There is still one syringing which we may notice--that of suppurating ears. If an ear is discharging from some internal sore, nothing is more important than syringing with acetic acid, but it must be done with very peculiar care. The water used should be as nearly as possible of exact blood heat, and the acetic acid of the exact strength at which it will give a fine comfortable feeling in the ear. It must neither feel as if it were a mere wetting of the ear, nor that it gives the least pain. The syringe, too, must be used gently, so as not to force the water strongly against the internal parts that are so tender. It is a soaking operation rather than a forcible urging of the water into the ear which is wanted. If this is nicely done, say twice a day, the acid will reach the sore, and we may confidently look for a cure. Even when the bones are wasting, as we have seen in the case of the upper jaw, if this acid can be really brought to bear upon the sore, it will be cleansed and healed. In this simple way we have seen many, both old and young, delivered from sore trial, and made to enjoy life and health again. PHYSICAL CULTURE. Much weakness might be prevented and often cured by light gymnastic exercises practised twice a day, say on rising and at bedtime, giving tone to the muscles and bringing into regular use many which in ordinary daily life are seldom or never used. The various vital organs of the body owe much of their health to the proper exercise of the surrounding muscles; it will be seen then how necessary a system of regular exercise must be. The best way to learn this is to take a course of Swedish Drill or other good system at one of the gymnasiums which are now so common in Britain and America. But as many of our readers live in places where such cannot be had, we shall try to indicate by diagrams some simple movements which can be practised by anyone. A few general rules should be borne in mind:-- Begin with a short time, say five minutes; omit at first the more fatiguing movements and gradually increase as the strength improves. The time spent need never be long; fifteen or twenty minutes is long enough at any one time. Do the movements slowly and deliberately, stretching the muscles to their full extent. Fix your mind on the particular limb that is being exercised. Practice in a room with open window, with little clothes on, or with none; a daily air-bath is very conducive to health. Each exercise need not be performed more than three times, until strength is fairly great. Never go on with the exercises so long as to be more than just a little tired. It is a good plan to write out the exercises clearly on a good-sized card or sheet of stiff paper, which can be set where it will be easily seen while one is exercising.
