page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Fergusson Wilson in the Great Seal Patent Office
on the 10th July 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
FERGUSSON WILSON, of Belmont, Vauxhall, in the County of Surrey, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of January, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said George Fergusson Wilson, Her special licence that I, the said
George Fergusson Wilson, my executors, administrators, and assigns, or such
others as I, the said George Fergusson Wilson, my 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 "IMPROVEMENTS IN TREATING BURMESE AND SUCH LIKE PRETROLEUM
AND THEIR PRODUCTS," upon the condition (amongst others) that I, the said
George Fergusson Wilson, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Furgusson Wilson, 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 :-
"The nature of my Invention consists in the distillation of Burmese and such
like petroleum and their products in a vacuum or partial vacuum.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
Heretofore Burmese and such like petroleum and their products have been
distilled by the aid of ordinary steam, superheated steam, and by fire heat, but
I have discovered that such descriptions of petroleum and their products may
be more advantageously distilled by the aid of vacuum, and I prefer to employ
vacuum apparatus, such as is used in boiling sugar in vacuum pans, applying,

page_text: however, a refrigerator and receiver between the boiler or still and the air
pump or vacuum apparatus. The boiler or still I prefer to heat by means of
a steam coil or steam jacket. When separating the lighter and more volatile
products I surround the refrigerator with as cold water as may be; by this
means the lighter products are more effectually condensed.
This Invention is not only advantageous in treating the crude Burmese and
such like petroleum, but also the products thereof which have been obtained
by previous distillation.
In witness whereof, I, the said George Fergusson Wilson have hereunto
set my hand and seal, this Ninth day of July, in the year of our Lord
One thousand eight hundred and fifty-seven.
Witness,
JNO. ALCOCK.
