The Fairy-Land of Science

But
I
fancy
I
see
two
or
three
little
questioning
faces
which
seem
to
say,
"I
see
no
yellow
bags
at
the
top
of
the
tube."
Well,
I
cannot
tell
whether
you
can
or
not
in
the
specimen
you
have
in
your
hand;
for
one
of
the
most
curious
things
about
primrose
flowers
is,
that
some
of
them
have
these
yellow
bags
at
the
top
of
the
tube
and
some
of
them
hidden
down
right
in
the
middle.
But
this
I
can
tell
you:those
of
you
who
have
got
no
yellow
bags
at
the
top
will
have
a
round
knob
there
(I
a,
Fig.
43),
and
will
find
the
yellow
bags
(b)
buried
in
the
tube.
Those,
on
the
other
hand,
who
have
the
yellow
bags
(2
b,
Fig.
43)
at
the
top
will
find
the
knob
(a)
half-way
down
the
tube.
