 Southerly winds 3. Southerly winds are moft frequently accompanied with

 parts of our hemifphere ; but northerly and eajlerh/, with clear, 

 dry, and ferene weather. Becaufe foutherly winds are not 

 only warmer, proceeding from warmer climates, butalfo more 

 highly electrified than the foil of the colder countries into 

 which they flow. Hence the copious vapours they contain are 

 quickly deprived of part of their electron, and thus converted 

 into clouds; but the fuperior ftrata of the atmofphere. under 

 which the fouthern air is introduced, not being fupported by air 

 as denfe as that which fubfifted under them before their intro- 

 duction, necetfarily defcend and mix with the inferior fouthern air ; 

 by this intermixture they are warmed, and deprive the clouds 

 already formed and in its vicinity of part of their electron, or 

 perhaps in conformity to the eleventh principle, they are them- 

 felves deprived of part of their electron by thofe clouds, and 

 the vapours they contain are thus converted into clouds ; in 

 either way clouds differently electrified mufr be formed. Hence 

 proceeds their gradual attraction to each other which termi- 

 nates in thofe gentle fhowers that ufually accompany this wind. 

 Northerly and eafterly winds on the contrary, proceeding from 

 colder countries are lefs highly electrified than the foil of the 

 countries they invade ; and hence from the oppofite reafons to 

 thofe juft mentioned they introduce ferene weather and a dik 

 pofition adverfe to nubification. 



The reafons hitherto adduced to explain the different effects 

 of thefe different winds, evidently arofe from an ignorance of 

 the origin and progrefs of thefe winds. It was imagined that 

 foutherly winds, flowing into colder countries were fuddenly 

 cooled by an intermixture with the colder air of thofe coun- 

 tries, and that thus their vapours were condenfed into rain, 

 yet, even fo, this intermixture could only produce clouds and 

 not rain, but in fact this intermixture cannot take place, ex- 

 cept with the fuperior and unmoved ftrata of the atmofphere, 

 and thefe alone could not produce numerous clouds, much 

 lefs copious rains ; for the air of the countries into which thefe
