V. OF THE TREATMENT OF SCARLET FEVER. Little modification is required in the treatment of scarlet fever. The most important difference between continued fever without and with an eruption, is the greater predominance of nervous affection in the former and of inflammatory affection in the latter. Accordingly, in scarlatina there is not only a greater tendency to inflammation than in ordinary fever, but the inflammation which is set up in the febrile circle of organs approximates more to the character of pure inflammation. There is greater vascular action, with less nervous and sensorial depression. The consequence is, that blood-letting may be carried to a greater extent, and will be attended with still more decided and more certain efficacy than in ordinary fever. After a decided impression has been made upon the vascular excitement by general bleeding, the application of ten or twelve leeches to the throat is of sovereign efficacy. If scarlatina be treated in this manner on the second day, or sometimes even on the third, though it commence with exceedingly severe symptoms, yet the patient will be convalescent in the course of three or four days. It is not probable that much advantage would be derived from the detail of numerous cases to illustrate the modification of treatment, and the circumstances under which particular remedies should be chosen. A few are subjoined as specimens of the ordinary extent to which bleeding may be carried, and of the usual conditions under which wine may be exhibited, and of the results, when favourable, produced by each remedy.
