CONTINUOUS
DISTILLATION.

as
to
cause
the
perfect
distillation
of
the
liquor
in
its
passage
to
the
regulating
tube.
The
spirit
which
rises
in
the
head
of
this
improved
still
will
be
found
much
stronger
and
purer
than
that
ob-
tained
from
stills
of
the
ordinary
construction,
where
the
spirituous
vapour
is
much
mixed
with
aqueous
matter
and
other
impurities.
The
channels
may
be
extended
to
any
length
required,
over
a
bottom
of
any
dimensions,
by
contracting
their
breadth.
Stills
upon
this
principle
may
be
made
of
all
sizes
and
shapes,
round,
square,
or
other-
wise
;
and
the
partitions
may
be
placed
in
concentric
or
eccentric
circles,
with
openings
on
their sides
at
such
dis-
tances
as
shall
cause
the
liquor
to
flow
over
the
most
ex-
tended
surface
of
bottom
;
or
the
still
may
be
square,
with
angular
partitions
ranged
as
a
labyrinth,
or
in
any
other
manner,
so
as
to
cause
the
run
of
the
liquor
to
be
greatly
extended
over
the
surface
of
the
boiler.
The
bottom
of
these
stills
may
be
either
flat,
concave,
convex,
conical,
or
of
any
other
form
;
and
the
entrance
of
the
liquor
into
the
still,
and
also
its
discharging
aper-
ture,
may
be
at
the
side,
in
the
middle,
or
elsewhere^
as
circumstances
may
dictate.
Boilers
or
evaporators
may
be
made
on
this
plan,
either
with
or
without
heads,
and
their
capacity
of
working
may
in
all
cases
be
increased
by
placing
layers
of
pipes,
connected
thereto,
within
the
flues,
between
the
still
and
chimney
;
which
pipes
may
be
bent
or
coiled
in
a
serpentine
direction
or
in
any
other
position,
and
the
liquor
to
be
operated
upon
made
to
pass
through
them
previous
to
its
entering
the
still
:
thus
the
operation
may
be
advanced
to
any
required
state
of
for-
wardness.
