While this book is published under the auspices of the Canadian Memorial Chiropractic College, and no author is listed, credit must be given A.R. Petersen, D.C, who contributed the bulk of the material. His early laborious work of reading manuscripts on neuro-dynamics and vascular physiology, his diligence in organizing the material, his ultimate discovery of the spinal neuropathy, and his vision of scientific practice for the profession, merits the approval of the entire Chiropractic profession.
