Historical definition
Sulphur rerum is often taken to mean the quintessence of things.
Meaning
Often records a recurrent usage without making it universal. The headword’s sulphur can name the quintessence of the thing under discussion, rather than always referring to the mineral named simply as sulphur.
Use in the book
Quintessentia describes spiritual matter extracted corporeally from living things and raised toward purity by removing impurities. The cross-reference gives the reader a substantive account of the target concept. It also makes clear why identifying this sulphur requires the subject and context of the passage.
Resina terræ offers a contrasting local gloss: there the dictionary directly equates a compound name with sulphur. The present entry moves the other way, using sulphur as a name for quintessence. The direction of each definition matters.

In this edition
The qualifier rerum and the usage marker often are both retained. They keep the broader interpretive sense distinct from an unrestricted modern chemical equation.
