Pyruacoras saith: We must affirm unto all you seekers after this Art that the Philosophers have treated of conjunction (or continuation) in various ways. But I enjoin upon you to make quicksilver constrain the body of Magnesia, or the body Kuhul, or the Spume of Luna, or incombustible sulphur, or roasted calx, or alum which is out of apples, as ye know. But if there was any singular regimen for any of these, a Philosopher would not say so, as ye know. Understand, therefore, that sulphur, calx, and alum which is from apples, and Kuhul, are all nothing else but water of sulphur. Know ye also that Magnesia, being mixed with quicksilver and sulphur, they pursue one another. Hence you must not dismiss that Magnesia without the quicksilver, for when it is composed it is called an exceeding strong composition, which is one of the ten regimens established by the Philosophers. Know, also, that when Magnesia is whitened with quicksilver, you must congeal white water therein, but when it is reddened you must congeal red water, for, as the Philosophers have observed in their books, the regimen is not one.* Accordingly, the first congelation is of tin, copper, and lead. But the second is comf posed with water of sulphur.* Some, however, reading this book, think that the composition can be bought. It ‘jmust be known for certain that nothing jof the work can be bought, and that ithe science of this Art is nothing else than vapour and the sublimation of water, with the conjunction, also, of ‘quicksilver in the body of Magnesia; ¢ jbut, heretofore, the Philosophers have idemonstrated in their books that the impure water of sulphur is from Ysulphur only, and no sulphur is produced without the water of its calx, and of quicksilver, and of sulphur.
