page_text: Invention for "IMPROVEMENTS IN THE PRODUCTION OF CITRIC ACID, TARTARIC
ACID, AND ALCOHOL," to be as follows:-
Our Invention or discovery relates to the treatment of the plant
known in Africa as the tamarinha for the production of citric acid,
tartaric acid, and alcohol. The plant is cut preferably when in a green
state, and is subjected to pressure to extract the juice or sap therefrom,
which is afterwards operated upon by the usual appliances or machinery
by which such acids and alcohol are generally made. The plant may
however be collected when in a full grown state, or when in flower or
in fruit (berry), and then be operated upon either by pressure or by
boiling or steaming; but the yield of acid and alcohol will not be so
large in proportion to the quantity of plant operated upon as from that
in a green state.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Antonio de Saldanha Albuquerque e Castro, Condi
de Penamacor, Antonio Paes de Sande e Castro, and Thomas Smith
Hopcraft in the Great Seal Patent Office on the 19th January 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ANTONIO
DE SALDANHA ALBUQUERQUE E CASTRO, Condi de Penamacor, ANTONIA
PAES DE SANDE E CASTRO, both of Lisbon, in the Kingdom of Portugal,

send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her

our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto us, the said Antonio de Saldanha Albuquerque e
Castro, Antonio Paes de Sande e Castro, and Thomas Smith Hopcraft,
Her special licence, that we, the said Antonio Saldanha Albu-
querque e Castro, Antonio Paes de Sande e Castro, and Thomas Smith
Hopcraft, our executors, administrators, and assigns, or such others as
we, the said Antonio de Saldanha Albuquerque e Castro, Antonio

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

condition (amongst others) that we, the said Antonio de Saldanha
Albuquerque e Castro, Antonio Paes de Sande e Castro, and Thomas
Smith Hopcraft, or one of us, our executors or administrators, by an
instrument in writing under our, or one of our 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

NOW KNOW YE, that we, the said Antonio de Saldanha Albuquerque
e Castro, Antonio Paes de Sande e Castro, and Thomas Smith Hopcraft,

ascertained in and by the following statement thereof, that is to
say :-
-
Our Invention or discovery relates to the treatment of the plant
known in Africa as the "tamarinha plant" for the production of citric
acid, tartaric acid, and alcohol. The plant is cut preferably when in a
green state, and is subjected to pressure to extract the juice or sap
6 therefrom, which is afterwards operated upon by the usual appliances or
machinery by which such acids and alcohol are generally made. The
plant may however be collected when in a full grown state, or when in
flower or in fruit (berry), and then be operated upon either by pressure
or by boiling or steaming; but the yield of acid and alcohol will not be
so large in proportion to the quantity of plant operated upon as from
that in a green state.
And having now described the nature of our said Invention or dis-
covery, and in what manner the same is to be performed, we declare
that we claim,-

page_text: We also claim the treatment of the tamarinha plant in the several
manners or by the methods herein-before described, and the production
of citric acid, tartaric acid, and alcohol therefrom or thereby.
In witness whereof, I, the said Thomas Smith Hopcraft, for myself
and on behalf of the said Antonio de Saldanha Albuquerque e
Castro and Antonio Paes de Sande e Castro, have hereunto set my
hand and seal, this Fourteenth day of January, One thousand
eight hundred and seventy-four.
