"In the article entitled, 'An Isopter in the Intermediate Field of Vision,' published in the April, 1959, issue on page 130, the following three corrections should be made: (1) In the legend on Figure 1, the phrase 'width of fixation on bowl' should actually be 'point of fixation on bowl.' (2) In the same legend, '642 mm.' should be '1300 mm.' (3) In the legend on Figure 4, the word 'arc' should be replaced by the word 'one'."
