THE
BALL
WHICH
CHANGES
TO
A
ROSE.--This
is
little
more
than
an
enlarged
edition
of
the
apparatus
just
described,
the
ball
in
Morison’s
pill-box
being
generally
of
about
an
inch
and
a
half
in
diameter,
while
in
the
present
case
the
ball
is
nearly
double
that
size.
(See
Fig.
131.)
The
only
other
difference
is
the
addition
of
a
short
pin,
about
a
sixteenth
of
an
inch
in
length,
projecting
from
the
bottom
of
the
cup,
and
fitting
into
a
corresponding
hole
in
the
lower
shell.
The
addition
of
this
pin
enables
the
performer,
after
having
pressed
the
stud
at
top,
and
thus
caused
the
ball
to
appear
in
the
previously
empty
box,
to
again
cause
its
disappearance.
This
is
effected
by
opening
the
box
with
a
slight
lateral
pressure,
when
the
pin
acts
as
a
stop
or
check
to
hold
back
the
lower
shell;
and
the
shells
which
are
in
this
instance
made
to
fit
rather
more
loosely
together,
are
thus
forced
to
separate
again,
the
lower
being
left
in
the
cup
and
the
upper
in
the
lid,
as
before.
