The old school boast that their whole system of blood-letting, purging, and poisoning is based on _enlightened experience_! yet their victims have often discovered, by dear-bought "experience," (_many of whom are now doing penance with ulcerated gums, rotten teeth, and foetid breath_,) that, however valuable this "experience" may be to the M. D.'s, they, the recipients, have not derived that benefit which they were led to expect would accrue to them. From what has already been written in this work, the reader, provided he divests himself of all prejudice, will perceive that allopathic experience is not to be trusted, for their principles are false; hence their experience is also false. Professor Curtis, to whom we are indebted for much valuable information, says, "Do not the old school argue that the most destructive agents in nature may be made to '_aid the vital forces in the removal of disease_ by the judicious application of them'? Does not Professor Harrison say, that the lancet is the great anti-inflammatory agent of the _materia medica_, that opium is the _magnum Dei donum_ (the great gift of God) for the relief of pain, and that mercury is the great regulator of all the secretions?" Anatomy and physiology are now being taught in our public schools. The people will, ere long, constitute themselves umpires to decide when doctors disagree. We apprehend it will then be hard work to convince the intelligent and thinking part of the community that poisons and the lancet are sanative agents.
