Has spent much time on figures and annotations for JH's nebula catalogue [see GA's 1863-6-5]; JH needs information from a paper in GA's hands.

Was surprised at the large vote in support of a parliamentary bill to abolish the British Standard of weights and measures; JH hopes bill will not pass.

Thanks GA for receipt of some Royal Observatory publications; is still pushing the British metrical standard based on the length of the earth's polar axis [see JH's 1860-3-2].

Comments on the ease of calculation in geodesy in JH's version of the English system of units, and asks GA for some clarifications as JH prepares the seventh edition of his Outlines Astr.

JH wants to avoid using the meter in England; asks GA for the results of A. R. Clarke's calculations on the figure of the earth [see GA's 1863-10-7].

Comments on the possibility of employment in India for GA's son, Hubert.

Sends GA [see GA's 1863-11-21] JH's copy of the Melbourne telescope correspondence and reports; needs information from GA and Edwin Dunkin about the sun's motion, although JH questions some of Dunkin's work.

Has seen colored fringes on clouds described, and explained, in a journal. Does GA accept the explanation?

Thanks GA for the papers sent; asks GA to review enclosed note on solar motion [see JH's 1863-11-22].

Raises with GA the likelihood of an error in a date of a transit of Mercury in a paper by F. A. Winnecke.

Has been asked to reweigh the damaged Parliamentary standard pound weight; thinks that W. H. Miller would be a more suitable person to do the job.

Is trying to discover the train connections that will allow JH to come to a meeting of the Standards Committee without coming to London overnight. 'Catalogue of Nebulae' is now in proof state [see GA's 1863-10-9] and needs to be checked.

As JH has made minor changes in many calculated results, the proof sheets cannot be easily compared with the calculation sheets [see GA's 1864-2-6].

Is now too ill to come to the meeting of the Standards Committee; replies to GA's queries about how to clean up the pound [see GA's 1864-2-8].

Is unable to attend another meeting of the Standards Committee, due to severe illness; describes the best way to pack the standards away, and talks about the strange behavior of gallic acid.

Will miss yet another meeting of the Standards Committee due to illness [bronchitis]; W. H. Miller has brought JH up to date on the activity of the committee, and JH agrees with what is being done.

About observing a grain-shaped spot on the sun; greetings to Friedrich Winnecke.

Is very upset that JH's name has been attached to a group that wishes to import the 'French metrical system' into Britain; JH urges petitions or whatever is needed to retain the British system.

Compares earlier and more recent pound determinations and finds interesting results; wants GA's opinion on the accuracy of his work, as JH wishes to send it to the India committee.

Is working on a problem in polarized light, and finds his result disagreeing with F. J. D. Arago's third law; leads JH to think light cannot be undulatory in nature.
