232 Temperature of the hot springs at Peer Mungul. [Aug. 



almost black ; on adding a few crystals of Barytes to another glass 

 full, the water in which was perfectly clear, it at once became like 

 milk and water, but shortly after it settled, a considerable white deposit 

 falling to the bottom of the glass. On addition of a little potass to 

 another glass of water, a few minute bubbles of air or gas escaped from 

 the crystal, but eventually the water became slightly turbid, and on clear- 

 ing, a slight white deposit, but very slight indeed, on the bottom of the 

 glass, but I had no means of weighing the deposits, and have since lost 

 them. The high range of rocks in their vicinity are a kind of soft 

 limestone, at least the parts exposed to the weather and air are soft and 

 white, almost like chalk, but with small crystals of I think sulphur in it. 

 The lower range or rather ridge is coarse sandstone, capped with lime ; 

 the strata in some parts is almost perpendicular, and in others curved. I 

 scrambled up to the top, the view from which was most curious, a jumble 

 of hills of all sizes, shapes and colours ; the lower ones, apparently full of 

 beds of gypsum, as the continuation of them beyond the Lukkee pass, 

 which I examined, was full of that substance. Nasseer Khan attempted 

 to work the sulphur here, but found it a loosing speculation owing, I 

 fancy, to his not having descended deep enough, through the blue marl at 

 the base of ridge.
