examine thera so thoroughlv, and who never had such a rieh Collec- 
tion of these aniraals, were inclined to consider the Flora only, and 
explained their relations in a directly opposite manner. 
But in medio virius must also be here the guiding motto, and all 
circumstances must be considered. 
The age of the Gas-coal in the Kladno-Rakonitz basin, which is 
espeeially known for many years from the locality Hredl, was already 
recognized correctly by Alessrs. Reuss (in 1858) and Lipoid (in 
1862), both taking it as of Permian age, for which they had good 
grounds. 
I 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, 1 
and they are also to be found in my subsequent general papers. 3 
Here I was the first who pointed out the analogy of the lower 
Coal-seam with the Coal-strata of Radnitz, 3 and described first, more 
in detail, the localities of the Gas-coal with Permian auimal-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, 4 on account of the animals, he 
treats the Gas-coal (Schwarte) without hesitation as truly Permian 
(or as he prefers calling it, Dyas 5 ) ; 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. 
ln a note, in the Verhandl. d. k. k. geol. Reichsanstalt, 187-1, 
Herr Dionys Stur reports on plants from the district of the Gas-coal, 
and says distinctly that tili that time no plants from this district 
were recorded, although my special paper on the Kladno-Rakonitz 
basin was already published, and Herr Stur was acquainted with it. 
Here I euumerated 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.
