"Have you proved the sand-glass by the oscillations of a bullet?"
"Suspended by a rope yarn drawn out from the top of a coil of soaked hemp? Undoubtedly."

"I tested the sand-glass by the bullet, and checked the log by a round shot."
"Of what size was the shot?"
"One foot in diameter."
"Heavy enough?"
