Corrections and Clarifications
In the letter of 23 October by Charles A. Gardner (p. 530), Dr. Gardner's address was incorrectly given as the Subcommittee on Human Resources and Intergovernmental Relations of the House Committee on Government Operations. Dr. Gardner was a AAAS Congressional Science Fellow assigned to that subcommittee through August 1992, but the views expressed in his letter were his own and not those of the subcommittee.
