present outlines of the country are not to be traced back to the 

 operation of underground forces, but mainly to the action of subaerial 

 agents. In proof of this statement the speaker indicated the lines of 

 the great faults ascertained in the course of the prosecution of the 

 Survey, and showed that, instead of coinciding with lines of fault, 

 the valleys in reality run across the faults in all directions, and 

 without any reference to their existence. He concluded by con- 

 gratulating the Society upon the growing recognition of the pre- 

 eminent genius of Hutton, whose views were first promulgated 

 within the walls of the Society. Hutton he regarded as the father 

 of modern physical geology, and we are now only coming abreast 

 of him, so far was that great man in advance of his time. All the 

 examination and scrutiny which the detailed work of the Geological 

 Survey involves has hitherto only served to confirm and extend the 

 views which Hutton was the first to enunciate.

 " Notes on Graptolites and allied Fossils occurring in Ireland." By 

 W. H. Baily, Esq., F.G.S. [First Paper.] 



After remarking that the Gi'aptolites are now generally re- 

 garded as belonging to the class Hydrozoa, the author detailed the 

 various localities in the south of Ireland in which they had been 

 found, and indicated the species occurring in each place. The 

 localities are situated in the counties of Waterford, Wexford, Clare, 

 and Tipperary ; and the species are as follows : — 



Cladograpsus gracilis, Hall. 

 Biplograpsus pristis, His. 

 ,, mucronatus. 



,, teretiusculiis. 



,, dentatus, Brongn. 



CUmacograpsus bicornis, Hall. 

 Dicratiograpsus ramosus. Hall. 

 Gyrtograpsus gracilis, Hall. 

 ,, hamatus, Baily. 



The most widely distributed of all is Diplograpsus pristis, to 

 which the author thinks D. mucronatus and dentatus probably belong. 

 The fossils described by the author as Theca cometoides may pro- 

 bably be the gonothecee of D. pristis, as had been suggested by 

 Mr. Carruthers. 



Discussion. — Mr. Carruthers remarked that while almost all observers have re- 

 ferred these creatures to the Hydrozoa, there was an impression abroad, founded on a 

 misconception of a remark of Prof. Huxley's, that he classed them as Polyzoa. He 

 had, however, Prof. Huxley's authority for saying that he did not so regard them. 



2. "Notice of Plant-remains from beds interstratified with the 

 Basalt in the county of Antrim." By W. H. Baily, Esq., F.G.S. 



The deposit referred to by the author was discovered by the late 

 Mr. G. V. Du Noyer in cuttings of the Northern Railway of Ireland 

 near Antrim ; it consists of a layer from 4 to 8 inches in thickness, 

 separated by a conglomerate bed of 10 or 12 feet from the under- 

 lying basalt, and by earthy beds of about equal thickness from the 

 superficial basaltic layer. The remains are embedded in a Eed 

 Clay, and associated with hsematitic iron ore.
