Terrestrial Part

of the physical description of the world.

In the endeavor to master an immense material of the most diverse objects—that is, to arrange the phenomena in such a sequence that insight into their causal connection is facilitated—the presentation can only grant oversight and luminous clarity if the specific details, especially in the hard-won and long-researched field of observation, are not removed from the higher perspectives of cosmic unity. The terrestrial sphere the realm of the Earth, as opposed to the uranological the realm of the heavens or stars, is divided into two sections: the inorganic and the organic domains. The former encompasses: the size, shape, and density of the earth's body; internal heat; electro-magnetic activity; the mineral constitution of the earth's crust; the reaction of the planet's interior against its surface—acting dynamically through tremors and chemically through stone-forming and stone-altering processes; the partial covering of the solid surface by liquid, the sea; the outline and
