TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDRE
MANBRE, of N. 10, Rathbone Place, Oxford Street, London, in the County of

WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Tenth day of April, in the year of our Lord One
thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,

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 "THE MANUFACTURE OF A COLOURING MATTER FOR COLOURING SPIRITS, BEVE-
RAGES, AND OTHER LIQUIDS FROM THE SUGAR OF POTATOES KNOWN AS GLUCOSE AND
SYRUP DE FECULE," " upon the condition (amongst others) that I, the said
Alexandre Manbré, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should par-
ticularly 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Alexandre Manbré, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
That this colouring is obtained from potatoe sugar called glucose or syrup
"de fecule."
This colouring is made in two different ways, and for several purposes;
first, for the colouring of vinegars, wines, spirits, beers, until proof, and any
other beverages and liquids; second, for the colouring of spirits above proof.
The first is obtained by putting in a vessel of any suitable kind and capacity,
capable of being heated from a naked fire, or otherwise, the quantity of glucose
wanted, when the glucose is heated up, just before the beginning of the ebul-

page_text: lition, all the floating part containing the froth and other impurities should be
taken out. It must be burnt until it has lost all its sweetness or flavour of
sugar. Then add the quantity of water required by pouring it all round the
vessel, but not in the middle, to avoid any explosion, and boil it afterwards, as
usual. If the colouring is wanted to be solid, it should be taken out of the
vessel before adding any water. If, instead of taking out the froth as above
stated, one pound of alum or soda for every hundredweight of glucose be
added, together with the water, the colouring will be of a superior quality.
The second is obtained in proceeding as the first, the only difference con-
sists in putting into the vessel together with the glucose two pounds of potash
for every hundredweight of glucose, and also two pounds of alum or soda to
be put in at the same time with the water.
