The causes of the impulses, whose course has been trac( are certainly numerous. Aortic, coronary, and myocard lesions lead to secondary changes by interfering with t nutrition of the heart muscle. This may occur either diminution of the blood supply, long ago suggested by All Burns,* or by direct irritation of the sensory nerve endin Pericardial affections, aneurysms, and tumours occasiona produce symptoms like angina pectoris; but they are, as rule, not so definite. Further, there can be no doubt tl cardiac stress, leading to strain, originally mentioned Cahen ^ and Eichwald,^ niay, in the absence of distinct stn tural alterations, produce a considerable degree of cardiac pa A recent paper of Mackenzie's gives a most excellent su mary of our present knowledge of this aspect of the subje Fie concludes that angina pectoris will, in all probability, found to depend upon impairment of the function of C( tractility. Toxic influences can easily be understood as fact giving rise by irritation to considerable discomfort. Ref action, taking its origin even in the most distant parts of 1 body, is by no means an uncommon cause of cardiac pa acting, as it does, by increasing the strain on the hej In this connection, it may be added that Russell® lately, a very interesting paper, described the relation of angi pectoris to reflex action of abdominal origin.
