Fig. 9. Dissection of an embryo pig 16 mm. long in which the vascular system has been injected with India ink through the umbilical artery. The specimen shows the prevertebral plexus of the cervical and upper dorsal region with the developing v. hemiazygos. X1S.

D. c., ductus Cuvier; v. HA., v. hemiazygos; v. J. K., v. jugularis externa; v. TE., v. thoraco-epigastrica.

Fig. 10. Transverse section of an embryo pig 16 mm. long in which the vascular system has been injected with India ink through the umbilical artery. The section passes through the cephalic pole of the Wolffian body and is to show the relation of the v. azygos to the prevertebral plexus. The section is unstained and is 2. r iO /u thick. It is about the stage of fig. 13. X34.

A., aorta; v. c. p., v. cardinalis posterior within the Wolffian body; v. HA., v. hemiazygos; v. M. A., v. mesialis anterior of the Wolffian body; v. M. I., v. mammaria interna; v. TE., v. thoraco-epigastrica; v. v., v. ventralis of the Wolrnan body; w. B., Wolffian body.
