Everything must be kept clean around the patient, and a vessel must be provided, containing a little chloride of lime into which he spits or hawks the phlegm from his throat. The membrane or slough in the throat or nose must be thoroughly disinfected and the only evidence that this has been successfully accomplished is when all offensive odor has disappeared. For this purpose as a local application I employ the following preparation: Solution of subsulphate of iron (Monsel’s solution) 3 drams, glycerine 5 drams; mix and pour ten to twenty drops into a saucer and by means of a camel’s hair brush apply to the diphtheritic membrane until the character and odor of it is destroyed; this application repeat every four hours. Should the nasal passages be also affected mix a teaspoonful of the preparation to a teacupful of warm water and by means of a syringe wash the nasal passages out several times a day. Give the patient internal medicine to disinfect the stomach and for its alterative action on the blood: for this purpose use tincture of iron 4 drams, simple syrup, add to make 4 ounces. To a child seven to ten years old give a teaspoonful, ten or fifteen minutes each time, after the brushing. Between the times of brushing and giving the medicine, that is two hours afterwards, give the nourishment and stimulant; this consists of milk punch. A child seven to ten years old should take no less than a tablespoonful of whisky, with or without a little sugar, in a half to a teacupful of milk beaten thoroughly together with an egg beater; this is to be taken for a meal and drank at once, and repeated every four hours. No other food or nourishment must be given for a number of days, and if the child is thirsty between times allow it to drink sweetened water and whisky. Sometimes the glands of the neck and the tonsils swell and become very painful; for this the Belladonna ointment applied with gentle friction night and morning and the neck enveloped in cotton batting are certain to give relief. The efficiency of this treatment depends upon the intelligence and faithfulness with which it is used.
