Testut and Marcondes report a description of a lung with six lobes.
Anomalies of the Diaphragm .-- Diemerbroeck is said to have dissected a human subject in whom the diaphragm and mediastinum were apparently missing, but such cases must be very rare, although we frequently find marked deficiency of this organ.

Bouchand reports an instance of absence of the right half of the diaphragm in an infant born at term.
Lawrence mentions congenital deficiency of the muscular fibers of the left half of the diaphragm with displacement of the stomach.

The patient died of double pneumonia.

Carruthers, McClintock, Polaillon, and van Geison also record instances of congenital deficiency of part of the diaphragm.

Recently Dittel reported unilateral defect in the diaphragm of an infant that died soon after birth.
