The condition of the vascular elements between the systemic and pulmonic arches in mammals is of great interest as there is apparently conflicting testimony as to their meaning. In the human embryo there exists a complete vessel between the systemic and pulmonic arches. In the specimen reconstructed and described by Zimmermann, it consists of an offshoot from the systemic arch — springing from that vessel and uniting again with it. In the two cases figured by Tandler, it arises from the truncus arteriosus and empties into the pulmonic arch. Fig. 8 is a copy of a diagram by Tandler showing the anatomical re-.
