Modern Magic: A Practical Treatise on the Art of Conjuring
·
Professor Hoffmann
380
After
having
exhibited
the
trick
in
this
form
once
or
twice,
you
may
vary
your
mode
of
operation.
For
this
purpose
take
the
dice
(still
retaining
their
relative
position)
horizontally
between
the
thumb
and
second
finger,
in
the
manner
depicted
in
Fig.
117,
showing
“three-one”
on
their
upper
face;
the
corresponding
“three-one,”
or
rather
“one-three,”
being
now
covered
by
the
forefinger.
As
the
points
on
the
opposite
faces
of
a
die
invariably
together
amount
to
seven,
it
is
obvious
that
the
points
on
the
under
side
will
now
be
“four-six,”
while
the
points
next
to
the
ball
of
the
thumb
will
be
“six-four.”
You
show,
alternately
raising
and
lowering
the
hand,
that
the
points
above
are
“three-one,”
and
those
below
“six-four.”
Again
going
through
the
motion
of
rubbing
the
dice
with
the
opposite
forefinger,
you
slightly
raise
the
thumb
and
depress
the
middle
finger,
which
will
bring
the
“six-four”
uppermost,
and
the
“three-one”
or
“one-three”
undermost.
This
maybe
repeated
any
number
of
times;
or
you
may,
by
moving
the
thumb
and
finger
accordingly,
produce
either
“three-one”
or
“six-four”
apparently
both
above
and
below
the
dice.
The
trick
may,
of
course,
be
varied
as
regards
the
particular
points,
but
the
dice
must,
in
any
case,
be
so
placed
as
to
have
similar
points
on
two
adjoining
faces.
TO
NAME,
WITHOUT
SEEING
THEM,
THE
POINTS
OF
A
PAIR
OF
DICE.--This
is
a
mere
arithmetical
recreation,
but
it
is
so
good
that
we
cannot
forbear
to
notice
it.
You
ask
the
person
who
threw
the
dice
to
choose
which
of
them
he
likes,
multiply
its
points
by
two,
add
five
to
the
product,
multiply
the
sum
so
obtained
by
five,
and
add
the
points
of
the
remaining
die.
On
his
telling
you
the
result,
you
mentally
subtract
twenty-five
from
it,
when
the
remainder
will
be
a
number
of
two
figures,
each
representing
the
points
of
one
of
the
dice.
