Hooke, Robert, 1635-1703

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

I could not find
either with my naked Eye, or a _Microscope_, that any of the broken pieces
were of a regular figure, nor any one like another, but for the most part
those that flaw'd off in large pieces were prettily branched.
The ends of others of these drops I nipt off whilst all the bodies and ends
of them lay buried under the water, which, like the former, flew all to
pieces with as brisk a noise, and as strong a motion.
Others of these I tried to break, by grinding away the blunt end, and
though I took a seemingly good one, and had ground away neer two thirds of
the Ball, yet would it not fly to pieces, but now and then some small rings
of it would snap and fly off, not without a brisk noise and quick motion,
leaving the Surface of the drop whence it flew very prettily branched or
creased, which was easily discoverable by the _Microscope_. This drop,
after I had thus ground it, without at all impairing the remnant that was
not ground away, I caused to fly immediately all into sand upon the nipping
off the very tip of its slender end.
Another of these drops I began to grind away at the smaller end, but had
not worn away on the stone above a quarter of an inch before the whole drop
flew with a brisk crack into sand or small dust; nor would it have held so
long, had there not been a little flaw in the piece that I ground away, as
I afterwards found.
