ITALY. LETTER XXVI. JSp 



Behind Infpruck occurred low hills of ftratifie 

 friable and compacter limeftone j its colour light- 

 grey or blackifti-grey, with calcareous veins. 

 Gently they afcended into higher hills of large 

 grey calcareous beds, which between Nefereit and 

 Lermos formed calcareous Alps, of a remarkable 

 elevation. Clofe to Lermos is a fteep calcareous 

 Alp, called the Sonnenfpitz, or the \Yetterfiein, in 

 which a lead and Giver-mine, called Silberlcuthen, 

 is working. 



Beyond Fuefien towards Augfbourg the country 

 . is plain and flat. 



Near Augfbourg I faw blunted and detached 

 pieces of black porphyry, with white oblong fpots. 

 The fame to be found near Munich, and the con- 

 vent Varenbach, on the Inn. In Bavaria are very 

 commonly found large detached pieces of grafs- 

 green quartz, or rather emerald-matrix (Cronfted's 

 Mineral. 73.) with red tranfparent garnets, 

 which at Munich they miftake for Granite, and 

 work into fine muff-boxes and other trinkets. 



Some hills about Regenfburgh are calcareous ; 

 towards Bohemia they confift of Gncifs and Gra- 

 nite. I faw here, near fome mills on the Danube, 

 quantities of fquare-cut grey Granite, fpotted with 

 large parallelepiped of milk-coloured feld-fpath. 

 You are acquainted already with Dr. Shejjer's
