Página 72 - Why," he exclaimed, with much ardor of manner, " if that is so, and the presence of electricity can be made visible in any desired part of the circuit, I see no reason why intelligence should not be transmitted instantaneously by electricity.
Página 41 - I believe that science is now ripe for the application, and that there are no difficulties in the way, but such as ingenuity and enterprise may obviate. But what form of the apparatus, or what application of the power will prove best, can, I believe, be only determined by careful experiment. I can say, however, that, so far as I am acquainted with the...

Página 84 - Magazine, January 20, 1838 ; and the invention of Morse is justly entitled to take date from early in the spring of 1837. And in the description of Davy's invention, as given in the publication of January 20, 1838, there is nothing specified which Morse could have borrowed ; and we have no evidence to show that his invention ever was or could be carried into successful operation. In relation to Wheatstone, there would seem to be some discrepancy in the testimony. According to Professor Gale's testimony,...
Página 11 - As the possibility of this experiment has not been easily conceived, I shall here describe it. Two iron rods, about three feet long, were planted just within the margin of the river, on the opposite sides. A thick piece of wire, with a small round knob at its end, was fixed on the top of one of the rods, bending downwards, so as to deliver commodiously the spark upon the surface of the spirit. A small wire fastened by one end to the handle of the spoon, containing the spirit, was carried across the...
