page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
SANDERSON HALL, of the Cirens, Minories, in the City of London, Gentleman,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Second day of August, in the second year of "Her reign, did, for
Herself, Her heirs and successors, give and grant unto me, the said Samuel
Sanderson Hall,. Her especial licence, full power, sole privilege and authority,
that I, the said Samuel Sanderson Hall, my exors, admors, and assigns, or such
others as I, the said Samuel Sanderson Hall, my exors, admors, or assigns,
should at any time agree with, and no others, from time to time and at all
times during the term of years therein expressed, should and lawfully might
make, usc, exercise, and vend, within. England, Wales, and the Town of Berwick-
upon-Tweed, the Invention of "IMPROVEMENTS IN PRESERVING CERTAIN VEGE-
TABLE SUBSTANCES FROM DECAY," Communicated to me by. a certain foreigner
residing abroad; in which said Letters Patent is contained a proviso that I,
the said Samuel Sanderson Hall, shall cause a particular description of the
nature of the said Invention, and in what manner. the same is to be per-
formed, to be inrolled in Her said Majesty's High Court of Chancery, within six
calendar months next and immediately after the date of the said in part recited
Letters Patent, as in and by the same, reference being thereunto had, will
more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Samuel Sanderson Hall, do hereby declare the nature of the said Invention,

page_text: and the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, that is to say:-
The present Invention is communicated to me by Franz Moll, Esquire, of
Rotterdam, and consists of improvements on a former Patent granted to him
by His late Majesty William the Fourth, bearing date at Westminster, the
Nineteenth day of January, One thousand eight hundred and thirty-five, to which
a Specification was duly enrolled, wherein it was declared that the Invention
consisted in impregnating timber or wood with certain chemical products
called eupion and kreosot.
Now the object of the present Invention is to apply kreosot in combination
with water to impregnate wood or timber, in order to preserve the same from
dry rot or decay. The timber or wood is to be soaked in a solution of kreosot,
more or less time, according to the degree of saturation desired, and in order
to facilitate the process, heat is applied to the solution by steam pipes or other
suitable means. I generally employ large wooden tanks to contain the solution
and the wood or timber under operation, the size of which depends on the
quantity and description of wood to be operated on. The strength of the solu-
tion is not material, and I obtain kreosot in solution in water by means of
alkalies or other suitable materials.
Having thus explained the nature of the Invention, I would have it under-
stood that what I claim is, the application of kreosot in combination with
water for the purpose of preserving wood or timber from dry rot or decay.
In witness whereof, I, the said Samuel Sanderson Hall, have hereunto
set my hand and seal, this Second day of February, One thousand eight
hundred and thirty-nine.
