866. The elective affinities are based upon the polarizibility or transmutability of the Fluid and the Solid into the primary bodies. That is decomposed and combined, which during admixture maintains the animation in the strongest degree unto the origin. What cannot be so reduced, is precipitated, as is silex. The chemism is a bin-elementary process, and therefore constitutes the termination of this period of creation, or of the mineral kingdom. So soon as a tri-elementary process originates, the products pass over into a new kingdom. PART III. BIOLOGY--OF THE WHOLE IN SINGULARS. A.--_ORGANOSOPHY_. I.--ORGANOGENY. A. _Galvanism._ 867. If we take a retrospective glance at the _development_ of the planet, we find that it commenced with the simplest actions, and then assumed a more elevated character by gradually drawing together several actions and letting them work in common. In magnetism the earth-element alone was active, and this having freed itself from the other elements by crystallization, asserted itself as a particular form upon the planet. By this single act of the planet, an extensive series of positions or numbers originated, which may be called _mineral individuals_. 868. Up to the formation of the solar system or of the planet, the character of creation is _analytic_. The three primary ideas emerged from each other as gravity, light and heat, and appeared as fire. These three united actions emerged again from each other and became air, water and earth, which together make up the planet. This was therefore the descending creation. But from and after this period, the character of the development of the planet becomes _synthetic_, for the divided elements again united with each other. By synthesis only or by combination of the elements does the planet progressively advance, and by it only does it divide into lesser planetary masses or bodies, called _individuals_. This is the ascending creation. 869. To the earth-element, in which the active magnetism is isolated, comes the element-water; and by the identification of both into _one_ body, a new process is evolved, which we have recognized by the term _chemism_--salt. Then the earth-element combines with air and becomes an Inflammable, in which the process is likewise extinguished and only a dead product is left--the Inflammable. Then it combines with fire and is converted into ore. There never originates therefore from the twofold combination of the earth-element with any other element, but one product, that namely in which the Earthy obtains the preponderance, or a mineral. 870. _Two_ elements only belong to the essence of chemism, and they indeed are the two lowest, the elements carbon and oxygen, both being reduced to their primary condition, i. e. to that of an alkali in natron, and an acid in the hydrochloric or that of common salt.
