from abroad by Adolphe Guibert, of Paris, France.
Sealed the 1st August 1865, and dated the 4th February 1865.
PROVISIONAL SPECIFICATION left by the said Richard Archibald
Brooman at the Office of the Commissioners of Patents, with his
Petition, on the 4th February 1865.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention
for "AN IMPROVED VARNISH POR PRESERVING WOOD AND FOR PROTECTING IRON
SHIPS AND OTHER METAL-WORK FROM OXYDATION AND FROM FOULING," to be as
follows:-
-
This varnish is intended to protect wood from worms when placed in the
ground, and from marine plants and shell fish in water; it also preserves
metals from oxydation, and iron ships and structures from fouling under
water.
The Invention consists in compounding this protecting varnish of the
ingredients and in or about the proportions following:-Mix 25 parts by.
weight of galipot, 25 parts by weight of common resin, and 50 parts by weight
of essence of turpentine. To 80 parts of this mixture add 18.parts of sulphate

page_text: of copper reduced to an impalpable powder, and two parts of regulus of
antimony, also in the state of impalpable powder.
Method of preparing the varnish.-Dissolve the galipot and the resin in a
pan or other vessel, and stir the mixture, withdraw the liquid mixture, pour in
the essence of turpentine, and stir the whole; pour this mixture into another
vessel, introduce the sulphate of copper and the regulus of antimony, and stir
the mass. The varnish is poured into jars, bottles, or other receptacles, and
is ready for use. Sometimes I substitute for the turpentine petroleum,
benzine, and other mineral and vegetable oils.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman in the Great Seal Patent
Office on the 4th August 1865.
