His pharmacopeia consisted not in poisonous pills and potions but in plenty of exercise, fresh mountain air, water treatments in the cool, sparkling brooks, and simple, wholesome country fare, consisting largely of black bread, vegetables, and milk fresh from cows fed on nutritious mountain grasses. The results accomplished by these simple means were wonderful. Before he died, a large sanitarium, filled with patients from all over the world and from all stations of life, had grown up around his forest home. Among those who made the pilgrimage to Grafenberg to become patients and students of this genial healer, the simple-minded farmer-physician, were wealthy merchants, princes and doctors from all parts of the world. Rapidly the idea of drugless healing spread over Germany and over the civilized world. In the Fatherland, Hahn the apothecary, Kuhne the weaver, Rikli the manufacturer, Father Kneipp the priest, Lahmann the doctor, and Turnvater Jahn, the founder of physical culture, became enthusiastic pupils and followers of Priessnitz. Each one of these men enlarged and enriched some special field of the great realm of natural healing. Some elaborated the water cure and natural dietetics, others invented various systems of manipulative treatment, earth, air and light cures, magnetic healing, mental therapeutics, curative gymnastics, etc., etc. Von Peckzely added the Diagnosis from the Eye, which reveals not only the innermost secrets of the human organism, but also Nature's ways and means of cure, and the changes for better or for worse continually occurring in the body. In this country, Dr. Trall of New York, Dr. Jackson of Danville, Dr. Kellogg of Battle Creek, and others caught the infection and crossed the ocean to become students of Priessnitz. The achievements of these men in their respective fields of endeavor will stand as enduring monuments to the eternal truths revealed by the genius of Nature Cure. Quimby, the itinerant spiritualist and healer, became successful and renowned by the application of the natural methods of cure. At first his favorite methods were water, massage, magnetic and mental treatment. Gradually he concentrated his efforts on metaphysical methods of cure, and before he died, he evolved a complete system of magnetic and mental therapeutics. Quimby's teachings and methods were adopted by Mrs. Eddy, his most enthusiastic pupil, and by her elaborated into Christian Science, the latest and most successful of modern mental-healing cults.
