Received JH's translation of fourth book of Iliad. Will return it with comments in a few days. Attended two or three excellent lectures by JH's son. HH needs to balance mental efforts with more physical activity.

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.
Would like some contributions from JH for the Churchman's Family Magazine.
Is pleased that JH has used Lady Callcott's account of the 1822 earthquake at Valparaiso. She was pained by the doubts of her accuracy by G. B. Greenough.
After receiving testimonials of the highest order he has appointed [Albert?] Marth to be his assistant. Encloses some observations of nebulae. If JH's sons are visiting Malta he would be pleased to see them.
Has been reading his work on volcanoes and earthquakes ['About Volcanoes and Earthquakes'] with interest. Regarding his own health.
Is grateful for his reply. Where can he find a statement of Isaac Newton regarding the relationship between colors and music?

Official receipt for copy of JH's The Telescope (1861) by library at Smithsonian Institution.
Received his letter and comments with pleasure. Asks some questions on photographic experiments.
Preparing classified index of observatory journals, but information will not be accurate enough to help JH. G. J. Stoney is too busy to help remeasure nebulae positions.
In GA's absence, ES reports on the state of completion of the final copy of the nebula catalogue [see JH's 1863-1-13].
Gives details of calculations [for JH's catalogue of nebulae]. Three more weeks of work needed.
Has read JH's publication on volcanoes ['About Volcanoes and Earthquakes']. Comments on the formation of rocks and the creation of the world.
