From The Collaborative International Dictionary of English v.0.48 :

  Siphon \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.
        [1913 Webster]
     2. (Zool.)
        (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.
            [1913 Webster]
     3. A siphon bottle.
        [1913 Webster]
     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 aerated 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.
