duff, and Hillbrook, some of them being on the borders of the 

 counties of "Wexford and Wicklow, are detached exposures of 

 ophyte. They are of various shades of green, generally dark- 

 coloured. 



South-west of the spur of high ground last mentioned, and a 

 little west of Carnew, in the Co. Wicklow, there is a tract of 

 dark-green ophyte, in places spotted with red, like a bloodstone. 

 It is capable of taking a good polish. 



Much further northward, about half way between Anamoe and 

 Togher or Eoundwood, is a large boss of dark-green ophyte. 



EKLOGYTE. 



[Speckled and mottled, green and brown, recorded from Galway, Mayo, and Sligo.] 



GrALWAY. 



To the W. N. "W. of Kylemore Castle, in the townland of 

 • Curry wongaun, there is a vein of greenish-brown speckled eklo- 

 .gyte. A small opening was made by Mitchell Henry, M.P., who 

 had some of the rock cut and polished at his saw-mill. 



A little south of Grarroman or Grlendollagh Lake, in the mass of 

 ophyte previously mentioned, is a pipe vein of spotted bright-green, 

 eklogyte. 



Mayo. 



A little south-west of Ballyhean, on the north slope of Tona- 

 derrew, there is a mottled light-green eklogyte. The rock in this 

 locality is very like the previously-mentioned rocks near Luga- 

 loughaun and in Grlencullin (see Ophytes, page 406), and it is pos- 

 sible that the rocks in these places should be classified with the 

 -eklogytes, and not with the ophytes. 



Sligo. 



The rocks previously described among the ophytes, at Slish- 

 wood, Drumahair, and near Manorhamilton, seem to partake very 

 much of the nature of eklogyte, and possibly ought to be so 

 classed.
