Transcribed by David Ross <davidross@despammed.com> from an undated edition, c. 1761. Project Gutenberg E-Text of An Account of the Extraordinary Medicinal Fluid, called Aether. By Matthew Turner (d. 1788?) AN ACCOUNT OF THE EXTRAORDINARY MEDICINAL FLUID, CALLED AETHER. By M. TURNER, SURGEON, IN _LIVERPOOL._ LONDON: Printed by J. WILKIE, at the Bible in St. Paul's Church-yard. The Publisher of the following short Account of the AETHER having prepared, and successfully made Use of it in his private Practice, for several Years, has at length determin'd to endeavour to extend it's Utility, by thus making it public; as he knows of no one who has ever published it's _medicinal virtues_; or offered it to Sale in it's _Perfection_; or given the Criteria by which they who are unacquainted with it might distinguish the _Genuine_ from the _Spurious_: And he doubts not but every candid Person who examines it, will agree with him, That it carries with it the strongest Marks of a valuable Addition to the _Materia Medica_, and therefore ought to lie no longer in Obscurity. AN ACCOUNT OF THE AETHER, _&c._ This truly extraordinary Chemical Preparation is not a new Discovery, having been known and esteemed, as a valuable Curiosity, by many of the greatest Chemists and Philosophers, both Ancient and Modern; particularly by Sir _Isaac Newton_ [Footnote: Quere 31st, at the End of his Optics.], and the Honourable Mr. _Boyle_ [Footnote: Treatise on the Producibleness of Chemical Principles.], who both mention it in their Works, tho' not by this Name: And therefore before any Thing is said of it's Virtues as a Medicine, it may not be improper to explain the Nature of it, and enumerate a few of it's remarkable Properties, considered as a Curiosity in Chemistry, in which Light chiefly it has hitherto been view'd by those who have been acquainted with it.
