“…The first case ( F 1) was a 56-year-old man who died as a result of a traffic accident after 14 years of fluorine exposure. The roentgenographic examination showed stage I11 fluorosis according to Roholm (1939) and Fritz (1958) ; chemical analysis of ash from a rib yielded a value of 1.15 per cent fluorine. The second case (F2) was a 64-year-old man who died from a brain tumour, diagnosed 4 weeks earlier, and who had had 10% years of fluorine exposure.…”
