Is confident that by summer his sweeps will all be reduced and arranged in three catalogs for JH's Cape Results.
Met Friedrich Bessel at the Manchester B.A.A.S. meeting; invited him to Collingwood, where he expects Bessel in a few days. Enclosed with the letter a specimen of a new photographic process called 'Chrysotype.' Marvels at traveling from Hawkhurst to Manchester round trip (420 miles) in under 23 hours!
Reports the erection of an obelisk at Feldhausen to commemorate the site of JH's 20-ft. reflector. Back at Cape Town, Thomas Maclear is measuring N. L. Lacaille's Arc of the Meridian. JH received the Prussian Order of Merit.
JH finished his catalog of stars for his Cape Results; hopes to be finished with his nebulae and double star catalogs soon.
Assures CH that he has preserved everything that she ever wrote to JH or that he found in William Herschel's library.
Reports the birth of JH's 9th child, Mathilda Rose Herschel.
Wishes CH a happy 96th birthday. Reports that when Margaret Herschel's brother John Stewart was in Egypt, he saw a comet. JH remarks that 'there seems to be no end of the comets.'
JH expresses pleasure in receiving and reading extracts from CH's biography. Expects to begin printing his Cape Results by Christmas. In finalizing his Cape Results, JH has found that several Southern double stars moved in the five-year span of his observations.
Reports that Biela's Comet split into two comets; JH has observed it several times. 30-40 pages of JH's Cape Results have been printed.
JH is working hard on his Cape Results.
JH expects that CH has received the copy of his Cape Results that he sent recently.
Sweeping progressing quickly; has used the 20-ft. reflecting telescope since February. Discovered two planetary nebulae. Studying Scorpio closely, as CH suggested; has found gorgeous globular clusters there. The equatorial was erected recently.
Has decisively mapped Saturn's sixth satellite; doubts, however, that he will ever see the seventh. Asks CH to inform Friedrich Bessel of his observation.
[Postscript to a letter by Margaret Herschel:] JH notes that he has finished the reduction of the first 9 hours in Right Ascension of his southern nebulae and double stars.
Finished the reductions of all of the nebulae and double stars recorded at Cape Town; JH soon hopes to prepare for the publication of his Cape Results.
Studying the volcanoes of Auvergne; hopes to use his newly-created actinometer at the Puy de Dôme.
Received the first volume of Johann Pfaff's German translation of William Herschel's papers. Just completed a second catalog of double stars; review of nebulae going slowly. JH comments on his precise sweeps.
Hopes to send to CH a catalog of new double stars soon. JH is very disappointed with Johann Pfaff's German translation of William Herschel's papers.
Sending the Gold Medal awarded to CH by the Astronomical Society and also a pair of bracelets from his mother; will send the indexes later. Just erected James South's large equatorial.
JH played no role in the awarding of an Astronomical Society medal to CH. Sent to CH a few copies of JH's Light. His catalogs of double stars and nebulae are progressing well.
