COP.RYS WITH OB WITHOUT LAKE-BASINS. 



EMBOSOMED in a corry or coom, a small lake is often 

 found. Sometimes in a true rock-basin, but more 

 often in a basin partly rock and partly drift; or even, 

 as previously mentioned (as in the case of the basin 

 of Lough Bellawaum), it may be solely drift. To 

 this subject special attention has been drawn by the 

 Rev. M. H. Close, M.R.I.A., &c., in a paper, "On 

 some Corrys and their Rock-basins in Kerry." 1 



From this memoir it would appear that the author 

 considers the formation of corrys to be largely due 

 to ice action. The following is an epitome of his 

 reasons for coming to this conclusion : 



a. Corrys cannot have been formed by the atmos- 

 phere, for this agent is now engaged in trying to soften 

 them away ; nor by the sea, for the following reasons : 

 The sea does not seem to be now producing such 

 features on the S.W. coast of Ireland. The floors of 

 contiguous corrys are often of very different ele- 

 vations; while there are no apparent terraces on the 

 open mountain-sides corresponding with the corry
