Warwick, Merchant, for the Invention of "IMPROVEMENTS IN PRESERVING
ANIMAL AND VEGETABLE SUBSTANCES."
Sealed the 9th September 1876, and dated the 10th May 1876.

Office of the Commissioners of Patents on the 10th May 1876.

"IMPROVEMENTS IN PRESERVING ANIMAL AND VEGETABLE SUBSTANCES."
This Invention consists in preserving animal and vegetable substances by the
employment of the chemical element boron in combination with lime, as found in
its native or natural state and known as borate of lime. This may be applied
either solid, or in the form of powder, or in solution and alone, or in combination
with any other boron, alkaloid, or compound, or with any carbonaceous earth as
chalk, whiting, or gypsun, or with wheaten or other farina, wood charcoal,
glycerine, or oil. It is useful as a preservative from decomposition of all descriptions
of foods, hides, and furs, wools, hair, and feathers, and is especially valuable in
In
keeping cut or otherwise manufactured tobaccos free from mould or mildew.
dressing articles of food or any other animal and vegetable matters one mode in
which I apply the borate of lime is by dusting or powdering the surfaces of the
substances under operation, and if any boron salt such as borate or biborate of
soda be used therewith, I prefer to mix it in equal parts; or by another process I
can use borate of lime in solution in the proportions constituting an ordinary cold
saturated solution, and apply this solution in any manner suitable to the purpose
desired.
The several other ingredients named would be employed as diluents only, and
for the purpose of increasing bulk when the proportion of boron requires to be
small.
In dressing edible substances the borate of lime is to be preferred, as it will not
impart to such substances any of the unpleasant flavour usual with other forms of
boron.

'IMPROVEMENTS IN PRESERVING ANIMAL AND VEGETABLE SUBSTANCES."
This Invention consists in preserving animal and vegetable substances by the
employment of the chemical element boron in combination with lime, as found in
its native or natural state and known as borate of lime. This may be applied
either solid, or in the form of powder, or in solution, and alone, or in combination
with any other boron compound or with any carbonaceous earth, as chalk, whiting,
or gypsum, or with wheaten or other farina, wood, charcoal, glycerine, or oil. It
is useful as a preservative from decomposition of all descriptions of human, animal,
and vegetable substances and tissues, whether for edible or for other purposes, but
more especially for hides, skins, furs, wools, hair, and feathers, and it is especially
valuable in keeping cut or otherwise manufactured tobacco free from mould, inildew,
or other decomposition. In dressing articles, animal carcases, whole or in parts,
or vegetables, fruits, or other substances, for food, one mode in which I prefer to
apply the borate of lime is by dusting or powdering the surfaces of the substances
under operation, and if any boron salt such as borate or biborate of soda be used
therewith, I prefer to mix it in the proportion of 5 to 10 parts of the borate or
biborate in each 100 parts of borate of lime. Or by another process I can use
borate of time in any solution, but the one I prefer is in the proportions con-
stituting an ordinary cold, temperate, or warm saturated solution, and I apply this
solution in any manner suitable to the purpose desired.
The several other ingredients named, such as carbonaceous earth, chalk, gypsum,
whiting, wheaten or other farina, wood charcoal, glycerine, and oil, would be
employed as diluents only, and for the purpose of increasing bulk when the pro-
portion of boron required is small.
In dressing edible substances the borate of lime alone is to be preferred, as it
will not impart to such substances any of the unpalatable flavours caused by other
compounds of boron, such as boracic acid, biborato of soda, or borax.
For dressing hides, furs, wools, hair, feathers, and other animal and vegetable
substances, and specially all kinds of native or manufactured tobaccos and other
vegetable products used for smoking and fumigation not to be used as foods I
may add 25 to 50 per centum of biborate of soda or borax to the borate of lime.
For preserving the human body from decomposition I prefer to use boron in
its purest shape, as found in the best quality of borate of line, or in anhydrous
borax, alone or mixed, and by dusting or powdering the entire surface therewith.
Having thus described the nature of the said Invention and the manner in
which the same is to be performed, I claim the several "Improvements in Pre-
serving Animal and Vegetable Substances," as herein more fully set forth and
specified.
In witness whereof, I, the said Arthur Robottom, have hereunto set my hand
and scal, this Sixth day of November, in the year of our Lord One thousand
