that seems to attack lumps small of it, changing the outer surface to 

 the colour, grain, and consistence of chalk. This change is the more 

 remarkable in a rock, which like this is of a blue colour, and possessed 

 of considerable hardness. 



165. In the descent from Surara to the bed of the Syrij river, limestone 

 is the only rock seen, ascending thence to the ridge which forms the right 

 bank the same rock prevails of a less pure type, and occasionally of a 

 schistose structure. In the lateral glen in which the village of Ureea 

 is situated, the rock appears to be mica slate, or a transition between 

 that and clay slate ; the limestone is in general impure ; when otherwise, 

 it appears to undergo that superficial caries already noticed. It must 

 be rather an extensive bed, for most of the surrounding ridges were 

 also observed to be composed of this rock, as recognised in its charac- 

 teristic ledgy precipices. This limestone is also seen in the descent 

 to the Bangur, and also in the bed of that nullah, distinctly stratified 

 and dipping N. E., the reverse of the micaceous argillaceous schist 

 near Ureea, which is S. W. 



166. On ascending from the bed of the Bangur, an anomalous rock 

 is seen, in amorphous patches of a greenish colour and considerable 

 hardness, very possibly ferruginous quartz rock. A black type of the 

 same rock occurs in fragments in the bed of the nullah, and with 

 disseminated iron pyrites, (rhombohedral iron pyrites,) argillaceous 

 schist then establishes itself, being occasionally of a magnesian charac- 

 ter; occasionally (below Sookowlee,) of a micaceous. The route here 

 passes over the several ridges which ramify from the Chandpoor peak, 

 the rock of which is micaceous schist, and this line appears to be the 

 junction of the two formations, to judge by the frequent transitions and 

 oscillations. It may be observed, that the strata appeared pretty 

 regular, and with exception of the rock at Ureea, appeared to dip 

 conformably. 



167. In the vicinity of Sokanda, the schist assumes a micaceous 

 character. Near Dharee, limestone protrudes in limited quantity, and 

 we have then the argillaceous schist with its usual variableness of 

 character continuing to the bridge over the Tonse at Mywar. It is 

 at one time a blue smooth laminar slate, (talc argillaceous schist,) 

 again a fine grained slate approaching to compact (argillaceous schist,) 

 which is succeeded by a fine grained greywacke, slate (micaceous
