Many of my friends have been anxious ever since Osteopathy became an established fact, that I should write a treatise on the science. But I was never convinced that the time was ripe for such a production, nor am I even now convinced that this is not a little premature. Osteopathy is only in its infancy, it is a great unknown sea just discovered, and as yet we are only acquainted with its shore-tide.When I saw others who had not more than skimmed the surface of the science, taking up the pen to write books on Osteopathy, and after having carefully examined their productions, found they were drinking from the fountains of old schools of drugs, dragging back the science to the very systems from which I divorced myself so many years ago, and realized that hungry students were ready to swallow such mental poison, dangerous as it was, I became fully awakened to the necessity of some sort of Osteopathic literature for those wishing to be informed.This book is free from quotations from medical authors, and differs from them in opinion on almost every important question. I do not expect it to meet their approval; such a thing would be unnatural and impossible.It is my object in this work to teach principles as I understand them, and not rules. I do not instruct the student to punch or pull a certain bone, nerve or muscle for a certain disease, but by a knowledge of the normal and abnormal, I hope to give a specific knowledge for all diseases.
