    widest part II-4: inches, and in length 4J. The bulk was chiefly due to the right or pulmonic heart which was distended with grumous blood. External surface healthy, except the old ad- hesion above-named, on the front near the apex. On placing the heart with its anterior surface upwards, the anterior longi- tudinal furrow with its vessels holds the usual position, ending above and to the right side of the apex. The aorta and pulmonary artery are seen to be reversed in position. From the right side of the heart springs the aorta, having, on each side of its origin, the right and left auricular appendages. The aorta is only half an inch in diameter, its arch is formed as usual, and the customary three branches are given off from it. All three are small, and in proportion to the size of the trunk from which they arise ; the innominata bifur- cates within half an inch of its origin. Immediately behind the origin of the aorta is placed that of the pulmonary artery, whicl^ measures an inch and three quarters in diameter, at its com- mencement, and passing up behind the ascending part of the aorta, it bifurcates as usual under its arch ; and just below its bifurcation its diameter is 2 inches. The ductus arteriosus is quite closed. The right auricle and the right side of the ven- tricular part of the heart appear unduly large; this auricle is much larger than the left one, both as to its sinus and its appendage. The vense cavse enter the right auricle normally, and the usual four pulmonary veins are normally connected with the left auricle. Internally: The ventricular division of the heart is one large cavity, no trace of septum is visible, the organ having been freely opened from the apex towards the base. The reticula- tions of the columnse carneas on the right side are not nearly so numerous and complicated as those on the left side; the musculi papillares are nearly as large on the right as on the left side, and the ventricular wall on the right is very nearly as thick as that on the left side. The aortic aperture is in the position of that of the pul- monary artery, and the latter in that of the former; the orifice
