“…The studies of Plotke, Eisenberg, Baker, and Laughlin (1949), Alexander and Schoch (1949), and Alexander, Schoch, and Mantooth (1949) in small series of early syphilis patients and their contacts are well known, as are the views of Leifer and Martin (1946), Durel (1954), and others on the epidemiological effectiveness and applicability of preventive treatment. Only passing reference will be made therefore to the work of these investigators as well as to the practical experience of Eagle, Gude, Beckman, Mast, Sapero, andShindledecker (1948, 1949), Campbell, Dougherty, and Curtis (1949), Babione, Hedgecock, and Ray (1952), and similar unpublished experiences of British workers in the prevention of gonorrhoea or syphilis among naval personnel in ports.…”
