English, "Causes of Blindness in Pennsylvania : An Analysis of a Group of Over Thirty Thousand Blind Eyes," which appeared in the November issue (26: 797, 1941), the last three paragraphs on page 805, beginning "His criticism of the type of detail," belong to the remarks made by Dr. Conrad Berens and should be transposed to page 806 after the paragraph beginning "He criticizes the length of the committee's classification."
