Operation, May 2d: Uterus found empty, cavity 14 1/2 cm.long.Median incision in abdominal wall; cyst walls exposed; seen to be very slight and filled with enormous vessels, some greater than the little finger.

On seizing the wall one of these vessels burst, and the hemorrhage was only rendered greater on attempting to secure it, so great was the friability of the walls.

The cyst was therefore rapidly opened and the child extracted by the foot.

Hemorrhage was restrained first by pressure of the hands, then by pressure-forceps and ligatures.

The walls of the cyst were sewn to the margins of the abdominal wound, the edge of the placenta being included in the suture.
