they consist of duplicates put aside for your Society, in the course of the new arrange- 

 ment, now in progress, of our Collection. Still some of them will, 1 think, be of in- 

 terest, if not in the higher and scientific department of your Collection, at least in that 

 of Economic Geology. The specimens of the Bombay Basalt, I request may be 

 presented in my own name, and if more specimens of the Minerals they contain are 

 required, I shall endeavour to procure them. 

 Another case will be dispatched in a few weeks. I have the honor to be, Sir, 



Your most obedient servant,

List of Specimens forwarded. 

 No. I to 6. Specimens of iron ore from Malwan, in the Collectorate of Rutna- 

 gherry. See Journal of the Bombay Branch Royal Asiatic Society, 

 No. Ill, and Geological Transactions, Vol. V, page 548. The rock 

 in which this fine ore is found, is stated to be sandstone, I think 

 by mistake. 



— 7 ,, 9. Building stone from the ruins of Mandoo, the Ancient capital of 



Malwa. The fine reddish sandstone abounds with minute corals, 

 and I have also found in it marine shells. Many of the finest 

 buildings are composed of this. 



— ,,10. Selenite. Persian Gulf ? 



— ,, 11. Lithographic limestone (so called) ; southern Mahratta country. See 



Capt. Jervis' and Capt. Newbold's Papers in Journal of Asiatic 

 Society of Bengal, Dr. T. Christie, in Edinburgh Journal of 

 Science, and Geological Transactions, Vol. V, plate 46. 



— ,, 12. Argillaceous limestone. South Mahratta country. 



— ,, 13. Common ditto, (Kullajee,) ditto. 



— ,, 14. Calc spar in argillaceous limestone, ditto. 



— ,, 15. Limestone, ditto, 



— 16 ,, 17. Diamond sandstone, near Belgaum, ditto. It is not known that dia- 



monds are found in this rock. It is so called from its relations and 

 mineralogical characters being that of the diamond matrix. 



— ,, 18. Diamond sandstone. Kowlgere, Dharwar S. M. country, 



— ,, 19. Laterite, ditto. 



— 20 „ 21. Gypsum from Persian Gulf. This was imported in some quantity 



intended to be used as stucco. 



— 22 „ 25. Rock of which the Maldive Islands are formed, collected by Capt. 



Moresby, I. N. See Darwin on Coral Reefs. The complete col- 

 lection in the Bombay Museum is perhaps unequalled. 



— ,, 26. Iron stone from Segoor, 15 miles north of Dharwai*, South Mahratta 



country. 



— ,, 27. Iron ore used at the native foundries, Mahableshwur hills. 



— „ 28. Painted plaster of the baths of Aurungzeebe's palace, Aurungabad, 



by J. G. Malcolmson, Esq. 



— 29 ,,30. Granite from bed of Nerbudda near Mhysur. See Major Stirling's 



letter, Bombay Geographical Society's Journal. This granite rises 

 in the middle of the basalt, and is cut by basaltic dykes.
