so that the gale was renewed with her at NNW. veering, as she was 

 close to the centre,* by 8 p.m. to SSW. and moderating at midnight 

 of this day, when she was about in Lat. 10° 20' N. and at noon on the 

 1 Ith it was fine. 



We see, first, by the chart that on the 9th, the Sovereign was only 

 abreast of the Seyers in 8° 30' N., and on the 10th the whole of 

 the ships, except the Fattel Hair, were at nearly two degrees distant 

 from her; the Runny mede, the nearest of them, being at 110 miles 

 off, and both the Runny mede and the Briton close to the centre of 

 their storms, with which therefore the Royal Sovereign's has no sort of 

 connection ; for if it had, it must have been a steady gale from WSW. 



It was then an independent (and perhaps an imperfectly formed) 

 vortex, and we have now to see whether it had any connection with 

 the double veering of the Fattel Hair's storm. 



This vessel, we have seen, hove to at 6 p.m. on the 9th, being then 

 about in Lat. 1 1° 20' N., Long. 96° 37' E.t with a gale at SSW., and 

 this, by the way, proves that up to that time the centre of the principal, 

 or great storm, had really travelled about West, as we formerly de- 

 duced. The storm was also probably expanding at this time. 



The Fattel Hair, gradually drifted up with the SSW. gale and sea, 

 so as at 1 a.m. or in 7 hours, when her drift might have been about 

 twenty-five miles North, to have the wind SE. and at noon on the 

 10th the wind was " coming round from East to due North!" with her 

 so that, as she could not be now near the centre of the principal {Briton 

 Dido and Runny mede' s Hurricane,) she had been overtaken by 

 another one, or another one had formed with her, for we can easily 

 conceive how a S. Easterly gale may by the effect of a new vortex 

 come round, as is here described. Her position on this day at 

 noon is not given, but I take it to have been — as she must have drifted 

 to the NW. West, and even WSW. with the winds given— about Lat. 

 12° 03' N. Long. 96° 19' E. and as she had the wind North or Nor- 

 therly at noon, she was moreover now to the Westward of the centre 



* Or it may be that it was only just forming, and interrupted on one side by the 

 neighbouring land ? The log extract sent me is not very clearly detailed, 



t This is deduced from her Latitude and Longitude at Noon, and her " keeping 

 away (which 1 take to have been about NNE.) 32 miles," before she hove to.
