Geological Relations of the Hast of Ireland . 267 
rocks commonly occupy more elevated ground than the adjacent 
limestone. 
§ 167. The county of Wexford is almost as destitute of lime- 
stone as that of Wicklow, and contains only three detached patches 
of that mineral. One occurs at Kerlogue, one mile south of Wex- 
ford, forming a low narrow slip which follows the coast for four 
or five miles to the southward, being hounded principally by quartz 
rock to the west and north. The limestone strata dip mostly at an 
angle of 15° to 20° toward the south, and consist of bluish grey 
limestone including corallites and bivalves, and associated with a 
brownish grey, fine granular, magnesian limestone. 
At Duncormack is a second small district of limestone, which 
extends from the coast into the interior, for three or four miles in 
a north-east direction, toward Scarbridge and Brideswelf, and to 
the north toward Taghmon. It is, mostly bounded by clay slate 
and quartz rock, except on the south-west, where it comes in 
contact with sandstone conglomerate. This limestone is generally 
of a reddish brown cast, seemingly derived from the conglomerate 
in its vicinity. 
Hook Point, the southern extremity of the county, consists, as 
already stated, (§ 146) of limestone resting on the red sandstone 
and sandstone conglomerate. 
% 168. The association of the floetz limestone with brownspar 
has been noticed by the late Mr. Tighe in his Statistical Survey of 
the county of Kilkenny;* and by Mr. Richard Griffith, junior, in 
his valuable tract on the Castlecomer coal district,']' to which works 
I beg leave to refer, not having myself had an opportunity of ex- 
amining the places where that association is to be observed.
