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.
