An Account of the Extraordinary Medicinal Fluid, called Aether‪.‬

It is a kind of Ethereal oil, produced by the Decomposition of the Vinous Spirit by Means of the Vitriolic Acid, and differs essentially both from Vinous Spirits and Essential Oils in several Respects, tho' it agrees with them in some, as will appear hereafter: But as the Vinous Spirit may be decomposed by means of all the three Mineral Acids, viz. the Vitriolic, the Nitrous and the Marine, and as these all act differently on the Spirit, they will, of Course, produce three different Kinds of Aether, which, from the Name, of the Acid employ'd in making them, are term'd Marine, Nitrous, or Vitriolic: the last only is the Kind here understood, it's Properties being more singular and extraordinary, and, as an Aether, more perfect than either of the others; the Reason of which seems to be, that the Vitriolic Acid is a much stronger Agent on the Spirit, and more perfectly decomposes it, than either the Nitrous or Marine.
