    cavity there was a small cavity the analogue of the right ven- tricle^ which hadj however, no connexion with the auricle, was -not larger than a nut, and did not give origin to any vessel. The source of the pulmonary supply and the relations of the systemic and pulmonary veins with the common auricle are not described.^ This case bears a close analogy to that described by Dr. Crisp, except that while in M. Bernard^s case the fully developed ventricle was the left, in that of Dr. Crisp it was the right. The defects in these cases might probably originate in obliteration, at early periods of foetal life, of one or other of the auriculo-ven- tricular apertures. In the volume of the Pathological Transactions for ] 864- 65, a specimen is described which was exhibited by Mr. C. Heath for Mr. Power, and which I have since had the opportunity of examining.^ It was removed from the body of a child which lived only twenty-four hours, and was also the subject of encephalocele. The heart gave origin to only one vessel, which arose from the right ventricle and gave off- first the pulmonary arteries, and then, while making its turn, the usual branches at the arch. The two auricles were distinct, but the foramen ovale was not entirely closed. The left auricle received as usual the pulmonary veins and opened into a small cavity—the analogue of the left ventricle, and this cavity had no artery arising from it, but opened by a small deficiency in the septum into the right ventricle. At the base of the heart there was a small vessel which had been cut across and was apparently the coronary artery. This must have derived its origin, either from the common trunk at a much higher point than natural, or from one of its branches. In this case, therefore, though the heart itself had undergone more complete development than in any of the cases last named, the separation of the primitive vessel into the aorta and pulmonary artery had apparently not taken place.
