CLIMATE, in its most general ac- ceptation, embraces all those modifica- tions of the atmosphere by which our organs are sensibly affected; such as tem- also on the ensemble of moral sensatioiis which mankind experience in the differ- ent zones. There are two general causes on which the climate peculiar to any country principally depends: First, its distance from the equator; second, its al- titude above the level of the sea; but their effect is generally modified by many circumstances exerting a partial influ- ence. Among these may be enumerated the configuration and extent of the coun- try; its inclination and local exposure; the direction of the chains of mountains by which it is intersected, or which are in its vicinity; the nature of the soil as it is more or less favorable to radiation, absorption, and evaporation; the proxim- ity to, or distance from, seas; the action of winds blending the temperatures of different latitudes; and even the changes produced by cultivation. The apprecia- tion of all these causes, which modify the results deduced from the consideration of
