Having arrived at the knowledge of what disease is, its cause, the indications necessary to be accomplished, and the means to be used to accomplish those indications, we have now to point out the particular circumstances or symptoms requiring the accomplishment of each of these indications, and the mode of applying the remedy. This we shall endeavor to do in a manner so plain and simple, that any person may not be at a loss to know what course to pursue in any form of disease.

A large proportion of the different forms of disease depends on constriction or spasm, either general or local, producing an obstruction of the secretions, and a retention of the morbific impurities of the system. The cause is cold, or any irritating substance applied to, or taken into the system. The result is local or general excitement, usually termed fever or inflammation. Other forms of disease depend on relaxation, paralysis, injuries, or change in structure of some organ. Notwithstanding the general adaptedness of "a course of medicine," as described in this work, for the cure of every form of disease, yet some of the different manifestations of disease may require a modification of the treatment, so as to accomplish the object sooner and with less suffering and inconvenience to the patient; we shall therefore give a particular description of such forms of disease and their symptoms and peculiar treatment.
