14. §. They feem, at firft, where they are Braced, to be Inof- 
culated 5 foas to be perviousone into another. But a more accurate 
view,efpecially affitted by aMz/crofcope,difcovers the contrary. Neither 
are they woun’d any way one about another, as Fhreds are in a Rope: 
nor Implicated, as in ravied Yarn, or the Knots of a Net: but only 
contiguous or fimply Tangent, as the feveral Chords in the Braces of 
a Drum : being thus joyned together by the Parenchymous Parts, asin 
fpeaking of the Pith, will be underftood how. Yet do not always the 
fame Threds belong and keep entire to one Brace 5 but are freqnently 
parted into lefler Threds; which are tranfpofed from Brace to Brace. 
Nor do they always, in whole or in part, prefently after their contin- 
gence, mutually fall off again; but, oftentimes, run along collateral- 
Ty joyned together for fome fpace. 
15. §. Thefe Braces are of various number in divers Roots ; more 
frequent in fernfalem Artichoke, \efs in Scorzonera, more rare in Cumfry, 
The Threds likewife are varioufly Divaricated 5 fometimes more, where 
the Braces are frequent, as in. Ferufalem Artichoke 5 and fometimes lefs, 
where the Braces are rare, as in Scorzovera, Dandelion: And in all 
Roots, more frequent towards the Inner Verge of the Bark. 
16. §. By what is faid, it is partly implied, That thefe TAreds, are 
not Single Veféls; but a Clufter of them, Twenty, Thirty, or more or 
fewer of them together. Yet as the Threds are not Inofculated in the 
Braces 3 fo neither are the Vefels, in the Threds. Nor yet Twifted ; 
but only ftand collateral together 5 as the feveral Single Threds of the 
Silkworm, do in Sleave-Silk. Neither are thefe Vefels pyramidal, fo far 
as the Glas will difcover; or, from probable Reafon, may be conjec- 
tured. Nor Ramified, fo as to be fucceflively propagated one from 
another, after the manner of the Veins in Animals: but Cylindrical , 
and Diftin@ly continued, throughout the length of the Root ; as the 
Several. Fibres in.a Tendon or Nerve. 

17. §.. THESE VESSELS are either themfelves of divers kinds, or 
ferve, at leaft, to conftitute divers Kinds, in divers Roots: of the dif- 
ferent Natures whereof, although there may be other ways whereby to 
judge 5 yet fo far as by Infpection, we may do it, chiefly, by the Di- 
verfity of thofe Liquors, which they feverally contain. Sometimes they 
yield a Lympha; and that Thin, as they do ina Parfweps efpecially 
thofe that make a Rizg, at the inward extremity of the Bark. See the 
Root it felf That this Clear Szp afcendeth only from thefe Veffels, is 
certain. Becaufe no Liquor will do the like, from any Parenchymous 
Part, asChap. 2. hath been faid. And becaufé it is ofa different 
nature from the zp contained in the Bladders of the Parenchyma 3 al- 
though of the fame Colour, yet fenfibly more Sweet. 
18. § Sometimes they yield a Thick and Mucilaginous Lympha, as 
in Cumfry, as appeareth by its tenacity. From the Mucilaginous Con- 
tent of thefe Veffelsit is, I fuppofe, that the sap contained in the Blad- 
ders isrendred ofthe like nature, fo far'as it approaches hereto , which 
fometimes ismore, as in Marfh-mallom ; and fometimes but little as in 
Borage ; For in prefling out the Liquor of this Plant, and then heating 
it over an indifferent fire; thefar greater part hereof remaineth thin 5 
only fome certain {trings and little bits ofa gellied fubftance are mixed 
herewith; which asit f{eems, were originally the proper Liquor of thefe 
Muciducts. 19. $.
