Pathol.: Pertu is, a spasmodic, infectious disease, usually of childhood, preceded by catarrh of from three to fourteen days' duration. It sometimes terminates in six weeks, but often lasts as many months, although danger is usually over at the end of six weeks. Emphysema is a dangerous complication. In fatal cases, pulmonary collapse, bronchial inflammation, nervous exhaustion, and general debility are the chief factors. Various specifics have been suggested, the chief being belladonna, Croton-chloral-hydrate, bromide of pota ium, and nitric acid with glycerine. Hooping-cough is more fatal in some years than others, and it is always dangerous to treat this disease without medical advice. It depends chiefly on irritation of the pneumogastric nerve by some special germ, producing the paroxysmal character of the cough.
