PROVISIONAL SPECIFICATION left by the said Matthew Tomlinson at
the Office of the Commissioners of Patents, with his Petition, on the.
21st December 1855.
I, MATTHEW TOMLINSON, of Ivy House, Culcheth, in the County of Lan-
caster, Manufacturer of Medical Plaisters, do hereby declare the nature of.
the said Invention for "AN IMPROVED MEDICAL PLAISTER" to be as follows:-
My Invention consists of a combination or amalgamation of cod liver oil
with a preparation of lead called lytharge, so as to produce a pigment or
plaister, which I call "cod liver oil plaister." I effect the said combination.
or amalgamation by boiling the same together, with or without the addition
of water or other fluid, whereby the said oil is amalgamated with the lead or
lytharge in the form of a plaister, in which form it may be used for medical
purposes, as an external application, with greater advantage than any other
form hitherto known.

TO ALL TO. WHOM THESE PRESENTS SHALL COME, I, MATTHEW
TOMLINSON, of Ivy House, Culcheth, in the County of Lancaster, Manufacturer
of Medical Plaisters, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Royal
Letters Patent, bearing date the Twenty-first day of December, in the year of
our Lord One thousand eight hundred and fifty-five, in the nineteenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Matthew Tomlinson, Her special licence that I, the said Matthew
Tomlinson, my executors, administrators, and assigns, or such others as I,
the said Matthew Tomlinson, 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
IMPROVED MEDICAL PLAISTER," upon the condition (amongst others) that I, the
said Matthew Tomlinson, by an instrument in writing under my hand and
seal, should particularly describe and ascertain the nature of the said Inven-
tion, 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 Royal Letters Patent.
NOW KNOW YE, that I, the said Matthew Tomlinson, do hereby declare
the nature of the 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) :-
My Invention consists of a combination or amalgamation of cod liver oil
with a preparation of lead called "litharge," so as to produce a pigment or
plaister which I call "cod liver oil plaister." I effect the said combination
or amalgamation by boiling the same together, with or without the addition of
water or other fluid, whereby the said oil is amalgamated with the lead or
litharge in the form of a plaister, in which form it may be used either alone
or in combination with resinous gums or other substances for medical pur-
poses, as an external application, with greater advantage than any other form
hitherto known.
Having thus described the nature and particulars of my said Invention, I
desire it to be understood that I do not confine myself to the exact pro-

page_text: portions of the materials herein-before specified, as such may be varied
according to the strength or substance of the same. But what I claim as of
my Invention, and believe to be new, to the best of my knowledge and belief,
within this realm is, the combination or amalgamation of cod liver oil (instead
of the oils formerly used) with a preparation of lead called "litharge," in
addition with any resinous substances or without them, so as to produce a
pigment or plaister for medical purposes, as herein described.
In witness whereof, I, the said Matthew Tomlinson, have hereunto set
my hand and seal, this Nineteenth day of June, One thousand eight
hundred and fifty-six.
MATTHEW TOMLINSON. (LS.)
Signed, sealed, and delivered by the within-named
Matthew Tomlinson, in the presence of
E. J. HUGHES, Patent Agent,
Manchester.
