examine them so tlioronghly, and who never had such a rich collec- 

 tion of these animals, were inclined to consider the Flora only, and 

 explained their relations in a directly opposite manner. 



But in medio virtus must also be here the guiding motto, and all 

 circumstances must be considered. 



The age of the Gas-coal in the Kladno-Eakonitz basin, which is 

 especially known for many years from the locality Hredl, was already 

 recognized correctly by Messrs. Keuss (in 1858) and Lipoid (in 

 1862), both taking it as of Permian age, for which they had good 

 grounds. 



1 myself visited this basin for three years with Prof. Krejci, and 

 we could only confirm again these previous observations. But 1 found 

 more. I found that the Flora from above the Gas-coal is throughout 

 Carboniferous, and not one single species is of Permian character. 



1 discussed these relations first in my special paper on this basin,^ 

 and they are also to be found in my subsequent general papers.^ 



Here 1 was the first who pointed out the analogy of the lower 

 Coal-seam with the Coal-strata of Radnitz,^ and described first, more 

 in detail, the localities of the Gas-coal with Permian animal-remains, 

 and a Carboniferous Flora, in the shales above. 



Herr Stur, of Vienna, expressed about this Gas-coal, in one and 

 the same year, two rather different opinions. In his misleading 

 paper on the Bohemian Coal-fields,* on account of the animals, he 

 treats the Gas-coal (Schwarte) without hesitation as truly Permian 

 (or as he prefers calling it, D3'as*) ; but he established a superfluous 

 name for this Gas-coal, calling it " Kounowa Series," while, if a new 

 name be made at all, it should be called Hredler Series, being much 

 longer and much better known from the locality of Hredl. 



In a note, in the Vei'handl. d. k. k. geol. Eeichsanstalt, 1874, 

 Herr Dionys Stur reports on plants from the district of the Gas-coal, 

 and says distinctly that till that time no plants from this district 

 were recorded, although my special paper on the Kladno-Eakonitz 

 basin was already published, and Herr Stur was acquainted with it. 

 Here I enumerated the first plants from above the Gas-coal. Herr 

 Stur was obliged to recognize that those plants were only of Carbon- 

 iferous character. To be able to explain it, Herr Stur at once re- 

 moved the position of the Gas-coal to the very beginning of the 

 Permian, in which he might perhaps not be wrong, although at first, 

 judging from the Fauna only, he thought it higher. We see, how- 

 ever, that the Permian character of this Gas-coal is so apparent that 

 Herr Stur could not transform it, although he would certainly have 

 liked to do so. 



Prof. Krejci, in his excellent short paper," pronounced the last

 without mentioning it, although aware of its existence.
