The rectal sheath covers the lower three inches of the howel, grad-ually disappearing toward the anus; it lies immediately over thesuperior hemorrhoidal vessels. The vagina also has an envelope,which may be traced along the tube to its lower end, where it becomeslost in the dee]) perineal fascia (.). Itcovers the vaginal plexuses and con-stitutes the externa] layer of the va-ginal wall. The bladder also receives supportfrom the same source, the anteriortrue ligaments being formed by twoprocesses which extend from the hackof the pubes (the anterior attachmentof the fascia) to the neck of the blad-der; between these special processesthe recto-vesical fascia is said by El-lis to descend to the triangular Liga-incut of the urethra, of which it formsthe posterior The lateral liga-ments of the bladder are formed byfascial bands which are attached tothe postero-lateral border of the vesi-cal
