Letter from C [Charles] Pritchard, [The Grosvenor Hotel, Victoria Station, Pimlico - scored through], to Sir John [Frederick William Herschel] He hopes to call on Herschel on Monday for an hour. He is going to see his eldest son [Charles Bradley Pritchard] who has returned sick from Bombay [Mumbai]. He wishes to ask Herschel what he knows about [Johann Franz] Encke; Pritchard must do justice to his memory. He did know [Friedrich Georg Wilhelm von] Struve, thanks to Sir John and Lady Herschel, but he never met Encke. After working for six years for the [Royal Astronomical] Society, Pritchard has been made President. They gave the medal to [John Couch] Adams for his investigations into the acceleration of the Moon's mean motion, which he describes as a 'head-splitting brain turning subject', which [George Biddell] Airy has been wrestling with. 9 December 1865
