Whether theyare Aer-Feffels, or Sap-Veffels, is dubious. For, on the one hand, becaufe they emit no Sap, or bleed not,and alfo ftand adjacent tothe ders *tis probable that they are Aer-Veffels. On the other hand, they may be Sap-Veffels 5 notwithftanding that they bleed not: Becaufe the non-emiffionof Sapis notan infallible and concluding argument of an Aer-Vefel.

This Parenchyma of the Barque is the fame, as toits Subfiance, both in the Root and Trunk, Yet as to the Texture ofits Parts, inthe owe, and in the other, there is This obfervable difference, ViZ Book IIL of Trunks. 109 Branches, cat Tranfverfly : and by the feveral Figures which teprefent them. Jo. §, FIRST then, for the Eleven firlt Quarters, the Veffels of the Barque are only of Two Kinds, And thefe, in the firft Eight, fem Tab.22. to be Roriférous (defcribed alfo in the Azatomy of Roots) (a) and A : thofe which are‘common to moft, ifnot to all Plants, {e. the Lympha- ce) fe oa duds. Yet inall the Eight, they are, in refpeé both of their Propor. © 3+ 3+ 22s tion, and Pofition, very different. So in Hazel and Afb they are but few. In Holly and Barberry more. In Apple, Pear, Plum, Elm, ftill more numerous. And ofthofe three Fruits, in an Apple, or Plum, more than in a Pear. 11. §. Again, as their Proportion, {0 likewife their Pofition is di- vers. For in Holly, the Lymphadués or inner Vefls next to the Wood, ftand in Rays. Yet fo numerous and clofe together, as to make one Tab. 4 “9 Entire Ring, In Hazel, they ftand more in Oblong Parcels. In Bar- » berry, they ftand likewife in Parcels, but they are fo many HalfOuvals, 3> 24. The utmoft Mefféls or Roriferous of all Three,make a Ring, 12, g. Again, in Apple, Pear, and Plum, the Lymphadués are Ra- diated. The Roriferous are neither Radiated, nor make an entire Rings Typ, 5-36 but ftand in Peripherial Parcels. Much after the fame manner, they 9 nM alfo {tand in El. In Ah, the Veféls make Two Rings 5 but neither he ofthem Radiated: the inmoft Ring or LymphaduGs, confifting ofAr- ched Parcels, and the utmoft or Roriférovs Vefféls, of Round ones: And whereas in all the foregoing, the Lyuphedués are {till contiguous That in the Barque of the Root, cut tranfverfly, the faid Parenchyma (as hath been fhew'd ) is ufually, moreorlefs, difpofed into Diametral Tab.7,8,9.

So in Rhws or Sumach, although part of the Paren- Tab.31,34, chymabe difposd into Diametral Rays: yet are thofe Rays extended ec. not half way through the Bargue. So alfo in Fig-tree, Worm-wood, Thiftle, and others. Whatis further obfervable in the Texture of the Parenchyma, I thall thew in the defcription of the Pith. 8. §. THE, Vefels of the Barque, are, as I fhall alfo thew, diver- fifyed many ways. But there are fome Things, wherein, in all Sorts of Plants, they agree. Firff, in ftanding, moft numeroufly,in or near, the inner Margin of the Barque. Secondly, in being always, and only Sap-Vefféls.. have viewed fo many, that at leaft, I can fecurely affirm thus much, That ifthere be any Heteroclital Plants, wherein they are found otherwife, there isnot Oxe, in Five Hundred.

And that thefe Veféls in cach Barque ofthe {aid Eight Bran: fo from hence ; In that their Pofitions are altogether Heterogeneous: Yet in both Conftant, Regular and Uniform. I fay, there feems to be no Reafon, why the felf fare Kind or Species of Vefels, thould have adifferent, yea a contrary Pofition in one and the fame Plant and that Contrariety, not Accidental, but Regular and Conftant. 14. §. FOR the Three next Quarters fc. the Ninth, Tenth and Eleventh, the seffels of the Barque are alfo different in Number, Pofttion, Tab: 30, Size and Kind. In Pine, whichis the Eleventh, they are fewer. Walwut the Ninth, more. In Fig, the Tenth, moft numerous. In 3! 3? 15. §. So for their Pofition. In Pine, the inmoft makea Radiated Ring. The utmoft ftand sraghng up and down, without any certain order. In Walnut the inmoft make alfo a Radsated Ring; The utmoft make a Double Rizgs not Radiated, but of Round Parcels. In Fig, the inmoft makealfo a Radiated Ring. But the utmoft make though’ the Number and Diftances ofthe Braces, are very different: as a Double and fometimes Treble Ring, not of Radiated, nor Round, but Arched Parcels, Thavealready fhewedin the Avutomy of Roots. 9. §. THE Properties, whereby the faid Vefels of the Barque are of the two former, Walnut and Fig, are thus different: thofe certain- {pecificated and diftinguifhed one from another, both in the fame Plant,’ and in the feveral Species of Plants, are very many. Which Properties, are not Accidental, but fuch as hew the Conftant and Univerfal Defign of Nature. All which thal! be demonftrated by the Defeription of feveral Quarters of the Slices, of fo many Kinds . Branches * v7 16. §. Thirdly, they are alfo different in Kind. ly, of the Fig, are fo, being Lympheduds and Latteals. Thofe, I think, The Lympha- duds makethe inmoft Radiated Ring. The outmoft which make the other Rings in Arched Parcels, are the Laitifers. 17. §, That they are diftin® Kizds of Veffels, is evident for two Reafons..
