Leeches
and
their
Application.
The
leech
used
for
medical
purposes
is
called
the
hirudo
medicinalis
to
distinguish
it
from
other
varieties,
such
as
the
horse-leech
and
the
Lisbon
leech.
It
varies
from
two
to
four
inches
in
length,
and
is
of
a
blackish
brown
colour,
marked
on
the
back
with
six
yellow
spots,
and
edged
with
a
yellow
line
on
each
side.
Formerly
leeches
were
supplied
by
Lincolnshire,
Yorkshire,
and
other
fenny
countries,
but
latterly
most
of
the
leeches
are
procured
from
France,
where
they
are
now
becoming
scarce.
843.
When
Leeches
are
Applied
When
leeches
are
applied
to
a
part,
it
should
be
thoroughly
freed
from
down
or
hair
by
shaving,
and
all
liniments,
&c.,
carefully
and
effectually
cleaned
away
by
washing.
If
the
leech
is
hungry
it
will
soon
bite,
but
sometimes
great
difficulty
is
experienced
in
getting
them
to
fasten.
When
this
is
the
case,
roll
the
leech
into
a
little
porter,
or
moisten
the
surface
with
a
little
blood,
or
milk,
or
sugar
and
water.
Leeches
may
be
applied
by
holding
them
over
the
part
with
a
piece
of
linen
cloth,
or
by
means
of
an
inverted
glass,
under
which
they
must
be
placed.
844.
When
applied
to
the
Gums
When
applied
to
the
gums,
care
should
be
taken
to
use
a
leech
glass,
as
they
are
apt
to
creep
down
the
patient's
throat:
a
large
swan's
quill
will
answer
the
purpose
of
a
leech
glass.
When
leeches
are
gorged
they
will
drop
off
themselves;
never
tear
them
off
from
a
person,
but
just
dip
the
point
of
a
moistened
finger
into
some
salt
and
touch
them
with
it.
