Experimenl and the results of disease have aided in proving these points. Position of Maximum [ntensity. In general the first sounds are loudest at the lower part of the prSBCOrdia, the second at the upper. Bui we especially distinguish the independent valve-elements that make id the diastolic sounds in the following manner: The especi up the systolic and Fig. Areas of cardiac murmurs (Gairdner for the areas ; and Luschka for the anatomy). The out-lines of organs, which are partialy invisible in the dissection, are indicated by very fine dottedlines; while the areas of propagation of valvular murmurs, as described in the text, have beenroughly marked by additional much coarser dotted and interrupted lines—the character of thedots being different in each of the four areas. A capital letter marks each area—viz., A, the circleof mitral murmurs corresponding with the left apex ; B, the irregular space indicating the ordinarylimits of diffusion of aortic murmurs, corresponding mainly with the whole sternum, and extend-ing into the neck along the course of the arteries; C, the broad and somewhat diffused areaoccupied by tricuspid murmurs, and corresponding generally with the right ventricle; D, the cir-cumscribed circular area over which pulmonic murmurs are commonly hea
