Graphic Methods in Heart Disease.

In this book nothing is to be found concerning the examination of the heart by the ordinary methods of palpation, percussion and auscultation. It is intended solely as an introduction to the clinical study of disease of the heart by the aid of graphic instrumental methods. The beginner who is perhaps disheartened at his early attempts to study the various types of venous pulse, the extrasystoles or the epigastric pulsations, will here find help both in methods of using the instruments and in the interpretation of their records. He will naturally be led to consult the more extended writings of Wenckebach, Tigerstedt and Mackenzie. The latter writer is the inspirer of this little work by Hay, and has written a brief, yet interesting introduction. The mechanical features of the book are excellent and the 128 illustrations are unusually well executed.
