1843.] Ninth Memoir on the Law of Storms in India. 805 



in fact was the time at which he was nearest to the centre, and ending, 

 as it should do, at South when it had passed on. At Cuttack they 

 had by noon on the 2d an increasing gale North and N. N. E. ; by 4 

 p. m. strong gale North,* with furious squalls, and this continuing 

 with little variations till 3 a. m. of the 3d, when a lull took place, 

 followed by a change to E S. E. and S. E. The strength of the gale, 

 says Dr. Minto, was from noon till sun-set of the 2d, while it was 

 moderating with the ships as before remarked. 



Having thus described, briefly, the weather experienced on these two 

 tracks, it may be useful to shew by a comparative table, that they could 

 not be the same storm ; for at first sight, one is inclined to take them as 

 such, and the fact of two severe hurricanes at once, of small diameters 

 travelling with great rapidity on nearly parallel lines is a new acquisi- 

 tion to our storm knowledge, and will serve perhaps not only in future 

 to explain many phenomena which are not now well understood, but to 

 guide the perplexed seaman with comparative safety, as I shall in the 

 sequel shew. It is evident, however, that our first care is to prove, that 

 the phenomena about which we reason did really occur. We have 

 already shewn this, and I think with a tolerable degree of certainty; 

 but the negative proof will also greatly assist our views. Not forgetting 

 my remarks on the Eliza's position as possibly twenty miles too far to the 

 South, let us now see how the ships Eliza, Halifax Packet, and 

 Emerald Isle, were situated during their storms; what were the winds 

 and weather they had ; and what were those that they ought to have had 

 if they were all in the same storm ; and to the ships we will also add 

 the winds and weather at Cuttack and Pooree, beginning from mid- 

 night between the 1st and 2nd October, which is the earliest time at 

 which it was felt by the Eliza. 



The Eliza at this time was about in latitude 18° 30', longitude 

 89°, and the storm had then fully begun with her from the N. N. E. 



Now if all the Ships were in one storm, —
