The abnormalities of the cardiac mechanism which are responsible for various forms of cardiac arhythmia and disturbances in cardiac rate are now well understood, and have been especially well demonstrated by means of the string galvanometer. The analysis of disturbances of the cardiac mechanism, although of ever increasing diagnostic and therapeutic importance, is a field for original investigation which is fast losing its fertility. On the other hand, large problems lie before us in determining the essential causes of these cardiac disturbances. The progress of the treatment of cardiac disorders will be accelerated by the discovery of the now unknown changes, either within the heart or outside of it, which are responsible for these abnormalities of the cardiac mechanism. This is especially true of the large group of disorders characterized by disturbances in the generation of stimuli of the heart beat. These disturbances may predominate either
