Describes JH's location at the Cape and his observational sweeps, lists nebulae and double stars, as well as comet and eclipse observations. [Letter finished on 1835-3-5.]
Compares magnitudes for some specific stars and then comments more generally on that question; JH believes he will no longer be able to observe in winter in England as he is too severely afflicted by rheumatism.
Requests that HS look for a shipment of a clock and send it on to J. J. Littrow, and inform the maker in London, Robert Molyneux, that HS has done this. JH sends along John Pond's catalogue of star position differences.
Thanks for honor conferred by Astronomical Society. Mentions [F. W.] Bessel's paper on the 4th satellite of Saturn. Calculated tables of apparent places of 45 stars, which HS plans to publish annually.
Sends invitation to participate in an astronomical journal. Asks JH to forward letter to [F.] Fallows at the Cape of Good Hope. Mentions [Thomas] Young's plans to travel. Requests that JH forward letters to [W. H.] Wollaston, [John] Brinkley, [David] Brewster, and [Henry] Kater. Encloses announcement of founding of Astronomische Abhandlungen and of Astronomische Nachrichten.
Thanks for forwarding notice on journal to [F.] Fallows. Hopes to use the longitudinal differences of English observations to improve observations.
[J. W. A.] Pfaff plans to publish a translation and edition of all William Herschel's papers. Requests a catalogue of those papers and permission to publish a biography of his later years.
Thanks for forwarded essay on physical astronomy. Remarks about method for precisely determining the power of a telescope. Has [C. L.] Harding's celestial atlas. Wanted to dedicate book to Astronomical Society, but asks privately whether permission is necessary.
Will forward Astronomische Nachrichten to JH and Astronomical Society. Comments on quality of [Joseph] Fraunhofer's micrometer, which has only the wires illuminated. [C. F.] Gauss uses a theodolite to determine the angle of the telescope.
Announces a new step to all astronomers toward understanding the solar system due to work of [Thomas] Clausen of the Altona observatory. Clausen recognized that the comet discovered by Biela was the same as that of 1805 and 1772. HS gives details of circumstances.
Sends news of a cholera epidemic to help JH make his summer plans. Mentions a number of new cases from Altona, Hamburg, and Berlin. Asks JH not to spread information.
Sends two bottles of Claret and a box to be forwarded for [Francis] Baily.
[Otto] Rosenberger has calculated perturbations of Halley's Comet by the inner planets. [Wilhelm] Beer and [J. H.] Mädler have a map of the moon and have located two moving spots on Jupiter. F. W. Bessel's assistant has reduced James Bradley's observation to constants of aberration and nutation.
Visits F. W. Bessel in Berlin to discuss pendulum experiments. [C. A.] Steinheil invented a photometer to measure relative light of different stars.
Received JH's note from Belvedere Hotel. Mentions various arrangements regarding JH's European journey, including JH's planned visit to Wilhelm Olbers.
Unless other responsibilities interfere, HS will meet JH in Bremen.
In compliance with JH's request, HS did not go to Bremen to meet JH. Hopes JH will visit him in Altona and stay at his house.
Asks if he can publish the finding that the star in Argo is dimming in Astronomische Nachrichten. Questions whether barometric information should be in feet or yards. Asks JH about a publication that HS and [Alexander von] Humboldt are planning.
Forwards a request from C. F. Gauss for magnetic observations made in England.
Asks permission to use information from JH's letter in Astronomische Nachrichten. Believes [Alexander von] Humboldt can explain observational anomalies that JH notes.
