The right one lies along the posterior jiart of the jiosterior vena cava and the conunon iliac vein; the left one is similarly placed in relation to the aorta and left common iliac vein. They may be two inches or more (ca. 5-6 cm.) in length and nearly an inch (ca. 2 cm.) wide in large tlogs. In some cases there is a third small gland anterior to the large one in relation to the origin of the circumflex iliac vessels. In most cases there is a gland on each side of the middle sacral artery, l)etween that vessel and the internal iliac artery and its visceral brand i.
