rent, — the ship's own run or drift &c— to induce these irregularities; 

 and we find that as the centre passed on and she fell into the S. Eastern 

 quadrant of the storm, she again experienced it blowing a hurricane 

 from S. W. shewing that (as she had run a little to the North) she had 

 been on the Southern side of the central space; of whatever extent this 

 was. It is indeed I think most probable that on this day she was not 

 to the Northward but the Southward of the Mary Imrie's position. 

 Both ships were probably very near to, though they did not see. each 

 other. The Vernon's position gives a radius of 110 miles, Or a diame- 

 ter of 220, for this storm for this day, and we are satisfied that it could 

 not be the Niagara's or Fyzulbarry's, the Niagara being evidently 

 close to the centre of hers. I shall remark on the 2nd, on the Madras 

 and Ceylon reports for this and the next day. 



On the 2nd December. — We find that the Mary Imrie on this day 

 while running down say about 80 miles* to the South and South East- 

 ward, before a terrific hurricane veering from the N.N.E. to the N. West- 

 ward, had her Bar. always falling, and was at 2 a. m. in another, and of 

 course a different centre from that of the Candahar's storm of the day 

 proceding, for she was now perhaps 100 miles from that ship, This centre 

 gave her another hurricane at S. S. W. and Capt. Boyd's description 

 of the sea is exactly what we should suppose the effect of a second storm 

 passing over any part of the sea left by one just preceding it to be. I 

 think it most probable that this second hurricane may have been the 

 Niagara and Fyzulbarry's storm and have so marked it ; supposing the 

 Mary Imrie to have been in Lat. 9° 20' and Long. 85° 00' and the 

 centre a little to the Westward of her. 



The Candahar, on this day had run to the North and N. W. round 

 the Eastern and North Eastern quadrants of her storm, while the Ver- 

 non, which ship had stood to the E. S. E. with the N. Easterly gale of 

 the preceding day, had a smart shift of wind of four points, as the 

 centre approached her, and a fall of 0.14 in her Bar. As the storm 

 however passed to the South of her, and she was bound to the North- 

 ward, she was soon out of its influence. We find also on this day that 

 a Westerly and N. Westerly storm prevailed at the stations on the 

 North end of Ceylon. To obviate confusion, I have preferred consi- 



* We must take this by guess having no log of the distance.
