tubes
the
extremities
of
which
are
bent
down
into
the
liquid
flowing
through
the
still.
The
steam
from
the
boiler
passes
up
the
tube

into
the
hollow
vessels
c,
c,
and
thence
through
the
tubes

into
the
smaller
curved
pipes
e,

the
extremities
of
which
it
pervades
the
liquid
in
its
progress.
If
it
should
be
deemed
more
advantageous
to
transmit
the
caloric
from
the
steam
through
the
metal,
without
allowing
the
steam
to
pass
into
the
liquid,
it
may
be
done
by
closing
the
ex-
tremities
of
the
curved
pipes
e,
e,
e,
and
placing
them
in
a
horizontal
position,
with
a
small
inclination,
in
order
to
allow
the
condensed
steam
to
pass
into
the
boiler.
Here
the
spirit
arising
in
one
still
might
pass
into
an-
other,
and
be
again
operated
upon;
and
distillings
of
every
degree
and
of
various
substances
may
be
carried
on
in
one
continued
operation
at
the
same
time
and
by
one
nic
derate
fire,
which^
upon
this
principle,
will
suffice
for
