Among the most interesting are remembered those that S.W.Wilkins carried on for a long time between France and England.

Like Cooke and Wheatstone, he thought of using as a receiver an apparatus which in some features resembles the present receiver of the submarine telegraph.

Later, George E.Dering, then James Bowman and Lindsay, made on the same lines trials which are worthy of being remembered.
But it is only in our own days that Sir William H.Preece at last obtained for the first time really practical results.

Sir William himself effected and caused to be executed by his associates--he is chief consulting engineer to the General Post Office in England-- researches conducted with much method and based on precise theoretical considerations.

He thus succeeded in establishing very easy, clear, and regular communications between various places; for example, across the Bristol Channel.
