The sequence of the chapters in this work rests chie?y on an anatomical and physiological basis, but occasionally sections have been inserted dealing with symptoms of frequent occurrence. Under the heading of the different diseases those symptoms only are mentioned which afford indications for treatment. Similarly, with regard to the causes and complications of certain morbid conditions, stress is laid upon those which call for prophylactic or remedial measures. To present a complete account of the various diseases, including questions relating to pathology, diagnosis, and prognosis, would have been beyond the Scope and purpose of this book.
