1. Limestone, KARNUL. g. Quartzite, KADAPAH. 
Again, the next succeeding ridge has limestones under the quartz- 
ites at the southern end, and limestones over the quartzites, further 
north on both sides of the ridge. 
Further north again, opposite Ketavaram, there is an altogether 
new feature in the relations of the rocks, for limestones, apparently of 
the same series as those to the south along the western bases of the 
ridges, are here overlaid by an immense thickness of slates with several 
bands of quartzites which make up the great Pulichinta ridge. And to all 
appearance this great mass of slates and quartzites stretches up north | 
north-east, and overlies the limestones south of Batavole or Jugguiapett, 
which at this point are greatly thinner than they are under the slates, 
&c., opposite Ketavaram if the lie of the beds between Ketavaram and 
the north-west boundary be taken as the true succession. 
In the quartzite ridges of the south-eastern angle of the Palnád, 
the limestones still hade under the quartzites; while, on the other 
hand, the limestones of the southern edge of the field he up over the 
quartzites of the Waumyconda range. 
These sections would seem to indicate that if we accept the lime- 
stones as all referable to one series, then it is hardly 
Considerations on this

It is tolerably certain that there are represent-
