423. The elements of the air, polarized to the highest degree by electricity, must combine, and this combination is the process of combustion. The final result of electrical tension is combustion of air. It is only, however, the two primary bodies that undergo combustion; the two constituent parts of the air must, therefore, be driven by electricity to their last extreme, even to the most perfect element of fire and the basic or terrestrial substance. The internal combination of both these primary or elemental bodies, or the product of this aerial combustion is next of all _water_. The termination of electrical tension in the air is rain. All rain is the extinguished function, the dying spirit of air. The two hostile principles are reconciled in water. Water accompanies every process of combustion. 424. By electricity the air was separated into the two inferior elements, into water and earth. At present, where the whole water and the whole earth has been precipitated from air, rain is certainly as a rule only water condensed and held in solution in the air. 425. The nitrogen gas is the residue of the primary rain. After the air has become sea by the combination of oxygen and hydrogen, it no longer creates water out of its own bulk, but now rederives it from the sea, and still but imitates its primary process in rain. 426. Were there merely solid land upon the planet, the oxygen pole would be evoked in the air, and the latter would be precipitated wholly as water. Were there merely water or sea upon the planet, the nitrogen pole would be evoked, and the air be wholly precipitated as earth. But since the two elements are constantly and alternately operating upon the air, so must at one time water, at another earth, be generated and precipitated from it. The earths in the act of falling down, or in precipitation, are the meteoric stones. They are only the after-births of the primary decomposition of air. 427. It can indeed be none other than carbonic acid, which is converted by decomposition into meteoric stones, or at least into the metals and earths which they contain. Sulphur must be regarded as the melting down of carbon and hydrogen. In the upper lighter regions of the air carburetted hydrogen gas may very well be present, and condense itself into meteoric stones. 428. The condensation must take place by means of electricity. The greater condensation or solidification, as well as the calefaction, results indeed first through the fall. 429. Their bursting is only conceivable when some hydrogen gas is in the meteoric stone, which gas, when submitted to the highest degree of heat, becomes finally fulminating gas and bursts the stone. 430. Meteoric stones are children of our planet, and not of the world-space. They are the antagonism of the water-formation or of rain.
