Letter from Thomas Gold to Dr Dieter Heymann, Ms Joan Shack, The Lunar Science Institute, 3303 NASA Road 1, Houston, Texas Asks them to look at and compare the enclosed two letters. If this represents an oversight please inform him by telephone, otherwise please withdraw Gold's name from the conference. Mr Gregory Williams from his department has an interest in attending, and he could present the discussion on layering and exposure. The discussion of evidence for surface transportation is under Gold's authorship, and he does not have anyone to delegate this to. 28 October 1974
