on every fide.
Upon confideration of thefe and. divers other Obfervations and
Experiments,. Mr. Brotherton is of Opinion ( i. ) That the fap,
oioft of it,if riot all ,afcends in theVeffels of the Lignous part of
the Tree, and not in the Cortical part, nor between the Cortical
and; Lignous Parts. ^ I ' dg^ri lit* b« ^ anai4 SPjj

defcent of the fap, and notby theafcent, and if there wore: no
defcent, a Tree wou’d; increafe but very little, if at all.
(%.) That there is WedrifinualCirerilatiori of the fap alt the
Summer Seafon, arid during fuch time as the lap is ftirribg,
arid not a defcent at Michaelmas only, as fome have held.
To me it feems very probable, that the Bodies of Plants, as
Well as thofe of moving Animals, are nouFilhed and increafed by
a double Food, the one an impregnated Water, and the other an
mipregnated Air, and that without a convenient fupply of thefe
two, the Vegetable cannot fubfift, at leaft not increafe;, thefe do
mutually mix, and coalefce , and parts of the Air convert to
Water, arid parts of Water to Afe, as fome of thefe latter are
ratify’d arid freed from their Chains, and become Spiritual and
Airy, fo others of the forementioned, are clogged, arid fetter’d,
ami become debafed. To this purpdfe all Plants; as well as Animals,
have a-twofold kind of Roots, one that Branches, and
fpread s into the Earth, and another that fpreads and (hoots into
the Air, both kinds of Roots ferve to receive and carry their
proper nourilhment to the Body of the Plant, and both ferve al-
fo to convey and carry off the ufelef9 Recrements; Ufelefs I
mean any farther, within the Body of the Plant, though ufeful
to it when they are feperated, arid without it, the one for feafom
ingthe Earth and Water; wherein it is Planted, and the other
for feafoning the Air, the method of which I have elftvvhere
explained.
