many more into their Body ; but not to fx them; which therefore 
mutt needs, upon admiffion, pafs through into their Concave; where, 
together with fome other more fpiritwoas parts, they make an Atherial 
Fluid. And becaufe fome aqueous or vaporous parts will alfo (train 
through with them 5 hence it 1s, that as more and more of thefe enter, 
they by degrees (till thru(t out the aery ones 5 which quitting the more 
Succulent Fibres of the Parenchyma, are forced to betake themfelves 
to the dryer ones, feil. all thofe, whereof the Diametral Portions do 
confit. For. the fame reafon the Aery parts being gradually excluded 
the fücenlent Fibres of the Barque; they are forced to recede and tranf- 
migrate into thofe ofthe Pith, Andthe Fibres of the Pith themfelves 
being filled, aud the Aery parts (till forced into them; they at length 
alfo {train through the Fibrés into the Bladders : whense it comes to 
país, that while the Barque is fucculent, the Pithis often times filled 
with Aer.

aqueous, will both admit and copioufly fix the like Principles, as their 
proper Aliment, The Water being more perfluent than the reft, will 
therefore ftrain, with a lighter Timifnre of them, into. their Concave, 
Efpecially the Oleous parts of thefe being rampant, and leapt to fix and 
Jéize the aqueous, upon their entrance, than the faline.

Conftipation of the Parenchymous Parts all round about their Sides 5 
the Liquor conteined in thofe Parts, although it may cafily enough 
be transfufed into the Hollow of thefe Veffels ; yet feems it not, with 
equal facility, to be refunded thence: So that the thinner and more 
aqueous Portion only, pafíing off; the remainder, is, as it were, an 
Oleous Elixyr, or extraét, in the form of a Milk,

part, dependent on the Principles of thofe Veféls, being in their per- 
colation tinéured therewith. But becaule the percolation is not made 
through the Body of the Fibres whereof the Veffels are compofed, but 
only betwixt them; therefore the tranfient Principles more promifeuof-

the Proportion and Situation of the Parts, whereby the faid Contents 
are with different Facility and Quantity, communicated one toanother. 
Hence it is, partly, that a Vine, or that Corn, hath fo little Oyl: fe. 
Becaufe their Aer-Vejfels, in proportion with the other Parts, are fo 
Great and Numerous: in Corn, the Stalk. being alfo very hollow, and fo 
becoming as it were, one Great Aer-Veffel. For the Oily parts of the sap, 
are fo exceedingly attenuated (c) by the Aery Ferment contained in 
thefe Vefélss that they are, for the moft part, fo far ¿mmer/ed in the 
Spirit, or mixed therewith, asnot, by being collected in any confide- 
rable Body, to be diftinguifhable from it. “And the affinity that is be- 
twixt Spirits and Oils, efpecially Efential, is manifeft : Both are very
