Comments on the quality of some of the double star observations in print.
Gratitude for JH's generous testimonial on RM's behalf.
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.
Thanks JH for information regarding Henry Brougham [see ES's 1868-9-29 & 1868-10-8]. Also for comment on polarization of aurora. Encloses Captain [John?] Hay's letter, but not plate.
Thanks JH for his pamphlet on musical scales.
Discusses [William] Sharpey's view of JH's opinion of [Henry] Brougham's optical writings. Asks for JH's advice on presenting meteorological observations. On observations of an eclipse.
Much obliged for his kind notes on sunspots; there has been a wonderful variety lately. Will make a study of the Julian dates. Can see the Crystal Palace fireworks splendidly from his house.
Was pleased to receive JH's translation of Dante. Wished he lived near enough to pay them a visit.
Further regarding the theory of sound.
Is preparing a sketch of Sir John Lubbock for a weekly, and would be glad of JH's opinion regarding Lubbock as a man of science and his advanced political views.
Subscriptions for Sinai survey fund are nearly complete. Survey party will embark for Alexandria aboard Ripon on 24 Oct. Will send account books to JH and R. I. Murchison. Will not need JH's astronomical instrument.
Is grateful for his article on musical scales. Queries regarding musical sounds. Has had to leave his old abode due to building operations.
R. I. Murchison has forwarded JH's letter about the noises at Nakkus in Sinai. Has heard the noises several times and thinks they are caused by the movement of sand. There is much static electricity in sand.
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 for his article on musical scales. Will read it later when he has time. Comments on the system of equal temperament. Will send some of his own papers later.
Hopes that JH will contribute series of papers under heading, 'A Life's Retrospect in Science,' from various periods of JH's career, for publication in Good Words.
