close to the bog edge, and appears to underlie an extensive bog, 
situated to the east. The whole country westward is calcareous 
slate, and the nearest dip to this is eastward, towards and under 
the limestone, which is a mile off. 
Carlingford, in the county of Louth, is a pretty large town on the 
south side of Carlingford Bay. Limestone is extensively quarried 
near the town, and contains fine specimens of fossils; Siphonophyl- 
lia cylindrical Bellerophon apertus , $'C., are common. The lime¬ 
stone here is near the junction with the greenstone of Car¬ 
lingford mountain, and is penetrated with numerous trap 
dykes, some cutting across others, and showing dykes of three 
separate epochs. Near the junction, the limestone is in some 
places highly crystalline, white in colour, and contains large, 
rudely formed garnets. 
Carn, in Fermanagh, is three miles S.E. of Kesh, on the east side 
of Lough Erne. The rock here is all limestone, and contains 
fossils. 
Carrickboy, in Longford, is five miles N.E. of Ballymahon, and 
about five miles S.W. of Edgworthstown. The limestone here 
is light gray, and very fossiliferous. 
Carrickduff, in Longford, is two miles north ofGranard. 
Carrickoughter, in Fermanagh, is two miles N.W. of Kesh; it is 
situated in the limestones, shales, and sandstones of this neigh¬ 
bourhood, which lie low in the formation. 
Carrigahorig, in Tipperary, is three miles S.E. of Portumna. A 
deep cutting for a mill-race has been made here through the 
rock, which leaves it well exposed. The colour is light gray, 
and it is very fossiliferous. Univalves , such as Nautilus , Euom- 
phalus , &c., are common, and they come well out of the rock. 
Carrigaline, in the county of Cork, is six miles S.E. of Cork; light 
gray limestone similar to that of the Cork valley occurs here, and 
contains fossils. 
Carrowmably, in Sligo, is four miles S.E. of Easky on the sea¬ 
shore. 
Carrowmacrory, in Sligo, is six miles east of Easky, on the sea¬ 
shore. The rock here is impure limestone, and fossiliferous.
