Thus, supposing the affinities of the fossils from the Oural and 

 Prince Edward Island to be correctly determined, the Eeptilia dis- 

 tinguished by Mammalian characters are shown to have had a very 

 M^ide range. Further, the author thinks that the Theriodont Keptiies 

 of the Bristol Dolomitic Conglomerate may also prove to constitute 

 a family in the Theriodont order. 



The Earl of Enniskillen stated that when Prof. Agassiz first came 

 to England, he employed Mr. Dinkel to draw the fossil fishes, and- 

 obtained the fine collection of drawings which was subsequently 

 presented to the Geological Society by the late Earl of Ellesmere. 

 By a special arrangement. Lord Enniskillen and Sir Philip Egerton 

 paid for those drawings which were made from each other's col- 

 lections, the drawings remaining their property. In this way Lord 

 Enniskillen is the possessor of those drawings which were made for 

 Professor Agassiz from Sir Philip Egerton's collection, and it was 

 his intention to leave them by his will to the Geological Society in 

 order that they might be added to the set already in the Society's 

 possession. Owing to the almost total failure of his eyesight, the 

 figures in Lord Enniskillen's possession are now quite useless to 

 him, and he proposed to present them at once to the Society. 



The President offered the thanks of the Society to Lord Ennis- 

 killen for his intended present, and at the same time gave expression 

 to its regret at the cause of his Lordship's determination.

At the meeting of this Society, May 4, 1876, Dr. Th. Nordstrom 

 exhibited and described a theodolite, constructed by the late Mr. 

 Barthelson, for the purpose of mapping mines. 



Dr. E. Svedmark gave an account of some microscopical researches 

 on Uralite-porphyry from Yaksala near Upsala in Sweden. 



Mr. E. Erdmann called attention to the power of the waves 

 in denuding, grooving out and grinding rocks along the sea-shore, 

 and exhibited a model, constructed by himself, showing the result of 

 this power on the almost perpendicular layers of sandstone at the 

 coast of the Firth of Forth, near Edinburgh, a place visited by him 

 last year. He then exhibited some samples of sand, etc., from a 

 deep boring at Gothenburg, in Sweden, where, at a deptli of from 

 114 to 116 feet under the surface, and about 100 feet below the 

 level of the sea, a shell-bed, or a bed of sand with many remains 

 of shells, had been discovered. Mytilus, Balanus, Yoldia and Fora- 

 minifera were found. This shell-bed at so great a depth below the 

 sea-level may perhaps indicate that the land here once, during or 

 later than the Glacial Period, was higher than it is at present. He 

 also exhibited some specimens of jasper, which Dr. A. G. Nathorst 

 had found in Skane (Scania) as small layers and lenticular masses in 

 a sandstone, probably of Triassic age. 



In reference to the account of Mr. Erdmann of the denuding 

 power of the waves, Prof. 0. Toreli and Dr. Nordstrom drew
