An
egg,
immediately
after
it
is
produced,
is
very
clear
and
fine;
but
by
staying
in
the
nest,
and
coming
in
contact
with
the
feet
of
the
bird,
it
soon
assumes
a
dirty
appearance.
To
remedy
this,
wash
it
well
in
soap
and
water,
and
use
a
nail-brush
to
get
the
dirt
off.
The
eggshell
is
now
as
it
ought
to
be,
and
nothing
remains
to
be
done
but
to
prevent
the
thin
white
membrane
(which
is
still
inside)
from
corrupting.
Take
a
wineglass
and
fill
it
with
a
solution
of
corrosive
sublimate
in
alcohol,
then
immerse
the
sharp
end
of
the
eggshell
into
it,
keeping
the
finger
and
thumb
which
hold
the
egg
just
clear
of
the
solution.
Apply
the
mouth
to
the
little
hole
at
the
blunt
end,
and
suck
up
some
of
the
solution
into
the
shell.
There
need
be
no
fear
of
getting
the
liquor
into
the
mouth,
for
as
soon
as
it
rises
in
the
shell
the
cold
will
strike
the
finger
and
thumb,
and
then
the
sucking
must
be
immediately
discontinued.
Shake
the
shell
in
the
same
manner
as
when
the
water
was
in
it,
and
then
blow
the
solution
back
into
the
glass.
The
eggshell
will
now
be
beyond
the
reach
of
corruption;
the
membrane
for
ever
retains
its
pristine
whiteness,
and
no
insect,
for
the
time
to
come,
will
ever
venture
to
prey
upon
it.
If
you
wish
your
egg
to
appear
extremely
brilliant,
give
it
a
coat
of
mastic
varnish,
put
on
very
sparingly
with
a
camel-hair
pencil:
green
or
blue
eggs
must
be
done
with
gum
arabic,
as
the
mastic
varnish
is
apt
to
injure
the
colour.
