Glass tube containing a portion of the first submarine cable between Dover and Calais, plus screws for mounting, unknown maker, England, 1875-1913.

This cable consists of a single copper wire, with gutta-perch insulation, but no armouring. It was held down to the bed of the sea by lead weights attached at 100-yard (91.4 m) intervals. It was laid between Dover and Cap Gris Nez on 28 August 1850, and failed during the first night, reportedly because a fisherman had caught the cable with his anchor and, without realising what it was, cut it free. The cable was not expected to be a permanent success, and the action of the tides soon destroyed the insulating material. It was intended as a test of the possibility of the idea of laying a cable between England and France. Having proved that it was possible, a second cable was laid the following year in 1851.
