I, JAMES LAMBLE, of Southampton, in the County of Hants, Plumber
and Painter, do hereby declare the nature of my said Invention for "A
NEW OR IMPROVED COMPOSITION FOR THE COATING AND PRESERVATION OF SHIPS'

page_text: In order to make this composition I take of barytes four hundredweight
and two quarters in weight; of driers, so called or known as Patent driers,
twenty-four pounds weight; of white lead, fifty-six pounds weight; of corrosive
sublimate, twenty-eight pounds weight; of linseed oil, two and a half gallons
or twenty pounds weight; of turpentine, two and a half gallons or twenty-
pounds weight. I mix these ingredients carefully together in the way
or manner in which ordinary paint is mixed. In using this composition or
mixture I prefer first to apply a coating of red lead or white lead or a mixture
of red and white lead; and after the said coating has thoroughly dried.I apply
my new or improved mixture in the way or manner in which ordinary paint
would be applied.
For the purpose of colouring or staining this composition or mixture I
prefer to use either Venetian red or umber in the proportion of about ten
pounds weight of either ingredient to the quantities above named of the
composition.
The quantities named of the various ingredients will make six hundred-
weights of my composition. I do not confine myself strictly to the exact
amount or proportion of each ingredient, but prefer to use them in the
proportions above mentioned.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Lamble in the Great Seal Patent Office on the 11th
July 1867.

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 James Lamble, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
My Invention consists in the manufacture of a new or improved composition
for the coating and preservation of the bottoms of iron and wood ships, and in
the application of the said composition or mixture to that purpose.
In order that the nature of my Invention, and the manner in which the
same is to be performed, may be distinctly understood and ascertained, I now
state the manner in which I make and apply this composition. I take of
barytes four hundredweight and two quarters in weight; of driers, so called
or known as patent driers, twenty-four pounds weight; of white lead, fifty-six
pounds weight of corrosive sublimate, twenty-eight pounds weight; of
linseed oil, two and a half gallons, or twenty pounds weight; of turpentine,
two and a half gallons, or twenty pounds weight. I mix these ingredients
carefully together in the way or manner in which ordinary paint is mixed.
In using this composition or mixture I prefer first to apply a coating of red
lead or white lead or a mixture of red lead and white lead, and after the said
coating has thoroughly dried I apply my new or improved mixture as above
described in the way or manner in which ordinary paint would be applied.
For the purpose of colouring or staining the composition or mixture 1 prefer
to use either Venetian red or umber in the proportion of about ten pounds
weight of either ingredient to the quantities above named of the composition.
The quantities named of the various ingredients will make six hundred-
weights of my composition. I do not confine myself strictly to the exact
amount or proportion of each ingredient, but prefer to use then in or about
the proportions above mentioned.
Having now particularly described the nature of my Invention, and the
manner in which the same is to be performed, I wish it to be clearly under-
stood that what I claim is, the manufacture and use of the composition for

page_text: the coating and preservation of ships' bottoms of the ingredients in or about
the proportions in this Specification described.
In witness whereof, I, the said James Lamble, have hereunto set my
hand and seal, this Thirtieth day of May; in the year of our Lord Ono
thousand eight hundred and sixty-seven.
Witness,
G. Y. MERCER.
JAMES LAMBLE. (L.S.)
