Eyes, Paralysis of.--The partial paralysis of the muscles of one eye produces double vision, so that the patient sees two similar objects where there is only one. This double vision is often, however, the result of stomach derangement. If so, it may soon pass away. The true paralysis is more persistent. To cure this, rub the entire skin of the head gently and steadily with the hands and finger-tips (stroking always _upwards_) for some fifteen minutes. Then apply cold cloths to the eyes as already directed. If the cold cloths are uncomfortable, hot ones should be tried. Do this for fifteen minutes also. Continue alternately for an hour twice or three times a day. We have known one such day's treatment remove the double vision _entirely_, and no relapse occur, but in most cases the treatment must be persevered in and returned to until the paralysis is overcome. Eyes, Spots on.--These spots are of two different kinds, and yet they are very much the same in nature and substance. What is called "a cataract" is of a different character. We refer not to this, but to the spots that form on the surface of the eyeball, and those that form in the membrane of the eyelid. When inflammation has gone on for some time on the eyeball itself, portions of whitish matter form on the glassy surface and soon interfere with the sight. When inflammation has gone on in the eyelid, little knots like pin-heads form, producing a feeling as if sand were in the eye. Afterwards 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.
