374 Twelfth Memoir on the Law of Storms in India. [No. 161. 



near that at which the ships were wrecked on the inner Andamans as 

 marked ; which is a distance of about 140 miles in 36 hours, or from 

 noon of 10th to midnight 11th- 12th, and we can only estimate this 

 also on a direct line. Hence by noon of the 1 1th then, or in 24 hours, 

 it would then have travelled two-thirds of this distance, at which 

 point I have placed its centre for the 11th, which the reader will 

 observe is wholly irrespective of the supposed positions of the ships as 

 marked on their charts. I have made a dotted line to shew what may 

 have been their drift, if we have, as I presume, approached the true 

 place of the centre of the storm at noon on the 11th. 



The Petite Nancy, which on this day was opposite to the opening 

 between the Little Andaman and Nicobars, appears, though at 150 

 miles from the centre, as we have laid it down, to have felt some of 

 the effects of the storm, for we observe that with a NE. sea and squally 

 weather, her Barometer had fallen nearly an inch ! (0.96) in the 24 

 hours from the 10th. And that she had the rising and falling wind 

 which I have so often pointed out as indicating the approach or vicinity 

 of a storm. I defer the consideration of the storm which dismasted her 

 to its proper place in the order of time. Between 1 and 2 a.m. on the 

 12th, the Runnymede and Briton were both thrown high and dry 

 on shore on the inner Andamans, by a gale between ENE. and East; 

 and Captain Doutty of the Runnymede informs me that most of the 

 trees had fallen to the S. Westward, showing clearly that the centre 

 of the Hurricane had passed to the South of this spot. The storm 

 wave I shall presently consider ; but return now to the Royal Sovereign 

 on the opposite Coast. 



We find that within a short distance of the Islands fronting the coast, 

 on the 10th November, the Royal Sovereign had at 2 a.m. a heavy 

 gale at WNW. when the vessel was hove to, and at 4 a.m. she was 

 on her beam ends. At 11 it began to clear up, and noon was but a 

 strong gale and clear weather. 



Now from 2 am. to noon are 10 hours, and in this time a Steamer 

 in such weather, when hove to, might drift at least fifteen or twenty 

 miles to leeward, though keeping to with her steam; and the wind 

 being to the Northward of West she might drift out of the edge of the 

 storm circle, or as she seems afterwards to have steamed on to the NNW.
