    ovary. In this subject both branches send long (36 and 34) and short (38) helicine arteries to the ovary. The oviducal segment ends and begin§ where its two branches anastomose (6 and 9). The oviducal segment emits rami laterales ovari (36) and rami laterales oviductus (31, 32 and 33). It begins at the bifurcatio ar- terise uterinae medial (6) and ends at the bifurcatio arteriae uterinae proximal (9) and is generally accompanied by two veins. By severing the lateral branches (31, 32, 33) of the ramus oviductus close to the oviduct one can remove the oviduct without cutting the genital vascular circle or the ramus oviductus. By severing the lateral branches (38) of the ramus ovarii the ovary can be removed without cut- ting the ramus ovarii or the genital vascular circle. In the present pregnant case the ovarian vascular circle (6, 7—7, 9 and 6, 8— 8, 9) is extremely well developed and prominent on both sides. It is one of the original Wolffian vascular arches.' The rule is that the ramus ovarii sends five short very spiral helicine branches (38) to the ovary and the ramus oviductus sends three long sinuous helicine branches (34 and 36) to the ovary and three large long sinuous branches (31, 32 and 33) to the oviduct. It has a phenomenal development during pregnancy in man and animals. The oviducal ampulla, receptaculum seminis, is attended by an enormous blood supply (33 and 40). This segment extends from the oviducal pole (9) of the ovary to the aorta near the origin of the renal artery (12). In this segment is found the proximal arterio-ureteral crossing (n) with the proximal arteria ureterica. The ovarian segment begins at the proximal bifurcation of the utero-ovarian artery, Bifurcatio arterise uterinae proximal (9), and ends at the original location of the Wolffian body along the aorta (12). From the proximal arterio-ureteral crossing (11) the ovarian segment passes close to and externally parallel with the ureter (20, 19) as far as the ligamentum suspensorium ovarii (9). In its course it sends several branches to the ureter, peritoneum and adjacent structures, but especially strong branches to the ligamentum suspensorium ovarii (35 and 34), where numerous additional arches and branches may be recognized in pregnant subjects. It is verv spiral in its distal portion but straight from its origin in the aorta to the proximal arterio-ureteral crossing (11). It develops rapidly during gestation in man and animals. The ovarian segment lies in a vast bed of connective tissue and possesses extensive mobility. This segment extends from the deep epigastric (21) to the ramus oviducts near -he utero-oviducal angle (6). It lies in the center of the ligamenthm rotun- , urn uteri and is very tortuous. It begins practically at the middle bifurcation of t e utPr°-°varian artery, bifurcatio arteria uterinae medial f(A snH THE OVARIAN SEGMENT. 9, 10, 11 and 12. 9, 10, 11 and 12.
