At Station A there is shown the talking apparatus employing the Wheatstone bridge arrangement.
Wheatstone was knighted in 1868, after his completion of the automatic telegraph.
If it was mainly invented by Wheatstone, it was chiefly introduced by Cooke.
The year of the telegraph—1837—was an important one for Morse, as it was for Cooke and Wheatstone.
Mr. Wheatstone has already made experiments which fully illustrate this point.
Wheatstone by his knowledge of Ohm's law and the electro-magnet was probably able to enlighten him.
The scientific men know little or nothing absolute on the subject: Wheatstone is the only man near the mark.'
Wheatstone and he obtained a considerable sum for the use of their apparatus.
Wheatstone subsequently investigated the conditions necessary to obtain electro-magnetic effects at a long distance.
To do this we use an instrument called the Wheatstone bridge.
