TO ALL TO WHOM THESE PRESENTS SHALL COME, I, the said
FRANCIS BERNARD BEKAERT, of Rue Royale Exterieure, Brussells, in the
Kingdom of Belgium, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent under the Great Seal of Great Britain, bearing date at Westminster,
the Twenty-ninth day of May, in the tenth year of Her reign, did give and
grant unto me, the said Francis Bernard Bekaert, my exors, admors, and
assigns, Her especial full power, sole privilege and authority, that I, the
said Francis Bernard Bekaert, my exors, admors, and assigns, and such
others as I, the said Francis Bernard Bekaert, my exors, admors, and assigns,
should at any time agree with, and no others, from time to time and at all times
hereafter during the term of years therein mentioned, should and lawfully.
might make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, my Invention of "A METHOD OF INCREASING THE QUANTITY
OF CREAM PROCURED FROM MILK, AND PRESERVING MILK;" in which said Letters
Patent there is contained a proviso that I, the said Francis Bernard Bekaert,
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 enrolled in Her said Majesty's High Court within six
calendar months next and immediately after the date of the said in part recited
Letters Patent, reference being thereunto had, will more fully and at large
appear.

NOW KNOW YE, that in compliance with the said proviso, I, tho said
Francis Bernard Bekaert, do hereby declare the nature of my Invention, and
the manner in which the same is to be performed, are particularly described and
ascertained in and by the following statement thereof, that is to say:-
My Invention consists, as regards the first part of it, namely, the method
of increasing the quantity of cream procured from milk, in the manufacture
of a liquid, which liquid, when made, I apply in the following manner :-To
two quarts of new milk I take one good table spoonful of my liquid, which I
put into the milk, when in the pan or other vessel. I then stir the milk round
once or twice; it is then left in the pan, or other vessel, and the skimming
can take place at the same time it takes place in the ordinary manner where
my liquid is not used; but I prefer the skimming to be delayed a little beyond
the usual time commonly adopted. By the application of this liquid I procure
a much larger quantity of cream to be forced to the surface of the milk than
is forced to the surface naturally when my liquid is not used. To make my
liquid I use the following ingredients and quantities:-To one quart of water
I put one ounce of carbonate of soda, one tea-spoonful of a solution of tur-
meric or curcuma, and three drops of marigold water; and as a means more
simple, and in order to avoid the necessity in making large quantities of my
liquid of weighing out the proportion of soda to the quantity of water, I find
that the same purpose is answered by putting such a quantity of soda to the
water as will, when dissolved, upon the application of a salometer, which I use
for the purpose, 'and which in Belgium is known by the denomination of a
"pése sel," show a density equal to ten degrees on the graduated scale of such
meter. I prepare my soda and water first, and I then introduce in the pro-
portions above mentioned the solution of turmeric or curcuma, and the
marigold water. I claim as my Invention to this part of my Patent, any salt
of soda when mixed with water, as before stated, and applied to milk, for the
purpose of procuring a larger quantity of cream to rise to the surface of milk
than is procured by the ordinary process now in use. The soda and the water,
made as before stated, form the basis of my Invention; the solution of tur-
meric or curcuma and the marigold water being only used by me as additions
or improvements to improve the colour and quality of the butter made from
the cream rising from the milk to which my Invention is applied,.but not being
essentially necessary for the increase of the cream. Although I find the use
of soda most convenient, I claim any other alkali, when applied in a similar
manner, or for the purposes of my Patent, as part and parcel of my Invention.
As regards the second part of my Invention, namely, a method of "pre-
serving milk," I take one table-spoonfull of my soda and water, made in the

page_text: proportion of one ounce of soda to a quart of water. I put this table-spoonfull
into an ordinary quart bottle filled with new milk, leaving only space for the
spoonfull of this liquid. I then cork up the bottle, merely putting a piece of
string round the cork to prevent its flying. I then put my bottles, thus filled
and corked, into a vessel or copper of cold water. I then bring this vessel or
copper gradually up to ebullition. I then, in the case of its being a copper
within which these bottles are boiled, withdraw the fire, and let the bottles and
the water cool together. In the case of any other vessel, I remove the same
from the fire, until the bottles and water in which they are boiled get cool
together. I claim to this second part of my Patent, the method of applying
my liquid of soda and water in the proportions above mentioned, and the
putting same into the milk, and of boiling and cooling same, in the manner
before also described, as my Invention, when applied to milk, for the purpose
of preserving same; but I do not confine myself to the nature or size of the
bottles or other vessels, having mentioned the quart bottle for the purpose
more easily of giving a proper description. The bottles, thus corked and boiled,
when cool, are put on one side for use. Neither do I confine myself to the
exact proportions of the ingredients above stated, for either process; but I
find, with the proportions as stated above, I have accomplished the object of my
Inventions. I claim also, for the second part of my Invention, any other alkali
than salt of soda, when used in a similar manner for the preservation of milk.
In witness whereof, I, the said Francis Bernard Bekaert, have hereunto
set my hand and seal, this Twenty-sixth day of November, One thousand
eight hundred and forty-seven.
