The discovery of these fossils is interesting, on account of the scarcity of 

 organic remains in the Silurian rocks of this part of Ireland, and their palse- 

 ontological evidence fixes the age of the beds in which they were found as 

 belonging to the Lower Llandovery period. 



Although the rocks containing these fossils are obviously of Silurian age, 

 the author felt called upon to mention incidentally, upon the authority of the 

 discoverer, J. Darby, Esq., that an old Cambrian fossil, Oldhamia radiata, had 

 been found upon the hill, and the specimen itself was laid before the section. 

 A strong probability certainly exists that it might have been found in situ 

 here, but unfortunately, as its locality could not now be pointed out, the fact 



RECENT ENCROACHMENTS OF THE SEA ON THE SHORES OF 



TORBAY. 



If, as some masters of our science tell us, and as I venture to believe, the 

 geological changes which have passed over our world during the unmeasured 

 ages of the past, were due to the direct and indirect operation of existing 

 causes, acting, perhaps, with intensities not greatly dissimilar to those they 

 now display, it can scarcely be out of order to call attention, from time to time, 

 to changes taking place nnder our immediate observation, even though they 

 may be slight in themselves, and, regarded as isolated facts, of little worth or 

 importance. 



Bequesting the Section to keep this apologetic preface before them, I will 

 now proceed to narrate a few facts respecting the recent encroachments of the 

 sea on the shores of Torbay,
