He
even
called
his
arrangement
a
'telephone.'
[Robert
Hooke,
in
his
MICROGRAPHIA,
published
in
1667,
writes:
'I
can
assure
the
reader
that
I
have,
by
the
help
of
a
distended
wire,
propagated
the
sound
to
a
very
considerable
distance
in
an
instant,
or
with
as
seemingly
quick
a
motion
as
that
of
light.'
Nor
was
it
essential
the
wire
should
be
straight;
it
might
be
bent
into
angles.
This
property
is
the
basis
of
the
mechanical
or
lover's
telephone,
said
to
have
been
known
to
the
Chinese
many
centuries
ago.
Hooke
also
considered
the
possibility
of
finding
a
way
to
quicken
our
powers
of
hearing.]
A
writer
in
the
REPOSITORY
OF
ARTS
for
September
1,
1821,
in
referring
to
the
'Enchanted
Lyre,'
beholds
the
prospect
of
an
opera
being
performed
at
the
King's
Theatre,
and
enjoyed
at
the
Hanover
Square
Rooms,
or
even
at
the
Horns
Tavern,
Kennington.
The
vibrations
are
to
travel
through
underground
conductors,
like
to
gas
in
pipes.
'And
if
music
be
capable
of
being
thus
conducted,'
he
observes,'perhaps
the
words
of
speech
may
be
susceptible
of
the
same
means
of
propagation.
The
eloquence
of
counsel,
the
debates
of
Parliament,
instead
of
being
read
the
next
day
only,--But
we
shall
lose
ourselves
in
the
pursuit
of
this
curious
subject.'
Besides
transmitting
sounds
to
a
distance,
Wheatstone
devised
a
simple
instrument
for
augmenting
feeble
sounds,
to
which
he
gave
the
name
of
'Microphone.'
It
consisted
of
two
slender
rods,
which
conveyed
the
mechanical
vibrations
to
both
ears,
and
is
quite
different
from
the
electrical
microphone
of
Professor
Hughes.
