It will be noticed in these observations that there had been a deci- 

 dedly rapid fall of the barometer at Kampore Beauleah, Mymensing, 

 Serajgunge, Dhubri, and Bogra, while at Sanger Island, Jessore, Calcutta, 

 Berhampore pressure had fallen only slightly. The slight area of com- 

 paratively low pressure which was in Central Bengal on the 7th April 

 appears to have again advanced in a north-easterly direction and to have 

 slightly intensified, and on this day a very distinct low pressure area 

 existed in North Bengal, and was represented by such stations as Rung- 

 pore, Bogra, Serajgunge, Mymensingh, and Dhubri. The marked con- 

 trasts of temperature and humidity still existed over the north and 

 centre of the Province, but scarcely to such an extent as on the 7th, and 

 the lines in PI. XXV. shewing the increase of temperature by 5° and of 

 humidity by 25 per cent, on this day are still rather close. The most 

 important feature is, however, the change which is seen in the condition 

 of the centre of the province when the humidity and wind directions are 

 considered together, and, as already indicated, the moist southerly wind 

 which had advanced rapidly over the country from the 6th to the 7th 

 had been forced back between the 7th and the 8th with apparently
