DISTURBANCES AT BOMBAY. 14? 



Variations in the temperature of the gases, 

 however those variations may be produced, are 

 the great causes of winds, both irregular and 

 periodical ; and these variations may be combined 

 with an increase or a decrease of vapour, in such 

 ways as shall create atmospheric currents, and at 

 the same time affect the barometer in such 

 different modes, as to produce all those various 

 and complicated phenomena, that have, hitherto, 

 baffled enquirers on the subject.
