Curious Time-Piece.
About 1679 Nicholas Grallier de Servierre, an old soldier who had served in the Italian army, constructed a whimsical clock. A figure of a tortoise, dropped into a plate of water, having the hours marked on the rim, would float around and stop at the proper time, telling what o'clock it was. A lizard ascended a pillar, on which the hours were marked, and pointed to the time as it advanced. A mouse did the same thing by creeping along an hour-marked cornice.
