To the Editor:—In my article, entitled, "Actinomycosis of the Orbit" in the November, 1933, issue of the Archives, page 664, no reference was made to the interesting report on this subject presented by Dr. George A. Leahey at the convention of the American Ophthalmological Society in 1932. This was because volume 30 of the Transactions of the American Ophthalmological Society, in which Dr. Leahey's thesis can be found on page 457, became available, at least at the Barlow Medical Library of Los Angeles, only in April, 1933, when my paper was completed for publication.
