Fluorine in Plants and Animals, In 1802 Domenico Pini Morichini discovered the presence of fluorine in fossil ivory (157). He later detected it in the enamel of the teeth, and Berzelius soon confirmed the discovery and showed that fluorine is also a normal constituent of bone (158,159, 165). The presence of excessive amounts of fluoride in drinking water causes the well-known mottling of the enamel of children s teeth (160), but small amounts of fluoride protect the teeth from dental caries (161).

Fossilized ivory is a popular material in the few places in the world where it is found in commercial amounts because it does not fall within the restrictions... 

W. Cruickshank recommended use of CI2 as a disinfectant (widely used in hospitals by 1823 notably effective in the European cholera epidemic, 1831, and in the outbreak of puerperal fever, Vienna, 1845) Fluoride found in fossil ivory and teeth by D. P. Morichini (soon confirmed by J. J. Berzelius who found it also in bones)... 

Klaproth analysed datolith, gypsum, and barytes. He missed the fluorine content of apatite, which was detected by Pelletier, but he detected sodium in cryolite and the fluorine content of teeth and fossil ivory, confirmed by Berzelius. He showed that native iron is free from nickel, which is contained in meteoric iron, and analysed chrome ironstone. He described the manufacture of alum at Tolfa. He confirmed (1801) an observation of Kennedy of Edinburgh (1797) that basalt contains soda, and discovered potash (previously regarded as confined to the vegetable kii dom) in the mineral leucite (1797). He made many analyses of ancient metal objects and glazes. ...
