which by the weather they had to the Coast of China, I should incline 

 to believe it was. The veering of the wind from N. E. to N. W. at 

 first inclines us to believe, that it may be part of a circular storm, but 

 as it never came farther to the Westward than N. W., I am upon the 

 whole inclined to believe, that the whole was the conflict of the two 

 monsoons, rather than the effect of rotatory storms, and I have not 

 therefore marked even a conjectural track for these. We shall see in 

 1837, Track No. XXV. in the log of the Ariel, another instance of this 

 sort of vibration of a heavy monsoon between N. W. and N. E. at its 

 first setting in.

9tk August, 1829 — A strong tyfoon, though of short duration, 

 was experienced at the entrance of Canton river, by which the H. C. 

 Ship Bridgewater was driven on Lintin Sand and dismasted. The 

 Herefordshire also at anchor, in company with her, fortunately rode 

 out the storm in safety. Three other ships, the Charles Grant, Lady 

 Melville, and Buckinghamshire, also bound to China, were about on 

 the meridian of Canton, and in latitudes from 16° to 19° N. They 

 also experienced bad weather on the 8th and 9th ; but, as I shall sub- 

 sequently shew, this was certainly not the same storm, though Col. 

 Reid, to whom an incorrect copy of the Charles Grant's log had been 

 given, supposes it might have been so.
