Erratum.
In the issue of 22 June, in the News and Comment article, "Congress says bioassay reports are stalled" (p. 1288), Philippe Shubik is identified as the "former director" of the University of Nebraska's Eppley Institute for Research in Cancer. Shubik is in fact on leave from that post until 1 July 1980. Norman Cromwell has been named acting director while Shubik is on leave.
