1036 Memoir on Indian Earthquakes. QNo. 144. 



noticed, 1 have not been fortunate enough to discover them. From 

 1831 to 1835, a register of the shocks felt at Lohooghat in Kamaon is 

 given in Dr. McClelland's Geological and Statistical Account of that 

 district. Judging from the direction of the larger portion of these 

 shocks, there can be little doubt of their having emanated from the 

 centre of the Himalayan chain, and to this source they are attributed 

 by Dr. McClelland. A few are doubtful, but in default of better 

 evidence, I have included these among the Earthquakes of the central 

 Himalayan region. 



Earthquake of the 25th December, 1831. — This shock occurred at 

 9 p. m. Its duration was about seven seconds, and its direction on a 

 North-west and South-east line. The motion of the earth was undu- 

 latory, and the intensity appears to have been slight. 



Earthquake of the 2nd July, 1832. — The period of this shock was 

 1 1 p. m. " During twelve seconds," Dr. McClelland states, " the earth 

 shook, or rather trembled, and afforded a noise which it is difficult to 

 describe, but which may be compared to the sound of a heavy but tran- 

 sient rush of water. The noise preceded and succeeded the motion about 

 three seconds." 



Earthquake of the \%th August, 1832. — Time of shock 7 a. m. The 

 earth trembled for about the space of five seconds : no peculiar con- 

 comitant circumstances were observed, except that the weather at the 

 time was hot and sultry. 



Earthquake of the 23rd September, 1832. — Time of shock 10 p. m. 

 The circumstances of this shock were in all respects similar to those of 

 the Earthquake of the 2nd July 1832. 



Earthquake of the 'SOth May, 1833. — The earth was found to shake 

 rather violently for about twelve seconds at 12 p. m. It was attended 

 with a noise like that already described. 



Earthquake of 4th January, 1835. — About 7 a. m. a slight shock 

 was felt which lasted from fifteen to twenty seconds, but the motion 

 of the Earth was very gentle, and seemed to be on a line between 

 North and South, accompanied by a noise as usual. 



Earthquake of the Wth January, 1835. — About 1^ a. m. a shock 

 which seemed to be in the direction of North-west, and more violent 

 than the one on the 4th took place, accompanied by a noise like dis- 

 tant thunder. The motion was tremulous : and in crossing the strata, 

 it seemed to affect one at a time. 



At this point Dr. McClelland's register terminates, and no further 

 shocks, to the best of my knowledge, are recorded until the year 1842, 

 when a few of those noted in my register for that year, may be assigned 

 to the tract now under examination. As all the circumstances ac- 

 companying these shocks are stated in detail in the register, it will be 

 necessary for me to do little more here than simply to state their dates. 



Earthquake of the 5th March, 1842. — Although no information re- 

 lative to this Earthquake has been obtained from any point farther in 

 the interior of the Himalayas than Simlah, it appears probable from 

 its direction, that it emanated from the central tract, and to this I have
