A very interesting electrical clock was exhibited at a recent American exposition. r ' : liis clock is different from the ordinary in having no hands. Minutes are indicated by means of sixty radial rows of lights, each containing thirty-two electric globes. The hours are indicated by shorter rows of colored lights. In place of the hands, two lines of lights sweep over the face of the dial, one indicating minute and the other hours. Each second the illumination in an outer circle of lights move forward one lamp, and when an entire circuit has been completed, the row of minute lights is advanced one interval. The hou rhand moves at 3min. intervals. The dial is formed on the fact of a huge pendulum, which swings to and fro over an arc of 15 feet. The pendulum is 48ft long, and its weight, with the 5485 lamps and 11,000 connections required, is 30001 b. Over a mile of wire was used in making the connection of the clock.
