9. Dark earthy soil coloured by a mixture of deutoxide and peroxide 

 of iron. 



10. Sandstone grit coloured by iron. 



11. Plastic clay, contains protoxide of iron. 



12. Same as No. 11 in thin laminae. 



13. A coarse-grained pegmatite, (i. e. quartz and felspar) decomposing. 

 N. B. There is a very singular-looking cellular, brittle, black substance 



in very small quantity adhering firmly to the outer part of this specimen. 

 There is too little of it to sacrifice except for minute assays : I should like 

 to have more of this. 



14. Granite and not a Syenite : the black mineral being black mica and 

 not hornblende ; there is, however, embedded in this specimen some minute 

 nests of Actinolite or pumice. They are too small to admit of examina- 

 tion, but I should like to have a larger specimen or two of this granite 

 if procurable.

 H. Piddington, Esq. 



My dear Sie, — May I request the favour of your furnishing me at your 

 convenience with an analysis of the accompanying specimen of ore, and 

 with your opinion of its economical value under the following circum- 

 stances. The deposit of which this is a specimen is from the Hill of 

 Karana, about ten miles from Lahore and not far removed from extensive 

 jungle of firewood ; coal in limited quantities is believed to exist in two 

 localities of which one is hundred miles, and the other fifty miles distant 

 from the site of the ore. Will you do me the favour to return the specimens 

 when you have taken off what you require for the purpose of analysis. 



Your's faithfully, 

 (Signed) W. E. Baker. 

 And having sent him an analysis and reply to his queries. I have subse- 

 quently received the following memorandum, by Mr. Purdon, from Colonel 

 Napier.

About the centre of the Siteh Chuj Doab, twenty-three miles South- 

 East of Shahpore, rise abruptly a number of conical-shaped knolls ; the 

 highest, and principal, called Karana, attains an elevation of about 1200 

 feet above the plain. This hill occupies an area from West to East in
