Modern Magic: A Practical Treatise on the Art of Conjuring
·
Professor Hoffmann
733
The
writing
by
“spirits”
on
the
ceiling
is
done
in
this
way.
The
medium
is
bound,
and
when
the
room
is
lighted
a
written
answer
to
a
question
asked
is
put
upon
the
ceiling.
The
reader
will
have
already
guessed
that
this
is
performed
by
the
medium
by
means
of
the
telescopic
tube,
at
the
end
of
which
he
places
a
piece
of
chalk.
He
rubs
the
chalk
on
his
head,
to
“show”
that
the
spirits
had
raised
him
to
the
ceiling,
as
if
he
had
performed
the
feat
with
his
head.
Another
“crucial”
test
which
these
mediums
offer
is
known
as
the
invisible
writing.
One
of
the
company
is
asked
to
write
a
sentence
or
a
number
of
figures
upon
a
piece
of
paper.
This
paper
is
carefully
folded,
the
lights
are
extinguished.
In
a
few
seconds
they
are
again
relighted,
when
the
medium
declares
that
the
spirits
have
told
him
the
contents
of
the
paper,
and
he
reads
the
sentences
or
tells
the
figures.
Again,
the
medium
asks
a
gentleman
to
put
the
hands
of
a
watch
to
any
hour
he
chooses,
and,
when
again
the
lights
are
lowered,
he
calls
out
the
exact
time
to
the
exact
minute.
This
all
seems
very
mysterious
and
unaccountable,
but
I
shall
again
show
that
we
do
not
require
spirit
aid
to
perform
these
marvels.
The
medium
has
in
his
pocket
a
small
phial
containing
phosphorus
and
oil;
and
when
this
test
is
performed
there
is
invariably
a
long
cloth
on
the
table.
When
the
papers
upon
which
the
sentence
or
figures
are
written,
or
the
watch,
are
placed
on
the
table,
the
lights
are
lowered,
and
the
performer
stoops
beneath
the
table,
takes
the
paper
or
watch,
opens
the
phial,
from
which
a
blue
flame
is
emitted,
and
by
this
light
he
reads
the
sentence,
or
figures,
or
sees
the
time.
He
replaces
the
articles,
and
can,
of
course,
readily
tell
what
he
has
read
or
seen.
