This Plant is very hardy, enduring 

 our fharpeft Winters in the open 

 Ground j it is increas'd by parting 

 the Roots in Augnji, after the green 

 Leaves decay : It loves a moderate 

 dry Soil, and for the Oddnels of the 

 Plant may merit a Place in a good 

 Garden, although it is of no great 

 Beaut V. 



ANATOxMYi A DifTedion. 



Anatomy of Plants is a cutting, 

 dividing, or fcpararing the Parts or 

 Members of Plants, :n order to dif- 

 covcr the Size, Form, Strudture, 

 and Ufes of their feveral VefTels, for 

 the better promoting their Culture. 



Anatomifts have obferv'd a great 

 Similitude betwixt the mechanick 

 Frame of Plants and Animals : The 

 Parts of Plants feeming to bear a 

 conftant Analogy to thofe of Ani- 

 mals j and the Oeconomy, both 

 Vegetable and Animal, feem to be 

 form'd on the fame Model. 



The Parts of a Plant arc the Rooty 

 the Wbsd, the Bark, and the Vith. 



1. The Roots of the Plants are 

 fpongeous Bodies, whofe Parts are 

 difpos'd tor the eafy Admittance of 

 certain humid Particles, which are 

 prepar*d in the Ground. The Qua- 

 lity of the Root is found much to 

 depend upon the Size of its Vcflels 

 and Pores. 



Monfieur Rcneanme fuppofes the 

 Root of a Plant to do the Olhce of all 

 the Parts in the Abdomen of Animals, 

 which ferve to Nutrition, as the 

 Stomach, Inteflines, ^c, 



Doftor Boerhaave confiders the 

 Roots of Plants to be compos'd of a 

 Number of abfor bent Veffels, which 

 are analogous to the La^eals in Ani- 

 mals.

ning parallel from the Root tKi^ough- 

 out the Stalk : Some call the capilU- 

 ty Tubes arterial Vejfels, becaufe the 

 Sap rifcs from the Root thro' thefe. 

 The Apertures of thefe Tubes are for 

 the moft part too minute to be 

 perceiv'd by the bare Eye, unlefs in 

 a Piece of Charcoal, Cane, or the 

 hke. 



3 . The Bark is the exterior Part of 

 Trees, ferving them for a Skin or 

 Covering : It is generally of a ibungy 

 Texture, and communicates with 

 the Pith by a Multiplicity of fmall 

 Fibres pafling thro' the cabilUty 

 Tn^es, of which the Wood coniilb; 

 fo that the Roots having imbib'd the 

 proper Nutriment of the Tree, it is 

 carry'd up by the Warmth of the Sun 

 thro' the fine arterial Veilels of the 

 Tree to the Top of it, and being 

 there condens'd by the Cold, it does 

 by its own Gravity return down by 

 the VefTels, which lie between tbc 

 Wood and the inner Bark, which do 

 the Office of Veins; and as it paiTes 

 by, leaves fuch Parts of its Juice, as 

 the Texture of the Bark will receive, 

 and requires for its Support. 



4. The Vith is the inward central 

 Part ofa Tree or Plant, anfwering to 

 the Medulla or Marrow of an Ani- 

 mal : As for its Subftance, it conlifts 

 of little tranlparent Globules chain'd 

 or link'd together, ibmewhat hke 

 the Bubbles, that compofe the Froth 

 of Liquor. 



Somefuppofe that the Circulation 

 of the Sap is cfredled by means of the 

 Vith, others ty the B^r/t, and others 

 by the M'bod. 



Borelli, in his Book De motu Am* 

 malium, fuppofes the tender groiv-^ 

 ing Shoot to be diftended like fofc 

 Wax by the Expanlion of the Moift- 

 ure in the ipongy Vith, which di- 

 lating Moifture," he concludes, is 

 hinder'd from returning back, 

 while it expands by the Sponginefs
