page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, greeting.
WHEREAS His most Sacred Majestie George, by the grace of God King
of Great Britain, &c., by His Letters Patents vnder the Great Seale of Great
Brittaine, bearing date at Westminster, the First day of August, in the fourth
yeare of his reigne, in consideračon of the great expence and pains which George
Campbell, of Edinburg, Merchant, hath been att in finding out "A NEW IMPROVE-
MENT OF SALT, WHICH BY A SEPERATE PREPARACON OF THE SEA LIQUOR, OR OTHER
PITT OR SALT BRINE, CONSIDERABLY AUGMENTS ITS QUANTITY, AND BY REMOVING THE
BITTER OR CORROSIVE NATURE OF THE SALT BETTERS ITS QUALITY MORE THEN BY ANY
OTHER WAY OR METHOD HITHERTO USED IN ANY OF HIS MAJESTIE'S DOMINIONS," hath
given and granted to the said George Campbell, his executors, administrators,
& assignes, the sole use and benefitt of the said improvement and Invenčon
within England, Wales, and Towne of Berwick-vpon-Tweed, for the terme of
fourteen years, according to the Statute in such cases made and provided:
And whereas, by a clause in the said Letters Patents, the said George
Campbell did propose to ascertain by writing vnder his hand and seale, to be
inrolled in the High Court of Chancery within four kallender months from the
date of the said Letters Patents, the manner and materials of his said Inven-
tion and improvement, as by the said recited Letters Patents, relation being
thereunto had, more att large appeares.
NOW BE IT KNOWN, that according to the directions of the said Letters
Patents, I, the said George Campbell, doe hereby declare that the proces of
making salt is to be in two different vessells soe placed and erected as to have

page_text: communication one with the other, but in noe event to interfero or hinder ono
the other. In one pann or vessell the sea liquor is boiled vp with a violent
strong fire, till about about nine parts of ten of the liquor or sea water is
evaporated, by which time itt comes a salt, and thereafter is conveyed to
another pann or panns, wherein the salt is perfectly made by a govern'd fire;
and all this is soe easie that by one example itt will be rendred intelligable to
the meanest capacity, or rather will discover itselfe, how soon any work is sett
agoing according to this modell. That by a curious standard which I have
discovered, and has been the means of my perceiving the errors of others, and
the advantage of the herein-recited method of making salt, I find when the
bittern predomines, then draws itt of and removes it.
In wittnesse whereof, I have hereunto sett my hand and seale, this Twenty-
first day of November, in the fourth yeare of His said Majestie's reigne,
and in the yeare. of our Lord One thousand seven hundred and seven-
