page_text: LETTERS PATENT to Charles Smith Roskilly, of Falmouth, in the County
of Cornwall, Brewer, for the Invention of "IMPROVEMENTS IN REFINING
MALT LIQUORS."
Sealed the 9th August 1861, and dated the 18th February 1861.
ROVISIONAL SPECIFICATION left by the said Charles Smith Roskilly.
at the Office of the Commissioners of Patents, with his Petition, on the
18th February 1861.
I, CHARLES SMITH ROSKILLY, of Falmouth, in the County of Cornwall,
Brewer, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN REFINING MALT LIQUORS," to be as follows:―
Instead of the usual mode of refining malt liquor by the use of isinglass
dissolved in sour beer with fish skins, which in practice is found very objec-
tionable, frequently spoiling the liquor, I use a compound or mixture of malt,
hops, the leaves of ground ivy, and nettles boiled in-water, and when cold I
add a small portion of the compound to the liquor to be refined.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
SMITH ROSKILLY, of Falmouth, in the County of Cornwall, Brewer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of February, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fourth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the said
Charles Smith Roskilly, Her special licence that I, the said Charles Smith
Roskilly, my executors, administrators, and assigns, or such others as I, the
said Charles Smith Roskilly, 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 REFINING MALT LIQUORS," upon the condition (amongst
others) that I, the said Charles Smith Roskilly, 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 immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Charles Smith Roskilly, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement (that is to say) :-
Instead of the usual mode of refining malt liquor by the use of isinglass
dissolved in sour beer with fish skins, which in practice is found very objec-
tionable, frequently spoiling the liquor, I use a compound or mixture of malt,
hops, the leaves of ground ivy, and nettles boiled in water, and when cold I
add a small portion of the compound to the liquor to be refined.
I make the said compound as follows:-To one gallon of ground ivy leaves
I add about fifteen gallons of water; to one Cornish bushel of nettles I add
about fifteen gallons of water; to ten pounds weight of hops I add about fifteen
gallons of water, and to half a pound weight of malt I add about fifteen

page_text: gallons of water. I boil the said mixtures together for about six hours, and
when cold I add a small portion of malt liquor thereto, thus forming the
improved compound, one pint of which to one hogshead of ale, beer, or porter
will make it as fine as wine, improve the flavour, and prevent it turning sour.
Having thus fully described the nature of the said Invention, and the
manner in which the same is to be performed, I desire it to be understood
that I claim as my Invention, and which to the best of my knowledge and
belief has not been hitherto used within the realm, the use of a compound
made, as herein described, for refining malt liquors.
In witness whereof, I, the said Charles Smith Roskilly, have hereunto
set my hand and seal, this Twelfth day of August, in the year of our
Lord One thousand eight hundred and sixty-one.
C. S. ROSKILLY. (L.S.)
