1851.] A Twentieth Memoir on the Law of Storms. 203 



The exact point at which the centre passed appears to have been 

 about midway between Balasore and Jellasore, at the Dantoon staging 

 Bungalow,* as described in Mr. Campbell's brief but valuable note, 

 which is a remarkable instance of how important even the briefest 

 common-sense narrative of the passage of these meteors may be to us. 

 Capt. Spens 5 more detailed and careful account of his observations in a 

 lonely sea-shore Bungalow, without any instruments, is another instance 

 to shew that great light may be often thrown upon questions of which 

 the observer may not perhaps think at the time, for his account, 

 with Mr. Baillie's, and that of Mr. Brackley in October, 1848, Jour. 

 Vol. XVIII. p. 849, aid us much to understand for the future the 

 terrific accounts of the inundations from the great storm Waves, when 

 their elevation, the time of tide, and the intensity of the Cyclone 

 are such that they are raised to their highest point. 



The centre at noon 27th must have been about Lat. 2 1° 45' N. Long. 

 87° 20' E. or a little to the W. N. W. of Jellasore, since it lulled for about 

 half an hour at 10 a. m. ; and thus the true centre at 10£ a. m. or in 

 22£ hours, had travelled up from its position on the 26th to the 

 Dantoon station, a distance of 218 miles or at the rate of 9.8 miles per 

 hour: though it seems latterly to have travelled at a greatly aug- 

 mented rate, for it was bearing about West of the station of Midnapore 

 at noon, or had travelled according to this estimate, something more 

 than 30 miles in an hour and three quarters. It is possible that this 

 increased velocity may have commenced after the irregularity at False 

 Point, to whatever cause that was owing. We must however, observe 

 here that the wind is stated also to have been due North at noon at 

 Bancoorah also, which station is 60 miles to the N. N. West of 

 Midnapore ; the fact being, as I have elsewhere shewn, that the mere 

 surface winds on shore, are but very indifferent guides for the position 

 of the centre. Midnapore has many irregularities of surface, but 

 Bancoorah has much more of these, and we cannot really say in what 

 direction the actual wind was blowing at the different stations. It is 

 only the calm centres which we can trust to for an accurate estimate 

 of the track of the Cyclone. 



28^ April. — We have no farther reports of this Cyclone beyond 



* Anglice — Traveller's cottage-house, at the stations where the palanquin 

 bearers are changed.
