GB had great pleasure conveying WW's literary project to the library of the London Mechanics' Institution. GB was very impressed with WW's discussion of vapour and its relation to the atmosphere - 'a mighty 'watering machine''.
86 Chesterton Road, Cambridge. - Apologises for not replying sooner 'time does seem to go so quickly now!'. Glad to hear the news about [Bob Trevelyan's] library, and that she has found the librarian so amiable. Also good to hear about [George?] Birkbeck, of whom he knew nothing. Bad luck that both of her readers had laryngitis; does not know how he would get on if he could not read a great deal. Also sorry that Mary Fletcher could not come to visit because of her brother's illness. He is keeping well, though he cannot do many things he once could he is still 'as capable as ever of having good talks on philosophy'. Dorothy is also keeping well, though says she is starting to feel old. Encloses a letter from Bob to Desmond [MacCarthy], which Molly sent in a 'sheaf' of his letters to Desmond.
