in Aqua Regia, it presently takes all the Gold from it's former
Solvent, keeping it perfectly dissolved and suspended, without the
least Precipitation; and becomes of a yellow Colour: The AETHER,
thus saturated with the Gold, does not mix with the Aqua Regia,
but may readily be separated from it by simple Decantation, and
thus a true and safe _Aurum potabile_ is readily prepared for
those who want such a Medicine. The Union of these two Substances
is very remarkable, one being the heaviest solid Body we know, the
other the lightest Liquid.

The AETHER is remarkably cold, when dropped upon the Hand, and it
affects the thermometer in an extraordinary Manner; for if the
Ball of either a Mercurial or Spirituous Thermometer be immersed
in it, the Spirit or Mercury immediately sinks considerably, tho'
both the AETHER and the Thermometer have stood a sufficient Time
together to be brought to the temperature of the Room, before the
Experiment was made. The Thermometers dipt into Water, or Spirit
of Wine, in the same Manner, suffer not the least Alteration.

They who chuse to see a further Account of the singular Effects
which this curious Fluid produces, may peruse what Doctor
_Frobenius_, a _German_ Chemist, has published concerning it, in
the Philosophic Transactions for the Years 1733 and 1741.

But the most valuable Qualities of the AETHER are it's _medicinal_
ones; it having been found by repeated Experience to be an
excellent Remedy in most _nervous Diseases_; particularly in FITS
of all sorts, whether _Epileptic, Convulsive, Hysteric,
Hypochondriac, or Paralytic_: In habitual HEAD-ACHES, GOUT,
