Pleurisy.--The pleura is the tender double web, or membrane, which lines the inside of the chest on the one side and covers the lung, or rather encloses the lung with its other fold. Each of the two lungs has its pleura in which it works, and each side of the chest is lined by one side of this sensitive organ. The slender lining passes round the greater part of one whole side of the body with one-fold, and round the whole of the lung with the other. Let us suppose (which often takes place) that the front of the body is defended with what is called a "chest protector," but the sides and back are exposed to a chilling atmosphere. Part of the pleura, and that part which is farthest from the surface, is sheltered, but the greater part of it, and that nearest the surface, has no such protection. In the case especially of women this is the state of things. It seems as if people thought that they only need to keep a few inches of the breast warm--that is keeping the chest all right--though the sides just under the arms, and the back under the shoulder-blades, are of far greater importance. The throat is even muffled, and a "respirator" worn, so that fresh air is not allowed to get inside the lungs, while the pleura is exposed to chill at the back. The consequence of this is that vital action is so abstracted from the pleura that the tension of its small vessels is relaxed, and blood is admitted as it is not intended it should be. Severe pain is felt on one or both sides, and round under the shoulder-blade. A painful cough arises, and great fever is produced. In such a case the treatment is on the same principle as that given in Lungs, Inflammation of the, which should be read. The inflamed part must be cooled by applying towels well wrung out of cold water round the side, applying a fresh one when that on the part becomes warm. If the pain does not leave in half-an-hour of this treatment, or if the patient be weak to begin with, or if any chilliness is felt, pack the feet and legs in a large hot fomentation. The cooling of the side may then go on safely until a curative effect is produced. We may not be able to give the theory of action of this treatment, but we know that in many cases it has perfectly and very speedily been successful, and that it leaves no bad results, as blistering and drugging are apt to do. We know of one case in which it took twenty-four hours' constant treatment to effect a cure. But it did effect it. Two friends took "shifts," and saw that all was thoroughly done. This will give an idea of the proper way to go about the matter. Poisoning.--The following are the antidotes and remedies for some of the more common forms of poisoning. Alcohol.--The patient is quite helpless, and there is usually a strong smell of alcohol. If the patient is intoxicated at the time give an emetic. If there is evident prostration from a long bout, keep him quiet and warm. Hot tea not too strong may be given.
