tations of thee Seecl , becoines the Root ; tlie 

 oiher, the Plume, which bekoms the Trunk of 

 the Plants, and being divided it its

loose end into divers pieces, (all very dose set 

 together as Feathers in a bimch) these pieces are 

 so many true and already fonnid though not 

 displayed, Leaves, ititended for tlie saiil Trunk,, 

 and foulded up in the same plicature, whereir 

 upon the Beans spronting, the do appear. These 

 Organical parts he finds composed of these Si- 

 milar ones, viz. 1. the Cuticle, extending itself 

 over the whole Bean , and herein distinguisht 

 from the Coats, that whereas these, upon setting 

 the Bean, do only adininister the sap, and then 

 die; the Cuticle is with the Organical parts of 

 the Bean nourish't, augmented, and coextended. 



2. The Parenchyina it seif, having soine simi- 

 litude to the pith, while sappy, in the roots and 

 trunks of plants; common to, and the same in, 

 the Lobes, Radicle and Plume of the Bean. 



3. The Inner -Body, distributed troughout the 

 parenchyina, but withall essentiälly differenf from 

 it; called by the Autlior the Seminal Root, and 

 distinguisht from tlie Radicle , in that the for- 

 mer is the Original root within its seed, the 

 latler is the Plant-root, which the Radicle be- 

 coms in its growth; the parenchyina of the seed 

 being, in some resemblance, that to the Semi- 

 nal root at first, which the mould is to the 

 Plant-root aftenvards; and ihe Seminal root 

 being that to the Plant-root, -vrhich the Plant- 

 root is to the Trunk. Having viewed these 

 parts, he inquireth into tlieir Use, and in what 

 manner they are the Fbuntain of Vegetatior, 

 and concurrent to ihe Being of the fir.ure Plant. 



Proceeding to the Root, (which he finds 

 substantially one with the Radicle, as are the 

 Parts of an Oldman with those of a Foetus,) 

 be therein observeth ils Skin, Cortical Body, 

 and Liguous part, together with the Original of 

 each of these; and tlie Pores of the two lalter, 

 and their proportions; as also the Pith, and its 

 Original , sometimes from the Seed , sjinetimes 

 from the Coriical Body, together with its Pores, 

 and Proportions: More-over, the Fibres of the 

 Lignous body dispersed trougli the pith, and 

 the Cavity and Pith of those Fibres. Wliere 

 he explaius, How the Root grows, and what is 

 the Use of its parts; how it grows in length 

 and breadth ; and how it descends ; adding the 

 Use of the Pith, viz. for the bei. er advance- 



merits of the Sap, and its quieket and higher, 

 Fermentation, begnn in the 



Cortical 



(3039) 



Cortical Body, insertad througth the Lignous 

 pärt, by which Insertions tlie Sap, like the 

 Bloud of the disseminations of the Arteries, is 

 conveyed to its intimate parts: Our Author con- 

 jeeturing, that the design, whereto all these parts 

 are together concurrent, is tlie Circulation of 

 t'ie Sap. 



Having thus declared ihe degrees ofVege- 

 ta.ion in the Root he next shews the Contiuu- 

 ance thereof in the Trunk; the observables and 

 parts of which are, 1. The Skin derived from 

 the Cuticle of tlie Seed: 2. The Cortical Body, 

 originated from the parenchyina of the Seed: 

 3. The Lignous Body, being the Prolongation 

 of the Inner Body, distributed in the Lobes and 

 Plume of the Seed: 4. The Jnsertment and 

 Pith, proceeding also from the Plume, as the 

 same in the Root from the Radicle; so that, as 

 to their Substantial parts, the Lobes of the 

 Seed, the Radicle and Plime, the Root and 

 Trunk, are all one. Here notice is taken of 

 the Shooting of the Lignous body in breadth; 

 wherein are observable its Fibres, Production of 

 Rings, and especially Pores; and these of three 

 sorts, greater, lesser and least of all; all conti- 

 nuous and prolonged by the length of the 

 Trunk: which he proveth by an Experiment 

 made by Mr. Hook, by Alling up (suppose in a 

 piece of Char-coal) all the said Pores with 

 Mercury, which appears to pass quite through 

 tbem, as is visible by a good Glass. The re- 

 sult of all is, that the Woody part of a Vege- 

 table is nothing eise but a Cluster of Jnmimer- 

 able and extraordinary small Vessels or coneave 

 Fibres. He farther shews the Iisertions of the 

 Cortical body in the Trunk, and the Pores of 

 those Insertions; in none of which pores he 

 could observe any thing, that may have the true 

 nature and use of Valves; the non-existence of 

 which he is asserting. He discourses also of 

 tlie Position and Fract of the Pores: and coii- 

 cludeth this Chapter by declaring, How the 

 Trunk ascends; How its parls, in consequence 

 of that Ascent are disposed ; How that disposi- 

 tion is consequent to the different nature and 

 energy of the Sap; what the efFects are ofthat 

 difference; which way, and how the Sap as- 

 cends , viz. by the joynt subserviency of the 

 Lignous and the Cortical Body in some, but in
