Telegraph \Tel"e*graph\, n. [Gr. ? far, far off (cf. Lith. toli)
   + -graph: cf. F. t['e]l['e]graphe. See {Graphic}.]
   An apparatus, or a process, for communicating intelligence
   rapidly between distant points, especially by means of
   preconcerted visible or audible signals representing words or
   ideas, or by means of words and signs, transmitted by
   electrical action.

   Note: The instruments used are classed as indicator,
         type-printing, symbol-printing, or chemical-printing
         telegraphs, according as the intelligence is given by
         the movements of a pointer or indicator, as in Cooke &
         Wheatstone's (the form commonly used in England), or by
         impressing, on a fillet of paper, letters from types,
         as in House's and Hughe's, or dots and marks from a
         sharp point moved by a magnet, as in Morse's, or
         symbols produced by electro-chemical action, as in
         Bain's. In the offices in the United States the
         recording instrument is now little used, the receiving
         operator reading by ear the combinations of long and
         short intervals of sound produced by the armature of an
         electro-magnet as it is put in motion by the opening
         and breaking of the circuit, which motion, in
         registering instruments, traces upon a ribbon of paper
         the lines and dots used to represent the letters of the
         alphabet. See Illustration in Appendix.

   {Acoustic telegraph}. See under {Acoustic}.

   {Dial telegraph}, a telegraph in which letters of the
      alphabet and numbers or other symbols are placed upon the
      border of a circular dial plate at each station, the
      apparatus being so arranged that the needle or index of
      the dial at the receiving station accurately copies the
      movements of that at the sending station.

   {Electric telegraph}, or {Electro-magnetic telegraph}, a
      telegraph in which an operator at one station causes words
      or signs to be made at another by means of a current of
      electricity, generated by a battery and transmitted over
      an intervening wire.

   {Facsimile telegraph}. See under {Facsimile}.

   {Indicator telegraph}. See under {Indicator}.

   {Pan-telegraph}, an electric telegraph by means of which a
      drawing or writing, as an autographic message, may be
      exactly reproduced at a distant station.

   {Printing telegraph}, an electric telegraph which
      automatically prints the message as it is received at a
      distant station, in letters, not signs.

   {Signal telegraph}, a telegraph in which preconcerted
      signals, made by a machine, or otherwise, at one station,
      are seen or heard and interpreted at another; a semaphore.
      

   {Submarine telegraph cable}, a telegraph cable laid under
      water to connect stations separated by a body of water.

   {Telegraph cable}, a telegraphic cable consisting of several
      conducting wires, inclosed by an insulating and protecting
      material, so as to bring the wires into compact compass
      for use on poles, or to form a strong cable impervious to
      water, to be laid under ground, as in a town or city, or
      under water, as in the ocean.

   {Telegraph plant} (Bot.), a leguminous plant ({Desmodium
      gyrans}) native of the East Indies. The leaflets move up
      and down like the signals of a semaphore.

Facsimile \Fac*sim"i*le\, n.; pl. {Facsimiles} (-l?z). [L. fac
   simile make like; or an abbreviation of factum simile made
   like; facere to make + similes like. See {Fact}, and
   {Simile}.]
   A copy of anything made, either so as to be deceptive or so
   as to give every part and detail of the original; an exact
   copy or likeness.

   {Facsimile telegraph}, a telegraphic apparatus reproducing
      messages in autograph.
