Year: 1832

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HOWARD. KYAN, late of South Row, Euston Square, but now of Gillingham
Street, in the County of Middlesex, Esquire, send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Thirty-first day of March, in the second year of His reign, did,
for Himself, His heirs and successors, give and grant unto me, the said
John Howard Kyan, His especial licence that I, the said John Howard
Kyan, my exors, adññors, and assigns, or such others as I, the said John
Howard Kyan, my exors, adññiors, 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, use, exercise, and vend, within
England, Wales, and the Town of Berwick-upon-Tweed, my Invention of
". A NEW MODE OF PRESERVING CERTAIN VEGETABLE SUBSTANCES FROM DECAY;" in
which said Letters Patent is contained a proviso obliging me, the said John
Howard Kyan, by an instrument in writing under my hand and seal, parti-
cularly to describe and ascertain the nature of my said Invention, and in what
manner the same is to be performed, and to cause the same to be inrolled in
His 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.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
John Howard Kyan, do hereby declare the nature of my said Invention to
consist in destroying the tendency of certain vegetable substances to decay by
submitting that matter contained in them which most promotes it to the action
of deutochloride of mercury; and in further compliance with the said proviso,
I, the said John Howard Kyan, do hereby describe the manner in which my
said Invention is to be performed or carried into effect, by the following
description thereof, that is to say :-
Having prepared or constructed a large tank or reservoir of wood or other
suitable material, I fill it about two thirds full of deutochloride of mercury, or
as it is more commonly called corrosive sublimate, dissolved in hot or cold
water, or both, in the proportion of one pound of corrosive sublimate to five
gallons of water, and into the liquid I put the vegetable substances to be acted
upon, and keeping them completely covered by the liquid, steep them, for various
periods from fourteen to twenty-one days, according to the nature of the sub-
stances to be acted upon. The certain vegetable substances alluded to in my
said Patent are as follows (that is to say) :-all kinds of wood or timber used
for ship or other building, as also for carpenters, wheelwrights, turners, and
cabinet work, and these will require to be steeped in the liquid from fourteen
to twenty-one days, according as the wood is more or less porous and difficult
of entrance for the liquid, the most porous requiring the least time.
Now, whereas I claim as my Invention, preserving from decay the certain
vegetable substances herein-before described by immersing and saturating, or by
steeping or soaking the same, in or with a solution of corrosive sublimate and
water; and such my Invention being, to the best of my knowledge and
belief, entirely new and never before used within that part of His said
Majesty's United Kingdom of Great Britain and Ireland called England,
His said Dominion of Wales or Town of Berwick-upon-Tweed, I do
hereby declare this to be my Specification of the same, and that I do verily
believe this my said Specification doth comply in all respects, fully and without
reserve or disguise, with the proviso in the said herein-before in part recited
Letters Patent contained; wherefore I do hereby claim to maintain exclusive
right and privilege to my said Invention.
In witness whereof, I, the said John Howard Kyan, have hereunto set my
hand and seal, this Twenty-eighth day of September, in the year of our
Lord One thousand eight hundred and thirty-two.
JOHN HOWARD (L.s.) KYAN.
