Bronchitis is an inflammation of the lining membrane of the trachea and bronchial tubes. It may be either acute or chronic. If acute, there will be a slight fever and considerable cough. The treatment should be the same as that advised for coryza.

Chronic Bronchitis usually eventuates from an acute attack. The disease may be of years' standing. Those cases of death of elderly people from exhaustion, attended by cough and expectoration, and accredited to consumption, may usually be put down as bronchitis. Consumption rarely attacks persons after 40 or 45 years of age.

Treatment should consist partly in good living and warm dressing. Any of the bitter tonics, with iron, may be taken, together with some form of opium to relieve the cough. Iodide of potassium in five-grain doses, with two grains of carbonate of ammonia, taken after meals, will be found very useful.
