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 of the head and the back of the head are stroked similarly. After this the whole head is rubbed briskly with the finger-points. This should be done often, even four or five times in the day. If the patient objects, it is being unskilfully done; the right sort of rubbing is always pleasant. A squinting eye has been cured in a few rubbings, where the case was a simple one. If the head becomes very hot, it may be cooled as directed above for Children's Sleep. Squinting may be produced or increased by that state of the stomach and bowels in which worms are bred.
