1. The common continued fever of this country, in its mildest form, requires little or no treatment. There is no affection of any organ intense enough to need the application of a powerful remedy. All the organs which constitute the febrile circle are deranged in their functions, but that derangement is so slight that a cure takes place spontaneously in the course of a few days. Confinement to the bed; the abstraction of stimuli; fever diet; a calomel purgative at night, consisting of one or two grains of calomel with six or ten of rhubarb, followed in the morning with half an ounce of castor oil; and these remedies repeated every day, or every alternate day, constitute the whole treatment which is required. 2. Whenever the fever passes beyond this, its mildest form, it becomes a serious disease. It is never for a moment to be trifled with; never for a moment to be neglected. Because it is moderate in the commencement, it is not to be presumed that it will continue moderate through its subsequent course: it may become most formidable; if the proper remedies are not applied early and vigorously, it generally does become truly alarming; the train only is apparent; the mine is concealed; the only safety for the patient is to prevent the train from being kindled; if that be once kindled, it may be no longer possible to save the patient from destruction. When the mildest case of fever passes to a severer form, what is the event that happens? What is the change that takes place in the organs? The preceding pathology will, indeed, have been written in vain, if there can now be any doubt in the mind of the reader on that point. The great value of the facts there disclosed is, that they teach us what happens in organs which we cannot see, and declare to us by the external signs or symptoms, the internal actions that are going on. Out of the hundred cases which have now been recorded, and the history of which has been made known from its commencement to its termination, take any one, or fix upon any number, in which the symptoms from being slight became moderate, and from moderate severe, or, in which the symptoms were severe from the beginning, what is found after death? Inflammation, in general, rising in degree, and increasing in extent, or both, in proportion to the intensity of the febrile affection. If this, which may be justly considered as the law of the disease, be not absolutely constant and uniform, it may be safely affirmed, at least, that there are as few apparent exceptions to it, as to any general law that can be named.
