Dewass to Ackberpore. No. 1 abounds in detached masses eight feet below the surface ; 



No. 2 in blocks four to six feet in diameter at the surface, and bedded two to three feet 



in No. 3, which latter is the prevailing stone at the pass, as far as the excavation has 



as yet been carried.

With reference to the three specimens of rock received with the foregoing letter, 

 read the following report from the Officiating Curator of 5th April, 1841, a copy 

 of which was communicated to the Government through Mr. Secretary Bushby : — 



'H. W. Torrens, Esq. 



1 Secretary, Asiatic Society. 

 'Sir, 



' 1 have to acknowledge receipt of the three specimens of Stone forwarded by Capt. 

 Kellner, through the Military Board, from the Pass at Ghurra Ghaut, and to say that 

 they are 

 '* No. 1. Hornblende Slate (or Basaltic Hornblende.) 



1 No. 2. Argillaceous Sandstone, with veins of mica, having a metallic appearance. 

 ' No. 3. Felspar Prophyry. 

 ' I beg to suggest, that if a good series of specimens through the whole line of 

 road, with a plan and elevation, and as many barometrical elevations of the heights 

 of passes, &c. as possible, could be procured, it would be a great addition to our 

 geological knowledge; as we have but very few sections crossing from the NNE. 

 to the SSW. from the valley of the Ganges towards that of the Nurbudda. 



1 1 further suggest, that a copy of Capt. Tremenheere's Memoir be sent to Capt. 

 i Kellner, and indeed to all officers in charge of road-making duties. The specimens 

 are for the present placed in the Museum of Economic Geology.

'H. PlDDINGTON, 



Qffg. Curator, As. Soc. Museum. 

 With reference to the 3rd paragraph of Mr. Bushby's letter, a question having 



been 



suggested as to the proprietorship of the Museum of Economic Geo- 

 logy, the Meeting were of opinion, that as it was not likely that the Government 

 would ever recall it, that the Asiatic Society be considered virtually the proprietor. 



* Specimen too small to determine to which variety belonging.
