About travel plans once he recovers his health.
A notice of meeting of the R.S.L. committee to improve glass.
Acknowledging the letter of 25 Nov. informing GM that he has been elected to the R.S.L. Will attend at the earliest opportunity to be admitted.
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.
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.
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.
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.
Sends JH the results of the analyses of several specimens of experimental glass.
Regarding [William?] French and G. B. Airy. Will breakfast with JH on Sunday. Going to Cambridge on Monday and would like his company.
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.
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.
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?
[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.
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.
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.
Is waiting to recover his health before he leaves for Scotland.
