RESEARCHES AMONG THE PALAEOZOIC ROCKS OF IRELAND. 145 
which some beds of purple slate are interstratified; and this slate 
contains Silurian fossils. They are got in the cliffs on the shore? 
in some accessible spots; and about high-water mark, some beds of 
reddish limestone show marks of them also. In the Red Sandstone, 
on the top of the hill, is a remarkable mass of white quartz, forming 
a crest, which at a distance resembles an old castle. 
63. At Glenteenassig, in the Dingle district also, immediately 
west of Loughnascall, is a magnificent exhibition of the lower con¬ 
glomerate, in a precipice above 100 feet high, lying on the upturned 
edges of the beds of a brown micaceous flaggy grit, belonging to the 
lower formation, as at Kinard. The conglomerate here is about 80 
feet thick. The strike of the two rocks is nearly the same; but 
the lower dips N. W., at an angle of 65°, while the upper dips at an 
angle of 25°. To the geological tourist this place is well worth a 
visit. 
64. Doon Hill, near the latter locality, has a cap of conglomerate 
dipping N. W. about 30°. The junction with the underlying rock 
is not visible. The nearest part of it to the place is seen in stream 
a little eastward, where very thick beds of a chloritic greenish gray 
grit rock are visible, dipping W, at an angle of 65°. 
67. At Quarter town upper, near Mallow, there is a junction of 
the brownstone and Old Red Sandstone. It was exposed when the 
railroad was in progress of being made; but since has been much 
obscured by what the engineers call “soiling the slopes.” The 
brownstone south of this junction presents the usual physical as¬ 
pect it does in the south of Ireland, hard and strong-bedded, the beds 
a little undulating, with an average dip S. E. The Old Red, which 
dips N. E., or towards Mallow, at about 20°, consists of a soft red 
rock below, succeeded by a little bluish gray shale containing Mo - 
diola cypricardia, &c., and over this a yellow sandstone which dis¬ 
appears northward under the drift. 
68. At Waterford, and its vicinity, the lower beds of the Old 
Red Sandstone are well exposed on the hill at Newrath, as well as 
on the west side of the river, opposite the railway station. The un- 
conformability here is very clear. Proceeding northwards from this 
place by Mullinavat, the conglomerate is succeeded by red beds, 
which, towards Thomastown in the upper part, as usual, are yellow, 
and covered there by the limestone of Kilkenny. At Kiltorkan, near 
Ballyhale in this line, are a few beds of very fine-grained yellow rock,
