What
color
is
this?
Black.
What
is
the
color?
Blue.
Tell
me
the
color?
Green.
Has
it
a
color?
White.
Any
color?
Orange,
yellow.
Name
the
color?
Brown.
Please
name
the

Red.
These
have
only
to
be
learned
by
two
persons
in
combination,
when
they
will
be
able
to
tell
the
color
of
any
article.
Should
the
exhibitor
have
an
article
of
a
mixed
color,
say,
mauve,
he
first
asks
the
question
having
red
for
the
answer;
and
then,
before
the
reply
can
be
given,
again
puts
the
query
for
blue.
The
clairvoyant
thereby
knowing
it
is
a
mixture
of
red
and
blue,
he
is
able
to
know
that
mauve
is
the
answer
required.
Again,
in
asking
the
nature
of
a
stone
set
in
a
jewel
the
question
may
be
thus
arranged:
What
is
the
stone?
Topaz.
What
stone
is
it?
Jet.
Tell
me
the
stone?
Emerald.
Name
the
stone?
Diamond.
Do
you
know
the
stone?
Cornelian.
Any
stone?
Amethyst.
And
so
on
ad
infinitum.
In
ascertaining
the
nature
of
a
piece
of
jewelry
the
questions
may
be
put
thus:
What
is
the
metal?
Gold.
What
metal
is
it?
Brass.
What
metal?
Silver.
Tell
me
the
metal?
Copper.
Name
the
metal?
Iron;
steel.
Please
name
the
metal?
Bronze.
Can
you
tell
me
the
metal?
Tin.
The
following
questions,
having
replies
for
the
usual
articles
found
upon
persons
assembled
to
witness
a
performance,
may
easily
be
learned
by
a
person
gifted
with
a
good
memory,
or
by
a
person
with
an
ordinary
memory
by
repeated
application:
