A man, aged twenty-three years, was admitted with a diagnosis of chronic cardiac rheumatic valvular disease with auricular fibrillation with embolism of the left internal capsule and probable subacute bacterial endocarditis. Death occurred the following day. Autopsy showed, aside from the usual findings in the heart, a left auricie which was markedly dilated, the right border extending 8 cm. to the right of the midclavicular line in the region of the fourth rib. The left border lay in the arch of the aorta. The auricle had a capacity of .593 cc. of fluid after fixation. The mitral valve was stenosed to a slit-like opening, There was a mural thrombus within the left auricle.

At the post-mortem examination, a mass of coiled, mixed, red, pink and grey laminated clot with a rippled surface was found completely filling the right and left pulmonary arteries and extending for a short distance into their main branches. An entirely separate clot of similar formation and about 15 cm. long was caught in the foramen ovale in such a way that its greater length hung free in the left auricle and down into the left ventricle, ‘while a much shorter, thicker part projected into the right auricle. It seemed that the clot in the foramen ovale was of a similar sort to that in the pulmonary artery and not a part broken off. Photograph

A case of aneurysm of the right coronary artery is reported. There were no clinical findings suggesting this lesion. In addition to the coronary aneurysm and to nodular inequalities in the circumferences of the medium-sized arteries, there was a large saccular aneurysm of the abdominal aorta and a fusiform aneurysm of the There was an extreme degree of sclerosis of the right common iliac artery. coronary arteries with occlusion of the left ramus desoendens and extensive myocardial infarction.

A study of 148 cases of serial electrocardiograms indicates that sequential alterations of the R-T segment and of T, occurring in the course of a short period of time are strong presumptive evidence of myorardial infarction. Similar changes developing more slowly may be observed apart from myocardial infarction and may be due to dystrophic myocardial fibrosis following chronic progressive coronary The evidence available at the present time does not lend support to the sclerosis. view that the form of the electrocardiographic distortion can be regarded as a definite localizing sign of the infarct.
