which has previously been thoroughly aired. While he is in this room the sick room should be as thoroughly aired as is possible. Keep this plan up all through the disease; change the position of the patient in bed every two hours. He should never be allowed to lie on his back for hours at a time. In this way the different parts of the lungs get a chance to air themselves,—the air cells expand and the oxygen in the air and the fresh blood tend to heal the parts more quickly.

It would be distinctly wrong to go into the detailed symptomatic treatment of broncho-pneumonia in a book of this character. Inasmuch as this is one of the most serious diseases of infancy, no mother should attempt to treat it alone. A physician is absolutely necessary and the most the mother can hope to do is to follow out his directions to the letter.

He may direct the use of mustard pastes but it is essential to know where to apply them. If he should request the use of the cotton jacket, the height and character of the fever must regulate its use. Stimulants are always necessary, whisky and strychnine being given in every case, but if given at the wrong time they may do more harm than good. Cough mixtures may be necessary, but frequently they are contra-indicated. Drugs and cold sponging may be used to reduce the fever, but they are dangerous if used when conditions do not justify their use. Complications must be diagnosed when they occur, and the correct methods of treatment promptly instituted. A competent physician alone can assume the responsibility of these various phases of the disease.

Every mother should appreciate, however, that pneumonia is frequently the result of carelessness. It is a well-known fact that pneumonia is an infrequent disease among children of the well-to-do, because the hygienic surroundings of these children are better and because they receive competent attention if suffering with colds and bronchitis. Bronchitis is quite common in all classes of children, but in the lower walks of life it is the custom to allow children to run around while they give every sign of having a heavy cold, and a beginning bronchitis. These children should receive treatment and should be kept indoors and in bed if they have even a slight fever, as pneumonia is frequently the inevitable outcome. They should be carefully fed, and all signs of stomach or intestinal troubles attended to at once.
