V. NEWER GRAUWACKE OF THE HARZ, SAXONY, AND 



SILESIA. 



(The equivalent of the lower beds of the English Coal Formation.) 



The species marked f occur also in the Carboniferous Limestone, those marked ff 

 in the Coal-measures, and those marked * in the Posidonomya-schist.

Results. — Though 1 dare predict, says the Professor, that within 

 a few years after the publication of my work a great number of addi- 

 tional species will be discovered in the Transition series (fifty have 

 been observed by myself in Silesia alone, a very limited area in com- 

 parison with the extent of this formation), yet I will venture to draw 

 some conclusions from the phsenomena of which we are already 

 cognizant. 



1 . Land-plants are not found in the oldest or Silurian strata^ as the 

 very elaborate researches of the American geologists prove. It is to 

 be hoped that equally careful investigations will before long settle this 

 question for Europe also. Marine plants, and especially Fucoids, 

 constitute the first form of vegetation on our planet. Yet we cannot 

 affirm, although some of these plants, for example, Harlania Hallii, 

 appear to have possessed a very peculiar organization (with respect 

 to which further researches can alone enlighten us), that this earliest 

 vegetation was really so different from the existing marine flora, as
