Of the WOOD. 
® HAT Portion of the Root which ftandeth next 
within the Barque, and in Trees, and Shrubby 
Plants, is the Wood 5 is alfo compounded of 
Two Subftantially different Bodies, Parenchy- 
mous and Lignous. The Parenchymous, is of 
es the fame Subftantial. Nature with that of the 
KENN RS Barque. And is originated from it 5 being not 
3 > only adjacent to it, but all round about conti- 
e nuous therewith; even as that, is with the 
Skins the Parenchyma of the Barque, being diftributed, from time to 
sino partly outward into the Ski», and partly inward, into the 
‘ood. 
2. $. The Pofition of the feveral parts hereof, is different. For the 
moft part it hath a Diametral Continuation, in feveral Portions, run- 
ning betwixt as many more of the Ligvous, from the Circumference 
towards the Center of the Root : all together, conftituting that, which 
in the Second Chapter of the Firft Wook, 1 call the Infertment. Inthe 
Roots of many Herbs, thefe Diametral or Inferted Portions are more 
obfervable, asin Cumfry ; which leadeth to the notice of them in all 
others, both of Herbs and Trees. Sometimes part of this Paren- 
chymous Body is difpofed into Rings,as in Fenil. The Number and Size 
of which Rings differ: In Fezil, when the Root is grown large, they 
are in fome places broader, but fewer in Beet they are narrower, but 
more. The Diametral Portions are here, in like manner, much va- 
ried; in Cumfry, Celandine, larger; in Beet, Buglofs, meaner; in Bo- 
rage, Parfuep, more, and finaller 3, and in molt Woody-Roots, ftream- 
ing betwixt the Pith and the Barque, as fo many {mall Rays. Their 
Continuation is alfo different ; in fome Roots, to the Centre, as in Co- 
Iumbine; in others not, as in Parjep. And fometimes different in the 
fame Root, as in the Vine. 
3. $. The Contexture of thefe Parenchymons Portions is fometimes 
Uniform, as in Buglofs, Peony; and fometimes alfo, as it is in the 
Barque , different; in part, more fappy , and tranfparent; in part, 
more white, dry, and aery, as in Carrot, Lovage, Scorzonera, and 
others; which yet cannot be ‘obferved without a wary view. But 
their general Texture is the fame being all made up of many fmall Blad- 
ders. Which are here of different Sizes, like thofe of the Barque, but 
for the molt part finaller. Their Shape likewife, is ufually Round 5 
but fometimes Oblong and Oval, asin Borage; or Oblong and Square, 
as in the Vine, 
4: $. The Lignons Part, ifnot always, yet ufally, is alfo'Com- 
panded of TwoKinds of Bodies, fèil. Succiferons or Lienousand Aer- 
Pefels. The Lignons as far as difcernable, are of the fame Confor- 
mation apd Nature with thofe of the Barque, and in the tranfverfe ec
