Will distribute the prospectuses of LH's book as desired, but regrets he will be unable to subscribe for a copy himself as its price is too expensive for his means. Pleased to hear of his good health.

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.

RH's experiments are extremely interesting and deserve to be pursued. Comments on experiments made by Michael Faraday and others relating to the formation of crystals in a magnetic field and the effect such crystals have on polarized light.
Has been pursuing his magnetic experiments with crystals and will be publishing a memoir on them. Comments on these experiment. Is there a difference in the mass of the earth at the poles?
Is giving a series of lectures at the Collegiate Institution. Has made some interesting discoveries recently and has deposited a paper with Faraday for communication to the R.S.L. Comes to the conclusion that chemical action can be suspended by magnetic force. Comments on this.
Has often thought of the inactive condition of iron and has made some notes before he received JH's comments. Has overcome all JH's objections to the intrinsic difference in the two poles. Comments on some of these experiments.
Regarding Benjamin Peirce's Elementary Treatise on Sound. Can lend him his own copy if JH has no copy.
Has sent the book. Gives an outline of his own work and ideas he has for the improvement of the piano. Would like JH's comments.
Continues JH's defense of Laplace's writings on probabilities [see JH's 1845-12-22].
A note to accompany a working out in convenient form an example of Laplace's probability ideas. [Enclosure not found.]
Talks about considerations to be taken into account when building telescope specula, especially large ones.
Thanks for his kind letter. Congratulations on another addition to his family.
Hopes all his family are well. If JH proposes to attend the Trustees meeting of the British Museum on Saturday, will he breakfast with RI and Dr. T. R. Robinson of Armagh?
Questions related to JH's 1846-9-26 having been asked by RR, JH writes to answer these questions.
Is applying for the French Mastership at the Belfast Academy and would be pleased to receive a testimonial from JH. Is also inviting subscribers for a new work to be published later.
A long statement against a very nasty article in the Mechanics Magazine on the priority controversy surrounding the discovery of Neptune.
Has been carrying out a series of experiments with spiders immersed in acids and finds their bodies are not protected in any way. Has also been experimenting with elastic tissues to see if there is a change of temperature.
Has seen the seventh satellite of Saturn. Encloses diagrams and comments on them.
Was in error when in his last letter he stated he had seen the seventh satellite of Saturn; he has yet to see it.
Details of WL's observations of the seventh satellite of Saturn.
Details of WL's observations of a ring and satellite of U. J. J. Leverrier's planet.
