SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Baldwin Fulford Weatherdon in the Great Seal

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BALDWIN
FULFORD WEATHERDON, of 77, Chancery Lane, in the County of Mid-
dlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent bearing date the Twelfth day of January, in the
year of
our Lord One thousand eight hundred and seventy-five, in the thirty.
eighth year of Her reign, did, for Herself, Her heirs and successors, 1
give and grant unto me, the said Baldwin Fulford Weatherdon, Her
special license that I, the said Baldwin Fulford Weatherdon, my exc-
cutors, administrators, and assigns, or such others as I, the said Baldwin
Fulford Weatherdon, 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 DISINFECTING FLUID," a communication from
William Vigné, ainé, of Agen, Department Lot et Garonne, in the Re- 2
public of France, upon the condition (amongst others) that I, the said
Baldwin Fulford Weatherdon, my executors or administrators, 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 performed, and 3
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 Letters
Patent.

page_text: NOW KNOW YE, that I, the said Baldwin Fulford Weatherdon, 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 thereof, that is to say :-
My Invention has for its object a liquid composition to be employed
as a powerful disinfectant for neutralizing noxious effluvia or offensive
odours, whereby a more effectual and instantaneous deoderizing chemical
action is obtained, suitable for antiseptic or similar purposes, and consists
in employing for the said composition sulphate of zinc, to which is added
O sulphate and acctate of copper, phenic acid, and crystals and essence of
baryta in variable proportions, according to the strength required, the
greater or less intensity of the offensive odours to be counteracted, and
the nature; cause, or extent of the area of the infection.
=
In forming the above disinfecting fluid cach of the substances aforesaid
5 are separately dissolved in the necessary quantity of water in any con-
venient manner. The different aqueous solutions are then finally mixed
together, and subsequently employed for the above object as in practico
may be found necessary.
In conclusion to the foregoing description it may be here necessary to
) note that numerous disinfectants have hitherto been in use, but not with
the same practical results obtained by the improved composition, it
being infallible, and instantaneous in its effect, and capable of being
employed with greater advantage and at less cost than those at present
in use.
Having now fully described and ascertained the nature of the said
Invention, and the manner in which the same is to be performed and
carried into effect, I would have it clearly understood that I do not by
any means intend to confine myself to the precise details herein-before
set forth and describod, as the same may be otherwise varied without
departing from the general principle of the said Invention, nor do I
claim as new and of the said Invention the exclusive use of the several
combinations and processes herein-before described and set forth, except
when the same are employed in and for the purposes of the said In-
vention, which I hereby declaro to consist in the combination of the
•

page_text: several ingredients and mode of employing the same, in the manner and
for the purposes herein-before set forth and described.
In witness whereof, I, tho said Baldwin Fulford Weatherdon, have
hereunto set my hand and seal, this Ninth day of July, in
the year of our Lord One thousand eight hundred and seventy- 5
fivc.
