The Fairy-Land of Science

But
now,
instead
of
trying
to
master
this
dry,
hard
passage,
take
Mr.
Huxley's
penny
lecture
on
'Coral
and
Coral
Reefs,'
and
with
the
piece
of
coral
in
your
hand
try
really
to
learn
its
history.
You
will
then
be
able
to
picture
to
yourself
the
coral
animal
as
a
kind
of
sea-anemone,
something
like
those
which
you
have
often
seen,
like
red,
blue,
or
green
flowers,
putting
out
feelers
in
sea-water
on
our
coasts,
and
drawing
in
the
tiny
sea-animals
to
digest
them
in
that
bag
of
fluid
which
serves
the
sea-anemone
as
a
stomach.
You
will
learn
how
this
curious
jelly
animal
can
split
itself
in
two,
and
so
form
two
polyps,
or
send
a
bud
out
of
its
side
and
so
grow
up
into
a
kind
of
"tree
or
bush
of
polyps,"
or
how
it
can
hatch
little
eggs
inside
it
and
throw
out
young
ones
from
its
mouth,
provided
with
little
hairs,
by
means
of
which
they
swim
to
new
resting-places.
You
will
learn
the
difference
between
the
animal
which
builds
up
the
red
coral
as
its
skeleton,
and
the
group
of
animals
which
build
up
the
white;
and
you
will
look
with
new
interest
on
our
piece
of
white
coral,
as
you
read
that
each
of
those
little
sups
on
its
stem
with
delicate
divisions
like
the
spokes
of
a
wheel
has
been
the
home
of
a
separate
polyp,
and
that
from
the
sea-water
each
little
jelly
animal
has
drunk
in
carbonate
of
lime
as
you
drink
in
sugar
dissolved
in
water,
and
then
has
used
it
grain
by
grain
to
build
that
delicate
cup
and
add
to
the
coral
tree.
