Elie de Beaumont has in this manner distinguished about fifteen systems of elevation, according to their age and direction, of which the most remarkable are the twelve following. 1. System of Westmoreland and Hundsruek.--Direction of elevation, N. E. E. and s. w. w. No newer strata than the Silurian, and probably a part of Devonian, uplifted. This includes the Eifel, the Taunus, the Isle of Man, and South Shetland. 2. System of part of the Vosges.--Direction, E. 15 s., w. 15 N. Mountain limestone, but not the coalbearing strata, uplifted. To this belong the hills of Bocage, in Calvados. 3. System of the North of England.--Direction, s.--N. The coal-bearing strata are the most recent affected in this elevation. 4. System of the Netherlands and of South Wales.--Direction, N. E.--s. w. The whole of the coal formation affected. 5. System of the Rhine.--Direction, s.--N. or s. s. w.--N. N. E. Strata to the zechstein (magnesian limestone) uplifted. The Vosges, Schwarswald. 6. System of Bohemian and Thuringian Forests.--Direction, s. E.--N. w. The keuper is the newest formation disturbed. La Vendee, Bretagne. 7. System of the Erzgebirges.--Direction, s. w.--N. E. The oolite or Jura, but not the quadersandstein, affected. Cote d'Or, Mount Pilas and the Jura in part. 8.

The younger or upper chalk, but not the tertiary strata, affected. This system being parallel to No. 6, it is often difficult to separate one from the other. Hartz, Teutoburger Forest, &c. 10. System of Corsica and Sardinia.--Direction, s.--N. The lower tertiaries, but not the up...
