page_text: JULIAN, of Sorgues, France, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Fourth day of Sep-
tember, One thousand eight hundred and fifty-one, in the fifteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Dominique Julian, my exors, adñiors, and assigns, Her especial
licence, full power, sole privilege and authority, that I, the said Dominique
Julian, my exors, adiñors, or assigns, or such others as I, the said Dominique
Julian, my exors, admors, 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
"IMPROVEMENTS IN EXTRACTING THE COLORING PROPERTIES OF MADDER, AND IN
RENDERING USEFUL THE WATER EMPLOYED IN SUCH PROCESSES;" in which said
Letters Patent is contained a proviso, that I, the said Dominique Julian, shall
cause a particular description of the nature of my said Invention, and in what
manner the same is to be performed, by an instrument in writing under my
hand and seal, to be inrolled in Her Majesty's High Court of Chancery within
six calendar months next and immediately after the date of the said in part

page_text: recited Letters Patent, as in and by the same, reference being thereunto had,
will more fully and at large appear.
NOW KNOW YE, that, in compliance with the said proviso, I, the said
Dominique Julian, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, that is to say:-
I operate on madders of all qualities reduced to a powder; I take two cwt.
of madder; I put them in a box, in which I put immediately afterwards the
quantity of one hundred and thirteen to one hundred and eighteen gallons of
water, according to the fineness of the powder; I dilute the madder with the
water, in order that every particle of madder may be well impregnated with
water. Immediately after this operation I allow the liquid madder to run
through a woollen cloth, placed upon a cross frame, fitting in the tun into
which the liquid is run to be filtered. The tun is provided with a cock for
the exit of the water. The said filter is to contain not less than six English
cwt., so that, by repeating the operation first described three times, the filter
will be filled. The cock of the tun is then opened, and by pipes the water
which has passed through the filter is conveyed to large wodden tuns. When
the water is quite drawn off, I take the madder, which is now a wet paste, out
of the filter, and I put it in linen bags or baskets, and press the whole with a
hydraulic press, in order to extract again as much water as I can. This water
is added to that before drawn off.
When the paste is well pressed, I place it in stoves heated by a common
process, from one hundred and twenty to one hundred and sixty degrees of
Fahrenheit. When the paste is perfectly dry, I reduce it in powder, I put it
through a seive, and I mix the whole with care, in order to have all the parts
similar to each other. To this product I give the name of flowers of madder.
A given quantity of this product employed for dyeing will go much farther
than a like quantity by weight of madder, from which it has been extracted;
and giving besides to the calico printers the Turkey red, and to the wool dyers
a considerable saving in work. In order to render useful the water employed
in the process, all the water flowing out of the filters and of the hydraulic
presses is conveyed in large tuns of two thousand five hundred to three
thousand gallons. These tuns are to be placed in a rooni, heated to a tem-
perature of seventy to eighty-five degrees of Fahrenheit. The water is to be
kept in these tuns till the alcoholic fermentation is produced, that is to say,
about five or six days. If, after that time, the alcoholic fermentation is not
produced, I put in the tuns five gallons of boiling water, in which I have
dissolved ten or twelve pounds of barm. I mix the whole in the tun, and wait
