeth into the Barque. 
17. §. The Sap thus ferained, though it be pure, and confifteth of 
Effential parts; yet being compounded of heterogeneous ones$ and re- 
ceived into the Parenchyma of the Barque a laxe and {pongy Body, they 
will now eafily and mildly ferment. Whereby they will be yet fur- 
ther prepared, and fo more eafily infinuate themfelves into all the 
Bladders of the faid Parenchyma 5 {welling and dilating it as far as the 
Coxtinuity of its partswill bear. Whereupon, partly from the conti- 
nued entrance of frefh sap, and partly by a Motion or Preffure of Re- 
fitution inthe fwollen and Tenfed Bladders of the Parewchyma, the 
Sap is forced thence into the other parts of the Root. 
18. §. And becaufe the Parexchyma isin no place openly and 
Vifibly Pervious, but is every where compofed of an Infinite Number 
of fmall Bladders (c); the Sap, therefore,is not only fermented therein, 
and fitted for Separation; but, asit pafleth through it, isevery part (2) P-t. 3: 
of it, f2rained an Hundred times over, from Bladder to Bladder, $44 
19. §. The Sap thus fermented, and firained, is diftributed to the 
other Orgawical Parts, according as the feveral Prizciples of This, are 
agreeable to thofe whereof the faid Organical Parts confift. As the Sap 
therefore paffeth from Bladder to Bladder, fuch Principles as are agree- 
able to thofe of the Frbres of the faid Bladders, willadhere to, and in- 
finuate themfelves into the Body of the Fibres 5 fe. Watry chiefly, 
next Acid, then fpirituous, Earthy, Aery, and Oleous. (d) (d) Idea, $3 
20. §. And the Sap by its continual appulfe and percoletion, as it 50,52. 
leaveth fome parts upon the faid Fibres 5 fo as it is /queezed betwixt 
them from Bladder to Bladder, it licks and carries off fome others from 
them, in fome wziox together with it 5 and fo is Impregwate herewith: 
as Water, by pafling through a MizeralVein, becomes tinétured with 
that Mineral. 
21. §. The Sap thus Impregnate with fome uxited Principles of the 
Parenchymous Fibres, paffeth on to the Lignous Veffels, whereinto their 
correfpondent Prizciples alfo enter 5 fc. Watry,Saline, Oleows and Earthy 
chiefly. (e) And becaufe the Parenchymous Principles mixed with (e.) Teas $: 
them, are in fome degree wzited, and fo more, ready to fix fome of 51, 52. 
thefe therefore will likewife enter into the faid Vefels. Whereupon,the 
Alkali oleofum of the one,and the Acidum fpiritnofum of the other,meeting 
together 5 Thefe, with the other Priwciples, all concentre, and of 
divers fluids, become one fixed Body,and are gradually agglutinated to 
the Vefels 5 that is, The Veffels are now nourifhed.
