2 Seventeenth Memoir on the Law of Storms. [Jan. 



at the time at sea, or laid down from previous research, depends the 

 successful management of the ship when involved in or threatened by 

 them ; and it will be seen that, as from analogy, I had supposed it 

 possible, so we have now found that some rare anomalies of tracks to 

 the Eastward of the Meridian do take place in two dangerous parts of 

 the sea, the Straits of Formosa and Bashee Passage. 



In the part relative to the storms of the Northern Pacific Ocean, I have 

 comprised all that 1 have been able to collect relative to this great, and 

 to us, very important field of our research, comprising as it does nearly 

 the whole Eastern Coast of China, the stormy seas of Japan, and that 

 great tract extending to the N. W. Coast of America, and bounded per- 

 haps only by the Equator,* in which these wonderful meteors take their 

 rise. 



1840. 



Tracks A. and B. 



The Golconda's Storm, September 1840. 



Log of the Ship Hashmy, Captain Buckle, from Singapore to China. 



In my fourth Memoir, (Journal Asiatic Society for 1841, Vol. X.) I 

 showed that this unfortunate ship, the Golconda, with 300 Madras troops 

 on board, was in all probability lost on the 23d — 24th September, about 

 the spot where the centres of two tyfoons, the one from the E. S. E., 

 and the other from the S. by E. met ; but though indubitably there 

 were two storms, it was not possible from the logs of one ship for each 

 stormf to affirm that we had laid down correctly the exact line of the 

 tracks. 



Having subsequently received a capitally well kept log from Captain 

 Buckle of the Hashmy, I find with great satisfaction that the track of 

 the Northern Cyclone is perfectly correct as to direction, the only correc- 

 tion to be made being, that the centre of the 22nd, the first day, requires 

 to be placed 70 miles farther to the Eastward : but at the approach of 

 Cyclones, the estimation of the ship's distance from the centre is 

 always of great uncertainty without hourly observations of the Baro- 

 meter and careful measurement of the ship's run. 



* At the Kingsmill groupe, upon the Equator, hurricanes are known to prevail, 

 t The London Thetis and the Calcutta Thetis.
