causes of Earthquakes, whether of terrestrial or atmospheric origin, are 

 in full activity, circumstances to which no analogy is presented at 

 Simla, since I am not aware of there being in the vicinity of that 

 place, one single proof of active volcanic agency. The question will 

 doubtless be farther elucidated ere the labours of the various magnetic 

 observatories are closed, but it is unnecessary to dwell longer upon it 

 now, as it will again come under notice at a subsequent period. 



The following table presents a general view of the course and phe- 

 nomena of the Jellalabad Earthquake, and with it, the account of this 

 remarkable event will be closed : —

2. Earthquake of the 5th March, 1842. 



On the evening of the 5th March, 1842, a very severe shock of an 

 Earthquake was experienced at several stations in the North Western 

 Provinces, about 9 o'clock p. m. Judging from its effects, it appears 

 to have emanated from the interior of the Himalaya, since the stations 

 in and near the hills were much more seriously affected than those at a 

 distance from them. Thus the effects of the Earthquake at Mussoorie, 

 (lat. 30° 30', long. 78° 10'), about 7,200 feet above the level of the 

 sea, were much more severe than at Saharan pore. In Major Aitchi-
