1842.] A Seventh Memoir on the Law of Storms in India. 1083 



tradicted in too many ways for us to admit it. For, first, if we 

 say that the storm was moving at the rate we have estimated, 5.3 

 miles per hour, and that the calm lasted at Calcutta, at the most 

 from lh, 30m. p. m. to 3h. 30m. p. m., or two hours, this would give, 

 say, 11 miles for the diameter of the calm space; and that it was not 

 more, is corroborated by the fact, that, to the southward, the Barque 

 Fairlie, at Hooghly Point, 25 miles to the SS. Westward of Cal- 

 cutta, and at the towns of Chandernagore and Chinsurah, 17 and 20 

 miles to the northward, no mention* is made of any calm interval ; so 

 that our estimate of 11 miles for the utmost breadth of the centre is 

 not far wrong. Again, to the Southward of Hoogly Point, to Kedgeree 

 and Saugor, which are about the same distance from Calcutta, in 

 that direction, that Midnapore is to the W. b S., no calm took place. 

 We are thus obliged to allow, that at Midnapore, there was a separate 

 vortex of small extent, for it appears by Mr. Homfray's report, that it 

 was not felt along the valley of the Subunreeka, which he says, 

 averages about 40 miles to the Southward of that stations.t 



And this fact again precludes our considering it as any relic of the 

 Cauvery's storm just described, even if the interval of time, and the 

 want of any trace inland of this storm, did not also wholly make 

 this supposition improbable. The interval of time is from the 31st 

 at midnight, when the Cauvery, then about 100 miles to the S. S. E. 

 of False Point, had a hurricane at North, the centre of it being 

 not far to the Eastward of her, to about 2 p. m. on the 3d, or 62 hours ; 

 and the distance from the estimated place of the centre to Midnapore, 

 would not be more than 240 miles. Midnapore also bears about 

 North a little Westerly from this supposed centre. To have reached 

 that station, the storm must have travelled about on a North course up 

 between the Light and Pilot Vessels and Balasore, and passed close to 

 Kedgeree. Not only there is no trace of this at Kedgeree, but the veer- 

 ing of the wind, from North to a hurricane at N. N. W. and ending 

 at West, must have been that of a storm travelling from the S. E. 



* Mr. Earle, in his excellent account of the storm at Garden Reach, see p. 996, men- 

 tions no calm; but that, from a hurricane at about N. b.W. it became "blowing pretty 

 fresh at N. W." before it again blew a hurricane from S. W. and W.S.W. He was 

 only 4 or 5 miles from Government House. 



t Speaking no doubt of the road distance. I find that by Mr. Tassin's map it ave- 

 rages about 30 only.
