Modern Magic: A Practical Treatise on the Art of Conjuring
·
Professor Hoffmann
375
Now
it
would
seem
at
first
sight
sufficiently
surprising
that
I
should
be
able
merely
to
tell
you
the
number
of
dominoes
which
have
been
moved
in
my
absence,
but
that
might
be
easily
effected
by
confederacy,
or
many
other
very
simple
expedients.
I
propose
to
do
much
more
than
this,
and
to
show
you
not
only
that
I
know
the
number
that
you
have
just
displaced,
but
that
I
can
read
the
dominoes
before
you
as
readily
in
their
present
position
as
though
they
were
lying
face
upwards.
For
instance,
this
domino”
(touching
one
of
the
row
with
your
finger
or
wand)
“represents
the
number
which
have
been
moved
in
my
absence.
Will
some
one
please
to
say
what
that
number
was?”
The
answer
is,
we
will
suppose,
“Seven.”
“Seven,”
you
repeat,
turning
over
the
domino
you
have
touched.
“You
see
that
I
was
right.
Would
you
like
me
to
name
some
more?
They
are
all
equally
easy.
This,
let
me
see--yes,
this
is
a
two;
this
is
a
nine;
this
is
a
double-six;
this
is
a
double-blank;”
turning
over
each
domino
to
show
that
you
have
named
it
right.
