Wynne — Notes on the Geology of the Punjab Salt Mange. 93 



having usually a soft matrix and intensely hard metamorphic 

 pebbles and boulders. They are found just at the upper surface of 

 the salt marl in the west part of the range, and at one or two other 

 stages before being again largly developed in the lower part of the 

 Olive group, which contains the Conularia-layer, apparently at a 

 slightly higher horizon. There is no known source for any of the 

 various metaphoric rocks to be found in these boulder-beds, includ- 

 ing a red granite which would be easily recognized either among 

 the Himalayan or Afghan mountains, if it existed in any force, so 

 that here again an old metamorphic region, lying to the southward, 

 suggests itself as forming land at various periods during the long 

 record of the Salt Range rocks. Whether this may have formed, 

 or not, a portion of the lost continent, Lemuria, supposed to have 

 at one time united Africa with India, it is not for me to say ; but 

 failing the future discovery of similar forms or others of similar 

 age in the hitherto azoic beds of the older portion of the Salt Range 

 series, I am disposed to think these pebbles must have come from 

 lands and rocks long since buried beneath the country southwards 

 of the Salt Range, now oocupied by the arid plains and deserts 

 which lie in this direction.
