Is grateful for his courteous criticism of his research into Aboriginal dialects. Casts have been made of the heads of several of the aborigines.
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.

Acknowledges receipt by Harvard College Observatory of JH's 'A Synopsis of all Sir William Herschel's Micrometrical Measurements...' (1867).
Has sent a copy of his book on color to the R.S.L. library and would be glad of JH's comments on it.
Delayed answering JH's letter. Describes new baby son [Thomas?]. Thanks Margaret Brodie Herschel for note.
Thanks for the gift of the paper on color. Comments on this and the subject in general.
Thanks HR for sending HR's book on spectrum analysis [Spectrum Analysis, 1869]. Praises that publication.
Thanks for paper on comets. Offers questions, problems to be resolved, particularly on termination of comet.
About an increase in sun spot activity.
Thanks for JH's suggestions on JT's outline of comet speculations. [G. B.] Airy, too, has replied. Includes more speculations on 'envelopes' and nucleus of comet.
'Great Comet of 1843' presents difficulties for JT's explanation of comets' tails [continuation of JH's 1869-5-28].
Is considering a new edition of Outlines Astr.[?] and wants to provide the latest determinations of the periods of rotation of the planets.
Suggests experiments with regard to polarization and vaporization, and comets' tails.
Gives information on the rotational periods of Mars, Jupiter, and Saturn [see JH's 1869-5-30].
Has written to Lieut. John Herschel suggesting points on which solar observations might be valuable. Is pleased he has seen the bright lines. Saw some bright lines in the middle of the sun's disk.
Is grateful for the paper and comments. Has referred to JH's papers many times in the lectures he has given. Hopes to produce a cheap book on color.
Asks JH for copies of both Latin and English translations of Schiller's 'Walk'.
Thanks for his kind note and his tracts on Atoms and Forces. Thinks J. S. Mill's Logic is dangerous. Hopes he will read his book thoroughly and not be too critical of his astronomy.
In response to JH's comments on JT's explanation of comets says faintness of head and nucleus does not indicate non-existence; eye may not see all. Experiments with polarized light produce 'gorgeous' 'residual blue.'
Will JH be able to attend the forthcoming meeting of the Board of Visitors? If not would he inform the Board of his intentions.
Note to accompany the reported observations of JH's son John.
