A septum separates the two sacs internally. The spinalcolumn corresponding to the points f and g was Fig. 270. Tke interior of the Left Ventricle and ha$e of the Aorta, showing an Aneurism arising immediatelyabove the aortic valve. (Slightly smaller than the actual preparation.) The aneurism ruptured into the sac of the pericardium causing instantaneous death. Theletter, a, indicates the point of rupture. The aortic valve was (relatively) incompetent; tha leftventricle is dilated and hypertrophied. Fig.
