14 BALL : GEOLOGY OF THE RAJMEHAL HILLS. 



He describes the hitherto undiscovered coal of the Chuperbhita pass 

 and some seams in the neighbourhood of the known localities both on 

 the north and south, regarding which latter, too, he gives some addi- 

 tional information accompanied by sections. 



The important iron beds on the south-east of the area are briefly- 

 described. The paper concludes with an account of thirteen coal seams 

 which were all that were known to exist in the hills at the end of 1851. 



In the Calcutta Review there is a very interesting account

 XVI, 1861. tions." Some passing allusions are made in it 



to the geological structure.
