themfelves Organical ; but their very Sides alfo, feem to be compofed 
of other Parts, which are Organical, fü. of Lignous or Tomy Fibres, 
Which Fibres, ftanding clofe or contiguous in a round Figure, they 
make one Tubulary Body, which I call the Lymphedud ofa Plant. And 
itis probable, That thefe Fibres themfelves, are alfo Tubulary. That 
is, that a Lymphedutt, ist a {mall Tube, made up or compofed of 
other, yet much finaller Tubes, fet round together in a Cylindrich Fi- 
gure... As if we fhould imagine a company of Straws, which are fo 
many fmall Pipes, to be joyned and fet round together, fo as to make 
another greater Pipe, anfwerable to a hollow Cane, The Cane, I fay, 
is as the Evmphedudt 3 and the Straws are as the Fibres whereof it is 
compofed. By which alfo appears, the admirable fmallneß of thefe 
Fibres. For there are fome Lympheduöfs, which may be reckoned fifty 
times fimaller than a Horfe-Hair. Allowing therefore but Twenty of 
the aforefaid Fibres to make a Thred fo big as one Lymphedud ; then 
one of the faid Fibres, muft be a Thoufand times fmaller than a Hor/é- 
Hair, That thefe Fibres, whereof the Lymphedudls are made, are 
themfelves made up of other Fibres, is not altogether improbable, 
32. $. Thefe Fibres, although parallel; ‘yet are they not een, 
but only contiguous being contained together ina Tubulary Figure, 
by the Weftage of the Cortical Fibres, as in Chapter the Fourth will 
better be underftood. 
33. $. The firft notice I took of the Compofition and Texture of 
thefe Vejfels, fo far asthe belt Glaffes yet known, will admit 5 was in 
a very white and clear piece of Afb-wood torn, with fome care, by the 
length of the Tree, and objected to a proper Light. They feem alo 
fometimes difcernable in fome other clear Woods, asin very white Fir, 
©. And having formerly demonftrated, that the Ligzons Part of a 
Plant, is annually made or augmented out of the inner part of the 
Barque, wherein the Lymphaduéfs always ftand: we may reafonably 
fuppofe the fame Lympheduéts to have the like Conformation in the 
Barque, as in the Wood. 
34. $. AndI am the rather induced to believe, that I am not mif- 
taken in this Defeription, upon thefe two Confiderations. Firf, that 
herein the Analogy betwixt the Veféls of an Animal and a Plant, is the 
more clear and proper. For as the Sanguineons Vefels in an Animal 
are compofed of a number of Fibres, fet round, ina Tubulary Figure, 
together : fo are thefe Lympheduöls ofa Plant, Secondly, in that here- 
in, there is a more genuine refpondence betwixt thefe, and the other 
Veffels ofa Plant it (AR; fo, the Aer-Vefels 3 which are made up of a 
certain number of Round Fibres, ftanding collaterally, or fide to fide 
as Į have already obferved in the Anatomy of Roots. So that it is the 
lefsftrange, that the Lyespheduéts (hould be made up of Fibres, fince 
the Aer-Veffels are eviden tly fo made. Only with this difference, that 
whereas in the Aer-Veféls, the Fibres are poftured or continued Spi- 
rally: here, inthe Lymphedués, they ftand and are continued only 
in frraight Lines. 
35.§. THE STRUCTURE of the Ladiferous and Gum-Veffels, which 
have avery ample Bore, is more apparent. And, by the belt Glafts 
I have yet ufed, they feem to be made, chiefly, by the Conftipation 
of the Bladders of the Barque. Thatis to fay, That they are fo many 
Chauels,
