productive coal-fields of Waldenburg, succeeded 
by a copious development of red rocks 
(Roth-liegende), grouped many years 
ago by me with Permian deposits, and 
which have already been described (pp. 
314 &c.) *. 
Again, in Moravia f the order of the 
older Palaeozoic deposits is very analo- 
gous to that which prevails in Silesia. 
There I have observed crystalline schists 
and limestone, representing Silurian for- 
mations, followed by masses of lime- 
stone which at Rittberg and other 
places around Olmiitz are charged with 
Devonian fossils. Some of the strata, 
in tracts that I have not seen, are re- 
ferred to the Carboniferous era. The 
crystalline rocks which range thence, 
or front the Sudeten Mountains into 
the Bohmerwald-Gebirge, and have 
been generally described by Partsch %, 
Heinrichs, and others, consist of gneiss, 
mica-schist, chlorite-schist, and horn- 
blendic slates, with saccharoid lime- 
stones, the whole being penetrated by 
granite, syenite, greenstone, serpentine, 
&c. Although portions of these vast 
masses may probably represent the Si- 
lurian series, the greater part of the 
schistose rocks (including limestones) 
in which fossils have been detected are 
clearly of Devonian age, as has been 
elsewhere shown §. 
Silurian and subjacent Rocks of Bo- 
hemia and Bavaria. — If the traveller has 
worked his way round from Britain 
through Scandinavia. and Russia into 
North-eastern Germany, and has there 
lost the clue whereby he could have 
j identified the lower crystalline schists 
| and limestones of Silesia and Moravia 
m with their representatives in the west- 
ern, northern, and eastern regions of 
Europe, he will indeed be rejoiced
