Cases are not unfrequently presented of _inflammatory action_, more especially where it is internal--traumatic cases and others--which the practitioner finds it impossible to subdue with medicine. But, with a proper knowledge of the system herein taught, he has at his command a power with which he can control such cases with almost infallible certainty, provided he can get access to them within reasonable time. The same may be said of fevers, particularly those occasioned by miasmatic or infectious virus. These are often difficult to manage by the use of medicine, and not seldom prove fatal, in spite of the best talent and skill which the profession can afford. But the electric current, rightly selected and scientifically applied, destroys or neutralizes the virus and restores the normal polarization, and so effects a cure. _Neuralgic affections_ are frequently found difficult, or even impossible, to be cured by means of medicines, and yet, in the very same cases, these affections yield and disappear with comparative facility when brought under the electric current, judiciously applied, according to the principles of this new system. _Chronic cases, and others of an asthenic character_, are often very stubborn under the medicines of pharmacy, and are commonly the dread of physicians; yet, under scientific treatment by electricity, they rarely fail to lose their formidable character and to become obedient to the remedial agent. _Fourth._--In enumerating a few of the peculiar advantages of this system, I should add that it corrects the usual _electric_ practice of the profession, so far as they become acquainted with it. As before intimated, the mass of physicians at present, who treat more or less electrically, do so with no knowledge, or next to none, of the great _versatility_ of action of which the electric current is capable. They know nothing of the electrical polarization of the living organism in health, nor how it is variously affected in disease. The particular _electrical_ state of the diseased organs is a matter foreign to their minds. They appear to suppose the point to be immediately aimed at as a means of cure is to get the electricity from the machine into the affected part or parts; whereas it should be to change, by correction, the _polarization_ of the part or parts; and, if there be virus present, to neutralize that. Equally unacquainted are they generally with the diverse physiological action of the several modifications of the electric force--galvanism, magnetism, faradism, and frictional electricity. This, in their candor, they commonly acknowledge. And, for the most part, they are little or nothing better acquainted with the _distinctive_ effects on the system of the positive and negative poles of the instrument. There is, therefore, plainly no _science_ in their electrical practice. Every thing is done at random--all is empirical.
