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.
Thanks for his letter. His barometer is not intended as a mountain one. Though a slight error does appear now and then it is no worse than other barometers, excepting that at the R.S.L. Would like JH to communicate the drawing and description to the R.S.L.
Is applying for the position of Radcliffe Observer in the place of S. J. Rigaud and would like to use JH's opinion of MJ's star catalogue he used at the Cape.
Was grateful for JH's communication and is pleased his catalogue met JH's approval.
The belladonna JH gave him is throwing up vigorous leaves. Has a scheme for making it leaf and flower in the same season. Has some ingenious machines to show JH when he calls, which may be useful to JH.
Whewell and RJ plan to visit South Wales and would like to stop at Slough en route.
Will be leaving London on 16 July and would like to meet JH at some convenient time to carry out H. C. Oersted's commission.
Sending magnetic observations. Would like a description of A. F. Osler's Anemometer. Regarding the periodical return of the magnetic disturbances on 18 Oct.
Thanks for the gift of the meteorite to the British Museum; an official letter of thanks will follow later.
Too ill to attend a demonstration by CW of one of CW's instruments [?].
Is greatly obliged for the present of flowers. Has introduced another Herschellia into the world as he has used the name for a Disa.
Will be pleased to examine the dried plants. Send them to the Horticultural Society's Garden, Turnham Green.
Has opened the box of dried specimens, but they are unsuitable for his purpose as they are not flat. Suggests that King's College or University College may be a more suitable home for them.
Is working on horticultural considerations of Cape plants and would welcome information on the temperature just below the surface of the soil in relation to the temperature of the air.
Was pleased to hear of the success of JH's exertions. Comments on the instruments required. Thanks for his communication on the copper ring; will try it with the bifilar. W. H. F. Talbot talks of applying the photographic method to meteorological and magnetical instruments. Encloses a paper.
Has ordered the instruments for the Van Diemen's Land observatory. Is uncertain regarding the third magnetometer; T. C. Robinson's has not yet been tested. Will order a dip circle from Paris.
Has just had a letter from C. F. Gauss regarding the hours for observations; comments on this.
Finds that he misunderstood Edward Sabine's statement and may have misled JH. Comments on the observations desired from the Antarctic Expedition.
Has he succeeded in obtaining a Daguerrotype for J. C. Ross? Thinks one or two would be desirable. Has got one himself and obtained good results. Two of his family are ill, which brings him to town. Hears that JH has got colors, which is a great step.
Please accept her heartfelt thanks for his kindness.
Responds positively to HL's 1839-4-17, and adds some additional comments.
