{tance varies; {0 lels,in Parfnep, greater in Buglofs. They are commonly Tab. 7, 8. 
Re@tilinear, as in Lovage 3 but fomietimies Winding to and fro,\as in 
- a Carrot. Tab. 8. 
9. §. They are not always of one Size: in a Carrot near the 
Inner Edge of the Barque, exceeding Slender, and fearcely difcerna- 
ble 5, in others, Thicker, asin the Three greater ones of Melilot, and £: 
incommon Chersil. Both by their Diftance, and Size, they are alfo tN 
lefS or more Numerous 5 fome, only as they are nearer; fottie, as final- 
ler 5 others, asboth. And ‘tis proper, I think, to the Ltybous kind; 
either tohavenone, or but a few. Sometimes they are of the fame 
Thicknefs quite through the Barque from edge to edge, as in Murjh. Tab. 7: 
Mallow. And fometimes are confiderably {pread or dilated as they 
aproach the Skiz, wherewith they ate joyned, and whereinto they 
more vifibly run, as in Parfley, or the fmaller part of the Root of 
Lovage. And in fome Roots, as of Scorzonera, at fome times of the Tab. 8. 
year, when lefs fucculent, almoft the whole Parenchyma feems to be 
of the Nature of the Diametral Rays, in other Roots, The Bladders 
of thefe Diametral Portiovs, are fometimes, greater than thofe of the 
‘other Parenchymous Parts, asin Parfley,; and 1 think fometimes lefs. 
Yet as there, fo here, varioufly fizeds to about fix or eight De- 
grees and thofe of Parfley about the third, fourth, and fifth. Their 
Figure is Sometimes more oblong; arid their direction or refpett more 
towards the Center of the Root. ; . 
11. g. As the other Parenchymtous Parts of the Barque, are the 
Receptacles of Liquors fo thefe, (where they are) of Aé. This is ar- 
gued, From their being more White, and not Tranfparent, as fuch 
Roots and Parts ufe to be, which are more copioufly and equally fil- 
led up with Liquor: as the Pith of Elder, which, in the old Stalks, 18 
White 5 was once, and by being well foaked, will become, again 
Tranfparent. And from their being more dry and voyd of Liquor s 
whereupon their Bladders, which cannot be Vacuities, muft be filled 
with more or lefs Aer, mixed withthe Sap or the Vaporous parts thére- 
of. This is more obfervable in thofe Diametral Portions, which ter- 
tminate upon, and run into the Sk. 
12, §. THE BARQUE is not only of a divers Woof, but as ié 
faid, of a Compounded Subftance; there being a certain number of 
Lignous Veffels, fewer or more, in fome place or other, mixed with 
the Parenchymous Part above defcribed ; and fome way or other, are 
demonftrable in all Roots As by the Toughnefs of the Bargue, when 
pulled bythe length. By the vifible Continuation of the faid Vefels 
through the length of the Bargue, in the refemblance of {mall Threds. Tab. 6. 
And by the rifing up of the sap im the traverfé cut of the Roof, in 
fach places of the Bargue, where thefé Threds terminate: as the ex- 
iftence of the fame Vefelsin the Skinz, was proved in the Precedent 
Chapter. 
13. Thefe Tubulary Threds, tun not through the Bargue in di- 
rect lines ; but are frequently Braced together in the’ form of Net- 
Work; The Parenchymous Parts every where filling up the {paces be- 7,1, é. 
twixt the Braced Thredss as in Burnet, Scorzonera, &e. the Barque 
being paired or ftriped off, is apparent.
