Examine and note character of contents; without re-laxing the grasp on the auriculoventricular orifice, open the right ven-tricle by an incision in line with the pulmonary artery and close tothe ventricular septum; insert the index-finger of the right hand andexamine the contents. The left heart is opened by grasping it as inopening the right. The auricle is incised near the appendix and im-mediately above the auriculoventricular septum, and its contents arenoted. The left ventricle is opened by an incision almost parallel to.

The pres-ence or absence of blood or clots in the left ventricle must be carefullynoted. Examine the great vessels as to abnormality, aneurysm, orother disease discernible externally; gross lesions involving the largevessel trunks, congenital defects, and the presence of thrombi or em-boli had best be determined before the heart is removed; and if pres-ent, it may be expedient to complete the dissection before removing theorgan.
