Pyle reports a case successfully treated, as follows:-- "Lewis W., ten years old, white, born in Maryland, and living now in the District of Columbia, was brought in by the Emergency Hospital ambulance, on the afternoon of November 10th, with a history of having been run over by a hose-cart of the District Fire Department.

The boy was in a state of extreme shock, having a weak, almost imperceptible pulse; his respirations were shallow and rapid, and his temperature subnormal.

There were no signs of external injury about his thoracic cavity and no fracture of the ribs could be detected, although carefully searched for; there was marked emphysema; the neck and side of the face were enormously swollen with the extravasated air; the tissues of the left arm were greatly infiltrated with air, which enabled us to elicit the familiar crepitus of such infiltration when an attempt at the determination of the radial pulse was made.
