    examining along with him and Professor Fergusson, the double murmur from this cause was very distinctly marked.' The second heart sound perceived in aneurisms about the arch of the aorta, is generally admitted to arise from mere transmission from the ordinary site of its origin in the semilunar valves, aug- mented, it may be, by reason of the aneurism affording a-better medium of conduction of sound than the aorta in its normal state, not close to the sternum, and often covered by a portion ' of pulmonary tissue. And there is little reason to doubt that the first sound must also to a certain extent owe some degree of augmentation in its intensity, to transmission from the original site of the first sound of the heart, wherever this may be found to arise.
