The eyes are subject to various disorders, but the extreme delicacy of the organ renders it highly important that as a general thing they should be treated by a careful and scientific physician or occulist. The step from sight to blindness is so short, that often the utmost care and caution are neccessary to ward off serious consequences. Examine particularly the article on the eye in the chapter on Anatomy.

Lotions should as a general thing be avoided, confining external applications to pure soft water, milk and water, or a mixture made from pouring water upon quince seeds. These applications may be made either cold or tepid, according to the feeling of the patient. If the redness is occasioned by external injury, or is slight and the result of a simple cold, six drops of Arnica may be placed in a cup half full of water, and the eye washed with it three or four times a day.
