352 Report on the Geologieal Structure of the Salt Mange. [No. 4« 



of a very different appearance from that of the Salt Eange, as form- 

 ing the surface rock at least of several of the Hazara hills north of 

 Eawul Pindee and on the mount Mochpoor. About fifteen miles 

 north of the new Murree Sanatarium, which attains an elevation of 

 upwards of nine thousand and seven hundred feet, we obtained abun- 

 dance of nummulite limestone on its sides and summit. 



From Cashmere too, Mr. Yigne obtained limestone containing 

 nummulites. This we have seen in situ on the side of a mountain 

 at the upper end of the Manasabul lake, where it is much disturb- 

 ed and calcined by greenstone. It probably forms the summit of 

 many of the higher hills on the northern side of the Cashmere val- 

 ley, a district fraught with interest to the Geologist, and hitherto 

 quite unexplored. 



"When we consider that the nummulite formation may be traced 

 from the Mediterranean through Egypt, Asia Minor and Persia 

 into the north-west and southern provinces of British India, and 

 throughout all this extent preserves the same zoological character, 

 though differing considerably in mineral aspect, the importance at- 

 taching " to a right understanding of its true position in the Geologi- 

 cal series," cannot be overrated.* 



* Since writing the above, we have had the pleasure of perusing the anniversary- 

 address, for 1852, of the President* of the Royal Geographical Society, in which it 

 is stated, on the authority of Professor Oldham, that " the coal and iron of the 

 district of Cheera Punjee, or the range of hills which separates Assam and the 

 Beramputer from the plains of Sylhet, belong to the nummulite tertiary formation." 

 We may also state that from specimens of the coal and rocks connected with it, 

 which were forwarded for our inspection from the Singrowlee coal mines near Mir- 

 zapore, in December, 1849, by Claude Hamilton, Esq. one of the proprietors, we 

 gave our opinion that it was a coal of a similar character and of a similar age, 

 with that of the nummulitic formation of the Salt Range. This coal is now pretty 

 extensively consumed by the Ganges Steamers, and is sold at Mirzapore at the rate 

 of 75 Rs. per hundred maunds. A sample of this coal, which we analyzed in Sep- 

 tember 1850, gave the following results. 



Carbon (coke), 43.34 



Volatile, bituminous inflammable matter, 50.00 



Ashes, 6.66 



Total 100.00
