The Anatomy 
though they are no thicker,than a fingle one might be made 5 yet ftand- 
ing at a diftance, have a greater ftrength than That could have. And 
the fame Architeóture, will have the fame ufe,in the Trunks of Plants; 
in moft whereof ‘tis very apparent; as for inftance, in Corm. For 
Nature defigning its sup a great Afcent 5 for its higher maturity, hath 
given ita tall Trurk.: But to prevent its ravenous defpoiling either of 
the Ear, or Soyl; although it be tall, yet are its fides but thin: And 
becaufe again, it fhould grow not only tall and thriftily, but for avoi- 
ding propping up, ftrongly too; therefore, the fame proportion as its 
heigth bears, to the thinnef of its fides, doth the greatneß of its Cir- 
cumference alfo ; being fo far dilated asto parallel a Quilt felf. 
25. $. Befides the pofition of the Ligvows Body within the compals 
of a Ring, there are fome Shootings thereof, often ftanding beyond 
the Circumference of the faid Ring, making fometimes a triangular, 
oftner a quadrangular Body of the Trunk. To the end, that the Ring, 
being but thin, and not felffufficient, theft, like Splinters to Bones, 
might add ftrength and ftability to it. 
26. $. Next, the fecurity and plenty of the sup. For fhould the 
Lignows Body, as it doth in the fmaller Parts of the Rost, ftand Central 
here alfo, and fo the Cortical wholly furround it: th 
the Sap would thus be more immediately exposd to tl 
and being lodged in a laxe Body, by them continually be prey'd upon, 
and as falt as füpplied to the Truk, be exhaufted. Whereas, the Pith 
ftanding in the Center,the sapthercin being not only molt remote from 
the Aer and Sun, but by the gargue, and efpecially the Wood, being 
alfo fürrounded and doubly immur’d, will very fecurely and copi- 
oufly be convey’d to all the Collateral Parts, and Ç as fhall be faid 
how ) thetop of the Trunk, 
27. $. And the Sup by the amplitude, and great porofity of the 
Pith, being herein more copious, its Fermentation alfo will be quicker 
which we fee in all Liquors,by ftanding in a greater quantity toge- 
ther, proceeds more kindly : And being tun'd ap within the Wood, 
is at the fame time not only fecur’d from lofs, but al i 
ons; the Day being thus, not too hot; nor the Night, too cold for 
it. 
28.5. And the Fermentation hereof being quicker, its motion 
alfo will be ftronger, and its Diftribution more effectual, not only to 
the dilatation of the Tra» , but likewife the fhooting out of the 
Branches. Whenceit is, that in the Bodies of Trees, the Ba of it 
RIF, though it be Sappy, and many Fibres of the Lignows Body mix- 
ed with it, yet feldom fendeth forth any ; and that in Herbs, thofe 
with the leaft Pith ( other advantages not fupplying this defedt ) have 
the feweft or fmalleft Branches, or other collateral Growths: and that 
Corn, which hath no Pith, hath neither any Branches. 
29. $. Laftly, the Advancement of the Sap will hence alfo be 
more ready and fufficient. For the underftanding where, and hi 
we fuppofe, That in all Truzks whatfoever there are two Parts joyntly 
hereunto fubfervient. In fome, the Ligwons Body and the Cortical, as 
in older Trunks 5 the Pith being either excluded, or dried : But in 
moft, principally, the Lignous Body and Pith 3 n moft Annual 
Growths of Trees ; but efpecially Herbs, where the Cortical Body is 
ufually much and often wholly Inferted.
