shall and lawfully may have and enjoy the whole profit, benefit, commodity,

reason of my said Invention, for and during the term of years therein men-
tioned; to have, hold, exercise, and enjoy the full licence, powers, priviledges,
and advantages therein granted or mentioned to be granted unto me, the
said Thomas Smyth, my exors, adiñors, and assigns, for and during and unto
the full end and term of fourteen years from the date of the said Letters
Patent next and immediately ensuing and fully to be complete and ended,
according to the Statute in such case made and provided; in which Letters
Patent there is contained a proviso, obliging mc, the said Thomas Smyth,
particularly to describe and ascertain the nature of my said Invention, and
in what manner the same is to be performed, by an instruments in writing
under my hand and seal, and to cause the same to be inrolled in His said
Majestic's High Court of Chancery within one calendar month next and
immediately after the date of the said recited Letters Patent, as in and by
the same Letters Patent, relation being thereto had, will more fully and at
large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Thomas Smyth, do hereby declare, that the nature of my said Invention, and
the manner in which the same is to be performed, are as follows, that is to
say:
The logwood or other vegetable substance is to be chipped or scraped or
cut into small pieces or shavings, and to be boiled in soft water till the water
is thoroughly impregnated with color extracted therefrom, and becomes of a
very dark color; the water so colored is then to be drawn off into some other
vessel, and the logwood or other vegetable substance is to be again boiled in a
fresh quantity of water, till the same is in like manner as the former impreg-
nated with color, when it is to be drawn off as before; and the like process
may be repeated till no more color can be extracted from the logwood or other
vegetable substance: the water impregnated with the color, and drawn off as
aforesaid, is then to be boiled until it becomes by evaporation of the consist-
ence of paste; and in boiling, the same, care-should-be taken, by-stirring the
same, or otherwise, to prevent its being burnt or scorched. The process is
then to be taken out of the cauldron, boiler, pot, or utensil in which it shall
be so boiled, and be put into casks or other utensils, in order to cool, and
as it cools it will become hard and form cakes; these cakes may be
reduced to a powder by grinding, pounding, or scraping the same, and the

page_text: akes or powder so made as aforesaid may be used for the purposes of dying
r painting.
In witness whereof, I, the said Thomas Smyth, have hereunto set my
hand and seal, this Thirty-first day of July, in the fortieth year of the
reign of our Sovereign Lord George the Third, by the grace of God
of Great Britain, France, and Ireland King, Defender of the Faith,
and so forth, and in the year of our Lord One thousand eight
hundred.
Inrolled the Thirty-first day of July, in the year of our Lord One
thousand eight hundred.
