TO ALL TO WHOM THESE PRESENTS SHALL COME, I, LOUIS

greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of March, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Louis Alexandre Laniel, Her special licence that I, the said Louis
Alexandre Laniel, my executors, administrators, and assigns, or such others
as I, the said Louis Alexandre Laniel, my executors, administrators, and
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 DRESSING OF VEGETABLE FIBROUS MATTERS APPLICABLE
IN CERTAIN SPINNING PROCESSES," upon the condition (amongst others) that I,
the said Louis Alexandre Laniel, 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Louis Alexandre Laniel, 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, that is to say:―
This improvement consists in the addition of glycerine to the water employed
in the "wet spinning" of flax, hemp, and other vegetable fibrous matters. To
this end, the glycerine is mixed with the hot or cold water of the basins in a
proportion which, according to the nature of the raw material aud the number
of the yarn, may range from one-eigth per cent. to ten per cent. by weight of
the water employed.
The above mixture may, when so desired, be rendered more antiseptic by

page_text: the addition of a small proportion of phenic acid, say, from two to ten grains
per pound weight.
Having now described the nature of the said Invention, and the manner of
carrying it into effect, I declare that what I claim is, the application to the
hot or cold water employed in wet spinning processes of a proportion of
glycerine varying from one-eighth to ten per cent., according to the nature of
the raw material and the number of the yarn to be produced.
In witness whereof, I, the said Louis Alexandre Laniel, have hereto
set my hand and seal, this Twenty-sixth day of August, in the year
of our Lord One thousand eight hundred and sixty-four.
