HYDROSCOPE, an instrument anciently used for the measuring of time.
The hydrocope was a kind of water-clock, consisting of a cylindrical tube, vertical at bottom: the cylinder was graduated, or marked out with divisions, to which the top of the water becoming successively contiguous, as it trickled out at the vertex of the cone, pointed out the hour. See HYDROSTATICS, sect. vi.
