1823.] Rothetodtliegende and Weissliegende. 323 



call the true rothetodtliegende the new conglomerate, and then 

 to build on this misapplication of the term, is a sure method to 

 render a subject, otherwise simple and clear, involved and con- 

 fused ; and thus calculated to mislead both the writer and reader, 

 confirming the remark of Bacon, that " while men believe their 

 reason governs their words; it often happens, that words have 

 power enough to react upon reason." 



I have maintained that the rothetodtliegende formation is the 

 equivalent of the carboniferous series, extending from the old red 

 sandstone to the coal formation inclusive, or vice versa. Now to 

 prove that Freiesleben's own view of the matter is identical with 

 that which I have given, I think it will be sufficient, in addition 

 to the facts detailed in my former papers, to transcribe in this 

 place the Synoptical Table of that author, prefixed to his fourth 

 volume, which exhibits the method according to which he con- 

 siders and treats this subject ; and then to offer a few remarks 

 intermingled with such illustrative extracts from the body of the 

 work, as bear more immediately on the question.
