Webster's 1913 Dictionary
  1. \Si"phon\, n. [F. siphon, L. sipho, -onis, fr. Gr. ??? a
    siphon, tube, pipe.]
    1. A device, consisting of a pipe or tube bent so as to form
       two branches or legs of unequal length, by which a liquid
       can be transferred to a lower level, as from one vessel to
       another, over an intermediate elevation, by the action of
       the pressure of the atmosphere in forcing the liquid up
       the shorter branch of the pipe immersed in it, while the
       continued excess of weight of the liquid in the longer
       branch (when once filled) causes a continuous flow. The
       flow takes place only when the discharging extremity of
       the pipe ia lower than the higher liquid surface, and when
       no part of the pipe is higher above the surface than the
       same liquid will rise by atmospheric pressure; that is,
       about 33 feet for water, and 30 inches for mercury, near
       the sea level.
    2. (Zo["o]l.)
       (a) One of the tubes or folds of the mantle border of a
           bivalve or gastropod mollusk by which water is
           conducted into the gill cavity. See Illust. under
           {Mya}, and {Lamellibranchiata}.
       (b) The anterior prolongation of the margin of any
           gastropod shell for the protection of the soft siphon.
       (c) The tubular organ through which water is ejected from
           the gill cavity of a cephaloid. It serves as a
           locomotive organ, by guiding and confining the jet of
           water. Called also {siphuncle}. See Illust. under
           {Loligo}, and {Dibranchiata}.
       (d) The siphuncle of a cephalopod shell.
       (e) The sucking proboscis of certain parasitic insects and
       (f) A sproutlike prolongation in front of the mouth of
           many gephyreans.
       (g) A tubular organ connected both with the esophagus and
           the intestine of certain sea urchins and annelids.
    3. A siphon bottle.
    {Inverted siphon}, a tube bent like a siphon, but having the
       branches turned upward; specifically (Hydraulic
       Engineering), a pipe for conducting water beneath a
       depressed place, as from one hill to another across an
       intervening valley, following the depression of the
    {Siphon barometer}. See under {Barometer}.
    {Siphon bottle}, a bottle for holding a["e]rated water, which
       is driven out through a bent tube in the neck by the gas
       within the bottle when a valve in the tube is opened; --
       called also {gazogene}, and {siphoid}.
    {Siphon condenser}, a condenser for a steam engine, in which
       the vacuum is maintained by the downward flow of water
       through a vertical pipe of great height.
    {Siphon cup}, a cup with a siphon attached for carrying off
       any liquid in it; specifically (Mach.), an oil cup in
       which oil is carried over the edge of a tube in a cotton
       wick, and so reaches the surface to be lubricated.
    {Siphon gauge}. See under {Gauge}.
    {Siphon pump}, a jet pump. See under {Jet}, n.
  2. \Si"phon\, v. t. (Chem.)
    To convey, or draw off, by means of a siphon, as a liquid
    from one vessel to another at a lower level.
