 O'Lappan, Lord of Cinel Enda, was sLaiu by Cinel Eoghain of the 

 Island,' i.e. Inishowen. Thus historical evidence concurs with that 

 derived fi'oni an iusioectiou of the physical conditions, that Inishowen 

 was actually an island up to within very recent times. The raised 

 beach referred to is in reality a representatire of that of Kilroot and 

 Lame, containing numerous worked flints, and of the 25-30 feet 

 raised beach of Scotland, in which several canoes and other works of 

 human art have been found." (See J. Geikie, " Great Ice Age," 

 p. 311, &c.) 



(p. 10.) — "The promontory of Inishowen, as now constituted, is 

 exceedingly hilly, and consists largely of rocky ground, covered by 

 heath and mountain bog. Its culminating point is Slieve Snaight 

 (= ' Snow llountain ' ), a quartzite mountain, which rises from the centre 

 of the promontoiy to an altitude of 2019 feet above Ordnance datum. 

 The most prominent featui'e is the grand quartzite ridge of Raghten 

 ^lore, which traverses the western portion of East Inishowen between 

 Dunree Head and PoUan Bay, and reaches an elevation of 1655 feet. 

 Thus, although of no very great elevation, this mountain ridge, owing 

 to its position as rising abruptly from the Atlantic, and breaking off 

 along its western slopes in a naked wall of quartzite, conveys to the 

 mind an impression of massiveness which is not altogether dependent 

 on its altitude." 



(p. 11.) — " The coast-line of Inishowen is generally rocky and 

 precipitous, except along the margin of Lough Foyle, and the inlets 

 through which the principal streams make their escape into the 

 ocean. The northern coast is particularly bold, the cliffs often rising 

 to heights of 500 or 600 feet, and at ' the Pounds,' north of Glengad 

 Head, to a height of 802 feet above Ordnance datum. Malin Head 

 (fig. 1), although the most projecting point of the coast is compar- 

 atively low (125 feet) ; but Dunaff Head, at the entrance of Lough 

 Swilly, presents to the Atlantic waves a bold wall of granite and 

 quartzite of over 600 feet in height." 



(p. 13.) — "Islands. — Several islands rising fi'om the Atlantic lie 

 at some distance off the coast of Inishowen. The largest of these is 

 Inishti'ahull (fig. 3), a rocky mass, nearly a mile across fi'om east to 

 west, formed chiefly of gneiss. Some dangerous rocks, called ' The 

 Tor Eocks ' (fig. 2), rise above the surface a mile north of Inishti-a- 

 huU ( = ' Island of the big strand ' ).
