Meaning
The four are earth, water, air and fire, named as constituents of the one natural subject and ensouled by fifth essence. Khunrath's argument requires the qualification: the elements as constituted in the catholic subject are not equivalent to bare elements proposed as an alternative starting material.
Use in the book
At p. 54 the elemental list completes the numerical unfolding begun with one crude Mercury. The pair and the triad do not disappear when the four are named. All remain in one natural subject, and the four are explicitly ensouled. They therefore provide another analysis of Magnesia's constitution, not a command to assemble four separately handled ingredients. The primary margin's Tetractys and its Latin equivalents relate this fourfold account to the number-language completed by the Denarius on the following page.
The objection from Bernard at pp. 64–652 supplies the negative limit. Khunrath anticipates an appeal to the Count's attack on bare elements as first matter and says it does not refute his Magnesia. He is not maintaining the view Bernard rejected. Instead, he cites the account of crude Mercury as a subject upon which Nature has already worked a little, composing and shaping it into a catholic mass. The subject has a definite outward form and remains imperfect, but is not a metal or mineral.
The distinction between a naturally composed whole and its analytic constituents is therefore indispensable. “Contains four elements” cannot be reversed into “any mixture of four elements is the due subject.” The ordering, animation and catholic condition have already been supplied by Nature. That is why the Artist begins from the thing rather than from a bare inventory of elementary names.
Elsewhere the text also distinguishes elemental fire from the essential fire associated with loosening metallic bodies. Such usages warn against making every occurrence of earth, water, air or fire an identical technical constituent. In particular, the pri-material water of Magnesia carries functions not established by the bare fact that common water is one of the four elements. The elemental account must be read within the larger demonstration rather than treated as its replacement.

Translation in this edition
The English preserves the four familiar element-names rather than converting them into a modern list of substances or states. “Bare” is decisive in the Bernard objection: Khunrath's reply concerns the absence of the appropriate natural composition and condition, not a denial that his subject includes four elements.
