   Gun cotton (Chem.), a general name for a series of
      explosive nitric ethers of cellulose, obtained by steeping
      cotton in nitric and sulphuric acids. Although there are
      formed substances containing nitric acid radicals, yet the
      results exactly resemble ordinary cotton in appearance. It
      burns without ash, with explosion if confined, but quietly
      and harmlessly if free and open, and in small quantity.
      Specifically, the lower nitrates of cellulose which are
      insoluble in ether and alcohol in distinction from the
      highest (pyroxylin) which is soluble. See Pyroxylin, and
      cf. Xyloidin. The gun cottons are used for blasting and
      somewhat in gunnery: for making celluloid when compounded
      with camphor; and the soluble variety (pyroxylin) for
      making collodion. See Celluloid, and Collodion. Gun
      cotton is frequenty but improperly called
      nitrocellulose. It is not a nitro compound, but an ester
      of nitric acid.

      mounted on a carriage or other holder, and having a
      reservoir containing cartridges which are loaded into the
      gun or guns and fired in rapid succession. In earlier
      models, such as the Gatling gun, the cartridges were
      loaded by machinery operated by turning a crank. In modern
      versions the loading of cartidges is accomplished by
      levers operated by the recoil of the explosion driving the
      bullet, or by the pressure of gas within the barrel.
      Several hundred shots can be fired in a minute by such
      weapons, with accurate aim. The Gatling gun, Gardner
      gun, Hotchkiss gun, and Nordenfelt gun, named for
      their inventors, and the French mitrailleuse, are
      machine guns.
