326 Museum of Economic Geology of India. [No. 124. 



V. 



Native Metallurgical Processes, or Mineral Manufactures. 



1. Exact descriptions of them, however rude or simple they may appear, with 

 samples of the ores, fuel, fluxes, products, slags, &c. 



2 Models or drawings (to scale if possible) of the furnaces and implements of all 

 kinds ; specimens of these last may be sent. 



3. Memoranda and samples of the earths or sands used for moulds in castings, of the 

 crucibles and beds, raw and baked, and of the raw material from which made. 



4. Prices of raw and wrought materials. 



5. Drawings of machinery used for turning, boring, polishing, &c. 



In conclusion : It is not supposed that any individual, unless wholly devoted to 

 the research, can supply the whole of the desired specimens, or even of the knowledge 

 relative to any one product; but any single item of the foregoing may be of import- 

 ance, at sometime, to some one ; and it will be the special duty of the Asiatic Society, 

 and of the Curator of the Museum, to see justice done to every contribution; whether 

 relating to the Geology of India in general, or to this peculiar branch of it.
