During the first stages of this disorder, the patient should breathe an equal temperature, as nearly as it can be managed, not too warm and close, but equal; and when the virulence of the disorder _has passed away_, the open air (if the weather be mild) may be frequently resorted to; and a change of air, where it is practicable, will often remove at once all remains of the complaint. The only thing that remains to be mentioned, is the proper diet, which is, indeed, of paramount importance; and for children of even six and seven years of age, ought to be little more than milk and broths. These are nourishing, and more readily digested than meats or puddings. One prevalent error is, that milk engenders phlegm; but this is a mistake. Should the milk be found to curdle on the stomach, a little common salt must be added; or, better still, use asses’ milk, if it is attainable. These light nutriments quickly pass out of the stomach, or if brought out by coughing twenty times during the day (which is sometimes the case), the child will immediately take more with avidity. If thirst prevails, a little toast-and-water may be given. When taken in time, and treated properly, hooping-cough is scarcely ever fatal, indeed never, as long as the patient is free from fever, or other disease. If the attack, from its length and severity, should cause a loss of strength, health will soon be recruited by a cold infusion of bark, gentle exercise, and pure uninfected air, and dieted with a nourishing broth, made as follows:— Take three-quarters of a pound of veal, the same quantity of beef, chopped very fine, and simmered for three hours in about two quarts of water. Strain it, and let the invalid drink the clear liquid, hot or cold, as may be most agreeable. _Mixture for Hooping-Cough._ Ipecacuanha Wine 2 drachms. Carbonate of Soda ½ drachm. Paregoric Elixir 2 drachms. Water 1 ounce. A tea-spoonful or two (according to the age of the patient) may be given three times a day. TEETHING.
