Thanks JH for criticism of manuscript. Sends revised introductory paragraph. Thanks him for kindness to Signore Capellini. Scientific interest in Italy grows as politics settle.
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.
Asks permission to print extract of JH's letter on heat spots of spectrum of rock salt sample. Hopes JH's son [Alexander] will speak at Royal Institution; JT would help with illustration. Wonders how blue color of water relates to sky color and polarization.
Thanks for a gift.
Will help JH or JH's son [Alexander], whose mind PS admires, in any way possible.
Will take into account JH's suggestions [see JH's 1863-2-13] and see where this leads.
Remarks on upcoming lecture of JH's son [Alexander], and on glacial movement.
Informs JH that his photographs of the moon's surface and diagrams of the sun's envelope were sent to the engraver.

Thanks JH upon receiving the essay for the Leeds Astronomical Society lecture series ['The Yard, the Pendulum, and the Metre, Considered in Reference to the Choice of a Standard of Length'].
Announces JH's essay, 'The Yard, the Pendulum, and the Metre' will be read to the Leeds Astronomical Society on 10 Oct. 1863.
Informs JH that the Leeds Astronomical Society will print 'The Yard, the Pendulum, and the Metre' the day after its presentation.
Notes reception of corrections to JH's 'The Yard, the Pendulum, and the Metre.' Will send JH 100 copies of the essay.
Warren de La Rue observes 'willow leaves' [mottling on solar surface]. Diagonal solar eyepiece works with great success. Praises de La Rue's work as having astounding accuracy.
Asks whether JT can reprint JH's letters on the British modular standard of length, which letters were published in the Athenaeum.
Suggests JH send copies of JH's letters from the Athenaeum to members of Parliament because JH has more influence than JT.
