MENT IN THE METHOD OF APPLYING ARTIFICIAL TEETH" to be as follows:-

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HAINES WHITE, of Manchester, in the County of Lancaster, Dentist, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing late the Twenty-fourth day of February, in the year of our
Lord One thousand eight hundred and fifty-five, in the cighteenth year of
Her reign, did, or Herself, Her heirs and successors, give and grant unto
me, the said John Haines White, Her especial license that I, the said John
Haines White, my executors, administrators, and assigns, or such others as
I, the said John Haines White, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at all
times thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for "AN
IMPROVEMENT IN THE METHOD OF APPLYING ARTIFICIAL TEETH," upon the con-
dition, amongst others, that I, the said John Haines White, by an instrument
in writing under my hand and seal, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Scal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said John Haines White, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement (that is to say) :-
My improvement relates to such artificial teeth as are affixed to a palate,
and applied without the aid of springs, and consists in producing a rough-
ened surface thereon, constituting a number of small projecting points or
burs, for the purpose of gaining adhesion to the skin. This effect may be
attained by a variety of ordinary tools, but a method I adopt is to use an
instrument known to dentists as a sculpel, this being applied to the interior
surface of the palate, pressed thereon, and caused to turn first in one direction
and then in the other, will move along the surface and raise a series of pro-

page_text: jecting parts in a "Vandyke" form. I then operate in the same manner at
an angle to the former course, by which means the lines then produced arc
crossed, and the required effect attained; the general appearance of the
surface is that usually termed frosted, but the resemblance thereto will of
course vary accordingly as the raising is finer or coarser. The roughening
may extend over the entire surface, or over a portion thereof only, and an
indentation, such as is now used in "vacuum palates," may be combined
therewith.
Having thus described the nature of my said Invention, and the manner in
which the same is to be performed, I desire it to be understood that I am
aware of palates having been engraved on the inside thereof with various
devices, but such engraving has been of a different character to that above
described.
And I claim, as secured to me under the above in part recited Letters Patent,
producing a roughened or burred surface upon palates or upon a portion
thereof, for the purpose above set forth.
In witness whereof, I, the said John Haines White, have hereunto set
my hand and seal, this Twenty-second day of August, in the year
of our Lord One thousand eight hundred and fifty-five.
TOUN TLAINES WI
JOHN HAINES WHITE. (..)
