Wishes JH a happy birthday. Finished the catalogue of 2500 nebulae.
Completing the catalogue of 2500 nebulae. Impressed with a French biography of William Herschel, although CH notes a few occasions where 'too great a stress is laid on the assistance of others.'
Her social life is rather boring at the moment because CH is busy caring for her sick brother Dietrich.
Recovering from a prolonged illness. Discusses parallax. JH reports that he now is very skilled at sweeping with the 20-ft reflecting telescope.
Informs CH of his gold medal from the French Academy of Sciences for JH's and James South's paper on double stars. Finds CH's catalogue of nebulae in zones very useful. Heard about Johann Pfaff's death. James Grahame may be moving to Göttingen.
Studied 659 double stars; JH is confident that his work proves his father's conclusions. Now plans to study nebulae.
Compliments JH on work as Secretary of the Astronomical Society and for keeping the scientists of Europe informed of discoveries made in England. Finds that GS needs permission from Italian government to be a member of the R.S.L.; expects this will not be difficult.
Thanking him for his friendly reception when in Italy. Is sending GA journals and pamphlets likely to be of interest to him. Regarding various papers on the electrization of mercury. Please send details of Giuseppe Bianchi's barometer.

Concerning recent works and discussions connected with longitude.
Has returned to Brest, and found his letter. Is honored to correspond with JH. Further regarding pendulum observations.
Is sending him a paper dealing with the measurement of the arc of the meridian between Greenwich and Paris. Further observations along the coast by Lieut. C. L. Largeteau.
