204 A Twentieth Memoir on the Law of Storms. [No. 2. 



Bancoorah, and we have next to consider whether that described on 

 the 28th in Capt. SherwilFs report from Berhampore, could have been 

 the Midnapore one curving to the N. N. Eastward? Berhampore 

 bearing N. N. E. 120 miles from Midnapore, and the calm centre 

 passing Berhampore by Capt. SherwiU's exact observations at 4 a. m. 

 on the 28th, or about 16 hours after it was abreast of Midnapore, 

 would give a rate of travelling of about 8 miles per hour. I am 

 thus inclined to think, that this was the original main Cyclone, which 

 was deflected by the line of the Rajmahal hills, and that the remarka- 

 ble appearance which I have described at Calcutta, if it was what 

 we might readily suppose it to be, (and I still think it may have 

 been a division of the Cyclone seen by me,) did not give rise to the 

 Moorshedabad Cyclone. There is nothing, however, impossible in the 

 heavy bank to the Eastward having been an independent Cyclone, for 

 we have no reports from Jessore, Dacca, or Krishnagur, in which 

 districts it would have been felt, but if it had been violent we should 

 probably have had some. Moderate gales, no one, I regret to say, 

 thinks it worth while to report. 



We have, nevertheless, it will be seen, traced this formidable Cyclone, 

 from undoubted evidence over a track of 1000 miles as in the follow- 

 ing table.

Its average course at sea (for we should in fairness reject its land 

 progress) was N. 17° 38* W. and the entire average rate of its pro- 

 gress for the whole five days was 8.4 miles per hour. The variations 

 in the rate of travelling, exactly correspond with what has been before
