435. During every solution the two principles of water enter into a state of tension with each other, as the two aerial principles do in electricity. This tension is established by that which is to undergo solution; for everything so circumstanced is polar towards water. During every solution the oxygen is elevated in its pole, and the hydrogen likewise. If the solution be very heterogeneous, they separate, the water is decomposed. In the pure process of solution the water simply abides in a state of tension; if each aqueous principle is actually and independently self-evolved, chemistry then originates; but of this we shall discourse in the sequel. The process of solution may be characterized as the equilibrium of the process of tension between the object that is to undergo solution and the solvent, and between the two principles of the latter, whereby separation is not thus attained. As electricity finally strikes out into the process of combustion, so does that of solution into the chemical. 436. Solution is in essence like electricity. Solution is an electrical tension between oxygen and carbon; electricity is a process of solution between oxygen and nitrogen, a process of tension without separation of principles. Air and water are in a state of constant tension towards each other; and hence therefore result the constant evaporation and the clouds. 437. What lightning is in the air, namely formation of water, that is chemistry in water. The salt in the sea is what the clouds are in the air. Two electrical clouds are what two salts are in the water. Rain is the imitation of the creation of water. Precipitation of salt is the imitation of the creation of earth. 4. _Functions of the Earth._ CRYSTALLIZATION. 438. The earth-element is the highest result of combustion in creation, the highest fixation of æther. The earth is the æther represented as centre in the Material, or it is the identification of all polar binary division in the Terrestrial, independently of oxydation; therefore its parts are motionless, be they dust or compact masses. The earth is the corporeal gravity, the substance as a perfectly simple position without emergence out of itself, the 0, the terrestrial monas. The earth is consequently the heaviest and densest element, and is that which must include the middle point of our own and every planet. 439. In the middle of the planet there is only earth, and nothing else; the middle is not hollow, does not contain any central fire as has been imagined, nor air, and the science of Geogeny will show that no metal also could be contained in the interior of the earth. 440. In the air both material principles are only associated with each other, in water they are mixed, but in the earth identified, blended together.
