220 OCCURRENCE OF GYPSUM IN THE 



Though I could not find the principal bed, I detected a small mass of an 

 irregular figure, enclosed in angular debris, which, from its impurity 

 and the freshness of its surface, had been, I conclude, formed in that 

 situation. The water of this stream is impregnated with sulphuretted 

 hydrogen. 



8. The third locality is on the ascent from the village of Rdjpur, 

 immediately below the hamlet of Jan Pant, situated in the range which 

 rises to the north of the Dun. It has been found, as yet, only in veins, 

 in a blue lime-stone, and chiefly of that variety called fibrous. Here, 

 too, as at both the other localities, the rocks develope, on being frac- 

 tured, a strong odor of sulphuretted hydrogen. How far this fact may be 

 connected with the origin of the mineral in these places, remains to be 

 determined. 



9. The strong family resemblance which the lime-stone rocks bore 

 in this place, to those in contact with the gypsum, at the former two local- 

 ities, was sufficient warrant of the actual existence of the mineral, in great- 

 er quantity, in the immediate neighbourhood. And I was afterwards for- 

 tunate enough to discover it not many miles from the spot where these 

 fragments had been picked up. This fourth locality is on the northern face 

 of the range, in the ascent from the hamlet of Ranon to the summit. 

 It is found in some quantity, and of the same character, and under 

 precisely the same relations, as at Sansar Dhard. The masses of 

 which there are several, are all superficial, and contain fragments of the 

 black fetid rock on which they lie, which also, like that at Sansar 

 Dhdid, though non-effervescent itself, passes into one that is — and 

 which also, when rubbed or struck, gives out the odor of sulphuretted 

 hydrogen.
