Letter from Thomas Gold to Professor W H McCrea, Astronomy Centre, Physics Building, University of Sussex, Falmer, Brighton, BN1 9QH, England Encloses his final note to the Observatory, following L-B's reply, a copy of which is enclosed in case McCrea did not get one. Gold agrees with what McCrea said. L-B may have a point that some textbooks say the wrong thing; Gold does not know about that. Gold thinks this correspondence will be educative to many readers. 17 October 1978
