The fever is high in the sudden cases and lower in the cases of gradual onset. The prostration is more severe when the onset is sudden and in infants may be very marked. The termination of the disease depends upon the cause, the treatment, and the previous health of the child. In healthy children promptly and properly treated it may be all over in a week. In delicate, poorly nourished children, and especially in the summer time, it may be the beginning of trouble that may eventuate in death. Treatment.--There is no condition in the whole realm of diseases of childhood where the knowledge of the mother may have such important results as this condition. The most effective time to treat these cases of intestinal indigestion is before the physician is called. There are few diseases in which time is so valuable, so far as final results are concerned, as it is here. Every mother should know the significance of a loose, green stool. She should be taught that it means danger and consequently demands prompt treatment. The first indication is to empty, thoroughly, the bowel. The best means for this purpose, if it is immediately procurable, is calomel. If calomel is not procurable at once give castor oil, two teaspoonfuls to an infant, one tablespoonful to an older child. Calomel should be given in one-eighth-grain doses, repeated every three-quarters of an hour for eight or twelve doses, until the bowel is thoroughly cleaned out. Don't be afraid of a few extra movements at the beginning. Better clean out thoroughly at the start than to be compelled to do it all over again after the child is weak and suffering from the poison of the disease. The next important thing to do is to stop milk at once. The thirst is usually intense and if vomiting is not present it can be moderately relieved by giving small quantities frequently of cool boiled water or mineral water or strained albumen or barley water. We quite often have to stop all food and liquids by the mouth for twenty-four hours. If the prostration is very great and the child looks as though it might collapse, it can be given brandy in cracked ice from time to time. After the bowels have been thoroughly cleaned out, never before, some medicinal agent may be given to stop the unnecessary diarrhea. In a very large number of promptly and properly treated cases this is not needed. If it is thought best to use it the physician will select the agent according to the conditions present and prescribe it.
