pUcaced in cloathing the Twig or Stem of the plant, (which 
we take to be the reafon of the orderly break- 
ing forth of the Leaves,) fo do we tjiink of the Veins5the!r 
perpetual companions. Aodjas we have faid,the Fibres of 
the Leaves are joined in the Twigifoare thofeof the twigs 
in the Branches 5 thofe of the branches in the Trank or 
body of the tree: The like alfo ia an inverted order we 
kem to oblervc in the feveral Coats and Ramifications of 
the Ro*ot. This the feveral Circles of bleeding Orifices ia 
tranfverfe cuts feems to confirm. 
But moreover in the Roots of plants,if a fimple Coat be 
fcparated and expofed betwixt your eye and the light, the 
Veins appear to be ftrangely intangled and implicate, and 
not in the fame fimple ord^r as in the Leaves. The like 
we think of the Bark of the bodies of Trees, which we can- 
not diftinguifli from the Roots of plants 5 though there is, 
indeed, fomething (at leaft at certain feafons of the year^ 
in the Root, which is not to be found in any pare of the 
plant befides. 
From what hath been faid, it may well be doubted, whe- 
ther there is any finus or common Trunk, into which all 
the veins are gathered ? But rather,that there are a multi- 
tude of equally big veins, each exifting apart by it felf. We 
indeed have found it very difficult fo to exhauft the plant 
of its milkie juice, as to kill it, though we have given it 
very many incifions to that purpofe* Divers other ioflan* 
ces dierc are, which favour the Difcontinuance of the 
Veins,and the little relation and intercourfe they have with 
one another s as one branch ofa Tree having fair and well 
grown fruitjbefore the other branches of the fame tree and 
fruit blofTom or have leaves ; from the different fituatioa 
and other circumftances of culture $ the indefinite and per- 
petual growth of a Tree 5 the Cyon governing, &c^ 
And thus far we have taken our information concerning 
thefe Veins, partly by the appearance they make in tranS 
verfe cuts, and partly by the help of a Microfcope 3 which 
laft indeed has Ihewed us focacthing of their number, 
mag.
