Summary
The fluorine content of Japanese foods was determined and the daily intake of fluorine by the individual from the rural diet in the central Japan was estimated with different crop years. In 1958 the fluorine intake of a person was 4.38 mg daily in winter, and in 1965 was 11.13 mg. This increase was due to the yearly increase of the fluorine content of Japanese foods. The contents of fluorine of rice and ''miso", which are the mainstay of the diet in Japan, showed geographical correlat
Among soft tissue organs which store fluoride (F-), the aorta contains the highest levels. [1-2]. Calcifications of arteries of the Monckeberg type have been reported in relatively young persons afflicted with skeletal fluorosis from endemic areas. [3-5] It was, therefore, of interest to determine whether or not there is a systematic correlation of F- levels with those of calcium (Ca++) in the aorta.
Methods. Aorta tissues were selected at random from 23 autopsies, without reference to sex,
We describe below a case of skeletal fluorosis occurring in a Hampshire man who presented with neurological complications, and whose condition was appreciably improved by operation. We believe that this is the first case of its kind to be reported from Britain, and also the first case of skeletal fluorosis with neurological involvement in which surgery has been attempted with benefit.

All cases of chronic fluoride intoxication with radiculomyelopathy have been previously reported from India (1, 2). This paper describes a patient with clinical, necropsy, and toxicologic findings of this disorder, whose problem is of special interest because he lived in an area where cases of advanced fluorosis would not be expected.
CASE REPORT
A 64-year-old white male was admitted to the Veterans Administration Hospital, McKinney, Tex., on May 11, 1962, because of severe respiratory d

BY the time that Brantford, Ontario, began to fluoridate its water supply in 1945 a great deal of information had been obtained from various parts of the word concerning the effect of naturally fluoridated water on dental caries. This information showed that the incidence of tooth decay is greatly reduced in populations consuming from birth naturally fluoridated water at a level of about one part per million. No ill effects at this level were observed. We therefore wished to det
