The following would be the alphabetical signs, as arranged from the above directions:
| A | rrrrr | I or Y | llrll | R | rrrll |
| B | rrrrl | K | lrrrl | S or Z | rrlrl |
| C | rrrlr | L | rlrrr | T | llrlr |
| D | rrlrr | M | rrlll | U | rlllr |
| E | rlrlr | N | lllll | V | lrrll |
| F | lrrrr | O | lrlll | W | llllr |
| G or J | lrlrr | P | lrlrl | ||
| H | rlrrl | Q | llrrr |
| Numerals. | |||
| 1 | rllll | 6 | rllrr |
| 2 | rrllr | 7 | lllrl |
| 3 | rlrll | 8 | llrrl |
| 4 | rllrl | 9 | lrrlr |
| 5 | lllrr | 0 | lrllr |
It will be seen, that, by representing the letters and numerals with these variously combined deflections of the needle, words and sentences may be transmitted. At the end of each letter there is a suspension of the action of the bar for a short time, and at the end of a word, a still longer pause. This plan of an electric telegraph was tried for a distance of one mile and a quarter, in Göttingen. Of its further success, we are not informed.
Experiment of Messrs. Taquin & Ettieyhausen.[28]
“Messrs. Taquin and Ettieyhausen made experiments with a telegraphic line over two streets in Vienna, 1836. The wires passed through the air and under the ground of the Botanic garden.”
No other account appears to have been given of their experiments than that quoted above.
Electro Magnetic Printing Telegraph, invented by Alfred Vail,
September, 1837.
Soon after my connection with Professor Morse as copartner, and at the time I was constructing an instrument for exhibiting the advantages of his telegraph to a committee of Congress, it occurred to me, that a plan might be devised, by means of which the letters of the alphabet could be employed in recording telegraphic messages. I immediately gave it my attention, and produced the following plan:
