4g SKETCH OF THE 



would appear to distinguish the rock in question from the rocks of that 

 formation, and all things considered, I feel inclined to believe that it is 

 a lias — or, at least a formation nearly allied to the lias. Its position 

 leads me to draw this conclusion, and there is nothing either in its 

 structure, mode of occurrence, or organic reynains, to militate against such a 

 supposition. The Pec ten is a shell of the lias, though certainly not a 

 characteristic one. 



The formation I have just described never rises into hills, but is some- 

 times seen occupying gentle elevations : the surface of the country 

 where it occurs having a waved aspect. At Cheelore, the strata of this 

 rock are much disturbed, and in other situations I have seen similar 

 appearances. 



We shall now proceed to describe very briefly another rock which 

 occurs in the belt under consideration ; viz. the quartzose breccia, before 

 alluded to, and to which Captain Dangerfield has applied the name of 

 hornstone. This belt exhibits numerous low rounded hills, hill groups 

 and ranges, — some of the last of considerable extent, more especially the 

 one which forms the boundary of Meywar and Harowtee. These hills 

 do not rise higher than three hundred feet above the level of the plain, 

 and the majority of them average below this height. Their upper por- 

 tion is formed of this quartzose breccia, which rests immediately on the 

 sandstones, sandstone slates, &c,, which rocks form the base, and very 

 generally the central regions of these hills and hill ranges. This brec- 

 cia I have never seen in low situations, or resting on the limestones. 

 The shape of the hills is sometimes conical. This is particularly the 

 case with detached hills and groups, but the ranges generally exhibit an 

 even and uniform appearance, and the summit is occupied by a table land, 

 or a gently waved plain. Some of the detached hills also present this
