there were two of them, we cannot be very far wrong as to this part 

 of our estimate. 



Another remark to be made, and it is one of much importance, is, 

 that throughout this long period of years, this is the only instance 

 in which we find a storm in so low a latitude as that of 11° N. the 

 Castlereagtis Track, No. IX, being in about 12° N. The curves 

 of those of the Ariel and Moffatt, if their storms reached so far, 

 are only conjectural here, and reach the Coast of Cochin China 

 in 12°, while the Castle Huntley's storm, Track No. XII, and the 

 Calcutta Thetis' cross the usual route in 13°. We may then, as this 

 space is as much crossed as any other part of the sea, infer, that when 

 storms do occur so low as the latitudes of 10° or 11° N., they are of 

 extreme violence, and perhaps (at least in ti>is instance) also, they 

 travel with great rapidity.

Hong Kong Tyfoon o/2\st July, 1841. 



In this year we have three remarkable tyfoons. Two in July, 

 of which the centre passed close to Hong Kong, where great damage 

 was done to the fleet lying there, and one which seems to have raged in 

 about lat. 14° 20' in November. Of this last I grieve to say, our records 

 are very imperfect, though I personally applied again and again to 

 parties, who could have afforded me such as would have enabled 

 me to lay down a certain track for the storm.
