VERTEBRO-SACRAL. 

 With Devialiojis of the Head. 



This is one of the most cornmon causes of difficult 

 parturition. 



The feet, one or both, are presented normally, and 

 labor goes on for some time, but suddenly stops, and

If called when the head is just caught at the brim'

 chin, and raise the head, while traction is applied to the 

 cords. If only one fore-limb is presented, the position 

 is more difficult. It will be necessary to get both into- 

 position before anything else can be done. 



A more serious presentation, however, is caused by-
