Show Measuring Time In India. In' parts of southern. India to mcas-uro mcas-uro time there was used a thin copper bowl about Ave inches la diameter and rather deeper than half a sphere, having a very small holo at tho bottom. bot-tom. Tho bowl, placed in a vessel containing water nnd floating thereon, there-on, gradually filled. At tho expiration ot an arranged Interval it sunk, and a boy or another watcher then struck a pong and thus announced tho tlmo. It showed the lapse of periods of for-ty-nvc minutes with tolerablo accuracy, accu-racy, but tho tlmo varied with tho temperature of the water. It was possible by the Introduction of a cylinder cyl-inder containing & floating piston which worked on a cog wheel to Indicate In-dicate the hours. |
