near Palumbaddy to a point about a mile and a half north of Cullygoody. 

 Beyond this a few scattered patches occur of less 

 importance, only two of them being of such size 

 as can be shown on the map ; but, with one exception, in all pro- 

 bability originally connected with the main ridge, which must thus 

 have extended to a length of not less than 6 miles. The excep- 

 tional case, a patch between the villages of Aumarasure and Malarasure 

 is interesting, as it occurs on the gneiss at the distance of nearly a mile 

 from any of the older Cretaceous rocks, and affords the only instance of 

 the kind I have met with. 



Of the main ridge, that part immediately to the North of Cullygoody, 



shown in the accompanying figure (Fig. 5), is most 



clearly exposed, and that in which the peculiar 



characteristics of this singular formation are best to be studied. Its 



greatest width is about 250 yards, as roughly estimated by pacing. It 



?ises with a gentle slope from the gneiss, presenting a rugged surface of
