to point to its existence, at least in some cases. I think I am justified 

 in stating, that there is nothing more than an accidental connexion 

 between these tubuli and Oldhamia ; indeed, it appears nearly certain 

 that some, at least, of the animals, whether molluscan or annelidan, by 

 which these tubuli were made, must have lived not merely posterior to 

 the death of the Oldhamia, whose remains make up these layers, but 

 even after the deposition of a layer of mud on these remains. And I 

 cannot conclude without expressing my firm conviction that a careful 

 research, by other and more practised hands, cannot fail to bring to light 

 even more interesting remains than these here described ; for, as may 

 be gathered from the result of this hurried examination, every kind of 

 rock here furnishes us with some trace or other of animal life.

Dr. Kinahan exhibited numerous specimens in illustration of his 

 paper, which gave rise to an interesting discussion, in which many of 

 the members of the Society present joined. 



WEDNESDAY EVENING, DECEMBER 10, 1856. 



J. B. Jukes, Esq., F.B.S., in the Chair. 



The Chairman announced that since their last meeting they had to 

 lament the death of their late Assistant Secretary, Mr. Hitchcock, an 

 event which no one regretted more than himself. 



Mr. Hartstonge Robinson, and J. Maguire, C. E., being proposed and 

 seconded, were elected members of the Society. 



Mr. W. L. "Willson then read his paper : — 



ON THE GEOLOGY OF THE NEIGHBOURHOOD OF KENMARE. 



The valley of Kenmare is about one mile broad at the town, from 

 whence it extends eastwards, gradually becoming narrower for about 

 nine miles, to the village of Kilgarvan. The rock forming the bottom 

 of the valley is the lower carboniferous limestone, which consists of 

 beds of a pale gray crystalline limestone, much jointed and cleaved, 

 the latter giving a thinly laminated and platy structure to the rock. The 

 lowest beds are of a darker gray, and often deep blue colour, and are 

 seen to rest upon blue and black shales and gray grits, with purple slates 

 and sandstones, both upon the north and south of the valley. The 

 general strike of the limestone and other beds in the Kenmare Valley is 

 about 25° north of east ; this strike is very constant for miles over this 

 district.
