- n. A facsimile telegraph for reproducing writing, pictures, maps, etc. In the transmitter the motions of the pencil are communicated by levers to two rotary shafts, by which variations in current are produced in two separate circuits. In the receiver these variations are utilized by electromagnetic devices and levers to move a pen as the pencil moves.

Yet in all modifications the same thing is done in essentially the same way, and the Voltaic pile, and a little back of that Galvani's frog, is the secret of the telegraph, the telephone, the telautograph, the cable message.
