TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ATWOOD GLASS, of 115, Leadenhall Street, in the City of London, Submarine
Telegraph Cable and Wire Rope Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of May, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-second year of
Her reign, did, for Herself, Her beirs and successors, give and grant unto
me, the said Richard Atwood Glass, Her special licence that I, the said
Richard Atwood Glass, my executors, administrators, and assigns, or such
others as I, the said Richard Atwood Glass, 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 Inven-
tion for "IMPROVEMENTS IN SUBMARINE ELECTRIC TELEGRAPH CABLES," upon the
condition (amongst others) that I, the said Richard Atwood Glass, my
executors or administrators, by an instrument in writing under my, or their,
or one of their hands and seals, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be per-
formed, and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Richard Atwood Glass, 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 thereof, that is to say:-
In the Provisional Specification of this Invention it was stated, first, that
my Invention consisted in protecting the insulated conducting wires of sub-
marine electric telegraph cables, whatever may be the material with which the
same are insulated, by surrounding the insulating material with wires of iron,

page_text: steel, or other suitable metal, which wires are individually and separately
"served" or covered with hemp or other like substance, and then laid
individually around or upon the insulating material. I have since discovered
that this part of my Invention was not new, and I therefore omit from this
Complete Specification all claim to that supposed improvement.
My Invention now consists in insulating the conducting wires of submarine
electric telegraph cables by coating or covering them first with a layer or
layers of gutta percha, and then with a layer or layers of one or more of the
compositions or compounds for which Letters Patent were granted to Leonard
Wray, on the Twelfth day of October, One thousand eight hundred and fifty-
eight, No. 2270.
In witness whereof, I, the said Richard Atwood Glass, have here-
unto set my hand and seal, this Twenty-fourth day of November, One
thousand eight hundred and fifty-nine.
R. A. GLASS. (L.S.)
