This copper core was covered with Chatterton's compound, which served as water-proofing. This was surrounded by four layers of gutta-percha, cemented together by the compound, and about this h

But Thomson solved it with his siphon recorder. In this a small coil is suspended between the poles of a large magnet; the coil being free to turn upon its axis. When the current from the cable passes through the coil it moves, and so varies the position of the
