40 A Twentieth Memoir on the Law of Storms, [No. 8. 



tremendous rate; 9 a. m. Bar. 29.50; blowing a heavy gale from S. E. to 

 S. S. E. with tremendous hard squalls and rain. Noon Bar. 29.54, a hard gale 

 from S. S. W. the clouds over head fast clearing away; 3.30 p. m. much more 

 moderate, Bar. 29.60 ; 8 p. m. hard monsoon breeze from S. S. W.; Bar. 29.67. 



The following notice was inserted by me in the Calcutta Englishman 

 of Saturday, 27th April. 



We had a heavy, oppressive, calm day on Friday, which had much the 

 feeling of an approaching Cyclone, but the Barometer still remained high, so 

 that all which could be said was, that if one existed in the Bay it was only 

 coming towards us. This morning however a little after midnight the wind rose 

 in squalls, with rain from the North East, and then gradually increased in 

 strength till 10 a. m., when the wind, which was North East, and at times N. E. 

 b. E. with squalls at daylight, had veered to East and E. b. S., and at noon it 

 was E. S. E. still blowing and raining in smart and heavy squalls, showing 

 that the Cyclone had not passed far from us, but was already to the Westward 

 of our meridian. The remarkable part of this Cyclone, however, is that the 

 Barometer has scarcely fallen, having only been at 29.77 at 9 a. m. ; and still 

 more remarkable, the Simpiesometer has been always higher than the Barometer 

 by .02 or .03 up to Noon, when we are writing for our evening paper with the 

 Barometer at 29.64 ; Thermometer 82 J. From all this we should infer that a 

 Cyclone of small extent, but of considerable violence, has passed upon a track 

 from about E. S. E. to W. N. W., or say from Akyab to about Hidgellee, 

 near which place, or to Point Palmiras, its centre has probably passed. We 

 shall look with much anxiety for the accounts from Kedgeree and Balasore 

 during the next week, as well as to those from Midnapore; for to judge of the 

 track by the strong Southerly squalls up to 4 p. m., the Cyclone has probably 

 curved up towards Midnapore and Bancoorah in the latter part of its course. 



Calcutta. 



The following are my own notes at Calcutta, they are far less perfect 

 than I could have wished them to be, but I was obliged to be absent 

 from home on public duty, and was otherwise indispensably engaged 

 during the whole day.* 



* I wish it indeed to be understood that these memoirs, and the whole of my la- 

 bours in this branch of science, are the fruits of a careful economy of my few leisure 

 hours and often of privations of sleep and of due recreation. And this will perhaps 

 explain to those who would desire them more perfect why, though fully conscious of 

 their imperfections, I have been unable to render them more complete, and investi- 

 gate at greater length, and by experiments and serial observations, many questions 

 which are yet obscure. I have no time myself, and I have not the means to employ 

 an assistant.
