The first edition of this textbook of internal medicine appeared in 1923. The author is a pupil of the clinician and teacher Friedrich Müller. He has written this book on internal medicine as a guide to the young physician and medical student. He devotes 130 pages to the infectious diseases. Then follow circulatory diseases (seventy-three pages), respiratory diseases (sixty pages), blood diseases (twenty-five pages), diseases of the digestive tract (112 pages), of the urinary tract (fifty-two pages) and of the ductless glands (twenty pages), metabolic diseases (forty-eight pages) and diseases of the locomotor apparatus (twelve pages) and the nervous system (124 pages).
