QUARTA PARS

In which many excellent and useful secrets are revealed, serving the convenience of the Fatherland, and various methods are taught for the preparation of effective condiments derived from metals and intended for medical use, as well as the creation of golden potions.

With an attached treatise manifesting my laboratory, in which wondrous secrets, most useful to everyone and hitherto unknown, will be taught and demonstrated for the benefit of the Human Race and the public good.

In honor of God, and for the benefit of the Fatherland, the work is written and brought to light.
