An expression, which, in common language, signifies the action of delivering, liberatio, but in the practice of obstetrics, means the extrusion of the secundines, either spontaneously or by the efforts of art. This completion of delivery- partus secundarius, secundinarum expulsio seu extractio, is produced by the same laws as the expulsion of the foetus. Sometimes, the after-birth follows the child immediately; at others, it is retained; and requires manual interference to remove it. The following are the chief cases in which this becomes necessary. 1. Intimate adhesion between the placenta and paries of the uterus. 2. Spasmodic contraction of the orifice of the uterus. .S. Hour-glass contraction. 4. Torpor or hemorrhage after the expulsion of the child, and, -5. Insertion of the placenta at the orifice of the uterus.
