1869.] The Mineralogical Besources of Ireland. 507 



As regards the remaining useful metals, it is only necessary to 

 mention that ores of lead, zinc, copper, silver, and native gold 

 occur in various parts of the country, especially in the counties of 

 Wicklow, Waterford, Tipperary, Monaghan, Kerry, Galway, Dublin, 

 Donegal, Cork, and Clare. We have only to cast our eyes over the 

 catalogue of localities where mines, or metaUiferous veins have 

 been discovered, published by the General Valuation Office, under 

 the superintendence of Sir Richard Griffith, to be assured that the 

 country is rich in minerals, only partially developed. Beds of 

 rock-salt have been recently discovered near Carrickfergus, and 

 gypsum near Kingscourt, in county Meath. Nor in this brief 

 summary of the mineral resources of Ireland may we omit to 

 mention — the encrinital marbles of Galway, Cork, and Dubhn ; the 

 granites of Wicklow, Down, and Galway ; and the rich serpentinous 

 marbles of Connemara.*
