TREATMENT.--In all children of distinctly nervous type and especially those of nervous parents, the first essential duty is to develop their muscular system. Try in every way to make healthy animals of them. Attention and treatment should not be directed toward the nervous system. If the child is made strong by out-door life, good plain, digestible food, early hours, regular sleep in thoroughly aired rooms, regular bathing, and if the school work is conducted with moderation and judgment, the nerves and the nervous temperament will participate in the healthy growth which will follow as a result. Tea and coffee should be forbidden. Exciting books and questionable entertainment as given in picture shows and theaters must not be allowed. If older members of the family, or parents, are excitable and nervous the children should be sent away to the country from them. They should be put in charge of a person who will exercise firm control over them. It may be necessary to take these patients away from other children, and isolate them under proper control until they are able to control themselves. They should be interested in exercise that compels them to work; they should live and if convenient sleep out of doors; and they should take iron or cod liver oil, or any other indicated tonic. If they complain of pain they should receive cold-water douches, or the cold pack, or the shower bath; and they should be put to bed and treated firmly but kindly. Attention to the bowels is always essential, because these children are as a rule the victims of chronic constipation. WHAT A MOTHER SHOULD KNOW ABOUT CATHARTICS AND HOW TO GIVE A CHILD A DOSE OF CASTOR OIL.--Broadly speaking there are three kinds of cathartics. I will, in a simple way, explain their action so that a mother may know which one to select under certain circumstances. Frequently a mother is told by her physician to "keep the bowels of her child open." Few mothers know how to keep the bowels open, and as this is an important matter, every mother should know the reason why "any" laxative or cathartic is not always suitable. CASTOR OIL.--This is one of the oldest and one of the best cathartics we possess for children. It is a mechanical cathartic; it acts in exactly the same way as a street-cleaning machine. It cleans the street by sweeping or pushing everything before it. CALOMEL--This is a chemical cathartic. It acts through the blood. When it is absorbed by the blood its chemical ingredients act on certain nerves as irritants. These nerves excite the liver and bowel to action and an evacuation is the result. CITRATE OF MAGNESIA.--This is a saline laxative. It acts by drawing out of the bowel wall enough liquid from the blood to sweep the contents out. It may be likened to the street cleaner who flushes and cleans the street by means of a hose pipe attached to the water hydrant.
