any other drink but Lime-water, or water in which Lime-stone is immerged; their meat is nothing else but Fowl of several sorts, their recreations are many, but chiefly Hunting. This Relation amazed the Empress very much; for though in the World she came from, she had heard great reports of the Philosophers-stone, yet had she not heard of any that had ever found it out, which made her believe that it was but a Chymera; she called also to mind, that there had been in the same World a Man who had a little Stone which cured all kinds of Diseases outward and inward, according it was applied; and that a famous Chymist had found out a certain Liquor called Alkahest, which by the vertue of its own fire, consumed all Diseases; but she had never heard of a Medicine that could renew old Age, and render it beautiful, vigorous and strong: Nor would she have so easily believed it, had it been a medicine prepared by Art; for she knew that Art, being Natures Changeling, was not able to produce such a powerful effect; but being that the Gum did grow naturally, she did not so much scruple at it; for she knew that Nature's Works are so various and wonderful, that no particular Creature is able to trace her ways. The Conferences of the Chymists being finished, the Empress made an Assembly of her Galenical Physicians, her Herbalists and Anatomists; and first she enquired of her Herbalists the particular effects of several Herbs and Drugs, and whence they proceeded? To which they answered, that they could, for the most part, tell her Majesty the vertues and operations of them, but the particular causes of their effects were unknown; onely thus much they could say, that their operations and vertues were generally caused by their proper inherent, corporeal, figurative motions, which being infinitely various in Infinite Nature, did produce infinite several effects. And it is observed, said they, that Herbs and Drugs are as wise in their operations, as Men in their words and actions; nay, wiser; and their effects are more certain then Men in their opinions; for though they cannot discourse like Men, yet have they Sense and Reason, as well as Men; for the discursive faculty is but a particular effect of Sense and Reason in some particular Creatures, to wit, Men, and not a principle of Nature, and argues often more folly then wisdom. The Empress asked, Whether they could not by a composition and commixture of other Drugs make them work other effects then they did, used by themselves? They answered, That they could make them produce artificial effects, but not alter their inherent, proper and particular natures.
