Mr. Weaver on the 
range from the continuous part of the district on the north-east. 
The first, next to Cashel, presents limestone on the south-eastern 
side, conformably supporting shale and sandstone on the north- 
west. The second consists of limestone in the north-western and 
south-eastern quarters, but the mass resting upon it seems to be 
mostly shale, containing some nodules of clay ironstone. The third 
is limestone, with a south-eastern flank of sandstone, and probably 
some shale also. 
A fourth hill, on which stands New Park, and which borders the 
small limestone valley below, appears to be wholly composed of 
limestone. 
§ 201. The limestone around the Killenaule coal district is in 
general bluish grey, or tinged with black, and free from foreign 
beds, containing only occasionally lydian stone and horjistone. It 
is arranged in strata, one, two, and three feet thick, in which entro- 
chites are particularly abundant.

§ 202. That the ocean has been universally diffused over the 
surface of the globe, no naturalist at present denies. The great 
point in dispute is, whether the land has been raised from beneath 
to its present elevation above the water, or the water depressed to 
its present level below the land. Into this controversy I do not 
mean to enter.* But it seems impossible to consider the form of 
* I confess, however, my disbelief of a certain expansive power from beneath, to whose 
operation some philosophers have ascribed the position of the elevated strata of the globe, 
and have thence described them as lifted , or tilted. The phenomena recorded in the 
preceding pages alone, are, to my apprehension, a sufficient refutation of this hypothesis 5
