Contacts with Alexis Bouvard and P. S. Laplace. Criticizes an astronomical paper by [Robert] Woodhouse.

Comments negatively on an astronomical paper by Robert Woodhouse. [J. F. A.] Gambert in Marseille has reportedly discovered a comet. Details on the medal to be awarded by the Academy to JH and JS. If, as reported, Wilhelm Struve has come to England, invite him to visit JS in Paris.

JS has received the medals awarded JS and JH by the French Academy for their paper on double stars. Reports on his new work on double stars and his observations of [J. F. A.] Gambert's comet.

Laments the difficulty of transmitting publications between Paris and London. On arrangements to get JH's Lalande Prize medal to JH. JS's recent observations and contacts with Parisian scientists.

On his contacts with French scientists and on their praise for the JH's and JS's catalogue of double stars. Suggests that JH, beset by excessive commitments, cease to devote time to seeing JS's publications through the press. Comments on the personal cost to JS of his devotion to double stars. Remarks on JH's efforts to measure the difference in longitude between the Greenwich and Paris observatories. Data on double stars.

JH's attempts with Edward Sabine to measure the difference in longitude between Greenwich and the Paris Observatory. Supplies, for Alexander von Humboldt, JH's measurement of Mount Etna's height. Gives message for François Arago concerning paper on magnetism published by JH and Charles Babbage.

Comments on various errors detected in the catalogue of double stars published by JH and JS. Scientific affairs in Paris in relation to Alexander von Humboldt, François Arago, P. S. Laplace, and others. Various cometary and stellar observations of JS.

Asks JS to check over and forward to Astronomische Nachrichten JH's paper ['Letter on Fraunhofer's Claims for the Inferiority of Reflecting as Compared to Refracting Telescopes'], which paper calls attentions to errors in the catalogue of double stars published by JS and JH.

Reports observing with J. N. Nicollet two comets. Observations of Encke's comet. Gives position of nebula to be observed by JH.

Reports his observations of a comet JS detected and also of Encke's comet. Pleased JH is recovering from illness.

Sorry JH is still sick. Will send JS's new double stars observations to JH for his comments and for publication.

Is sending his latest double stars observations to JH. Weather is making observation difficult. Will be in London in November; hopes to present paper at R.S.L.

Has been delayed in France, but is sending large collection of double star observations for JH's comments and analysis. Has dismantled JS's observatory in Passy as part of return of JS to England. Comments on P. S. Laplace.

R.S.L. Council will meet 17 Nov. to discuss awarding its Copley medal; hence JS's paper, to be presented to R.S.L. later that day, cannot be considered for the award. Other matters have prevented JH from preparing annotations of JS's latest paper on double stars.

Looked for JS to talk with him about the secretaryship of the R.S.L., specifically discussing Charles Babbage's position. JH would prefer to have JS nominate Babbage.

Urges JS not to insist on a minor point of dispute about the title of a prospective member. JH feels it is inappropriate and will simply reflect against Charles Babbage, who proposed this person for membership.

Attended inquest regarding the 'calamitous' fate of [James] Grahame. Is sending JH inquest report, which contains important information.

Thanks JS for materials sent. Laments the decline of science in England. Believes decline has deep roots.

Attended meeting of the Astronomical Society and made observations of Saturn. Invites JH to dinner party. Activities at the Board of Longitude. Contacts with French scientists.

Thanks JH for information on JH's detection of Encke's Comet. JS's contacts with various astronomers, including Peter Barlow, John Pond, and François Arago.
