Cruel illness has kept him from work for a while. Just finished Histoire des sciences mathématique et physique chez les belges. AQ's son works with proper motion, double and multiple stars, and absolute positions.

Sent information on meteor spotted in Belgium and in Germany. Has heard differing opinions on heights of meteors. Talks about statistics of population.

Thanks for article by JH's son Alexander Herschel on meteors. Has printed it in Bulletin of the academy.

Has received letter on meteors of 1868-8-10. Map was very interesting. Is going to Berlin for congress on statistics. Discusses phenomena of 1854. Asks for JH's opinion on whether meteors are terrestrial in origin.

Received documents from JH just before leaving for Berlin. Discussed periodic stars in Berlin. Stayed in Berlin longer than expected, but was received well by old friends.

Lists works JH should have received. Asks JH to take another look in his library. Has received more on meteors. Sees no objection to a higher terrestrial atmosphere. Will send Histoire des sciences mathématique et physique chez les belges.

Sends JH other copies of works not received. Also work on international statistics. Has found out that JH has written an article on probability. Would like to use it.

Was in Paris when JH's letter arrived. Will print JH's article. Asks if there are changes to be made. Discusses future project Physique sociale, which will include theory of probability applied to ethics and political science.

Has received works on meteors. Has been working for years with [H. A.] Newton on getting help from observatories in southern hemisphere on meteors. Resumes work on Physique sociale.

Apologizes if AQ has missed answering one of JH's letters. Talks about meteorology of Belgium worked on over 30 years. Wants JH's photo for his work on statistics. Congratulates JH on his son's good work. Has received work from Collingwood and would love to know author.

Expresses good wishes for JH. Talks about aging. Notes JH's interest in poetry. Thanks for 'Of the Estimation of Skill in Targetshooting.' Has given it to [Edouard] Mailley for translation and printing in annual bulletin of Brussels observatory. Asks if JH wishes to be named as author.

Discusses coming year. Asks JH how to deal with JH's review [of AQ's Lettres sur la théorie des probabilités]. Talks about his friend [Michel] Chasles. Also about AQ's son. Mentions JH's translation of [J. C. F. von] Schiller's 'Spaziergang.'

Offers translation of JH's review [of AQ's Lettres sur la théorie des probabilités] to look over. Has been updating his own text to reflect progress.

Sends first pages of JH's work on theory of probability. Asks for modifications.

Thanks for comments on AQ's Sur l'homme moyen. Translator of JH's work is too timid to allow himself to be known, but appreciates JH's compliments. Says practical statistics has progressed whereas philosophical statistics remains stationary.

Thanks for proofed pages. Received Astronomische Beobachtungen auf der Sternwarte zu Bonn. Finished determining by electric means the different observational longitudes of Leiden and Brussels.

Announces first volume of Physique sociale will appear soon. Discusses humans and law of nature. Says science is neglected in France.

Obtained and sent JH 2 copies of Physique sociale. Thanks JH for observations but they are too scientific for his lectures.

Is trying to get JH 2 copies of Physique sociale. Discusses additions. Addresses JH's comments concerning power of a supreme being. Sends 19th volume of annals of observatory and AQ's work on international congress on statistics.

Thanks JH for his positive judgement of his work. Mentions that [François] Moigno could only say that it was anti-religious. Another work on statistics has emerged: Versuch einer Sozialethik, 2nd. vol., by Alexander von Ochingen. In few days leaves for international conference on statistics.
