After a retrospect of previous work on anencephalous births, Dr. Muralt proceeds to describe the skull and brain of two of those monstrosities. The first, a male child, born at full time, lived for two days, during which he cried lustily, swallowed, and showed the usual muscular motions and reflexes. His head resembled that of a cat, no forehead, the face prognathous, the nose and lips thick, and the eyes prominent. The head was covered with thick hair, and there was no roof to the cranium. The rudiments of the brain were shut in by a soft membrane. These structures are pictured in a large lithograph sheet, and their description fills seventeen pages of the Archiv.
