Report of the Curator Museum of Economic Geology for the month of 



April, 1853. 



Geology and Mineralogy. — Dr. Cantor has presented us with a specimen 

 of Fossiliferous limestone from Girbee in the Straits of Malacca of which 

 the following is his memorandum. 



1. Fossiliferous limestone and lignite from Girbee. The late Captain 

 Congalton, H. C. Steamer Diana proceeded in July, 1845 to Girbee 

 river, on the Malayan Peninsula in 8° 0' JN". L. On his return to Pinang 

 he communicated to me a diagram and memorandum of the locality 

 in which the lignite occurs. 



Tamah is a hillock about 11 ft. high above the strata. 



Length of the strata from 300 to 400 ft. their diameter from 1 to 14 

 inches, those of the greatest diameter below the seam of lignite, and they 

 deviate from the upper strata at an angle of 4 to 5°. In the ironstone 

 nearest Datoo Putri appears a cave, nearly circular, about 20 ft. in 

 diameter, but of no great depth. Round the cave radiate short strata, 4 

 to 5 ft. in length, of fossiliferous limestone like the strata below Tamah, 

 Tanjong Datoo Putri is a limestone rock, not stratified, about 500 ft. 

 above low water mark, and about a mile distant from the hillock Tamah. 



The seam of lignite runs nearly horizontally from east to west. The 

 eastern extremity is 2 inches in depth, the western 8 inches. The 

 shells of the strata appear to belong to the genera Paludina and Melania, 

 and closely resemble recent species inhabiting the Malayan Peninsula 

 and Islands. 



Economic Geology.- — The following report relates to the specimen of 

 copper ore from the Barragunda mines in the Hazareebagh district, now 

 on the table, which was examined at the request of Mr. Mackenzie. This 

 gentleman informs me that the mine has anciently been worked to a very 

 great extent under the native governments, but that they only worked one
