Of the PITH. 
BATHIN the Lignous Part lyeth the Pith. This 
Part is not common to all Roots; for fome have 
none, as Nicotiaw, Srtamoninm, and others. Yet 
many which have none, or but little, throughout 
all their lower parts, have one fair enough about 
their tops, as Mallow, Bourage, Dandelion, and 
id the like. See the Roots. And in many others there 
are Parenchymous Parts, of the fame fubftantial nature with the Pith, 
diftributed betwixt the feveral Rings of Veffels, and every where vi- 
fible, from the top tc the bottom, asin Beet, Fevil, &c, Tab. 8. 
2. §. The Size of the P7th is varied by many Degrees, eafily rec- 
koned an Hundred; in Fewil, Dandelion, Afparagus, but {mall ; in 
Horfe-Radifh, Valerian, Biftort, great. The Shape hereof, in the 
lower parts of moft Roots, is Pyramidal ; but at the tops, Various, ac- 
cording to the different Diftribution of the Vefels, asin Carrot, Ayper- 745, 6, 
bolick, in Parfley, Oval as appeareth, in cutting the Roots lenght- 
ways.

3. §. The Pith, for the moft part,efpecially in Trees, is a Simple Body : 
but fometimes, it is, asthe Bargue, compounded ; fome certain number 
of Succiferous Vefféls being mixed herewith 5 as in Ferufaleme Artichoke, 
Horfe-Radifh, &c. wpon a traverfe cut, by a ftritt view, may be 
difcerned. Their Pofition is fometimes Confufed, as in aGarrot 5 and 
fometimes Regular, asin Parfley; appearing, by the traverfe cut, in 7, 6, 
Rings, and in cutting by the length, in Arches. And fometimes the 
Pith is hollow; as inthe Level-Roots of Bifhops-Weed: thefe Roots 
being made out of the Stalk, as in the Fari# Chapter hath been fhew- §. 13,14,13.

Tab. 6, & 8. 
4. §. As allthe other Partsof the Roof, are originated from the 
Seed , {o, fometimes, is the Pzth it felf. But fometimes, it hath its 
more immediate Derivation from the Bargue. Hence it is, that many 
Roots, which have no Pith in their lower parts, have one at their 
top, as Columbine, Lovage, &c. -For the Parenchymous Parts of the 7,), he 
Barque being, by degrees, diftributed into Diametral Portiozs, run- 
ning betwixt thofe of the Ligvous Body, and at length, meeting and 
uniting in the Centre, they thus conftitute the Prth. In the fame 
manner, at the top of fome Roots, the Pithis either made or augmen- 
ted, out of the Parenchymous Rings above defcribed; thefe being 
gradually diftributed to, and embodied in the Centre 5 asin Fev#l, and 
fome other Reots, their lower and upper parts compared together, 
may be feen. Even asin Aximals, one Part, as the Dura Mater, is 
the original of divers others.
