 this way a kind of rotation of the limbs is effected, and they are brought 

 each to its proper side, and a little beneath the head. 



"When the faHus is firmly fixed in the pelvis, and retropulsion is

 complication.

Indications. — To bring the legs straight into the vagina is the object 

 to be attained ; and if the body and limbs are not firmly fixed in the 

 maternal pelvis, this can be accomplished without much trouble. But 

 when they are tightly wedged in the passage, then there is more
