About observing a grain-shaped spot on the sun; greetings to Friedrich Winnecke.
Raises with GA the likelihood of an error in a date of a transit of Mercury in a paper by F. A. Winnecke.
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].
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.
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.
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.
