'Messrs. [Apsley] Pellatt and Green' will fill the pots on Monday. JH will attend. Asks correspondent to attend also. Has sent for Michael Faraday's approval a formula for making [the glass].

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.
Ask Charles Babbage to send tables of logarithms to TY, who will compare them to [Brook] Taylor's. Bets that five errors will be found. Did JH order mountain barometer from [J. F.] Newman? Will inquire about [W. E.] Parry's instruments. Admiralty, not us, should order sextants.
Richard Copeland has received such instruments as the Board thought he should have. A mountain barometer seems extravagant for his duties. If JH thinks a camera lucida is necessary, one can be supplied.
No summary available.
Sends JH the results of the analyses of several specimens of experimental glass.
Questions JH's conclusion that Board of Longitude has power to interfere in Admiralty operations. Disagrees that Nautical Almanac errors are serious. Compares them to tables of Charles Hutton, F. X. von Zach, and H. C. Schumacher. When will TY receive Charles Babbage's table?
Encloses note from Sir John Barrow refusing scientific instruments and objecting to using barometers. Supplying cameras and sextants to Admiralty's marine survey is not interference by Board of Longitude. Sent JH's expenses to Edward Sabine; has no further word on subject. Encloses Mr. Stewart's note about damages at Wrotham.
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.
No summary available.
Agrees with JH regarding the glass. Suggests that a meeting would facilitate results. Suggests that the glass maker should make several pots for the experiments.
[Board of Longitude] must answer to Parliament, not to public opinion. Do not contest the system. Order pocket sextants; they and barometer will be sent to Captain [Richard] Copeland. Knows how JH feels about expenses sent to Edward Sabine, but please write receipt and send it to TY within week. Will write directly to Charles Babbage for tables.
An account of the rocket experiments and P. S. Laplace's letter will be left at the R.S.L. Finds in Laplace's letter encouragement for the corroboration regarding the measurement of latitudinal degrees. Dismisses Laplace's opinions that the climate of Spitzbergen is too unfavorable for experimentation and expounds on the many reasons to favor this town.
Thomas Young approved supplying [Richard] Copeland with two sextants and one mountain barometer.
A notice of meeting of the R.S.L. committee to improve glass.
Missed JH at the R.S.L. meeting. Has some experiments on which he seeks JH's opinion regarding presentation at the Society. Enclosing report.
Is very concerned because JH's recent letter did not comment on the arrival of GP's memoir [see GP's 1825-10-24]. Comments on printing and arrangements for copies.
About travel plans once he recovers his health.
Thanks profusely for two volumes of Astronomical Society's memoirs. Sends brochure containing two memoirs: one on eclipse of 1820, the other on two comets in 1823-24. Gives news of various acquaintances and friends.
Is waiting to recover his health before he leaves for Scotland.
