The bedrooms of children suffering from whooping-cough should be large and thoroughly aired day and night. The nourishment in these cases is of great importance. They should be carefully fed, and if they vomit with the paroxysms of coughing, they should be fed small quantities frequently. Any form of digestive disturbance is very apt to accentuate the frequency of coughing. A fluid diet of milk is the best. Milk punches aid in keeping up the strength; malted milk and eggs beaten in milk are nutritious and easily digested. So far as internal medication is concerned, I have found pertussin to be the most efficacious remedy. If it is begun early and in sufficient dosage, it not only favors an early termination of the disease, but it lessens the frequency and the severity of the paroxysms. If it is suspected that the child has been exposed to whooping-cough, pertussin may be given during the catarrhal stage with the advantage that it will render the whole course of the disease milder. If it is given during the course of an ordinary catarrhal cold, it will in most cases be as effectual as any ordinary cough remedy. The dosage should be large enough to produce results. I have found a teaspoonful every two hours to a child of three years to be the average dose. In older children I give two teaspoonfuls every three hours. It is necessary to continue its use throughout the disease. The taste of pertussin is pleasant and young children take it willingly. When the disease is inclined to a protracted course, or when the cough does not subside, especially during unfavorable weather, it is of great importance to send the child away. A change of climate, preferably to the seashore, even for a short time, will act like a charm, and will cure the cough of whooping-cough quicker than any other possible measure. MEASLES Measles is the most widely prevalent, eruptive, contagious disease. With few exceptions, every human being "gets" measles. As an uncomplicated disease it is never fatal, and is not even regarded as dangerous. Because of this characteristic, however, parents are neglectful and complications occur, and these frequently prove fatal. One attack renders the patient immune. It is very highly contagious and spreads with great rapidity among those who have never had it. It is not possible to carry the disease any great distance by a third person or by means of living objects. It does not, however, cling to clothing or other objects as long as scarlet fever. Its period of incubation is from eleven to fourteen days.
