All the beds, from the red sandstone to the uppermost sandstones, 

 appear to be conformable, but there is considerable confusion and 

 disturbance accompanying the salt-marl. The conformability of the 

 whole series is much more apparent in the eastern part of the Range 

 where the salt-marl is less developed. 



The lowest observable rock in the Salt Range is a vast deposit of 

 gypsum, gypseous red marl, and rock-salt| (No. 1), which may 

 be described as a red gypseous clay containing broken-up stratified 

 masses of gypsum and salt. Above this is a thick deposit of red sand- 

 stone (No. 2), its lower beds being schistose, and, near the salt, 

 alternating with dark red clays. The sandstone frequently contains 

 bands of grit and conglomerate, chiefly of small boulders of 

 metamorphic rocks. It is of little thickness towards the Indus, but it 

 increases in force to the eastward, and in some places it is not less 

 than 400 feet thick. Above the sandstone is a small series of 

 coarse, bluisb, arenaceous shales and micaceous sandstone (No. 3), 

 tinged green with chlorite, and often presenting carbonaceous, but 



* The Belemnites and Ammonites of which Dr. A. Fleming has sent specimens 

 are " Oxfordian " forms ; i. e. of the same formation of Oolite or Jura as is known 

 in Russia, Cutch, and the Himalaya.

+ At some places masses of red sandstone and conglomerate appear at the foot 

 of the southern flank of the Salt Range, but these are not inferior to the salt and 

 gypsum (as at first sight they sometimes appear to be, and indeed as they were 

 described to be in Dr. Fleming's first letter and in his Reports referred to above), 

 but are deranged beds and out of their place.
