Fig. 



\. a, a strong conglomerate at Sybil Head, about 60 feet thick; the 

 base of the Carboniferous formation dipping N. "W. 60° into the 

 Atlantic, and lying unconformably on the ends of the brown- 

 stone strata from a to b. 



g, m, n, h, i, supposed the original surface of the land. 



m, n, o, p, a fossiliferous band of rock. 



h, h, a supposed line of fault or slip. 



c, Jc, a greenstone protrusion at Clogher Head. 



b, h, the white part of a fossiliferous band at Perriter's Cove, sup- 

 posed to have slipped down from the position m, n, on the line 

 h, h, and to be the equivalent of e, p, o, d: a similar fossiliferous 

 band at Doonquin Old Church ; each band a part of the original 

 m, p, o, n. See pp. 15, 16.

 n, o should be shown as grit and slate, the same as between d 

 and e.
