Eldridge gives an instance of separation of the symphysis pubis during labor,--a natural symphysiotomy.

A separation of 3/4 inch could be discerned at the symphysis, and in addition the sacroiliac synchondrosis was also quite movable.

The woman had not been able to walk in the latter part of her pregnancy.

The child weighed 10 1/2 pounds and had a large head in a remarkably advanced stage of ossification, with the fontanelles nearly closed.

Delivery was effected, though during the passage of the head the pubes separated to such an extent that Eldridge placed two fingers between them.
