This text investigates the practice of iridology as a diagnostic tool for assessing systemic health through the examination of the iris. Dorothy Graeme Hall, a prominent figure in Australian naturopathy, utilizes her clinical experience to outline the foundational principles of iris analysis. The book presents a framework for identifying physical markers within the eye that purportedly correspond to various organ systems and physiological conditions.

This work serves as a foundational reference for practitioners and students interested in the historical development of alternative diagnostic techniques. The content reflects the specific clinical approach of the author, providing a structured overview of iridology as practiced in the late twentieth century.
