The greatest height of the Barometer in the five months of 1841 was in November, 30-246. 



The least • November, 28-262. 



• The greatest twelve months •••1842 October, 30-304. 



The least January, 28-509. 



Wliile there is no marked difference in the suiTimer and winter ranges of pressure to be deduced from the 

 means at the observation hours, the extreme ranges of pressure are markedly greater in winter than in summer. 

 With two exceptions, the means of the highest and lowest are less than the means of the four hours.
