Our indefatigable correspondent, Captain Shortrede, sends us a specimen of a 

 supposed Lithographic Stone, of which his account is as follows: — 



To H. Piddington, Esq. Curator Museum Economic Geology, Calcutta. 



Sir, — I have the honor to inform you, that I have despatched to your address for the 

 Museum of Economic Geology, by the Steamer Luckia, a package containing a slab of 

 Stone from the neighbourhood of Rewa, which I apprehend may be found useful for 

 Lithographic purposes. 



I have sent two pieces ; the smaller of which may serve as a hand specimen, and the 

 larger for Lithographic experiment. 



There are some quartzy veins which probably may render this particular slab of no 

 great value, but if the stone be otherwise fit for Lithography, it seems desirable to 

 bring it to notice.
