4 ' PEOCEEKINGS OP THE GEOLOGICAL SOCIETY. [iS'oV. 20, 



room, might, on a hasty view, be set down as large glacial striae ; a 

 nearer inspection, however, soon dispels this opinion. 



1. The " grooves " (I use the term for convenience) are notr 

 parallel to the bottom of the valley down which the glacier was 

 supposed to slide, nor do they on the two pieces of rock run in the 

 same direction (fig. 1). 



Fig. 1. 



2. The " grooves " may be traced into, and under, a portion of 

 the overlying rock ; and it becomes obvious that they were exposed, 

 not by the action of ice grinding down the overlying rock, but by 

 the tool of the workman 

 the new road cut as a bench along the steep hillside. 



3. The cross section of the beds, of which I give an enlarged 

 sketch (fig. 2), shows that the '^ grooves " are formed by the minor 



removing the rock above in order to form 



folds of the strata ; and the lamination of the interior of the rock is 

 bent so as to correspond with the " grooves " on the surface. 



The evidence, therefore, appears to be conclusive — that the 

 " grooves " have been formed by the minor contortions of the strata, 

 and not by glacial action. 



3. On DiSTTJKBANCE of the Level of the Land near Yoxjghal, on the 

 South Coast of Ireland. By A. B. Wynne, Esq., F.G.S., of the 

 Geological Survey of India. 



[Abridged.] 



The region which has undergone recent disturbance in the neigh- 

 bourhood of Youghal is a part of that referred to in Prof. Jukes's 

 able paper read before the Geological Society " Upon the Mode of 

 Formation of some of the Eiver-VaUeys in the South of Ireland " 

 (see Quart. Journ. Geol. Soc. vol. xviii. p. 378, 1862) with a map,
