THE
COMPLETE
PRACTICAL
DISTILLER.
from
the
centre
of
the
head
or
dome,
and
descends
to
the
bottom
of
the
egg,
where
it
enlarges
into
the
form
of
the
rose
of a
garden
watering-pot,
pierced
with
a
number
of
holes.
It
must
be
understood
that
this
tube
is
soldered
to
the
egg
at
its
entrance,
to
prevent
any
other
issue
of
the
vapours
but
by
the
way
intended.
The
first
egg
communicates
with
the
second,
this
with
tha
third,
and
so
on
to
the
last,
by
means
of the
tube
M,
which
is
soldered
to
the
first
egg
at
the
point
K,
and
pro-
ceeds
to
the
bottom
of
the
following,
where
it
enlarges
in
the
form
of
a
watering-pot,
as
in
the
first.
The
last
egg
is
furnished
with
the
cooler
N,
by
means
of
which
the
su
perior part of
the
egg,
where
the
vapours
are
collected,
is
encircled
with
water
to
commence
the
refrigeration.
This
cooler
is
supplied
with
a
cock
o,
to
let
out
the
water
when
it
gets too
warm.
Every
condenser
is
furnished
with
a
cock
like
this,
or
otherwise
their
upper
parts
are
plunged
into
the
common
tub
full
of
water.
This
tub
or
bag,
often
made
of
copper,
has
the
form
of
a
parallelepiped.
The
tube
R
communicates
from
the
second
egg
with
the
worm,
which
is
generally
used
with
two
eggs,
sufficient
to
obtain
brandy
at
18°,
when
they
close
the
cock M,
which
communicates
with
the
second
and
third
egg,
and
they
open
the
cock
r
to
establish
the
conanunication
with
the
worm.
The
pipe
s
communi-
cates
between
the
third
egg
and
the
worm.
When
three
eggs
are
used,
they
operate
as
just
indicated;
they
open
the
cocks
M
and
s,
and
stop
the
cock
r.
The
same
pro-
ceeding
is
observed
when
the
greatest
number
of
eggs
are
i*ni
ployed.
Each
of
these
has
a
tube
that
communicates
with
the
