s these knots grow large and swell
the eyelid, and at times the matter in them grows hard, and seems to
take up a lasting abode in that tissue. Strong and destructive liquids
or powders are sometimes applied, that so affect the whole substance of
the eye as to cause blindness. Nothing of this nature is required at
all. First, the skin of the head must be dealt with. You will find that
this is hot and dry, and somewhat hard on the skull. Rub this gently
with the dry hands for a few minutes, then press a cloth tightly wrung
out of cold water all round the head. Rub and cool alternately for
half-an-hour or more if it continues to produce an agreeable feeling.
When the head is all soothed, and good action has been secured, at
least on its surface, begin with the eye itself. The same treatment is
required for both classes of cases. The eye will be shut at first. You
take a fine camel's-hair brush, such as is used by artists, and some
vinegar or acetic acid, so weak that you can swallow a portion of it
without hurting your throat. This is a very good test of strength for
the acid. You carefully brush over the outside of the eyelids and all
round the eye with this weak acid. This must be done most carefully and
patiently for a length of time, till all sweatiness is washed off, and
a fine warm feeling is produced by the acid. The matter softens and
breaks up, so that it begins to pass away. We have seen a little ball
of hard white matter break up and come away after a single brushing
carefully done. When the matter is in the eyelid, and is so situated
that you can brush over it in the inside of the lid, it is well to do
so; but this operation must be gently and carefully done. When you have
brushed with the acid long enough, dry the eyelids and cheek carefully,
and rub with a little fresh olive or almond oil. It will be well to
cover the eye from the cold, and from any dust that might irritate. You
will soon find that it is as clear and sound as could be wished.

Eyes, Squinting.--Various affections of the eyeball muscles cause this.
To cure it is often easy, sometimes very difficult. The method of
treatment is to stimulate all the nerves of the head and face, and at
the same time to soothe their irritation. This is accomplished by
massaging the brow and entire head. It must be gently and soothingly
done. The open hands are drawn upwards over the brow from the eyebrows,
the rubber standing behind the patient. Then both sides o
