Thanks JH for sending a copy of his Prelim. Discourse; notes that it has been translated into German from a French translation. Laments that she is 'decaying.'
Received news from the Duke of Cambridge of JH's appointment to the Royal Hanoverian Guelphic Order.
Losing her strength and eyesight. Describes a conversation with the Duke and Duchess of Cambridge.
Sends to CH his new book, Prelim. Discourse. Writes that he 'took little part in the proceedings about the Royal Society. Under any circumstances I would not have held the office of President more than a year and should have felt it a grievous evil to have held it at all.'
JH awarded the Guelphic Order of Knighthood by King William IV, an honor earlier bestowed on William Herschel.
Regrets that William Herschel could not see JH finish WH's catalogue of double stars; thrilled that JH has revived WH's name.
Observations on [double] stars. Congratulations [on birth of Isabella Herschel].
