After salutations ended, his new Guest, with great Reverence, asked, whether he might have freedom to come to me; because for the Pyrotechnick Art sake, he could not, nor was he willing to pass by the Door of my house; adding, that he had not only thought to have made use of some Friend to come to me, but had also read some of my little Treaties, especially that, which I published against D. Digbies Sympathetick Powder, in which I discovered my doubt of the true Philosophick Mystery. Therefore, this occasion being taken, he asked me, whether I could believe, that place was given to such a Mystery in the things of Nature, by the benefit of which a Physician might be able to cure all Diseases universally, unless the Sick already had a defect either of the Lungs, or Liver, or of any like noble Member? To which I answered. Such a Remedy is exceeding necessary for a Physician, but no man knows, what and how great are the Secrets yet hidden in Nature, nor did I ever, in all my Life see such an Adept Man, although I have read and perused many things, touching the verity of this thing, or Art, in the Writings of Philosophers. I also enquired of him, whether he (speaking of the Universal Medicine) were not a Physician? But he answering by denyal, professed, that he was no other than a Melter of Orichalcum, and that in the Flower of his years, he had known many things, from his Friend, rare to the Sight, and especially the way of Extracting Medicinal Arcanums by the force of Fire, and that for this very cause, he was a Lover of this so noble Science of Medicine. Moreover, long after other discourses, touching Experiments in Metals, made by the violence of Fire, Elias the Artist spake to me thus; Do not you know the Highest Secret, when it is offered to your sight, viz. the Stone of Phylosophers, you having read in the Writings of many Chymists most excellent, touching the Substance, Colour, and strange effect of the same? I answered, not at all; except what I have read in Paracelsus, Helmont, Basilius, Sandivogius, and like Books of Adept Phylosophers extant. Nevertheless, I think, I am not able to know the Phylosophick Matter, whether it be true, or not, although I should see it present before me.
