of the Mendips and elsewhere," ehowed that these fissures must have 

 remained open from a very early period, as they were found to con- 

 tain Liassic and Carboniferous fossils, together with teeth of fishes. 

 Mr, Moore had also discovered land and fresh- water shells, seeds of 

 Flemingites, and large numbers of Foraminifera and Entomostraca. 

 He considered that these discoveries must lead to an entirely new 

 theory to explain mineral veins, as neither segregation nor thermal 

 action could be reconciled with the presence of organic life in these 

 fissures. 



Mr. H. B. Brady noticed the Foraminifera discovered by Mr. 

 Charles Moore, and especially referred to Involutina. The three 

 genera mentioned by him were all still existing. 



Mr. C. W. Peach recorded the discovery of Ortlioeeratites, 

 Corals, &c., in the rocks between Nare Head and Porthalla Cove. 

 This is the nearest point to the Land's End where Devonian fossils 

 have yet been met with. 



Mr. H. Bauerman, in reporting on Ice as an agent to pro- 

 duce Geological change, gave instances of the grooving power of 

 ice as well as its ability to transport blocks and to form moraines. 

 He thought that it would be necessary to obtain international 

 scientific co-operation before accurate data could be brought 

 together. 



Mr. E. Brown adduced evidence to show that the west coast of 

 Greenland was subsiding, and that points along the eastern coast 

 had been elevated. 



Mr. George Maw recorded the occurrence of insect-remains and 

 fresh-water shells from the Lower Bagshot Leaf-bed of Studland 

 Bay, Dorsetshire, not heretofore observed. 



Dr. Henry Hicks gave an account of the discovery of Fossil 

 Plants (?) in the Cambrian Eocks, near St. David's. In these 

 Upper Longmynd rocks Dr. Hicks has met with many new species 

 of Trilobites 1500 feet below the horizon at which organic remains 

 had hitherto been found. He had also detected plant-remains, but 

 they were doubtfully referred to plants, and were considered to be 

 the tracks of Annelids and Trilobites by Professor Phillips and Mr. 

 Etheridge. The importance of Dr. Hicks's discoveries is neverthe- 

 less very great, and we cannot but deeply regret that he has, by 

 death, been deprived of the valuable co-operation of Mr. J. W. 

 Salter (our highest authority on paloeozoic fossils) in carrying on 

 these researches. 



Dr. Mann gave a description of the Gold country of Natal, and 

 the localities where the precious metal had been met with. 



Mr. W. Stephen Mitchell presented the " Eeport of the Committee
