1849-1 Seventeenth Memoir on the Law of Storms. 267 



PART II. 

 Cyclones of the Northern Pacific Ocean. 



Our data for the tracks of Cyclones in this part of the world are very 

 few, but they are highly worth recording, as presenting two great points 

 of interest. The first is their conformation to the general laws of pro- 

 gression and rotation for this part of the globe, and the second that of 

 the tendency of the tracks to the Westward of the meridian within the 

 tropics. We might indeed, to these two, add a third consideration, 

 which is, that the day cannot be far distant when by means of steam 

 from the Western coasts of North America this part of the ocean will 

 become both for England and. America a high road to China, and when- 

 ever this takes place, all knowledge relative to its Cyclones must have 

 high value. 



Track V. 



Second Tyfoon of the H. C. S. Duke of Buccleugh and fleet. 



The Swift Sloop of War, Captain Hayward, with a fleet of sixteen 

 ships, of which 13 were the Hon'ble East India Company's China 

 fleet of the season, left Macao Roads on the 15th June 1797, near the 

 height of the S. W. moonson, and took, as usual in those days, when beat- 

 ing down the China Sea was thought an impossibility even for a man 

 of war, the Eastern route by the Pacific Ocean. While yet within the 

 Bashees on the 19th June, the fleet experienced a first severe Tyfoon, 

 which separated it into two divisions which remained during the next 

 two Tyfoons, 1st and 8th of July at such a moderate distance from 

 each other (about 300 miles) that we are fortunately enabled to trace 

 the tracks of these Cyclones to some distance and with much cer- 

 tainty. 



My documents are first, Logs of the China Ships received from the 

 India House, and next a copy of that part of the preface to Capt. 

 Lynn's Star tables which describes the Buccleugh' s distress. I have 

 also had the advantage, for the Log of the Canton, of comparing it 

 with that of Mr. Adamson, who was her chief officer.
