Excerpt from Foreword: The relative constancy of the anatomic topography of Chapman's reflexes makes it possible to establish the location of pathology without knowing its nature. In considering the reflex effect on lymphatics, Dr. Chapman apparently assumed the existence of a neuro-lymphatic reflex (in the sense that we speak of neuro-vascular, neuro-muscular, neuro-humeral, etc.) as a part of the body's homeostatic mechanisms. The practicing physician will find in this book a valuable, useful therapeutic and diagnostic method.
