Talks about the very hot weather, and some matters of business that JH needs to work out with TM.
About the remarkably bright variable star, Eta Argus.
Some minor matters of astronomical business followed by an extended list of principles on which a constellation reform might be undertaken.
Describes his observational activities, especially the discovery of the variable nature of Eta Argo, and the rediscovery of the sixth satellite of Saturn.
JH's observations disagree with JD's 'Catalogues of Nebulae and Double Stars' [observed at Paramatta, Australia]. Believes errors lie in JD's work. Will send copy of JH's catalogue as soon as it is printed. [8pp of notes extracted by JH from JD's catalog; 7 pp of JH's comments, written in another hand, about these notes.]
Observations regarding the nebulous star 1281.
Intricate enquiries at Paramatta observatory are a waste of time. Instruments are not first class. Energy would be better spent cataloguing smaller magnitude stars and measuring double stars. Urges triangulation survey, important for Asian and Pacific geography, and investigation of weights and measures, to avoid litigation as Australia develops.
Reports observations of the 'remarkable' increase in magnitude of the 'nebulous' star Eta Argus.
