Threatening weather and rain in the Gulf
States, clearing in New England, elsewhere
generally fair.
Factsto be Reaeabered.-1 The moisture of the
atmosphere divides itself into three heads: /.
AtmOmetry, or the determination of the amount
of water passing into the air by evaporation.
II. Hygrometry, or the determination of the
amount Of water present in the air in vapor-
Gus form. III. Hyetometry, or the determine
tion of the amount of water condensed out of
the atmosphere in the form of rain, hail or
snow.
2 Aqueous vapor is the most abundant ele-
ment in the composition of the atmosphere,
next to its principal constituents, nitrogen and
oxygen.
3. Next TO temperature, aqueous vapor is
the most important of all meteorological phe
nomina because by its sensitiveness to the
action of heat, and its liability to change of
condition from gaseous to liquid and solid, and
rice reTSd, it is capable of exerting a great in
fuenee on almost all meteorological processes.
g. Evaporation is the process Of water pass
ing into the state of vapor, and condensation
the converse process of vapor passing into the
state of water.
