On November 12 search was made for B. influenzæ in 50 normal drafted men who had assembled at Hot Springs, Ark., on that date preparatory to entraining for Camp Pike. These men were all from isolated farming communities where influenza was only moderately prevalent and where there was little opportunity for the wide dissemination of B. influenzæ such as occurs when large bodies of men are assembled in camps. Twelve of the 50 gave a history of influenza within the preceding eight weeks. The cultures were made by the same methods as those used at Camp Pike, the laboratory car “Lister” being taken to Hot Springs for that purpose. The incidence of B. influenzæ was only 22 per cent. In striking contrast with this figure are the figures of 50 and 68 per cent obtained in the last two groups studied at Camp Pike after the epidemic had swept through the camp: 24 of the 51 men in these groups had influenza during the epidemic.
