It was not till 1838 that the English physicist Wheatstone constructed the first stereoscopic apparatus permitting of seeing the relief on examining simultaneously with each of the eyes two different images of an object, one having the perspective that the right eye perceives, and the other that the left eye perceives. This apparatus is described in almost all treatises on physics.
As the Cooke and Wheatstone apparatus became perfected, Cooke was busy with schemes for its introduction. Their joint patent is dated June 12, 1837, and before the end of the month Cooke was introduced to Mr. Robert Stephenson, and by his address and energy got leave to try the invention from Euston to Camden Town along the line of the London and Birmingham Railway.
In 1870 the electric telegraph lines of the United Kingdom, worked by different companies, were transferred to the Post Office, and placed under Government control. Wheatstone was knighted in 1868, after his completion of the automatic telegraph. He had previously been made a Chevalier of the Legion of Honour.
Mavick controls them." "Does he?" said Ault. "Then he can take care of them." "Have you any news, Mr. Ault?" "Nothing to speak of," replied Ault, grimly. "It just looks so to me. All you've got to do is to sell. Make a break this afternoon, about two or three points off." "They are too strong," protested Mr. Wheatstone. "That is just the reason.
It is only fair to note that the discovery of the principle of the relay was made independently by other scientists, notably by Davy, Wheatstone, and Henry, but Morse apparently antedated them by a year or two, and could not possibly have been indebted to any of them for the idea.
Amongst the pioneers of knowledge in this direction were Sir John Herschel who, however, applied himself to the subject in the interests of optics, not of chemistry W. A. Miller, and Wheatstone.
Professor Wheatstone experimented upon the cable intended to unite La Spezia, upon the coast of Piedmont, with the Island of Corsica. It was one hundred and ten miles in length, and contained six copper wires one-sixteenth of an inch in diameter, individually insulated, and each covered with a coating of gutta-percha one-twelfth of an inch in thickness.
Faraday and Wheatstone soon discovered its merits as an insulator, and in 1845 the latter suggested that it should be employed to cover the wire which it was proposed to lay from Dover to Calais. It was tried on a wire laid across the Rhine between Deutz and Cologne. In 1849 Mr.
They were opposed by Wheatstone and his associates, and could not secure even a hearing from the patent authorities. Morse strenuously insisted that his telegraph was radically different from Wheatstone's, laying especial emphasis on the fact that his recording instrument printed the message in permanent form, while Wheatstone's did not.
In this he was mistaken, for the English telegraph of Cooke and Wheatstone was quite different in principle, using the deflection, by a current of electricity, of a delicately adjusted needle to point to the letters of the alphabet. While this was in use in England for a number of years, it was gradually superseded by the Morse telegraph which proved its decided superiority.
