    where there was marked congenital pulmonary stenosis. The bronchial arteries and other accessory branches derived from the intercostals were so enlarged that some of them were equal in size to the radial arteries, but one was espe- cially struck by the number rather than by the size of the accessory arterial communications; they formed Fig. 4. Heart of a girl, aged two years, showing complete arrest of the development of the infundibulum, a. Unopened heart viewed from the ventral aspect, b. Right ventricle opened in the same specimen. 1, Pulmonary artery; 2, aorta; 3, position of infundibulum; 4, ostium infundibuli; 5, body of right ventricle and large interventricular orifice; 6, tri- cuspid ; 7, right auricle; 8, left ventricle ; and 9, left auricle. a leash like plexus. The arteries accompanying the phrenic nerves were greatly enlarged and sent branches to the lungs. In those cases where there is complete arrest of the infundibulum, the arterial system of the lungs is filled from the systemic circulation. To merely live—and that is the condition of patients with such hearts—a wonderfully small supply of oxygenated blood is apparently sufiBcient.
