Abstract

How true! To those of us who had our early experiences in medicine before the days of an expanding number of laboratory and other technical aids, the clues which are there for the asking,—in the history and physical examination—point the path to diagnosis more often than not. This is difficult to teach in the face of physical and chemical methods which may seem to give greater aid because their results have a scientific ring, whether accurate or not, in milliequivalents, micrograms and the like.
