284 Scientific Meeting in Germany. 



Sir Roderick Murchison laid before tile meeting the most recent 

 publications of the Geological Survey, consisting of maps, sections, 

 &c, as illustrative of the Silurian or older palaeozoic rocks, the 

 coal measures, and the secondary and tertiary deposits ; and he 

 also referred to the records of the School of Mines and the De- 

 cades of Organic Remains, which exhibited the labours of various 

 distinguished English geologists. M. E. de Verneuil observed 

 that, whilst Sir R. Murchison had borne such willing testimony 

 to the distinguished merits of his colleagues, he had entirely over- 

 looked his own services ; and pointed out that, in regard especr 

 ally to the School of Mines, Sir Roderick had had the greatest 

 share in its extension and results, both through the great works 

 which he had himself accomplished, and through what others had 

 accomplished under his guidance and superintendence. 



Herr Von Carnall exhibited a copy of the new edition of his 

 geognostical map of Upper Silesia, and explained in what respects 

 it differed from the first edition. He took occasion to remark that 

 of the ironstone rocks of Upper Silesia it was only a portion that 

 could be regarded as middle-Jurassic ; the portions of this forma- 

 tian lying to the north and west of Oppel, and the great Rybnik 

 and Rattibor portions, must be regarded as tertiary-miocene. Un- 

 der these strata lay the Upper Silesian gypsum and marl rocks 

 (tegel) with traces of salt, which are now in the course of being 

 investigated. 



Professor Von Zepharovich of Cracow, spoke of the progress 

 that had recently been made in the knowledge of Austrian mi- 

 nerals, and pointed out the necessity of collecting and arranging 

 the results of inquiries made during long periods of time in order 

 to obtain a synoptical view of what had really been accomplished. 

 He next exhibited a few printed sheets of a large work of this des- 

 cription applicable to the Austrian empire, and mentioned that 

 the work itself would probably be published in the course of next 

 year. He then handed the President a piece of fossil iron from 

 Chotzen in Bohemia. Thereupon Dr. 0. Volger, with reference 

 to the aqueous origin of iron, mentioned the fact that Herr Von 

 Baer had found in a fossil tree imbedded in the turf of a floating 

 island on the coast of Sweden, which only occasionally emerged 

 from the water, that the mass by which the cells had been replaced 

 consisted of native iron. 



The proceedings of the day were concluded by a few short but 

 exceedingly interesting remarks from Professor Blum (Heidelberg),
