Aneroid barometerBarometer Ba*rom"e*ter, n. [Gr. ? weight + -meter: cf. F.
barom[`e]tre.]
An instrument for determining the weight or pressure of the
atmosphere, and hence for judging of the probable changes of
weather, or for ascertaining the height of any ascent.
Note: The barometer was invented by Torricelli at Florence
about 1643. It is made in its simplest form by filling
a graduated glass tube about 34 inches long with
mercury and inverting it in a cup containing mercury.
The column of mercury in the tube descends until
balanced by the weight of the atmosphere, and its rise
or fall under varying conditions is a measure of the
change in the atmospheric pressure. At the sea level
its ordinary height is about 30 inches (760
millimeters). See Sympiesometer. --Nichol.

Siphon barometerSiphon 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.
