EUROPE. 71 



with beds in the other French basins, the results bein» presented in 

 tabular form. It is held that there has been no proved passage between 

 the Gault and the gluu-onitio Chalk (CenomaiiiaM), but that in the 

 supposed instances the G.iult fossils are derived. Lastly, the move- 

 ments of the ground and the physical relations of the beds are discussed.

Helmhacker, Dr. R. Ueber das Alter der Pilsner Cannelkohle. [Ago 



of the Cannel Coal of Pilsen.] Jahrh. k.-lc. Bergakad. Bd. xxiii. 



pp. 243-277. 



Discusses the views recently adopted as to the age of the cannel 



coal occurring in the uppermost part of the Pilsen coal-field, which 



had been assigned to the Permian as a new subformation, Kohlen- 



E,)thliegende or lowest Permian. Analyzes the evidence of the 



plants and animals found in association with this coal, and concludes 



that, with some portion of the overlying strata, it forms part of the 



Coal Measures. H. B.
