DISTILLATION

OP
DISTILLATION,
AND
THE
APPARATUSES
MADE
USE
OF.
The
apparatus
for
distilling,
upon
which
many
im-
provements
in
France
are
founded,
is
that
of
M.
Adam.
In
a
furnace,
situated
in
one
corner
of
the
distillery,
is
placed
a
still
built
into
the
masonry.
The
head
is
in
the
form
of
a
dome,
solidly
fixed
with
the
cucurbit.
From
the
centre
of
this
dome
a
tube
ascends,
as
thick
as
a
man's
arm
;
and
this
runs
into
the
first
vessel,
placed
on
one
side
of
the
still,
which
is
fixed
upon
strong
joists.
From
this
vessel
issues
a
second
tube,
similar
to
the
first,
but
in
the
form
of
an
arch,
which
enters
into
an-
other
vessel,
also
resembling
the
first,
which
communi-
cates
with
a
third
in
the
same
manner.
In
this
apparatus,
thus
simplified,
there
are
several
points
to
be
considered
In
the
first
place,
all
the
vessels
fixed
upon
the
joists
are
made
in
the
form
of
an
egg,
and
have
their
two
ends
placed
vertically.
Secondly,
that
the
entering
tubes,
viz.
those
which
proceed
from
the
still
to
the
first
egg,
and
from
the
first
to
the second,
&c.
have
their
extremities
in
the
bottom
of
each
egg^
and
there
form
something
like
the
head
of
a
garden
or
watering
pot,
pierced
with
several
holes.
Thirdly,
the
last
of
these
eggs,
when
there
are
but
three,
and
sometimes
the
two
last,
when
there
are
four,
are
furnished
with
a
cooler
in
their
upper
part
;
and
this
is
always
filled
with
water
while
the
distillation
is
going
on.
These
vessels,
with
their
refrigerators,
are
called
condensers.
Every
distiller
does
not
use
condensers
;
the
majority
