ORDER XIII. PRISMATIC SULPHUR. 55 



&c. It is deposited from several springs, and in large 

 quantities from volcanoes. Sometimes it occurs in beds 

 of bituminous Mineral-coal. 



4. Prismatic Sulphur is found in splendid crystals, and 

 pure massive varieties, also in globular concretions, which, 

 however, are seldom without earthy or bituminous admix- 

 tures, in Sicily, and several provinces of Italy. It occurs 

 in imbedded spheroidal masses of a brown colour, which is 

 owing to bitumen, at Radoboy near Crapina in Croatia. 

 Near Cracovia in Poland it is likewise met with in more or 

 less pure massive varieties and small crystals. The finest 

 crystals, besides Sicily, are known from Conil near Cadiz 

 in Spain. Small crystals have been observed investing 

 the brown coal from Artern in Thuringia. In veins it oc- 

 curs in Swabia, in Spain, and in Transylvania. The earthy 

 Sulphur is found in Poland, in Moravia, and other coun- 

 tries, the volcanic Sulphur in Iceland, near Vesuvius, 

 in the Solfatara, in fine crystals in Teneriffe, in great 

 profusion near the volcanoes of Java, and in the vicinity 

 of most other active volcanoes. Prismatic Sulphur occurs 

 besides in Savoy, in Piedmont, in Switzerland, at Lauen- 

 stein in Hanover, in South America, and many other 

 countries. 



5. Prismatic Sulphur requires to be purified, either by 

 melting or by sublimation, for rendering it fit to be an ob- 

 ject of commerce. It is used in the manufacture of gun- 

 powder, of cinnabar, of several pharmaceutical preparations, 

 of sulphuric acid, and various other articles.
