1843.] Memoir on Indian Earthquakes. 291 



The following letter published in the Bengal Hurkaru, gives an 

 account of the Earthquake as experienced at Barrisaul : — 



" As I dare say that the shock of Earthquake which was felt here 

 will have been likewise experienced at other stations with more or less 

 severity, accounts of which will doubtless be communicated to you, I 

 lose no time in telling you now, that a very severe shock was felt at 

 a quarter to 10 p. m. at this station yesterday (Nov. 1 1th) ; although no 

 accident occurred, considerable anxiety was caused by the length of 

 time the Earthquake lasted. The heaving of the ground appeared to 

 travel from E. to W. and continued with violence for about one minute. 

 The river was greatly agitated, so much so, that the serangs of several 

 pinnaces came on shore, unable to account for the extraordinary 

 motion of the water. 



" I send down this account, because I imagine that an Earthquake of 

 such severity having been felt at a place where its occurrence is so 

 unusual must have extended elsewhere, and all information on the sub- 

 ject may prove interesting. 



" P.S. — The weather for the last few days has been remarkably warm 

 for the season of the year ; the variation in the Barometer has not 

 been great. The Earthquake was accompanied by a rumbling noise, 

 similar to that caused by heavy ordnance passing over the ground." 



AtGowahatti, Assam, (lat. 26° 00', long. 90° 40' E.) the shock was 

 felt very slightly. Its period there was lOh. 00m. 56s. C. T. A cor- 

 respondent of the Friend of India describes the motion as merely 

 tremulous, but sufficient to attract the attention of four persons who 

 were seated together at the time. 



The shock was felt more severely at Chittagong, (lat. 22° 22' N. 

 long. 91° 42' E.) probably because it had to traverse only alluvial 

 lands, and had no mountainous tracts, as in Assam, to decrease its force. 

 The period as given by two tolerably correct clocks, was 9h. 42m. 48s. 

 C. T. The direction of the oscillation was from North to South, as 

 determined by the motion of hanging lamps, &c. 



The only place at any distance to the westward of Calcutta, whence 

 any notice of the shock having been felt has reached me, was Monghyr 

 (lat. 25° 02' N. long. 86° 29' E.) where a portion of the fort wall 

 is said to have been brought down. No farther particulars have come 

 under my observation, and I am unable to state either the time or direc-
