To send a me age by tele dispensed with and the signals read "by sound," the receiving magnet with its armature being known as a sounder. The currents from the line are pa ed through the magnet a (see cut) and cause it to attract its armature b, which Morse Telegraph Sounder. brings the stop e against the anvil d, giving out a clear click for each current sent. The audible signals consist of short and long intervals of contact, corresponding to dots and dashes, and are interpreted by means of the Morse alphabet (which see, under alphabet ). When the line is more than a mile or two in length, the signals are usually received first on a relay, which is similar in form to a sounder, but so constructed that its armature responds to feeble currents. The end of this armature acts as a key in a local circuit which operates the sounder or register.- Needle-telegraph. See def. 1.-Octoplex telegraph, a telegraph by which eight me ages can be sent at the same time over a single wire. - Optical telegraph. (a) A semaphore. (b) An electric telegraph of the needle or pointer cla . - Phonoplex telegraph, a telegraph in which multiplex telegraphy is secured by combining telephonic communication with an ordinary telegraph system. - Pneumatic telegraph. (a) A form of telegraph, formerly in use, in which me ages were transmitted by the agency of a column of water under pneumatic pre ure. (b) A system of transmi ion for signals in which a bell is sounded and a pointer caused to indicate a me age by the compre ion of air in a reservoir at one end of a long tube, the compre ion being transmitted to the opposite end of the tube. This is used in hotels, manufactories, etc., and to transmit steering and steaming directions on shipboard.-Poly grammatic telegraph. See poly grammatic. - Printing telegraph, a telegraph in which the me age is printed IMG:content-0029.png:[merged small][merged small][merged small][ocr errors][merged small][merged small] I now observed that Belläal was standing very near me.

A board on which are hoisted or otherwise marked the numbers of horses about to run in a race, together with the names of their jockeys.

A cable containing wires used for transmitting telegraphic me ages.

The two ends of a break in the line-wire are connected to the terminals t, t, and the break is bridged over by the lever beach time it is depre ed during the transmi ion of the me age. When the key is not being used the lever is held against its back-stop 8 by the spring p, and the break is bridged over by putting the lever l in the position shown.
