Various Attitudes during Parturition* in order to facilitate " pelvic torsion over the infant in process of birth," especially in the inter- mediate stages whilst changing between these attitudes. Cf. text of Chapter IX., p. 78. (a) Upright body, suspended from above. (b) Squatting or Crouching, more or less corresponding to our recumbent attitude with extreme flexion. (c) Recumbent attitude with raised legs and slightly raised trunk (usual attitude for parturition in many countries). (d) Maximal bending backwards, corresponding to our professional " Watcher's Suspension." * From Sellheim's " Die normale Geburt " in Halban und Seitz : " Biologie und Pathologic des Weibes," VII., I. (Berlin and Vienna, 1927, Urban and Schwarzenberg).
