If one finds himself rubbing his eyes, it is a clear sign that they are irritated. It may be time to stop reading. At any rate, one should find the cause, and not proceed with the work until the irritation ceases. If any foreign object gets into the eye, as a cinder, it is better not to rub the eye, but to draw the lid away from the eyeball and wink repeatedly; the increased flow of tears may dissolve and wash the matter out. If you must rub, rub the other eye. If it be a sharp-cornered cinder, rubbing may merely serve to fix it more firmly in the cornea or the mucous membrane of the inner surface of the eyelid. If it does not soon come out, the lid may be rolled over a pencil, taking hold of the lashes or the edge of the lid. The point of a blunt lead pencil is a convenient and safe instrument with which to remove the particle. Sometimes being out in the wind (especially if unused to it), together with bright sunlight, may irritate the eyes. If after such exposure one finds lamplight irritating, he will do well to go to bed early, or to remain in a dark room.
Be careful to keep the eyes clean. Do not rub the eyes with the fingers. Aside from considerations of etiquette, there is danger of introducing foreign matter that may be harmful. It is very desirable that each person have his individual face towel. By not observing this rule, certain contagious diseases of the eye often spread rapidly.
If there is any continuous trouble with the eyes, consult a reliable oculist. Many persons injure the eyes by not wearing suitable glasses. On the other hand, do not buy glasses of peddlers or of any but reliable specialists. One may ruin the eyes by wearing glasses when they are not needed. Sight is priceless.
THE PROGRESS OF MEDICINE IN THE NINETEENTH CENTURY

The word “medicine,” as used in the title of this paper, includes all branches of the art of prevention and treatment of disease and injuries; all discoveries of methods of diminishing physical pain and of prolonging life, and also that part of modern science which is concerned with accurate knowledge of the structure and functions, normal and abnormal, of the human body, and of the causes of diseases. In other words, it includes not only therapeutics, medical and surgical, but also physiology, pathology, and hygiene.
In all these branches of medicine greater progress has been made during the last century than had been made during the previous two thousand years. This progress has been largely due to improvements in methods of investigation and diagnosis, resulting from increase of knowledge in chemistry and physics; to better microscopes and new instruments of precision; to experimental work in laboratories and to the application of scientific method and system in the observation and recording of cases of disease and of the results of different modes of treatment. The introduction of statistical methods in the study of cases of disease and of causes of death; the discovery of general anæsthetics; the adoption of antiseptic [excluding microbes] and aseptic [uninfective] methods in surgery, and the development of modern bacteriology—each marks a point in the history of medicine in the nineteenth century.
