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.
