Indeed, this sickness frequently plays an im- portant part in paroxysmal diseases, occurring, as it does, in its slightest form of ' sick-headache,' or of what may be termed ' sick-giddiness,' or in the form or in the course of an apoplectic seizure. 2.—The Lividity and Tumidity in Paroxysmal Affections. 46. After their paroxysmal form, lividity of the countenance, either with flushing and turgescence of the face and neck, or with pallor, is the most charac- teristic phenomenon of these seizures. How is this phenomenon produced ] 47.
