SOME
EXPERIMENTS
CONCERNING
MERCURY.
They who by Experiments have most diligently enquired into the Origin of Bodies, and their peculiar Powers and Properties, are the only Men who have discovered sure Methods of acquiring a true Knowledge of these Things: And whenever the Lovers of natural Knowledge enumerate the Instruments of this Science, they universally agree that Chemistry has done the greatest Service, in most industriously promoting such Discoveries: And when they come carefully to examine the most celebrated Writers in this Art, they plainly perceive, that the most ancient Alchemists far surpassed the rest in their Accounts of the Nature of Things. Of this Geber is an Instance, and the Writers nearest to him; for they are content to describe, in the plainest manner, such Things only as they had discovered by their Art; to improve which was their great Application, having no other Design in view. And indeed no other Men whatever have so strictly and obstinately labour’d in the Search after natural Things, or have taken such great Pains to turn Matter, thro’ all the various Modes of Enquiry, as the Alchemists. This is what will be readily granted by all those who read the Hermetic Writers, when they openly relate common Discoveries: But, on the contrary, when these Writers treat of the Grand Arcanum (or Secret of the Wise) they are accused of making a bad Use of their Knowledge, out of a Desire to conceal it, as if they intended, on that Occasion, not to be understood. They are said to deal in Paradoxes, to write in a strange manner, perfectly foreign to all that is known, and their Style is swell’d with hyperbolical and sublime Expressions; which makes them be exploded as Men out of their Senses, fabulous, false, and Liars: For whilst they affect to write in the gravest Terms, and are rich in Promises, they so cover the Thing they are treating of in Obscurity and Darkness, that they seem unwilling the Secret should be reveal’d. And on this account it is, that very many wise Men are of Opinion, that what the Alchemists promise, is a Thing impossible both to Nature and Art, and therefore count them unworthy the Perusal of Philosophers, as well as undeserving of the Name. But it is a Maxim, That it is safer to credit an Artist in his own Art, than one that is an utter Stranger to it; and consequently it is rash to condemn what the Alchemists have defined to be possible; especially, since these Chemists openly declare, that their Writings are to be weighed in the Balance of the most certain Laws of Nature, which have been discovered with the greatest Evidence by the Events of Things; (that is, by exact and repeated Experiments) and they desire not to be credited, whenever they produce any Thing contrary to the Powers of Nature truly known by Experiments. Moreover they alledge, that they express themselves in such an obscure manner, only to keep profane Persons away from their Mysteries, which are unfolded to such as are initiated in them; and so that it was necessary that Things strange, obscure, and often false, should be mixed and interpolated with what is sincere, clear, and true in their Writings.
