THOMAS BOOKS will be true to those laws of quality that assure a good name and good will. Printed in the United States of America To R. A. Willis FOREWORD aur Living Chemistry Series was conceived by Editor and Publisher to advance the newer knowledge of chemical medicine in the cause of clinical practice. The interdependence of chemistryand medicine is so great that physicians are turning to chemistry, and chemists to medicine in order to understand the underlying basis of life processes in health and disease. Once chemical truths, proofs and convictions become sound foundations for clinical phenomena, key hybrid investigators clarify the bewildering panorama of biochemical progress for application in everyday practice, stimulation of experimental research, and extension of postgraduate instruction. Each of our monographs thus unravels the chemical mechanisms and clinical management of many diseases that have remained relatively static in the minds of medical men for three thousand years. Our new Series is charged with the nisus elan of chemical wisdom, supreme in choice of international authors, optimal in standards of chemical scholarship, provocative in imagination for experimental research, comprehensive in discussions of scientific medicine, and authoritative in chemical perceptives of human disorders.Dr. Cameron and Dr. Spector of London reveal the chemical spectrum of body reactivity to environmental injury, intrinsic and extrinsic, in its effort to preserve the integrity of the whole organism and of its constituent parts. The chemical approach is a medical milestone in the march of the human mind. Pathology initiated by Morgagni from the structural standpoint in organs, has been studied successively by Bichat in tissues; by Virchow in cells; and now by Cameron and others from the functional viewpoint in molecules and submolecules. The sequence of events which constitutes the living response to pathological injury is gradually being elucidated while different facets of the clinical picture are being obtained VI viii Foreivord through experimental exploration of cell chemistry by the newer techniques. It remains to be determined whether the response is
