NEWTON, of Chancery Lane,in the County of Middlesex, Civil Engineer, send
greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Eleventh day of March, in the fifth year of His reign,
and in the year of our Lord One thousand eight hundred and thirty-five, did
give and grant unto me, the said William Newton, my executors,administrators,
and assigns, His especial license, full power, sole privilege and authority, that I,
thesaid William Newton,myexecutors, administrators, and assigns.or suchothers
as I, the said William Newton, my executors, administrators, or assigns, should
at any time agree with, and no others, from time to time and at all times here-
after duringthe term of years therein expressed,should and lawfully might inake,
use, exercise, and vend, within England, Wales, and the town of Berwick-upon-
Tweed, an Invention of "A METHOD OF PREPARING ANIMAL MILK, AND BRINGING IT
INTO SUCH A STATE AS SHALL ALLOW OF ITS BEING PRESERVED FOR ANY LENGTH OF
TIME WITH ITS NUTRITIVE PROPERTIES, AND CAPABLE OF BEING TRANSPORTED TO ANY
CLIMATE FOR DOMESTIC OR MEDICINAL USES," being a communication made to
me by a certain foreigner resident abroad; in which said Letters Patent is
contained a proviso obliging me, the said William Newton, by an instrument
in writing under my hand and seal, particularly to describe and ascertain the
nature of the said Invention, and in what manner the same is to be performed,
and to cause the same to be inrolled in His Majesty's High Court of Chancery
within six calendar months next and immediately after the date of the said
in part recited Letters Patent, as in and by the same, reference being there-
unto had, will more fully and at large appear,

page_text: NOW KNOW YE, that in compliance with the said proviso, 1, the sam
William Newton, do hereby declare that the nature of the said Invention, and
the manner in which the same is to be performed,are particularly described and
ascertained in and by the following description thereof (that is to say):-
The Method of Preparing Animal Milk, and bringing it into such a State as
shall allow of its being preserved for any Length of Time with its Nutritive
Properties, and capable of being Transported to any Climate for Domestic or
Medicinal Purposes, consists in simply evaporating the aqueous parts from the
liquid milk, and leaving the other constituent parts of the milk in a concen
trated state, unaltered by any chemical change, which I effect in the following
manner - Taking the milk in a fresh state, as drawn from the animal, having
first strained it, if necessary, to get rid of any dirt or other improper matter
which may have accidentally fallen into the pail or other vessel while milking,
I introduce into the milk a small quantity of pulverised loaf sugar, say from
fiftieth to one hundreth part in weight of the whole quantity of the milk, which
quantity may however be greater,dependant upon the desired sweetness of the
preparation whencompleted. Onthesugarbecomingperfectlydissolved Isubject
the milk to a tolerably rapid evaporation, either by blowing through the milk
warm or cold air by means of a suitable apparatus of any convenient form,
such, for instance, as those at present in use for evaporating syrups, or by
means of external warmth in connexion with a vacuum above the surface,
produced in any of the ordinary ways as applied to evaporation. By whatever
process, however, the evaporation is carried on. the milk may with advantage
be subjected to a gentle warmth to quicken the operation, but that warmth
will be best obtained from hot water or from steam, or heated air, applied to the
outside of the vessel which contains the milk, as the direct action of fire upon
the vessel may tend to injure the properties of the milk, and perhaps give it
an unpleasant flavor. By evaporating the aqueous particles of the milk in
this way, its nutritive or essential parts may be concentrated, and its substance
reduced to the consistency of cream, honey, or soft paste, or even into dry
cakes or powder, and may in the latter states be exposed to the air for a length
of time without being impaired, the sugar tending to preserve it. By dissolving
the milk so prepared in a proportionate quantity of warm or cold water the
original milk is reproduced, with all its properties, original flavor, and salutary
qualities. It is desirable to dilute the concentrated milk at first in a small
portion of water, and to add afterwards the necessary quantity to bring it into
the liquid state, otherwise it would be difficult to dissolve the milk completely.
This process of preparing milk affords the means of conveying it, without
injury, to any distance, in any climate, and of retaining, by concentration, the

page_text: delicious flavor of the milk peculiar to one country, and reproducing it in
anotherwith its original qualities. When evaporated to the consistency of paste,
it may be taken as food by persons who, on account of the weakness of their
digestive organs, cannot take milk in its liquid state. It is obvious that every
kind of animal milk may be prepared in the same manner, whether it comes from
the cow, the goat, the ass, or even from the human breast. When evaporated
to the consistency of a syrup it may be put in bottles or phials; when concen-
trated to the consistence of honey, in suitable pots; when brought to that of a
thick paste it may be shaped into lozenges or dried and reduced to powder.
Milksopreparedmay, withoutlosinganyofits properties, beafterwardscombined
with any medicinal, aromatic, or nutritious substances. When reduced into
powder, milk may be advantageously mixed with cocoa, and dried into cakes,
and by diluting it with warm water will give excellent chocolate. When
brought to the consistence of honey, it may be mixed with a strong infusion
of coffee, or of tea, and being further evaporated will keep, and afterwards
yield, when dissolved with warm water, coffee or tea of the usual strength and
flavor. This improved method of preparing milk is essentially different from
all preparations of milk heretofore known, and is particularly unlike the
preparation described by Mons. Braconneau, inasmuch as milk prepared upon
his plan is decomposed, while by my process it is only concentrated, without
being chemically changed. The process of Mous". Braconneau consists in
seperating, by means of an acid, the serum from the other constituents of
milk,and adding to the residuum (viz., the caseum and the butyrous substance)
a sufficient quantity of carbonate of soda to render it soluble in liquid. The.
milk so prepared must be recomposed for use, but it never can be brought to
the perfect flavor and condition of real good milk, as many of its orginal
properties are necessarily destroyed or modified, however exact the analysis
and however great the skill of the operator; on the contrary, the milk thus
prepared by me undergoes no chemical change, but its constituent substances
are merely concentrated, by driving off or evaporating the aqueous parts, and
the milk with all its original flavor and nutritious qualities will be again
restored by the addition of simple water.
In witness whereof, I, the said William Newton, have hereunto set my
hand and seal, this day of September, in the year of our Lord One
thousand eight hundred and thirty-five.
