e put on with a view to the necessary
bending of the knee in walking and sitting, if the patient is expected
to use the leg.

8. Never apply a wet bandage, as you cannot judge of just how much
pressure will be exerted when the bandage dries, because of the
shrinkage of cloth with drying; much greater in some cloth than in
others.

Kinds of roller bandages:

1. Circular for parts uniform in size, as the body.

2. Spiral for conical surfaces, as fingers or toes.

3. Reverse for more conical surfaces, as arms and legs.

_Circular Bandages_--Any part of the body which is of uniform size may
be covered with a circular bandage. Each turn covers about two-thirds of
the previous turn. This holds each turn firmly and prevents slipping and
exposing the dressing or wound underneath. Bandage in general direction
of the return of the blood to the heart. Fasten the bandage with a strip
of adhesive plaster or safety pin. If there is possibility of
restlessness or much activity on the part of the patient, it is best to
run several narrow strips of adhesive plaster along the whole width of
the bandage when finished to prevent possible slipping of the turns of
the bandage when the muscles move under it with the activity of the
patient. This is especially true of a body bandage.

_Spiral Bandage_--A conical part, if not too conical, may be covered
with a spiral bandage. Each turn ascends at a slight angle, with one
edge of the bandage a little tighter than the other. In putting on this
kind of bandage it is necessary to learn to have the tight edges all of
a uniform pressure and each turn overlap the turn below in such a way
that these tight edges make the uniform pressure without regard to the
upper edge underneath, which is covered in each turn by the tighter edge
of the turn above it.

_Reverse Bandages_--The reverse bandage is a modification of the spiral
one, in order to cover the gapping between spirals which occurs when the
surface is very conical, as, for instance, on the leg.

In putting on this bandage the loose end is caught by two or three turns
first as in other bandages. Then start to make a spiral turn, but at the
mid point of the front of the part being bandaged place the thumb of the
left hand, and fold the bandage down so that it lies smoothly and
continue the turn around to that same point. Repeat the process with
each turn. (See illustration.) Each turn covers two-thirds of the one
below in order to hold fir
