FURTHER DISCUSSION OF COSMIC BIREFRINGENCE . The report by Borge Nodland and John Ralston (Update 317, 17 April) that they had uncovered an anisotropy in the amount of polarization of radio waves from distant galaxies is the subject of three items in an upcoming issue (most likely 8 Sept.) of Physical Review Letters: (1) A paper (J.F.C. Wardle et al.) reporting new radio and optical data that rule out any large anisotropy; (2) a comment by D.J. Eisenstein and E.F. Bunn questioning the statistical analysis of Nodland and Ralston; and (3) Nodland's and Ralston's reply in which they refute Eisenstein and Bunn. (Journalists can obtain copies from physnews@aip.org.)
