S32 - M. Roue' o«l 



The sandstone of Hildesheim sometimes contains terebra- 

 tulae (t. acuta. Schl:), and between StoflFenheim and Teilho- 

 sen in Bavaria, I have seen, in the coarse ferruginous sand- 

 stone, immediately beneath the lias, a great abundaace of 

 the gryphites arcuata and belemnites. 



Echinitcs and pinnites (p. diluvianus) are mentioned as 

 rarities from Pirna, as also the remains of encrinites ; yet the 

 latter are sometimes very abundant in some of the upper 

 beds, and are mixed with bivalves (mytilus ?) as in the 

 StafTelsberg, near StafFelstein, and at Blumenroth in Coburg. 



Certain singular prominencies of this sandstone might lead 

 us to suspect the existence of crustaccae. 



This formation is not only distinguished by the nature of 

 its rocks and fossils, but it very often constitutes mountains 

 of a very peculiar form, in consequence of its irregular de- 

 composition or cementation. Thus when this formation is 

 not covered by the oolite formation, as iu Bavaria, or else 

 by chalk, it presents a suite of indented crests, with very 

 singular rpuuded sections; such is for example the Devil's 

 Wall or the Taufelmauer, between Blankenburg and Hal- 

 berstadt, and the indented heights along (he Elbe, between 

 Pirua and Petchen. 



When this formation has been much destroyed and a few 

 patches of it only remain, we then observe it to form simple 

 walls, as at Goslar, or singularly shaped blocks, as at Hack- 

 stein, near Hirchberg, in Bohemia, &c. 



Its valleys are deep, with very steep and nearly vertical 

 slopes, at least when the deposite has been considerable, 

 as between Tanneberg and Bohmish, Kamnitz, and near 

 Oschitz in Bohen^ia, or else the valleys are very much 

 hollowed out, the bottoms being occupied by more ancient 

 formations, whose heights are alone covered by sandstone, 

 as in many localities in the N.E. of Bohemia, and northern 

 Bavaria. After having described this formation as exactly 

 as I am able, I may be permitted to pass in review its known 

 localities. 



This formation had long been described in Bohemia, and 

 it was there known to cover the coal measures and red
