d cover those cavities, from either side
two; neer the root of this Plant, were sprouted out several small branches
of a kind of bastard _Coralline_, curiously branch'd, though small.

And to confirm this, having lately the opportunity of viewing the large
Plant (if I may so call it) of a Sponge _petrify'd>_, of which I made
mention in the last Observation, I found, that each of the Branches or
Figures of it, did, by the range of its pores, exhibit just such a texture,
the rows of pores crossing one another, much after the manner as the rows
of eyes do which are describ'd in the 26. _Scheme_: _Coralline_ also, and
several sorts of white _Coral_, I have with a _Microscope_ observ'd very
curiously shap'd. And I doubt not, but that he that shall observe these
several kinds of Plants that grow upon Rocks, which the Sea sometimes
overflows, and those heaps of others which are vomited out of it upon the
shore, may find multitudes of little Plants, and other bodies, which like
this will afford very beautifull objects for the _Microscope_; and this
_Specimen_ here is adjoin'd onely to excite their curiosities who have
opportunity of observing to examine and collect what they find worthy their
notice; for the Sea, among terrestrial bodies, is also a _prolifick_
mother, and affords as many Instances of _spontaneous_ generations as
either the Air or Earth.

Observ. XXIV. _Of the surfaces of _Rosemary_, and other leaves._

This which is delineated within the circle of the second _Figure_ of the
14. _Scheme_, is a small part of the back or under side of a leaf of
Rosemary, which I did not therefore make choice of because it had any thing
peculiar which was not observable with a _Microscope_ in several other
Plants, but because it exhibits at one view,

First, a smooth and shining surface, namely, AB, which is a part of the
upper side of the leaf, that by a kind of hem or doubling of the leaf
appears on this side. There are multitudes of leaves, which surfaces are
like this smooth, and as it were quilted, which look like a curious quilted
bagg of green Silk, or like a Bladder, or some such pliable transparent
substance, full stuffed out with a green juice or liquor; the surface of
Rue, or Herbgrass, is polish'd, and all over indented, or pitted, like the
Silk-worm's Egg, which I shall anon describe; the smooth surfaces of other
Plants are otherwise quilted, Nature in this, as it were, ex
