recently been built, and was being finished, fell in, but luckily it did no 

 injury to any one living in the house." 



It will be observed, that the writers of these interesting letters 

 differ at least an hour and a half, or two hours in their estimates of the 

 time at which the shock was felt at Kawulsur, the first placing it 

 between 10 and 11 a. m., the other at noon. By comparing the 

 periods of the occurrence at stations farther removed from the focus of 

 disturbance, as at Delhi, Poojnah on the Doab Canal, Saharunpore, and 

 other places, to which more specific reference will immediately be made, 

 I am disposed to consider the first of these estimates as the most 

 correct, and to fix the period of the shock at Kawulsur at very little 

 after 10 a. m. 



Travelling in an easterly direction, the next notices we have of the 

 Earthquake is its being felt at Delhi, where its period appears from all 

 accounts to have been about 10 minutes past 11 a. m. On reaching 

 Delhi, both the intensity of the shock, and the rate of propagation 

 of the undulations seem to have materially diminished ; and beyond 

 the motion of the ground, no other effects are alluded to. 



Still continuing easterly, and in a direction very little removed 

 from a right line between the two places, the shock travelled from Delhi 

 to Poojnah, a station on the Doab Canal, where its effects were observed 

 by Serjeant and Assistant Overseer J. R. Renny, and the following 

 details connected with them were forwarded by him to me. 



Extract of a Letter from Serjeant Renny, dated Poojnah, \9th 

 February, 1842. 



" I also beg leave to inform you, that we felt a very severe shock of 

 an Earthquake here at about half-past 11 a. m„ it lasted about three 

 minutes with intervals. My whole family felt it, as well as the people 

 about my place, who came running to me much alarmed. It was 

 first noticed, I believe by myself, as I was then sitting writing, and 

 found a heavy table on which my desk was laid, much agitated, which 

 I thought was caused by some one moving, but I soon found my 

 chair in motion also, and on looking about, I perceived every thing 

 moveable in the room in a state of agitation. A few hours before
