printing-type

In Professor Bonelli's system the dispatch is set up in printing-type, and placed on a little carriage, which is made to pass beneath a comb with five teeth, which are in communication with five aërial wires of the line, at the extremity of which these same wires are joined to the five teeth of a second comb, under which passes a chemically prepared paper, carried along on a little carriage similar to the one at the other end on which the printing-type is placed.

If under this arrangement the electric circuit of a battery composed of a sufficient number of elements, and distributed in a certain order, be completed, then, at the same time that the first comb is passing over the printing-type at the one end, the second comb at the other end will trace the dispatch on the prepared paper in beautiful Roman letters, and with so great a rapidity that it may be expected that five hundred messages of twenty words each will be transmitted hourly.
