    that the next murmur is a tricuspid regurgitant one, and that the area over which the latter is audible depends upon the degree of distension of the right heart, and the measure in which it approaches the thoracic wall, so soon do the precordial murmurs range themselves under simple and orderly law. The varying degree in which the murmur is audible, even over the manubrium, depends entirely upon the degree of the distension of the right side of the heart. There is, it is here contended, no aortic murmur in anaemia or chlorosis. The murmur which has been supposed to be aortic in origin is really tricuspid. What has been here shown to be the primary murmur is produced in the pulmonary artery, but it has not been, to the same extent, confounded with the tricuspid murmur as the so-called aortic murmur has been; neither was it this murmur which led to the belief that the basic hcemic murmur was aortic in origin. The classical basic murmur was undoubt- edly what is here held to be the tricuspid murmur. Having thus refuted the contention that the hcemic basic murmur is situated at the orifice of the aorta, it necessarily follows that the murmur in the carotid artery, which was supposed to be the aortic one conducted upwards, has likewise no existence. It is however not to be forgotten that, in several of the older descriptions of the hcemic or basic inorganic cardiac murmur, it was clearly brought out that the murmur was but feebly, if at all, conducted into the vessels of the neck. We may go further and say, that as it is not conducted into the carotid, it cannot have its origin at the aortic orifice; for that an aortic systolic murmur should be heard loudly over the sternum and not in the carotid is a physical impossibility. The arterial murmur was, however, frequently regarded as G
