185 J.] Report on the Copper Ores of the Deoghur Mines. 3 



4. In April, 1849, Mr. Vincent forwarded specimens and reported 

 the circumstance of the existence of the copper ore to the Magistrate 

 of Beerbhoom, but no notice has been taken of his report. 



5. The nearest coal to the spot is at Kurkurbali, 40 miles S. W. 

 in Pergunnah Kurruckdiha in Zillah Hazareebagh ; coal is also found 

 57 miles in a South-easterly direction in the Rajmuhal hills. 



6. Believing this to be a valuable discovery I lose no time in bring- 

 ing it to your notice in the hope that you will bring it to the notice of 

 Government ; any further information relative to the spot or roads lead- 

 ing to it will be cheerfully supplied upon application being made to me. 



(Signed) W. S. Sherwill. 



It may be proper, especially in reference to certain insinuations, 

 which I refrain from qualifying, made at the July meeting of the 

 Asiatic Society regarding the Museum of Economic Geology, to pre- 

 face this report with the following letter ; to explain alike the nature 

 of the researches of which this paper contains the results, and the 

 reasons why some notice of them was not earlier given. It may yet 

 be, as every scientific Geologist and Mineralogist will understand, that 

 the discoveries announced in it are connected with great questions of 

 public revenue and unknown resources which we possess in India, and 

 in the due execution of the trust imposed upon me as a servant of 

 Government, it was necessary that the information this letter conveys 

 should be in the hands of Government at the earliest period. Those who 

 are acquainted with the difficulties of researches of this kind in India, 

 and who feel with me what is due to the high standing of the Society's 

 Journal will I trust find that nothing has been lost by a little delay. 

 Secret Service. 

 From H. Piddington, Curator Museum Economic Geology. 

 To Seton Karr, Esq., Under Secy, to the Government of Bengal. 



Sir, — I am greatly averse to making any incomplete report on 

 scientific matters, but learning from some conversation with Captain 

 Thuillier that much speculation has been excited by the reports which 

 were published by Government a short time ago regarding the recently 

 discovered Deoghur Copper mines, and that some applications have been 

 or will be made to Government on the subject of them, I deem it right 

 (though I originally intended to wait as I shall subsequently explain, 

 until I could complete my investigation) to make the present report 5
