Present strata composed of the remains of more ancient rocks, § 1. Proofs from calcareous strata, § 2.—from siliceous, § 3.—from argillaceous, § 4.—from bituminous, § 5, 6. Absence of organized remains from the strata called primitive, not universally true, § 8, 9.—Term Primary substituted for Primitive. Composition from the materials of more ancient rocks, § 10.
2. Consolidation of the Strata.
Consolidation, what, § 11. Objections to aqueous consolidation, § 12, 13, 14. Compression affects the action of fire on bodies, § 15, 16, 17.—Igneous consolidation of minerals prove from fossil wood, § 19.—From the flints in chalk, § 20.—from sandstone, § 21.—from the calcareous strata, § 23, 24, 25.—from the argillaceous, § 26, 27.—from the bituminous, § 28, 29.—from the saline, § 32. Salt mines in Cheshire. Trona of Africa, § 54, 35.
3. Position of the Strata.
Strata formed at the bottom of the sea, § 36. Apparent elevation not produced by the retreat of the sea, § 37.—Strata, horizontal, when formed, § 38, 39. Disturbance of the strata proved from their inclined position § 40, 41, 42.—from shifts, &c. § 42. Shifts of different dates, ib. Disturbance of the primitive strata visible at their junction with the secondary, § 43, 44. This disturbance produced by a force directed upward, § 45, 46. This force the effect of subterraneous heat, § 47, 48.
