1. On the Metamoephic and Fossilifeeous E,oces of tJie county of 

 Galway. By Professor E. HaekNess, F.E.S., E.G.S., Queen's 

 College, Cork. 



The portion of the county of Galway which lies between Killery Har- 

 bour on the north and Galway Bay on the south, includes Con- 

 nemara and Joyce's country, one of the wildest and most moun- 

 tainous districts of Ireland. 



A section of the geology of this district is given in Sir Eichard 

 Griffith's Geological Map of Ireland ; and the rocks of the country 

 have been generally alluded to by Sir Eoderick I. Murchison in the 

 last edition of ' Siluria.' 



The rugged Connemara district is for the most part made up 

 of metamorphic rocks, among which patches of granite occur; 

 and this latter rock is found occupying a considerable area on the 

 south of the metamorphic series, and extending to the northern 

 boundary of Galway Bay. It also constitutes the rocky and moory 

 country known as Moycullen, which lies on the west side of Lough 

 Corrib. 



The metamorphic rocks, as they are seen on the northern margin 

 of the granitic area, consist of gneissose strata, which strike east 

 and west, and which, although much contorted, have a prevailing 

 southerly dip, or incline towards the granitic area. On their northern- 

 side rocks occurs a band of limestone, which can be traced west- 

 wards from a few miles west of Oughterard, on the shores of Lough 

 Corrib, for a considerable distance, as quarries of it are seen near the 

 road leading from Oughterard to Clifden. One of these appears near 

 where the Maame Eoad leaves the Clifden Eoad, at a spot called 

 Butler's Lodge ; and here the limestone is light grey in colour and 

 semicrystaUine in structure. From Butler's Lodge it passes west-
