Writes to thank WR for the paper on the thermodynamic theory of waves he sent; JH is too ill to respond or even to deal with the analysis in the paper. Nonetheless, JH does make some suggestions for WR's consideration.

The Sir John Herschel Collection
The preparation of the print Calendar of the Correspondence of Sir John Herschel (Michael J. Crowe ed., David R. Dyck and James J. Kevin assoc. eds, Cambridge, England: Cambridge Univ. Press, 1998, viii + 828 pp) which was funded by the National Science Foundation, took ten years. It was accomplished by a team of seventeen professors, visiting scholars, graduate students, advanced undergraduates, and staff working at the University of Notre Dame.
The first online version of Calendar was created in 2009 by Dr Marvin Bolt and Steven Lucy, working at the Webster Institute of the Adler Planetarium, and it is that data that has now been reformatted for incorporation into Ɛpsilon.
Further information about Herschel, his correspondence, and the editorial method is available online here: http://historydb.adlerplanetarium.org/herschel/?p=intro
No texts of Herschel’s letters are currently available through Ɛpsilon.

Requests publication of a notice of the recalculation by H. J. R. Petersen of the Gaussian constants of terrestrial magnetism.
Has sent a note to Nature stating the details of the grant paid by the B.A.A.S. to H. J. R. Petersen for magnetic observations.
Comments on use of 'air' lens rather than glass in some circumstances.
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].
