Observations on Undulant Fever  The prevalence of undulant fever in the region about Aries (Bouches-du-Rhône) afforded Dr. Imbert an opportunity to collect seventy cases observed, for the most part by himself, in the Hôpital d'Arles. His researches, essentially of a clinical character, bring out a number of points bearing on the etiology; for example, the relatively slight rôle of goat's milk, the more important part played by the sheep as compared with the goat, and the frequency (around 50 per cent) of contagion through contact with the herds, which explains the frequency (four cases) of the disease in butchers. Dr. Imbert emphasizes the clinical polymorphism of undulant fever, particularly in the pseudotuberculous and the articular types. He points out also several rare complications that he has observed: hepatic, glandular, and grave nervous types. The prognosis is relatively good, there having been only three deaths in his series of seventy cases.
