    chest walls, in the abdomen, in the nares, larynx, trachea, or bronchi, we may meet with conditions giving rise to it. Weakness Fio. 2.—Bronchitis; Pulmonary Collapse; Catarrhal Pneumonia in a child 14 months old. Low temperature range indicates period of collapse. of the thoracic parietes, whether of bones or muscles, and associated with this, a general condition of debility and loss of muscle and nerve tone, as seen in rachitic children, in whom, when there is any bronchial catarrh, as there generally is, and when this is associated with a loss of rigidity in the bony frame- work of the chest, you have pulmonary collapse to a greater or less extent almost invariably present. In like manner, when from whatever cause tlie abdomen is distended, we liave, as a natural result, an obstacle to the free descent of the diaphragm, and con- sequent weakening of the inspiratory act, which acts directly in the production of collapse. Nasal or laryngeal or tracheal, as well as bronchial stenosis, from whatever cause, will likewise tend to produce it. Thus, in croupous or dii)htheritic hiryngitis, or laryngismus stridulus, we meet with it. Before alluding to causes in the bronchial tubes themselves, I wish merely to refer in passing to the question, which the limits of the paper forbid my discussing, how far any or all of these causes may operate in the produc- tion of collapse without the concomitant existence ot bronchial catarrh. There are grounds for believing that in atrophied and debilitated children, with rickety delormity of the chest, atelectasis may be gradually and slowly produced by physical causes a[)ait from any intra-bronchial ])lugging or occlusion. Ihere can be no doubt, however, that in the larger proportion of cases bronchial catarrh pre-exists, and, as a result, gradual blocking ot with secretion directly causes collupse. I he pathology o p ug- ging” of the tubes, as it is called, has been carefully woi cei on ever since Lamiiec opened up the subject in his classica wntings.
