almost stationary character at Chittagong. We have abundant 

 proof that Cyclones descend ; and some that they ascend, and are 

 seen overhead after a certain progress at sea and on shore ; but this 

 amounts to but little more than a supposition, though it is not one 

 to be omitted. 



The following is the note of the " Colonel Bumey's" log forward- 

 ed to me by Capt. Crisp, who unfortunately had no Barometer on 

 board. 



Extract from the " Colonel Burney's" Log. 



May 11th, 1849.— In Latitude 17° 51' N. and Long. 88° 16' East; 

 wind at E. S. E. with high sea from the Southward ; at sunset, hard 

 gales ; hove to, with head to the Southward ; at 11 p. m. wind sud- 

 denly shifted from East to North (yet the high sea running high 

 from South) ; midnight shifted with a sudden gust to West, and 

 blew with great violence until 3 a, m. of the 12th, when it shifted 

 to S. W. and continued to blow in hard gales until 4 a. m. of the 

 13th, when the gale abated. Just before the gale abated, experienc- 

 ed very heavy peals of thunder attended with lightning and heavy 

 rain; "at 8 A. M. strong breezes wind" shifted to North; at 2 p. m. 

 wind shifted to S. W. steady breezes and sea subsiding. 



The three days previous to the gale had nothing but calms, 

 during which time we experienced a set to the Westward of fifteen 

 miles per day, whereas during the gale we were set seventy miles to 

 the Eastward. 



Remarks. 



It adds much interest to this remarkable Cyclone that it occurred 

 at a spot like Chittagong, which is itself probably an extinct volcanic 

 site, and situated at the extremity of the great volcanic band of the 

 Pacific Ocean and Eastern Archipelago. The last severe earthquake 

 on record there is that of April, 1762 (Philosophical Transactions, 

 Vol. LIII. pp. 252 to 259) and it is added in the last of the accounts 

 there given, that two volcanoes had " broken out." No gale seems 

 to have accompanied this event. 



I can find no newspaper record of the hurricane of 1824, alluded 

 to in Capt. Elson's report, and in reply to a reference to that gentle- 

 man, he says : —
