_How Gold may be rendred Volatile, so as to be sublimed into a
salutary Medicine._
Dissolve as much Common Salt in _Aq. Fortis_ as you can, in this _Aq.
Regia_ dissolve Sol, which precipitate with Spirit of Urine. In Sand
abstract all the Phlegm to a dry Salt; if afterward you augment the
Fire, the Coagulated Spirit of Urine will carry up with it self part
of the purest _Sol_ in the form of a Red Salt. This Salt will yield
very profitable Fruit in Medicine. The Dose is from three, six, eight,
to twelve Grains; endued with power of expelling Sweat and Urine, and
famously conducent against the Stone and Gout. Also since this Salt
is void of any loathsome Taste, it may securely and commodiously be
administred as a Cathartick to Infants, and Women with Child.
