Modern Magic: A Practical Treatise on the Art of Conjuring
·
Professor Hoffmann
230
The
secret
lies
in
the
simple
arithmetical
fact,
that
if
you
add
an
odd
number
to
an
even
number
the
result
will
be
odd;
if
you
add
an
odd
number
to
an
odd
number
the
result
will
be
even.
You
have
only
to
take
care,
therefore,
that
the
number
you
yourself
add,
whether
large
or
small,
shall
always
be
odd.
TO
CHANGE
A
FLORIN
INTO
A
PENNY,
BACK
AGAIN,
AND
THEN
TO
PASS
THE
SAME
INVISIBLY
INTO
THE
POCKET
OF
THE
OWNER.--This
is
a
trick
of
genuine
sleight-of-hand,
and
will
test
your
expertness
in
two
or
three
different
passes.
Having
beforehand
palmed
a
penny
in
your
right
hand,
you
borrow
from
one
of
the
company
a
florin
(or
half-crown),
requesting
the
owner
to
mark
it
in
such
manner
that
he
may
be
able
to
identify
it.
Make
him
stand
up
facing
you,
your
own
right
side
and
his
left
being
towards
the
audience.
Taking
the
marked
florin
between
the
fingers
and
thumb
of
the
right
hand
(the
back
of
which,
from
your
position,
will
be
toward
the
spectators),
you
ask
him
whether
he
is
nervous,
whether
he
can
hold
fast,
and
so
on.
On
receiving
satisfactory
replies,
you
state
that
you
are
about
to
put
him
to
the
test,
and
request
him
to
hold
out
his
right
hand,
telling
him
that
you
are
about
to
count
three,
and
that
at
the
word
“three”
you
will
drop
the
florin
into
his
hand,
which
he
is
to
close
tightly
upon
it.
You
accordingly
count,
“One!
two!
three!”
each
time
making
a
motion
as
of
dropping
the
florin
into
his
hand,
and
at
the
word
“three”
actually
do
drop
it,
when
he
closes
his
hand
upon
it,
as
directed;
but
you
are
not
satisfied.
