Book IV. of dievad 155 ‘ 
14. §. In Borage, and Moth-Mullen, they ftand alfo in Five Par- 
eels. Inthe former, the largeft maketh ftill amore bulky Arch; than Tab. 49. 
that of Clary 5 being thicker, as broad, and of a lefler Circle or more 
bowed. But in MuWeiz, it maketh almoft an entire Oval: i 
15. §. By means ofthis Figwration, a fufficient number of Veffels 
for fuch large Leaves, are not only more conveniently Diftributed into 
them 5 but alfoftand more fafely in the stalk. For were the Arch con- 
tracted into a folid Cylinder, it could not fo prefently be refolved into 
fmall Fibers. And were it laid into a flat Plate, or {traight out, either 
the Figure of the stalk, and fo of the Leaf, muft be altered; or elfé, the 
two ends of the Plate, would come too near the Circumference of the 
Stalk, and fobe more liable to the Impreffions of the Weather : as may 
be obferved in cutting the Stal/f tranfverfly, and by the Figures. 
16. §. IN the Body of the Leaf, befides,the Pofitions of the Fibrois 
Strings or Thredss above expefled, there is one Thred, bigger or lefs, 
which in all Plats, runs round the Edge of the Leaf,and hems in all the 
refts but can hardly be well obferved in any, without {tripping off the 
Skin of the Leaf: When the Fibres of the Leaf, are bigger,or lefs tender, Tab, 50. 
asin Holly , the skiz and the Pulp are fometimes found either rotted 
off, or eaten away with Infects; whereby, both the faid furrounding 
Fiber, and the reft, are all very fairly vifible. 
17. §. THE Veffls feem tobe continu’d, in the Leaf, by being 
Ramified out of Greater into Lefs, as Veins or Arteries arein Axiséls. 
Butif the Shiv and Pulp of the Leaf, as fuppofe a Borage-Leaf be taken 
off, and the Veffels laid bare 5 by the help of a good Gia/, it will ap- 
pear 5 That they areall ofthe fame Size, every where in the Leaf; Tab. 50; 
and alfo continued throughout the fame, all feveral and diftin& Pipes one 
from another, as the Threds ina Skein of Silk, And that therefore the 
Diftiibution of the Threds which the Vefels compofe, is not the Raimify- 
ing of Greater Pipes into Lef$ 5 but the dividing a greater Clufter of 
Pipes, into feveral lefler Clufters, till at laft they come to be fingle 5 as 
in the Diftribution of the Nerves. 
18. §. The Vefels feem alfo to be Inofeulated, not only fide to 
fide, but the énds of fome into the Sides of others. But neither is 
this ever really done : the lefler Threds, being only fo far diduéted, as Tb. 50: 
fometimes to ftand at Right- Angles with the greater. So that they are 
fnofculated only End to End or Mouth to Mouth, after they are come 
at Jaft to their final diftribution. 
19. §. The Aer-Veffels, are not only, as is faid, Exiftent in the 
Leaves of all Plants; but are herein alfo difcoverable without the kelp 
of Glafes: For wpon breaking the stalk or chief Fibers of a Leaf’; the 
likenefs of a fine Woolly Subftance, or rather of curious {mall Cobwebs, 
may be feen to hang at both the broken Ends. This is taken notice of, 
only in fome few Plants, asin Scabious, where it is more vifible. But 
may alfo be feen more or lef, in moft other Plants, if the Leaves be ve- £4.51, @ 
ry tenderly broken: as I have noted near twenty years finces and 52+ 
* thence conjectur'd them a Sort of Veffel common to Plazts. Now this 
fine Wool, is really a Skein of Aer-Vefféls, or rather of the Fibers of the 
Aer-Veffels, unroaved from their Spiral Pofition, and fo drawn out in 
Length. As they appear thus unroaved and drawn out at Length, both 
to the bare Eye, and through a good Microfcope, I have reprefented in 
two Exemples, the one a Scabions gi the other that of a Vive.
