The limestone now rises rapidly on both sides of the river, (see 
fig. 1, pi. 25) and shows beds corresponding in colour under N and 
H\ the dark green clay again issues from beneath it, at k and / : at 
the former place its beds are much bent, and are of considerable 
hardness ; large fragments of it are seen in the river amongst the 
boulders. Here are found in great numbers the nodules of fetid 
limestone, as on the Pulcovca, also crystallized sulphuret of iron in 
flattish masses. Below this, the blue clay appears for a short space, 
at i and j ; to which succeeds the green clay dipping again in a 
contrary direction at g and 5, and though so lately in great strength 
(considering the ordinary weakness of this bed) at k, is now only 
traced by a strong line of dark green, accompanying a flesh-coloured 
or reddish yellow clay, as it sinks on both sides of the river under the 
limestone at g and h. This is the only spot where the junctions of 
the three strata have been discovered in the same cliff, the blue clay 
but seldom appearing under the green. The limestone now is seen 
forming the high cliff at A , and containing one thin clayey bed of 
white and red, very like the colours shewn by the inferior blue 
day on the Cuzminka and Solticovca. It is also seen on the right 
bank, shewing the back of its different beds, dipping considerably to 
the north-east. To this succeeds alluvial rubbish for some distance, 
till at L the blue clay again appears, and is continued without 
interruption, (except from alluvial accumulations) on the banks and 
in the bed of the river, ’till it enters the plain below Pulcova. The 
limestone thus, at first sight, appears to have dipped under the blue 
clay, or (supposing any mistake could exist as to the dip of such 
turning the corner of the promontory, II. Therefore there is nothing improbable in sup- 
posing that this was their original position. Then let that part of the central mass which is 
next the dyke?/, sink from want of support, and the part which joins the dyke x will 
naturally incline upwards towards it.
