AVOIDING SHORTSIGHTEDNESS. Shortsightedness is rapidly on the increase. The' great cause of this deterioration is not so much due to overwork as to straining of the eyes by working ox reading in deficient light. When the light is poor we unconsciously bring our eyes and the object on which they are focussed nearer together. This means that all the fine focussing mechanism of the eye is working under an unnecessary strain. A plentiful supply of light is not all that is required; it should strike evenly on the object at which one is looking, and should fall on the worker's head from a height. When . the light comes from above, the> eyebrows and upper lashee prevent any direct rays falling on the unprotected eyes. ' When the source of light is on the level with or below that of the eyes, the more scanty lower lashes do not afford adequate protection. Let the light, if possible, come from behind,' over one shoulder, so that when the eyes are unconsciously raised, as they are from time to time, they will not meet any perceptible change in the mr tensity of the light. Avoid working by the light of French windows. The l-ays coming through'the lower part of such windows, and striking the unprotected . eyes :in an upward direction, are common causes of eyestrain. ANAEMIA. Theoretically the anaemic person should be. pale and white-cheeked. In practice, this is not always the case. So often a-person will allow himself to reach an advanced stage of anaemia without suspecting the true nature of his illness. When a hard-working town-dweller of sedentary habits •is continuously tired and in unexplained ill-health, it is very frequently due to an abnormal condition of the blood, and even a rosy complexion is not altogether inconsistent with this. There -are two main varieties of anaemia; in the one the'quality of the blood cells is poor, while their number is still practically normal; in the other,; the individual cells are of fair quality, ! but are greatly reduced in number. : The first variety is found almost with-' out exception in women and giris, arid gives them a greenish hue of complexion easily recognised. ■ The causes of anaemia are manifold: ■any departure from the ordinary laws of hygiene may. be sufficient. ' ■ '. Iron in some form is the standard; treatment.. Iron pills should- not be taken indiscriminately, for certain forms of: iron are not able to be absorbed by some systems, and do more harm than good. An abundance of fresh air and sunlight will in most-cases do more towards a speedy cure than ajiy amount of'drugs. ..'..-' . TREATMENT OiF CHILBLAINS. In our last issue (says "Science Siftings") we" mentioned the great utility of calcium chloride for 'chilblains'. Now, we find Dr. E. Mansel Sympsqn advising peroxide Of hydrogen. He has frequently, employed it, and has been greatly pleased by its almost unvarying success. His plan is.; for the patient to bathe thej affected parts in peroxide of hydrogen. .(10 vol.' strength), diluted with equal parts of previously boiled water, still hot, for fifteen or twenty minutes, .twice daily. This treatment has the ■additional advantage of being' capable?'pt carried' out even if the chilblains are cracked and- ulcerated, though, it is-well to diminish -the.strength of the peroxide if much. pain and; irritation is- produced by the application. A. continuation of this treatment for two 'or three days in indst Cases will effect:* cure.
