=Diphtheria.=--Diphtheria is a malignant and very infectious disease. It may often be communicated by a kiss, a touch of the hand, or by drinking out of the same cup with the sick person. The mildest case should be carefully isolated. In the family this may sometimes be done by removing the patient to an upper room, which can be well ventilated by means of windows and an open fire. The contagion of diphtheria is not carried far by the atmosphere; hence, by strict attention to cleanliness and ventilation, it may be quite possible to isolate a case even under the family roof. The disease is characterized by soreness of the throat, pain in swallowing, apoplectic, epileptic, hysterical, or the result of poisoning. Put a cork between the patient's teeth, that the tongue may not be bitten. Loosen the clothing, have plenty of fresh air, and do not restrain the movements of the patient, except to prevent injury or bruising. Rub the temples with cologne or spirits, and, as soon as the patient can swallow, give a little cold brandy and water. Dr. W. A. Scott, of Iowa, where, in the latter part of 1889, diphtheria raged, found a valuable and effective remedy for this dread disease. The recipe can be filled at any drug store, and used by any person without danger:-- Take ten grains of permanganate of potassium and mix with one ounce of cold water. As soon as dissolved, it must be applied with a rag or sponge mop or swab to the whitish places in the tonsils, and other parts that have the diphtheria membrane on them. Do this very gently, but thoroughly, every three hours until better; then every six hours until well. It does not give pain, but is rather nauseous to the taste. If the tongue is coated white, mix one drachm of hyposulphite of soda and five drops oil of sassafras in four ounces of syrup made of sugar and hot water, and give a teaspoonful every 1 to 3 hours, as needed, when awake. If the tongue is not coated white, I mix 20 drops of tincture of phytolacca in four ounces of cold water and give a teaspoonful every 1 to 3 hours, as needed, when awake. (The phytolacca is the common poke-root of the South, and as it loses its strength by drying and age, the tincture should be from the fresh root, or it is worthless.) It is well to apply a little sweet-oil or cosmoline to the outside of the throat to protect from the action of the air, as the patient must be protected from all danger of getting chilled. In the beginning of the disease, in mild cases, the above solution of permanganate of potassium is all I use, and all that is needed, as the disease is local at first, but rapidly affects the whole system when seated. In the stinking form of diphtheria this solution soon destroys all smell, and in every case destroys the diphtheria membrane without leaving any bad effect.
