Basil Valentine, who was one of the greatest alchemists of the 16th century, discovered many of the properties of the metal antimony, and prepared and examined many compounds of that metal; he made green vitriol from pyrites, brandy from fermented grape-juice, fulminating gold, sulphide of potash, and spirits of salt; he made and used baths of artificial mineral waters, and he prepared various metals by what are now called wet methods, for instance, copper, by immersing plates of iron in solutions of bluestone.
The most hidden corners of nature are investigated; chemistry separates material objects into their ultimate elements, and creates worlds of her own; alchemists enrich the province of physical science; the microscopic glance of a Schwammerdam surprises nature in her most secret operations.
Dr Porhoët, smiling shook his head. 'I don't think I shall ever do that now, he said. 'Yet he is the most interesting of all the alchemists, for he offers the fascinating problem of an immensely complex character. It is impossible to know to what extent he was a charlatan and to what a man of serious science.
The Alchemists are supposed to have been imbued with the desire and, to some extent, at least, were regarded as having the knowledge of how to make gold.
Then he had penetrated further, lower, beneath all that finished, material, limited knowledge; he had, perhaps, risked his soul, and had seated himself in the cavern at that mysterious table of the alchemists, of the astrologers, of the hermetics, of which Averroes, Gillaume de Paris, and Nicolas Flamel hold the end in the Middle Ages; and which extends in the East, by the light of the seven-branched candlestick, to Solomon, Pythagoras, and Zoroaster.
Oldbuck alone curled up his nose, and observed, that Miss Wardour's skill was something like that of the alchemists, for she had contrived to extract a sound and valuable moral out of a very trumpery and ridiculous legend. "It is the fashion, as I am given to understand, to admire those extravagant fictions for me, I bear an English heart, Unused at ghosts and rattling bones to start."
Warner's fate was inclusion in the number of astrologers and alchemists retained by the Duchess of Bedford, who also gave a place amongst her maidens to Sybill, to whom Hastings had proffered his devoted attachment, though he was already bound by ties of policy and early love to Margaret de Bonville.
And then after supper we will walk half-way home across that beautiful valley beautiful even in winter with my father and Walter, and count the stars, and take new lessons in astronomy, and hear tales about the astrologers and the alchemists, with their fine old dreams. Ah! it will be such a happy Christmas!
Time was when the alchemists thought they possessed the ne plus ultra of human knowledge, and that wisdom would die with them; yet their knowledge is now to chemistry what astrology is to astronomy. It is a superstition on whose claims no scientist would dare to risk his reputation.
He gave a history of the long dynasty of the alchemists, who spent so many ages in quest of the universal solvent by which the golden principle might be elicited from all things vile and base, Aylmer appeared to believe that, by the plainest scientific logic, it was altogether within the limits of possibility to discover this long-sought medium.
