  • The air dilates the Eustachian tube, and is forced into the ear-drum. 
  • The difficulty as revealed by the post-mortem, lay in a thickening of the membrane of the Eustachian tubes. 
  • The inflammation of the mouth and throat is apt to extend up the Eustachian tube, thus impairing the sense of hearing.
