1845.] Twelfth Memoir on the Law of Storms in India. 373 



Eastward of her, and had it also blowing a hurricane from about South, 

 judging from the log abstract, in which it is made to be SW, at 1. a.m. or 

 after midnight up to Noon, and South at 2h. 30' p.m. The Dido whose 

 exact position this day I could not obtain, has a hurricane at SE. being 

 in the NE, quadrant. The hurricane had thus no doubt extended on 

 this day from a circle of 60 miles to one of 1 30, and apparently was 

 still doing so, for the Fattel Hair, farther to the Eastward than 

 the Runnymede, seems to have ran up skirting the SE. quadrant of 

 the storm and to have had the true storm wind at SW. when it 

 " shifted at 2 p.m." to that point. The Royal Sovereign, close in with 

 the land, appears to have also had a separate small storm veering 

 with her in a few hours, but not of any very great consequence, or at 

 all connected with the Briton's and Runnymede' s ; though, as I 

 shall subsequently shew, it may probably have been so with the 

 remarkable double veering of the Fattel Hair's winds. On the 

 11th we have the above two ships always lying to and drift- 

 ing, as well as they could estimate in the hurricane, to the points 

 marked on the charts, which are about forty miles NNW. and 

 SSE. of each other, but there is no doubt that the ships saw 

 each other at 2 p.m. on this day; the Runnymede also saw a brig, 

 but this was not the Dido, which vessel had her foremast standing, 

 and was not at this time in the heart of the hurricane.* We shall 

 also find that the two ships Briton and Runnymede struck just after 

 midnight of the lith-12th, (or between 1 and 2 in the morning 

 of the 1 2th) so that they must have been now much farther to the 

 Eastward than they supposed themselves. We have no fixed positions 

 of any other ships also from which to guide us as to the extent of the 

 hurricane circle on this day, and in short our only datum is that both 

 ships having the wind to the Eastward, i. e. the Briton between NE. 

 and ESE. and the Runnymede about SE., both must have finally 

 drifted over to the Northern quadrants of the hurricane, though al- 

 ways close to its centre. 



We must then therefore consider that (throwing away the odd hour 

 or two after midnight of the 11th- 12th) the hurricane travelled, and 

 carried the ships with it from the place of our centre on the 10th, to 



* Probably one of the native coasting craft which run across the Bay to the ports of 

 the Straits.
