WHEREAS Her present most Excellent Majesty Queen Victoria, by Her

Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Charles Low, my exors, adiñiors, and assigns, Her especial licence,
full power, sole privilege and authority, that I, the said Charles Low, my
exors, admors, and assigns, and such others as I, the said Charles Low, my
exors, adiñors, or assigns, should at any time agree with, and no others, from
time to time and at all times during the term of years therein expressed,

Wales, and the Town of Berwick-upon-Tweed, in the Islands of Guernsey,
Jersey, Alderney, Sark, and Man, and also in all Eler said Majesty's Colonies
and Plantations abroad, my Invention of "IMPROVEMENTS IN SMELTING COPPER
ORE;" in which said Letters Patent is contained a proviso, that I, the said
Charles Low, should cause a particular description of the nature of my said
Invention, and in what manner the same is to be performed, by an instrument
in writing under my hand and seal, to be inrolled in Her said 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 had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I the said
Charles Low do hereby declare that the nature of my said Invention, and the
manner in which the same is to be performed, are fully described and ascer-
tained in and by the following statement thereof, that is to say :-
My Invention consists of the introduction of atmospheric air into the fur-
naces used for the manufacture of copper, in such manner that currents of air
'may be introduced above the melted metal and yet below the flame and
heated products at the upper part of the furnace.
In ordinary furnaces now in use openings are left in the top of the furnace
for occasionally admitting air, and also others for charging the furnace; now,
my Invention consists of constructing furnaces used for such purposes with
apertures so situated as to allow currents of air to pass over the surface of the
melted metal and under the flame or heated air which is at the upper part of
the furnace, which currents of air, so introduced above the metal and yet below
the flame, becoming decomposed and parting with its oxygen assists the
separation of the metal from its ores; for this purpose I construct the furnaces,
when of the reverberatory kind, with several apertures or orifices in the
bridge, and at other parts of the furnace near the bridge, but openings in the
sides of the furnace may, where convenient, be made for this purpose, which
apertures allow currents of air to pass into the furnace to effect the above
object.
In witness whereof, I, the said Charles Low, have hereunto set my
hand and seal, this Twenty-third day of June, in the year of our
Lord One thousand eight hundred and forty-nine
CHARLES (L.S.) LOW.
AND BE IT REMEMBERED, that on the Twenty-third day of June, in
the year of our Lord 1849, the aforesaid Charles Low came before our said
Lady the Queen in Her Chancery, and acknowledged the Specification afore-
said, and all and every thing therein contained and specified, in form above
written. And also the Specification aforesaid was stamped according to the
tenor of the Statute made for that purpose.
Enrolled the Twenty-eighth day of June, in the year of our Lord One
thousand eight bundred and forty-nine.
