In the above synopsis the term coarse implies fragments at least 4 inches 
long; the term medium-grained, fragments up to half an inch long; and 
fine, fragments less than half an inch in length. 
C(15). This series of red sandstones, with conglomeratic ashy 
and shaly layers, forms the greater part of Doon Point, and extends 
into the cove of Foilnamahagh to the north. Its lower layers show 
signs of disturbance, while the sandstones with shales and ashes 
(C16), upon which it rests, show much crushing and veining. 
Below comes a green rock (C 17), probably including both rhyolite 
and ash. It is very amygdaloidal in places, and much decomposed ; 
it 1s faulted against 
C (18), a coarse labradorite-porphyrite, which occupies part of 
Fig. 15.—Section across the inlets of Coosglass and Foilnamahagh.

the head of Foilnamahagh, and extends across the little point to the 
next cove on the north. ‘This rock is unlike any other met with in 
the Clogher-Head district, and in hand-specimens resembles the 
coarsely porphyritic rock which occurs associated with the Bala Beds 
of Kildare, Lambay Island, and Portraine. As a whole, the rock is 
coarse-grained and amygdaloidal in Foilnamahagh, while in the cove
