A
tolerably
thick
charcoal
ventilator,
as
described
above,
could
be
very
advantageously
applied
to
the
gully-holes
of
common
sewers,
and
to
the
sinks
in
private
dwellings,
the
foul
water
in
both
cases
being
carried
into
the
drain
by
means
of
tolerably
wide
syphon
pipes,
retaining
always
about
a
couple
of
inches
of
water.
Such
an
arrangement
would
effectually
prevent
the
escape
of
any
effluvia,
would
be
easy
of
construction,
and
not
likely
to
get
soon
out
of
order.
In
respirators
for
the
mouth
the
air
is
made
to
pass
through
a
quarter
of
an
inch
of
coarsely
powdered
charcoal,
retained
in
its
place
by
two
sheets
of
silvered
wire
gauze,
covered
over
with
thin
woollen
cloth,
by
which
means
its
temperature
is
greatly
increased.
The
charcoal
respirator
possesses
a
decided
advantage
over
respirators
of
the
ordinary
construction,
in
that
all
disagreeable
effluvia
are
absorbed
by
the
charcoal,
so
that
comparatively
pure
air
is
alone
inhaled.
Adaptations
may
be
made
to
cover
the
nostrils
as
well
as
the
mouth,
for
protecting
the
wearer
against
fevers
and
other
infectious
diseases,
and
chiefly
for
use
in
chemical
works,
common
sewers,
&c.,
to
protect
the
workmen
from
the
noxious
effects
of
the
deleterious
gases
to
which
they
are
frequently
exposed.
1777.
Charcoal
applied
to
Sores,
&c.
Charcoal
powder
has
been
most
successfully
employed
at
hospitals,
to
arrest
the
progress
of
gangrene
and
other
putrid
sores.
The
charcoal
does
not
require
to
be
put
immediately
in
contact
with
the
sores,
but
is
placed
above
the
dressings,
not
unfrequently
quilted
loosely
in
a
little
cotton
wool.
In
many
cases
patients
who
were
rapidly
sinking
have
been
restored
to
health.
