Letter from Thomas Gold to Dr Arnold O Benz, Eidg. Sternwarte ETH, Schmeizbergstr. 25, 8006 Zurich, Switzerland Has had a second refusal from Jaeger and is planning to write a major part of the paper soon, and will then send it to him. There are no really serious objections in the referee's report. It will be better to write a paragraph in their paper about instabilities that can make the proton and a-velocities equal en route, even though they must have started out differently, If he can, send Gold a paragraph. Will write again as soon as he has something assembled. 7 May 1973
