Mix, and take one table-spoonful three times a day. When the joint will bear friction, the flesh-brush should be used daily, a milk and vegetable diet pursued, exercise and change of air adopted, and, where possible, the bath or chalybeate waters moderately taken. The gouty deposits or concretions formed in joints of persons afflicted with gout, or chalk stones, as they are commonly called, consisting of an insoluble _urate of soda_, can only be dissipated in one way, by the steady use of benzoic acid, which, in doses of one scruple combined with two drachms of the carbonate of potass, is to be taken dissolved in water every day an hour after breakfast and dinner, and continued till the depositions are absorbed. RHEUMATISM. A very painful disease which affects the muscles and joints of the human body, chiefly the larger joints and most important muscles, as those of and around the shoulder, hip, knees, and back. Rheumatism is divided into acute and chronic; or that condition, when the disease is in vigour and freshness attended with extreme pain, and more or less of general fever, and that state, when the system, by long acquaintance with the disease, has become familiar to its attack, and it comes on from any trifling exposure to cold, and after affecting a larger or smaller surface, declines of its own accord—all the symptoms however, being materially lighter than in the acute state. Besides being acute and chronic, rheumatism is very often both general and local, and this, under both previous conditions, and the diseases known as lumbago and sciatica, are merely forms of acute or chronic _local_ rheumatism.
