276 Memoir on Indian Earthquakes. [No. 136. 



son's Meteorological Journal, the following details of the shock are 

 given : — 



" 5th March. Thermometer at sunrise 62°, wind East. Thermo- 

 meter at sunset 58°, wind as in the morning, weather clear. At ten 

 minutes past 9 P. m. a most violent shock of an Earthquake, which 

 lasted about a minute Colonel Young's house at Deyrah was much 

 injured, also Major Thompson's at Mussoorie, and Lord Henry Gor- 

 don's at Landour was rent from top to bottom," Venetian blinds also 

 rattled strongly, lamp glasses were violently shaken, and the oscilla- 

 tions causing these effects appear to have come from North to South. 



The motion of the Earth from all accounts appears to have been 

 horizontal, and the nature of the shock was wholly distinct from that of 

 the preceding Earthquake ; all who experienced both assuring me, the 

 difference was perceptible to them at once. The effect in the present 

 instance, instead of being like the rounded swell of a fluid or viscid 

 mass, was sharp and sudden, like the effect of a concussion than of an 

 undulation, and seemed indeed to be a much magnified " jarr," similar 

 in kind to that experienced by the hand when a hammer held by it is 

 struck on a hard unyielding body. One intelligent friend who was in 

 his study when the shock occurred, described his sensations to be, as if 

 he and his chair had received a sudden and severe blow from behind, 

 and been both ; impelled forward, and this appears to have been the 

 characteristic of the shock. 



The following interesting details of the Earthquake as experienced 

 at Berkeri on the Doab Canal, were communicated to me by Sergt. and 

 Overseer J. Petrie, to whom I feel much obliged for his trouble in 

 preparing them : — 



Letter from Sergt. J. Petrie to my address, dated 5th March, 1842. 



Sir, — We had a very smart shock of an Earthquake here this 

 evening at about 9 o'clock : so much so indeed, that every thing in this 

 bungalow shook and rattled again. I had just laid down to rest with 

 a book in my hand when it came on, and I started up and called out 

 for assistance, thinking the house was coming down. Every one about 

 the place felt it, and came running to me. I found the South door of 

 the inner room, which I had bolted before I went to bed, had been 

 forced open by the bolt falling down. Indeed every thing in the house
