914 Fourteenth Memoir on the Law of Storms in India. [No. 168. 



Forbes' storm was clear of the coast, and that at Cananore it was a 

 gale on the 3rd, from 8 a. m. to 1 p. m. from NE., East, and SE., and 

 that the ship Charlotte had no bad weather on the coast, being between 

 Cochin and Cananore till the 4th ; showing that this Cananore storm 

 was of very small extent, and that the Cochin storm also did not 

 reach much beyond that latitude. It is therefore more probable if 

 the Rajasthans storm came from the coast, that it was the Charles 

 Forbes' travelling up in a NW. direction. Of the probability of this as 

 to time and distance, we shall be better able to judge, when we have 

 fixed the position of the Rajasthans storm. That of the Monarch, 

 which Captain Stewart supposes to have been the same, was evidently 

 a different one, preceding that of the Rajasthan by fully eighteen hours. 



It appears that on the 4th at 4 p. m., Ca*ptain Stewart observed 

 a sudden fall of the barometer and sympiesometer, and that by noon of 

 the 5th, the wind had increased to such a degree from the N W. that he 

 judged it prudent to heave to, considering himself, as he observes in his 

 note, in the South-western quadrant of a circular storm, which he no 

 doubt was, and, from the sudden shifts, not far from the centre. I 

 have therefore assigned it a circle of eighty miles in diameter only, 

 which will allow her to have been twenty-five miles from the centre at 

 noon, and in so small a vortex this seems quite a sufficient allowance. 

 I am indeed inclined to consider this storm as one which was of much 

 greater extent above, than at the earth's surface, thus affecting the ba- 

 rometer from 4 p. m. of the 4th ; but not of any great violence, since the 

 ship was running on, though her Captain clearly understood his posi- 

 tion, till 6 a. m. The circumstance of the barometer remaining so 

 low, with gusts at times though the force of the wind had, as it proved, 

 passed over, is an additional motive for our supposing that the vortex 

 may have been of much greater extent above. 



The Monarch's hurricane as I have remarked, was evidently earlier 

 in time, though this ship was considerably to the N. Westward of the 

 Rajasthan. 



It is remarkable that the Monarch seems to have seen the vortex spread- 

 ing overhead at 10 p. m. on the 3rd, when her sympiesometer began to fall, 

 and in three hours by 1 a. m. on the 4th, she had it blowing a complete 

 hurricane, and at noon on that day she was at the centre of it. She 

 laid to till 8 a. m. of the morning of the 5th, (the day of the Rajasthan' s
