Apologizes for not writing often. Has been ill. 'Moderate' use of 'Coca de Peru' [cocaine] helps. Is working on a 'General Catalogue of double stars reduced to 1830.0.' Acknowledges works received.

Inconceivable that JH merely writes 'J'accepte' (I accept) in response to the great honor AQ bestows upon him by dedicating his book to JH. Congratulates AQ on his 'fresh contribution to statistical knowledge.' Has just completed his catalogue of approximately 10,000 double and multiple stars.

Thanks JH for writing. Complains of obstacles to his work. Happy to see JH recognizes work begun by Blaise Pascal and continued by famed mathematicians. Asks JH to respond to AQ's wish to dedicate his book [L'Anthropométric] to JH with only one word: 'J'accepte.'

Asks where AQ can procure best instruments in England. Desires to view the interiors of English observatories. Wishes to have [Alexis] Bouvard, who is in need of a change of scene after [P. S.] Laplace's death, accompany him. Sees translations of English scientific works, especially JH's, as a desirable project.

Has missed seeing JH, who must be in the countryside with [Charles] Babbage. Hopes to see JH and ask advice for observatory at Brussels.

Translation of JH's article Light begun. Publisher is in Paris. Gives name of collaborator as [P. F.] Verhulst. Has heard of others translating JH's work. As director of Brussels observatory, AQ needs best works of astronomy. Would JH help?

Regrets tremendously not being home when JH visited. Wishes to present himself at JH's hotel this evening. Would like to spend tomorrow together. Will discuss translation of Light.

Is pleased to write letter to [G. P.] Dandelin for JH. JH should visit Mr. Van Rees at Liege, for which AQ will also write a letter of introduction. Nevertheless AQ believes JH's name suffices as introduction. If JH visits Namur, he should see the governor of the province, Mr. D'Omolius[?].

Has just received invitation. Regrets delaying JH's dinner. AQ is in the countryside. Asks to be allowed to visit toward the end of the dinner.

Requests JH visit Edward Troughton and the instruments.

Sends works for JH, the Astronomical Society, and several members. Worries about [P. F.] Verhulst. Asks for JH's recent observations. Has spent much time lately on the human laws. Thanks JH for seeing Edward Troughton and instruments. Has just heard that his friend Alexis Bouvard, who was like a father, is seriously ill.

Concerned about payment for instruments. Has read in newspaper that JH is preparing to study the southern hemisphere. Asks to keep in touch. Will soon go to Paris for transit instrument and another publisher for the translation of JH's work. Problems on account of Revolution.
