TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
FERGUSSON WILSON and GEORGE PAYNE, of Belmont, Vauxhall, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of April, in the year of our Lord One
thousand eight hundred and fifty-five, in the eighteenth year of Iler reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
George Fergusson Wilson and George Payne, Her special license that we, the
said George Fergusson Wilson and George Payne, our executors, administra-
tors, and assigns, or such others as we, the said George Fergusson Wilson
and George Payne, our executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "AN IMPROVEMENT IN
ORNAMENTING GLASS," upon the condition (amongst others) that we, the said
George Fergusson Wilson and George Payne, by an instrument in writing
under our hands and seals, or under the hand and seal of one of us, should
particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be filed in
the Great Seal Patent Office within six calendar months next and immediately
after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Fergusson Wilson, on behalf
of myself and the said George Payne, do hereby declare the nature of
the said Invention, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement
thereof, that is to say:-
This Invention consists of crystallizing fatty acids on the surface of glass or
between two surfaces of glass.
Having thus stated the nature of our said Invention, we will proceed
more fully to describe the manner of performing the same. We find that
the best result is obtained by previously warming the glass vessel to be
coated beyond the melting point of the fat acid used, in a steam closet or
oven, or in any convenient way. The glass vessel should then be filled
.

gradually until crystals appear forming on the inner surface of the glass.
The glass vessel should then be cooled rapidly by dipping in cold water, and
the excess of fat acid emptied out. Different appearances may be obtained
from the same fat acid by varying the time of cooling.
In witness whereof, I, the said George Fergusson Wilson, have hereunto
set my hand and seal, this Eleventh day of October, in the year of our
Lord One thousand eight hundred and fifty-five.
o Witness,
