Later, in 1892, Pupin in America, and Ebert in Germany, imitated the coronal streamers by means of electrical discharges in low vacua between small conducting bodies and strips of tinfoil placed on the outside of the containing glass receptacles.
These wires are inclosed in glass tubes which pass underground and run to the place whither the dispatch is to be transmitted. The extremities of the wires reach a similar plate of glass, which is likewise affixed to a table and carries strips of tinfoil similar to the others.
Joe carefully measured a square of paper to the required dimensions, and then used it as a pattern in cutting out the others. He soon had a number of neat squares ready, which he handed to Bob, who immersed them in the melted wax. While the paper was soaking this up, Joe cut out a corresponding number of tinfoil squares, leaving a projecting tongue on each one to serve as a terminal.
"Well, he resumed as the print widened visibly, this tinfoil negative is wrapped around a cylinder at the other end of the line and a stylus with a very delicate, sensitive point begins passing over it, crossing the parallel lines at right angles, like the other lines of a regular halftone.
On the other hand, Leyden jars with tinfoil coatings showed considerable absorption, and this he thought due to want of close contact between the foil and the glass. To test this he suggested that mercury coatings be tried. Mr. Kapp considered the loss of power in condensers due to two causes: first, that due to the charge soaking in; and second, to imperfect elasticity of the dielectric.
Mr Tinfoil then entered into the arrangement for remuneration, and walked away; and I was conning over in my mind whom I should select from my brother watermen, and whether I should ask old Stapleton to take the other oar in my boat, when I heard a voice never to be mistaken by me "Life is like a summer day Warmed by a sunny ray. "Lower away yet, Tom. That'll do, my trump.
We then cut small strips of writing paper, and after marking 25c on some of them and 50c, 75c, and $1.00 and $2.00 on an occasional one, we pasted a strip of this paper on each cake of soap, some prizes and many blanks. We then cut the tinfoil and wrapped it nicely around the soap and put it into the tin box.
"Oh, it's easy enough, I believe," said Tom. "You get a sheet of tinfoil, lay it on a table, cover it with quicksilver, and then put the glass on it, and press it with weights till the tinfoil and quicksilver stick to the glass, and then you have a regular mirror." "You seem to know all about it, Tom," said the Vicar, who had dropped in for a chat, and to hear how the telescope was going on.
In one of his 1878 patents, the use of wax to take the records in place of tinfoil is indicated, and it is chiefly to the adoption of this material that the success of the 'perfected phonograph' is due. Wax is also employed in the 'graphophone' of Mr. Tainter and Professor Bell, which is merely a phonograph under another name.
"Well," he resumed as the print widened visibly, "this tinfoil negative is wrapped around a cylinder at the other end of the line and a stylus with a very delicate, sensitive point begins passing over it, crossing the parallel lines at right angles, like the other lines of a regular halftone.
