His skull was fractured at the parietal eminence and the pericranium stripped off, leaving a bloody tumor near the base of the fracture about two inches in diameter.

The right humerus was fractured at the external condyle; there was a fracture of the coronoid process of the ulna, and a backward dislocation at the elbow.

The annular ligament was ruptured, and the radius was separated from the ulna.

On the left side there was a fracture of the anatomic neck of the humerus, and a dislocation downward.

The boy was trephined, and the comminuted fragments removed; in about six weeks recovery was nearly complete.
