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.
A furnace for glass making is under construction at the Royal Institution.
Cites six journal articles relating to chemical separation of titanium and iron. Sent report to Henry Kater.
As MF will be unable to attend the next meeting of the Glass Committee, he sends JH the analysis of the glass produced in one experiment, emphasizing its consistency and high quality.
Sends JH the results of the analyses of several specimens of experimental glass.
Gratitude for receipt of JH's Cape Results. Congratulates Margaret Brodie Herschel for her part in it.
Regrets that Richard Taylor has printed his own paper in the P.M. before it appeared in the R.S.P.T. Explains the reason. Is examining various pieces of glass and will forward the results.
Agrees with JH regarding the glass. Suggests that a meeting would facilitate results. Suggests that the glass maker should make several pots for the experiments.
Sending a paper for the R.S.L. Humphry Davy does not approve entirely of his arguments. Would be pleased if JH would glance over it and then inform Davy that he has it.
Was grateful for JH's letter and detailed notes. Hopes he will attach a copy to the paper when he communicates it to the R.S.L.
Has just received his letter. Has had no opportunity of examining the iron. Several years ago he made some experiments on the alloys of lead and cast iron, but does not remember the results. Is surprised that no new metal has been found in meteorites.
Has found some errors in the printing of his paper. Sorry to hear that JH has been indisposed, but believes he is progressing.
Has been trying to see him, unsuccessfully, about the affairs of the Optical Glass Committee. Hopes that JH will not resign from the Committee now that he is no longer Secretary at the R.S.L.
The furnace is breaking away at the top, and he encloses Joshua Ramsay's estimate for its repair. Thinks the present a suitable time for the repairs. Would JH speak to the Council?
Has made a piece of glass 5" square, which George Dollond reports is good. Proposes making a furnace at the Royal Institution. Does JH have any objections?
Has received his letter introducing Dr. Robinson, but thinks that the latter is not a worthwhile person to know. Is pleased that JH likes his recent experiments. Owes a debt to JH's Prelim. Discourse.
Esteems it a great honor to receive JH's request. Has searched through all his papers but has a spare copy only of the Third series. Is thinking of reprinting the whole series in one volume.
Saturday's experiments have brought a severe inflammation of the eyes so has been unable to use the aerolite. Returns it, but will try some experiments later if JH sends it back.
As JH has tried many varnishes he wonders if he has ever tried shellac. Has tried it on specimens of brass. Many thanks for his invitation.
His letter was a great encouragement and pleasure. Comments on his own and JH's experiments with light and magnetism. Contemplates a further series of experiments but requests JH not to mention it. Is at Brighton for a rest.
Has received his letter and suggestions for the experiment. Has ordered the glass from Newman. Is very busy so may not be able to carry out the experiment for a week or more. JH must keep the results secret for the time being.
