There is a very peculiar waddling -ait, a marked lordosis,and the shoulders are carried far back. The rear view of thepatient shows an unusually wide separation of the thighs as theindividual stands erect with the heels together.

The weight of the body falling mainly onthe sound leg, the corresponding innominate bone is pushedupward, backward, and inward, diminishing the area of in-trapelvic space on its own side. Torggler reports an inter-esting case of this kind in which the disability of one legwas due to In the absence of both lower ex-tremities there is the characteristic sitz-pelvis, in which theinnominate bones are usually rotated on an anteroposterior axis,so that the crests of the ilia are approximated and the tuberosi- 1 Pratique des Accouchements, iii, p. 413 ; according to Schauta, the onlycase on record. 2 Centralbl. f.
