2645. LUMBAGO.—A "new and successful mode" of treating lumbago, advocated by Dr. Day, is a form of counter-irritation, said to have been introduced into this country by the late Sir Anthony Carlisle, and which consists in the instantaneous application of a flat iron button, gently heated in a spirit-lamp, to the skin. Dr. Corrigan published, about three years ago, an account of some cases very successfully treated by nearly similar means. Dr. Corrigan's plan was, however, to touch the surface of the part affected, at intervals of half an inch, as lightly and rapidly as possible. Dr. Day has found greater advantages to result from drawing the flat surface of the heated button lightly over the affected part, so as to act on a greater extent of surface. The doctor speaks so enthusiastically of the benefit to be derived from this practice, that it is evidently highly deserving attention.

2646. PALPITATION OF THE HEART.—Where palpitation occurs as symptomatic of indigestion, the treatment must be directed to remedy that disorder; when it is consequent on a plethoric state, purgatives will be effectual. In this case the patient should abstain from every kind of diet likely to produce a plethoric condition of body. Animal food and fermented liquor must be particularly avoided. Too much indulgence in sleep will also prove injurious. When the attacks arise from nervous irritability, the excitement must be allayed by change of air and a tonic diet. Should the palpitation originate from organic derangement, it must be, of course, beyond domestic management. Luxurious living, indolence, and tight-lacing often produce this affection: such cases are to be conquered with a little resolution.
