Astrologers in their Demonology profess to be able to ascertain the characters and seals of spirits,[10] and according to the Cabalists, tables are given of many of these in their books, in the so-called Theban Alphabet; in characters of Celestial Writing; in that called Mallachim; or in the writing called Passing the River.

They affect to have suitable bonds by which spirits can be bound, invoked, or cast out.

Of Necromancy they pretend to two kinds, one of which is raising the body of a deceased person, which it is said cannot be done without blood;—the other sciomancy, which is the production of a mere shade or shadow.

The exorcisms and conjurations of Magicians are so audaciously profane and blasphemous as to be unworthy of even a passing notice.

ALCHEMY.

We shall now proceed to consider Alchemy, another but very different chimerical pursuit, which was early cultivated in the East, and is generally ascribed to Hermes Trismegistus, although its more enthusiastic admirers pretend to trace a knowledge of it to Adam. From the earliest periods of history man was acquainted with gold, silver, and other metals, with bitumen, sulphur, sea salt, sal-ammoniac, gums, and resins, together with other varieties of substances and liquids common to modern chemistry. For the compounding and heating of certain of these materials a multiplicity of means were adopted requiring furnaces, crucibles, and distillatory apparatus. The first workers in these experimental operations formed a body of investigators into the nature and properties of all manner of substances, whether animal, vegetable or mineral, the members of which were distinguished as adepts, alchemists, and later in their career as common chemists. The most esteemed branch of the art however was Alchemy, a pseudo-science which ultimately took three forms. First, the Hermetic Art for the discovery of the Philosopher's stone; and the Alkahest, or universal solvent;—Second, a Medical Alchemy;—and Third, a Theological Alchemy pretending to conceal divine mysteries under an allegorical form, treating of the spiritual while apparently describing alchemical discoveries.

Our principal business, however, is with the so-called Hermetic Philosophy, treating of vaunted methods of transmuting the base metals into gold. It is doubtful whether this particular delusion of the adepts can be referred to a date earlier than the 8th century, but even then we cannot refrain from surprise at the fallibility of the human intellect, which could be swayed by a belief in the pretended lapis philosophorum for upwards of ten centuries. It was believed to be so secret and rare that its possession was never ascribed at any time to more than two or three favourite adepts, who transmitted it to some single favoured individual after his taking the sacrament, and going through certain prescribed religious ceremonies, preparatory to being entrusted with a verbal recipe for the composition of a peculiar smelling red powder, of which it was affirmed that when projected on heated mercury or any solid metal, it would at once change it into pure gold. Ashmole gravely assures us that Dr. John Dee and his associate Kelly, having in some way procured this precious substance, Kelly—to use Ashmole's own words—"made projection with one small grain thereof, in proportion no bigger than the least grain of sand, upon one ounce and a quarter of common mercury, and it produced almost an ounce of pure gold." With equal simplicity and earnestness, Ashmole asserts that this same Kelly was often seen to make these extraordinary transmutations,—"and in particular (he adds) upon a piece of metal cut out of a warming-pan, and without touching or handling it, or melting the metal, only warming it in the fire, the elixir being put thereon, it was transmuted into pure silver. The warming-pan and this piece of it, was sent to Queen Elizabeth by her Ambassador who then lay at Prague, that by fitting the piece into the place whence it was cut, it might exactly appear to be once part of the warming-pan."

Among the adepts there were no doubt a select few who employed themselves in their prolonged labours in all sincerity, and who were not unfrequently repaid with remarkable, and unexpected results. Brass, being the result of copper combined with zinc, would appear a singular transformation. Many stones, or more properly, ores, would yield sulphur and metals; sulphur would be found apparently to dissolve iron; and certain salts, when distilled, would yield corrosive acids. Alchemy thus presented to the ancient adepts many of the ordinary wonders of modern chemistry; in short, the latest adept of the present century is no other than an unlettered chemist. It was peculiar to the Alchemists to treat all their operations as secrets; which, when recorded, were described partly by symbols and partly in a novel nomenclature, invented to conceal their mysteries from vulgar gaze or imitation. Thus, to prepare the philosopher's stone, we have merely to—"Take of moisture, an ounce and a half; of meridional redness, that is the soul of the sun, a fourth part, that is, half an ounce; of yellow seyr, likewise half an ounce; and of auripigmentum, a half ounce; making in all three ounces. Know that the vine of wise men is extracted in threes, and its wine at last is completed in thirty." To the incredulous in these matters, Ashmole offers the admonition that, he knows "Incredulity is given to the world as a punishment!" However, when the Alkahest, or pretended Universal Solvent, was alluded to by the modern chemist Kunckel, he could not refrain from incredulously enquiring—"If it dissolves all substances, in what vessel can it be contained?"

Alchemical writings are very numerous, it might be impossible to procure a complete bibliographical list of them, but they may be estimated at from 3000 to 4000 works, and an astonishing number of manuscripts. Their authors indulge in such terms as the Ph[oe]nix, to indicate the quintessence of Fire; Realgar, for the fume of minerals; Guma, also Luna Compacta, for quicksilver; Hadid, for iron; Aurum potabile, for liquor of gold; Anathron, for saltpetre; Malek, for salt; Terra fidelis, for silver; Tinkar, for borax; and in a similar strain for all matters and operations; so that Dr. Johnson was justified in deriving the word Gibberish from the mysterious jargon employed by Geber, a celebrated Alchemist; who has, nevertheless, been appropriately styled the Pliny of the 8th century.

Weidenfeld, in an Alchemical Treatise, published in 1685, addressing students, says:—
