Abstract
A new statistical study on the distribution of mongolism in cities in Illinois, United States, from January 1, 1950 to December 31, 1956, permits us to verify an increasing frequency of this affliction associated with the concentration of fluorine in the drinking water.
This study follows a preceding inquiry on the prevalence of cases of mongolism born before 1950 in the same state.
Such inquiries should not be conducted in other countries without an evaluation of the contribution of fluorine from diet which varies from country to country.
The role of the advanced age of the mother, in the etiology of mongolism, would seem to reflect a slow and progressive accumulation of fluorine in the mother’s body.

Role des inhibiteurs enzymatiques dans l'etiologie du mongolisme
1) The low incidence of dental caries observed in mongoloid patients led to an investigation of the role of fluorine in this condition. 2) A statistical study of the geographical distribution of mongolism in Wisconsin, Illinois, Idaho, North and South Dakota (U.S.A.) shows a parallelism between the prevalence of this condition

Oligophrenie mongolienee et caries dentaires
Une enquête épidémiologique sur la fréquence du mongolisme dans quelques Etats du Midwest américain nous a permis de mettre en évidence les faits suivants: 1: un parallélisme entre la fréquence du mongolisme et la teneur en fluor de l'eau de boisson; 2: une rareté relative des caries dentaires chez les mongoliens; 3: une

Down syndrome, water fluoridation, and maternal age
It has been claimed that there is a positive association between the frequency of Down syndrome and the fluoridation of drinking water. It has also been suggested that this association is most pronounced in young women. Recent congenital malformations data obtained from birth certificates from large U.S. cities have been

Fluoride-linked down syndrome births and their estimated occurrence due to water fluoridation
Down syndrome (DS) birth rates (BR) as a function of maternal age exhibit a relatively flat linear regression line for younger mothers and a fairly steep one for older mothers with the second line intersecting the first line a little above maternal age 30. Consequently, overall DS-BR for all maternal
