I know
not whether the capillary Pipes in the bodies of small Trees, which we call
their _Microscopical pores_, may not be such; and whether the congruity of
the sides of the Pore may not yet draw the juyce even higher then the Air
was able by its bare pressure to raise it: For, Congruity is a principle
that not only unites and holds a body joyned to it, but, which is more,
attracts and draws a body that is very near it, and holds it above its
usual height.
And this is obvious even in a drop of water suspended under any Similar or
Congruous body: For, besides the ambient pressure that helps to keep it
sustein'd, there is the Congruity of the bodies that are contiguous. This
is yet more evident in Tenacious and Glutinous bodies; such as Gummous
Liquors, Syrups, Pitch, and Rosin melted, &c. Tar, Turpentine, Balsom,
Bird-lime, &c. for there it is evident, that the Parts of the tenacious
body, as I may so call it, do stick and adhere so closely together, that
though drawn out into long and very slender Cylinders, yet they will not
easily relinquish one another; and this, though the bodies be _aliquatenus_
fluid, and in motion by one another, which, to such as consider a fluid
body only as its parts are in a confused irregular motion, without taking
in also the congruity of the parts one among another, and incongruity to
some other bodies, does appear not a little strange.
