Pedler and Crombie — On the Tornado which 



[No. 2, 



easterly winds were blowing down the Assam valley, and reached as far 

 as Julpiguri in North Bengal. The limit on this day of the area of the 

 action of the moist southerly winds may be said to be defined by a 

 curved line running through Balasore, Calcutta, Jessore, and Mymen- 

 singh ; and near this line and to the north and west of it, the contrasts 

 of temperature and humidity were exceptionally large. 



The following table gives again some of the principal meteorolo- 

 gical observations taken in Bengal on the morning of the 7th April 1888. 

 Observations taJcen at 10 a. m. April 7th, 1888.

On this day, there was again only a slight change in the pressure, 

 and the barometer fell by about 0-03" to O'Ol" over the whole province. 

 The most rapid fall of pressure took place at such stations as Calcutta, 

 Kishnagar, Jessore, Berhampore, Serajgunge, Bogra, and Dhubri, appa- 

 rently pointing to the advance of the feeble area of low pressure from 

 Chutia Nagpur and West Bengal towards Central and North Bengal. 

 The area of comparatively low pressure was, however, a feeble one, but 

 it is shewn distinctly in PI. XXV. by the shape of the isobars for the 

 day, that for 29*75" dipping down rapidly to the south and including a 

 large part of the centre of the Province. There was no particular 

 change of pressure at Dacca or at any of the neighbouring stations
