the audiphone wonld bardiiy identity it as
the wonderful new invention by which peo-
pie hear with their teeth. a Post reporter
saw at Mr. Fisher 5 store on Seventh street,
Saturday, the inst audpho0e that has come
10 the city. IL is made Of a composition, the
major portion of which is vuicanite. Al the
back Of Il is Il black silk cord stretching from
the upper edge OF the handle, where ii is fasien-
ed down with spring By means of this
cord the instrument is tuned like n violin,
and tension is regulated according 10 The dis

string is drawn down and fastened at the

against the two upper teeth the vibrations

by sound on the drum of the ear. or all the
inventions of modern times it is the simplest.
1t Is absolutely innocent Of mechanism. No
grinding out OF weird and ghastly words
with a crank. No holding a telephone tube

end Of the line TO say what he wants to say
and say it plainly or stop ringing that bell
Mr. Edison, who dazzles us with his brilliant
necromancy, has as Yet invented nothing so
simple as these new spectacles for the earsn
brought 10 public attention by Mr. Rhodes,
of Chicago. Himself very deaf for over TWEEN
ty years, he has for long time been expert
menting in devices for overcoming deafness,
and first had his attention turned in the di-
recioE Of the present invention by observing
that he could hear his watch tick when he
placed it between his teeth something that he
couldn't do by holding it to his ear. Per-
haps the idea is not bran new Beethoven used
as a substitute for the ear metallic rod, which
he held between the teeth, with the other end
on the sounding-board of the piano, and thus,
and thus only, was he enabled TO hear the
music that his brain had produced Mr.
Rhodes experimental When the telephone
came out he took hint from that. Like the
critic with the white owl, he has made the
audiphone his study for years He tried one
hundred kinds of wood, tried tin, silver, steel
aud sounding brass, settling down at last on
a composition of paper and vulcanized rubber.
II has been tested in a number of cases, and is
already in satisfactory use by many people.
BY applying the discs of the opera audlphone
10 his teeth, Mr.. Joseph Medill, of the Chicago
Tribune, is enabled once more TO enjoy theatre
going, and esifes that is not only is imme-
daiely servicea9le but is restoring the lost
sense OF hearing. Another enthusiastic ind-
vidual stays at home from church one morn

dphone, by which he was induced TO make II

invention would be an emancipation proca-

The National Deaf aud Dumb institute de-
fines correctly its limitations when he says
that lin the very many cases of deafness
where The auditory nerve is impaired, The
audphone can be Of no avail; but where
as is often the case, the defect is only in those
parts Of the ear by which vibrations are CON
