76 KING: KADAPAH AND KARNUL FORMATIONS. [PART I1. 
A very peculiar bed or group of beds of limestone-breccia occurs 
in many parts (more particularly and distinctly 
to the southward) of the field close to the bottom 
of the Nerjee beds. "This is a grey, purple, or greenish limestone, very

compact and sub-crystalline ; but made up of a closely packed agglomera- 
tion of fragments of limestone (to all appearance just the same as that of 
the enclosing rock) which are rather oddly shaped. The fragments look 
like pieces of what was a thin-bedded limestone : they are long and thin 
and somewhat rounded, though at the same time showing often sharply . 
broken edges. They are confusedly jumbled together, not arranged 
in any order: and the rock looks more like a bed fractured and re- 
cemented i» situ, though it is inconceivable how such fracturing can have 
taken place without its having affected in some way or other at least 
the beds below; some of the specimens of rock look more like a veined 
limestone, but the unmistakably brecciated character is very soon seen 
in other parts of the seam. At one time the rock is uniformly very 
fine-grained, compact, and splintery, of a reddish-brown color, in which 
the fragments of which it is made up are easily recognizable. 
These are arranged together most closely, but quite irregularly, 
with only the thinnest walls of calcareous matter, of a lighter 
color than the rest of the rock, between the pieces. The thin walls 
are of cale-spar in minute crystals. There are necessarily some 
interspaces between the ends of the enclosed fragments, and these 
are filled up with compact limestone exactly like that of the frag- 
ments. In other cases the true brecciated character of the rock is not 
clearly seen: for the interspaces, though filled to a great extent with 
the same material as that of the fragments, or with cale-spar, are 
thinly charged with minute rounded fragments of quartz in various 
colors, in fact with sand. Such is more particularly the character of 
this seam to the north, about the Jeft bank of the Kistnah ; but further 
south, along the western scarps of the terrace below the Oopalpád plateau,
