in the City of London, Patent Agent, for the Invention of "A COMPOSITION
OR COMPOSITIONS TO BE USED AS A SUBSTITUTE FOR HOPS IN BREWING.".
A communication from A. Boehler and P. F. Quantin.

Sealed the 5th August 1856, and dated the 26th February 1856.
PROVISIONAL SPECIFICATION left by the said Richard Archibald Brooman
at the Office of the Commissioners of Patents, with his Petition, on the
26th February 1856.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention
for "A COMPOSITION OR COMPOSITIONS TO BE USED AS A SUBSTITUTE FOR HOPS IN
BREWING," (communicated to me by A. Boehler and P. F. Quantin, foreigners
residing abroad,) to be as follows:-
The Invention consists in a new composition or compositions, which the
Inventors term "lupuleid," to be used as a substitute for hops in brewing.
The lupuleid is manufactured in the following manner:-To one part by
weight of some resinous substance (preference being given to white Burgundy
pitch) broken into very small pieces, placed in a vessel of some material not
liable to be affected by the action of acid, add two parts by weight of nitric
acid. Apply heat from a slow fire. until the melted resin begins to distil and
give off gaseous bubbles, then remove the vessel from the fire. The resinous

page_text: substance continues to bubble, and falls over the side of the vessel on to a
wooden or enamelled receiver, where it cools and hardens. The whole is then
placed into a receiver and left to cool, and when cold, it is carefully washed to
remove all traces of nitric acid. The lupuleid is then dried in a stove, or by a
current of warm air or otherwise, and when quite dry, it is reduced to powder
and ready for use. To add to the bitter principle of lupuleid, I add to
every 1000 parts by weight of the white resinous substance about 10 parts
more or less of the resinous principle of aloes, which is prepared by first
reducing it to powder, then steeping or macerating it in cold water, and next
filtering it; the insoluble substance which remains is added to the Burgundy
pitch, and then proceed as before. By evaporating the liquid obtained by
filtration, a very bitter extract will be obtained, which may be added to the
lupuleid to increase at will its bitterness or the liquid obtained by filtration may
be added to the lupuleid. It has been found, that about 1 lb. of lupuleid will
go as far as ten times its weight of hops.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman in the Great Seal Patent
Office on the 25th August 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent Agent,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of February, in the year of our Lord
One thousand eight hundred and fifty-six, in the nineteenth year of Her reign,
did; for Herself, Her heirs and successors, give and grant, unto me, the said
Richard Archibald Brooman; Her special licence:.that I, the said "Richard
Archibald Brooman,' my 'executors, administrators, and trassigns, "or such
others as I, the said Richard Archibald Broomän; my 'executors, adminis
trators, and assigns, should.at any time.. agree with, and not 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:"A COMPOSITION OR COMPOSITIONS TO BE USED AS A SUB-
STITUTE FOR HOPS IN BREWING," (communicated to me by A. Boehler and P F
Quantin, foreigners residing abroad,) upon the condition' (amongst others) that
I, the said Richard Archibald Brooman,tiny executors or administrators, by

page_text: 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 Richard Archibald Brooman; 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:
I
...This Invention consists in a new composition or compositions, which the..
Inventors term "lupuleid," and which is for are intended, to be used as a sub-
stitute for hops.in-brewing.
The lupuleid is manufactured in the following manner:-To one part by
weight of some resinous substance preference-being-given to white Burgundy
pitch, broken into very small pieces and placed in a vessel made of a material
not liable to be affected by the action of acid (such as enamelled iron) are
added two parts by weight of nitric acid, of any suitable strength, and heat
is then applied to the mixture by a slow fire until the melted resin begins to
distil and give off gaseous bubbles, when the vessel is removed from the fire.
The resinous substance, still acted on by the acid, continues to bubble up, and
falls over the side of the vessel on to a wooden or enamelled receiver. The
mixture is again placed in the vessel and allowed to fall over as before; and
this may be done three or four times, as long as the acid continues to work
the resin and throw it over. The mixture is then poured out into another
vessel with a fresh supply of acid, in the same quantity as was first employed,
(or into the first vessel, after having carefully cleaned it from the acid first
used,) and is placed over a slow fire, when it bubbles over, all as before. The
whole is then placed into a receiver and left to cool, reduced to powder and
carefully washed to remove all traces of nitric acid (the presence of which may
be detected by the usual test paper). The "lupuleid" is then dried in a stove
or by a current of warm air, or otherwise, and when quite dry it is ready for
use, or it may be reduced to powder after being washed and dried.
To increase the bitter property of "lupuleid" for certain descriptions of
beverages, if desired, the inventors add to every 1000 parts by weight of the
resinous substance about 10 parts by weight (more or less) of the resinous
principle of aloes, which is prepared for the purpose by being first reduced to
powder, then steeped or macerated in cold water, and afterwards filtered; the
insoluble substance which remains is added to the Burgundy pitch or other
resinous substance used, which is then ready to be treated with nitric acid, all

page_text: as before described. By evaporating the liquid obtained by filtration, a very
bitter extract will be obtained, which may, if desired, be added to the
"lupuleid." It has been found, that about 1 lb. of "lupuleid" will go as far
as ten times its weight of hops.
And having now described the nature of the said Invention and in what
manner the same is to be carried into effect, I declare that I claim, the new
composition or compositions called "lupuleid," manufactured as herein-before
described, and intended to be used as a substitute for hops in brewing.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Twenty-third day of August, One
thousand eight hundred and fifty-six.
