III. NATURAL HISTORY. 
MTNEltALOGY. 
17. Ripel and PristanousJcy's Works. — Ripel, an intelligent 
mineralogist, is preparing a great work on the structure of the 
Alps, to be accompanied with numerous sections and maps. 
High expectations are formed of Pristanowsky’s work on Tus- 
cany, about to appear ; as he, in opposition to all the French,, 
and most of the German geologists, advocates the Neptunian 
view of their formation. The same active observer has lately 
published an interesting tract, in which he shews, that, in the 
newer rocks, along both sides of the Appennine range, there 
are extensive sulphur beds ; that these are more considerable on 
the south than on the north side, and that probably the fuel of 
Italian volcanoes is sulphur. 
18. Geognosy of Brazil. — From the account of Eschwege, it 
appears that this country is composed of rocks of the primitive, 
transition, secondary and alluvial classes. The primitive rocks 
he divides into two classes ; under the first, he includes granite, 
syenite, trap, gneiss, mica- slate and limestone ; under the se- 
cond, clay-slate, quartz-rock and quartzy mica-slate, chlorite- 
slate, talc-slate, potstone, and slaty quartzose micaceous iron-
