tween this and the violet clay band above, immediately over which the 

 nummulitic limestone comes in rather strongly, with an apparent 

 thickness of 50 to 75 feet, vertically bedded, but its cross section, as 

 is often the case, inaccessible for measurement. 



On the basal surface of one of its lower beds groups of stars, at 

 first looking like clusters of coral, were observed. On closer examin- 

 ation these were found to consist of a whitish mineral, in radiating 



prisms, some of which, on being tried by DrV 

 Mineral in limestone.

blowpipe. 



Beyond the limestone to the north the lower tertiary sandstones 



were seen to succeed it, and another rib of this limestone brought up 



by disturbance occurs among these further northward near Krunzeenai 



(Krunzinai).

 but above the opposite bank the distorted synclinal admitting the last 

 named beds was seen ; the section being confused here and there by 

 slippage of different portions of the rocks on the steeply sloping hill 

 side. See Fig. 50, which is a diagramatic sectional representation of 

 the rocks on right bank of Algud near Lakkona and of Muzdukkai hill 

 looking east.

Down in the ravine it is not clear how the beds are arranged, but
