    1 into the right auriculo-ventricular aperture, 3 into the right ventricle, 1 into the right ventricle and pulmonary artery, 7 into the pulmonary artery, and 3 into the left auricle. Of the series of cases in which the sacs were situated in the ascending portion of the aorta, 6 opened into the vena cava superior, 1 into the right auricular appendage, 1 into the right ventricle, 1 into the right ventricle and pulmonary artery, and 3 into the pulmonary artery. In one of the cases in which the whole arch was dilated, the connection was with the vena cava superior; in the other, with the pulmonary artery. In the single case of the fourth class it has already been mentioned that the supposed sac opened into the left pulmonary branch. Thus, aneurysms at the commencement of the aorta generally open into either auricle, the right ventricle, and especially the pulmonary artery; while those Avhich arise from the ascending aorta, form connections with the vena cava superior, and less frequently with the pulmonary artery. Taking the whole of the cases into consideration, without reference to the precise portion of the aorta from which the aneu- rysmal sacs arise, and adding to the cases collected in the appendix the six others of which the specimens are stated by Dr. Thurnam to exist in museums, and the four described by Eokitansky, of forty-three cases, in 7 the aneurysms opened into the vena cava superior, 5 into the right auricle or auriculo-ventricular aperture, 4 into the right ventricle, 2 into the right ventricle and pulmonary artery, 18 into the pulmonary artery, 1 into the left pulmonary branch, 3 into the right pulmonary branch, and in 3 into the left auricle. Dr. Hope has described and figured a case^'' in which an aneurysm, at the origin of the aorta, was supposed to have burrowed behind the attachment of the valves, and so to have opened into the cavity of the left ventricle. But, while there can be no doubt that aneurysms of * Morbid Anatomy, Figs. C and 7, p. 20.
