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.
Has examined Edward Sabine's transit measurements; finds them unproblematic.
Has represented JS's interests as best JH can regarding JS's proposal. Describes himself as unskillful in such representations.
Defends Edward Sabine's transit observations, noting that JH supports them on practical rather than theoretical grounds.
Note to accompany the sending of a number of papers; comments on the orbits of double stars.
'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].
Writing in response to claims made by Josef Fraunhofer, discusses the relative merits of reflecting versus refracting telescopes. Adds comments on double star observations made by JH and James South.
Thanks for the copy of his paper and errata. Received a packet of specimens of glass, which he presumes came from MF. Regarding the specific gravity of some of the specimens. Comments on further experiments to be made.
Regrets that Richard Taylor has printed his own paper in the P.M. before it appeared in the R.S.P.T. Explains the reason. Is examining various pieces of glass and will forward the results.
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.
Has found some errors in the printing of his paper. Sorry to hear that JH has been indisposed, but believes he is progressing.
Copies of the Éloge, which JF sent, are still at the Customs house so he is unable to comment on it. A list of his father's works is to be found in the Index to the R.S.P.T. Gives a list of all the discoveries and inventions of his father.
Expressing the thanks of the Académie for JH's gift of Observations...on 380 Double and Triple Stars.
Is grateful for the information on JH's illustrious father. Was ill when the letter arrived so hopes he will be excused for his belated reply.
Election to the Astronomical Society.
Unable to call on him as his mother wishes to return home directly. Edward Sabine has not returned yet. Outlines some of the difficulties Sabine is experiencing. Premature to judge results at the moment.
Comments on JH's mother's health, some communication from Greenwich, and the weather.
Query regarding the diagrams in one of JH's articles in R.S.P.T. Has purchased one of the compound lenses on JH's recommendation, and relates some experiments with it. Would be pleased for JH to call at his house.
