4. This would give but 46.8 per cent, of metallic iron in this ore, but 

 no doubt a better chosen specimen from a deeper bed or a deeper part of 

 the same bed might equal that of Burdwan. In Bohemia where this ore 

 occurs largely it is much prized. The report of our bazar people* quite 

 confirms Mr. Samuells' account of the good qualities of the iron. 



5. No. 2, Paleyra ore. 



This ore is a mixture of the hydrated carbonate of the protoxide of 

 iron, with a large proportion of earthy matter. On calcination, it changes 

 from a very dull greyish red to a bright chocolate red. 



It contains in 100 parts 



Water, • 9.76 



Earthy silicates, , 27.20 



Protoxide iron, 60.60 



Ox. manganese, 2.10 



99.66 

 Loss, . . .34 



100.00 



6. This amount of protoxide of iron represents 47 per cent, of metallic 

 iron, and from the presence of the manganese, it would probably be of a 

 good quality. 



7. As connected with the great interest which iron ores and their 

 fluxes and smeltings have at this time, I beg to annex to the present 

 report a paper just drawn up by me for the Journal of the Asiatic Society 

 which already shews that the problem of the smelting and fluxes (if the 

 kunkurs can be found in sufficient quantity) has long been practically 

 solved by Mr. Taylor of Burdwan. 



I have the honor to be, Sir, 



Your obedient servant,

Coal from Thayet Myo, Pegu. — I reported last year, Journal Vol XXIII. 

 p. 714, on specimens of coal brought from Ava by Capt. iNiblett of the 

 Sesostris, which was brought to Rangoon by the Burmese from fields 

 beyond the British territory. Since that time as is now well known, coal 

 has been discovered at Thayet Myo within the British boundary. I ob- 

 tained a specimen of this coal through the kindness of Captain Niblett of 



* And as they do not import iron their opinions are unbiassed.
