Hooke, Robert, 1635-1703

"Micrographia Some Physiological Descriptions of Minute Bodies Made by Magnifying Glasses with Observations and Inquiries Thereupon"

_Scheme._ which round
Area ABCD represents a part of the surface about one eighth part of an Inch
in Diameter: Those little holes, which to the eye look'd round, like so
many little spots, here appear'd very regularly shap'd holes, representing
almost the shape of the sole of a round toed shoe, the hinder part of
which, is, as it were, trod on or cover'd by the toe of that next below it;
these holes seem'd wall'd about with a very thin and transparent substance,
looking of a pale straw-colour; from the edge of which, against the middle
of each hole, were sprouted out four small transparent straw-colour'd
Thorns, which seem'd to protect and 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.
