Mr. D. Page next gave a brief and interesting Notice of some new Boreal 

 forms of Moliusca from the Pleistocene deposits of Scotland. 



Rev. W. S. Symonds, " On some Eislies and Tracks from the "Passage-rocks," 

 and from the Lower Old Red Sandstone of Herefordshire." 



Rev. H. Lloyd, " On the Affections of Polarized Light reflected from and 

 transmitted by tliin plates." 



Professor Daubeney, P.R.S., "On certain Yolcanic Rocks in Italy, which 

 appear to have been subjected to Metamorphic Action." 



Dr. M'Gowan, " On certain Phenomena attendant on Yolcanic Eruptions and 

 Earthquakes in China and Japan." 



Messrs. Garner and Molyneux, " On the Coal-fields of Staffordshire." 



C. Moore, E.G.S., "On Brachiopoda, and on the development of the loop in 

 Terebratella." 



Dr. Buist, E.G.S., " On the Geology of Lower Egypt." 



The President read a letter from Dr. Dawson, E.G.S., intimating certain dis- 

 coveries which he had made of a land-sheU and reptiles in the South Jog- 

 gins Coal-field, Nova Scotia, and enclosing two specimens. 



Professor Nicol, E.R.S.E., gave an able and interesting notice on the " Re- 

 lations of the Gneiss, Red Sandstone, and Quartzite in the north-west High- 

 lands," Illustrated by various sections. Professor Nicol had visited the High- 

 lands, and had arrived at a different conclusion as to the succession of certam 

 crystalline and sub-crystalline rocks from that arrived at by Sir R. Murcliison. 

 He contended that the great series of rocks in question were of older date than 

 that assigned to them by Sir R. Murchison, and endeavoured to prove, by a 

 reference to the sections which he exhibited, that the order of superposition 

 which he advocated was the correct one. 



Professor Huxley read a paper on " Newly discovered Reptilian re- 

 mains from the neighbourhood of Elgin." 



Rev. Professor Sedgwick, " OnEaults in Cumberland and Lancashire." The 

 object of the Professor's description of the faults in Cumberland and Lanca- 

 shire was to show that there was really no violation of the order of super- 

 position of the strata. 



Professor Rogers, " Some Observations on the Parallel Roads of Glenroy," 

 in which he described the leading features of the district, and indicated as his 

 opinion that the shelves or grooves on the surface of the hills had been formed 

 by water in motion, and not by water at rest, as had been supposed. 



Professor Harkness, "On Sections along the Southern Elanks of the 

 Grampians." 



Mr. J. WyUie, " On some Old Red Sandstone Eossils." 

 Mr. C. W. Peach, " On New Eossil Eish from Caithness." 

 Mr. W. H. Baily, E.G.S., "On some Tertiary Eossils from India." 

 Adolphe Radiguel, C.E., " On a Eragment of Pottery found in a Superficial 

 Deposit." 



M. Gages, " On the Results Obtained by the Mecanico-chemical Examination 

 of Rocks and Minerals." M. Gages had invented a new mode of examining 

 metamorphic rocks. Instead of reducing them to powder, he simply broke 

 them down and then submitted them to chemical tests. By this means some 

 remarkable results had been obtained. 



Mr, C, G. Thost, " On the Rocks and Minerals on the Property of the Mar- 

 quis of Breadalbane." 



Mr. Brady, " On some Elephant-remains at Ilford." The chief of these was 

 the tusk of an enormous mammoth, identical with the Siberian mammoth. 

 Remains of coniferous and other plants yet existant were found in the same 

 strata. 



Mr. J. Miller, " On the Age of the Reptile sandstone of Morayshire."
