26 On the Cyclones of the Nortli Pacific Ocean. 



The plienomena of this great cyclone seem fruitful in instruc- 

 tion to mariners and meteorologists, and present points of prac- 

 tical interest on v/hich we cannot now dwell Without regard 

 to its slow rate of progression, it may be noticed that the phases 

 of the barometer and winds presented in the extensive region on 

 the right of its axis-path^ are in accordance with those found in 

 the two right-hand quadrants of the great cyclones which so 

 often sweep over the United States and the North Atlantic, in 

 the northeasterly course. Thus, during the W.N.W. progres- 

 sion of the cyclone, in lower latitudes, we have seen that the 

 winds of its two right-hand quadrants were from the eastern 

 board, veering to the right as the storm went onward. In like 

 manner our cyclones, in pursuing a northeasterly course after 

 their recurvation in lower latitudes, present us, in their two 

 jight-hand quadrants, with winds veering towards the right on 

 the horizon ; but which, in consequence of this inversion in the 

 course of the storm, commence in a southern quarter, and thus 

 veer westward^ as the storm advances in its course over the places 

 of observation which are on the right of its axis-path. Such 

 cases are often presented ; of which our navigators have much 

 experience in crossing the Atlantic, 



Cyclones of the China Sea and Gvlf of Tonquin. — A cyclone 

 of some intensity was experienced by the flag-ship of the ex- 

 pedition from the 2d to the 4th of August, 1854, in the harbor 

 of Krem-Ling-Moon, near Macao. It set in at K. B., and veered 

 through east and S.E. to S. and S.S. W.; the barometer being 

 at its lowest point, 29'26 inches, on the 3d of August. These 

 phases of the wind show the ship to have been under the two 

 right hand quadrants of the gale, and not very far from its axis. 



I have placed on the chart the track of a cyclone encountered 



by the American ship Panama, in the China Sea, in October, 



1831; which storm had previously passed over the Philippine 

 Islands and proved very destructive at Manilla. 



The track of the cyclone encountered by H. M. ship Ealeigh 

 near the Bashee Islands, in August, 1836, is also indicated. This 

 storm subsequently visited Macao and Canton, in great violence; 

 and, with that of the Panama, was noticed in this Journal* 

 The sketch of its plaCe and progress on the 5th and 6th days of 

 August, with some correction in the track of one of the ships, 

 is here subjoined [See opposite page.] 



The Raleigh, as appears from the logbook since published by 

 Cob Rcid, left Macao Pioads on the first of August, sailing oq 

 the track shown on our sketch, which was engraved previous to 

 the first publication of Col Reid's work on storms. On the 4th, 

 the ship encountered Northeasterly aud northerly winds, with a
