Scope note
Barometers of the type in which the column of liquid in the tube has above it a body of confined air or other gas (instead of a vacuum as in the mercurial barometer), so that the pressure of the atmosphere acts against the weight of the liquid and the elastic pressure of the gas; a thermometer is attached for correction of the readings according to the expansion or contraction of the gas with changes of temperature.
