Analysis of Spar in TalJeis. 



Spar in tablets* is oenerallv found in a mixture of brown 

 crysialiizcd granite and blue calcareous spar, of which it

 Stut/, calls it spar in tablets, because it exhibits in its frac-

 M. Stutz, at Dognaska in the canal of Temcswar, and ac- 

 cording to M. Estner, at Oravuza.

The lime in it is not carbonated, for nitric acid poured

 a>^paragus green colour, crystallized in flattened triangular 

 pyramids : it is of mean hardness and gravity, rough to the 

 touch, &,c. A hundred parts of miemite contain 



• The analysis of spar in tablets is found in Klaproth's work next to 

 that of pl.arrraciiiitt and scor/.a sand, as well as that of miemitc.
