 of the centre of the vortex near to Macao. 



At Canton, (60 miles N. of Macao,) the typhoon began 

 on the evening of the 5th, after three or four days of very 

 hot weather, with northerly winds, and continued through- 

 out the night and the next day. Its violence was greatest 

 about two o'clock on the morning of the 6th. The follow-
