This cough may start up from sympathy; but then it is always less sonorous, harsh, and grating. It is also less spasmodic, and likewise less the consequence of particular causes. When the larynx is the seat of the affection, the cough, should it once begin, continues for a considerable time; and cold air or excitement will invariably induce it. In bad cases every act of inspiration is followed by a kind of noise intermediate between a grunt and a cough. Sometimes the breathing is accompanied by a species of roaring; and I have seen one case in which a blood-hound had every symptom of laryngismus stridulus, or the crowing disease of the human infant.
