Comments on De La Rue's speech on awarding Gold Medal of RAS to JCA. Whether a quotation from Herschel should be included. Whether LeVerrier should be mentioned in light of his and Delaunay's part in the controversy over the secular variation of the moon's mean motion. Accuracy of Hansen's and Plana's theories. Encloses copy of Delaunay's letter.

See 36/16/2 for French translation. Acknowledgement of offer of corresponding membership of [French] Academy of Sciences. Personal thanks to CD for his influence.

See 36/16/3 for French translation. Pleased that CD's value of Secular acceleration of Moon's mean motion agrees with JCA's. Has carried the work further since publication and has a better method: sets out some more results for CD's use and for him to communicate to the [French] Academy of Sciences on JCA's behalf. Acknowledges copies of papers received from CD.

See 36/17/1 for French translation. Acknowledgement of copy of paper on acceleration of the moon sent by CD. JCA's latest equation. Death of JCA's father.

See 36/17/2 for French translation. JCA's latest equation for secular acceleration of moon's mean motion.

See 36/17/3 for French translation. CD's letter verified JCA's coefficients in expression of secular acceleration of moon's mean motion. JCA has discovered error and corrected it, in his own work.

Acknowledgement of CD's complete formula for the secular acceleration of the moon. Comparison of formula with Plana's mistakes.

See 36/18/1 for French translation. Acknowledgement of copies of CD's replies to LeVerrier's attacks on his theory of the moon. Nature of LeVerrier, Hansen's and Plana's errors. M. de Pontecoulant's letter in Monthly Notices of RAS. See 16/17/2 for another version of this letter.
