(gcide) | Barometer \Ba*rom"e*ter\, n. [Gr. ba`ros weight + -meter: cf. F.
barom[`e]tre.]

atmosphere, and hence for judging of the probable changes of

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.
