WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters

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, the said Constantine Nicolaus Kottula, Her special licence that I, the
said Constantine Nicolaus Kottula, my executors, administrators, and assigns,
or such others as I, the said Constantine Nicolaus Kottula, my executors,
administrators, or assigns, should at any time agree with, and no others, from
time to time and at all 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 "AN IMPROVEMENT IN THE MANUFACTURE OF NEUTRAL
HAND OR SKIN SOAP," upon the condition (amongst others) that I, the said
Constantine Nicolaus Kottula, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals, should
particularly 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
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Constantine Nicolaus Kottula, do
hereby declare the nature of my said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement thereof (that is to say):-
My said Invention consists in mixing fatty matters with certain quantities
of highly concentrated soda leys, which I purify with a certain quantity of
alum and salammoniac for the purpose of producing better and cheaper
neutral hand or skin soap than by any means. heretofore adopted. And
the manner in which I carry my Invention into practical effect is as
follows: I prepare the highly concentrated leys by boiling until they reach,
say, about 30 to 33 degrees Beaumé, add about 5 lbs. of alum to each cwt.
of leys, and boil both together about half an hour. I remove the leys and
alum from the heat, and add to each cwt. of leys 1 lb. of salammoniac, stir

page_text: half an hour, cover, and allow the mass to settle and become perfectly clear.
To obtain the leys stronger than 33 degrees, I make a second addition of
alum, but in smaller proportion. To obtain leys of 42 degrees, I make a third
addition of alum, and then add the salammoniac. I melt a quantity of any
fatty matter used in soap making, and while still hot stir and add the bighly
concentrated purified leys prepared as above described, say, to every 100 lbs. of
fatty matter about 100 lbs. of the leys of 30 degrees Beaumé, or about 90 lbs.
of the leys of 33 degrees Beaumé, or about 80 lbs. of the leys of 36 degrees
Beaumé, or about 70 lbs. of the leys of 39 degrees Beaumé, or about 60 lbs.
of the leys of 42 degrees Beaumé, 'continue to agitate the mass until it
commences to become thick, and when thick it can be transferred to the
frames. After the soap is finished it may be colored, mottled, or perfumed in
the manner well known to soap makers.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim the manufacture
of neutral hand or skin soap in the manner herein-before described.
In witness whereof, I, the said Constantine Nicolaus Kottula, have
hereunto set my hand and seal, this Twenty-second day of September,
One thousand eight hundred and fifty-eight.
CONST. N. KOTTULA. (L.S.)
