of the Root, do oftentimes, as thofe, emit a Liguow. They are alfo 
Braced 5 and many of them run in diftinét Threds or Portions, collate- 
j rally together. q 
5. $. The Aer Veffels I fo call, becaufe they contain no Liquor, bnt 
an Aery Vapour. They are, more or lefs, vifible in all Roots. They may 
be diftinguifhed, to the bare Eye, fromthe Parenchymons Parts, by their 
Whiter Surface; and their ftanding more prominent, wheras thofe 
fhrink below the tranfverfe level of the Root, upon drying. They are 
frequently Conjugated divers of them together , fometimes fewer, and Tab. 10, 
for the moft part fingle, as in A/paragus 3 fometimes many, as in Horf & 15. 
Sl kada. And their Conjugations are alio Braced, as the Threds of tLe 
Md Succifirous Veffls. But they are no where Inofeulated : nor Twilted 
areny, one aboutanother 5 but only Tangent or Collateral. Neither are they 
4 ito Ramified, the greater into lefi 5 but are all diftin@ly continued, as 
OF the the Nerves in Animals, from one end of the Root to the other. 
Mg not 6. $. Their Braces, as thofe of the Succiferons Vefféls, are alfo of 
conti» various number: in Jerufalem Artichoke, Curfry, Scorzonera, more rare 5 
mh the in Borage, Burnet, more frequent 5 as by {tripping off the Barque of 
time to fuch Roots, where it is eafily feparable, may be feen. And they often Tab. 6. 
nto the vary in the fame Root; fo in Borage, Scorzonera, &c. theyare more 
frequent in the Centre, and next the Barque, than in the Intermediate 
Por the fpace, as by fplitting thofe Roots down the middle doth appear. They 7, 
Ss, ru alfo vary from thofè of the Sueciferons Vefels 5 thofe being ufually more 7" % 
ference frequent, as in Jernfaler Artichoke, than thefe of the Aerial. 
which 7. $. Betwixt thefe Braced Aer-Veffels, and the reft, which make 
Inthe the true Wood, run the Parenchymous Parts above defcribed 5 as they Tab. 6. 
eu do betwixt the Succiferons in the Barque : and fo make up two Pieces 
and of Net Work, wherof one is the filling up of the other. 
Pest 8. $. The Pofition ofboth thefe Kinds of Veféls, is Various. The 
id Size Sueciferonsor Lignous ‚are fometimes pofited in diametral lines or porti- > 
they ons 5 as in the Vine, and molt Trees. Sometimes, oppofitely to the 24-17: 
A Aerial, asin Beet 5 each Ring herein being double, and made both of Ta}, 8, 
8 Sap-and Aer-Vefels. 
Gm 9. $. In Nettle the Pofition isvery peculiar, from what it is in the 745,8; 
ka Roots of other Herbs 3 being curiously mixed 5 the Succiferous running 
Their eroß the Aerial, in feveral, viz. Five, Six, Seven, or more Rings, 
into In Bryony the feveral Conjugations of the Aerial, are diftinGly fur- 
inthe  TO2nded with the Succiferous. In Patience, the Succiferous are dilpofed, Tal 7: 
befides Rays, into many fmall Rings, of different Sizes, (prinkled up 
and down, and not, as inother Roots having one common Centre 5 
within divers whereof, the Aer-Vofféls are included : efpecially within 
thofe which are drawn, not into Rings, but, as it were, into little 
ftragling Hedges. 
„10. $. That alfo of the 4er-Vefels, is Various and Elegant : efpe- 
cially in the upper part of the Roof. In Ammi, Lilium-non-bulbofom, 
they make a Ring. In thefe, a Prick'd-Ring 5 in Peony, a Ring of 
Rays in Valerian, a Ring of Pricks and Rays. In others, they make Tab. 7,83 9. 
not Rings, but longer Rays, extended either towards the Centre, 
as in Scorzenera 5 or meeting in it, as in Columbine, In the Common 
Dock, they ftand more in fingle Rays: in the other Species of Docks, 
both in Rays, and collateral Conjugations between.
