Plate XL. — {Lithographic View of Gosau-thai.) 



In the foreground are the church and principal village of Gosau-thal. The wooded 

 mountain on the right, is the Horn, that on the left is the Ressenberg; the summit 

 of the former being composed of reddish, gritty sandstone, the latter of greenish, 

 micaceous whetstone ; and both are based upon blue marls with a profusion of 

 shells, which are best exposed in deep ravines right and left of the spectator. 



The steep and arid peaks in front consist of Alpine limestone, chiefly considered as 

 the equivalents of the oolitic series, and are called in the neighbourhood the 

 Stein Gebirge, each peak being known by a local name, as the " Donner Kogel," 

 " Henner Kogel," &c.
