COMPLETE SPECIFICATION filed by the said John Henry Johnson
at the Office of the Commissioners of Patents, with his Petition and
Declaration, on the 13th April 1869, pursuant to the 9th Section
of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HENRY JOHNSON, of 47, Lincoln's Inn Fields, in the County of Middlesex,
Gentleman, send greeting.
WHEREAS I am in possession of an Invention for "A DENTAL WASH,"
and have petitioned Her Majesty to grant unto me, my executors,
administrators, and assigns, Her Royal Letters Patent for the same,
and have made solemn Declaration that the same is a communication

page_text: to me from abroad by Charles Lamoureux and Charles Alexandre Hubert
Chouet, of Paris, in the Empire of France.
NOW KNOW YE, that I, the said John Henry Johnson, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention, and
in what manner the same is to be performed, in and by the following
statement, that is to say :-
This Invention consists of a dental wash, composed of the following
ingredients in the proportions herein mentioned, that is to say :-
Essential oil of badiane or star aniseed by measure,
Ditto
French peppermint
Ditto
English peppermint
Ditto
of roses
Ditto of cloves
Alcohol of 40 degrees of strength
Ditto 53

The essential oils are to be mixed together, and the said mixture is
then to be added to the proportion of alcohol above mentioned. The
desired tint may be imparted to the mixture by the aid of cochineal, and
the whole is to be filtered, after which it will be ready for use. Many of
the essential oils herein-before mentioned may be replaced by equivalents,
such, for example, as the essential oil of aniseed for the essential oil of
badiane or star aniseed, and the essential oil of geranium for the pure
essential oil of roses.
It may be here observed that the composition herein-before described
constitutes the new wash in its pure state, and that the substitutions
above referred to are indicated for the reason that a large quantity of the
essential oils of aniseed and of roses of commerce contain in notable pro-
portions the equivalents mentioned, the use of which as and for
the purpose referred to the Inventors consider as part of their said
Invention.
The proportions herein-before mentioned have been found to give the
best results, but the Inventors do not confine or restrict themselves to
those precise proportions as they may be varied slightly according to the
richness or purity of the ingredients employed.
Having now described and particularly ascertained the nature of the
said Invention, and the manner in which the same is or may be used or

page_text: carried into effect, I would observe in conclusion that what I consider
to be novel and original and therefore claim as the Invention is,-
First. The manufacture of a dental wash composed of the herein-
before described essential oils mixed with alcohol, substantially in the
proportions and of the strength herein specified.
Second. The dispensing with all liquids other than alcohol, essential
oils, and coloring matter in the manufacture of a dental wash, as herein-
before described.
In witness whereof, I, the said John Henry Johnson, have to this
my Specification set my hand and seal, this Thirteenth day of
April One thousand eight hundred and sixty-nine.
J. HENRY JOHNSON. (L.S.)
