of January. 



Economic Geology. 

 I have taken advantage in the course of my correspondence on storm 

 matters with H. E. the late Naval Commander-in-chief, to request the favour 

 of specimens of coal and coal strata from Laboan, and of any other speci- 

 mens which could be obtained for the Museum ; and we have now received 

 from Captain Wallage of H. C. Steamer Nemesis, the following note with 

 a box of specimens and the sketch therein alluded to. 



Dear Sir, — A short time ago I received an order to make a collection of 

 strata, &c. from Laboan for the Museum of Economic Geology of India. 



I have now the pleasure of sending per Brig " Poppy" some specimens 

 from the north end of Laboan and adjacent islands, and a sketch of the 

 section of the same. 



Your's very truly, 

 (Signed) — Wallage, Commr.

The coal from Laboan I have analysed ; it is of a very fine description, and 

 in fact equal to the average of English coal, as given in Mr. Prinsep's table ;
