LETTERS PATENT to James Burrell, of Hammersmith, in the County
of Middlesex, Marine Engineer, for the Invention of "AN IMPROVED
COMPOSITION FOR COATING THE HULLS OR, BOTTOMS OF IRON SHIPS TO PRESERVE
THEM WHEN IN SEA OR OTHER WATER, ALSO APPLICABLE FOR THE LIKE
PRESERVATION OF ANY IRON, WOOD, OR STONE."
I, JAMES BURRELL, of Hammersmith, in the County of Middlesex,
Marine Engineer, do hereby declare the nature of tho said Invention
for "AN IMPROVED COMPOSITION FOR COATING_THE_HULLS OR BOTTOMS-OF-IRON--
SHIPS TO PRESERVE THEM WHEN IN SEA OR OTHER WATER, ALSO APPLICABLE FOR
THE LIKE PRESERVATION OF ANY IRON. WOOD, OR STONE," to be as follows:—

page_text: improved coating composition, which I propose to call the "prophylactic"
composition, for marine purposes, which will be employed to prevent
the adherence of animal or vegetable matter, also as a preservative
coating for iron exposed to sea or fresh water.
The composition is intended to prevent the adherence or growth of all 5
animal or vegetable matter, or whatever it is applied to, such as an iron
ship's bottom or hull, and also as a preservative coating for any iron,
wood, or stone.
The coating is made of two distinct compositions, the one being mixed
with any drying oil, and the other with any undrying oil; the two com- 1
positions will be used either separately or combined. If used together
the drying composition to be used first, and afterwards the undrying
composition, but in some cases it is not absolutely necessary to use any
of the drying composition, as ordinary paint can be used first, and then
the undrying composition may be put on over it.
1
The coating composed of the materials herein-after named is to be
ground or pulverized quite fine, and mixed together and thoroughly
incorporated, and it should be of the consistency of thick paint. The
several proportions however may be varied to suit the different purposes,
or some of the material may be left out altogether. The colour can also 2
be altered or varied by adding any suitable colouring matter.

TO PRESERVE THEM WHEN IN SEA OR OTHER WATER, ALSO APPLICABLE FOR THE
LIKE PRESERVATION OF ANY IRON, WOOD, OR STONE," upon the condition
(amongst others) that I, the said James Burrell, my executors or admi-
nistrators, by an instrument 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

Office within six calendar months next and immediately after the dato

.
NOW KNOW..YE, that I, the said James Burrell, do hereby declare
the nature of my said Invention, and in whạt manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement in writing, that is to say :-
This Invention relates to the manufacture and application of an
improved coating composition, which I propose to call the "prophylactio"
composition, for marine purposes, which will be employed to prevent the
adherence of animal or vegetable matter, also as a preservative coating
3 for iron exposed to sea or fresh water.
The composition is intended to prevent the adherence or growth of
all animal or vegetable matter on whatever it is applied to, such as an
iron ship's bottom or hull, and also as a preservative coating for any
iron, wood, or stone.

The coating is made of two distinct compositions, the one being mixed
with any drying oil, and the other with any undrying oil; the two
compositions will be used either separately or combined. If used
together the drying composition is to be used first, and the undrying
composition afterwards, but in some cases it is not absolutely necessary
to use any of the drying composition, as ordinary paint can be used first,
and then the undrying composition may be put on over it,

page_text: The coating composed of the materials herein-after named is to be
ground or pulverized quite fine, and its components thoroughly mixed
and incorporated, and it should be of the consistency of thick paint.
The several proportions however may be varied to suit the different
purposes, or some of the materials may be left out altogether. The 5
color can also be altered or varied by adding any suitable coloring
matter.

page_text: The chalk or lime is to be subjected before mixing to the action of
coal gas or carbonic acid gas, or the two combined. If chalk is used it
is to be perfectly dry, then broken quite fine, and enclosed in a close box
or case, and it is to be continually moved, so that all parts will be sub-
mitted to the action of the gases.
In the making of the oond on land

page_text: Either of the above compositions can be applied and used just as
ordinary paint is applied, and either with or without heat.
Another variation of the above compositions can be made as follows,
and may be used either for coating or as an antifouling composition for
ships' bottoms:—
Of Sulphur
Lime prepared or treated
by gas
Calamine (ore of zinc)
Oxido of mercury
Sugar of lead.
Oil (drying or undrying)
