19S The Rev. W. Conybeare on 



perienced In surveying, to construct such projections as have been 

 described from their detached sketches ; and to such objections it is 

 felt that the present example lies particularly open : it is indeed 

 offered merely as an approximation to a correct representation. 

 Such as it is, however, it is presented to the Society, in the belief 

 that the en-ors are not of a nature to interfere with fidelity 

 in laying down the great geological features which distinguish this 

 interesting coast, and that these features are in themselves so 

 important as to render s.ay delineation which might in this respect 

 (however imperfect in others) pretend to some degree of accuracy, 

 desirable. 



In describing these sections the very ample information collected 

 by Dr. Berger concerning this district, will render It unnecessary to 

 exceed the limits of a rapid survey -, this I shall commence at the 

 south-east extremity of the line represented, proceeding towards 

 the north-west. 



In this direction the lias formation is seen at the extremity of 

 the section occupying the lower regions of the promontory over 

 which the Deer park of Glenarm extends, near its southern point ; 

 the ground here ascends with a rapid slope, above which cliffs of 

 chalk covered by basalt rise to a considerable height : advancing 

 towards the north the lias dips beneath the level of the sea, and 

 the beach is skirted by a chalk cliff. 



On doubling the promontory, Glenarm presents itself situated 

 in a narrow valley bounded on the east by the Deer park hill, and 

 on the west by Bellaire hill, both of which in their sections towards 

 the sea exhibit cliffs of chalk covered by basaltic platforms. The 

 distant hill seen rising above the opening of this valley, is Slieve 

 Mish, it consists entirely of greenstone. Near Glenarm is the 

 remarkable compound dyke mentioned in page 172.
