O'Reilly — On the Waste of the Coast of Ireland, ^c. 171 



(p. 27.) — " Since the great Glacial Period, but probably while 

 glaciers existed in at least some of the sheltered mountain valleys, the 

 sea rose at least 350 feet higher than it is at present, its waters chang- 

 ing the features of all the valleys that came under their influence 

 while at the same time and subsequently atmospheric waste modified 

 the higher portions of the country." 



(p. 39.) — '■'■ Inishark^ Inishgort, Inishkinnymore, and InishJcinny- 

 heg. — The first is the principal island in this group. It is bleak 

 and wild, rocky towards the west and north-west, while there is an 

 envelope of drift on the eastern slopes. At the north-west shore 

 are high and almost perpendicular cliffs. 



" Liishhofin has a general east and west strike. On an average it 

 is four miles long and two wide ; but the north and south coasts are 

 indented with bays and at Lough Bofin from sea to sea, is not half a 

 mile. The island consists of five hills, namely: — Westquarter, its 

 greatest height being 292 feet ; it forms a promontory nearly separate 

 from the rest of the island, being connected by the previously men- 

 tioned low isthmus in which Lough Bofin is situated : — Middlequarter, 

 highest peak, 288 feet ; Cloonamore, the north east hill, having a height 

 of 157 feet ; Knock, the hill east of the harboui-, 271 feet ; and Inish- 

 lyon, 143 feet, which is a tidal island, and separated from the other 

 hills during high water." 



(p. 42.) — "A little north-west of Lough Bofin are north 70° west 

 dykes, which apparently are portions of the gabbro dykes just men- 

 tioned. Further north-west and north-east of Bunnamillen Bay, are 

 massive dykes of melaphyre ; apparently portions of the same dykes, 

 but separated from one another, and shifted by faults. These have 

 weathered considerably and formed the deep marked fissui'es called 

 ' Eoher-na-coUig ' (Old hag's path)." 



(p. 42.) — " InisMurk lies about five miles north east of Bofin, and 

 eight miles from the mainland. The surface is undulating ; there are 

 four marked peaks : the north-west or signal tower hill, 629 feet ; the 

 north-east, 428 feet; the south-east, 588 feet ; and the south-west 240 

 feet. The east and south-east coast is low ; while on the west and 

 north-west are considerable clifPs, some of which are nearly perpen- 

 dicular and vary from 200 to 400 feet in height." 



(p. 43.) — " FreeMll mid Govern Islands. — These rocky islets lie 

 from one to two miles from the mainland and are composed of very 

 felspathic, massive, purplish and greenish grits and sandstones, often 

 pebbly and much cut up by quartz strings."
