Invites JH to meet H. C. Oersted, Henry Warburton, and Henry Kater at dinner next Wednesday.
Previous engagement prevents WW 'joining the early party.'
Unsure whether WW will be in town to dine with JH Monday.
Most correct mode of proceeding will be to suppress incorrect corrections and not to give credit to [T. I. M.?] Forster for inferences of [Peter?] Barlow or calculations of WW.
Board of Longitude will meet at TY's home on Saturday.
Sends papers for R.A.S. and A. J. Fresnel's papers. Modifies analogy of infinite pipes to clarify TY's hypothesis of three principal colors. Charles Babbage sent survey of Mont Cenis. Can JH find its barometrical observations?
Vol. 6 and 7 of F. W. Bessel's observations. Did DB receive JH's paper?
Sends paper.
Letter of introduction to Mr. Robison, son of Edinburgh professor. Thanks PL for sending JH books 11 and 12 of LP's Mécanique céleste. Hopes to see PL's 'perturbations of Ceres and [J. F.] Encke's Comet.' JH's and James South's work on double stars verified views PL once held. Hopes François Arago will publish observations of double stars.
J. J. von Littrow delighted with clock sent by M & C and commissions JH to order another for L. A. Fallon, director of Great Austrian Trigonometrical Survey. Describes modifications. Contact Littrow for further details.
Please forward biography of WH and a list of WH's papers to J. W. A. Pfaff, who plans to translate William Herschel's works into German.
Heard from H. C. Schumacher that JP plans to translate William Herschel's works into German. Sends five bound volumes, three papers, and list of papers printed in R.S.P.T. Promises to send biography of William Herschel when it is finished.
Sends packet of books and papers for delivery to J. W. A. Pfaff, copy of JH's 'Essay on Physical Astronomy,' and JH's and James South's work on double stars. Promises to send biographical notice of William Herschel. Astronomical Society received HS's 'Schreiben en Dr. Olbers.'
WS was elected associate of Astronomical Society. Distributed books as WS directed. Will send JH's and James South's observations of double stars when printed. Neither Thomas Young nor William Herschel received WS's Dorpat observations.
'Our micrometer screws' are not in error. F. G. W. Struve's star measurements using Josef Fraunhofer's repeating micrometer agree well with JH's. So error must be in HK's observations.
Discusses various apparent errors JS has been detecting in observing double stars with two different telescopes. Assures JH that no serious problems exist.
Reports on various observations of double stars that JS has made. Asks JH to check some of JS's results.
Reports on efforts to make measurements regarding 39 Boötes. Accepts JH's invitation for JS and wife to visit JH at Slough.
Discusses observations he had made of various stars, especially a star in Capricorn that William Herschel believed to be a gravitational double. Has observed 61 Cygni.
Discusses a paper by [Edward] Troughton and work that JH and JS were preparing. Remarks on observations of 61 Cygni and of Sigma Cassiopeia.
