Thanking him for his paper on heat developed in combination of acids and bases. Commenting on the various makes of calorimeters.

Note to accompany a translation of one of GE's writings; also comments on the 'reform' of the German language.
Comments on spelling reform being attempted in Germany and the United States, and being proposed in England.
Thanks RP for sending RP's Sun. Suggests a theory that the solar corona, rather than originating in the earth's atmosphere, is produced by reflection from meteoric dust. Informs RP that he has completed a catalogue of all observations of double stars.
Regarding patents, and quoting the results of experiments by foreigners without acknowledging the sources.
Replies to RP's objections to his theory of the solar corona. Informs RP that William Herschel's larger telescopes were used as front focus. Suggests explanation of his father's disconfirmed discovery of four additional Uranian moons.
Comments on the attitude of the French towards the Germans in light of the war.
Comments on sunspot activity.
Comments on R.S.L. acquiring Kew Observatory building for creation of magnetic observatory [see JG's 1871-2-13].
Mostly about how to deal with the implications of local attractions in geodetic surveying [see JH's 1870-11-17]; JH has had the mineral son John sent analyzed and sends the results. JH commiserates with daughter-in-law Mary's illness.
Thanks for, and comments on, some photographs of the solar corona.
Thanks TA for information on ice calorimetric work.
Admits that recent heliographs of the corona favor the eruption theory over JH's meteoric theory. Notes that this raises question of the nature of the photosphere. Cites recent results showing link between sunspot formation and terrestrial magnetic disturbances.
Needs address of [H. J. R.] Petersen of Kiel, to whom JH must send grant of £50 from B.A.A.S. for reduction of Gaussian constant. Gives address of G. A. Erman. JH's poor health.
Thanks WS for volunteering to forward B.A.A.S. grant to G. A. Erman while JH is ill.
Does not know what commitment of John Herschel (JH's son) would be for December 1871, but encourages GA to communicate with him [see GA's 1871-3-13].
Reiterates his congratulations to AQ for his work on statistics. Believes AQ will have many readers. Mentions that JH is now eighty years old.
More remarks relating to French/German relations [see JH's 1871-2-9]. Thanks EC for more poetry and an account of an earthquake she experienced. JH is in poor health.
No doubt he has received some of the money granted by the B.A.A.S. Has sent it all to GE as he did not know the address of H. J. R. Petersen. Unable to follow GE's scientific arguments. Require simplification.
Please clarify FW's request for testimonial from JH to assist FW in obtaining better appointment. JH does not know FW's capabilities and can testify only to good character of FW's family.
