32 A Twenty-second Memoir on the Law of Storms. [No. 1. 



We have no evidence that this Cyclone was at all felt at sea, for 

 it was on the night of the 12th and 13th May that it visited Chitta- 

 gong and its track was evidently from the N. 42° East to the S. 42° W. 

 or out to sea ; while the Brig Colonel Burney Capt. Crisp, whose note I 

 shall add, was at the centre of a small Cyclone on the night of the 11th 

 and 12th May at a distance of about 300 miles to the S. W. of Chitta- 

 gong, so that if this little Cyclone had been the same which passed over 

 Chittagong, it would have commenced there at South or S. E. and 

 ended at K. "W. or exactly contrary to the changes which took place 

 there. The Calcutta newspaper letter, p. 25, mentions the dismast- 

 ing of the Yacht Mystery in a Cyclone at 400 miles to the S. W. 

 of Chittagong ; at 3 i. m. of the 13th when the Cyclone was still 

 raging at the station. Hence it is unnecessary to discuss whether 

 it was the same. It was probably a small one of the same kind, 

 but her Log has not reached me, I regret to say. 



The ship Sir Robert Seppings had also on the 11th and 12th May 

 while running up the Coast and abreast of Coringa, on the 12th 

 some unsettled weather for which proper precautions were taken, 

 but there is nothing in her log worth occupying our space. 



The H. C. Surveying Brig Krishna, Lt. Fell, was also running up 

 from off Cape Negrais on the 12th, to the light vessel on the 15th f 

 but she carried a fresh monsoon, giving her from 5 to 7 and 8 knots 

 the whole way, though with squally unsettled weather and her 

 Barometer at 5 P. M., on the 14th at 29.59, when the remarks are 

 as follows : 



" Moderate breeze with a very hazy, damp sultry atmosphere ; clouds 

 very unsettled to the Westward, working to the Southward and again 

 passing to the North in circles. At Ilk. 20 p. m. wind suddenly shifted 

 to the North with a short interval of calm then to the JN". N. E. with a 

 hard squall and rain." 



This occurred when the vessel was at about 225 miles to the 

 S. W. b. W. of Chittagong and forty-three hours after the centre 

 of the Chittagong Cyclone had passed over that station, so that if 

 it was, as it might have been, for I do not pretend to say that it was 

 so, the disk of that Cyclone which had lifted up and travelled 

 onwards without descending, it had progressed at about five miles 

 per hour, a slow rate, which however agrees well enough with its
