The Hour-Glass Clock.

A novelty in a clock is announced which has no special merit except as a curiosity. The object of new invention in the clock line is to avoid frequent winding, while at the same time maintaining the regularity that constitutes tiie chief value of a clock. This device is somewhat on the hour-glass order. It registers the time accurately by the! running of the mercury from one end of the glass to the other. The clock hs| built In two sections, and an Indicator marks the precise time consumed by tiny; mercury in passing from the upper to the lower. This clock must be turned when the upper section Is emptied,: which is really about as much work ui winding the clock.—The New Yorkj Ledger. j
