    oi the lungs, and to the large blood-vessels connected with the heart, is reflected and continued over the surface of the heart, so that the latter is equivocally said to be with- out the pericardium. At the points where the pericar- dium is attached to the large blood-vessels, it forms several angles, which are named its cornua. The nervous threads, 6, 6, distributed on the pericardium, derive their origin from the great intercostal nerves 7.* * * § The letter d is placed on the right ventricle of the heart ;f d, on the right auricle;J d, on the left auricle;§ e, is the aorta, |] which derives its origin from the left ventricle, % as seen in Plate II., Fig. 1, letter g; and F indicates the pulmonary ar- tery,** arising from the right ventricle. The small arteries ramified on the surface of the heart, are the coronary arteries,'!'']' at the side of which are seen the branches of the coronary vein; r indicating the right artery; s the left artery; the further distribution of both of which is seen in Fig. 1 of Plate II. The white nervous threads encircling the aorta and pulmonary artery, are the cardiac twigs formed by the great intercostal nerves and par vagum. * The attachments of the pericardium should be considered by the practitioner, otherwise he is liable to be deceived in the pulsations of the heart; for that which is felt at the scrobiculus cordis has been mistaken for aneurism of the abdominal aorta. Named also anterior, or pulmonic. | Termed also pulmonic, or anterior, or sinus venosus, or sinus venarum cava- rum. § Also named posterior, or systemic, or sinus venosus, or sinus pulmonalis. || Named also systemic, or systematic artery. Named also posterior, or systemic, or systematic, or aortic ventricle. ** Also named pulmonic. ff Also named cardiac. Although these arteries are almost invariably two in number ; yet in some cases which have occurred only one has been found, in others three. Where two occur, the one is sometimes larger, and supplies a great por- tion of the space allotted for the other.
