    occasioned by bronchitis. But if these rhonchi are heard over any particular part of the chest louder than elsewhere, and the sound gradually becomes fainter as we proceed to the trachea, they indicate bronchitis, whether the larynx or trachea are free from disease or not. In many long standing cases of this affection, when the mucous membrane has become thick- ened, the supply of air to the lungs falls short of the normal quantity; and although the period of respiration may be occasionally prolonged by an effort of the will in inspiration, this cannot be persisted] in for any long continuance. Con- sequently, in such cases, some of the air cells will not be fiUed at all, whilst others will only be partially distended, and these, like other parts of the body from w^ant of use, will undergo a certain amount of waste and decay. Although the disease in the laryngo-tracheal tube may be removed, we possess no means of restoring the wasted tissue of the lung. In such cases a defi- ciency of expansion may generally be observed in the upper regions of the chest, as well as a deficiency of the respiratory murmur.
