of the Larynx and Trachea following Incision of Throat.

The photographed specimen (Photo. III.) of cut-throat was taken from a woman whose trachea was completely divided at the third ring. On the tenth day after the injury she was nearly asphyxiated, and a canula had to be inserted. She lived for a year. No destruction of the web had been attempted.
The web will be seen not to be a simple layer of mucous membrane, but a thick wedge-shaped union of the whole of the tissues, and this will explain the difficulty there would be in first destroying it, and afterwards keeping the ulcerated sides of the canal from re-uniting.
