physics which relates to the determination of the humidity of bodies, particularly of the atmosphere, with the theory and use of the instruments constructed for this purpose.

An instrument which shows whether there is more or less moisture in the atmosphere, without indicating its amount.

Having the property of readily inbibing moisture from the atmosphere, or of the becoming coated with a thin film of moisture, as glass, etc.

on in very far north; most northern; hence, very cold; fright, as, a hyperborean coast or atmosphere. The hyperborean or frozen sea. C. Butler (1633).

acuo as in the open air,and therefore are not influenced by the weight or pressure of the atmosphere. Sir I. Newton. This standing revelation . . . is sufficient to influence their faith and practice, if they attend. Attebury. The principle which influenced their obedience has lost its efficacy. Rogers.…

A discharge of atmospheric electricity, accompanied by a vivid flash of light, commonly from one cloud to another, sometimes from a cloud to the earth. The sound produced by the electricity in passing rapidly through the atmosphere constitutes thunder.

Of or pertaining to the atmosphere and its phenomena, or to meteorology. Meteorological table, Meteorological register, a table or register exhibiting the state of the air and its temperature, weight, dryness, moisture, motion, etc.

The science which treats of the atmosphere and its phenomena, particularly of its variations of heat and moisture, of its winds, storms, etc.

An apparatus which transmits automatically to a central station atmospheric changes as marked by the anemometer, barometer, thermometer, etc.

An instrument for recording minor fluctuations of atmospheric pressure, as opposed to general barometric surges.
