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.
Encloses some specimens of photographs made by the use of chloride of gold and bichromate of potash. Comments on the process.
Outlines his domestic history. If JH knows of a suitable position vacant that may suit RH he would be pleased to hear of it. Cannot understand JH's lack of success with the photographic process RH uses. His own book is printed and is waiting for an engraving. Will send him a copy.
Is most grateful for JH's offer of assistance for one of his sons. Suggests the second one would be most suitable. Is certain Sir Charles Lemon, their president, would support him.
Charles Lemon has communicated to him the result of an application made by JH to Prince Albert on behalf of one of RH's children. Is deeply grateful for his assistance.
Sends a copy of G. R. Anson's letter to Charles Lemon regarding a scholarship for one of RH's children. Is deeply grateful to JH for his nomination and support.
A letter of even greater urgency about the very serious state of health of Madame Gerlach, the aunt of NS [see JH's 1843-10-20]. Madame Gerlach is living with the Herschels [as tutor? or governess?].
Sending some specimens of photographs by a new process that he thinks is unrivalled for simplicity and sensibility. Comments on his method. Has sent an account of another curious process to the P.M. His little boy will go to Christ's Hospital in July or September.
Has just returned from London where he has taken his son, ready to go to Christ's Hospital. Would have called on JH but believed he was not at Collingwood. Hopes to meet him at York. Comment on his recent photographic work. Would like to obtain a position in London.
Returns his interesting specimens. Has read his communication in the Physical and Chemical sections. Regarding the use of certain terms. Had long discussion with W. H. Fox Talbot on matters of Light. Has been offered a position at the Birmingham Institution. Is there any chance of obtaining a position in London?
Received the enclosed silver plate on which is an impression made by the moon; has he any comments. Has been experimenting with solution of bichromate of potash and sulphate of copper exposed to actinic influence. Has been giving his attention to ferrotypes recently.
Has applied to the Council for the position and Michael Faraday has promised him support. Has also heard of a forthcoming vacancy in the Museum of Economic Geology. Is undecided which to apply for and would welcome JH's views.
Has been appointed keeper of Mining records at the Museum of Economic Geology. Hopes to meet him personally and thank him for his assistance.
Sends an analysis of the salts he sent him at Cambridge.
Has just been showing Michael Faraday some of his experiments on the influence of magnetism of bodies slowly precipitating; comments on this and will be pleased to carry out any experiments for JH.
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?
As JH has not heard from NS, he has arranged for Madame Gerlach to stay with Mrs. Mason, now living in part of JH's former residence at Slough. But under no circumstances can Madame Gerlach return to her duties with JH's family.
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.
Is desirous of procuring impressions of prismatic spectra from all parts of the globe. These should show the chemical influence of the solar rays. The B.A.A.S. may be able to help or Colonel Edward Sabine. Can JH use his influence?
