Analysis of some Asphaltic Slates and Limestones from 

 Seefeld in the Tyrol. By M. Kraynag, Manager of the 

 Saltworks of Halle, 



[Proceedings Imp. Geol. Instit, Vienna, April 8, 1856.] 



These limestones contain from 7*28 to 7*71 per cent, of resinous 

 substances soluble in alcohol, aether, and turpentine. A bituminous 

 slate from Seefeld contained 13'01 per cent, of bitumen and 80*13 

 per cent, of carbonate of lime. The distillation of a resinous red 

 asphalt-stone gave 14*3 per cent, of petroleum : a black variety of 

 the same stone gave 20 per cent. The naphtha extracted from the 

 Seefeld asphalt has a specific weight of 0'847 ; it is composed of 

 Carbon, 80*73 ; Hydrogen, 1107 ; and Oxygen, 8*19 per cent.

On the North-Eastern Alps. By M. Stur. 



[Proceedings Imp. Geol. Instit. Vienna, April 30, 1856.] 



M. Stur, having prepared a map of the Neogene, Diluvial, and 

 Alluvial deposits in the N.E. Alpine territory, on which the Leitha- 

 limestone, the freshwater deposits, the lignites, and the true brown- 

 coal were distinguished, as well as the " Diluvial" terraces, levels, 

 erratic blocks, and moraines, by peculiar tints, explained the in- 

 dications of the successive disturbances of the Tertiary and Post- 

 tertiary strata, the lines of which were also marked on the map. M. 

 Stur*s researches had led him to the following results. He con- 

 sidered that — 1. An upheaval of the Alps, attended by great dis- 

 turbance of the strata, took place after the deposition of the Eocene 

 beds, and gave origin to the transverse Alpine valleys. — 2. A sub- 

 sidence took place after the plastic clay had been deposited ; and 

 another, to a greater extent, after the deposition of the sands. — 3. 

 Subsequently to the deposition of the gravels in the Alps and on the 

 plains, the Alps were again upheaved, though not so forcibly as at 

 the former period of upheaval. 



The deposits of plastic clay, sands, gravel, and " diluvium" within 

 and without the Alps are ascribed by M. Stur to the results of these 

 changes in the level of the Alps and of the Tertiary sea surrounding 

 them. It is impossible to identify the two subsequent upheavals of 

 the Alps. The uprise of the strata of the Swiss molasse might be
