the colder regions; but they are lefs frequent, becaufe the va- 

 riations of wind in different diredions which introduce and 

 intermix clouds differently eledlrified are lefs frequent ; this 

 might be proved by inflaacing the rainy feafons between the 

 tropics, were it not that this illuiiration would extend this 

 paper to too great a length. Even in moderately elevated ficua- 

 tions between the tropics, if infulated and of fmall extent, as the 

 iiland of St, Helena, it feldom rains. 



2do. That, in the temperate latitudes, rains are alfo more 

 copious, though commonly lefs frequent in /iim'/er than in w/n- 

 ter, for the reafons already affigned. Dy fummers are then the 

 confequence of'uniform winds, iVom whatever quarter they may 

 blow, as -wet fummers are of their variation, particularly if in op- 

 pofite direcftions, and if they reach heights fufBcient to intermix 

 the clouds that fubfifted during the reign of their aptagonifts. 



3do. Southerly winds are moft frequently accompanied with 

 rain, in mofl parts of Kurope at leaft and probably in moft parts 

 of our hemifphere ; but northerly and eiftsrly^ with clear, dry, 

 and ferene weather. Becaufe fouther'.y wmds are not only war- 

 mer, proceeding from warmer cliniaus, but alfo more highly 

 eledrified than the foil of the colder countries into which they 

 flow. Hence the copious vapouis ihey contain are quickly depri- 

 ved of p rt of their eleciron, and thus converted into clouds; but
