page_text: nature of our said Invention, and in what manner the same is to be per-
formed, by an instrument in writing under our hands and seals, or under
the hand and seal of one of us, to be inrolled in. Her Majesty's High Court
of Chancery within six calendar months next. and immediately after the
date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto bad, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, we, the said
Adam Yule and John Chanter, do hereby declare that the nature of our said
Invention, and the manner in which the same is to be performed, are fully
described and ascertained in and by the following statement thereof, that is to
say:
Our Invention consists in preparing and manufacturing compositions or
paints for preserving and protecting ships or other vessels from marine deposits
on yellow metal, copper, and single-bottomed wood ships or iron, and in order
that our Invention may be more fully understood and readily carried into effect,
we will proceed to describe the means pursued by us.
First, take from eight to ten parts of bullock's gall, to which add about
thirty lbs. of carbonate of iron or plumbago in a fine powder; mix together to
form a paste; to which add four gallons of sea water, or sufficient to bring the
whole into the consistency of a paint.
Second mode, take thirty. lbs. of carbonate of iron or plumbago, finely
powdered, to about three lbs. of white arsenic, two and a half gallons of
coal tar naptha, or spirit of turpentine,, twelve to fourteen lbs. of Stockholm
pitch, dissolved in the above spirit, after which mix all well together to a
consistency of paint.
Third mode, for iron or zinc we use as a first coating a preparation of gutta
percha or india rubber, together or separately, dissolved in coal tar naptha, or
other, solvent, to such a consistency as may be readily applied with a paint
brush.
.
Fourth mode, take 10 lbs. of carbonate of iron or plumbago, finely powdered,
and one lb. of white arsenic mixed intimately, and add, with the assist-
ance of heat, as much Russian or other tallow as will serve, to incorporate
them thoroughly. This is to be applied when hot, and well rubbed with the
powder, unmixed, till dry.
In witness whereof, I,. the said John Chanter, have hereunto set my
hand and seal, this Nineteenth day of January, in the year of our
Lord One thousand eight hundred and fifty
I.
