Discusses his diagram of planetary distances to the sun and earth. Will soon have autographs of sun showing the 'change-up' of a spot.

Thanks JH for the Dante translation. He and Charles Jenyns commend the translation. Sends a translation [into Latin] of [S. T. Coleridge's] 'Genevieve' for JH's comments.

Discusses the great reflector at Lord Rosse's in Ireland. Will send solar autographs JH requested. Thanks JH for the hints about the Julian Calendar.

Sent JH's remarks to Mr. Titterton at Ely. Will endeavor to maintain accuracy. The remarks about Jupiter's action are contrary to the general consensus that planets in opposition close up spots.

Thanks JH for saving her from publishing a fault-filled book. Describes eruptions of Vesuvius. Agnes [Greig] enjoyed visiting the Herschels. MS wishes she could see them again.

Congratulations on fine Dante translation. Met [John] Tyndall and enjoyed his company. Has made several changes in her book [Molecular and Microscopic Science]. Is 'quite well for her age.'

Congratulations on marriage of JH's daughter [Amelia]. Is writing her autobiography. Interested in solar eclipses, and says more will be known through photography and spectrum analysis.

Has worked much on revision of his Physique sociale. Asks for JH's changes to JH's review in Edinburgh Review. Puts translation at JH's disposal.

Apologizes for not writing. Has devoted all his time to Physique sociale. Has just finished last page.

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.

Their mutual friend James Sivewright had given ES plan for boat swing to combat Lady Sullivan's seasickness. Having sold boat in which swing was built, but planning to sail to Mediterranean, ES hopes JH will send another copy of plan.

Is losing position as Royal Mint messenger, which JH had helped him obtain. Asks JH to tell Mint Master that position was intended as permanent.

Is studying vesicles. JH's son [Alexander] may yet get Royal School of Mines appointment.

Thanks JH for sending plan for swinging cot to prevent seasickness [see ES's [1868]-11-28] and asks for more information.

Thanks JH for sending plan of swing to counteract seasickness. This will enable his long suffering friend Lady Sullivan to escape hay fever by going to sea but without thereby being beset by seasickness.

Regrets that JH declines offer [see AS's 1868-10-30] to publish series of papers in Good Words. Hopes JH will nevertheless occasionally send short papers.
