Take the A D current, mild force. Introduce the ear electrode as the N. P. when the disease is of long standing, or as the P. P. when it is of recent origin. Apply the opposite pole to the back of the neck. Treat five to eight minutes, once a day for three or four days, and afterwards three times a week. If no success appears within three weeks, it will probably be vain to expect it afterwards. NOISES IN THE HEAD. Treat the same as for deafness. INFLAMED EYES. If the disease be recent and acute, (but not infectious), as from sewing or reading by lamp light or other irritation, take the C D current, of moderate force. Treat with the eye-bath, filled with tepid water, having the eye open in the water. Make the bath the P. P., and place the N. P. on the spine at the upper dorsal vertebra. Treat each eye three minutes daily. If the disease be acute and _infectious_, use the A C current some four to six times, and then change to A D. Apply the current as directed above. If the disease be chronic, or the lids granulated, treat with A D, _very mild_ current, applying the eye-bath, N. P., to the eyes, and place the P. P. upon the spine, at the top of the back. Treat each eye three to five minutes three times a week. In cases of simple inflammation, (not infectious), and that chiefly or entirely in the lids, it is often quite as well or better to treat over the closed lids with the finger, holding the sponge-roll P. P. in the same hand. AMAUROSIS. (_Paralysis of the optic nerve._) Use B D current, moderate force, three or four times, and then change to C D. Apply the eye-bath, N. P., to the eye, and sponge-cup P. P. upon one of the upper dorsal vertebræ. Treat three to five minutes on each eye, three times a week. STRABISMUS. (_Discordance of the eyes._) If neither of the _rectus_ muscles have been cut and cicatrized, and if the deformity be not congenital, it may ordinarily be cured. Take B D current, with small pointed electrodes. If the eye be turned _inward_, insert P. P. in the outer angle of the eye, so as to bear upon the _rectus externus_, and N. P. in the inner angle, so as to bear on the _rectus internus_. Let the current be of what force the patient can bear. Withdraw the electrodes frequently, to rest the eye, and then reapply them. Apply the current in this manner six to ten or twelve times at a sitting. The eye will soon become inflamed, but the inflammation will quickly go down. Treat daily, or on alternate days, as the eye can bear. After treating some ten or twelve times, if the organ does not come into place let it rest a week, and then resume the treatment as before. If the eye be turned _outward_, treat in the same manner as directed above, except that in this case, the P. P. must be inserted in the _inner_ and the N. P. in the _outer_ angle. CATARRH. (_Acute._)
