![SECTION III, The Bronchi. The subjects to be considered are,—foreign bodies in the bronchi j bronchitis ; pituitous catarrh ; suffocative catarrh; dry catarrh ; pertussis ; ulcers ; hemorrhage ; dilatation ; polypus. I. Foreign bodies. The impalpable dust, which we occa- sionally inhale, is thrown off with the phlegm, which it causes to be secreted. But in those who are habitually exposed to breathe dust, among miners, leather dressers,, china manufacturers, needle grinders, and the like, marked consequences are produced by it; the bronchial membrane being perpetually irritated, bronchitis or consumption su- pervene. Solid bodies sometimes remain in the bronchi without pro- ducing irritation. More frequently a fatal result ensues. A boy, aged about twelve, who was travelling in a car- riage, happened to have an ear of rye in his mouth : the carriage being jolted, the ear of rye disappeared: it had dropped into the lungs, where it produced abscess. The abscess extended through the diaphragm into the liver. On inspection, the ear of rye was found sticking, part in the liver, part in the lungs. \_u. 62.] Any quantity of liquid introduced into the bronchi pro- duces instant suffocation. A case has been already adverted to, in which Dr. Watson and myself witnessed the instanta- neous extinction of life, through a gush of arterial blood down the trachea. Corvisart mentions the case of a stew- ard, who, being suddenly sick at stomach, made a violent effort to repress the vomiting ; when he fell to the ground, and expired. On examining the body, the larynx, trachea, and bronchi, were found filled with half-digested food. II. Bronchitis. a. Acute bronchitis.
