Report by Dr. Sullivan, 36th Regt. N. I. ; from Jumalpore. 

 Lat. 24° 58' N., Long. 82° 58' E. 



On the night of the 20th instant, this station was visited by 

 a severe storm, which continued throughout the night without 

 abatement, and in a diminished rate for the whole of the next 

 day. The wind set in from the eastward at about 5 p.m. from 

 which point it continued to blow, with but slight deviation 

 to the southward, was accompanied by heavy rain, but no 

 thunder or lightning, and came in frequent and tremendous 

 gusts; it gradually reached its utmost violence at about mid- 

 night. 



For several days previously, the weather was unusually sultry, 

 with a clear sky, and scarcely a breath of air stirring. Ther- 

 mometer 86° at noon ; from which it suddenly fell to 78° on 

 the day of the storm, and has scarcely exceeded that range 

 since. 



Jumalpore stands on the western bank of the Burhampooter 

 river; is pretty clear of heavy tree jungle in its vicinity; the 

 nearest hills are distant about 50 miles, in a nearly due north 

 direction ; the prevailing wind is easterly, which blows for nine 

 months in the year.

 dead calms until 4 p.m., when the wind commenced to blow 

 strong and steadily from NNW. accompanied with rain, and 

 so continued for some hours. During the night it shifted round 

 to SE. and blew a gale with constant rain ; wind veering about 

 between two or three points to either side of SE., and coming 

 on with occasional gusts much harder than others. This con-

 some occasional appearances of an abatement. Ther. 78° in the
