TO

Sir HANS SLOANE, Bart.

  First Physician in Ordinary to His MAJESTY; President of the ROYAL
  SOCIETY, and also of the College of Physicians.


_SIR_,

Your ready Condescension to peruse the following Treatise, and to see
the Experiments of my Liquor, both in regard to its bringing out,
and destroying Buggs; as also that of its no ways staining Furniture;
was to me the happy Presage of your Favour, and Approbation of my
Performances.

The Satisfaction of having this Treatise and Experiments approv’d by
You, the Best of Judges, was to me the greatest Honour I could wish
for; but the additional one, confer’d by your introducing me to the
_Royal Society_, and there having not only their unanimous Approbation,
but yours and their Thanks for my Discoveries and Intent of publishing
them, was beyond my Hopes, and a Pleasure so great, as to be past
expressing; in regard that it dissipates all my Fears for its Success,
and makes me justly hope it will meet with a candid Reception from, and
be of general Benefit to the Publick.

As to your Goodness, I must ascribe the happy Prospect of its proving
so, Gratitude obliges me in this manner to acknowledge it; and to be,

      _Sir_,
    _Your Much-Obliged_,
  _And Most Obedient Servant_,

      JOHN SOUTHALL.

  PREFACE.


_Being diffident of my own Performance, and desirous it should stand or

me to make my Application to that very Learned, truly Judicious and
commendably Curious Person to whom it’s dedicated: At the same time
determining, that if he approv’d of it, I would publish it; and if
he disapprov’d, that I would burn it. But it happily meeting his
Approbation, it now makes its Appearance in Print: Tho’ I must in
Justice to him acknowledge, it could not have so done so soon, nor
with such Embellishments, had he not only forwarded the Impression,
but directed and order’d the Copper-plate. As it has not only his
Approbation, but also, by his introducing it, the unanimous Concurrent
Approbation of (those great Encouragers of things useful) the Royal
Society; I hope it will not fail of meeting a kind Reception from the
Inhabitants in and about this Metropolis; by whom, as such a Treatise,
&c. was
