Sends copy of G. F. J. A. von Auwers's catalog of JH's and William Herschel's nebulae. Observatory has another copy. Notes odd lines seen in 'Refraction Spectra of 11 stars.'
Refraction spectra of six stars exhibit lines corresponding with 'Solar Line F.'
Expect some errors in calculations of positions for JH's catalogue of nebulae. Suggestions on format.
Is grateful for his reply and anything may be quoted from his works. JH's Prelim. Discourse is just the work for the general public and should whet the appetite for more.
Comments on family health; asks AD if he has read James Challis on the topics of the ether and of zodiacal light.
Apologizes for JH's further troubles with trust fund for CB's sister [Mary Anne Hollier], whose three sons are selling off their inheritances. Solicitor Charles Few will take care of legal issues. Not likely that JH can resign as trustee.
Explaining the discrepancy in the Nautical Almanac; will endeavor to make a clearer explanation in the next edition. Returns JH's son's memorandum.
Describes pendulum design. Believes [Henry] Kater's is the best. Regrets Russians want to make own pendulum. Discusses nominees, including [G. P.] Bond, for R.S.L. foreign membership.
Responds to GS's 1863-2-20, strongly recommending the support of the R.S.L. to defray part of the cost of publishing Richard Carrington's work.
Has heard that JH has to decide if the illustrations to his own paper on sun spots are necessary. Thinks they are of vital importance.
Is sorry to hear that the JHs have fever in the house. Hopes it will soon move away. Fever has been prevalent in Kent this year. Believes London is more healthy. Sends a problem.
Acknowledges receipt of JH's 1863-3-2, and another dealing with disagreement with William Hopkins [see GS's 1862-12-24 & JH's 1863-1-30].
Several of the illustrations in JH's Outlines Astr. have a familiar look. Doubtless all based on eternal laws. Comments on his own theories.
JH received and will insert HA's list of nebulae into JH's catalogue. Progress of catalogue. Wishes JH had earlier knowledge of [G. F. J. A.] Auwer's reduction of William Herschel's nebulae, which JH just received.
Sending a paper he has written on his ozone experiments; please communicate it to the R.S.L. if JH thinks it worthy. Would JH request the R.S.L. to re-suspend EL's certificate as he seems certain of some support from Council. Will soon complete his work on ferns.
Supports G. P. Bond of Harvard College for foreign membership of R.S.L.; proposes H. E. Sainte-Claire Deville for the Rumford Medal, for his development of a high temperature laboratory furnace applied to metallurgy and the 'disseverance' of the hydrogen and oxygen of water.
Hopes all is well. Has not seen the point about James Challis to which JH refers, but Challis has produced strange theorems.
Is grateful for the Memoirs. Hopes that JH will think his own work worthwhile when it appears.
Is grateful for JH's report on his paper. Regarding the plates for this paper.
Book he intended to write has had to be postponed as he has been asked to prepare a second edition of his Weather Book. Sends a proof of the revision of the 18th chapter.
