August, page 71—The author of the letter entitled “Early days in heavy elements” should have been identified as John Joseph Gerald McCue of Lexington, Massachusetts.

October, page 122—in the guest comment by Charles Schwartz, it is the University of California, Berkeley, physics department that the author felt could benefit from a seminar on militarism and science, not the Department of Defense. In that same article, on page 124, the page designation for reference 2 should read pp III–19.
