RS had intended to be in Cambridge now but he finds that lectures do not begin as soon as he thought. Further, 'Tate's daughters are in town and I must ask them and help to entertain them'. He will be in Cambridge around about the 20th unless Haviland's lectures begin earlier. RS finds 'that Young [Thomas Young] has treated the Prof.'s [George Airy] speculations upon the Solar tables and their errors somewhat cavalierly. I trust he has got the wrong two by the ear and that Airy who has a back to his head will teach the [?] that errors so serious ought to be and must be immediately investigated and remedied. Happily A. appears to have no disposition to yield and if he is resolute these supercilious [?] must change their notes'.
Royal Observatory Greenwich - Answers WW's queries: when Newton's 'analysis is carried to perfection (i.e. so as to shew Fraunhoffer's lines), it has certainly developed original properties of light... Their existence in the diffraction spectrum tends most strikingly to confirm this. - You may also say that persons who have tried the experiments with great care do not believe in [David] Brewster's changes of colour. - The changes of colour are certainly the only source of his objections'. The French have always associated Thomas Young with the discovery of the undulating theory of light.
If WW has not got the time to write Thomas Young's biography, has he asked George Peacock whether he would be interested in the task?
Eliza Young would like WW to consider writing a biography of Thomas Young. If not who would he recommend - Mr. Drinkwater?
Trinity College - When will RJ be coming to vote for Cavendish [William Cavendish], could he also bring any of his work on wages so they can concoct an application to the Cambridge press syndicate? WW has had another letter from Mrs Young which appears to authorize him to negotiate with Peacock [George Peacock to work on a biography of Thomas Young].
