les, yet to the naked eye there scarce appears any such thing; which
may afford us a good argument to think, that even in those bodies also,
whose _texture_ we are not able to discern, though help'd with
_Microscopes_, there may be yet _latent_ so curious a _Schematisme_, that
it may abundantly satisfie the curious searcher, who shall be so happy as
to find some way to discover it.

Next, we here find a Stone, though to the naked eye a very close one, yet
every way perforated with innumerable pores, which are nothing else but the
_interstitia_, between those multitudes of minute globular particles, that
compose the bulk it self, and these pores are not only discover'd by the
_Microscope_, but by this contrivance.

I took a pretty large piece of this stone, and covering it all over with
cement, save only at two opposite parts, I found my self able, by blowing
in at one end that was left open, to blow my spittle, with which I had wet
the other end, into abundance of bubbles, which argued these pores to be
open and pervious through the whole stone, which affords us a very pretty
instance of the porousness of some seemingly close bodies, of which kind I
shall anon have occasion to subjoyn many more, tending to prove the same
thing.

I must not here omit to take notice, that in this body there is not a
_vegetative_ faculty that should so contrive this structure for any
peculiar use of _vegetation_ or growth, whereas in the other instances of
vegetable porous bodies, there is an _anima_ or _forma informans_, that
does contrive all the Structures and _Mechanismes_ of the constituting
body, to make them subservient and usefull to the great Work or Function
they are to perform. And so I ghess the pores in Wood, and other
vegetables, in bones, and other Animal substances, to be as so many
channels, provided by the Great and Alwise Creator, for the conveyance of
appropriated juyces to particular parts. And therefore, that this may tend,
or be pervious all towards one part, and may have impediments, as valves or
the like, to any other; but in this body we have very little reason so
suspect there should be any such design, for it is equally pervious every
way, not onely forward, but backwards, and side-ways, and seems indeed much
rather to be _Homogeneous_ or similar to those pores, which we may with
great probability believe to be the channels of _pellucid_ bodies, not
directed, or more open any one way, then any other, being equa
