about 100 feet to 300 feet thick, stretching along the hills for 70 or 80 

 miles ; their Southern extension, in the Ramghur Hills, not being above 

 50 miles distant from Raniganj. 



There is nothing improbable in the conglomerates of Panchet, 

 Beharinath, &c, being an extension of these beds. In mineral character 

 they are similar. But it is possible that, being isolated and only slightly 

 unfossiliferous, their affinities may never be satisfactorily determined. 



So far as can be at present predicated, the following conveys briefly 

 the probable relations of the beds of Eaniganj, Orissa, Rajmahal, Cen- 

 tral India, and Nagpur.
