Offers some possible explanation for what the unnamed observer saw [see GA's 1860-3-1].
Is arguing for the development of a British metrical system based on the length of the polar axis of the earth.
Asks for details about a strange drawing of Jupiter JH had seen at the Royal Observatory some months earlier, and offers some comments about Warren de La Rue's eclipse photographs.
A note with a copy of JH's article on telescopes for the Encyclopaedia Britannica, together with some papers to be forwarded to James Glaisher.
Has tried a number of different fractional projections, some more interesting than others [see GA's 1860-12-7].
