Sir W. F. Cooke's original electric alarum, unknown maker, British, 1835-1840.

This sample of gutta-percha insulated cable dates from around 1848-1849. It was possibly the cable laid by the Electric Telegraph Company between its Lothbury headquarters and Shoreditch (probably the railway station), a distance of approximately one mile. Though it was a good insulator, gutta percha tended to disintegrate after a few years in harsh city environments.
