Letter from Jose de Mendoza Rios, Brighton, to Sir Joseph Banks Rios now regrets that he is unable to wait upon Banks as severe illness in his family has called him from London; he regrets that permision to use some of his Tables for Nautical Astronomy would affect his interest as much as the alienation of the whole; he offers to part with the copyright of his work for the sum of £1500. 24 November 1813
