Marconi applied for patents for wire
less telegraph instruments on Decem-
Der Z, 1895, and received his patent
July l3, 1897, claiming it was his dis
covery and invention On April 1,
1901, nearly four years later Mar.
com applied for a reissue Of this pat.
ent and swore to the following:
THAT deponent (Marconi) verify be-
lieves that the letters patent No. $780,
los, referred to, and herewith sur
rendered, are IMPERATIVE or in
valid, for the reason that the specifi-
cation thereof is defective, and that
such defect consists particularly in the
Datentee (Marconi) CLAIMING AS
HIS INVENTION OR Dis VERY.
MORE than he had a right to claim as
new. and particularly that some of the
claims Of said letters patent No. $780,
1893, were made to cover, by their
terms, apparatus refereed to in GER
tain descriptions of apparatus employed
by one, Professor Popoff, and contain
ed in a publication, entitled, Journal
Of Russian Physico Chemical Society,
Volume 2S 1886, and the errors which
render said patent so imperative or
invalid, arose from inadvertance or
accident or mistake and without any
fraudulent or deceptive intention on
the part Of the deponent (Marconi) !"
For the benefit OF the public, we
would state that aside from Professor
Dolbear, the American inventor, who
received the first patent in the United
States for electrical communication
without wires, October 5, 1886, using
an induction coil with ground and
aerial capacities without which no
electrical communication can be sent.
Professor A. S. Popoff, Of the Torpedo
School for officers in Russia, was the
first person in the world that built
modern wireless telegraph instrument
with a cOherer, induction coil, tapped,
relay sounder orlape and ground wires;
he exhibited it publicly and worked the
same on April 25, 1895, and published
an account of IL In the above stated
journal, which was translated and pub
lished in other European journals
and papers. In these papers the con-
structionof the Popoff instruemnt, with
Illustrations of the same. were printed,
so thatanyperson Of ordinary electrical
knowledge could build and operate the
same as Professor Popoff operated
his. Eighteen months after Professor
Popoff gave his public demonstration
showing his wonderful invention. Mar
conf, then a student in London applied
for a patent for apparatus on identical
lines the same as Professor Popoff pub
licly demonstrated The public can
judge for themselves to whom the hon
or Of this wonderful invention is due
and to whom it legitimately belongs.

GENTLEMEN: During the progress Of
the recent international yacht races, the
Bulletin received dispatches from the
American Wireless Telegraph Company
They reached this Office so expeditions
ly that window bulletins were shown
on the street with greater promptness
than ever before in the long history
of the cup races. The wireless dis.
patches proved of considerable value
in reports Of the contest issued in our
numerous editions
