Historical Definition
Mercurialis seva is alum water.
Meaning
The complete expression receives its own material equivalent. A reader should not discard alum water and substitute ordinary mercury merely because the headword is mercurial in form. The definition does not specify a preparation or kind of alum.
Use in the Book
The neighbouring Mercurius compounds likewise require their particular definitions: one names a precipitated extraction, another a crystalline appearance, another a first being. Their shared vocabulary is not a substitute for those differences.
Places to Read
Mercurius Crystallinus. A repeatedly sublimed mercurial preparation characterised by crystal-like clarity.
Mercurius metallorum præcipitatus. A preparation specified by metallic extraction followed by precipitation.
Mercurius regeneratus. Regenerated mercury defined through its first being.
