A ventricular diastolic murmur may thus have four distinct solu-tions among organic valvular diseases. If this area is mitral, it isa murmur of mitral obstruction ; if its area is aortic, it is a m urmur ofaortic regurgitation ; if its area is tricuspid, it is a murmur of tricuspidobstruction ; if its area is of the origin of the pulmonary artery, themurmur denotes regu

The most frequent combinations of these murmurs are thosewhich denote— 1. Combined aortic obstruction with regurgitation, indicated byventricular systolic and ventricular diastolic murmurs. 2. Mitral obstruction and regurgitation, indicated by auricular AREAS AND SIGNIFICANCE OF CARDIAC MURMURS. 591 systolic murmurs, sometimes bj ventricular diastolic and ventricu-lar systolic murmurs. Fis;. 15.*. * The Heart; its several parts and great vessels in relation to the front of thethorax. The lungs are collapsed to their normal amount, as after death, exposingthe heart. The outlines of the several parts of the heart are indicated by very finedotted lines. The area of propagation of valvular murmurs are marked out bymore visible dotted lines. A, the circle of mitral murmur, corresponds to the leftapex. The broad and somewhat diifused area, roughly triangular, is the region of tricus-pid murmurs, and corresponds generally with the right ventricle where it is leastcovered by lung. The letter C is in its centre. The circumscribed circular area, D, over which the pulmonic arterial murmursare commonly heard loudest. In many cases it is an inch, or even more, lowerdown, corresponding to the conus arteriosus of the right ventricle, where it touchesthe walls of the thorax. The internal organs and parts of organs are indicated by letters as follows : 7,
