PROVISIONAL SPECIFICATION.
Improvements in and relating to Disinfectants, Blight Preventives,
and Moth and Insect Exterminators.
I JOHN BATHURST DEWHURST of 336, Mile End Road London, in the County
of Middlesex Manufacturer do hereby declare the nature of this invention to be as
follows:-
This invention consists of a composition of napthaline, camphor flowers, and
eucalyptus oil.
In the preparation of the said composition, I use the ingredients aforesaid in the
proportions substantialy as follows. To 40 ounces of napthaline I add 1. ounce of
camphor flowers, and 14 ounces of eucalyptus oil.
I first disolve the napthaline by heat, after which I add the camphor flowers and
eucalyptus oil, stirring the whole together until thoroughly incorporated.
All the ingredients aforementioned are of a highly sanitary nature and exeed-
ingly volatile, and being greatly affected by temperature, the proportions mentioned
may be somewhat varied to suit the requirements of season or climate.
This invention differs from other solid disinfectants insomuch as it contains no
water, caustic soda, or soap, these ingredients being objectionable as they reduce
the value of a solid disinfectant, and also prevent that solidity, sightliness, and
durability desired besides interfering with the natural free volatile sanitary
properties of the three ingredients mentioned as composing this invention.
Dated this 15th day of March 1892.

and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention consists of a composition of napthaline, camphor flowers, and
eucalyptus oil.
In the preparation of the said composition, I use the ingredients aforesaid, in
the proportions substantialy as follows.
To forty ounces of napthaline I add one ounce of camphor flowers, and one and
a half ounce of eucalyptus oil. I first disolve the naphaline by heat, after which 1
add the camphor flowers, and eucalyptus oil, stirring the whole togeather until
thoroughly incorporated. The resulting composition, while in a melted state is
poured into moulds so as to form tablets, blocks, rolls, or other forms of the desired
size, and for the more effective use of these tablets, blocks, rolls, or other forms,
they may be affixed to wires, or other suitable appliances so as to admit of their
being hung on walls of apartments, or other desirable places.
All the ingredients afore mentioned, are of a highly sanitary nature, and exceed-
ingly volatile, and being greatly affected by temperature, the proportions mentioned,
may be somewhat varied to suit the requirements of season or climate.
This invention differs from other solid disinfectants insomuch as it contains no
water, costic soda, or soap, these ingredients being objectionable as they reduce
the value of a solid disinfectant, and also prevent that solidity, sightliness, and

page_text: durability desired, besides interfering with the natural free volatile sanitary
properties of the three ingredients mentioned as composing this invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is,
A solid disinfectant, a blight preventive, and a moth, and insect exterminator,

substantialy as set forth.
