SPECIAL
DISTILLATIONS.

According
to
the
obseryations
of
M.
Aubergier,
it
would
appear
that
this
oil
is
seated
in
the
skin of
the
rai-
sin
itself,
and,
from
the
facts
which
he
relates,
his
opinion
is
likely
to
be
true.
Kernels
distilled
with
alcohol
or
water
have
given
a
liquor
of
an
agreeable
taste.
'^
The
stalks
have
produced,
by
distillation,
a
liquor
slightly
alcoholized,
having
neither
the
taste
nor
the
fla-
vour
of
lees-brandy.
But
the
envelope
of
the
raisin,
separated
from
the
kernels
and
from
the
stalks,
when
submitted
to
distillation,
after
having
been
fermented,
have
given
a
spirit
in
all
respects
similar
to
that
of
lees.
Thus
it
appears
clearly
demonstrated
by
these
experi-
ments
that
the
seat
of
the
oil,
which
communicates
to
the
lees-brandy
its
bad
qualities,
is
in
the
skin
of
the
raisin.
M.
Aubergier
has
succeeded
in
obtaining
this
oil
by
rec-
tifying
lees-spirit
at
a
moderate
heat.
**
The
first
portions
of
alcohol
which
came
over
had
much
less
acridity
than
those
that
followed
:
on
having
been
rectified
a
second
time,
they
were
almost
entirely
free
from
it
;
but
repeated
rectifications
could
not
give
it
so
agreeable
a
taste
as
that
possessed
by
the
spirit
pro-
duced
from
wine.
The
latter
portions
of
liquid
in
each
operation,
reunited
and
distilled,
gave,
at
first,
alcohol,
which
the
addition
of
water
did
not
render
troubled,
and
which
contained
but
little
oil.
**The
portions
which
were
afterward
obtained
were
transparent,
but
they
became
troubled
when
mixed
with
water
;
the
third
portion,
which
remained
milky
until
the
end
of
the
operation,
had
on
its
face
a
light
couch
of
oil,
although
it
marked
23°
Beaume.
