1843.] Memoir on Indian Earthquakes. 269 



I have also frequently found the conglomerate overlying the slate, and 

 they are frequently united in the same rock. The conglomerate is 

 very hard, and we could not progress more than four inches an hour, 

 with two-inch jumpers, in boring holes for blasting. The stones seem 

 cemented with a sort of iron cement." 



After leaving Peshawur, the shock traversing the alluvial plains of 

 the Punjaub reached Ferozepore, (lat. 30° 56' 50" ; long. 74° 35',) where 

 its force was still felt to be severe, though no longer destructive. No 

 accounts have been made public of the effects of the shock at any 

 place intermediate between Peshawur and Ferozepore. The latter 

 place was reached at llh. 48m. 40s. a. m. Jellalabad time. 



The city of Delhi, (lat. 28° 40' ; long. 77° 16',) is the next place from 

 which we have authentic intelligence of the effects of the Earthquake. 

 The intensity of the shock was, however, very much diminished here, and 

 beyond the motion of the ground no other effects are alluded to. The 

 period of the Earthquake at Delhi, as stated in my notes formerly 

 published, I find to be erroneous, and the proper time from the best 

 information I have been able to procure, is llh. 53m. 56s. a. m. Jel- 

 lalabad time. Relative to the nature of the shock at Delhi, Mr. Sub- 

 Conductor Bingham of the Sappers and Miners thus writes : " The total 

 duration of the shock, which appeared to me to consist of several 

 distinct undulations of the earth, but without perceptible intervals 

 between them, could not have been less than five or six minutes. But 

 of this I cannot speak definitely, as I had no reference to a time-piece 

 during the shock." 



About twenty miles to the South-west of the city of Delhi, at a 

 village called Sonub, is situated a hot spring, of which the following 

 description is given anonymously in the second volume of the Glean- 

 ings in Science, p. 34 : — 



" At Sonub near Delhi, there is a hot spring (sulphureous) which 

 attracts from the surrounding country myriads of people for the pur- 

 pose of bathing; the bath is constantly filled with as many people 

 as it can hold, (except perhaps for a few hours during the night,) in 

 the day time by men, and the night time by women ; most of the inhabi- 

 tants of the town itself are in the habit of bathing in it daily, and it is 

 perhaps to this habit, that they are indebted for the cadaverous and
