THE GEOLOGIST. 



" In the strata of the coal series these impressions are generally more 

 or less parallel with the time of stratification, but occasionally they are 

 found vertical." 



" In the Saarbrucken Gymnasial Programme for 1835, M. Golden- 

 burg enumerates one hundred and two species of plants." 



M. Steininger states that he has not been able to examine 

 the accuracy of this estimate, but he enumerates sixty-nine 

 species which are in the Museum of the Society at Trier, 

 which we insert, for the information of such of our readers 

 as are interested in fossil botany.

The third and concluding portion of the work is devoted 

 to a description of the plutonic rocks of the district, not 

 without interest, but too lengthy for us to enter minutely 

 into its details. We will briefly state that M. Steininger con- 

 cludes, " that the carboniferous formation existed prior to 

 the intrusion of the red porphyry and felspathic porphyry,^' 

 (which are the rocks in question) and that an upheaving of 

 those strata took place consequently."
