Elements of the principles and practice of midwifery . Very shortly after the head is delivered, as has just been described,another movement of the head occurs, which has been termedrestitution. This movement consists in a restoration of the head,after it emerges from the pelvis, to its original oblique position, so 178 VERTEX PRESENTATIONS. that the face of the child, in the mechanism just described, turnstowards the left thigh of the mother (see fig. 14).
