Barometer \Ba*rom"e*ter\, n. [Gr. ba`ros weight + -meter: cf. F.
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.
Aneroid barometer. See Aneroid barometer, under
Marine barometer, a barometer with tube contracted at
bottom to prevent rapid oscillations of the mercury, and
suspended in gimbals from an arm or support on shipboard.
