CONTINUOUS

losing
any
tiling
in
the
wine,
while
the
portion
of
watery
vapour
will
be
condensed,
and
produce
a
relative
q-tiantity
of
alcoholic
vapours.
Such
are
the
phenomena
which
take
place
in
the
systems
in
which
one
still
is
distilled
by
the
other.
Such
are,
also,
the
phenomena
which
aro
observed
in
the
distilling
column
and
in
the
rectifier
of
the
apparatus
now
under
consideration.
The
nearer
the
vapours
are
to
the
summit
of
the
column
the
richer
the
wine
they
meet,
and
the
more
they
are
charged
with
alcohol.
As,
in
this
case,
the
wine
operated
upon,
and
such
as
it is
supplied
by
the
condenser,
is
the
richest,
and
as
these
vapours
are
greatly
charged
with
alcohol
when
they
leave
the
column
to
enter
the
condenser,
it
must
be
con-
ceived
that
this
column
has
an
immense
advantage
of
other
stills
;
and
that
it
serves
only
and
continuously
to
enrich
the
vapours,
without
ever
enriching
the
wine;
while
in
other
apparatus
it
is
always
necessary
to
render
the
wine
rich
before
richer
vapours
can
be
obtained.
The
same
phenomenon
takes
place
in
the
rectifier.
The
low
wines,
which
run
back
into
it,
present
to
the
vapour
a
liquid
much
richer
in
alcohol
than
that
which
it
has
met
in
the
column
;
but
these
low
wines
only
appropriate
to
themselves
the
water
of
these
vapours,
to
which
they aban-
don
a
portion
of
their
alcohol.
The
spirituous
vapours^
on
leaving
the
rectifier,
enter,
through
h,
into
the
worm
of
the
wine-warming
condenser
:
even
in
this
part
of
the
apparatus
they
may
be
more
dephlegmed,
and
from
these
they
pass
into
the
worm.
In
this
apparatus
every
thing
is
combined
in
such
a
manner
as
to
cause
all
the
vapours
that
are
produced
to
be
condensed
in
the
wine-
warming
