220 Hurricanes of the Asiatic Seas. 



From a comparison of the foregoing accounts, it appears that 

 those ships suffered most severely, which fell under the northern 

 semi-circle of the storm. This result, probably, would not follow 

 in the higher latitudes, where the storm has recurved to the north- 

 ward and commenced its easterly course. 



Hurricanes of the Asiatic Seas. 



It is generally believed that the hurricanes of the Indian seas 

 occur only or chiefly at the change of the monsoons ; but this 

 opinion appears to be of doubtful accuracy. 



From the valuable meteorological journal which appears monthly 

 in the Canton Register, I have compiled the following statement 

 of the periods of change in the N. E. and S. W. monsoons at 

 that place :

 The American ship Parachute, at Boston from Calcutta, experienced 



a very heavy gale to the northward of 18° N. lat. in the Bay of Bengal, 

 on the 23d, 24th, and 25th of August, 1831. Spoke the Nandi from 

 Bengal to Liverpool, dismasted in the gale. — London shipping lists. 



Bombay, June ^Ath, 1837. — One of the severest gales that has occurred 

 here for the last forty eight years, commenced on the evening of the 14th 

 inst. On the morning of the 15th the scene of destruction was displayed. 

 The roaring of the wind and thunder was truly awful ; large palmira 

 trees, six feet in diameter and seventy feet in height, were torn up by 

 the roots, and many houses completely unroofed. 



The accomits of hurricanes in the Asiatic seas, given us by 

 Col. Reid, are also more common to the regular monsoons than 

 to the periods of change. 



Tyfoon at Manilla and Hurricane at Balasore, Oct. 1831. 



The following account of a tyfoon in the China sea in 1831, 

 is interesting insomuch as it affords probable grounds for connect- 

 ing the hurricane at Manilla, Oct. 23-24, with that of Oct. 31, 

 at Balasore, on the shores of the Bay of Bengal. 



Eitract from the private journal of Wm. F. Grisivold, Esq., Master 

 of the ship Panama, on a voyage to Canton, October, 1831. 



* From these and like statements of the changes of the monsoons at other points, 

 some useful inductions might be obtained.
