The following is extracted from the Overland Friend of China of 

 Sept. 1846, and the Cyclones it relates to are doubtless one, or perhaps 

 two of them connected with that of the Mischief but I have been un- 

 able to obtain further details. 



* It is possible there may be some error of the copyist here, or some little aber- 

 ration of the Cyclone track, but it does not affect the general result.
