98 DR BOtJE' ON THE GEOGNOSY OF GERMANY. 
Saltzkotten, near Paderborn, to Bielefeld and Hilter ; and 
extends behind Paderborn as far as the neighbourhood of 
Herrenhausen and Kreutzkrieg. There it forms, in the 
undermost part, a true greyish limestone, with nodules of 
black flint ; and, in the uppermost part, it is a whitish 
marly limestone, with many echinites, belemnites, myti- 
lites, &c. It just re-appears near Hanover and Luneburg, 
but forms, farther east, pretty extensive hillocks and plains 
along the Hartz, from Unter-Elbe as far as Quedlinburg. 
At this last place, the coarse chalk passes insensibly into 
the true chalk with flint, having belemnites, echinites, tere- 
bratulites, &c. in abundance. 
The chalk extends also into Moravia, and forms, parti- 
cularly near Tribau and Lissitz, a pretty extensive range 
of hills, in which petrifactions are in some places abundant, 
in others very scarce. Near Blansko, the last point which 
this deposit has reached, it contains shells resembling am- 
monites ? or argonautes ? and small bivalves ; and here it 
covers a coarse sandstone, under which is situated, first, 
a siliceous rock, containing flint-nodules, echinites, and 
small bivalves, and, undermost, a white sand (Quadersand- 
stein), with rich deposits of cellular and pisiform brown 
ironstone (hydrate of iron). This last deposit is only found 
in three places, — at Olomuczan, and Knditz, near Blansko, 
where it lies in hollows of transition-limestone, and at Sal- 
hanka, upon gneiss. 
To complete the enumeration of localities where chalk 
is found in Germany, I have still to mention the Isles of 
Zealand, Moen, WoHin, and Rugen, and the Lake of 
Ucker. In many other points of the eastern part of Prus- 
sia, it seems to be indicated, or to be but slightly covered, 
by the following formations, and in Poland it is very wide- 
ly distributed.
