Modern Magic: A Practical Treatise on the Art of Conjuring
·
Professor Hoffmann
639
An
examination
of
Fig.
300,
representing
a
ground
plan
of
the
cabinet,
will
make
plain
the
seeming
mystery.
A
moveable
flap
a
b,
working
on
hinges
at
b,
extends
from
top
to
bottom
of
each
side,
resting
when
thrown
open
against
the
post
c
in
the
middle,
and
thus
enclosing
a
triangular
space
at
the
back
of
the
cabinet.
The
outer
surfaces
of
these
flaps
(i.e.,
the
surfaces
exposed
when
they
are
folded
back
against
the
sides
of
the
cabinet)
are,
like
the
rest
of
the
interior,
covered
with
wall
paper,
of
a
crimson
or
other
dark
colour.
The
opposite
sides
of
the
flaps
are
of
looking-glass,
and
when
the
flaps
are
folded
back
against
the
posts,
reflect
the
surfaces
against
which
they
previously
rested,
and
which
are
covered
with
paper
of
the
same
pattern
as
the
rest.
The
effect
to
the
eye
of
the
spectator
is
that
of
a
perfectly
empty
chamber,
though,
as
we
have
seen,
there
is
in
reality
an
enclosed
triangular
space
behind
the
post.
This
is
capable
of
containing
two
or
three
persons,
and
here
it
is
that
the
persons
and
things
intended
to
appear
in
succession
are
concealed.
The
assistant,
entering
in
sight
of
the
audience,
changes
places,
as
soon
as
the
door
is
closed,
with
one
of
the
other
persons.
This
person
having
retired,
and
the
door
being
again
closed,
those
who
are
still
within
place
the
skeleton
in
position
in
front
of
the
post,
and
again
retire
to
their
hiding-place.
When
all
the
rest
have
appeared,
the
person
who
first
entered
presses
the
flaps
against
the
sides
of
the
cabinet,
against
which
they
are
retained
by
a
spring
lock
on
each
side,
and
the
public
may
then
safely
be
admitted,
as
their
closest
inspection
cannot
possibly
discover
the
secret.
