    Fig. 5. Babbit. Nine days and four hours. Longitudinal section through the iter venosum. Fig. 6. Babbit. Nine days and a half. Sinus reuniens receives umbilical vein, and latter receives the jugular or anterior cardinal vein. Figs. 7a to 14a. Longitudinal sections of Babbit’s embryo at beginning of ninth day. This series demonstrates the continuity of the cardiac and pleuro-peritoneal coelom behind the vitelline veins, and also the opening of the umbilical vein into the vitelline. Figs. 1 5b to 1 9b. Transverse sections of Babbit’s embryo of nine days and four hours. This embryo closely resembled fig. 4. The series consisted of 153 sections. 15b = sec. 19. 16b = sec. 44. 17b = sec. 57. 18b = sec. 77. 19b = sec. 139. Figs. 20c to 22c. Coronal sections of Babbit’s embryo of nine days and five hours :— 20c. Through iter venosum. 21c. Through sinus reunions. 22c. Through septum transversum and liver. Figs. 23d to 30d. Babbit’s embryo of second half of ninth day. Liver, placenta, course of veins, and relation of embryo to wall of uterus (after it has undergone rotation). Fig. 30. Placental region of Babbit beginning of tenth day. Fig. 31. Coronal section through Babbit’s embryo at beginning of tenth day. The relation of embryo to wall of uterus and placental region, especially the relation of placental region to hinder part of the splanchnopleure. Figs. 32e to 34e. Longitudinal sections of Babbit’s embryos of nine days and sixteen hours. 32e. Through iter venosum. 33e. Through Cuvierian duct, jugular and posterior cardinal veins, umbilical vein, and sinus reunions. An arrow has been placed in the iter venosum. 34e. Belation of umbilical vein to duct of Cuvier (through outer wall of iter venosum). Fig. 35. Coronal section of Babbit’s embryo of fourteen days, to show the dorsal diaphragm. Fig. 36. Almost transverse section through Babbit’s embryo of nine days and sixteen hours at level of Cuvierian duct and iter venosum. The villous pro- jections of the liver and venter are shown. Figs. 37r to 44f. Transverse sections of Babbit’s embryo of latter part of tenth day, to show sinus reunions and septum transversum, liver, and great veins. Fig. 45. Coronal section of embryo of latter part of tenth or eleventh day, to show great veins and commencement of dorsal diaphragm. Fig. 46. Early Human embryo. Transverse section through Cuvierian duct and iter venosum.
