DISTURBANCES AT BOMBAY. 135 



begins to flow from the land to the sea, — or the 

 land breeze sets in. It is feeble at first, but 

 increases in strength until it reaches its maximum 

 near day break, say between four and five o'clock, 

 during w'hich time the temperature declines. 

 While, however, the land breeze is thus blowing 

 with increasing strength, and indicating by its 

 force that the atmosphere is becoming consider- 

 ably heavier over the land, the barometer, which 

 should be the measure of increase of atmospheric 

 weight, does not rise as from theory would be 

 confidently expected, but actually falls ! And 

 that this fall of the barometer is not attributable 

 to a rise of thermometric temperature, as that of 

 the morning has been supposed to have been, is 

 evident, because the thermometer was sinking 

 during the whole time. That the fall of the 

 barometer is not due, to a general reduction of 

 atmospheric pressure may also be reasonably 

 inferred, seeing that the land breeze indicates an 

 increase of that pressure over the land, from 

 whence the air is by some cause forced to fiow 

 towards the sea. What then can make the air go 

 with increasing velocity from a part where the 

 atmospheric pressure, as that pressure is measured 

 by the barometer, is successively becoming less 

 and less ? Or rather, we may ask, what can cause
