First, in that it had a very little solid substance, in comparison of the
empty cavity that was contain'd between, as does more manifestly appear by
the Figure A and B of the XI. _Scheme_, for the _Interstitia_, or walls (as
I may so call them) or partitions of those pores were neer as thin in
proportion to their pores, as those thin films of Wax in a Honey-comb
(which enclose and constitute the _sexangular celts_) are to theirs.
Next, in that these pores, or cells, were not very deep, but consisted of a
great many little Boxes, separated out of one continued long pore, by
certain _Diaphragms_, as is visible by the Figure B, which represents a
sight of those pores split the long-ways.
I no sooner discern'd these (which were indeed the first _microscopical_
pores I ever saw, and perhaps, that were ever seen, for I had not met with
any Writer or Person, that had made any mention of them before this) but me
thought I had with the discovery of them, presently hinted to me the true
and intelligible reason of all the _Phaenomena_ of Cork; As,
First, if I enquir'd why it was so exceeding light a body? my _Microscope_
could presently inform me that here was the same reason evident that there
is found for the lightness of froth, an empty Honey-comb, Wool, a Spunge, a
Pumice-stone, or the like; namely, a very small quantity of a solid body,
extended into exceeding large dimensions.
