CHAP. 3.] CONCLUSION. 287 
of the Vindhyan range of mountains to be seen among the KARNÜL 
rocks. Indeed in physical features perhaps the bottom beds of 
the lower group of the KADpAPAHs bear the strongest resemblance 
to the Kymores of the VINDHYANS. 
The order of IL of the groups of strata are somewhat 
different in the classifications of the two formations under comparison. 
In the KARNULS, the diamond-bearing series, or Banaganpilly quartzites, 
is always at the bottom; whereas the group of the VINDHYANS con- 
taining the diamond beds is a well-marked middle group. The clas- 
sifications are as follows in descending order :—

This difference in the order of the strata does not, however, after 
all, much affect the question, as it can hardly be expected that the 
same groups of rocks should always be lithologically the same in differ- 
ent parts of the country, or always associated with like subjacent beds. 
The Kymores—supposing that the KARNÜLS are Upper VINDHYANS— 
may not be represented in the Cuddapah area. 
The main feature of resemblance between the rocks of the Rewah 
country and those of Madras is, that there is a group of sandstones in 
each which is: alone characterised in each formation by the presence 
of diamond-bearing beds, though it now turns out that diamonds were
