Summary:

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.]

Herschel8267

From:
Sir John Herschel
To:
George Gipps
Date:
[26 December 1837]
Source of text:
RS:HS 19.72
Summary:

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.
