Modern Magic: A Practical Treatise on the Art of Conjuring
·
Professor Hoffmann
418
The
trick
may
be
also
worked
very
effectively
by
using
a
genuine
ball
of
a
different
colour
to
the
shell,
with
the
addition
of
a
duplicate
of
each.
Thus,
if
the
shell
be
black,
you
must
be
provided
with
a
solid
ball
of
the
same
colour,
and
two
red
balls.
One
of
the
latter,
as
also
the
solid
black
ball,
should
be
of
such
a
size
as
to
go
inside
the
shell,
the
remaining
red
ball
being
of
the
same
size
as
the
shell
in
its
complete
condition.
The
half
shells
being
in
their
place
in
the
box,
the
performer
brings
it
forward,
together
with
the
smaller
red
and
black
ball,
keeping
the
remaining
red
ball
concealed
in
his
palm.
Borrowing
a
handkerchief,
he
wraps
(apparently)
the
black
ball
therein,
and
gives
it
to
some
one
to
hold
(really
substituting
the
palmed
red
ball,
and
getting
rid
of
the
black
ball
as
soon
as
he
can
into
one
of
his
secret
pockets).
He
then
places
the
remaining
red
ball
in
the
box,
and
having
covered
it
over,
commands
the
black
ball
in
the
handkerchief
to
change
places
with
the
red
one
in
the
box.
Upon
examination,
the
change
has
apparently
taken
place,
the
red
ball
in
the
box
being
now
enclosed
within
the
hollow
shell,
and
thus
having
all
the
appearance
of
the
solid
black
ball.
