55. §. If the Parenchymous Parts have much the greateft, the 
Root feldom liveth beyond Two Years; but afterwards perifheth ei- 
ther in whole, or in part; as do divers bulbous, tuberous, and other 
Roots; whether they are more Porous and Succulent, or more Clofe 
and Dry. If Porous, all the Liquid Principles ftanding herein more 
abundant, either by a ftronger Fermentation, or otherwife, Refolve 
the fixed ones of the Organical Parts; whence the whole Root, rots 5 
as in Potatos, So alfo Parfueps, and fome other Roots, which, in a 
hard and barren soz/, will live feveral years, in another more rank, 
will quickly rot. Ifthe Parezchywa be Clofé, then the Aer, chiefly, 
entring in and filling it up,thus mortifies the Roots not by Rotting the 
Parts, but over Drying them; asin Satyrion, Rape-Crowfoot, Monks-

Som ay & "56. §. But if the Aer-Veffels have the greateft Proportion, and efpe- 
a as cially if they are more Jarge, and withall, are fpread more abroad : 
ihe the Root is Axnual, as in Thorn-Apple, Nicotian, Carduus Ben. &c. 
are And of the fame Kindred, if any, thofe are Azaual, which have the 
moft Aer-Vefféls. So Endive and Sonchus, which have ftore of 
Aer-Veffels, are both Annual: whereas Cichory, in which they are few- 
er, isa Perennial Root. For hereby a more copious Aer being Tran& 
(b)P. 2, §, fuled into all the other Parts ; (6) they are thus, by degrees, hard- 
25,26. ned, andbecome fticky ; and fo impervious to the Sap, which ought 
to have a free and univerfal Tranfition from Part to Part. As Bones, 
by Precipitations from the Blood, at length, ceafe to grow. Or the 
fame more abundant Aer, fo far volatilizeth the Liquors in the Root, 
that they are wholly advanced into the Truk , and fo the Root is 
flarved. Whence alfo the Aer-Vefféls of the Trunk; where they ave 
numerous, and over proportioned to the Bulk of the Root, as in Corn; 
they fo far promote the advance of the sap, as to exhauft the Root, 
fucking it into a Confumption and Death. 













































How tlic 57. § FROM THE Prizciples of the Parts, their Contents and 
Contents of the feveral Qualities hereof are alfo various; (c) the Fluid of each 
the feveral Organical Part, being made, chiefly, by Filtration through the fides 
Parts are thereof 5 fuch of the Principles in the Sup, being admitted into, and

of the Guts, into the Laéeal Veffels: or as Water in Purgations, is 
{trained through the Glands of the fame Gufs, from the Mejénte- 
vical, 
58: §. The Principles therefore of the Parenchymous Fibres being 
JSpirituows, acid, and aerial, they will alfo admit the like into them; 
excluding thofe chiefly which are AlAalize and Oleouvs. (d}) And as by 
the Conjugation of fuch Principles in the Fibres, the like are capable of 
admittance into their Body : fo the Proportioz and Uxion of the fame 
Principles, regulates the tranfmiffioz hereofinto their Concave. Where- 
fore, the predominant Principles of the Fibres being chiefly acid, next 
fpirituous, and aery » the more aery ones will be tranfiitted. For if 
more of them fhould fix they muftdo fe by fimi#itude and adhefion: 
But where there are fewer fimilary parts to adhert to, fewer muft ad- 
_ here. The Fébres therefore contain fo many parts of Aer, as to admit 
many
