42 Seventeenth Memoir on the Law of Storms. (_J ANe 



A strong gale from the S. east with a very heavy sea on ; sent down topgallant 

 yards, and housed mizen top-gallant mast.

 water than usual. One pump at work. 



At 8 increasing breeze and ditto weather.

At 11 30 saw land bearing N. N. W. supposed to be Tinhosa False.

 sail. 



At 2 a. m. 11 gale decreasing with less sea on.

The size of the typhoon of November 10th, appears to have been 150 to 160 

 miles in diameter. For, assuming the Swallow at 10 a. m. to have been near 

 the centre, the General Wood was about 70 to 80 miles distant on its northern 

 or north-western limit. We learn from Captain Burn, of the Atiet Rohoman, 

 that on the 10th November he was to the northward of Pulo Sapata, with light 

 S. E. winds and a very heavy sea from N. and Eastward ; so that, although the 

 wind did not affect the Atiet Rohoman, the strongly agitated sea affords evidence 

 that a disturbing influence was in operation to the N. and E. of the last men- 

 tioned vessel. 



The following notice, also from the above paper, is the only one I 

 have been able to obtain of the Ardaseer' s share of the Cyclone : — 



Since the above was in type, we learn that the Ardaseer, in her passage up 

 the China Sea, on Nov. 8th, when in Lat. 15° N. Long. 119° E. encountered a 

 severe typhoon which laid her on her beam ends, with all sails furled. The Ardaseer 

 on the 8th was six degrees to the Eastward of the Swallow, so that it would appear 

 the storm passed in the line of its track at the rate of about 200 miles in 24 hours. 

 The Ardaseer was proceeding Northward so as to run away from the storm ; had she 

 been passing to the S. or W. she would probably have suffered as severely as the 

 Swallow — Editor. 



Remarks. 



The Rob Roy does not appear to have had more than a fresh gale at 



Noon of the 7th, but at midnight we may consider her as fairly within 



the outer circles of the Cyclone, having the wind at N. N. W. and its 



centre therefore bearing from her E. N. E. She may have been at
