the Pith is not only of the fame fubftantial nature, and by the In- 
Jertions doth communicate with the Barques and that it is alfo aug- 
mented by it; which is true of the Pith of all Roots; but is moreo- 
ver, by mediation of the {aid Infertions, wholly originated from it 5 
that isto fay, from the Parenchymous Part thereof. ‘The various appea- 
rances of the Infertions and Pith from the filamentous Parts to the 
Tab, 2. f.9, top of the Root, fee in Tab. 2. The Pores of the Lignous Body, as 
it ftands entire in the faid filamentous Parts, are beft feen when they 
have lain by a night todry,after cutting. ; 
18. ¢. A farther evidence hereof are the Proportions betwixt the 
Cortical Body and Pith, For as about the inferiour Parts of the Root, 
where the Pith is {mall, the Cortical Body is proportionably great ; fo 
about the top, wherethe Pith is enlarged, the Cortical Body(now more 
properly becoming a Barque) groweth proportionably lefs, /c. becaufe 
the Infertions do ftill more and more enlarge the Pith. Likewife the 
peculiar frame of fome Roots, wherein befides the Pith, the Lignons 
Body being divided into two or more Rigs, there are alfo one or more 
thick Rings, ofa white and {oft fubftance;. which ftand betwixt them 5 
and are nothing elfe but the Infertions of the Cortical Body collected 
into the faid Rizgs; but, towards the top of the Root, being inferted 
again,thus make a large and ample P7th 3 asin older Fennel-Roots,thofe 
Tab2.f.8. of Beet, Turnep, and {ome other Herbs, is feen. 
19. §. The Pores of the Pith, as thofe of the Cortical Body, are 
extended both by the breadth andlength of the Root, much alike; yet 
are they more or lefs of a greater fize than thofe of the Cortical 
Body. 
20. §. The Proportions of the Pith, are various; in Trees, but 
fmall ; in Herbs, generally, very fair; in fome making by far the great- 
eft part of the Root; asin a Turnep: By reafon of the wide circum- 
ference whereof, and fo the finer Concogtion and Affimilation of its 
Sap 5 that Part which in moft old Trunksis adry and harfh Pith, here 
proves a tender, pleafant meat. 
21. g. Inthe Roots of very many Plants, as Turneps, Carrots, Gre. 
the Liguous Body, befides its main utmoft Rizg, hath divers of its of- 
culated Fibres difperfed throughout the Body of the Pith; fometimes 
all alike, and fometimes more efpecially in, or near, its Centers; which 
Filves, as they run towards the top of the Root, ftill declining the 
Center, at laft collaterally ftrike into its Circumference; either all of 
them, or fome few, keeping the Center ftill. Ofthefe principally,the 
Succulent part of the Ligwous Body of the Truk is often originated. 
22. §. Some of thefe Pith-Fibres, although they are fo exceeding 
flender, yet in fome Roots, asin that of Flower de liz, they are vifibly 
concave, each of them, in their feveral Cavities alfo embofoming a ve- 
ry fmall Pith; the fight whereof, the Root being cut traverfe, and laid 
in a Window for a day or two todry, may without Glafes be obtain’d. 
And this is the general account of the Root 5 thedeclaration of the man- 
nerof its growth, with the uf and fervice of its {everal Parts, we fhall 
next endeavour. 
23. g. I SAY THEN, That the Radicle being impregnate, and 
An Account (hot into the Moulds, the contiguous moifture, by the Cortical Body,be- 
of the ing a Body laxe and Spongy, is eafily admitted : Yet not all indifcrimi- 
Growth of oil es c 
he ‘ nately, but that which is more adapted to pafs through the sana a 
vuticle.
