He then turned back to his tool-case and lifted therefrom, first a Bunnell sounder, and then a Wheatstone bridge, of the post-office pattern, a coil of KK wire, a pair of lineman's pliers, and a handful or two of other tools.
Lyon Playfair, Professor Owen, George Stephenson, Mr. Smith of Deanston, and Professor Wheatstone. Sir William Follett was not of the party, and did not set foot within Drayton Manor during George Stephenson's visit there. The story is a revival of an anecdote first told long before George Stephenson was born.
Two years later, he called attention to the value of thermo-electricity as a mode of generating a current by means of heat, and since then a variety of thermo-piles have been invented, some of which have proved of considerable advantage. Wheatstone abandoned his idea of transmitting intelligence by the mechanical vibration of rods, and took up the electric telegraph.
His father encouraged him in this, and finally took him out of the uncle's charge. At the age of fifteen, Wheatstone translated French poetry, and wrote two songs, one of which was given to his uncle, who published it without knowing it as his nephew's composition. Some lines of his on the lyre became the motto of an engraving by Bartolozzi.
Three years later it was tried on a Government line from London to Portsmouth. In 1845, the Electric Telegraph Company, the pioneer association of its kind, was started, and Mr. Cooke became a director. Wheatstone and he obtained a considerable sum for the use of their apparatus.
A joint patent was taken out for their inventions, including the five-needle telegraph of Wheatstone, and an alarm worked by a relay, in which the current, by dipping a needle into mercury, completed a local circuit, and released the detent of a clockwork.
About the same time with yourself Professor Wheatstone, of London, and Dr. Steinheil, of Germany, proposed plans of the electro-magnetic telegraph, but these differ as much from yours as the nature of the common principle would well permit; and, unless some essential improvements have lately been made in these European plans, I should 'prefer the one invented by yourself.
The following January Alexander Bain took out a patent for an electro-magnetic clock, and he subsequently charged Wheatstone with appropriating his ideas.
The same year Professor Daniell, of King's College, London, brought out his constant-current battery, which befriended Morse in his experiments, as it afterwards did Cooke and Wheatstone, Hitherto the voltaic battery had been a source of trouble, owing to the current becoming weak as the battery was kept in action.
In 1841 a difference arose between Cooke and Wheatstone as to the share of each in the honour of inventing the telegraph. The question was submitted to the arbitration of the famous engineer, Marc Isambard Brunel, on behalf of Cooke, and Professor Daniell, of King's College, the inventor of the Daniell battery, on the part of Wheatstone.
