The Summary of Physics Restored

52Although the elements that nature the modeller uses in her mixtures and in shaping bodies cannot be detected before mixture, once the work is finished and the compound perfected its parts may be called by the same names, since they correspond by a certain proportion to the world's parts and are in a way analogous. One may call the more solid parts earth, the moister parts water, the spiritual parts air, and innate heat nature's fire. The hidden and essential powers may aptly be called celestial and astral natures, or quintessence. In this way every compound will by analogy glory in the name microcosm.
