Abstract : Ikutaro Hirai reported in a paediatric journal issued in Japan, Acta Paediatrica Japonica, in 1923 that the so-called meningitis in infants was a chronic lead poisoning caused by the mother's face powder containing lead. This report aroused a continuing wave of publications on the so-called meningitis in infants. As many as 265 articles on the disease appeared in Acta Paediatrica Japonica from 1923 to 1930. In 1930, a partial amendment to the regulations of toxic coloring agents was made, imposing legal controls on cosmetics using white lead. In this study, we clarified the controversy about Hirai's discovery, presenting his nine articles published in Acta Paediatrica Japonica. They included two reports on aetiology, two reports on prevention and treatments, two records of a special lecture containing questions, answers and additions and three miscellanies with his supplementary comments.
