We must think of not merely relieving, but of curing the patient, by attacking the poisonous substance where it has lodged in the nerve centres of the bowels. Pure water, with just as much acetic acid or vinegar dropped into it as will make it taste the least sour, should be given in tablespoonfuls (and hot) as frequently as the patient can take it without discomfort. If possible it should be distilled water, or rain water filtered, but certainly as pure and soft as can be procured. There is no drug that can be prescribed that is equal to pure water, and no acid better than common white vinegar. These three things--the strong fomentation of the feet and legs, the cooling of the head, and the dissolution of the poisonous substances by means of pure water, and their counteraction by means of acid in very small strength--will do wonders in gastric fever. The "turn" may be secured in a week instead of three, if these things are skilfully and persistently applied. We should say that the strong fomentation and cooling of the head should not be done oftener than twice a day, and only once if the patient feels too weak for twice. But as a general rule, the person who is ill will wish these things at least twice a day. The sips of water should be given, say in a dozen separate tablespoonfuls at a time, at least thrice a day--oftener if desired by the patient. For food there is nothing equal to good fresh buttermilk. All alcoholic drinks are damaging in a high degree in such an illness as this. Sweet milk, if somewhat diluted with good water, will do, but there is nothing so good as the buttermilk fresh from the churn. Absolute rest in bed is necessary, and no solid food should be given to the patient until his temperature has been ten days at normal point. All food given in the illness should be liquid enough to pass through the meshes of a milk strainer. Care should be taken in this matter, as death has often followed the taking of solid food, when otherwise recovery would have come. Milk should always form the largest portion of the diet, and may be given with arrowroot or oatflour. Beef tea is of little use, and is always to be avoided if there is a tendency to diarrhoea. Plenty of cold water may always be given.
