272 Memoir on Indian Earthquakes. [No. 136. 



through which it passed. The obstacle in the path of the waters, 

 whatever its nature may have been, appears to have been wholly 

 removed at the end of twenty-five days, as then the temperature and 

 quantity of the water returned to its usual standard. 



Continuing to the Eastward of Delhi, the next place from which 

 intelligence was received relative to the effects of the shock, was 

 Poojnah, a station on the Doab Canal, (lat. 29° 32', long. 77° 27' ?) 

 where Sergeant and Assistant Overseer Renny observed and com- 

 municated to me the following detail : — 

 Extract of a letter from Sergt. Renny, dated Poojnah, 19th Feb. 1842. 



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

 an Earthquake here at — *. It lasted about three minutes with in- 

 tervals. 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 be- 

 lieve 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 this, I observed the 

 water in the canal was unusually muddy, and after the shock was over, 

 I went to look and found it much disturbed by a high swell, whether 

 occasioned by the shock or not, I cannot say." 



Sergt. Renny is entitled to my best thanks for these interesting de- 

 tails. The unusual muddiness of the canal could not possibly have 

 been due to the influence of the Earthquake, since the direction in 

 which the shock travelled was against, not coincident with that of the 

 current in the canal, hence the disturbance of the silt in the bed of the 

 canal could not precede the shock; but it is quite possible, that the high 

 swell observed after the shock had passed, may have been occasioned 

 by it. The time of the shock at Poojnah was, as nearly as I can 

 estimate it, Oh. 00m. 12s. p. m. Jellalabad time. 



From Poojnah, the shock travelled to Saharanpore, where it was 

 just felt, but attracted no particular attention. , It was next ex- 

 perienced at Kulsea, another station on the Doab Canal, about twelve 

 or fourteen miles to the Northward of Saharanpore, where its effects
