taking the opposite sides of Muzdukkai hill. From the general ar- 

 rangement of the beds both of these bands appear to have filled the 

 interiors of anticlinal curves, the positions of which were altered by 

 lateral pressure and their ordinary relations obscured by faults.

the very frequent constrictions of the gorges as they traverse the num- 

 mulitic limestone occurs, leaving, indeed, no visible passage except that 

 for the water of the stream through the vertical wall of limestone. A 

 precarious footing may, however, in one place be found overhanging the 

 deep pool below, around which the rocks are all exposed. 



Here some beds of the limestone are most strangely placed, the t

The band of limestone marked (c) continues up the right bank of 

 the ravine, but seems to have thinned away on the left bank ; the inter- 

 mediate reddish purple clays and sandstones apparently thin out to the 

 east, but contain calcareous layers (a) and {b) } which as well as (c) con- 

 tain nummulites, the upper band (c) being of a gnarled, lumpy, mixed, 

 sandy, and limestone nature. 



The mass of the limestone at the waterfall is locally thin and of 



Magnesian limestone the hard ^eolina variety, and the red clay zone 

 associated with gypsum. an( j gyp SUm come in immediately behind it. 

 Over the surface of this gypsum small fragments of magnesian lime- 

 stone layers evidently associated with it were observed, and the lime- 

 stone was seen again edging the southern side of the gypsum.
