35. These several varieties of limestone, viz. shaly and sandy, and blue 
with white lines, repeat themselves continually as far as the top of the hill, 
but the rock becomes more and more massive and presents portions of crinoid 
stems well preserved and petrified into a black spar. Sometimes the rock ig 
flesh-coloured, and then the crinoid stems are lighter in colour, and weather in 
relief on the surface of the rock. These are the sections of crinoid stems which 
have been taken for nummulites by Mr. Vigne and Dr. A. Fleming. 150 ft. 
The strike of the beds of limestone wheels more and more toa N. to S. 
direction. As we approach the volcanic rocks of the Safapoor, the dip becom- 
jng more and more westerly. This wheeling of the strike is well shown by 
the Sketch-Section (Sect. F), where we see the face of the limestone-courses 
mncovered and exposed, and facing the W. N. W. The thickness of the Weean 
bed is altogether 649 ft. 
A large fault, well marked by a deep ravine, separates the limestone from the 
volcanic rocks. It runs N. E.—S. W. At the highest point the limestone is 
seen to attain, the fault is a mere crack, and the limestone is in contact with 
the volcanic rocks ; butt the S. W. end of the fault, it widens considerably, 
and beds of limestone are to be observed on its northern side, applied against 
the trap and conformable and superior to it. The trap dips 8. S. H. 
On the western face of the Safapoor, long beds of well-stratified laterite 
and ash are conspicuous; they dip 8. with an angle of 40. 
54, Oursection runs through the spur of limestone nearest to 
the lake; three other spurs, parallel to it, descend towards the
