Rh  telegraph, and soon found his system capable of great speed; he was thus led to the invention of automatic methods of transmitting signals, of which one is the basis of the most important process now used. He invented electrical clocks, and in 1843 constructed the earth-battery. In 1844 he patented ingenious apparatus for registering the progress of ships, and he also devised electrical methods of playing keyed instruments at a distance.
