Letter from Thomas Gold to Mr Roy Lincoln, Editorial Assistant, NATURE, MacMillan Journals Limited, Little Essex Street, London WC2R 3LF, England Thanks him for his letter of 22 February. Gold quite agrees that a charge should be made, since the publication in question is purely a financial proposition. Feels that the figure of £5 per column is reasonable, but if he felt that £10 was a better figure he would have Gold's support. The article is rather short, so not much is involved. 6 March 1974
