title: Yellow Fever, as seen by the Medical Officers of the Royal Navy in the Nineteenth Century.
abstract: A critical review of old Naval Reports, showing how some difficulties in the epidemiology vanished when the mosquito means of transmission was discovered.Data are abstracted to show that the fatality, while generally exaggerated by missed cases, was often as high as recorded-also that latent immunization accounts for some types of immunity, and that the disease was always more virulent in Africa-where it probably originated-rather than in the New World.
