And so Dr. FitzGerald is to give us specific details of one of the most wonderful and perplexing things connected with the art of medicine. This, because a physician’s premise is to teach--as well as heal. Because publicity concerning the prevention and cure of disease is a duty he owes mankind: not as an altruist, but as a human being. Edwin F. Bowers, M. D. Sept. 1, 1916. PUBLISHERS’ NOTE. The chapters comprising this book were first published as special articles in the “Associated Sunday Magazines”, and “Every Week”. Accompanying the introductory article was this comment by Mr. Bruce Barton, the able and critical editor of these Magazines. It explains itself: “For almost a year Dr. Bowers has been urging me to publish this article on Dr. FitzGerald’s remarkable system of healing, known as zone therapy. Frankly, I could not believe what was claimed for zone therapy, nor did I think that we could get magazine readers to believe it. Finally, a few months ago, I went to Hartford unannounced, and spent a day in Dr. FitzGerald’s offices. I saw patients who had been cured of goiter; I saw throat and ear troubles immediately relieved by zone therapy; I saw a nasal operation performed without any anesthetic whatever; and--in a dentist’s office--teeth extracted without any anesthetic except the analgesic influence of zone therapy. Afterward I wrote to about fifty practising physicians in various parts of the country who have heard of zone therapy and are using it for the relief of all kinds of cases, even to allay the pains of childbirth. Their letters are on file in my office. This first article will be followed by a number of others in which Dr. Bowers will explain the application of zone therapy to the various common ailments. I anticipate criticism regarding these articles from two sources: first, from a small percentage of physicians; second, from people who will attempt to use zone therapy without success. We have considered this criticism in advance, and are prepared to disregard it. If the articles serve to reduce the sufferings of people in dentists’ chairs even ten per cent., if they will help in even the slightest way to relieve the common pains of every-day life, they will be amply justified. We do not know the full explanation of zone therapy; but we do know that a great many people have been helped by it, and that nobody can possibly be harmed.” THE EDITOR.

Each numbered line represents the *center* of its respective zone on the anterior part of the body. The tongue, hard and soft palate, posterior wall of the nasopharynx and oropharynx, and the generative organs are in ten zones, five on each side of the median line. The middle ear is in Zone 4. The eustachian tube and middle ear combined are in Zones 3 and 4. The upper surface of the tongue is in the anterior zones.
