KiNAHAN — On Some of the Irish Crystalline Iron Ores. 317 



adjoining the intrusions of the Carboniferous (?) granite; which 

 may indicate that these outbursts and the lode are of similar age. 



Descriptions of other places in Ireland where these iron ores 

 were worked would be little more than repetitions of what has 

 already been said, as we could only mention of the county of Clare, 

 that there were formerly extensive mines there ; some, such as those 

 of Ballymalone and Bealkelly, being on cakes of ore, like those 

 in the county of Wexford — Cambro-silurians ; and of the counties 

 of Longford, Roscommon, Fermanagh and Tyrone, that the iron- 

 workings there are in the Carboniferous Limestone, &c., &c. ; that 

 the old workings are now inaccessible, while the new lodes have 

 not been sufficiently investigated to afford much information. We 

 may, however, mention that at Knocksnaghty, county of Clare, and 

 in other places, graphite, associated with iron, occurs in true veins.
