THE
REVERSIBLE
CANISTER.--This
is
another
piece
of
apparatus
more
particularly
designed
for
changing
a
handkerchief,
though
equally
available
for
many
other
exchanges.
In
appearance
it
is
an
ordinary
cylindrical
canister,
closed
with
a
cap,
and
similar
in
shape
to
those
in
which
tea
is
kept,
but
of
smaller
size,
being
only
five
to
six
inches
in
height.
In
reality,
however,
that
which
appears
to
be
the
body
of
the
canister
is
a
mere
tube,
within
which
slides
up
and
down
an
inner
canister,
which
is
made
double-headed,
i.e.,
like
two
shallow
canisters
placed
bottom
to
bottom.
(See
Fig.
108.)
The
pattern
of
the
outer
tube
is
alike
at
top
and
bottom,
so
that
whether
the
combined
canister
is
as
shown
in
the
figure,
with
compartment
a
uppermost,
or
turned
upside
down,
with
compartment
b
pushed
into
view,
the
appearance
to
the
eye
of
the
spectator
is
the
same.
The
canister
is
prepared
by
placing
beforehand
in
one
or
other
of
the
compartments,
say
b,
a
piece
of
cambric,
as
much
like
a
lady’s
handkerchief
as
possible.
Compartment
a
is
then
pushed
upwards,
as
shown
in
the
figure.
Borrowing
a
handkerchief,
the
performer
requests
the
owner
to
place
it
for
safe
keeping
in
the
canister,
which
he
brings
forward
for
that
purpose.
As
he
turns
to
replace
it
on
the
table,
he
takes
advantage
of
the
moment
during
which
his
back
is
towards
the
spectators
to
push
down
a
(thus
pushing
out
b
at
the
opposite
end
of
the
tube),
and
at
the
same
time
to
turn
over
the
canister,
which,
when
placed
on
the
table,
will
still
look
as
shown
in
the
figure,
but
will
have,
in
reality,
b
uppermost.
Presently
taking
out
the
prepared
cambric,
which
the
spectators
take
to
be
the
handkerchief,
he
burns
or
otherwise
disposes
of
it,
to
be
subsequently
reproduced
by
the
simple
process
of
again
reversing
the
canister.
