288 Memoir on Indian Earthquakes. [No. 136. 



In the Friend of India of the 17th Nov., it is stated in the weekly 

 summary of events, that on the evening of the I lth Nov. at about 

 9h. 50m. or 9h. 45m. by the town-clock, a very severe shock of an 

 Earthquake was experienced at Serampore. " It was accompanied by 

 a noise which at first resembled some "mighty rushing wind," and then 

 the loud rattling of carriages over a stony street. The shock came from 

 the Eastward : the clocks of which the pendulums vibrated from North 

 to South were stopped, while those which stood East and West con- 

 tinued going. So violent a shock has not been experienced in this 

 part of the country for the last twenty-five years. There was an un- 

 pleasant stillness in the air previous to this occurrence, but the wind 

 rose strongly from the Eastward almost immediately afterwards." 



In the Bengal Hurkaru of the 14th of Nov. the following details 

 are given: " On Friday the 11th instant, at about a quarter before 10 

 p. m. two severe shocks of an Earthquake were felt at Serampore. 

 They were preceded by a rumbling noise from the N. E. towards S. 

 W. ; the undulation was very great : all the houses at the place were 

 shaken, and those persons who had retired were obliged to jump out of 

 their beds, and some even quitted their houses, but through the mercy 

 of Providence, no injury was done. The Brahmans as usual were busy 

 with their shauncks and drums. The Earthquake lasted about four or 

 five seconds." 



In the other notices of the shock at Serampore which I have receiv- 

 ed, there are no new facts, so that I do not insert them. The time 

 stated above is, I believe, incorrect, and considerable difference of 

 opinion exists as to the duration of the shock. Such difference always 

 will exist, so long as mere sensation is made the measure of duration, 

 and proper instruments alone can remedy this imperfection. 



Darjeeling is situated within one minute Eastward of the meridian 

 of Calcutta, and I therefore give next, a notice of the shock as felt 

 there. For this I am indebted to Dr. A. Campbell.

" On the night of Friday the 11th instant, we had a shock of an 

 Earthquake at this place. Although not in bed or asleep at the time 

 it occurred, I was not conscious of it. Still it was, a smart shock, accord-
