286 Memoir on Indian Earthquakes. [No. 136. 



tion, from the swinging of pendulums, was from about E. N. E. to W. 

 S. W. If I hear any thing more, I shall not fail to note it for you, and 

 I add at bottom a copy of our note made at the meeting. I was acting 

 as Secretary for Mr. Torrens, and it did not occur to me to examine 

 the Barometer; but I found no difference afterwards at home, and a 

 friend who has an excellent simpiesometer assures me, that no effect 

 was produced upon it, he having examined it immediately afterwards, 

 so that in slight shocks the atmosphere seems to have no share. 



Yours very faithfully, 



H. Piddington. 



The note alluded to above by Mr. Piddington, as having been made 



at the meeting of the Asiatic Society, is as follows: " At * the 



proceedings of the Society were interrupted by two or three slight ver- 

 tical shakes or heaves of the Earth, with a noise like the rumbling of a 

 passing carriage, and one strong horizontal shake from East to West, or 

 from N. E. to S. W. The whole took place within about a minute of 

 time." (Signed) H. T. Prinsep, President. 



The following extract from a letter from J. McClelland, Esq., gives 

 some further details of interest, and shews that the Barometer was 

 seriously affected during the shock : " With regard to the Earthquake 

 of the 1 1th November, the only information I am able to give you that 

 has not appeared in the Calcutta papers is, that the mercury rose and 

 fell repeatedly, to the extent of seven or eight tenths of an inch during 

 the shocks in a Barometer on the second floor of St. Xavier's College, 

 a house in Chowringhee. The inmates of which house also describe 

 the water in a large pond, of about three hundred yards in length and 

 seventy in breadth, extending lengthways North and South, to have 

 risen into considerable waves. This was also the case with the River, 

 which appeared agitated, as if a steamer had passed. This refers to 

 the river at the Botanic Gardens, where it is not half so broad as it is 

 at Calcutta. A clock in the house of the Superintendent of the 

 Garden, which had gone regularly for years, stopped suddenly during 

 the shock. I observed three distinct shocks, they seemed to me to be 

 rather a tremulous motion than a waving in any one direction ; but 



* Time omitted as erroneous.
