With the introduction in recent years of so many mechanical aids in cardiac diagnosis, a book which sets forth the information that may be gained by simple auscultation is refreshing. Chapters are devoted to heart sounds, cardiac irregularities, cardiac murmurs and miscellaneous auscultatory findings. Along with a description of the acoustic phenomena are heart sound tracings and electrocardiograms. The authors emphasize that these tracings are unnecessary in general practice but are used in the text to illustrate what has been heard and to help visualize the points discussed. They show how by careful auscultation one may be able to make many diagnoses at the bedside without resort to the roentgenogram or the electrocardiogram. In the words of the authors, "When the cost of medical care is necessarily increasing, it is imperative to derive all possible help from such an inexpensive and expedient tool as the stethoscope."
