Mr. Weaver on the 
to arise in part from simple inflection, or from lenticular masses 
composed of concentric lamellar concretions, which, being enveloped 
in the general body, and abrupted near the surface, present only 
sections to lour observation. If we could follow their limits with 
the eye, we should probably find the fact to be as now stated ; a 
view of the subject, which may tend to explain the apparent 
inflections and contortions of rocks in general ; and perhaps, the 
stratified structure in all its varieties may ultimately be considered 
as resulting from concretion on the large scale. Some observations 
in the subsequent part of this memoir may lead to the reconsider- 
ation of this question. We may also remark in this quarter, as 
well as in many other portions of the clay slate tract, that the out- 
goings of this rock, on the declivity of a hill, frequently present a 
dip directly opposite to that which it possesses at considerable depths 
from the surface ; an instance of which kind may be observed in 
the road from Kilcarrah bridge to Arklow, the clay slate at this 
place dipping at the outburst in the soil under a low angle to the 
north-west, and then forming a gently curved line, it gradually 
acquires in depth the usual south-easterly inclination : as if the 
outgoings of the strata had yielded or bent toward the lower side 
or declivity, from a want of support. 
§ 68. The left bank of the Ovoca is equally rich in beds 
analogous to those contained in the right bank, which appear in 
many parts of the noble demesne of Bally Arthur;* as in the road 
leading from Kilmagig to Ballycooleen, in the brow opposite to 
Knocknamohil point ; in the road winding from the valley to the 
mansion above, and at the octagon, where a prospect of singular 
splendour and beauty bursts suddenly upon the sight. Many of
