THE
APPARATUS.
The
still
is
filled
with
water,
which
is
brought
to
ebullition.
When
the
distilled
water
runs
out
of
the
worm
the
operation
should
commence.
Cock

is
about
half
opened,
so
as
only
to
give
passage
to
half
of
the
wine
it
is
capable
of
furnishing.
The
interior
a
of
the
head
is
filled
with
water
by
cock
No.

The
wine
runs
through
the
funnel
j
into
the
middle
of
the
envelope
H,
which
is
filled
as
high
as
the
tube
K
;
it
enters
then
through
ihis
tube
into
the
lower
part
of
the
envelope,
and,
when
the
latter
is
full,
the
wine
runs
from
this
part
through
the
tube
L
on
the
evaporator.
The
wine
runs
on
the
evaporator
of
the
first
column
on
which
it is
dis-
tilled;
and
the
spent-wash
runs
out
at
the
bottom
of
the
column.
The
spirituous
vapours
rise
into
the
head
D,
and
proceed
through
M
into
the
upper
part
of
the
second
column;
they
then
rise
into
the
pipes of
the
head,
in
which
they
may
be
more
or
less
condensed
;
the
spirituou?
vapors
alone
can
traverse
it,
and
the
phlegms
return
back
into
the
first
column
and
are
again
distilled
before
coming
into
the
still.
In
this
operation the
wine
is
dis-
tilled
on
the
evaporator
of
the
first
column,
the
phlegms
on
the
evaporator
of
the
second,
and
the
spent-wash
falls
