Carbon \Car"bon\ (k[aum]r"b[o^]n), n. [F. carbone, fr. L. carbo
   coal; cf. Skr. [,c]r[=a] to cook.] (Chem.)
   An elementary substance, not metallic in its nature, which is
   present in all organic compounds. Atomic weight 11.97. Symbol
   C. it is combustible, and forms the base of lampblack and
   charcoal, and enters largely into mineral coals. In its pure
   crystallized state it constitutes the diamond, the hardest of
   known substances, occuring in monometric crystals like the
   octahedron, etc. Another modification is graphite, or
   blacklead, and in this it is soft, and occurs in hexagonal
   prisms or tables. When united with oxygen it forms carbon
   dioxide, commonly called carbonic acid, or carbonic oxide,
   according to the proportions of the oxygen; when united with
   hydrogen, it forms various compounds called hydrocarbons.
   Compare {Diamond}, and {Graphite}.

   {Carbon compounds}, {Compounds of carbon} (Chem.), those
      compounds consisting largely of carbon, commonly produced
      by animals and plants, and hence called organic compounds,
      though their synthesis may be effected in many cases in
      the laboratory.

            The formation of the compounds of carbon is not
            dependent upon the life process.      --I. Remsen
      

   {Carbon dioxide}, {Carbon monoxide}. (Chem.) See under
      {Carbonic}.

   {Carbon light} (Elec.), an extremely brilliant electric light
      produced by passing a galvanic current through two carbon
      points kept constantly with their apexes neary in contact.
      

   {Carbon point} (Elec.), a small cylinder or bit of gas carbon
      moved forward by clockwork so that, as it is burned away
      by the electric current, it shall constantly maintain its
      proper relation to the opposing point.

   {Carbon tissue}, paper coated with gelatine and pigment, used
      in the autotype process of photography. --Abney.

   {Gas carbon}, a compact variety of carbon obtained as an
      incrustation on the interior of gas retorts, and used for
      the manufacture of the carbon rods of pencils for the
      voltaic, arc, and for the plates of voltaic batteries,
      etc.

Compound \Com"pound\, n.
   1. That which is compounded or formed by the union or mixture
      of elements ingredients, or parts; a combination of
      simples; a compound word; the result of composition.
      --Shak.

            Rare compound of oddity, frolic, and fun.
                                                  --Goldsmith.

            When the word ``bishopric'' was first made, it was
            made as a compound.                   --Earle.

   2. (Chem.) A union of two or more ingredients in definite
      proportions by weight, so combined as to form a distinct
      substance; as, water is a compound of oxygen and hydrogen.

   Note: Every definite chemical compound always contains the
         same elements, united in the same proportions by
         weight, and with the same internal arrangement.
