soap lather until morning. It may then be sponged, dried, and a
little hot olive oil rubbed into the skin. In a serious case, where the
patient is in bed, this treatment may be given night and morning.
Always, in treating such a head, be very gentle, for the least touch is
often painful to the irritated skin. The use of a pure and proper
pomade, such as some preparation of vaseline, is of importance where
the skin is dry, and tends powerfully to preserve the skin and hair in
healthy condition.

Careful brushing of the hair, and rubbing of the skin of the scalp
will, too, be of use. _See_ Hair.

Head, Soaping.--Have a piece of M'Clinton's soap, a good shaving brush,
and a bowl of warm water. Rub the wet brush on the soap, and work the
lather up in the hollow of the left hand, taking more soap and water in
the brush as necessary, until the left hand is full of creamy, thick
lather. Lay this on all over the patient's head. Make another handful,
and lay that on also. The lather may be wrought into the mass of hair
until it reaches the skin, the brush being dipped in the warm water,
and used to work the lather well into the skin of the head. This must
be continued until the whole head is thickly covered with fine white
lather, like a wig in appearance. You need have no difficulty with ever
so much hair. You only comb that nicely back at first, and place the
soap lather on the fore part of the head. Then you bring the hair
forward, and soap the back part. You may work on at this process for
half-an-hour. You will by that time have produced a most delightful
feeling in both body and mind of your patient. Tie a soft handkerchief
over all, and leave for as long as needed--even all night if required.
When removing the lather, use a sponge and warm vinegar or weak acid
(_see_ Acetic Acid), and dry gently with a soft towel. This application
can be used with good effect in all cases of hard, dry skin on the
head, and formation of white scurf. It preserves the hair, and
stimulates its growth. It also removes the painful sensitiveness to
touch so often felt in the hair and head skin. Care must ever be taken
to do it all with a gentle hand. So done it is priceless in its
soothing and healing effects on irritable nerves.

Head, Sounds in.--As the result and accompaniment of deafness these are
sometimes most distressing, even preventing the patient from sleeping.
They are often caused by chill producing some inflammation of the ea
