"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."

"Have you waxed the yarn lest it should stretch?"

"Yes."

"Have you tested the log?"

"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?"
