Introduction -- p. 79-83. A descriptive delineation of the world embraces the whole universe ([Greek words]) in the celestial and terrestrial spheres. Form and course of the representation. It begins with the laws of gravitation, and with the region of the remotest nebulous spots and double stars, and then, gradually descending through the starry stratum to which our solar system belongs, it contemplates this terrestrial spheroid, surrounded by air and water, and finally, proceeds to the consideration of the form of our planet, its temperature and magnetic tension, and the fullness of organic vitality which is unfolded on its surface under the action of light. Partial insight into the relative dependence existing among all phenomena. Amid all the mobile and unstable elements in space, 'mean numerical values' are the ultimate aim of investigation, being the expression of the physical laws, or forces of the Cosmos. The delineation of the universe does not begin with the earth, from which a merely subjective point of view might have led us to start, but rather with the objects comprised in the regions of space. Distribution of matter, which is partially conglomerated into rotating p 17 and circling heavenly bodies of very different density and magnitude, and partly scattered as self-luminous vapor. Review of the separate portions of the picture of nature, for the purpose of explaining the reciprocal connection of all phenomena. I.

Form of the earth, its mean density, quantity of heat, electro-magnetic activity, process of light -- p. 154-202. b. Vital activity of the earth toward its external surface. Reaction of the interior of a planet on its crust and surface. Subterranean noise without waves of concussion. Earthquakes dynamic phenomena -- p. 202-217. c.

Geognostical classification of rocks into four groups. Phenomena of contact. Fossiliferous strata; their vertical arrangement. The faunas and floras of an earlier world. Distribution of masses of rock -- p. 247-384. f. Geognostical epochs, which are indicated by the mineralogical difference of rocks, have determined the distribution of solids and fluids into continents and seas. Individual configuration of solids into horizontal expansion and vertical elevation. Relations of area. Articulation. Probability of the continued elevation of the earth's crust in ridges -- p. 284-301.
