and that is best of all, and most securely performed by the Operation of our Universal Medicament, by which they are found to be notably recreated. For as soon as this more than perfect Medicine hath driven the Morbifick Evil from the Seat it occupies, then immediately it infuseth the lost Sanity, and that only from the Harmony, or Sympathy it self, which the Vital Spirits, and this Medicine, have mutually in themselves. Wherefore, it, by the Adept, is called the Mystery of Nature, and the Defensive of old Age, against all Diseases. Which, I fay, even in a most pestilent Season, most full of contagious Diseases every where raging, makes of man a Salamander, bearing such Epidemical Plagues of Heaven displeased, until the utmost term of his Life be expired. Physician As far as I, beloved Friend, can understand, this Medicine makes not for the Emendation of depraved Humours, but is chiefly conducent for the recreation of the Vital Spirits. Besides, among practical Chimists, this Secret is taught, viz. that by the Spayrick Art, it may be commonstrated, how the pure should be separated from the impure, and by the same, how the Immature are rendred mature, and how the Bitter are corrected into sourish, and the sourish into Sweet, and the Sharp into Gentle, and the Gentle into Sharp; and the Acid into Sweet, and the Sweet into Acid. Also this Laudable Medicine of Philosophers, according to my understanding, cannot prolong Life, beyond the term prefixed from above, but only preserve from the Effect of all Venimous, or otherwise mortiferous Diseases: and so it is certainly true, as is commonly believed, that the prolongation of Humane Life depends, on the Will of the Omnipotent God only. But, omitting these, I would here ask this one Question. Whether by the use of this Universal Medicine, the pristine Nature of Man may be converted into New, so as a Slothful Man may degenerate into a Diligent, or stirring Man, and a Man, who before was by Nature Melancholy and Sad, afterward became Jovial, Chearful, and full of Joy, or like alterations, reformations, permutations, or vicissitudes happen in the Nature of Man?
