In the article by Dr. Adrien Bleyer, entitled "Role of Advanced Maternal Age in Causing Mongolism: A Study of 2,822 Cases," which appeared in the January 1938 issue (Am. J. Dis. Child. 55:79, 1938), there were a few errors in figures:
In the table on page 82, entitled "A Comparison of Births of Mongoloid Imbeciles Occurring in Nine Quinquenniums with Births Occurring in the General Population of the United States in Similar Periods," the fifth, sixth and seventh percentages should have been 5.1, 3.5 and 0.3 (instead of 0.9, 0.3 and 0.03).
Similarly, in the ratios on the following page, "5 to 1" should replace "25 to 1"; "7.5 to 1" should replace "75 to 1," and "12.5 to 1" should replace "125 to 1."
Like substitutions should be made in the conclusions on the last page.
