From The Times (4 Sept 1852):

"It is in contemplation to have a time-ball put up on a prominent spot at the South Foreland, near Dover, which will act simultaneously with the time-balls at the Observatory at Greenwich and in the Strand. A time-ball, regulated in its falling by the electric current, will enable all the vessels within ten miles distance and in the Downs to have their chronometers corrected to a second. It is also contemplated to fire a large gun simultaneously with the ball falling, the electric fluid being the agent in both cases."
