Parfnep, greater in Bnglofs. They are commonly Zab. 7, $. 
but fometimes winding to and fro, as in

9. $. They are not always of one Size: in a Carrot near the 
Inner Edge of the Barque, exceeding Slender, and fcarcely difcerna- 
ble 5 in others, Thicker, asin the Three greater ones of Melilot, and 
incommon Chervil. Both by their Diftance, and Size, they are alfo 
les or more Numerous ; fome, only as they are nearer; fome, as final- 
ler 5 others, asboth. And 'tis proper, I think, to the Irsybous kind, 
either to havenone, or but a few. Sometimes they are of the fame 
Thickneß quite, through the Barque from edge to edge, as in Marfh- Tab, 7. 
Mallow. And fometimes are confiderably fpread or dilated as they 
aproach the Skiz, wherewith they are joyned, and whereinto they 
more vifibly run, as in Parfley, or the fmaller part of the Root of

pm grees; and thofè of Parfey about the third, fourth, and fifth. Their 
chfor Figure is Sometimes more oblong; and their direétion or refpeé more

11. $. As the other Parenchymons Parts of the Barque, are the 
diers, Receptacles of Ligwor; fo thefe, (where they are) of Aer. This is ar- 
à layo gued, From their being more White, and not Tranfparent, as fuch

whereupon their Bladders, which cannot be Vacuities, muft be filled 
with more or lef Aer, mixed with the Sap or the Vaporous parts there- 
of. This is more obfervable in thofe Diametral Portions, which ter- 
minate upon, and run into the Skin. 
12. $. THE BARQUE is not only of a divers woof, but as is 
faid, of a Compounded Subftance 5 there being a certain number of 
Lignous Vefels, fewer or more, in fome place or other, mixed with 
the Parenchymons Part above deferibed; and fome way or other, are 
emonftrable in all Roots As by the Toughnefs of the Barque, when 
pulled by the length. By the vilible Continuation of the faid Veffels 
through the length of the Barque, in the refemblance of {mall Threds, Tab. 6: 
And by the rifing up of the Sap in the traverfe cut of the Root, in 
lich places of the Barque, where thele Threds terminate: as the ex- 
iftence of the fame Pefelsia the Skin, was proved in the Precedent 
Chapter. 
13. Thefe Tubulary Threds, ran not through the Barque in di- 
reĝ lines 5 but are frequently Braced together in the form of Net- 
Work; The Parenchymons Parts every where filling up the {paces be-
