Lesage, at Geneva, in 1774, actually constructed a telegraph arranged in this manner, the end of each wire having a pith-ball electroscope attached. Lamond, in 1787, employed a single wire, employing an electrical machine and electroscope in each of two rooms, and thus talking with Madame Lamond by the peculiar movements of the pith-balls according to an agreed code; and Reusser, in 1794, proposed tMadame Lamond by the peculiar movements of the pith-balls according to an agreed code; and Reusser, in 1794, proposed the employment of letters formed by spaces cut out of parallel strips of tin-foil pasted on sheets of glass, which would appear luminous on the passage of the electric spark. In 1795, Cavallo proposed to transmit letters and numbers by a combination of sparks and pauses. Don Silva, in Spain, appears to have previously suggested a similar process. See electrical apparatus. In 1816, Mr. Ronalds experimented with a frictional electricity telegraph at Hammersmith. The current had to pass
