Two of the patients were old peoplewho lived tranquil lives ; the third was a man who was forsome time under my care, and who died from a large aneurismof the descending thoracic aorta. (See figs. 268 and 269.) On microscopical examination, the thickened valve seg-ments and chordae tendineae are found to present the histo-logical characters of chronic endocarditis, which have beenpreviously described. The healthy mitral valve, when seen from above, presents a slit-like appear-ance ; in stenosis the slit is Fig. 193.—Stenosis of the mitral orifice, seen from above. {Natural size.) The left auricle, which is considerably dilated, has been cut open ; an ante-mortemclot (6) fills the appendix and projects into the cavity of the auricle, a, points to thestenosed mitral orifice; c, to the closed foramen ovale: d, to the outer and posteriorsurface of the left ventricle. Note—In fig. 195 the appearance of the valve as seen from the ventricular side isshown. T
